The invention discloses an electric vehicle battery pack unit damage detection and control circuit, which comprises a battery pack, an electric control charging module, a battery detection and control module and an alarm display module, and is characterized in that a positive electrode and a negative electrode of the battery pack are respectively connected with the battery detection and control module through wires to form a loop; according to the invention, the diode is arranged, so that the voltage and current of the healthy battery pack cannot charge the damaged battery pack, the voltage of the damaged battery pack cannot be increased, and the detection result cannot be influenced, and the output of the damaged battery pack is cut off through the switch. Heating and damage aggravation caused by overdischarge of the damaged battery pack can be prevented; and by arranging the temperature detector, when the temperature of one part rises to a dangerous value, the switch circuit can be switched off.
本发明公开了一种电动汽车电池组单元损坏检测及管控电路,包括电池组、电控充电模块、电池检测及控制模块、报警显示模块,所述电池组正极、负极分别通过导线与电池检测及控制模块连接组成回路,同时通过另一导线与电控充电模块、驱动电机连接组成回路,本发明通过设置二极管,使健康组电池的电压电流对损坏组无法充电,也不能拉高损坏组电池的电压从而影响检测结果,同时通过开关切断损坏组电池的输出,可以防止损坏的电池组过度放电导致发热和损坏加剧;通过设置温度检测器,当有一处温度升高到危险值时,也可以让开关电路动作断开。
