The invention discloses a low-voltage power supply system with double DCDC and double storage batteries. According to the double-DCDC double-storage-battery looped network low-voltage power supply system, the two DCDCs and the two storage batteries are provided for an automatic driving vehicle, when the vehicle seriously breaks down in the automatic driving process and under the condition that any single power supply fails, the looped network power supply system can supply power to the vehicle, driving safety is guaranteed, and the service life of the vehicle is prolonged. Even under the condition that any two power supplies fail at the same time or any three power supplies fail at the same time, the low-voltage power supply system can still supply power to the vehicle, and safe parking of the vehicle is guaranteed.

    本申请公开了一种双DCDC双蓄电池的低压电源系统。根据本申请的双DCDC双蓄电池的环网低压电源系统为自动驾驶车辆提供了两个DCDC和两个蓄电池,当车辆在自动驾驶过程中严重故障时,任何单个电源失效的情况下,环网电源系统可以为车辆提供供电,保障行车安全,甚至在任何两个电源同时失效或者任何三个电源同时失效的情况下,该低压电源系统系统仍可以为车辆提供供电,保障车辆安全停车。
