Electric Vehicle Battery Development

Various types of lead-acid batteries have developed because of different market needs. The small, uncertain market for electric vehicles has been met by modifying traction-type or golf-car type lead-acid batteries. Recently, governmental stimulation of the market for passenger electric vehicles has resulted in the design and development of batteries to meet specific performance goals for electric vehicle propulsion. The approach which the Eltra Electric Vehicle Group/C&D-Prestolite has taken toward meeting the governmental goals involves the use of expanded metal, non-antimonial grids, overpasted plates, reduced electrolyte and an enveloped, glass mat retention system.
