An in-vehicle power supply system includes: a main battery; an upper power supply unit configured to supply power supply power to the main battery; a first power line distributed to conduct power supply power of a first voltage; a second power line distributed to conduct power supply power of a second voltage lower than the first voltage; a step-down conversion unit configured to step down a voltage of the first power supply line to supply power supply power to the second power supply line; and a capacitor. The input of the step-down conversion unit, the upper power supply unit, and the capacitor are connected to the first power supply line. The output of the step-down conversion unit and the main battery are connected to a second power supply line.
一种车载电源供给系统,包括:主电池;上位电源单元,其被配置为向主电池供应电源电力;第一电源线,其被分配为传导第一电压的电源电力;第二电源线,被分配为传导低于第一电压的第二电压的电源电力;降压转换单元,其被配置为使第一电源线的电压降压,以向第二电源线供应电源电力;以及电容器。降压转换单元的输入、上位电源单元以及电容器连接到第一电源线。降压转换单元的输出和主电池连接到第二电源线。
