The invention provides a vehicle-mounted power supply device and an electric vehicle. The vehicle-mounted power supply device and the electric vehicle effectively solve the problems that a switching circuit in the vehicle-mounted power supply device is prone to damage and electric energy is wasted due to repeated conduction of the switching circuit. The vehicle-mounted power supply device comprises a first power conversion circuit and a switch module. The switch module comprises a driver, a switch assembly and a locking circuit. The first power conversion circuit is used for receiving the high-voltage direct current and outputting low-voltage direct current. The low-voltage load is used for receiving the low-voltage direct current or receiving the output voltage of the low-voltage power supply through the switch assembly. In the process that the low-voltage power supply supplies power to the low-voltage load through the switch assembly, the driver responds to a turn-off signal output by the locking circuit and controls the switch assembly to be used for disconnecting the low-voltage power supply and the low-voltage load until the locking circuit stops outputting the turn-off signal.

    本申请提供一种车载供电装置和电动汽车,有效的解决了车载供电装置中的开关电路反复导通所导致的开关电路易损坏以及电能浪费的问题。车载供电装置包括第一功率变换电路、开关模块。开关模块包括驱动器、开关组件以及锁死电路。第一功率变换电路用于接收高压直流电并输出低压直流电。低压负载用于通过开关组件接收低压直流电或接收低压电源的输出电压。在低压电源通过开关组件向低压负载供电的过程中,驱动器响应于锁死电路输出的关断信号,控制开关组件用于断开低压电源和低压负载之间的连接直到锁死电路停止输出所述关断信号。
