The invention discloses a low-voltage power supply system, a power supply management strategy and a vehicle. The low-voltage power supply system comprises a power battery, a voltage converter, a main storage battery, an auxiliary storage battery, a vehicle body controller, whole vehicle electric equipment and an on-off control assembly. The power battery is electrically connected with the main storage battery and the auxiliary storage battery at the same time through the voltage converter, the main storage battery is electrically connected with the vehicle body controller and the whole vehicle electric equipment at the same time, and the auxiliary storage battery is electrically connected with the vehicle body controller; the vehicle body controller can change the working state of the on-off control assembly. The power supply mode is flexible, power supply from the main storage battery to the whole vehicle electric equipment and the vehicle body controller can be stopped when the dormancy abnormal controller node exists, power supply from the auxiliary storage battery to the vehicle body controller can be reserved, and it is ensured that when the vehicle dormancy abnormal causes power shortage and the whole vehicle electric equipment is powered off, the vehicle body controller is powered off. And the vehicle body controller can normally receive a remote key signal.

    本发明公开了一种低压电源系统、电源管理策略以及车辆,所述低压电源系统包括动力电池、电压转换器、主蓄电池、副蓄电池、车身控制器、整车用电设备以及通断控制组件;所述动力电池通过所述电压转换器同时与所述主蓄电池、所述副蓄电池电连接,所述主蓄电池同时与所述车身控制器、所述整车用电设备电连接,所述副蓄电池与所述车身控制器电连接;所述车身控制器能够改变所述通断控制组件的工作状态。本发明的供电方式灵活,能够在存在休眠异常控制器节点时停止主蓄电池向整车用电设备以及车身控制器的供电,并且能够保留副蓄电池向车身控制器的供电,确保在车辆休眠异常导致亏电并对整车用电设备断电后,车身控制器能正常接收遥控钥匙信号。
