The invention relates to a reverse towing protection circuit of an electric automobile motor, in particular to an electric automobile reverse towing control circuit based on a motor controller. The electric automobile reverse-dragging control circuit based on the motor controller comprises a reverse-dragging switch, and a motor controller control panel and a key/start-stop button jointly act on the reverse-dragging switch. When the key is opened or the start-stop button is pressed down, the whole vehicle is started, the motor controller works, the reverse towing switch is closed, and the electric vehicle power system works normally. When the key is closed or the start-stop button is pressed down again, the whole vehicle stops, the motor controller is powered off, the reverse towing switchis switched off, namely, the motor controller and the driving motor wire harness are cut off, and the trailer can be safely towed. The invention provides a reverse towing protection circuit for an electric vehicle motor, which avoids secondary damage and other hidden dangers caused by a trailer and ensures the safety of people and vehicles.
本发明涉及电动汽车电机的反拖保护电路,具体为基于电机控制器的电动汽车反拖控制电路。基于电机控制器的电动汽车反拖控制电路包括反拖开关,电机控制器控制板与钥匙/启停按钮共同作用于反拖开关。当钥匙打开或启停按钮按下时,整车启动,电机控制器工作、反拖开关闭合,电动汽车动力系统正常工作。当钥匙关闭或启停按钮再次按下时,整车停机,电机控制器断电、反拖开关断开,即电机控制器与驱动电机线束切断,可以安全拖车。本发明提供了电动汽车电机用反拖保护电路,避免拖车带来的二次损坏和其他隐患,保证人车安全。
