step S322, if the duration of the current running of the vehicle is longer than a second preset duration, controlling to enter a low-power charging mode;
step S323, if the duration of the current running of the vehicle is between the first preset duration and the second preset duration, calculating a duration required by the wireless charging electronic device to be full of the low-power charging mode, and controlling to enter the low-power charging mode and/or the normal charging mode according to the duration required by the wireless charging electronic device to be full of the low-power charging mode.
In this embodiment, the high-power charging mode, the low-power charging mode, and the normal charging mode may be set according to the rated charging power adaptability of the vehicle-mounted wireless charger, which is not particularly limited herein. For example, if the rated charging power of the vehicle-mounted wireless charger is 50W, the high-power charging mode may be set to operate at 50W, the low-power charging mode may be set to operate at 10W, and the normal charging mode may be set to operate at 25W. The first preset duration may be 0.5 hour, and the second preset duration may be 3 hours, which is set according to practical application conditions, and is not specifically limited herein. For example, if the current driving time of the vehicle is less than 0.5 hour, controlling the vehicle-mounted wireless charger to operate in a high-power charging mode to charge the mobile phone; if the time length of the vehicle when the vehicle runs is longer than 3 hours, controlling the vehicle-mounted wireless charger to operate in a low-power charging mode; if the time length of the vehicle when the vehicle runs is between 0.5 hour and 3 hours, for example, the time length of the vehicle when the vehicle runs is 2 hours, calculating the time length required for filling the mobile phone in the low-power charging mode, and controlling to enter the low-power charging mode and/or the normal charging mode according to the time length required for filling the mobile phone. It should be noted that, the time length required for filling the mobile phone is calculated by adopting the low-power charging mode, so as to ensure that the battery of the mobile phone is charged and protected at any time as long as the mobile phone can be charged by adopting the low-power charging mode, thereby prolonging the service life of the battery of the mobile phone.
Further, referring to fig. 4, step S323 includes:
step S3231, obtaining the residual electric quantity of the wireless charging electronic equipment, and calculating the time period for the wireless charging electronic equipment to be full of the low-power charging mode;
step S3232, if the required full charge time is less than or equal to the current running duration of the vehicle, controlling to enter a low-power charging mode;
and step S3233, if the full charge required time is longer than the current running duration of the vehicle, controlling to enter a normal charging mode and a low-power charging mode.
In this embodiment, if the current driving duration of the vehicle is between 0.5 hours and 3 hours, the remaining power of the mobile phone is obtained, and meanwhile, the duration that the mobile phone is full of the required duration in a low-power charging mode is calculated; the full-on required duration is then compared to the current travel duration to control the charging mode of the vehicle-mounted wireless charger. For example, if the vehicle is traveling for 2 hours, the mobile phone is fully charged in the low-power charging mode for 1.5 hours, and then the vehicle-mounted wireless charger is controlled to charge the mobile phone in the low-power charging mode. If the time length of the vehicle when the vehicle runs is 2 hours, the mobile phone is full of the required time length of 2.5 hours in a low-power charging mode, and then the vehicle-mounted wireless charger is controlled to charge the mobile phone in a normal charging mode and a low-power charging mode in different time periods.
Specifically, charging may be controlled in a normal charging mode and a low power charging mode in different periods according to the remaining power of the cellular phone, and, for example, charging may be controlled in the normal charging mode for the first 1 hour of the current driving period and then charging may be controlled in the low power charging mode for 1 hour. The automatic distribution may be performed according to the remaining power of the mobile phone, or the charging power may be set according to the remaining power of the mobile phone and the current driving duration, which is not particularly limited herein.
