Lead-free battery systems are already on the market in high-voltage electric and hybrid-electric vehicles, and are expected to grow significantly over the next decade. These alternatives offer several performance advantages over conventional lead-acid batteries. With additional development to achieve mass production volumes, these alternative batteries could also compete with emerging 42-volt (higher voltage battery systems to satisfy increased electrical demand) and the standard 12-volt systems. AQMD Contract # 01111 April 2003 DEVELOPMENT OF COMMERCIAL PROTOTYPE ADVANCED VALVE-REGULATED LEAD-ACID BATTERIES FOR ELECTRIC VEHICLES Contractor Trojan Battery Cosponsors Trojan Battery Company Project Officer Lisa Mirisola Background The advanced lead acid battery proposed for use in electric and hybrid electric vehicles is a totally maintenance free design using the valve regulated lead acid battery (VRLA) technology. The strong economic advantage in using advanced lead acid batteries in these applications is that these batteries can be manufactured using existing commercial battery manufacturing equipment , without the need for substantial capital investment. A full recycling infrastructure is also in place for lead acid batteries. For EV and hybrid...
