The invention relates to the technical field of electric vehicle charging, in particular to a CP signal generation circuit for new energy vehicle charging, which comprises a main control module, an interlocking module I, an interlocking module II, an isolation module, a resistance module, a power supply module and a signal output module, and is characterized in that the output end of the main control module is electrically connected with the input end of the interlocking switch module I; the output end of the first interlocking switch is electrically connected with the input end of the isolation module and the input end of the second interlocking switch. Compared with a common CP generation circuit in the market at present, only one resistor with the resistance value of 1K is adopted in the circuit, so that in actual use, the temperature of the resistor in the circuit is greatly reduced, the overall temperature rise of the circuit is better, the loss of the circuit is reduced, the energy consumption of the circuit is lower, and the service life of the circuit is prolonged. And the voltage loss of a diode or an optocoupler triode in a passive device is reduced, so that the voltage accuracy is higher and is not influenced by the turn-on integrity of the triode.

    本发明涉及电动汽车充电技术领域,具体为一种新能源汽车充电用CP信号发生电路,包括主控制模块、互锁模块一、互锁模块二、隔离模块、电阻模块、电源模块和信号输出模块,所述主控制模块的输出端与所述互锁开关模块一的输入端电性连接,所述互锁开关一的输出端与所述隔离模块和所述互锁开关二的输入端电性连接。本发明相较于现在市面常见的CP发生线路,本申请的线路中只采用了一个1K阻值的电阻,这样在实际使用中,线路中电阻的温度会大大降低,进而会使得线路整体温升更好,降低线路的损耗,使得线路的能耗更低,减少的被动器件的中二极管或者光耦三极管的电压损耗,使得电压准确度更高,不受三极管开通完整性影响。
