The invention provides a vehicle-mounted voltage control system and a control method thereof. The vehicle-mounted voltage control system comprises a battery pack, a power distribution part, a battery management part and a direct current conversion part. The power distribution part is electrically connected with the battery pack and the battery management part so as to change the communication relation between the power distribution part and the battery pack under the control of the battery management part, and the direct current conversion part is electrically connected with the battery management part and the power distribution part so as to assist the battery management part to realize closed-loop control on the battery pack. Therefore, the charging voltage and the output voltage of the battery pack are dynamically controlled, the flexibility of a battery pack grouping scheme is improved, and adaptable scenes are more diversified.

    本发明提供了车载电压控制系统及其控制方法。所述车载电压控制系统包括电池包、配电部、电池管理部和直流变换部。所述配电部电连接所述电池包和所述电池管理部,以在所述电池管理部的控制下改变与所述电池包之间的连通关系,所述直流变换部电连接所述电池管理部和所述配电部,以辅助所述电池管理部对所述电池包实现闭环控制,从而实现对电池包充电电压和输出电压的动态控制,有利于提升电池包成组方案的灵活性以及使可适配场景更加多样化。
