The invention discloses an electric vehicle static electric field coupling type wireless charging system and an electromagnetic safety and matching design method. The design method comprises the following three steps: firstly, on the basis of the basic principle and structure of an electric field coupling type wireless power transmission system, a coupler design that the area of a transmitting end coupling pole plate is larger than that of a receiving end coupling pole plate is adopted, and meanwhile, a transmitting end coupler and a receiving end coupler are reasonably arranged, so that a vehicle only needs to be parked in a parking space frame line; and the electric energy can be efficiently and stably transmitted. And secondly, an electromagnetic safety design is adopted, a high-strength alternating electric field generated during wireless charging is shielded, and the electromagnetic environment influence on the nearby space during charging is reduced. An infrared detection device is adopted to capture whether an organism approaches or not during charging, and an organism approaching safety response mechanism is established. And finally, certain supporting measures are taken, the security and protection functions matched in the vehicle key and the vehicle are comprehensively designed, and the supporting integration of the system is realized.
本发明公开了一种电动汽车静态电场耦合式无线充电系统、电磁安全及配套设计的方法。该设计方法包括三大步骤:首先,本发明基于电场耦合式无线电能传输系统基本原理、结构,采用发送端耦合极板面积大于接收端耦合极板的耦合器设计,同时通过合理布局发送端耦合器和接收端耦合器,实现车辆只需停放在车位框线以内,就能高效稳定传输电能。其次,采用电磁安全性设计,将无线充电时产生在高强度交变电场屏蔽,减小充电时对附近空间的电磁环境影响。采用红外探测装置,捕捉充电时有无生物体靠近,并建立生物体靠近安全响应机制。最后,采取一定的配套措施,综合设计车钥匙、车内配套的安防功能,实现系统的配套集成。
