Abstract
This study proposes the application of an electric vehicle with embedded regenerative braking in a multi-directional wireless power transmission control system. It employs a slow-charging system for electric vehicles while driving and a fast inductive charging system at charging stations, carefully analyzing the hardware circuit architecture and chip module principles, and designing algorithmic procedures. By using a three-phase bridge inverter combined with motor Hall signal detection, and supplemented by a microcontroller feedback mechanism to control the timing of power transistor switches, the system synchronously adjusts the regenerative gain to achieve regenerative braking functionality. Moreover, the wireless charging station system proposed in this study can select the appropriate feeding direction based on three charging modes—G2V, V2G, and V2V—using wireless communication modules to transmit information between the power grid and the vehicle, thereby enhancing the convenience of charging. According to experimental results, this study effectively improves the energy utilization rate of the energy storage device in electric vehicles and the flexible scheduling capabilities of the charging station’s electricity supply.
