The wireless charging device can be a wireless charging stand, a wireless charging post and the like.
Referring to fig. 1, fig. 1 is a schematic flow chart of a charging control method according to an embodiment of the present disclosure. The charging control method is applied to a wireless charging device, the wireless charging device includes a plurality of wireless charging units for performing wireless charging, as shown in fig. 1, a flow of the charging control method provided by the embodiment of the present application may be as follows:
101. temperature values of a plurality of wireless charging units are obtained.
In the embodiment of the present application, the wireless charging unit is shown in a physical form of a coil, and may be a circular coil, an elliptical coil, or the like. When a user places a powered device within the charging range of any wireless charging unit, the wireless charging device detects the powered device placed by the user through the wireless charging unit, and wirelessly charges the powered device within the charging range of the wireless charging unit through the wireless charging unit.
When the powered device is detected, the wireless charging device may perform the detection according to the Qi standard, and the wireless charging device controls each wireless charging unit to emit energy at a time interval of 400ms to detect whether an object exists in a charging range of each wireless charging unit, and if an object exists, further determine whether the object is a legal receiver, and if so, mark the object as the powered device.
For example, referring to fig. 2, the wireless charging device includes 4 wireless charging units, which are a wireless charging unit 1, a wireless charging unit 2, a wireless charging unit 3, and a wireless charging unit 4, and the user places the mobile phone 1 on the surface of the wireless charging device at a position corresponding to the wireless charging unit 3 and places the mobile phone 2 on the surface of the wireless charging device at a position corresponding to the wireless charging unit 4. At this time, the wireless charging apparatus will detect the mobile phone 1 through the wireless charging unit 3, mark the mobile phone 1 as the powered apparatus 1, detect the mobile phone 2 through the wireless charging unit 4, and mark the mobile phone 2 as the powered apparatus 2.
It should be noted that, when the wireless charging unit is wirelessly charged, the wireless charging unit continuously generates heat to continuously raise the temperature, and in order to avoid the damage of the wireless charging unit caused by an excessively high temperature and even burn the powered device, in the embodiment of the present application, a charging control method is provided to perform charging control on the wireless charging unit to suppress the temperature rise trend thereof.
In the embodiment of the application, the temperature sensors for acquiring the temperature values are respectively arranged corresponding to the wireless charging units, so that when the wireless charging equipment acquires the temperature values of the plurality of wireless charging units, the temperature values of the wireless charging units can be acquired from the temperature sensors corresponding to the wireless charging units.
In addition, in order to avoid mutual heat transfer among the wireless charging units, each wireless charging unit can be isolated by adopting a heat insulating material, so that heat transfer to other wireless charging units is avoided.
102. And determining a target wireless charging unit of the plurality of wireless charging units, wherein the temperature value is greater than a preset temperature value.
In the embodiment of the application, a preset temperature value is set, and the preset temperature value is used for describing whether the temperature value of the wireless charging unit is too high or not so as to determine whether to perform charging control or not. It should be noted that, the value of the preset temperature value can be empirically determined by those skilled in the art, and can be set to 60 ℃.
After the wireless charging equipment acquires the temperature values of the plurality of wireless charging units, for any wireless charging unit, the temperature value corresponding to the wireless charging unit is compared with a preset temperature value, and if the temperature value corresponding to the wireless charging unit is larger than the preset temperature value, the wireless charging unit is marked as a target wireless charging unit needing charging control.
103. When the N target wireless charging units are determined, dividing a preset time period into N time periods, and respectively associating the divided N time periods with the N target wireless charging units, wherein N is an integer greater than or equal to two.
In the embodiment of the application, when the wireless charging device determines N target wireless charging units from a plurality of wireless charging units included in the wireless charging device, that is, the N target wireless charging units need to be charged and controlled, so as to suppress a temperature increase trend of the N target wireless charging units. N is an integer greater than or equal to two and is less than or equal to the number of wireless charging units included in the wireless charging device.
When the charging control is performed on the N target wireless charging units, the wireless charging equipment firstly divides a preset time period into N time periods, and associates the N divided time periods with the N target wireless charging units respectively, wherein the time length of any one divided time period is less than the sum of the time lengths of other time periods. It should be noted that, for any target wireless charging unit, its associated time period is the time period in which it can perform wireless charging.
The value of the preset duration period is not specifically limited in the embodiments of the present application, and a person skilled in the art can take a suitable value according to actual needs, and when time periods are divided, the preset duration period can be divided into N time periods with the same duration, or the preset duration period can be divided into N time periods with different durations.
