Integrated Traction/Charge/Air Compression Supply using 3-Phase Split-windings Motor for Electric Vehicle

High cost, no-ideal driving range and charge time limit electric vehicle market share. Facing these challenges, an in-tegrated motor drive/battery charger system has been proposed by Valeo. A further advancement, based on this system, is present in this paper; for the first time, the integration of traction, charging and air-compressor supply modes is proposed and tested by real-time experimentation. This integrated system is expected to in-crease the vehicle component compactness and power, therefore potentially reduce the cost and battery charging time. An overall and unique control scheme is detailed to achieve the three main operating modes: traction, charging and air-compressor supply modes. The real-time experimentation results show the system fea-sibility
