The invention relates to a distributed electric motor coach battery system and an electric motor coach, and belongs to the field of electric automobiles. The system comprises more than two battery subsystems which operate independently, each battery subsystem comprises a battery unit, a high-voltage distribution box and a sub-controller, and the high-voltage distribution box is provided with a battery interface connected with the battery unit, a charging interface connected with a charging module, and a power output interface connected with a motor controller; each sub-controller carries out charging scheduling on the battery unit of the sub-controller according to the electric quantity demand of the whole vehicle by combining the state of the battery unit of the corresponding battery subsystem; and according to the power requirement of the whole vehicle, power output scheduling is carried out on the battery unit of the battery subsystem by combining the battery unit state of the battery subsystem. Due to the fact that the battery subsystems only need to be connected with a part of high-voltage wire harnesses in the vehicle, the number of the high-voltage wire harnesses connected with the high-voltage junction boxes in the battery subsystems is relatively small, the battery subsystems are not connected with one another through the high-voltage wire harnesses, assembly is easier, and errors are not prone to occurring.

    本发明涉及一种分布式电动客车电池系统及电动客车,属于电动汽车领域。系统包括两个以上独立运行的电池子系统,每个电池子系统包括:电池单元,高压配电盒和子控制器,其中高压配电盒设置有:连接电池单元的电池接口,连接充电模块的充电接口;连接电机控制器的功率输出接口;子控制器根据整车电量需求,结合电池子系统的电池单元状态,对自身电池单元进行充电调度;根据整车动力需求,结合电池子系统的电池单元状态,对自身电池单元进行功率输出调度。由于各电池子系统仅需承担各自与车辆中一部分的高压线束连接,各电池子系统内部高压接线盒连接的高压线束相对较少,各电池子系统之间没有高压线束的连接关系,装配更容易,不容易出错。
