The Electric Vehicles (EVs) are heavily dependent on electrical energy storage technologies (ESTs) and EVs need power condoning units (PCUs) for operations like battery charging, power flow control of electric motors and supplying power to the auxiliary power load in a EV. The charging infrastructure for the EVs and Transit busses is one of the key requirements in increased usage of electric automotive. the electrical energy can be stored by converting it into the various domains like, electrochemical, electrical, chemical, thermal and mechanical. Out of these, the electrical, electrochemical and chemical storage systems are mostly used in EVs. Also, The power conditioning units (PCUs) in an electric vehicle (EV) has multiple individual power converters which controls the power flow among various energy storage devices, power sources and EV motor. The PCUs ensure the reliable, controlled and optimum charging of batteries used in EVs. This book presents the various storages systems for EV, power converters topologies for EV charging and charging infrastructure for electric transit buses. The recent advancements and comparative study of storage and charging schemes are emphasized.
