Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described in the following in conjunction with the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. The following embodiments and features of the embodiments may be combined with each other without conflict.
The invention provides a charging method, power supply equipment and a computer readable storage medium, which are used for solving the technical problem that in the prior art, the power supply efficiency of the power supply equipment is low because the load electronic equipment does not support real-time broadcasting to change power. The charging method comprises the steps of detecting access of the load electronic equipment, distributing power to the load electronic equipment and outputting the power, obtaining actual charging power of the load electronic equipment, adjusting distribution power of the power supply equipment in response to mismatching of the charging power and the distribution power, and sending a reset instruction to the load electronic equipment so that the load electronic equipment can identify the adjusted distribution power and pull the load for charging according to the adjusted distribution power. The details are set forth below.
Referring to fig. 1, fig. 1 is a flowchart illustrating a charging method according to a first embodiment of the present invention.
S101, detecting access of the load electronic equipment, distributing power to the load electronic equipment and outputting.
When the power supply equipment detects that the load electronic equipment is accessed, power is distributed to the load and output to supply power to the load electronic equipment.
And S102, acquiring the actual charging power of the load electronic equipment.
After the power supply equipment outputs the distributed power to the load electronic equipment, the actual charging power carried by the load electronic equipment is detected and obtained to identify whether the distributed power is matched with the charging power, so that the power supply power of the power supply equipment is improved or the electric energy is saved.
And S103, adjusting the distribution power of the power supply equipment in response to the mismatch of the charging power and the distribution power.
The power distribution of the power supply equipment is equivalent to the power which can be provided for the load electronic equipment currently broadcast by the power supply equipment, and the charging power of the load electronic equipment is equivalent to the power which is used for charging and is pulled by the load electronic equipment after the load electronic equipment recognizes the power distribution broadcast by the power supply equipment, namely the power which is obtained by pulling the load of the load electronic equipment and is applied to charging is the charging power. It is readily understood that the distribution power of the power supply device may be different from the charging power of the load electronic device.
The mismatch between the charging power and the distribution power may specifically include a case where a difference between the charging power and the distribution power is greater than a certain range (such as a minimum unit power) or other situations affecting power supply efficiency, which will not be described herein. When the charging power is not matched with the distribution power, the distribution power of the power supply equipment can be adjusted in response to the fact that the charging power is not matched with the distribution power, so that the distribution power of the power supply equipment is matched with the actual charging power of the load electronic equipment, the situation that electric energy is wasted when the distribution power is larger than the charging power is relieved, the situation that the power supply efficiency is low even the load electronic equipment cannot be charged due to the fact that the distribution power is smaller than the charging power is relieved, and therefore the power supply efficiency of the power supply equipment is improved.
And S104, sending a reset instruction to the load electronic equipment so that the load electronic equipment can identify the adjusted distributed power and pull the load for charging according to the adjusted distributed power.
The current load electronic devices on the market can mostly support the power supply device to broadcast and change the distribution power in real time, namely when the power supply device recognizes that the distribution power is not matched with the charging power, the power supply device can adjust the distribution power and re-broadcast the distribution power, and at the moment, the load electronic device can recognize the broadcasted changed distribution power and can correspondingly adjust the charging power which is pulled and loaded by the load electronic device.
For example, when another load electronic device is connected to the power supply device, the power supply device adjusts the distributed power distributed to each load electronic device, and when the previously connected load electronic device recognizes the adjusted distributed power, the power supply device adjusts the charging power carried by the load electronic device according to the adjusted distributed power.
The situation that the partial load electronic equipment does not support the power supply equipment to broadcast and change the distributed power in real time still exists, that is, after the power supply equipment adjusts the distributed power, the load electronic equipment cannot recognize that the distributed power is changed, and cannot adjust the charging power of the load according to the adjusted distributed power, so that the compatibility problem exists. In order to solve the above-mentioned problem, in this embodiment, a reset instruction may be sent to the load electronic device, so that the load electronic device may identify the adjusted distributed power of the power supply device, adjust the power pulled according to the adjusted distributed power, and change the actual charging power thereof, that is, pull-load charging according to the adjusted distributed power.
