Electric vehicle automatic identification system and method for alternating current charging pile

Abstract

The invention discloses an electric vehicle automatic identification system and method for an alternating current charging pile. The electric vehicle automatic identification system comprises a first communication device and a second communication device. The first communication device is installed on the charging pile. The second communication device is installed on an electric vehicle. A charging gun of the charging pile is simply inserted into the charging interface of the electric vehicle when needed, wherein the charging interface is an alternating current charging interface. The alternating current charging interface of the electric vehicle is used as a communication interface to communicate. The installation of a conductive wire is simpler. Moreover, the first communication device reads the identity information of the second communication device, which can automatically match to determine whether it can be charged and conduct automatic deduction. The charging process is simple, and the entire process is automatically completed, saving time and effort. There is no need to punch cards or scan a two-dimensional code through a phone to charge each time, which is convenient and quick. Users do not have to worry about charging inconvenience to individual charging or group charging due to the loss of charging cards.

Description

technical field [0001] The technical field of charging piles of the present invention, in particular, relates to an electric vehicle automatic identification system and method for AC charging piles. Background technique [0002] With the increasing use of automobiles, the impact of automobile exhaust on the environment is becoming more and more serious. In order to meet people's demand for automobiles and at the same time slow down the impact on the environment, the country currently advocates "energy saving and emission reduction". Electric vehicles are recommended. [0003] At present, whether it is a gasoline-electric hybrid electric vehicle or a pure electric vehicle, its most important energy comes from charging. At present, charging piles are used to charge electric vehicles at home and abroad, and domestic and foreign electric vehicles are equipped with electric vehicle charging piles. During the charging process, the interaction between the AC charging pile equipmen...

And by directly reading the BMS communication message data of the electric vehicle, analyzing the VIN code corresponding to the electric vehicle in the message, but because not all electric vehicle BMSs in the market have the vehicle VIN code, this method has certain limitations, which makes charging The user experience is very bad, and in the charging process of team-level or enterprise-level electric vehicle users, since the current charging pile equipment itself needs to swipe the charging card or charging password, the loss of the charging card and password will easily cause the team-level electric vehicle enterprise-level The user has serious financial problems in the process of charging management and financial settlement
