A wireless charging system and method for electric vehicles with storage and deviation correction functions

Abstract

The invention discloses an electric car wireless charging system and method with storage and deviation rectification functions. The system comprises an underground pit layer, a parallel connection mechanism, a storage covering device, a ground layer, a primary coil, a secondary coil and an electric vehicle. The parallel connection mechanism is fixed to the underground pit layer, and the primary coil is placed above the parallel connection mechanism. The storage covering device is parallel to the ground and can move horizontally, and a wireless charging emission outlet can be opened and closed.The secondary coil is fixed to the lower side behind the electric vehicle. When an automobile is parked above the charging device, the storage covering device is turned on, and the primary coil is automatically aligned to the secondary coil under the effect of the parallel connection effect. When charging is completed, the primary coil is stored under the ground under the effect of the parallel connection effect, and the emission outlet is closed by the storage covering device. Storage and deviation rectification of the wireless charging process of the electric vehicle can be achieved, the electric vehicle wireless charging efficiency is effectively improved, and the charging process is more convenient.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a wireless charging system and method for electric vehicles with storage and deviation correction functions. Background technique [0002] Air pollution represented by smog is becoming more and more serious. As an important source of air pollution, the exhaust emission of fuel vehicles is a technical problem that needs to be solved urgently. Electric vehicles do not need to consume fuel, can achieve zero emissions, and can effectively reduce the source of air pollution, which is an inevitable trend in the future development of automobiles. At present, electric vehicles are limited by battery technology, and the mileage of electric vehicles is often not large, and frequent charging is often required. The charging process of traditional wired charging technology often needs to drag the cable, and the charging socket is very easy to generate electric sparks, a...

Problems solved by technology

However, in actual use, when an electric vehicle is directly docked for charging, affected by factors such as vehicle load and docking deviation, there are often azimuth and angle deviations between the primary and secondary coils, making the air gap between the two sides often Unable to reach preset value

In reality, the electrical components in the electric vehicle charging system are often unable to be replaced in real time, which not only greatly reduces the efficiency of wireless charging for electric vehicles, but also gradually highlights safety issues such as heat generation and leakage during the charging process.
