The invention discloses a power battery anti-theft circuit, a battery management system, a power battery and a vehicle, and the power battery anti-theft circuit comprises a vehicle ground potential interface, a first power interface, a current limiting assembly, a control module and a position information sending module; the first power interface is connected with the first input end of the control module and the first end of the current limiting assembly. The second end of the current limiting assembly is connected with the vehicle ground potential interface and the second input end of the control module. The vehicle ground potential interface is used for lowering the potential at the second input end of the control module when the vehicle ground potential interface is connected with a vehicle body; and the control module is used for sending the current position to a set user terminal through the position information sending module when the second input end of the control module receives the high level signal. By detecting the potential of the second end of the control module, whether the power battery is separated from the vehicle and stolen or not is judged, and after it is determined that the power battery is stolen, the position information is sent to a user so that the power battery can be found.

    本发明公开了一种动力电池防盗电路、电池管理系统、动力电池和车辆,其中,动力电池防盗电路包括:车辆地电位接口、第一电源接口、限流组件、控制模块和位置信息发送模块;第一电源接口分别与控制模块的第一输入端和限流组件的第一端连接;限流组件的第二端与车辆地电位接口和控制模块的第二输入端连接;车辆地电位接口用于在与车辆车身连接时,拉低控制模块第二输入端处的电位;控制模块用于在其第二输入端接收到高电平信号时,通过位置信息发送模块发送当前位置至设定用户终端。本发明通过检测控制模块第二端的电位,从而判断动力电池是否脱离车辆被盗窃,进而在确定被盗窃后,发送位置信息至用户,以便找回动力电池。