The specific embodiment of sending the reset instruction to the load electronic device will be described later.
In this embodiment, adaptive power supply can be performed on the load electronic device, for example, when the load electronic device does not support real-time broadcasting of the modified power, that is, when the modified power allocated by the power supply device cannot be identified, the power supply device sends a reset instruction to the load electronic device, so that the load electronic device is re-connected to the power supply device after being reset, and then the adjusted power allocated can be identified, and load pulling and charging can be performed according to the adjusted power allocated, so that when the load pulling power of the load electronic device is smaller than the power allocated by the power supply device, the power supply efficiency of the power supply device is lower, or the load pulling power of the load electronic device is larger than the power allocated by the power supply device, the power supply device enters a protection mode to stop power supply, and therefore the situation that the load electronic device does not support real-time broadcasting of the modified power is improved, and the power supply efficiency of the power supply device is improved.
Referring to fig. 2, fig. 2 is a flow chart of a charging method according to a second embodiment of the invention.
In the present embodiment, the charging policy statistics table is previously established and stored in the power supply apparatus, that is, the charging policy statistics table is previously stored on the power supply apparatus. The charging policy statistics may include device identification and charging configuration parameters. For example, the device identifier may include device information such as a brand name, a Vendor Identity (VID), and a Product Identity (PID) of the device, and the charging configuration parameter may include a minimum charging power threshold and a charging rule such as whether the device supports real-time broadcasting to change the allocated power.
The minimum charging power threshold indicates that the load electronic device cannot be charged if the charging power of the input load electronic device is lower than the minimum charging power threshold, for example, the minimum charging threshold of the load electronic device is 45W, and the load electronic device cannot be charged if the distribution power output from the power supply device to the load electronic device is smaller than 45W.
The contents of the charging policy statistics table are shown by way of example in table 1 below:
table 1 charging policy statistics table
The device may write a remark column in the case of whether the device supports real-time broadcasting to change the allocated power, or may additionally add a list of tables for filling in the case of whether the device supports real-time broadcasting to change the allocated power, which is not limited herein.
It is easy to understand that the load electronic device, such as a notebook computer, stores the corresponding device identifier and the charging configuration parameter in advance, that is, the device identifier and the charging configuration parameter are stored in the load electronic device in advance. Alternatively, the device identifier of the load electronic device may be obtained by a discovery identity (Discovery Identify) message in a Power Delivery (PD) specification, and may also be obtained by other manners, which are not limited herein.
Optionally, the charging policy statistics Table pre-stored in the Power supply device may be a super dynamic Table (Power Table) or the like, so that when the Power supply device identifies that the device identifier and the charging configuration parameter of the load electronic device are not stored in the charging policy statistics Table, the Power supply device can acquire the device identifier and the charging configuration parameter of the load electronic device, and write the device identifier and the charging configuration parameter of the load electronic device into the charging policy statistics Table. Alternatively, the update may be performed by an Application (APP) or the like.
S201, detecting access of the load electronic equipment.
When the power supply equipment detects that the load electronic equipment is accessed, power is distributed to the load electronic equipment and output to supply power to the load electronic equipment.
When the load electronic equipment is accessed, the equipment identifier of the load electronic equipment can be obtained, so that the charging configuration parameters corresponding to the load electronic equipment are obtained according to the equipment identifier, the charging configuration parameters comprise the minimum charging power threshold value and whether the equipment supports real-time broadcasting and power change and the like, namely, the charging configuration parameters corresponding to the equipment identifier of the load electronic equipment are searched based on a charging strategy statistical table. If the device identifier of the load electronic device cannot be acquired, it is considered that there is no special requirement, and if there is a power output, the charging is enabled, and step S205 is performed (this embodiment is not specifically shown in the figure).
And S202, judging whether the remaining power to be distributed of the power supply equipment is smaller than the minimum charging power threshold of the load electronic equipment.
If the remaining power to be allocated of the power supply device is not less than the minimum charging power threshold of the load electronic device, step S205 is executed, and if the remaining power to be allocated of the power supply device is less than the minimum charging power threshold of the load electronic device, step S203 is executed.
