This International Standard establishes a vocabulary of terms used in International Standards generally in relation to electric road vehicles. It is not intended to give definitions of all parts within a vehicle, but focuses on terms specific to electric road vehicles.

Figure 1 schematically groups the components of an electric road vehicle.

NOTE The definition of "electric road vehicle" is generally understood. With the development of new technologies for hybrid vehicles, fuel cells and others, appropriate definitions of the expanding family of electric road vehicles require further consideration.
