The invention relates to a whole vehicle power supply system, a vehicle and a whole vehicle power supply method. The whole vehicle power supply system comprises a first power supply assembly. The second power supply assembly is connected in series with the first power supply assembly; the first switch assembly is connected with the first power supply assembly and the second power supply assembly. The second switch assembly is connected with the first power supply assembly and the second power supply assembly. The first low-voltage load group is connected with the second end of the first switch assembly and used for receiving power supplied by the first power supply assembly and the second power supply assembly under the condition that the first switch assembly is switched on, and the first switch assembly is kept in a switched-on state when the vehicle is powered off; the second low-voltage load group is connected with the second end of the second switch assembly and used for receiving power supplied by the first power supply assembly and the second power supply assembly under the condition that the second switch assembly is switched on, and the second switch assembly is kept in a switched-off state when the vehicle is powered off. The whole vehicle power supply system can avoid the power shortage condition of the vehicle.
本申请涉及一种整车供电系统、车辆和整车供电方法。整车供电系统包括第一供电组件;第二供电组件与第一供电组件串联连接;第一开关组件分别与第一供电组件、第二供电组件连接;第二开关组件分别与第一供电组件、第二供电组件连接;第一低压负载群与第一开关组件的第二端连接,用于在第一开关组件导通的情况下,接收第一供电组件和第二供电组件的供电,第一开关组件在车辆下电时保持导通状态;第二低压负载群与第二开关组件的第二端连接,用于在第二开关组件导通的情况下,接收第一供电组件和第二供电组件的供电,第二开关组件在车辆下电时保持断开状态。本申请的整车供电系统可以避免车辆出现亏电情况。
