All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The charging power adjustment method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The following description will be made of the term "power delivery management (PD) adapter" appearing in the embodiments of the present application:

the PD adapter is a power adapter with PD protocol. The PD charging protocol is a Power transmission protocol published by a USB-IF organization, and a USB Power transmission (USB-Power Delivery) can increase the Power value output by a type-c interface to 100W.

USB-Power Delivery is one of the mainstream fast charging protocols, is a fast charging specification established by the USB-IF organization, and the USB PD adapter increases Power transmission through a USB cable and a connector to expand the Power supply capacity of a cable bus in USB application. The rapid charging specification can realize higher voltage and current, the transmitted power can reach 100W at most, and the transmission direction of the power can be freely changed.

From the function definition point of view, the core function of the PD adapter is PD quick charging.

The charging power adjusting method provided by the embodiment of the application can be applied to a scene that a power adapter charges a plurality of electronic devices at the same time.

For a scenario in which a power adapter charges a plurality of electronic devices simultaneously, it is assumed that the power adapter including 5 charging ports charges 3 electronic devices (electronic device 1, electronic device 2, and electronic device 3, respectively) simultaneously, and in the related art, a power value output by each port of the power adapter is preset in advance, so that the power adapter charges each electronic device according to the preset output power, for example, the output power preset by port 1 is a, and the power adapter charges electronic device 2 and electronic device 3 with power value a as electronic device 1 of port 1, and similarly, the power adapter charges electronic device 2 and electronic device 3 according to the output power preset by corresponding ports of electronic device 2 and electronic device 3 in advance. In the above process, the actual outputable power value of the power adapter is usually much larger than the sum of the powers preset in advance for the 3 ports, but since the output power value of the power adapter is preset in advance, the process of outputting the power is limited, which in turn wastes a large amount of available output power of the adapter, and reduces the efficiency of the electronic device in performing the charging task.

In this embodiment of the present application, when a power adapter is connected to 3 electronic devices, the power adapter receives 3 power request messages of the 3 electronic devices (one power request message is sent to the power adapter by one electronic device connected to the power adapter), and then, the power adapter determines a charging power allocation policy of the 3 electronic devices according to a sum of powers indicated by the 3 power request messages and a rated power value of the power adapter, and finally, the power adapter allocates charging power to the 3 electronic devices according to the charging power allocation policy. Therefore, the power adapter can determine the final power value distributed to each electronic device according to the sum of the actual powers of all the electronic devices, so that the output power of the power adapter can be utilized to the maximum extent on the premise of ensuring the reliability of the power adapter, and the efficiency of the electronic devices for executing charging tasks is improved.

The present embodiment provides a charging power adjustment method, as shown in fig. 1, the charging power adjustment method includes the following steps 301 to 303:

step 301: when M electronic devices are connected to a power adapter, the power adapter receives M pieces of power request information transmitted from the M electronic devices.

Wherein M is a positive integer.

In the embodiment of the present application, an electronic device to which power request information is connected is transmitted to the power adapter.

In this embodiment of the application, after the electronic device is connected to the port of the electronic device adapter, the electronic device sends power request information to the electronic device to request the power adapter to allocate power to the electronic device, so as to execute a charging task.

In the embodiment of the present application, the power value of the power requested by different power request information for power adapter allocation may be the same or different.

In this embodiment, the power adapter may include N ports, where N is greater than or equal to M.

In this embodiment, the power adapter may be a PD adapter, and the power adapter port may be a USB interface.

Step 302: and the power adapter determines a charging power distribution strategy according to the sum of the powers indicated by the M pieces of power request information and the rated power value of the power adapter.

In this embodiment of the application, after receiving M powers indicated by M power request messages, the power adapter may calculate a sum of the M powers, and determine a charging power allocation policy according to a magnitude relationship between the sum and a rated power value of the power adapter.

It is to be understood that when the sum is greater than the rated power value of the power adapter, the power adapter needs to appropriately reduce the amount of power value of the power allocated to each electronic device, and when the sum is less than or equal to the rated power value of the power adapter, the power adapter needs to allocate power to each electronic device in accordance with the power value requested in the power request information.

