ELECTRIC, hybrid and fuel cell vehicles have attracted significant attention in the past decades due to the exhaustion of fossil fuel consumption and their environmental concerns. Electric vehicles use electronic subsystems—in comparison to conventional vehicles, which include electric machines, power electronics, electronic continuously variable transmissions (CVT), onboard chargers, and embedded powertrain controllers. Advanced energy storage systems, such as Li-ion batteries, ultra-capacitors, and fuel cells, together with intelligent energy management algorithms, are introduced in the next generation powertrains. In addition to these electrification components or subsystems, conventional internal combustion engines(ICE), mechanical and hydraulic systems may still present. As a result, the complexity of new powertrain designs and dependence on embedded software is a cause of concern to automotive research and development efforts. This leads to an increasing difficulty in predicting interactions among various vehicle components and systems.Therefore, the design and implementation of the mechanical and electrical components need to be considered carefully. In order to understand the difficulty and prospected challenge of the vehicle electrification, this Special Issue is a review of the state-of-art contributions and new discoveries in the field of power electronics and applications for the electric vehicle.
