摘　　要：现有电动汽车充电桩运行中存在一定的局限性,充电受到地点的限制,所达到的充电效率有限,磁耦合谐振式电动汽车线圈的设计与运用有效解决了这一困局,是一种无线充电方式,对空间载流线圈磁场分布情况进行分析,以此减弱线圈自感的影响,建立联谐振充电、串联谐振充电两种充电模式,并对此进行论证分析。针对串联电容谐振充电方式,为了提升传输距离与传输效率,通过系统仿真分析,可见能够达到95%充电效率,综合运用情况良好。Existing electric vehicles have certain limitations in full pile operation.Charging is limited by location,and the achieved sufficient efficiency is limited.The design and application of magnetic coupling resonant electric vehicle coils effectively solve this dilemma.This kind of wireless charging method analyzes the magnetic field distribution of the space current-carrying coil to reduce the influence of the coil self-inductance,and establishes two charging modes of co-resonant charging and series resonant charging.The article conducts demonstration analysis on this.For the series capacitor resonant charging method,to improve the transmission distance and transmission efficiency,through system simulation analysis,the article finds that the charging efficiency can reach 95%,and the comprehensive use is good.
