Technical Field

The invention belongs to the technical field of new energy automobiles, and particularly relates to a wireless charging method and a control system of a new energy automobile.

Background

With the increasing of automobiles, the air pollution is increasingly serious, the oil price is continuously increased, and in addition, the petroleum resource is a limited resource, so the development of the electric vehicle is very rapid. Nowadays, energy conservation and emission reduction and green and environment-friendly traffic concepts are provided at home and abroad, so that electric automobiles are rarely invested in huge research and development in all countries in the world. But the technical bottleneck restricting the development of the electric vehicle is that the manufacturing technology of the high-power storage battery is not broken through. The electric vehicle has the contradiction of small continuous running distance, troublesome charging, short service life of the battery and high price, which restricts the popularization of the electric vehicle. At present, the driving mileage of an electric vehicle is short, and the electric vehicle needs to go to a charging station for charging after driving for a certain distance, so that the popularization of the electric vehicle is greatly restricted. Electric vehicles are increasingly used. However, the charging of the electric vehicle is a problem which puzzles the public for a long time, although the number of the charging stations is increased, people can conveniently charge nearby, the charging time is still long due to the limitation of the battery technology, inconvenience is brought to electric vehicle owners, and the cost for building the charging stations is high.

Particularly, in recent years, the national government has made great support and subsidy on electric vehicles, and how to flexibly charge electric vehicles in real time to prolong the mileage of the electric vehicles becomes a technical problem to be solved urgently. In the prior art, known electrical equipment carries out electric energy transmission in a wired transmission mode (namely a mode of directly contacting a power supply), and due to the limitation of a power line, the electrical equipment is generally difficult to move, occupies a large space and affects the appearance, so that the electrical equipment is inconvenient to use.
