NICKEL-ZINC BATTERIES FOR HYBRID VEHICLE OPERATION

The goal of this study was to evaluate and improve the characteristics of nickel-zinc secondary batteries for use in hybrid electric vehicles. The hybrid electric vehicle has a propulsion system consisting of a heat engine and a battery. The heat engine supplies steady state power, while the battery provides the transient power demands. The primary purpose, for hybrid propulsion, is to reduce exhaust emissions from street vehicles. The nickel-zinc secondary battery's possesses a unique combination of properties which makes it a strong candidate for use in hybrid electric vehicle propulsion systems. These properties include high energy density (25 Wh/lb), a flat discharge, and the ability to charge and discharge at high rates (greater than 100 Wh/lb) and low temperatures. Another feature of interest for vehicle propolsion use is the fact that electrode materials are plentiful and of reasonable cost. However, several possible problem areas do exist regarding the use of nickel-zinc cells, as presently designed, for this application; these are short cycle life and fairly high maintenance.
