Electric vehicle automatic charging method and system

Abstract

The invention provides an electric vehicle automatic charging method and system . The method comprises the following steps: the charging equipment receives a charging request message including vehiclemodel information sent by the electric vehicle, obtains the height from an electric vehicle power receiving interface to the ground according to the vehicle model information, and adjusts the position of a charging plug in the height direction, so that the height from the charging plug to the ground is the same as the height from the electric vehicle power receiving interface to the ground; the charging equipment moves in a first horizontal direction drives a laser source to emit a line laser signal to the electric vehicle in the moving process, obtains the position coordinates of the electric vehicle power receiving interface in the first horizontal direction and the second horizontal direction through laser ranging scanning, then adjusts the position of the charging plug on the horizontal plane according to the position coordinates of the power receiving interface in the first horizontal direction and the second horizontal direction, and completes butt joint of the charging plug andthe electric vehicle power receiving interface. According to the scheme, the recognition speed of the electric vehicle power receiving interface is high, and the electric vehicle charging efficiencycan be improved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to an automatic charging method and system for electric vehicles. Background technique [0002] At present, electric vehicle technology has been developed rapidly, and the application fields of electric vehicles are becoming more and more extensive, and the number of applications is also increasing. Therefore, the charging efficiency of electric vehicles is very important. [0003] In the prior art, visual sensors are usually used to locate and identify the charging interface of the electric vehicle, but the recognition speed is slow, resulting in low charging efficiency of the electric vehicle. Contents of the invention [0004] Aiming at the above-mentioned problems in the prior art, the present invention provides an electric vehicle automatic charging method and system. [0005] In a first aspect, an embodiment of the present invention provides an automatic charging method fo...
