The invention provides an integrated system of an electric vehicle wireless charging system, an alternating current wired charging system and a direct current wired charging system. The integrated system comprises a vehicle side integrated module and a ground integrated module. A first transmitting coil of the vehicle-side integrated module and a first receiving coil of the vehicle-side integrated module are strong coupling coils and serve as high-frequency transformers to realize an alternating-current wired charging function; a second transmitting coil of the ground integrated module and a second receiving coil of the ground integrated module are strong coupling coils and serve as high-frequency transformers to realize a direct-current wired charging function; the ground side is transmitted by the second transmitting coil and received by the first receiving coil, so that a wireless charging function is realized, and the second transmitting coil and the first receiving coil are in weak coupling; according to the technical scheme, the charging system is simplified through reasonable integration, the cost is reduced, the size of a charging part can be reduced, and the reliability can be improved.
本发明提供了一种电动汽车无线充电系统、交流有线充电系统与直流有线充电系统的集成系统,包括车侧集成模块以及地面集成模块;车侧集成模块的第一发射线圈和车侧集成模块的第一接收线圈为强耦合线圈,作为高频变压器,实现交流有线充电功能;地面集成模块的第二发射线圈与地面集成模块的第二接收线圈为强耦合线圈,作为高频变压器,实现直流有线充电功能;地面侧经第二发射线圈发射,第一接收线圈接收,实现无线充电功能,第二发射线圈和第一接收线圈为弱耦合;本技术方案通过合理的集成来简化充电系统,降低成本的同时可以减小充电部分体积,也可以提高可靠性。
