The invention relates to a vehicle-mounted power supply control system, method and device, a vehicle and a storage medium. The vehicle-mounted power supply control system comprises a vehicle-mounted bidirectional OBC module, a vehicle-mounted DCDC module and a vehicle control unit. When the running state of the vehicle-mounted DCDC module and the running state of the current low-voltage power supply system of the whole vehicle are both normal, the vehicle-mounted DCDC module outputs first low-voltage direct current to charge the storage battery, and when the vehicle-mounted DCDC module is in a fault state or the low-voltage power supply system of the whole vehicle is abnormal, the vehicle-mounted bidirectional OBC module outputs second low-voltage direct current to charge the storage battery. The second low-voltage direct current function is enabled in time when the vehicle-mounted DCDC module breaks down or the low-voltage power supply network of the whole vehicle breaks down due to the fact that the first low-voltage direct current output is abnormal, so that normal low-voltage power utilization of the whole vehicle is guaranteed. The utilization rate of the vehicle-mounted bidirectional OBC module of the vehicle can be improved, the cost is low, and the arrangement space of the whole vehicle cannot be additionally occupied.
本发明涉及车载电源控制系统、方法、装置、车辆及存储介质,车载电源控制系统包括车载双向OBC模块、车载DCDC模块与整车控制器。在车载DCDC模块的运行状态及当前整车低压供电系统的运行状态均正常时,由车载DCDC模块输出第一低压直流电为蓄电池充电,当车载DCDC模块处于故障状态或整车低压供电系统异常时,则通过车载双向OBC模块输出第二低压直流电为蓄电池充电,以确保在车载DCDC模块出现故障或其第一低压直流电输出异常而导致整车低压供电网络瘫痪时及时启用第二低压直流电功能,以保障整车低压用电正常。本发明可以提高车辆的车载双向OBC模块的利用率,不仅成本较低,且不会额外占用整车布置空间。
