摘要
将无线充电引入电动汽车领域,可以有效提高电动汽车充电的便利性和安全性,用户无需插拔充电枪即可完成充电,极大地降低了充电带给用户的额外使用负担。为应对多车对多桩的复杂应用场景,需要一种基于中心节点架构的多对多无线充电系统解决方案。首先,方案在地面端设备间引入了中心节点的概念,由中心节点负责管理多个地面端设备,中心节点与地面端设备通过CAN通信,组成一个局域网络。其次,方案提出了一套局域网络内的寻址和通信机制,实现对地面端设备的有效管理。最后,方案通过检测地面线圈电流频率来辨识地面端设备的方法,实现车载端设备可与任一地面端设备之间相互识别。
By introducing wireless charging into the field of electric vehicles,the convenience and safety of electric vehicle charging can be effectively improved,and users can complete charging without plugging and unplugging the charging gun,which greatly reduces the extra burden of charging on users.To address the complex application scenario involving multiple vehicles and multiple charging piles,a multi-to-multi wireless charging system solution based on central node architecture is necessary.First,the concept of a central node is introduced among the ground-side equipment,with the central node responsible for managing multiple ground-side devices.The central node communicates with these devices via the Controller Area Network(CAN),forming a local network.Second,the solution proposes a set of addressing and communication mechanisms within the local network to effectively manage the ground-side devices.Finally,in order to realize that the vehicle assemblies can recognize each other with any ground assemblies,this solution introduces a method to recognize the ground assemblies by detecting the ground coil current frequency.
