Bidirectional Power Transfer between HEVs and Grid without External Power Converters

Abstract

This paper proposes methodologies to realize bidirectional power transfer between hybrid electric vehicles (HEVs) and the power grid for the most common HEV configurations. Only the internal power electronics and electric machines of the vehicle's propulsion system are being used, thus avoiding additional external power converters. Theoretical analysis and simulation results verify the effectiveness of the proposed methodologies.
