The invention provides a double-battery-pack battery system control strategy which comprises a battery system working mode recognition method, a power-on control method, a battery pack normal power-off control method and a fault power-off control method, and the power-on control method comprises a single-pack high-voltage control method and a double-pack high-voltage control method. The battery pack normal power-off control method comprises a single-pack normal power-off control method and a double-pack normal power-off control method, and the fault power-off control method comprises a single-pack fault power-off control method and a double-pack fault power-off control method. The two battery packs are independently controlled by the two battery management systems respectively, so that when one battery pack of the vehicle breaks down and needs to be maintained, the other battery pack can be used for achieving single-pack operation, and therefore different use requirements can be well met.

    本发明提供了一种双电池包电池系统控制策略,其包括电池系统工作模式识别方法、上电控制方法、电池包正常下电控制方法和故障下电控制方法,其中上电控制方法包括单包上高压控制方法和双包上高压控制方法,电池包正常下电控制方法包括单包正常下电控制方法和双包正常下电控制方法,故障下电控制方法包括单包故障下电控制方法和双包故障下电控制方法。本发明的两个电池包分别由两个电池管理系统独立控制,使得车辆在其中一个电池包有故障需维修期间,能够利用另一个电池包实现单包运营,从而能够较好地满足不同的使用需求。
