The invention relates to a vehicle-mounted power supply assembly, a control method thereof and a computer readable storage medium. The vehicle-mounted power supply assembly comprises a vehicle-mounted charger module which is connected with a power grid of a charging pile and a power battery of a vehicle; a voltage transformation module which is connected with the output end of the vehicle-mounted charger module and a low-voltage storage battery of the vehicle; an auxiliary power supply which is connected with a power grid and is connected with power tubes of the vehicle-mounted charger module and the voltage transformation module; and a control chip, the power supply end of the control chip is connected with a control connecting line of the charging pile, and the control chip is configured to respond to the control pilot voltage of the charging pile and perform awakening through electric energy provided by the control pilot voltage; and sending a driving signal to the trigger switch to close a high-voltage switch of the charging pile. The power grid is connected to the on-board charger module and the auxiliary power supply in response to closing of the high-voltage switch. The auxiliary power supply is suitable for driving power tubes of the vehicle-mounted charger module and the voltage transformation module by using electric energy provided by a power grid, so that the low-voltage storage battery is charged by using the vehicle-mounted charger module and the voltage transformation module.

    本发明涉及一种车载电源总成及其控制方法,以及一种计算机可读存储介质。该车载电源总成包括:车载充电机模块,连接充电桩的电网及车辆的动力电池;变压模块,连接车载充电机模块的输出端及车辆的低压蓄电池;辅助电源,连接电网并连接车载充电机模块及变压模块的功率管;以及控制芯片,其供电端连接充电桩的控制连接线,并配置为:响应于充电桩的控制先导电压,利用控制先导电压提供的电能进行唤醒;并向触发开关发送驱动信号以闭合充电桩的高压开关。电网响应于高压开关的闭合而连接到车载充电机模块及辅助电源。辅助电源适于利用电网提供的电能来驱动车载充电机模块及变压模块的功率管,以利用车载充电机模块及变压模块来为低压蓄电池充电。
