The invention discloses a battery management system for an electric vehicle and the electric vehicle. The battery management system comprises a battery control unit and a battery cell control unit. Wherein the battery control unit is arranged in a low-voltage area of the electric automobile, the battery cell control unit is arranged in a high-voltage area of the electric automobile, an isolation area is arranged between the high-voltage area and the low-voltage area, and the battery control unit and the battery cell control unit respectively comprise a low-voltage wireless communication module and a high-voltage wireless communication module for data communication between the battery control unit and the cell control unit. As the high-voltage area and the low-voltage area are not connected with the wire harness, the high-voltage wire harness bridged between the high-voltage area and the low-voltage area does not need to be insulated, so that the wiring of the whole electric automobile is simplified, the cost is saved, and the insulation fault caused by the damage of the insulating layer of the bridged wire harness in the high-voltage area and the low-voltage area is reduced; and meanwhile, the probability that electronic parts in a low-voltage area are damaged due to the damage of the insulating layer of the jumper wire harness is reduced.

    本申请公开了一种用于电动汽车的电池管理系统和电动汽车,包括电池控制单元和电芯控制单元。其中,电池控制单元设置在电动汽车的低压区域,电芯控制单元设置在电动汽车的高压区域,高压区域与所述低压区域之间设置有隔离区域,电池控制单元和电芯控制单元分别包括低压无线通讯模块和高压无线通讯模块,以用于电池控制单元和电芯控制单元的数据通讯。由于高压区域与低压区域不存在线束连接,不需要对跨接在高压区域与低压区域间的高压线束做绝缘处理,使得电动汽车整车布线得到简化,节约成本,减少高低压区域的跨接线束绝缘层损坏引起的绝缘故障,同时降低了低压区域电子零部件因跨接线束绝缘层损坏而引起损坏的概率。
