The invention belongs to the technical field of range extenders, and particularly relates to a vehicle low-voltage power supply system and a hybrid vehicle, the power supply system comprises a starting power supply used for being in power supply connection with a range extender and a direct current conversion module used for supplying power to a low-voltage load, and the direct current conversion module is further used for being in power supply connection with the range extender; the power supply system further comprises a decision control module, and the decision control module is used for enabling the direct current conversion module to be communicated with a power supply line of the range extender when the starting power supply fails, so that the direct current conversion module supplies power to the range extender, and starting of the range extender is guaranteed. Even in a severe environment, when a starting power supply fails, starting of the range extender can be guaranteed, and the endurance mileage of the vehicle is increased.

    本发明属于增程器技术领域,具体涉及一种车辆低压电源系统及混合动力车辆,电源系统包括用于供电连接增程器的启动电源和用于给低压负载供电的直流转换模块,所述直流转换模块还用于供电连接增程器,所述电源系统还包括决策控制模块,所述决策控制模块用于在启动电源故障时,使得直流转换模块与增程器的供电线路连通,以使直流转换模块给增程器供电,保障增程器启动。即使在恶劣环境中,启动电源故障时,也能保障增程器的启动,提升车辆续航里程。
