Fig. 3 shows a flowchart for adjusting the second power information according to the charging speed according to the embodiment of the present invention.
According to an embodiment of the present invention, as shown in fig. 3, the adjusting the second power information of the first device according to the first charging speed information of the first device specifically includes:

s304, calculating a speed difference value between the first charging speed and the second charging speed to obtain charging speed difference value information;
s306, adjusting the second power information of the first equipment according to the charging speed difference information;
s308, judging whether the second power information exceeds the first power information;
and S310, if yes, setting the second power information according to the first power information.
It should be noted that, according to the number of wireless charging devices connected to the charger, after the first charging speed information of each wireless charging device is obtained, the sum of the first charging speed information of all the connected wireless charging devices is calculated, and then the average charging speed is obtained and recorded as the second charging speed information. And sequentially calculating charging speed difference information of the first charging speed information and the second charging speed information of the wireless charging equipment, and adjusting the second power information, namely the power upper limit value, of the wireless charging equipment by using the charging speed difference information. For clarity of explanation, the charging speed will be expressed in the form of a grade, for example, a 1-grade charging speed means an increase in the amount of electricity per second of 0.1%. The second power adjustment mode adopted by the invention is as follows: when the second power of the first device is 4W, the first charging speed is 4 levels, and the second charging speed is 5 levels, the charging speed difference is 1 level; the charging speed of the first device needs to be increased by 25% to reach the average charging speed; at this time, the charging upper limit power of the first device is required to be raised by 25%, that is, the second power is set to 5W. Finally, judging whether the adjusted second power exceeds the first power of the wireless charging equipment; if yes, the second power information is limited by the upper charging limit of the wireless charging equipment, and the second power information is only set to be the same as the first power information; the first power information is the highest allowable charging power of the wireless charging device.
According to an embodiment of the present invention, further comprising:
acquiring first electric quantity information of the first equipment;
obtaining first charging duration information according to the first electric quantity information and the first charging speed of the first equipment;
obtaining second charging duration information according to the quantity information of the first equipment and the first charging duration information;
judging whether the first charging duration information exceeds the second charging duration information or not;
if yes, setting the second power information according to the first power information.
The time required for filling the electric quantity can be calculated according to the electric quantity information and the charging speed of the wireless charging device and is recorded as first time information. According to the number of wireless charging devices connected with the charger, after the first charging time length information of each wireless charging device is obtained, the sum of the first charging time length information of all the connected wireless charging devices is calculated, and then the average charging time length is obtained and recorded as second charging time length information. If the first time length information of the wireless charging equipment exceeds the second time length information, the wireless charging equipment needs to increase the charging speed, so that the time length required by full charge can be shortened, and the gap between the wireless charging equipment and the time length required by full charge of other wireless charging equipment is shortened as far as possible. Then, the second power information is set according to the first power information of the wireless charging device, i.e., the size of the second power information is set closer to the first power information.
According to an embodiment of the present invention, further comprising:
acquiring third power information of the first equipment;
judging whether the third power information is larger than the second power information;
if yes, setting the wireless charging power of the first equipment according to the second power information;
if not, setting the wireless charging power of the first equipment by the third power information.
It should be noted that, the third power information is a charging power value which is acceptable in real time by the wireless charging device and is obtained by the charger communicating with the wireless charging device in the charging process, and generally speaking, the wireless charging device sends real-time allowable charging power to the charger according to the self electric quantity state and the physical state. If the third power information of the wireless charging equipment is larger than the second power information, namely the acceptable charging power value is larger than the charging power value provided by the charger, the charger sets the charging power according to the second power information to supplement electric energy to the wireless equipment; if the third power information of the wireless charging device is not greater than the second power information, that is, the acceptable charging power value is not greater than the charging power value provided by the charger, the charger sets the charging power according to the third power information to supplement electric energy to the wireless device.
According to an embodiment of the present invention, further comprising:
when the first device belongs to the quick charging device;
obtaining output voltage information according to the wireless charging power of the first equipment;
according to the voltage information, calculating feedback parameter information of the voltage regulating unit;
and adjusting the electrical characteristics of the feedback pins of the voltage regulating unit according to the feedback parameter information.
