The invention discloses a vehicle power supply system and method and a vehicle. The system comprises a fuel cell, a power cell, a first converter and a second converter, and the fuel cell is connected with the first converter; the power battery is connected to the voltage distribution module through a first switch element, and the power battery is electrically connected with the first converter through the first switch element; the power battery is connected with the second converter through a second switch element; the first converter and the second converter are electrically connected, and the first converter and the second converter are both connected to the voltage power distribution module to supply power to target equipment connected with the voltage power distribution module. The technical problem that the cost of the whole vehicle is high due to the fact that a low-voltage power battery possibly cannot be matched with the voltage value output by a fuel cell after boosting, and a high-voltage platform is mostly adopted for vehicle power supply at present is solved.

本申请公开了一种车辆供电系统、方法和车辆。其中，该系统包括：燃料电池、动力电池、第一转换器和第二转换器，其中，燃料电池，与第一转换器连接；动力电池，通过第一开关元件连接至电压配电模块，且动力电池通过第一开关元件与第一转换器电性连接；动力电池，通过第二开关元件与第二转换器连接；第一转换器和第二转换器之间电性连接，且第一转换器和第二转换器均连接至电压配电模块，以为与电压配电模块连接的目标设备供电。本申请解决了由于采用较低电压的动力电池可能无法匹配燃料电池在升压后所输出的电压值，导致目前车辆供电多采用高压平台，造成的整车成本较高的的技术问题。
