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.