For example, assuming that the preset time period is configured to be 100 milliseconds, and the wireless charging device includes four wireless charging units in total, if two target wireless charging units are determined from the four wireless charging units, the preset time period may be divided into two time periods with a time length of 50 milliseconds, and the two divided time periods are respectively associated with the two determined target wireless charging units, in addition, the preset time period may be divided into two time periods with a time length of 30 milliseconds and 70 milliseconds, and the two divided time periods are associated with the two determined target wireless charging units, and so on.
104. And controlling each target wireless charging unit to perform wireless charging within the associated time period and stop wireless charging outside the associated time period in each preset time period.
In the embodiment of the application, after the wireless charging device completes the division of the N time periods and associates the N divided time periods with the N target wireless charging units, for any target wireless charging unit of the N target wireless charging units, at every preset time period, the wireless charging device controls the target wireless charging unit to perform wireless charging in the associated time period, and stops the wireless charging outside the associated time period (or inside the associated time periods of other target wireless charging units).
For example, referring to fig. 3, the preset time period is denoted as T, it is assumed that the wireless charging device includes four wireless charging units, two target wireless charging units (the target wireless charging unit 1 and the target wireless charging unit 2, respectively) are determined from the four wireless charging units, the preset time period T is divided into two time periods (the time period T1 and the time period T2, respectively) with equal time duration, the time period T1 is associated with the target wireless charging unit 1, and the time period T2 is associated with the target wireless charging unit 2. In this way, for the target wireless charging unit 1, the wireless charging device will control the target wireless charging unit 1 to perform wireless charging in the time period T1 of each preset duration period T, and stop the wireless charging outside the time period T1 (i.e. within the time period T2); for the target wireless charging unit 2, the wireless charging device will control the target wireless charging unit 2 to perform wireless charging in the time period T2 of each preset time period T, and stop the wireless charging outside the time period T2 (i.e. within the time period T1).
As can be seen from the above, the wireless charging device in the embodiment of the present application may determine, from a plurality of wireless charging units included in the wireless charging device, N target wireless charging units having temperature values greater than a preset temperature value, and divide a preset time period into N time periods, and associate the N time periods with the N target wireless charging units, respectively, so that in each preset time period, each target wireless charging unit is controlled to perform wireless charging in the associated time period, and the wireless charging is stopped outside the associated time period. In this way, for any one of the target wireless charging units, it performs wireless charging within a shorter associated time period, and stops wireless charging outside the longer associated time period. Therefore, the trend of temperature rise is restrained by the time-sharing charging mode, and the safety of wireless charging of the wireless charging equipment is improved.
In one embodiment, "dividing the preset duration period into N time periods and associating the divided N time periods with the N target wireless charging units, respectively" includes:
(1) acquiring a first proportional relation of the N target wireless charging units based on temperature values;
(2) dividing a preset time period into N time periods with time in a first proportional relation;
(3) according to a first proportional relationship, the divided N time periods are respectively associated with the N target wireless charging units in a reverse order.
As an alternative embodiment, the wireless charging device divides the time period based on the temperature value of each target wireless charging unit.
For example, assuming that the wireless charging device determines 3 (i.e., N is 3) target wireless charging units from a plurality of wireless charging units included in the wireless charging device, which are the target wireless charging unit 1, the target wireless charging unit 2, and the target wireless charging unit 3, if the first ratio of the target wireless charging unit 1, the target wireless charging unit 2, and the target wireless charging unit 3 based on the temperature values is 7:8:9, the preset time period may be divided into 3 time periods with a first ratio of time duration, which are the time period 1, the time period 2, and the time period 3, where the time period 1: period 2: the time period 3 is 7:8:9, and then the divided 3 time periods are respectively associated with the 3 target wireless charging units in a reverse order according to a first proportional relationship, that is, the time period 3 is associated with the target wireless charging unit 1, the time period 2 is associated with the target wireless charging unit 2, and the time period 1 is associated with the target wireless charging unit 3.
In one embodiment, "dividing the preset duration period into N time periods and associating the divided N time periods with the N target wireless charging units, respectively" includes:
(1) acquiring the residual electric quantity of the powered device corresponding to the N target wireless charging units;
(2) acquiring a second proportional relation of the N target wireless charging units based on respective corresponding residual electric quantities;
(3) dividing a preset time period into N time periods with time length in a second proportional relation;
(4) and according to a second proportional relation, the divided N time periods are respectively associated with the N target wireless charging units in a reverse order.
