Electric vehicle charging method and device based on CP non-inductance, computer equipment and storage medium

The invention relates to an electric vehicle charging method and device based on CP non-inductance, computer equipment and a storage medium, and the method comprises the steps: obtaining a charging gun insertion signal, and receiving a starting mark instruction of an authentication protocol sent by a charging pile end; feeding back a response signal to the charging pile end according to a start flag instruction of the authentication protocol; judging whether the charging pile end receives a response signal or not; if so, sending the data packet to the vehicle end; the data packet is analyzed and verified, and if the data packet passes the verification, a response signal is sent to the charging pile end; judging whether the charging pile end receives a response signal or not; if yes, a PWM square wave signal is sent to a vehicle end, and the control switch is switched on, so that the CP wire reaches a set state; and after it is detected that the CP wire is in the set state, the relay is closed, and the vehicle
