Electromagnetic inductive type non-contact charging system and aligning method thereof

Abstract

The invention discloses an electromagnetic inductive type non-contact charging system and an aligning method thereof. The system comprises a ground electric energy emitting device and a vehicle-mounted electric energy receiving device, wherein the vehicle-mounted electric energy receiving device comprises a display module, a vehicle-mounted part controller, a vehicle-mounted wireless communication module, a vehicle-mounted electric energy receiving module, a battery and a vehicle-mounted receiving coil, and is arranged on a vehicle, the vehicle-mounted receiving coil is arranged below a chassis, the ground electric energy emitting device comprises a ground emitting coil, a ground electric energy emitting circuit, a driving module, a ground part controller and a ground wireless communication module, and is arranged on the ground, and the ground emitting coil is arranged on the top of the ground electric energy emitting device. On the basis of the traditional non-contact charging, a positioning aligning device taking the charging efficiency as the control target is added, so that an automatic optimizing function for the charging efficiency is realized; the system and the method are simple and easy to implement, and whether the current situation is suitable for charging or not can be judged only by monitoring the charging efficiency.

Description

technical field [0001] The invention belongs to the field of wireless charging and wireless positioning, and in particular relates to an electromagnetic induction non-contact charging device and an alignment method thereof. Background technique [0002] With the continuous development of electric vehicle technology and key component technology, vehicle electrification has become the development trend of the global automotive industry, and pure electric vehicles and other vehicles that are mainly driven by electric energy have become the main development trend in my country. [0003] For the promotion of pure electric vehicles, the supply and supplement of electric energy is an important factor, so the choice of battery charging method is extremely important. Contactless charging does not require connection devices such as power plugs, sockets, and wires. It transmits electrical energy through alternating electromagnetic fields or radio waves. Compared with traditional conta...

Problems solved by technology

However, the current wireless charging system does not consider the problem of position alignment. The charging system produced is very efficient in the laboratory, but in actual application, it is difficult to stop the vehicle to the specified range simply by relying on the driver's feeling. In this way, the charging efficiency is greatly reduced, resulting in a huge waste of electric energy and affecting the charging time