As an alternative embodiment, the wireless charging apparatus divides the time period based on the remaining capacity of the power receiving apparatus corresponding to each target wireless charging unit.
For example, assuming that the wireless charging device determines 3 (i.e., N is 3) target wireless charging units from the plurality of wireless charging units included in the wireless charging device, which are the target wireless charging unit 1, the target wireless charging unit 2, and the target wireless charging unit 3, respectively, if the second proportional relationship among the target wireless charging unit 1, the target wireless charging unit 2, and the target wireless charging unit 3 based on the remaining power of their respective powered devices is 7:8:9, the preset time period may be divided into 3 time periods with the second proportional relationship among the time periods 1, 2, and 3, where the time period 1: period 2: the time period 3 is 7:8:9, and then the divided 3 time periods are respectively associated with the 3 target wireless charging units in a reverse order according to the second proportional relationship, that is, the time period 3 is associated with the target wireless charging unit 1, the time period 2 is associated with the target wireless charging unit 2, and the time period 1 is associated with the target wireless charging unit 3.
When the wireless charging device acquires the remaining capacity of the powered device corresponding to the N target wireless charging units, for any target wireless charging unit of the N target wireless charging units, the wireless charging device sends a capacity acquisition request to the powered device corresponding to the target wireless charging unit (i.e., the powered device located within the charging range of the target wireless charging unit), where the capacity acquisition request is used to instruct the powered device to return to the current remaining capacity. Therefore, the remaining capacity of the power receiving equipment corresponding to the N target wireless charging units can be acquired.
In one embodiment, "dividing the preset duration period into N time periods and associating the divided N time periods with the N target wireless charging units, respectively" includes:
(1) acquiring the residual electric quantity of the powered device corresponding to the N target wireless charging units;
(2) respectively carrying out weighted summation on the temperature value and the residual electric quantity corresponding to each target wireless charging unit according to a first preset weighting factor corresponding to the residual electric quantity and a second weighting factor corresponding to the temperature value to obtain a weighted sum value corresponding to each target wireless charging unit;
(3) acquiring a third proportional relation of the N target wireless charging units based on the respective corresponding weighted sum values;
(4) dividing a preset time period into N time periods with time length in a third proportional relation;
(5) and according to a third proportional relation, the divided N time periods are respectively associated with the N target wireless charging units in a reverse order.
As an optional implementation manner, the wireless charging device divides the time period by combining the remaining capacity of the powered device corresponding to each target wireless charging unit and the temperature value of each target wireless charging unit.
For example, assuming that the wireless charging device determines 3 (i.e., N is 3) target wireless charging units from the plurality of wireless charging units included in the wireless charging device, which are the target wireless charging unit 1, the target wireless charging unit 2, and the target wireless charging unit 3, respectively, if the third proportional relationship of the target wireless charging unit 1, the target wireless charging unit 2, and the target wireless charging unit 3 based on their respective corresponding weighted sum values is 7:8:9, the preset time period may be divided into 3 time periods with a third proportional relationship of time duration, which are the time period 1, the time period 2, and the time period 3, where the time period 1: period 2: the time period 3 is 7:8:9, and then the divided 3 time periods are respectively associated with the 3 target wireless charging units in a reverse order according to a third proportional relationship, that is, the time period 3 is associated with the target wireless charging unit 1, the time period 2 is associated with the target wireless charging unit 2, and the time period 1 is associated with the target wireless charging unit 3.
When the wireless charging device acquires the remaining capacity of the powered device corresponding to the N target wireless charging units, for any target wireless charging unit of the N target wireless charging units, the wireless charging device sends a capacity acquisition request to the powered device corresponding to the target wireless charging unit (i.e., the powered device located within the charging range of the target wireless charging unit), where the capacity acquisition request is used to instruct the powered device to return to the current remaining capacity. Therefore, the remaining capacity of the power receiving equipment corresponding to the N target wireless charging units can be acquired.
It should be noted that, for the first preset weighting factor and the second preset weighting factor, an absolute value of the first preset weighting factor may be set to be greater than an absolute value of the second preset weighting factor, and the first preset weighting factor is positive, the second preset weighting factor is negative, and specific values of the first preset weighting factor and the second preset weighting factor are not specifically limited here.
In one embodiment, during the period of "controlling each target wireless charging unit to perform wireless charging in its associated time period and stop wireless charging outside its associated time period every preset time period", the method further includes:
when the temperature value of a target wireless charging unit in the N target wireless charging units is detected to be smaller than a second preset temperature value, the target wireless charging unit with the temperature value smaller than the second preset temperature value is controlled to continuously charge, wherein the second preset temperature value is smaller than the preset temperature value.
