Charging pile based on random code decoding and charging vehicle identity verification method

Abstract

The invention discloses a charging pile and charging vehicle identity verification method based on random code decoding, and the method comprises the steps: binding a charging pile and a vehicle through a management system, setting a charging password in the management system, transmitting the password, and writing the password into the corresponding charging pile and vehicle; when the charging gun is connected with a charging socket of a vehicle, enabling the charging pile to generate an original random code, encrypting the original random code through a charging password, filling the encrypted random code in a reserved position of a charging protocol, and sending the charging protocol filled with the random code to a battery management system of the vehicle; enabling the battery management system to decrypt the random code according to a preset charging password and send a decryption result to the charging pile; and enabling the charging pile to compare the decryption result with anoriginal random code generated by the charging pile: if the decryption result is consistent with the original random code, passing the verification, and performing charging, and if not, determining that the verification is not passed and charging is not performed. The charging pile is safe and reliable, plug-and-play charging can be achieved, and manual operation is not needed.

Description

technical field [0001] The invention relates to a method for verifying the identity of a charging pile and a charging vehicle based on random code decoding, and belongs to the technical field of new energy electric vehicle charging. Background technique [0002] Private charging piles require identity verification when the vehicle is connected to prevent non-owner vehicles from occupying the charging pile. The identification functions adopted by existing charging piles include the following types, Bluetooth authentication, card swiping authentication and wireless communication authentication. These authentication methods have the defects that the authentication process takes too long and the user operation is cumbersome. Bluetooth authentication requires the user to turn on the Bluetooth device, search and connect, and the Bluetooth transmission distance is relatively short, and the matching speed is slow; the card swiping operation is relatively primitive, and there is sti...
