The invention discloses a working method of a vehicle-mounted battery pack, a vehicle-mounted battery and an electric vehicle. The working method is applied to a first processor in a main battery pack in the vehicle-mounted battery pack. The vehicle-mounted battery is divided into the master battery pack and the slave battery pack, so that the weight and the size of a single battery pack are reduced while normal discharge of the electric vehicle is ensured, and the vehicle-mounted battery is easy to move and disassemble. Meanwhile, the voltage of the main battery pack and the voltage of the slave battery pack are obtained, and the working state of the vehicle-mounted battery is determined. According to the voltage difference between the two battery packs and the working state of the vehicle-mounted battery, it is judged that the main battery pack and the slave battery pack work together, the main battery pack works independently and the slave battery pack works independently, and the situation that the service life of the battery is shortened due to the fact that the high-voltage battery pack charges the low-voltage battery pack is prevented.

    本发明公开了一种车载电池包的工作方法、车载电池及电动车,应用于车载电池包中的主电池包中的第一处理器。将车载电池分为主电池包及从电池包,在保证为电动车正常放电的同时,减轻了单个电池包的重量和体积,易于移动以及拆卸。同时,获取主电池包的电压以及从电池包的电压,确定车载电池的工作状态。根据两个电池包的电压差以及车载电池的工作状态判定主电池包及从电池包共同工作、主电池包单独工作及从电池包单独工作,防止高电压的电池包为低电压的电池包充电,使得电池的寿命降低。
