Abstract

The invention relates to an electric vehicle charging plug supporting orderly charging and a method for realizing orderly charging. According to an electric vehicle charging plug of the present invention, it can receive three-phase line signals L1, L2, L3, neutral line signal N, protective earth signal PE, connection confirmation signal CC and control pilot signal CP provided by power supply equipment, And transmit the received L1, L2, L3, N, PE and CC signals to the vehicle socket through the electrical contacts, it is characterized in that the body of the electric vehicle charging plug also includes a logic adaptation circuit and a micro control unit, so The logic adaptation circuit is used to generate a CP replacement signal under the control of the micro control unit, and transmit the CP replacement signal to the vehicle socket instead of the CP signal in the energy transmission stage of the charging process of the electric vehicle, wherein In the energy transmission stage, the CP substitute signal is in the form of a pulse width modulation signal, and its duty cycle is independent of the duty cycle of the CP signal provided by the power supply device.

Description

technical field [0001] The present invention relates to an electric vehicle charging plug capable of supporting orderly charging and a method for realizing orderly charging, in particular to a method of charging through a built-in circuit of the charging plug without technical transformation of the AC charger (station). A scheme to adjust the charging current drawn by the on-board charger. Background technique [0002] Electric vehicles can be charged via external chargers (stations). Industry standards for electric vehicles, such as the current national standard GB / T 18487.01-2015, stipulate 4 charging modes and 3 connection methods for charging electric vehicles. Wherein, the charging mode 3 is applied to the situation that the power supply equipment connected to the AC grid connects the electric vehicle to the AC grid. The connection mode usually adopted for charging mode 3 is connection mode C (the cable assembly includes a charging cable permanently connected to a pow...