The minimum charging power threshold may be obtained in the above step, and if the current load electronic device has no minimum charging power, it means that the load electronic device is not particularly limited, and if the load electronic device can be charged only by power output, step S205 is executed.
The power supply equipment can compare the residual power to be distributed with the minimum charging power threshold value of the load electronic equipment, so that corresponding actions are independently made according to the states of the power supply equipment and the load electronic equipment, the distributed power is reasonably output to each load electronic equipment, and the power supply efficiency is improved.
And S203, acquiring the charging current of the accessed load electronic equipment.
If the remaining power to be distributed of the power supply equipment is smaller than the minimum charging power threshold value of the load electronic equipment, the distributed power which can be output by the current power supply equipment is considered to be insufficient to supply power to the load electronic equipment, namely the load electronic equipment cannot be charged, and the charging current which is accessed to the load electronic equipment before the distributed power is acquired and monitored. Meanwhile, a notification containing relevant information can be pushed to a mobile terminal or an APP of the user, for example, the user is informed that the remaining power to be distributed of the current power supply equipment is insufficient to supply power to the newly accessed load electronic equipment, and after the charging of other load electronic equipment is completed, the power is supplied to the load electronic equipment. In an alternative embodiment, other information that the load electronic device may change during the charging process may also be obtained, which is not limited to obtaining the charging current, such as the remaining power, of the load electronic device, and will not be described herein.
And S204, if the time that the charging current is smaller than the first threshold value is larger than the second threshold value, stopping supplying power to the load electronic equipment with the charging current smaller than the first threshold value, and distributing the recovered power to the newly connected load electronic equipment.
In the process of monitoring the prior access to the load electronic equipment, if the time that the charging current of the load electronic equipment is smaller than the first threshold value is larger than the second threshold value, the load electronic equipment can be considered to be fully charged, the load electronic equipment with the charging current smaller than the first threshold value is stopped from being charged, the distribution power output to the load electronic equipment is recovered, the recovered power is distributed to the newly accessed load electronic equipment, namely, the load electronic equipment accessed in the step S201, so that the distribution power is reasonably output to each load electronic equipment accessed to the power supply equipment, the power supply to the prior access load electronic equipment is ensured, and the power supply to the load electronic equipment accessed backwards after the prior access load electronic equipment is fully charged is ensured, so that the use experience of a user is improved.
In an alternative embodiment, priority may be set for each charging interface of the charging device, so as to preferentially allocate output and allocated power to the load electronic device connected to the charging interface with high priority, so as to preferentially ensure that the load electronic device connected to the charging interface with high priority can achieve quick charging.
Optionally, the priority of each charging interface may be initially set at the time of delivery, or the priority of each charging interface may not be set at the time of delivery, may be customized by the user and may be modified, or the priority of each charging interface may be initially set at the time of delivery, and the priority of each charging interface may be modified by the user.
And S205, distributing power to the load electronic equipment and outputting.
The distributed power which can be distributed to the load electronic equipment is output to the load electronic equipment so as to reasonably supply power to the load electronic equipment, so that each load electronic equipment can be effectively charged, the power supply efficiency of the power supply equipment is improved, and the use experience of a user is improved.
And S206, acquiring the actual charging power of the load electronic equipment.
The power supply device can acquire the actual charging power of the load electronic device while distributing and outputting the power to the load electronic device so as to identify whether the distribution power of the power supply device is matched with the charging power of the load electronic device, so that when the distribution power is not matched with the charging power, the distribution power of the power supply device is adjusted, and when the distribution power is matched with the charging power, the power supply device continuously outputs the current distribution power to the load electronic device. An embodiment of adjusting the allocated power is specifically described below.
S207, obtaining a difference value between the charging power and the distribution power.
And acquiring a difference value between the distribution power of the power supply equipment and the charging power of the load electronic equipment, and judging whether the charging power is matched with the distribution power.
S208, judging whether the difference value between the charging power and the distribution power is larger than/equal to the minimum unit power.
