The invention relates to a vehicle-mounted charger control method and device, a medium, a vehicle-mounted charger and a vehicle. The method comprises the following steps: if a power-off instruction is received, controlling an auxiliary power supply of the vehicle-mounted charger to sleep; obtaining a CP signal output by the AC charging pile; generating an activation signal according to the state of the CP signal, and converting the activation signal from a low level to a high level only under the condition that the CP signal is converted from the low level to the high level and is converted into a PWM signal within a preset duration; and controlling the auxiliary power supply to be activated only under the condition that the activation signal is converted from the low level to the high level. Therefore, the defects that the vehicle-mounted charger cannot be dormant, other parts are activated and the storage battery is easily lack of electricity under the condition that some alternating current charging piles continuously send PWM signals outwards after charging is finished can be avoided, and the service life of the storage battery is prolonged.

    本公开涉及一种车载充电机的控制方法和装置、介质、车载充电机及车辆。方法包括:若接收到下电指令,控制所述车载充电机的辅助电源休眠;获取交流充电桩输出的CP信号;根据所述CP信号的状态生成激活信号,其中,仅在所述CP信号从低电平转换为高电平之后,又在预定时长之内转换为PWM信号的情况下,所述激活信号从低电平转换为高电平;仅在所述激活信号从低电平转换为高电平的情况下,控制激活所述辅助电源。如此,可以避免一些交流充电桩,在充电结束后会持续向外发送PWM信号的情况下,导致车载充电机无法休眠,从而激活其他零部件,容易导致蓄电池亏电的弊端,延长蓄电池的使用寿命。
