Abstract

The invention discloses a wireless charging method and system of an electric vehicle. The charging method comprises the following steps that firstly, preparatory work is conducted, wherein a wireless transmitting device is arranged on the ground of a parking area, electric vehicle guide rails are arranged on the two sides of the parking area and are each provided with a set of pressure sensor arrays, and a wireless receiving device is arranged on the bottom of the electric vehicle in a lifting mode through a lifting device; secondly, charging position alignment of the electric vehicle is conducted through the pressure sensor arrays; thirdly, the electric vehicle executes charging operation, wherein the wireless receiving device drives the lifting device to descend the wireless receiving device towards the wireless transmitting device to enable the wireless receiving device to get close to the wireless transmitting device, and energy transmission maximization is achieved.

Description

technical field [0001] The invention relates to the field of wireless charging for electric vehicles, in particular to a wireless charging method and charging system for electric vehicles. Background technique [0002] The charging method of electric vehicles is mainly wired charging, but the wired charging method has the following disadvantages: wired charging is time-consuming and laborious, it needs to connect wired cables, and wiring is troublesome. occur. Compared with the wired charging method, wireless transmission energy has attracted much attention due to its unique advantages. Wireless charging technology has solved many disadvantages of the wired charging interface to a certain extent, but the charging efficiency is far from that of wired charging. Currently, the existing The wireless charging device cannot judge and automatically adjust the position between the wireless transmitting device and the wireless receiving device, which reduces the charging efficiency....