In addition, for the fast charging device, a mode of increasing the output voltage of the charger is generally adopted to achieve the purpose of increasing the output power. When the first device is a fast charging device, a corresponding output voltage value can be calculated according to the wireless charging power required to be output. The voltage regulating unit is usually a voltage regulating chip; for example, TMI2286; the effect of adjusting the output voltage of the voltage regulating chip is achieved by adjusting the feedback circuit through the processor. According to the required output voltage value, the feedback parameters of the feedback circuit can be calculated through the voltage regulation rule of the voltage regulation chip. According to the feedback parameters, the feedback circuit is regulated, so that the purpose of regulating the electrical characteristics of the feedback pins of the voltage regulating chip is achieved; wherein the electrical characteristics of the feedback pin are commonly referred to as voltage values. Generally, in practical application, the purpose of adjusting the voltage value of the feedback pin is achieved by adjusting the resistance value of a resistor connected with the feedback pin.
It is worth mentioning that the method further comprises:
wirelessly communicating with the first device via at least one wireless communication unit;
the wireless charging communication unit is connected with at least two power transmitters;
wireless communication is performed with a power receiver of the first device via the power transmitter in accordance with a preset communication protocol using a backscatter modulation principle.
It should be noted that, the processor communicates with the wireless charging device through at least one wireless communication unit; the wireless communication unit generally realizes one-to-many communication function, that is, one wireless communication unit can communicate with a plurality of wireless charging devices at the same time; for example, chip D9612. The charging comprises at least 2 power transmitters and the wireless charging equipment comprises a power receiver, and in practical application, the power transmitters and the power receiver are planar coils, and the purpose of power transmission is achieved by using an inductive coupling mode. The backscattering modulation communication is a low-power-consumption modulation and transmission technology designed by utilizing the backscattering principle of video signals, and is widely applied to the field of communication of the Internet of things. Modulated communication between the power transmitter and the power receiver may be achieved by backscatter communication techniques.
It is worth mentioning that the method further comprises:
calculating the sum of the power of the second charging power of all the first devices according to the quantity information of the first devices to obtain fourth power information;
judging whether the fourth power information exceeds preset power threshold information or not;
if so, sorting according to the first charging speed of the first equipment in ascending order or sorting according to the first charging time length of the first equipment in descending order;
and adjusting second power information of the first equipment at the tail of the ascending queue according to the power difference value between the fourth power information and the preset power threshold information.
After the second power information of each wireless charging device is obtained according to the number of wireless charging devices connected to the charger, the sum of the second power information of all the connected wireless charging devices is calculated and recorded as fourth power information. The fourth power is a sum of upper limit values of charging power provided by the charger to the wireless charging device. In addition, the preset power threshold information is determined by the charger circuit, and is an upper limit value of the total power which can be output by the charger circuit when a plurality of devices are charged simultaneously. If the fourth power information exceeds the preset power threshold information, which means that the total power of the required charging exceeds the total power available by the charger, the second power information provided by the charger for the first device needs to be adjusted. And according to the first charging speed information of the first equipment, sorting in an ascending order mode or sorting in a descending order mode according to the first charging time length, and finding out the wireless charging equipment with the highest charging speed or the shortest charging time length. And reducing the second power information of the wireless charging equipment with the fastest charging speed or the shortest charging duration through the power difference value between the fourth power information and the preset power threshold information.
It is worth mentioning that the method further comprises:
acquiring temperature information of a first power transmission unit of first equipment;
judging whether the temperature information exceeds a preset temperature threshold value or not;
if yes, adjusting second power information of the first device according to a preset power adjustment table.
It should be noted that, temperature information of a first power transmission unit of a first device is obtained, where the first power transmission device is a power receiver of the first device. And judging whether the temperature information exceeds a preset temperature threshold, wherein the preset temperature threshold is a safety threshold serving as the working temperature of the power receiver. When the temperature information is higher than the temperature threshold value, a mode of reducing the charging power is needed to achieve the purpose of reducing the temperature; and obtaining second power information adjusted by the first equipment by searching a preset power adjustment table. For example, when the second power information is 5W and the temperature threshold is 40 ℃; when the temperature value of the first electric energy transmission unit is 42 ℃, the second power information is adjusted to be 4.6W by inquiring the power adjustment table; when the temperature value of the first power transmission unit is 45 ℃, the second power information is adjusted to be 4W by inquiring the power adjustment table. As can be seen from the above, the more the temperature information is higher than the temperature threshold, the larger the power down-regulation amplitude is.
