The invention discloses a battery device for a vehicle, a power supply system and the vehicle. The battery device comprises a power battery and a first voltage conversion module, the first end of the first voltage conversion module is connected with the power battery, and the second end of the first voltage conversion module is used for being directly connected with a first load; the first voltage conversion module is configured to process the voltage output by the power battery in the parking state of the vehicle so as to supply power to the first load. The battery device can multiplex the power battery as the starting battery to process the voltage output by the power battery so as to supply power to the first load when the vehicle is in the parking state, and the power supply mode is simple, so that the power battery serves as an energy supply unit of the whole high-voltage power part, and the power supply efficiency is improved. And the power battery can be used as a starting battery to supply power to the first load, so that complete reuse of the power battery is realized, and the cost is greatly reduced.

    本申请公开了一种用于车辆的电池装置、供电系统及车辆,该电池装置包括动力电池和第一电压转换模块;所述第一电压转换模块的第一端与所述动力电池连接,所述第一电压转换模块的第二端用于直接连接第一负载;所述第一电压转换模块被配置为:在所述车辆的驻车状态,对所述动力电池输出的电压进行处理,以为所述第一负载供电。该电池装置能够在车辆的驻车状态下,将动力电池复用为启动电池,以对动力电池输出的电压进行处理,从而为第一负载供电,其供电方式简单,使得动力电池在作为整个高压动力部能量的提供单元的同时,又可以作为启动电池为第一负载供电,实现了动力电池的完全复用,极大地降低了成本。
