The invention relates to a vehicle power supply method, a power battery pack and a vehicle. The method comprises the following steps: acquiring current first voltage information of each battery cell in response to a received power supply request, outputting a first control instruction based on the first voltage information and a target voltage value in the power supply request, and indicating a single chip microcomputer to control the state of a corresponding relay, so that a plurality of battery cells form different series-parallel structures; the output voltage of the power battery pack for the whole vehicle component reaches the target voltage value; the single-chip microcomputer is indicated to control the state of the corresponding relay by outputting the corresponding instruction, so that the output voltage of the power battery pack is adjusted, the number of storage batteries does not need to be increased, electric energy is provided for whole vehicle parts, and the later maintenance cost is reduced while the vehicle weight is reduced.

    本发明涉及一种车辆供电方法、动力电池包和车辆。方法包括:通过响应于接收到供电请求,获取各电芯当前的第一电压信息,基于第一电压信息和供电请求中的目标电压值,输出第一控制指令,指示单片机控制对应的继电器的状态,使得多个电芯形成不同的串并联结构,直至动力电池包针对整车部件的输出电压达到目标电压值;本申请通过输出相应的指令,指示单片机控制对应的继电器的状态,以此调整动力电池包的输出电压,无需增加蓄电池的数量,为整车部件提供电能,减轻车辆重量的同时降低了后期维修成本。