If the difference between the charging power and the distribution power is greater than or equal to the minimum unit power, step S209 is executed, and if the difference between the charging power and the distribution power is not greater than or equal to the minimum unit power, the charging power and the distribution power are considered to be matched, and the process is ended.
Specifically, when the difference between the allocated power and the charging power is greater than/equal to the minimum unit power, the charging power and the allocated power are not considered to be matched, the allocated power is recovered/increased in response to the mismatch, the recovered/increased power value is an integer multiple of the minimum unit power, and when the difference is smaller than the minimum unit power, the charging power is considered to be matched with the allocated power, and the charging power of the power supply equipment is not required to be regulated temporarily, so that the charging method is more reasonable, and the use experience of a user is improved.
The minimum unit power may be stored in the power supply device in advance, and may be 1W, 2W, 3W, or the like, which is not limited herein. In a specific embodiment, the minimum unit power is 3W, if the difference between the allocated power of the power supply device and the charging power of the load electronic device is detected to be 16W, the allocated power is adjusted, and the power value is recovered/increased to be an integer multiple of the minimum unit power (3W) until the difference between the allocated power and the charging power is smaller than the minimum unit power, that is, the difference between the allocated power and the charging power is smaller than 3W, and the allocated power and the charging power are considered to be matched, so that the allocated power does not need to be recovered/increased continuously.
The fact that the distribution power is matched with the charging power does not mean that the distribution power and the charging power are required to be identical in value, and the distribution power output by the power supply equipment can still be dynamically changed, if the distribution power is required to be identical to the charging power, the distribution power needs to be continuously adjusted, so that a certain difference between the distribution power and the charging power is allowed, and the distribution power and the charging power can be considered to be matched within a certain range (such as the minimum unit power in the invention) so as to improve the charging method.
S209, judging whether the charging power is larger than the distribution power.
If the charging power is greater than the distribution power, step S210 is performed, and if the charging power is not greater than the distribution power, step S212 is performed.
The current distribution power of the power supply equipment and the charging power carried by the load electronic equipment are compared to autonomously decide whether the distribution power should be recovered or the distribution power should be increased, so that the power supply efficiency of the power supply equipment is improved.
And S210, taking the minimum unit power as a step, and increasing the distributed power.
When the charging power of the load electronic device is greater than the distribution power of the power supply device, the current power pulled by the load electronic device is indicated to be greater than the power distributed to the load electronic device by the power supply device, and the power supply device can be caused to enter a protection mode to stop supplying power for a long time. Therefore, the distributed power is increased by taking the minimum unit power as a step, and the difference between the distributed power and the charging power is reduced, so that the power supply device is favorable for stably supplying power to the load electronic device, and the reliability of the power supply device is improved.
S211, judging whether the distributed power is larger than/equal to the charging power, and the difference value is smaller than the minimum unit power.
If the allocated power is greater than or equal to the charging power and the difference is less than the minimum unit power, step S215 is performed, and if the allocated power is not greater than or equal to the charging power and the difference is less than the minimum unit power, step S210 is repeatedly performed.
After the power distribution is increased by taking the minimum unit power as the step, judging whether the current power distribution is larger than/equal to the charging power and the difference value is smaller than the minimum unit power, if so, considering that the power distribution of the power supply equipment is matched with the charging power of the load electronic equipment, the power supply equipment can stably supply power to the load electronic equipment, and if not, repeating the step S210, namely, increasing the power distribution again by taking the minimum unit power as the step.
That is, if the charging power is greater than the allocated power, the allocated power is gradually increased with the minimum unit power as a step until the allocated power is greater than/equal to the charging power, and the difference value between the allocated power and the charging power is smaller than the minimum unit power, so that the allocated power is matched with the charging power, and the power supply to the load electronic device is facilitated to be stably performed. Specifically, taking the example that the minimum unit power is 3W, when the allocated power is not matched with the charging power, the allocated power is increased by 3W each time, and whether the current allocated power is matched with the charging power or not is judged after the allocated power is increased each time, if the allocated power is matched with the charging power, the allocated power is stopped being increased, and if the allocated power is still not matched with the charging power, the allocated power is continuously increased by 3W. By adopting the design, the power supply device can avoid the influence on the stability of power supply by increasing the value of the distributed power at a time to be overlarge, thereby being beneficial to stably supplying power to load electronic equipment.
