The invention discloses a wake-up and sleep circuit of an alternating current charging CP signal. The circuit is characterized by comprising a 5V constant power module, a CP signal conversion module,a D trigger module, a D latch module, a BMS main control chip, a selection switch module and a power supply module, and the 5V constant power module is connected with the CP signal conversion module,the D trigger module and the D latch module; the CP signal conversion module is sequentially connected with the D trigger module, the D latch module, the selection switch module and the power supply module; the BMS main control chip is connected with the D trigger module, the D latch module, the selection switch module and the power supply module. With logic combination control of high and low level changes of input and output signals of the D flip-flop and the D latch, the functions of automatically awakening the BMS and enabling the BMS to automatically sleep of the AC charging CP signal arerealized, and the circuit has important production practice significance.

    本发明公开了一种交流充电CP信号的唤醒和休眠电路,其特征在于,包括5V常电模块、CP信号转换模块、D触发器模块、D锁存器模块、BMS主控芯片、选择开关模块和电源模,其中:5V常电模块,分别与CP信号转换模块、D触发器模块和D锁存器模块相连接;CP信号转换模块依次与D触发器模块、D锁存器模块、选择开关模块和电源模块;BMS主控芯片分别与D触发器模块、D锁存器模块、选择开关模块和电源模块相连接,本发明通过对D触发器和D锁存器的输入输出信号高低电平变化的逻辑组合控制,来实现交流充电CP信号自动唤醒BMS以及使BMS自动休眠的功能,具有重大的生产实践意义。
