Summary: This article proposes an integrated converter for electric vehicles (EVs) with various charging capabilities and the use of a switched reluctance motor (SRM). The converter can provide driving power during EV operation and charge the battery when the vehicle is idle. It includes power factor correction (PFC) charging for AC charging, bidirectional switches for both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) charging, and a four-quadrant DC-DC converter (FQDDC) for fast charging via a DC source. The proposed converter eliminates the need for additional non-integrated circuits, reducing the total number of switches and achieving a standstill rotor at appropriate positions.

Summary: This study investigates the acceptance of Vehicle-to-Grid (V2G) charging among electric vehicle (EV) drivers. The findings suggest that clear communication, financial compensation, real-time insight, and user-friendly interface contribute to higher acceptance. However, uncertainty in battery state-of-charge, increased planning requirements, anxiety about reaching destinations, and restrictions on personal vehicle use are major barriers. The study also reveals that actual experience with V2G charging influences perceptions, with concrete factors carrying more weight than abstract concerns.
