Figure BDA0002509102940000052
Figure BDA0002509102940000061
when the intelligent mobile terminal is placed on the wireless charging seat of the invention, the wireless charging seat can read the ID number of the intelligent mobile terminal through the wireless connection module, thereby calling the wireless charging parameters, including priority, maximum input voltage and maximum input current, stored in the device of the intelligent mobile terminal, if the ID number of the non-stored intelligent mobile terminal is read, the alarm can be L ED flicker or the speaker sends an alarm prompt tone to remind the user, the user can automatically judge whether the intelligent mobile terminal needs to be added into the default storage device and add parameters, then judge the total input charging power of all the intelligent mobile terminals connected to the wireless charging base in real time during wireless charging and the total output power of the wireless charging base during wireless charging, and operate according to the following steps:

2. When the total input charging power of all intelligent mobile terminals connected to the wireless charging base in real time during wireless charging is larger than the total output power efficiency value of the wireless charging base during wireless charging, the intelligent mobile terminals perform wireless charging according to the priority levels from high to low according to the set default priority levels (the artificially and temporarily set priority level is higher than the default priority level), at the moment, after the intelligent mobile terminals meeting the first priority level are wirelessly charged, when the total output power efficiency value of the wireless charging base during wireless charging has a margin, the intelligent mobile terminals meeting the second priority level are wirelessly charged preferentially, and so on, if a user temporarily needs to charge one of the intelligent mobile terminals (not the first priority level) first, the wireless charging priority level of the intelligent mobile terminal can be improved through the keys A and B, the wireless charging priority of other intelligent mobile terminals is reduced; if the locking key (key C) is pressed for a short time, the wireless charging priorities of all the intelligent mobile terminals connected at the time are the same.

If a certain intelligent mobile terminal completes the wireless charging process first, the maximum input power of the intelligent mobile terminal does not account for the total input charging power value of all intelligent mobile terminals connected by the formula I during wireless charging, and the wireless real-time charging power of the rest intelligent mobile terminals is increased to some extent at the moment, so that the charging speed of the rest intelligent mobile terminals is accelerated.
The user human intervention priority is higher than the default priority, which is as follows: the operation priority of a locking key (key C) is highest, and then the key A and the key B are temporarily intervened to adjust the priority; and finally, the priority is set by default. In addition, once the connected mobile equipment completely removes the wireless charging base or completely charges, the operation of the locking key (key C) and the operation of temporarily intervening and adjusting the priority of the key A and the key B are both invalid, and the priority is restored to the default set priority when the wireless charging is restored next time.
On the wireless charging seat, the wireless real-time charging power of the intelligent mobile terminal is required to be less than or equal to the maximum wireless charging output power of the equipment.
For example, the total output power value is 10W after being converted into loss, the wireless charging function is turned off according to the charging priority of the intelligent mobile terminal, for example, the lowest-level C device, the wireless device B with the middle priority can control the output charging power value of wireless charging at the side of the intelligent mobile terminal to be 3W, and then 7W is left for the intelligent device a with the highest priority.
The charging base calculates and allocates current wireless charging power values to the intelligent mobile terminals according to the priorities, specifically, the wireless charging power values of the intelligent mobile terminals are controlled by the intelligent mobile terminals, the priorities of the current intelligent devices and the allocated charging power values are fed back to the CPU of the intelligent mobile terminals through the wireless connection, and the CPU of the intelligent mobile terminals controls the current wireless charging power input of the intelligent mobile terminals.
