The invention provides a vehicle-mounted charger, a power battery heating method and system and an automobile, the power battery is heated by introducing alternating current of an alternating current charging pile into a heating structure of the power battery through the vehicle-mounted charger, and meanwhile, the vehicle-mounted charger converts 220V alternating current into 12V direct current to supply power to a low-voltage battery, so that the power battery is heated. And low-voltage energy required by the work of each controller in the awakening state during the heating period of the power battery is provided, so that the energy consumption of the power battery and the low-voltage battery in a charging heating scene is avoided.

    本发明提供一种车载充电机、动力电池加热方法、系统及汽车,通过利用交流充电桩的交流电流经车载充电机引入到动力电池的加热结构,给动力电池加热,同时车载充电机将220V交流电转换为12V直流电给低压电池补电,提供动力电池加热期间处于唤醒状态的各控制器工作所需的低压能量,避免在充电加热场景下造成动力电池和低压电池的本身能量消耗。
