Description

technical field

[0001] The invention relates to a wireless charging system for electric vehicles, in particular to a magnetic resonance type wireless charging integrated device for electric vehicles and a control method thereof. Background technique

[0002] With the advancement and development of science and technology, automobiles are gradually getting rid of their dependence on oil, and countries all over the world have begun research on electric vehicles. The 8th Global New Energy Vehicle Conference was grandly opened at the Beijing National Convention Center on December 14, 2017. As the world's largest electric vehicle market, China is ushering in the era of "double points" new policy. The Netherlands, Norway, Germany and California, USA Other places have made it clear that traditional fuel vehicles will be completely canceled in the future, and the electrification of vehicles is the general trend.

[0003] Throughout the country and abroad, the use of electrification ...