Of course, in an alternative embodiment, the power may be directly multiplied by the integer of the minimum unit power to increase the power, or the difference between the power and the charging power may be directly increased, which is not limited herein.
S212, judging whether the difference is greater than the minimum unit power of two times.
If the difference is greater than twice the minimum unit power, step S213 is executed, and if the difference is not greater than twice the minimum unit power, the process ends.
When the charging power is not greater than the distribution power, namely, the distribution power of the power supply equipment is greater than the charging power of the load electronic equipment, whether the difference value between the two is greater than the minimum unit power of two times is further judged. If the difference between the two is smaller than the minimum unit power of two times, the distribution power of the power supply equipment is considered to be matched with the charging power of the load electronic equipment, and the distribution power of the power supply equipment is not required to be adjusted.
The purpose of judging whether the difference is greater than twice the minimum unit power is to adjust the distribution power when the difference is greater than twice the minimum unit power due to possible fluctuation of the distribution power of the power supply equipment, so that unstable distribution power can be relieved, power can be supplied to load electronic equipment stably, and the use experience of a user is improved.
And S213, taking the minimum unit power as a step, and reducing the distributed power.
When the charging power of the load electronic device is not greater than the distribution power of the power supply device, the fact that the power distributed to the load electronic device by the current power supply device remains is indicated, the distribution power can be reduced by taking the minimum unit power as a step, namely, the distribution power of the redundant part can be recovered, and the part of power can be distributed to other accessed load electronic devices, and the limitation is not made here, so that the power supply efficiency of the power supply device is improved.
Alternatively, the minimum unit power in the present step and the minimum unit power in step S210 may be different values. For example, the minimum unit power when the power is increased may be 3W, and the minimum unit power when the power is decreased may be 4W, which is not limited herein.
S214, judging whether the distributed power is larger than/equal to the charging power, and the difference value is smaller than the minimum unit power.
If the allocated power is greater than or equal to the charging power and the difference is less than the minimum unit power, step S215 is performed, and if the allocated power is not greater than or equal to the charging power and the difference is less than the minimum unit power, step S213 is repeatedly performed.
After the distributed power is reduced by taking the minimum unit power as the step, judging whether the distributed power is larger than/equal to the charging power, and the difference value is smaller than the minimum unit power, if so, considering that the distributed power of the power supply equipment is matched with the charging power of the load electronic equipment, the power supply equipment can stably supply power to the load electronic equipment, and if not, repeating the step S213, namely reducing the distributed power again by taking the minimum unit power as the step.
That is, if the charging power is smaller than the allocated power and the difference is greater than the minimum unit power of two times, the allocated power is gradually reduced with the minimum unit power as a step until the allocated power is greater than/equal to the charging power and the difference is smaller than the minimum unit power, so that the allocated power is matched with the charging power, and the power supply to the load electronic device is facilitated to be stably performed.
Specifically, taking the case that the minimum unit power is 3W as an example, when the allocated power and the charging power are not matched, recovering the allocated power of 3W each time is equivalent to reducing the value of the allocated power by 3W each time, judging whether the current allocated power and the charging power are matched after the allocated power is recovered each time, if the allocated power is matched with the charging power, stopping recovering the allocated power, and if the allocated power is still not matched with the charging power, continuing to recover the allocated power of 3W. By adopting the design, the method can avoid the overlarge value of the once recovered and distributed power and influence the stability of power supply, thereby being beneficial to stably supplying power to load electronic equipment.
Of course, in an alternative embodiment, the allocated power may be directly recovered as an integer multiple of the minimum unit power, or the difference between the allocated power and the charging power may be directly recovered, so as to simplify the charging method, which is not limited herein.
It is noted that there is a minimum charge power threshold for a portion of the load electrons, and as previously explained, if the charge power efficiency of the current load electron device is less than the minimum charge power threshold, then the load electron device cannot be charged.
