In this chapter, hybrid vehicle designs employing an internal combustion engine and battery-energy storage are considered. Battery electric and fuel cell vehicles (BEVs and FCVs) are also other alternative power trains. Hybrid electric vehicles incorporate a battery, an electric motor, and an internal combustion engine in the drive train.. A series hybrid vehicle is a type of hybrid vehicle that uses an internal combustion engine (ICE) to generate electricity, which is then used to power an electric motor that drives the wheels. This is in contrast to parallel hybrids, where both the ICE and the electric motor are connected to the wheels and can provide power directly. The series hybrid configuration offers several advantages.

In parallel hybrid architecture, two energy sources provide propulsion power. A parallel hybrid drive train blends the power of the IC engine and the electric motor mechanically with both sources supplying power to the wheels in parallel. The series-parallel architecture is a mix of series and parallel hybrid drive train.. Hybrid vehicle drivetrain Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power, and can come in many configurations. For example, a hybrid may receive its energy by burning gasoline, but switch between an electric motor and a combustion engine.
