The invention discloses a battery system of a pure electric vehicle and a control method of the battery system. The control method comprises the steps that first battery parameter information from the battery system is received; a power supply and high-voltage loop conduction request corresponding to the first battery parameter information is sent to a vehicle control unit; a relay control instruction corresponding to the first battery parameter information and sent by the vehicle control unit is received, a relay corresponding to the relay control instruction is controlled to be closed, and high-voltage power-on of the battery system is completed; wherein all battery packs in the battery system are connected in parallel to form a multi-branch battery system. According to the invention, a user selects one or more battery packs to access the high-voltage main loop according to different transportation requirements, so that different mileage requirements are met, the selection flexibility is improved, the mileage anxiety of vehicle use is relieved, one vehicle has multiple purposes, the vehicle purchase cost and the vehicle use cost are greatly reduced, and meanwhile, the battery system has certain fault tolerance, so that the battery system is more convenient to use. And continuous operation of vehicles is ensured.

    本申请公开了一种纯电动车辆的电池系统及其控制方法,控制方法包括:接收来自电池系统的第一电池参数信息;向整车控制器发送与第一电池参数信息对应的供电和高压回路导通请求;接收整车控制器发送的与第一电池参数信息对应的继电器控制指令,并控制与继电器控制指令对应的继电器闭合,完成电池系统的高压上电;其中,电池系统中所有的电池组并联,形成多支路电池系统。本申请中,用户依据不同的运输需求选择一个或多个电池组接入高压主回路,以满足不同的里程需求,增加了选择灵活性,缓解了用车里程焦虑,同时实现一车多用,大大降低了购车成本和用车成本,同时电池系统具有一定的容错性,确保车辆持续运行。