The information about the minimum charging power threshold of the load electronic device may be included in the charging configuration parameters as described above, and when the corresponding charging configuration parameters (in the charging policy statistics table) are obtained according to the device identifier of the load electronic device, the information about the minimum charging power threshold of the load electronic device may be obtained.
Therefore, when the distribution power of the power supply equipment is regulated, the regulated distribution power is controlled to be larger than/equal to the minimum charging power threshold value of the load electronic equipment, so that the load electronic equipment can be charged when being connected to the power supply equipment.
In an alternative embodiment, in this step, it is determined whether the difference between the allocated power and the charging power is smaller than the minimum unit power, or alternatively, it is determined whether the difference between the allocated power and the charging power is smaller than the minimum unit power by two times, so as to improve the stability of power supply.
S215, determining that the load electronic device can identify the adjusted distributed power.
If the load electronic device can identify the adjusted distributed power, the load electronic device is considered to be able to pull the load for charging according to the adjusted distributed power, the flow ends, and if the load electronic device cannot identify the adjusted distributed power, step S216 is executed.
The information about whether the load electronic device can identify the adjusted distributed power may be included in the charging configuration parameters as described above, and when the corresponding charging configuration parameters (in the charging policy statistics table) are obtained according to the device identifier of the load electronic device, the information about whether the load electronic device can identify the adjusted distributed power, that is, whether the load electronic device supports real-time broadcasting of the modified power, may be obtained.
And S216, sending a reset instruction to the load electronic equipment.
And when the load electronic equipment cannot identify the adjusted distributed power, sending a reset instruction to the load electronic equipment so that the load electronic equipment identifies the adjusted distributed power and pulls the load for charging according to the adjusted distributed power.
Alternatively, the load electronic device may be controlled to go offline and re-access the power supply device, and the charging power is output to the load electronic device according to the adjusted distributed power. That is, the load electronic equipment is controlled to be offline and re-connected to the power supply equipment, which is equivalent to realizing a one-time plugging process of the load electronic equipment in a software manner, so that the load electronic equipment is re-connected to the power supply equipment, the adjusted distributed power can be identified, and the charging power is pulled according to the adjusted distributed power, so that charging is realized, the influence of the load electronic equipment caused by that the real-time broadcasting of the power change is not supported can be relieved, the power supply efficiency of the power supply equipment is improved, and the safety of the power supply equipment can be also protected.
Optionally, in the process that the load electronic device is connected to the power supply device to charge, the number of times of resetting the load electronic device can be controlled, so that the influence on the use experience of a user and the service life of the load electronic device due to excessive resetting times is avoided. For example, in the charging process of the load electronic device, the number of times of sending the reset instruction to the load electronic device after adjusting the allocated power may not exceed 3 times, which is not limited herein.
In an alternative embodiment, if the charging configuration parameters of the accessed load electronic device are obtained, it is identified that the load electronic device does not support real-time broadcasting of the change power, and in the charging process of the load electronic device, the distribution power distributed to the load electronic device is not adjusted, so as to avoid the situation that the power supply device changes the distribution power and the load electronic device cannot be identified.
For example, referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of a charging method according to the present invention.
The total power output by the power supply device 31 is 115W, and the charging interfaces of the three load electronic devices 32, namely, the charging interface 311, the charging interface 312 and the charging interface 313, are correspondingly connected with the load electronic device 321, the load electronic device 322 and the load electronic device 323.
When the power supply device 31 is connected to the load electronic device 321 through the charging interface 311, the load electronic device 321 can obtain the maximum distributed power 115W, when the power supply device 31 is connected to the charging interface 312 through the load electronic device 322, the load electronic device 321 and the load electronic device 322 can respectively obtain the distributed power 57W, and when the power supply device 31 is connected to the charging interface 313 through the load electronic device 323, the load electronic device 321, the load electronic device 322 and the load electronic device 323 respectively obtain the distributed power 40W.
