The invention relates to a vehicle power supply system and an automobile. The vehicle power supply system comprises a high-voltage power supply subsystem and a low-voltage power supply subsystem, wherein the low-voltage power supply subsystem comprises a high-low voltage conversion controller, a first low-voltage power supply module and a second low-voltage power supply module; the high-voltage power supply subsystem is used for sending a first electric signal so as to supply power to the driving motor and the low-voltage power supply subsystem; the high-low voltage conversion controller is used for receiving the first electric signal from the high-voltage power supply subsystem and converting the first electric signal into a second electric signal and a third electric signal; the first low-voltage power supply module is used for receiving the second electric signal from the high-low voltage conversion controller so as to supply power to the first load set; and the second low-voltage power supply module is used for receiving the third electric signal from the high-low voltage conversion controller so as to supply power to the second load set. The two low-voltage power supply modules providing different voltages are arranged to supply power to different load sets, so that the load bearing capacity of the vehicle can be improved, and the energy consumption of the vehicle is reduced.
本发明涉及一种车辆供电系统及汽车,包括高压供电子系统和低压供电子系统;其中,低压供电子系统中包括:高低压转换控制器、第一低压供电模块、以及第二低压供电模块;高压供电子系统,用于发送第一电信号,以向驱动电机和低压供电子系统供电;高低压转换控制器,用于从高压供电子系统接收第一电信号,并将第一电信号转换为第二电信号和第三电信号;第一低压供电模块,用于从高低压转换控制器接收第二电信号,以向第一负载集合供电;第二低压供电模块,用于从高低压转换控制器接收第三电信号,以向第二负载集合供电。本发明通过设置两个提供不同电压的低压供电模块,对不同的负载集合进行供电,可以提高车辆的负载承受能力、减小车辆的能耗。
