The invention relates to an electric vehicle charging plug supporting ordered charging and a method for realizing ordered charging. The electric vehicle charging plug in the present invention can receive three-phase line signals L1, L2, L3, a zero line signal N, a protective ground signal PE, a connection confirmation signal CC, and a control guide signal CP provided by a power supply device, andthe received L1, L2, L3, N, PE, and CC signals are transmitted to a vehicle socket through an electrical contact. The electric vehicle charging plug is characterized in that a logic adaptation circuitand a micro-control unit are further arranged in the body of the electric vehicle charging plug; the logic adaptation circuit is used for generating a CP replacement signal under the control of the micro-control unit, and the CP replacement signal is used for replacing the CP signal and transmitted to the vehicle socket in the energy transmission stage of the electric vehicle charging process; and in the energy transmission stage, the CP replacement signal is in the form of a pulse width modulation signal, and the duty ratio of the CP replacement signal is independent of the duty ratio of theCP signal provided by the power supply equipment.
本发明涉及一种支持有序充电的电动汽车充电插头及实现有序充电的方法。根据本发明的一种电动汽车充电插头,其能够接收由供电设备提供的三相线信号L1、L2、L3,零线信号N、保护接地信号PE、连接确认信号CC以及控制导引信号CP,并通过电触头向车辆插座传递所接收的L1、L2、L3、N、PE和CC信号,其特征在于,所述电动汽车充电插头的本体内还包括逻辑适配电路以及微控制单元,所述逻辑适配电路用于在所述微控制单元的控制下生成CP替代信号,并在电动汽车充电进程的能量传输阶段以所述CP替代信号来代替所述CP信号传递给车辆插座,其中在能量传输阶段,所述CP替代信号的形式为脉宽调制信号,且其占空比独立于由供电设备提供的CP信号的占空比。
