Rapid Prototyping of G2V/V2G DWPT Charge-Control and Grid-side Power Management for EV Applications

Development and testing of the impact of different wireless charging systems on Electric Vehicle(EV) infrastructures involves considerable effort as it requires different types of coil structures embedded in roadways, different types of EVs, and also requires a test-track setup. Moreover, it requires high speed real-time data measurement and communication to/from an in-motion EV which makes it involving coordinating and testing new control algorithms for such applications. To address this issue, a bidirectional wireless charging system model is proposed in a hardware-in-loop environment, which enables rapid control prototyping of such systems from a benchtop setup. The proposed system can emulate Grid-to-Vehicle(G2V) and Vehicle-to-Grid(V2G) charging profiles for stationary and dynamic charging scenarios. As an additional feature, a versatile grid-side power management algorithm is also developed which significantly reduces grid-side power transients resulted from different types of wireless charging profiles.
