According to the electric vehicle charging management system, the electric vehicle battery system and the automobile, auxiliary function current output by a charging pile serves as a triggering awakening signal of a battery management system BMS, and the auxiliary function current output by the charging pile does not serve as power supply current of the battery management system BMS; a good triggering effect brought by the unstable property of the auxiliary function current output by the charging pile can be utilized, so that the battery management system BMS in the dormant state is awakened, and the connection and pairing operation of the electric vehicle charging management system and the charging pile can be accurately identified; and on the other hand, negative effects such as damage or abnormal work of the BMS caused by unstable auxiliary function current can be avoided, the problems of unstable charging, charging failure or overcharging of the power battery pack of the electric vehicle are further avoided, and the charging stability and reliability of the electric vehicle are improved. The invention is widely applied to the technical field of automobiles.

    本发明公开了一种电动车充电管理系统、电动车电池系统和汽车,本发明以充电桩输出的辅助功能电流作为电池管理系统BMS的触发唤醒信号,而不将充电桩输出的辅助功能电流作为电池管理系统BMS的供电电流,可以利用充电桩输出的辅助功能电流所具有的不稳定性质带来的良好触发作用,从而唤醒处于休眠状态的电池管理系统BMS,能够准确识别电动车充电管理系统与充电桩的连接和配对操作;另一方面,本发明可以避免辅助功能电流不稳定对电池管理系统BMS造成损坏或者工作失常等负面影响,避免进一步引发电动汽车的动力电池包充电不稳、充电失败或者过充等问题,提高电动汽车的充电稳定性和可靠性。本发明广泛应用于汽车技术领域。