In one example, the power adapter may set a plurality of different charging power allocation policies in advance, and after receiving the power request information of the electronic device, determine the charging power allocation policy to be finally used when allocating power to the electronic device according to a size relationship between a power value of the power request information and a rated power value.

In another example, the power adapter may preset a determination condition of the charging power allocation policy, and after receiving the power request information of the electronic device, determine the charging power allocation policy to be finally used when allocating power to the electronic device according to the size relationship between the power value of the power request information and the rated power value and the determination condition

Step 303: and the power adapter distributes charging power to the M pieces of electronic equipment according to the charging power distribution strategy.

It is understood that the charging power allocated to the M electronic devices may be the same or different.

In the charging power adjustment method provided in the embodiment of the present application, when M electronic devices are connected to a power adapter, M power request information sent by the M electronic devices is received, then, the power adapter determines a charging power allocation policy of the M electronic devices according to a sum of powers indicated by the M power request information and a rated power value of the power adapter, and finally, the power adapter allocates charging power to the M electronic devices according to the charging power allocation policy, where M is a positive integer. Therefore, the power adapter can determine the final power value distributed to each electronic device according to the sum of the actual powers of all the electronic devices, so that the output power of the power adapter can be utilized to the maximum extent on the premise of ensuring the reliability of the power adapter, and the efficiency of the electronic devices for executing charging tasks is improved.

Optionally, in this embodiment of the present application, in the step 302, the method for adjusting charging power provided in this embodiment of the present application may further include the following steps 302a and 302 b:

step 302 a: and the power adapter determines the charging power allocation strategy to be a first charging strategy when the sum of the powers indicated by the M power request messages is less than or equal to the rated power value of the power adapter.

Illustratively, the first charging strategy is as follows: and distributing charging power to the M pieces of electronic equipment according to the power values corresponding to the M pieces of power request information.

It can be understood that, when the sum of the powers indicated by the M power request messages is less than or equal to the rated power value of the power adapter, the power adapter allocates power to each of the M electronic devices according to the power request message sent by the electronic device to the power adapter, that is, the power value of the allocated power is the power value requested in the power request message sent by the electronic device.

Illustratively, assuming that there are 3 electronic devices (i.e. M is 3) that need to be connected to the power adapter, namely, the electronic device 1, the electronic device 2, and the electronic device 3, respectively, and the power rating of the power adapter is 200W, the power adapter receives 3 power request information sent by the 3 electronic devices, the sum of the 3 power request information requests is 50W, 60W, 40W, the sum of the 3 power values is 150W, and is smaller than the power rating of the power adapter by 200W (i.e. the sum of the powers indicated by the M power request information is smaller than or equal to the power rating of the power adapter), the electronic device determines that the power is allocated according to the power value in the power request information of each electronic device, namely, the electronic device will allocate 50W to the electronic device 1, the electronic device will allocate 60W to the electronic device 2, the electronic device will allocate 40W of power to the electronic device 3.

Step 302 b: and the power adapter determines the charging power allocation policy to be a second charging policy when the sum of the powers indicated by the M power request messages is greater than the rated power value of the power adapter.

Illustratively, the second charging strategy is as follows: and distributing charging power to the M pieces of electronic equipment according to the proportional relation between the power values corresponding to the M pieces of power request information and the rated power value.

It can be understood that, when the sum of the powers indicated by the M power request information is greater than the rated power value of the power adapter, the power adapter compares the proportional relationship between the power values corresponding to the M power request information, divides the rated power value according to the proportional relationship, obtains the power value of the charging power corresponding to each electronic device, and allocates the charging power to the M electronic devices.

