Developments in Hybrid Electric and pure Electric Vehicles are intended to improve the operational efficiency of road vehicles. Regenerative braking, which has long been established in rail vehicles, is integral to efficiency improvement, with up to 30% of overall traction energy demand satisfied by energy saved during deceleration. The paper discusses the demands on regenerative and friction braking, and cites an example of a Hybrid heavy truck, which uses minimal friction braking over a particularly hilly driving route. Improving the onboard energy storage device, by incorporation of an ultra capacitor, further reduced the friction brake use.
