Battery control system and method

Provided is a battery control system and method. A battery control system includes a plurality of battery packs and a controller. The battery packs are connected in parallel to each other, and the controller and the battery packs are connected to a controller area network (CAN) communication line. Each battery pack transmits/receives identifiers of the battery packs through the CAN communication line to/from each other. A master battery pack and slave battery packs are determined according to priorities of the identifiers. The controller communicates with the master battery pack, and the master battery pack communicates with the slave battery packs. 提供了电池控制系统和电池控制方法。所述电池控制系统包括多个电池包和控制器。所述多个电池包彼此并联地连接，所述控制器与所述多个电池包连接到控制器局域网路(CAN)通信线。每个电池包通过CAN通信线将所述多个电池包的标识符传输到彼此并从彼此接收所述多个电池包的标识符。根据标识符的优先级确定主电池包和从电池包。控制器与主电池包通信，主电池包与从电池包通信。