Exemplarily, assuming that there are 3 electronic devices (i.e. M is 3) that need to be connected to the power adapter, namely, electronic device 1, electronic device 2, and electronic device 3, respectively, and the rated power value of the power adapter is 200W, the power adapter receives 3 power request information sent by the 3 electronic devices, the sum of the 3 power request information requests is 100W, 60W, 80W, and the sum of the 3 power values is 240W, and is greater than the rated power value of the power adapter, which is 200W (i.e. the sum of the powers indicated by the M power request information is greater than the rated power value of the power adapter), the power adapter will calculate the proportional relationship between the power values requested by the 3 power request information, which are 42%, 25%, and 33%, respectively, the power adapter will divide the rated power value according to the proportional relationship, divide the rated power value into 84W, 50W and 66W, and allocates the above-mentioned divided 3 power values as power values of the charging power to 3 electronic devices, that is, the electronic device will allocate power 84W to the electronic device 1, the electronic device will allocate power 50W to the electronic device 2, and the electronic device will allocate power 66W to the electronic device 3.

Therefore, after the power adapter receives the power request information sent by the electronic equipment, the power adapter can compare the sum of the power values requested by the power request information with the rated power value which can be actually allocated by the power adapter, and allocate the maximum power of the quota to each electronic equipment according to the actually allocable upper limit, so that the power which can be allocated by the power adapter is utilized to the maximum extent on the premise of ensuring the reliability.

Optionally, in this embodiment of the present application, after the step 303, the method for adjusting charging power provided in this embodiment of the present application may further include the following steps 304 to 306:

step 304: the power adapter receives first request information sent by a target electronic device in the M electronic devices.

For example, the first request information is used to request the power adapter to adjust the charging power value allocated to the target electronic device to a target power value.

Illustratively, the first request message is a message sent to any electronic device (i.e., target electronic device) that has already been connected to the power adapter, and when the power of the currently received power adapter needs to be changed (for example, the charging power needs to be increased), the message is sent to the power adapter.

Step 305: the power adapter transmits negotiation information to the other electronic devices except the target electronic device among the M electronic devices.

Illustratively, the negotiation information is used to determine whether to allow adjustment of the charging power of the other electronic device.

For example, the negotiation information is information that the power adapter sends to the other electronic device after receiving the first request information, and queries whether the other electronic device agrees to change its charging power.

It can be understood that, if the negotiation information is respectively sent to each of the other electronic devices, the determining whether the charging power of the other electronic devices is allowed to be adjusted or not, which is indicated in the negotiation information, refers to: it is determined whether adjustment of the charging power of the one other electronic device is allowed.

Step 306: and the power adapter adjusts the charging power of the first electronic equipment under the condition of receiving the first electronic equipment determination information.

Illustratively, the other electronic devices include the first electronic device.

For example, the determination information indicates that the first electronic device allows the power adapter to adjust its charging power.

It can be understood that the charging power corresponding to different first electronic devices is different, and further, the charging power corresponding to different first electronic devices may be different whether before or after adjustment.

In one example, after receiving the first request message, the power adapter recalculates the charging power allocated to each electronic device according to the power value requested by the first request message, and informs the other electronic devices of the recalculated charging power that can be allocated to the other electronic devices in the form of negotiation message.

Firstly, the method comprises the following steps: in general, the first request message requests the power adapter to increase the charging power allocated to the electronic device, and accordingly, after increasing the allocated charging power for the electronic device, the first electronic device needs to correspondingly decrease the allocated charging power, so as to reserve the target electronic device with the portion of the charging power that needs to be increased.

Second, the specific information of the first electronic device may be some electronic devices other than the target electronic device, or may be specific information transmitted by all electronic devices other than the target electronic device.

Third, in the case where the determination information of the first electronic device is the determination information transmitted by the part of the electronic devices other than the target electronic device, in subsequent step 307 and step 308, the power adapter newly determines only the charging powers of the target electronic device and the part of the electronic devices (first electronic devices).

For example, after receiving the determination information of the first electronic device, the power adapter adjusts the charging power of the first electronic device, and specifically, the electronic device re-determines the charging power allocation policy and then allocates the charging power to the first electronic device, where the process of re-determining the charging power allocation policy may be performed with reference to the processes of step 302 to step 303.

It should be noted that, after the charging power allocation policy is re-determined, the power adapter may increase or decrease the charging power for the target electronic device, but after the charging power is increased or decreased, the adjusted charging power of the target electronic device is not necessarily the target power value. The method for determining that the target electronic device can increase or decrease the charging power by the power adapter is as follows: and comparing the size relationship between the target power value and the original power value of the target electronic equipment, if the target power value is larger than the original power value of the target electronic equipment, increasing the charging power, and if the target power value is larger than the original power value of the target electronic equipment, reducing the charging power.

