Abstract

The invention relates to a non-contact movable intelligent charging method for an electric vehicle and a system thereof. The system is characterized by comprising a charging post and a vehicle-mounted charging terminal, and duplexing communication is realized between the charging post and the vehicle-mounted charging terminal by a 2-27MHz shortwave communication mode. The invention has the following beneficial effects that the system can charge electric vehicles in normal running in a non-contact mode so as to finish charging for the electric vehicles in the running process, avoid the limitation that the electric vehicles need to be stopped for charging, indirectly solve the problems of limited endurance capability of rechargeable batteries and longer charging time, effectively solve the problems of charging distance, charging efficiency and the like by calculating and adjusting the transmitting frequency of a magnetic resonance charging circuit in real time, completely realize intellectualization in the charging process, and have practicability and safety as well as efficiency and energy conservation.

Description

technical field

[0001] The invention relates to a non-contact charging method and system thereof, in particular to a non-contact mobile intelligent charging method and system thereof for electric vehicles. Background technique

[0002] As a new type of transportation, electric vehicles have the advantages of zero emissions and wide energy sources. They are considered to be an important means to alleviate the shortage of China's oil resources and solve the problem of urban air pollution. However, the technical research on electric energy supply, conversion and transmission of electric vehicles is progressing slowly. On the other hand, in June 2007, the research team of MIT researcher Marin Soljacic announced that they had used electromagnetic resonance technology to transmit power through the air without using wires to make a 60-watt light bulb glow. At present, some companies in Japan have begun to explore non-contact charging methods for electric vehicles that use electrom...
