step A4: calculating the total electric quantity ZD charged by the adaptive charging power of the mobile equipment when the mobile equipment arrives at the destination by using a calculation formula, wherein the calculation formula is ZD ═ alpha x (DL + SP × T), and alpha is a correction coefficient;
step A5: when the ratio of the total electric quantity ZD charged by the adaptive charging power of the mobile equipment to the battery capacity of the mobile equipment is more than 80%, the processor sends a normal charging signal to the wired charging module, and the wired charging module charges by adopting the adaptive charging power of the mobile equipment;
when the ratio of the total electric quantity ZD charged by the adaptive charging power of the mobile equipment to the battery capacity of the mobile equipment is less than 80%, the processor sends a quick charging signal to the wired charging module, and calculates the charging power CP through a calculation formula;
step A6: the calculation formula of the charging power is
Wherein β is a correction factor; the processor sets the charging power threshold YP when the calculated CP is>When the charging power is YP, the charging power CP exceeding range is calculated, the processor sends a quick charging signal to the wired charging module, the charging power threshold YP is sent to the wired charging module, and the wired charging module adopts the charging power threshold YP for charging;
and when the calculated CP is less than or equal to YP, the calculated charging power CP is not out of range, the processor sends a quick charging signal to the wired charging module, the charging power CP is sent to the wired charging module, and the wired charging module charges by adopting the charging power CP.
3. The vehicle-mounted charger according to claim 1, characterized in that: when the mode selection module is linked with the wireless charging module, the wireless charging module carries out wireless charging; specifically, the specific process of the wireless charging module during wireless charging comprises the following steps:
step B1: the wireless charging module acquires the linear distance between the mobile equipment and the vehicle-mounted charger and sends the linear distance between the mobile equipment and the vehicle-mounted charger to the processor;
step B2: the processor marks L after receiving the linear distance between the mobile equipment and the vehicle-mounted charger; the wireless charging module sets a wireless charging distance threshold YL, when the YL is less than or equal to L, the wireless charging module sends a distance exceeding signal to the controller, and the controller performs distance exceeding alarm;
when YL is larger than L, the wireless charging module obtains adaptive charging power of the mobile device;
step B3: the wireless charging module carries out wireless charging according to the adaptive charging power of the mobile equipment.
4. The vehicle-mounted charger according to claim 1, characterized in that: the data storage module is used for storing mobile equipment and adaptive power which are charged with the vehicle-mounted charger in a wired or wireless mode, and specifically, the working process of the data storage module comprises the following steps:
step C1: when the signal radiation module detects that the mobile equipment appears in the three-dimensional range with the radius of R, the data storage module sends an information storage signal to the data acquisition module;
step C2: after receiving the information storage signal, the data acquisition module sends the acquired model of the mobile equipment, whether the mobile equipment supports wireless charging, the current electric quantity of the mobile equipment and the adaptive charging power of the mobile equipment to the data storage module;
step C3: when the signal radiation module detects that the same mobile device enters the three-dimensional range with the radius of R again, the data storage module sends the model of the mobile device, whether the mobile device supports wireless charging, the current electric quantity of the mobile device and the adaptive charging power of the mobile device to the processor.
5. The vehicle-mounted charger according to claim 1, characterized in that: the mobile device information includes a model of the mobile device, whether the mobile device supports wireless charging, a current power level of the mobile device, and an adaptive charging power of the mobile device.
