The High Energy Lithium Battery System in Electric Vehicle Propulsion 680454

A direct attack on the air pollution problems identified with the cities is to replace the internal combustion engine vehicle with one that is emission free. This paper deals with a small electric vehicle, designed for urban and suburban use, powered by batteries that are sealed off from the atmosphere. The power supply consists of a lithium/nickel fluoride, nonaqueous battery for total energy requirements, and a bipolar nickel/cadmium battery for the power required during acceleration and hill climbing. The object of this hybrid battery system is to obtain performance characteristics not available by either battery alone.
