Electric Vehicles

EVs use an electric motor for traction, and chemical batteries, fuel cells, ultracapacitors, and/or flywheels for their corresponding energy sources. The EV has many advantages over the conventional internal combustion engine vehicle (ICEV), such as absence of emissions, high efficiency, independence from petroleum, and quiet and smooth operation. The operational and fundamental principles in EVs and ICEVs are similar, as described in Chapter 2. There are, however, some differences between ICEVs and EVs, such as the use of a gasoline tank versus batteries, ICE versus electric motor, and different transmission requirements. This chapter will focus on the methodology of power train design and will investigate the key components, including traction motor, energy storage, and so on.
