A vehicle-mounted power supply device is used for providing a first output voltage and a second output voltage for redundant backup. The vehicle-mounted power supply device is used for outputting first output voltage to the two first loads of the redundant backup through the two first load interfaces of the redundant backup and outputting second output voltage to the two second loads of the redundant backup through the two second load interfaces of the redundant backup, and the first loads and the second loads are different in function. The vehicle-mounted power supply device is used for receiving power supplied by a vehicle-mounted battery through the vehicle-mounted battery interface and receiving power supplied by a power battery through the power battery interface, and the output voltage of the power battery is larger than the first output voltage and the second output voltage. The vehicle-mounted power supply device is used for receiving power supplied by one of the vehicle-mounted battery and the power battery and outputting a first output voltage through any first load interface and outputting a second output voltage through any second load interface. The power assembly and the vehicle can be designed based on the vehicle-mounted power supply device.

    一种车载供电装置用于提供冗余备份的第一输出电压和第二输出电压。车载供电装置通过冗余备份的两个第一负载接口分别用于向冗余备份的两个第一负载输出第一输出电压,通过冗余备份的两个第二负载接口分别用于向冗余备份的两个第二负载输出第二输出电压,第一负载与第二负载的功能不同。车载供电装置通过车载电池接口用于接收车载电池的供电,通过动力电池接口用于接收动力电池的供电,动力电池的输出电压大于第一输出电压和第二输出电压。车载供电装置用于接收车载电池和动力电池中其中一个的供电并分别通过任一个第一负载接口输出第一输出电压和任一个第二负载接口输出第二输出电压。一种动力总成以及车辆可以基于该车载供电装置来设计。