Therefore, when the power adapter receives the condition that the electronic equipment needs to adjust the charging power of the power adapter, the power adapter can negotiate with other electronic equipment and flexibly adjust the charging power of all electronic equipment or part of electronic equipment, so that the power of the power adapter is flexibly and fully applied.

Optionally, in this embodiment of the present application, after the step 305, the method for adjusting charging power provided in this embodiment of the present application may further include the following step 307:

step 307: under the condition that the power adapter does not receive the determination information sent by the second electronic equipment within a preset time period, keeping the charging power of the second electronic equipment unchanged;

for example, the second electronic device is an electronic device that does not transmit the determination information to the power adapter among the other electronic devices.

For example, the predetermined time period may be preset by the electronic device or may be customized by the user, which is not limited in the embodiment of the present application.

For example, after the predetermined time period is reached, the power adapter adjusts only the charging power of the electronic device to which the determination information is transmitted, that is, adjusts only the charging power of the first electronic device.

Illustratively, as described in the above example, assuming that the electronic device 1 sends the first request message to the power adapter to request the power adapter to increase its power to 80W, at this time, the power adapter will send negotiation information to the electronic device 2 and the electronic device 3 (i.e. the other electronic devices) to inquire whether the electronic device 2 and the electronic device 3 allow to adjust the power value of the electronic device 2 and the power value of the electronic device 3 (i.e. the charging power of the other electronic devices), within 5 seconds (i.e. within the predetermined time period), the power adapter only receives the determination information of the electronic device 2 (i.e. the first electronic device) and does not receive the determination information of the electronic device 3 (i.e. the second electronic device), then the power adapter keeps the charging power of the electronic device 3 unchanged, and simultaneously adjusts the charging power of the electronic device 2 from 60W to 20W, meanwhile, the power value of the electronic device 1 is adjusted from 50W to 80W, that is, the power value of the electronic device 1 is 80W, the power value of the electronic device 1 is 20W, and the power value of the electronic device 1 is 40W.

Therefore, when the power adapter needs to adjust the power value of each electronic device according to the request of the target electronic device, each power value can be flexibly adjusted according to different requirements of different electronic devices, and the actual power requirement of each electronic device is guaranteed to the maximum extent.

Optionally, in this embodiment of the application, the adjusting the charging power of the first electronic device in the step 306 includes the following steps 306a and 306 b:

step 306 a: the power adapter calculates a first difference between a current power value of the target electronic device and the target power value.

Step 306 b: the power adapter adjusts the charging power of the first electronic device to a first charging power according to the first difference.

It is to be understood that the second difference between the first charging power and the charging power before the adjustment of the first electronic device is the same as the first difference.

The above target power value and the first electronic device may refer to the foregoing description, and are not described herein again.

For example, the second difference may be a sum of differences between all the first electronic devices and the corresponding first charging powers.

For example, 3 electronic devices, that is, the electronic device 1, the electronic device 2, and the electronic device 3 are connected to the power adapter, and the sum of the power values of the 3 electronic devices is equal to the rated power value of the power adapter. Assuming that the electronic device 1 is a target electronic device and the current power value thereof is 50W, the power adapter sends the first request message to the power adapter to request to increase the power value thereof to 70W (i.e., the target power value), the power adapter sends negotiation information to the electronic device 2 and the electronic device 3, and after receiving the determination information of the electronic device 2 and the electronic device 3 (i.e., the first electronic device), the power adapter adjusts the power values of the electronic device 2 and the electronic device 3 according to a difference value of 20W between the current power value of the target electronic device and the target power value (i.e., the first difference value), wherein the sum of the difference values between the adjusted power value of the electronic device 2 and the current power value and between the adjusted power value of the electronic device 3 and the current power value is 20W (i.e., the second difference value). For example, the charging power of the electronic device 2 may be reduced by 10W, and the charging power of the electronic device 3 may also be reduced by 10W.

