The invention discloses a BMS control circuit, a battery management system and an electric vehicle. The control circuit of the BMS comprises a charging and discharging switch module, a follow current module and a control module, the charging and discharging switch module is used for being connected between a battery and a load. The freewheeling module is connected in parallel with a load; the control module is respectively connected with the charging and discharging switch module and the follow current module, and the control module is used for generating a first control signal and a second control signal; the charging and discharging switch module is used for being turned off in response to the first control signal; and the follow current module is started in response to the second control signal when the charging and discharging switch module is switched off. According to the technical scheme provided by the embodiment of the invention, the problem that devices are easy to damage due to impact current generated when charging and discharging of the electric vehicle are suddenly stopped is solved.

    本发明公开一种BMS的控制电路、电池管理系统及电动车辆。该BMS的控制电路,包括充放电开关模块、续流模块和控制模块;充放电开关模块用于连接于电池与负载之间;续流模块用于与负载并联连接;控制模块分别与充放电开关模块和续流模块连接,控制模块用于生成第一控制信号和第二控制信号;充放电开关模块用于响应于第一控制信号关断;续流模块用于在充放电开关模块关断时,响应于第二控制信号启动。本发明实施例提供的技术方案解决了电动车辆在充放电突然停止时所产生的冲击电流容易造成器件毁坏的问题。