If the load electronic device 321 and the load electronic device 322 have the minimum charging power threshold 45W, the load electronic device 321 and the load electronic device 322 cannot be charged when the load electronic device 321 and the load electronic device 322 each obtain the distributed power 40W. Alternatively, the allocated power to each charging interface may be adjusted, the allocated power of each charging interface 311 and 312 is 50W, the allocated power of each charging interface 313 is 15W, and further, as the power of the load electronic device 32 increases gradually, the allocated power of each charging interface may be adjusted to be 45W for the charging interface 311, 45W for the charging interface 312, and 25W for the charging interface 313.
In the foregoing example charging process in which the charging interface 311 and the charging interface 312 obtain the distribution power 50W, and the charging interface 313 obtains the distribution power 15W, considering that the charging interface 311 and the charging interface 312 still obtain sufficient distribution power when the load electronic device 323 is finally connected to the power supply device 31, as described in the steps S203 and S204, the charging currents of the connected load electronic device 321 and the load electronic device 322 are obtained, if the time for detecting whether the charging current is smaller than the first threshold is larger than the second threshold, so that the load electronic device 321 (or the load electronic device 322) with the charging current smaller than the first threshold is stopped when the charging current is smaller than the second threshold, and the recovered power is distributed to the load electronic device 323, and if the distribution power of the charging interface 311 is 45W, the distribution power of the charging interface 312 is 45W, and the distribution power of the load electronic device 313 is 45W, the load electronic device 323 can be reasonably distributed to the load electronic device 323, that is the load electronic device 323, and the load electronic device 323 can be reasonably charged with the charging interface 25, and the load electronic device 323 can be simultaneously charged with the minimum power, and the load electronic device 323 can be reasonably distributed to the load electronic device 32, and the load electronic device can be charged with the load electronic device 323.
If the minimum charging power threshold of the load electronic device 323 is greater than 25W, then, in view of the load electronic device 323 being the last to be connected to the power supply device 31, the charging currents of the connected load electronic device 321 and load electronic device 322 are obtained as set forth in the above steps S203 and S204, and if the charging current is less than the first threshold for a time greater than the second threshold, the power supply to the load electronic device 321 (or the load electronic device 322) with the charging current less than the first threshold is stopped, and the recovered power is distributed to the load electronic device 323 to reasonably supply power to each load electronic device 32.
Taking the example that the load electronic device 321 cannot recognize the adjusted distributed power, after the distribution of the overcharge interface 311 is adjusted, a reset instruction may be sent to the load electronic device 321 so that it can pull the charge according to the adjusted distributed power.
In an alternative embodiment, the flow of the charging method of the present invention may also be implemented not completely according to the steps in the above embodiments. For example, when the load electronic device is connected to the power supply device, power may be distributed to the load electronic device and output, and then it is determined whether the distributed power is smaller than the minimum charging power threshold value after the distribution, that is, steps S202 to S204 in the above embodiment may be performed after step S205, which is not limited herein. Of course, other steps in the above embodiment may also be changed in the execution order or adjusted thereon, and will not be described herein.
Referring to fig. 4, fig. 4 is a flowchart illustrating a charging method according to a third embodiment of the invention.
S401, detecting the temperature of the power supply equipment and/or the load electronic equipment.
When the power supply equipment charges the load electronic equipment, the power supply equipment and/or the load electronic equipment have high temperature due to factors such as environment, high output power of the power supply equipment, high input power of the load electronic equipment and the like, and certain potential safety hazards exist, so that the temperature of the power supply equipment and/or the load electronic equipment can be detected and monitored, and the current temperature condition of the power supply equipment and/or the load electronic equipment can be known in real time.
And S402, in response to the temperature of the power supply equipment and/or the load electronic equipment being higher than a temperature threshold value, reducing the distributed power of the power supply equipment.
