The automotive industry is evolving very quickly to lower consumption and reduced polluting vehicles. In the short-term (2 - 3 years) new vehicles will be introduced with integrated starter alternators for stop and go function (zero-emission at idle). Battery weight and volume should be reduced, but cycle life must be improved. The performance required is very demanding, but high power VRLA batteries can cope with the requirements. New technologies (such as Ni-MH, Li-ion, ...) will not be adequate for these vehicles because of the high cost. Exide Technologies is presently developing a high power Orbital VRLA battery with the following minimum performances: specific power > 500 W/kg; fast charge < 4 min; calendar life > 5 years; cycle life > 1000 deep cycles. These achievements will not be made at expense of a higher cost, which should be maintained under the car manufacturers requirements (< 150 dollars/kWh), and as a consequence, the high power VRLA batteries will be the most economical power source of the new vehicles with 42V power net architecture. In order to give a solution for the increasing demand of power within the oncoming generation of vehicles, Lear Corporation is developing a new electrical and electronic distribution system for the 42V vehicle architecture.
