Intelligent charging access system for electric automobile

Abstract

The invention discloses an intelligent charging access system for an electric automobile. The intelligent charging access system for the electric automobile comprises an intelligent charging leading system and a vehicle certification system based on a wireless communication network. The intelligent charging leading system comprises a central server, a mobile communication network, the Internet, a charging station end data collecting system and a vehicle-mounted information collecting terminal. The intelligent charging access system can provide accurate charging station distribution information for a user, and the user is led to be access to a specific charging pile in a charging station to be charged according to the vehicle information of the user. The central server can accept inquiry of various modes from a user end and combine with the battery parameter of the automobile and the preferences or requirement of the user to make a reasonable charging planning and decision scheme. The vehicle certification system is used for achieving identity certification and the payment condition of legal users, so that the fact that illegal automobiles occupy limited charging resources (such as charging files and electricity) is avoided, and the privacy of the user and the safety of data are protected.

Description

technical field [0001] The invention relates to an electric vehicle intelligent charging device, in particular to an electric vehicle intelligent charging access system. Background technique [0002] The promotion of electric vehicles is of great help to solve energy and environmental problems. The promotion of electric vehicles requires the support of sound infrastructure, especially the support of intelligent charging systems, otherwise electric vehicles will be difficult to implement due to battery charging problems that cannot meet the needs of users. The research on the key technology of electric vehicle infrastructure at home and abroad is mainly carried out around the intelligent charging station. For example, IBM Corporation, Honda Corporation, and PE&G Corporation have carried out a joint experimental project on the intelligent charging system of electric vehicles, and achieved remarkable results. Other related research also focuses on how to use ICT technology to...