When the temperature of the power supply equipment and/or the load electronic equipment is detected to be higher than the temperature threshold value, the power supply equipment and/or the load electronic equipment is considered to be overheated currently, potential safety hazards exist, the distributed power of the power supply equipment can be reduced in response to the potential safety hazards, the load electronic equipment can detect the reduction of the distributed power of the power supply equipment, and further the load pulling power of the power supply equipment can be reduced, so that the condition that the temperature of the power supply equipment and/or the load electronic equipment is higher is relieved, and the safety is improved. If the current load electronic device does not support implementing the broadcast modified power and cannot identify the broadcasted modified distributed power, a reset instruction may be sent to the load electronic device, for example, to control the load electronic device to be offline and re-access the power supply device, i.e., simulate a physical plug-in load electronic device, so that the load electronic device can identify the modified distributed power and pull the load according to the modified distributed power for charging, as described in the above embodiments.
Referring to fig. 5, fig. 5 is a flowchart illustrating a charging method according to a fourth embodiment of the invention.
S501, acquiring the electric quantity information of the load electronic equipment and the current time.
The method for obtaining the electric quantity information of the load electronic equipment can be used for obtaining the electric quantity condition, the charging current and the like of the electronic equipment, and is not limited herein, and the method for obtaining the current time refers to obtaining the time point of the current moment, such as Beijing time, new York time and the like.
And S502, in response to the electric quantity information of the load electronic equipment being larger than the electric quantity information threshold value and the current time being in the time threshold value range, suspending charging.

For example, the time threshold range may be selected to be between 23:00 and 07:00 Beijing time, the electric quantity information threshold is 80%, so as to suspend charging at night, avoid potential safety hazards caused by overcharging the load electronic device at night, improve safety, obtain electric quantity information and current time of the load electronic device, and if the electric quantity of the load electronic device is 80% at this time and is in the time 23:30 Beijing, the electric quantity information of the load electronic device is greater than the electric quantity information threshold, and the current time is in the time threshold range, the power supply device suspends outputting electric energy to the load electronic device, that is, suspends charging to the load electronic device. It should be noted that, in this embodiment, the electric quantity information threshold value and the time threshold value range are illustrated, and in actual use, the electric quantity information threshold value and the time threshold value range may be selected according to actual requirements, and may be customized by a user according to own requirements.
Further, when the fact that the electric quantity information of the load electronic equipment is larger than the electric quantity information threshold value and the current time is within the time threshold value range is detected, corresponding information can be pushed to the user to remind the user of the current state, whether to suspend charging is selected by the user, namely, the user can select the power supply equipment to suspend charging to the load electronic equipment, and the power supply equipment can also be selected to continue charging to the load electronic equipment, so that the use experience of the user is improved.
And S503, detecting that the current time is out of a time threshold range, and charging the load electronic device by the power supply device.
After the power supply device pauses charging the load electronic device, the time may continue to be detected such that the power supply device resumes charging the load electronic device when the time is outside of the time threshold range. Taking the example that the time threshold range in step S502 is between 23:00 and 07:00 Beijing time, before 07:00, the power supply device pauses charging the load electronic device, and when the current time is detected to be 07:01 or 07:00, the power supply device can charge the load electronic device.
In an embodiment, the charging method of the present invention may further detect a load pulling power of the load electronic device, and when the load pulling power of the load electronic device is greater than a preset value, consider that the load pulling power required by the load electronic device is greater, and affect charging of other load electronic devices, and may consider that the charge current is less than a preset value, and consider that the electric quantity is sufficient, and reduce the distribution power to the load electronic device, or may set a preset value of a charging duration, and pause the distribution of power to the load electronic device, or reduce the distribution power to the load electronic device, so as to distribute sufficient distribution power to other load electronic devices, and improve the power supply efficiency.
In summary, the invention can identify the device identifier of each load electronic device connected to the power supply device, and adjust the distribution power distributed to each load electronic device according to the corresponding charging strategy in the charging strategy statistics table, if the load electronic device which does not support real-time broadcasting to change the power is connected to the load electronic device, and when the distribution power is changed by broadcasting, a reset instruction is sent to the load electronic device, so that the load electronic device identifies the adjusted distribution power, the condition that the load electronic device does not support real-time broadcasting to change the power is improved, and the power supply efficiency of the power supply device is improved. That is, the present invention can realize dynamic allocation of power and can improve compatibility of a power supply device.