In this embodiment of the application, a second preset temperature value for controlling the target wireless charging unit to perform wireless charging according to a normal charging mode is further provided, where the second preset temperature value is configured to be smaller than the preset temperature value, and for a specific value of the second preset temperature value, a person skilled in the art may take a suitable value according to actual needs, for example, when the preset temperature value is configured to be 60 ℃, the second preset temperature value may be configured to be 30 ℃.
The wireless charging equipment also detects the temperature values of the N target wireless charging units in real time during the charging control period aiming at cooling on the determined N target wireless charging units, and if the temperature value of one target wireless charging unit is smaller than a second preset temperature value in the N target wireless charging units, the target wireless charging unit with the temperature value smaller than the second preset temperature value is controlled to be continuously charged, and the mark of the target wireless charging unit with the temperature value smaller than the second preset temperature value is cancelled.
In an embodiment, after "determining a target wireless charging unit of the plurality of wireless charging units, which has a temperature value greater than a preset temperature value", the method further includes:
(1) when a target wireless charging unit is determined, dividing a preset time period into a charging time period and a stopping time period;
(2) and controlling the target wireless charging unit to perform wireless charging in the charging time period and stop the wireless charging in the stopping time period in each preset time period.
As an alternative embodiment, when the wireless charging apparatus determines only one target wireless charging unit from the plurality of wireless charging units included in the wireless charging apparatus, only the only one target wireless charging unit needs to be subjected to charging control.
When the target wireless charging unit is subjected to charging control, firstly, a preset time period is divided into a charging time period and a stopping time period. As the name implies, the charging time period is a time period for the target wireless charging unit to perform wireless charging, and the stopping time period is a time period for the target wireless charging unit to stop wireless charging.
It should be noted that, in the embodiment of the present application, a value of the preset duration period is not specifically limited, and a person skilled in the art may take a suitable value according to actual needs, and in addition, for the divided charging time period and the divided stopping time period, durations occupied by the charging time period and the stopping time period may be the same or different.
For example, assuming that the preset duration period is configured to be 100 milliseconds, the first 50 milliseconds of the preset duration period may be divided into the charging time period, the last 50 milliseconds of the preset duration period may be divided into the stopping time period, the first 30 milliseconds of the preset duration period may also be divided into the charging time period, the last 70 milliseconds of the preset duration period may be divided into the stopping time period, and the like.
After the division of the charging time period and the stopping time period is completed, the wireless charging equipment controls the determined target wireless charging unit to perform wireless charging in the charging time period of each preset time period, and controls the determined target wireless charging unit to stop wireless charging in the stopping time period of each preset time period.
In one embodiment, "dividing the preset length of time period into the charging period of time and the stopping period of time" includes:
(1) determining a first charging time corresponding to the temperature value of the target wireless charging unit according to the corresponding relation between the preset temperature value and the charging time;
(2) calculating a first time length difference value of a preset time length period and a first charging time length;
(3) the preset time period is divided into a charging time period with the time length being the first charging time length and a stopping time period with the time length being the first time length difference.
As an optional time period dividing manner, in the embodiment of the present application, the time period is divided according to the temperature value of the target wireless charging unit.
It is easy to understand that, if the temperature value of the target wireless charging unit is higher, it is more necessary to suppress the temperature rising trend of the target wireless charging unit as soon as possible, in the embodiment of the present application, according to the requirements of different temperature values on suppressing the temperature rising trend, the corresponding relationship between the temperature value and the charging time length is preset for dividing the charging time period and the stopping time period. Wherein, the higher the temperature value, the shorter the corresponding charging time.
When the wireless charging device divides the charging time period and the stopping time period, firstly, the charging time period corresponding to the temperature value of the target wireless charging unit is determined according to the corresponding relation between the preset temperature value and the charging time period, and is recorded as a first charging time period. And then, calculating a time length difference value between the preset time length period and the first charging time length, and recording the time length difference value as the first time length difference value, so that the preset time length period is divided into a charging time period with the time length being the first charging time length and a stopping time period with the time length being the first time length difference value.
For example, assuming that the preset time period is 100 milliseconds, and the first charging time period is 40 milliseconds according to the corresponding relationship between the preset temperature value and the charging time period, the first time difference between the preset time period and the first charging time period may be calculated to be 60 milliseconds, and therefore, the preset time period may be divided into a stop time period with a time period of 60 milliseconds and a charging time period with a time period of 40 milliseconds. Thus, in a preset time period, the target wireless charging unit will perform wireless charging in the charging time period with a shorter time period, and stop the wireless charging in the stopping time period with a longer time period.
