DETERMINATION OF THE EFFECTIVENESS AND FEASIBILITY OF REGENERATIVE BRAKING SYSTEMS ON ELECTRIC AND OTHER AUTOMOBILES. VOLUME I. SUMMARY

A report is given of a study conducted by Lawrence Livermore Laboratory in which a determination of the effectiveness and feasibility of regenerative braking systems on electric and other automobiles was made. Regenerative braking concepts applicable to autos utilizing electric, hybrid, or heat engine power systems were evaluated to determine performance improvement, energy savings, and cost effectiveness. Two major conclusions were reached pertaining to privately owned autos driven 16,100 km/yr in an urban environment: (1) regenerative braking is cost effective and is recommended for use on electric and hybrid-powered automobiles, and (2) the addition of a regenerative braking system to the standard heat-engine-powered auto was not found to be cost effective. However, the regenerative system can be cost effective for heat engine powered commercial vehicles such as taxis, city buses, or delivery vans that see high annual usage under stop-and-go conditions.
