a review of the market prospects for battery electric versions of light goods vehicle, urban bus, and private car has been made based on the development of improved batteries. three particular battery types could have twice, five times and ten times the energy density of present lead/acid traction batteries. conclusions are that the best prospects are for the light goods vehicle and urban bus application. the private car market is likely to prove difficult to penetrate unless widespread refuelling points are available, or unless there is a serious petrol shortage leading to very high prices or rationing.