In an embodiment, before determining the first charging duration corresponding to the temperature value of the target wireless charging unit according to the corresponding relationship between the preset temperature value and the charging duration, the method further includes:
(1) acquiring the residual electric quantity of the powered device of the target wireless charging unit, and judging whether the acquired residual electric quantity is greater than or equal to a preset electric quantity;
(2) if the judgment result is yes, determining a first charging time corresponding to the temperature value of the target wireless charging unit according to the corresponding relation between the preset temperature value and the charging time.
It is easy to understand that the operation of the powered device needs to consume power, and when the remaining power is too low, the powered device cannot continue to operate normally. Therefore, a preset electric quantity can be set to determine the priority of charging and cooling, and the stop time period and the charging time period are divided according to the priority in a corresponding dividing mode. It should be noted that, in the embodiment of the present application, a value of the preset electric quantity is not specifically limited, and may be set by a person skilled in the art according to actual needs, for example, the preset electric quantity may be set to 30% of the total electric quantity of the powered device.
The wireless charging device firstly sends a power acquisition request to the powered device, wherein the power acquisition request is used for indicating the powered device to return the current remaining power of the powered device. After receiving the remaining power returned by the powered device, determining whether the remaining power is greater than or equal to a preset power, if so, that is, when the remaining power is greater than or equal to the preset power, determining that the remaining power of the powered device is sufficient to maintain normal operation of the powered device, and determining that the priority of temperature reduction is higher than the priority of charging, at this time, determining a first charging duration corresponding to the temperature value of the target wireless charging unit according to a corresponding relationship between a preset temperature value and the charging duration, so as to divide the preset duration period into a stopping time period and a charging time period according to the first charging duration, and perform charging control.
For example, assuming that the preset power is configured to be 30%, the obtained remaining power of the powered device is 45%, obviously, the remaining power of the powered device is greater than the preset power, at this time, the wireless charging device determines a first charging duration corresponding to the temperature value of the target wireless charging unit according to a corresponding relationship between the preset temperature value and the charging duration, divides the stop time period and the charging time period according to the first charging duration, and performs charging control.
In an embodiment, after determining whether the acquired remaining power is greater than or equal to a preset power, "the method further includes:
(1) if the judgment result is negative, determining a second charging time corresponding to the residual electric quantity according to the preset corresponding relation between the residual electric quantity and the charging time;
(2) calculating a second time length difference value of the preset time length period and the second charging time length;
(3) and dividing the preset time period into a charging time period with the time length of the second charging time length and a stopping time period with the time length of the second time length difference.
There is a continuing need for time slot partitioning based on a remaining power of a powered device. It is easy to understand that, for a powered device, the lower the remaining capacity thereof, the higher the urgency of charging the powered device. Therefore, in the embodiment of the present application, a corresponding relationship between the remaining power and the charging time period is preset, and is used for dividing the charging time period and the stopping time period. Wherein, the lower the residual capacity is, the longer the corresponding charging time period is, and the higher the residual capacity is, the shorter the corresponding charging time period is.
Correspondingly, after the wireless charging device completes the judgment of the residual electric quantity and the preset electric quantity, if the judgment result is negative, that is, the residual electric quantity of the powered device is less than the preset electric quantity, it is determined that the residual electric quantity of the powered device is insufficient to maintain the normal operation of the powered device, and it is determined that the charging priority is higher than the cooling priority. At this time, according to a preset corresponding relationship between the remaining capacity and the charging duration, the charging duration corresponding to the remaining capacity is determined and recorded as a second charging duration. And then, calculating a time length difference value between the preset time length period and the second charging time length, and recording the time length difference value as the second time length difference value, so that the preset time length period is divided into a charging time period with the time length being the second charging time length and a stopping time period with the time length being the second time length difference value.
For example, assuming that the preset time period is 100 milliseconds, the second charging time period is determined to be 60 milliseconds according to the preset corresponding relationship between the remaining power and the charging time period, and then the second time period difference between the preset time period and the second charging time period is calculated to be 40 milliseconds, so that the preset time period can be divided into a charging time period with a time period of 60 milliseconds and a stopping time period with a time period of 40 milliseconds. Thus, in a preset time period, the target wireless charging unit will perform wireless charging in the charging time period with a longer time length, and stop the wireless charging in the stopping time period with a shorter time length.
