ABSTRACT Vehicle electrification is progressing significantly and is changing the architecture of future cars. This trend is a result of the need for higher vehicle efficiency and the desire to diversify the energy sources used for transportation. Voltec vehicles such as Chevrolet Volt and Opel Ampera are electric vehicles (EVs) with extended driving range. They operate as an EV as long as there is useful energy in the battery. However, unlike a pure battery EV, they do not suffer from lost vehicle utility when the battery is depleted. Volt and Ampera can continue operation by using an internal combustion engine as energy converter. Within the framework of this chapter, in addition to the focus on the current Voltec battery and propulsion system technologies, a brief history of the General Motors EV activities is also provided.
Keywords: Battery, Chevrolet Volt, Opel Ampera, Propulsion system, Voltec.
