The invention provides a low-voltage power supply control system of an electric automobile, relates to the technical field of electric automobiles, and replaces an existing low-voltage storage battery to provide a low-voltage control power supply for the electric automobile. A low-voltage control power supply is provided for the electric vehicle by arranging a wake-up signal module (one or more combinations of a vehicle-mounted self-reset starting switch, a vehicle-mounted photovoltaic controller and vehicle-mounted charging equipment). According to different scenes, different modes are selected to replace an existing low-voltage storage battery to provide a low-voltage control power supply for the electric automobile, so that the cost and weight of the whole automobile are reduced, a power battery can be charged, and the driving range and economical efficiency of the automobile are improved.

    本发明提供了一种电动汽车的低压电源控制系统,涉及电动汽车技术领域,其取代现有的低压蓄电池,为电动汽车提供低压控制电源,在低压电源控制系统中,通过设置唤醒信号模块(车载自复位启动开关或者车载光伏控制器或者车载充电设备中的一种或多种组合)来为电动汽车提供低压控制电源。根据不同场景下选择不同的方式取代现有的低压蓄电池为电动汽车提供低压控制电源,从而降低整车成本和重量,还可以为动力电池充电,提高车辆的续驶里程和经济性。
