Electric car charging control method and system

Abstract

The invention relates to an electric car charging control method and system. The electric car charging control method comprises the following steps of firstly, mainly utilizing a radio frequency cardreader to read vehicle electronic tag information, wherein the electronic tag information comprises vehicle information and the configuration information of short distance wireless communication; according to the obtained configuration information of the short distance wireless communication, establishing short distance wireless communication connection between a vehicle end and a charging pile end, sending the collected position information of a pantograph and the collected position information of a charging bow to the vehicle end to enable the vehicle to finish parking to a proper position;and after the vehicle finishes parking to the proper position, establishing the wireless network interaction charging relevant information of the vehicle end and the charging pile end, driving the charging bow to move to a position adaptive to the pantograph, and beginning to charge. The electric car charging control method adopts a composite communication means of "RFID (Radio Frequency Identification) + micropower communication + WiFi", automatic connection of communication between the vehicle end and the charging pile end is realized, and one-to-one charging of the pantograph and the charging bow of the vehicle can be quickly and accurately realized.

Description

technical field [0001] The invention is applicable to the field of electric bus pantograph charging, and in particular relates to an electric vehicle charging control method and system. Background technique [0002] Existing electric buses mostly use a push-down charging bow for charging. The push-down charging bow is usually set above the platform, and the pantograph is set on the top of the electric bus. When it is necessary to charge the electric bus, the bus drives to the bottom of the charging bow, the charging bow stretches downwards, and starts charging after it is normally overlapped with the pantograph on the roof. [0003] However, in the charging technology of the push-down charging bow, there are problems: the charging preparation time is long, and the charging positioning is not accurate enough. The long charging preparation time is specifically reflected in the long time spent on vehicle location positioning and data interaction, which leads to long charging ...
