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 first converter is electrically connected with the fuel cell and used for converting direct current with a first voltage value output by the fuel cell into direct current with a second voltage value; the second converter is electrically connected with the power battery and used for converting the direct current of the third voltage value output by the power battery into the direct current of the fourth voltage value or converting the direct current of the fourth voltage value input to the power battery into the direct current of the third voltage value, and the first converter is electrically connected with the second converter; and the first converter and the second converter are connected to the voltage 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,第一转换器,与燃料电池电性连接,用于将燃料电池输出的第一电压值的直流电转换为第二电压值的直流电;第二转换器,与动力电池电性连接,用于将动力电池输出的第三电压值的直流电转换为第四电压值的直流电,或者将向动力电池输入的第四电压值的直流电转换为第三电压值的直流电,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。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。
