In this chapter, an overview of EVs and HEVs, their powertrain schemes, and onboard energy sources is presented. Different battery technologies are discussed, and in the case of hybrid electric vehicles, the feasibility of disconnecting the internal combustion engine (ICE) from the electric drivetrain is studied. Driving range, fuel economy, and emissions are evaluated over different driving cycles and at different vehicle powertrain hybridization ratios (HRs). The HR is an important factor that defines the ratio of ICE to battery system energy output for a hybrid electric vehicle. |
