Abstract

The invention provides a charging method, system and charging device for an electric vehicle. The charging method comprises the following steps that the to-be-charged electric vehicle is identified bythe charging device; and when the electric vehicle is charged, the charging device obtains charging information of the electric vehicle from a vehicle server of the electric vehicle through a charging device server, so that direct communication between the electric vehicle and the charging device is avoided, and meanwhile, the charging information of the electric vehicle is obtained by the charging device.

Description

technical field [0001] The invention relates to the technical field of vehicle charging, in particular to an electric vehicle charging method, system and charging equipment. Background technique [0002] When charging equipment such as charging piles is charging electric vehicles, in order to facilitate users to know relevant charging information such as the remaining charging time in a timely manner, the charging equipment often monitors the relevant data of the electric vehicle power battery to calculate and display the remaining charging time. [0003] In the prior art, in order to obtain relevant charging information, the charging device needs to communicate with the electric vehicle. During DC charging, the charging device communicates with the electric vehicle through a Controller Area Network (CAN) bus to obtain charging information. During AC charging, there is no CAN bus on the AC charging equipment, and the CAN bus cannot be used to communicate with the electric v...