It can be understood that, in the case that the target power value is greater than the current power value of the target electronic device, that is, in the case that the target electronic device needs to increase the charging power, the power adapter reduces the charging power of the first electronic device; when the target power value is smaller than the current power value of the target electronic device, that is, when the target electronic device needs to reduce the charging power, the power adapter increases the charging power of the first electronic device.

Optionally, in this embodiment of the present application, after the step 303, the method for adjusting charging power provided in this embodiment of the present application may further include the following step 308:

step 308: and the power adapter determines the charging power distribution strategy of the (M-X) electronic devices again according to the magnitude relation between the sum value of the powers indicated by the (M-X) power request information and the rated power value of the power adapter when the X electronic devices are separated from the power adapter, wherein X is a positive integer less than M.

For example, when X electronic devices are detached from the power adapter, the power adapter recovers power of the X electronic devices and manages the recovered power again.

In one example, the power adapter will recalculate the power that can be allocated to the remaining (M-X) electronic devices, i.e., the power adapter will reallocate power to the (M-X) electronic devices according to the power value requested in the power request information for the (M-X) electronic devices.

In one example, the power adapter will allocate the power of the X electronic devices to the remaining (M-X) electronic devices in a ratio of the previous power allocations of the remaining (M-X) electronic devices.

For example, the process of the power adapter re-determining the charging power distribution policy of the (M-X) electronic devices may be performed with reference to the processes of step 302 to step 303.

Therefore, when the electronic equipment is separated from the power adapter, the power adapter can timely use the power which is idle after the separation for other electronic equipment which is still charged on the power adapter, and the power which can be distributed by the power adapter can be fully utilized.

Optionally, in this embodiment of the present application, after the step 303, the method for adjusting charging power provided in this embodiment of the present application may further include the following step 309:

step 309: the power adapter transmits inquiry information to the (M-X) electronic devices when the X electronic devices are disconnected from the power adapter.

Illustratively, the query information is used to query whether the (M-X) remaining power adapters connected to the power adapter need to be increased.

Step 310: and after the power adapter receives the information which is sent by the third electronic equipment and confirms that the charging power is increased, re-determining the charging power distribution strategy of the third electronic equipment.

Illustratively, the third electronic device is an electronic device that transmits information confirming that the charging power is increased to the power adapter among the (M-X) electronic devices.

For example, the process of the power adapter re-determining the charging power distribution policy of the third electronic device may be performed with reference to the processes of step 302 to step 303.

Optionally, after the power adapter re-determines the charging power distribution policy of the third electronic device, the charging completion time length of each electronic device in the third electronic device may be determined according to the charging power distribution policy, and the completion time length information is sent to the corresponding electronic device.

It is understood that the above-described charge completion time period is a time period that it takes for each of the third electronic devices to be charged to 100%.

The present embodiment provides a charging power adjustment method, as shown in fig. 2, applied to an electronic device, the charging power adjustment method includes the following steps 401 and 402:

step 401: the electronic device transmits power request information to a power adapter connected to the electronic device.

Step 402: and the electronic equipment is charged according to the charging power distribution strategy indicated by the power adapter.

In the embodiment of the present application, the power request information and the charging power allocation policy may refer to the foregoing description, and are not described herein again.

According to the charging power adjustment method provided in the embodiment of the application, after the electronic device sends the power request information to the power adapter connected with the electronic device, the electronic device is charged according to the charging power distribution strategy indicated by the power adapter, so that the electronic device can receive different charging powers according to different charging powers required by the electronic device, and the charging efficiency of the electronic device is improved.

Optionally, in this embodiment, after the step 402, the method for adjusting charging power provided in this embodiment may further include the step 403:

step 403: the electronic equipment sends first request information to the power adapter.

For example, the first request information is used to request the power adapter to adjust the charging power value of the electronic device to a target power value.

In the embodiment of the present application, the first request information may refer to the foregoing description, and is not described herein again.

In the charging power adjustment method provided by the embodiment of the application, the power adapter can send the first request message when the electronic device needs to increase or decrease the charging power of the electronic device, so that the charging power of the power adapter is fully and flexibly utilized, and the charging efficiency is improved.
