The invention relates to a compound control system with multiple battery packs connected in parallel for an industrial vehicle, which belongs to the technical field of battery management and comprises multiple groups of compound control units and a compound controller. The multiple groups of composite control units are arranged in parallel, each group of composite control units comprises a DCDC converter and a battery pack which are connected in series, and the DCDC converter is further connected with a charging device and an electricity load; according to the battery pack control method and device, the power output difference between the battery packs can be restrained, the problem that the performance of a whole power system of a vehicle is degraded due to the power output difference between the battery packs is solved, and therefore the service life of the battery packs is prolonged, and the service life of the battery packs is prolonged. The power supply cost of the vehicle is saved.

    本申请涉及一种工业车辆用多个电池组并联的复合控制系统,其属于电池管理技术领域,该控制系统包括多组复合控制单元和复合控制器;多组复合控制单元并联设置,多组复合控制单元中的每一组复合控制单元均包括互相串联的DCDC变换器和电池组,DCDC变换器还分别连接有充电装置和用电负载;复合控制器通过控制器局域网总线分别与每一组复合控制器中的DCDC变换器连接,本申请能够抑制电池组间的功率输出差异,降低因电池组间的功率输出差异带来的车辆整体动力系统性能衰减问题,从而提高电池组的使用寿命,节约车辆的电源成本。
