EAI Tests Lead-Acid Battery Products in Start-Stop Applications

The automotive industry has traditionally been one of the most important markets for lead-acid batteries. Over the past several years, the auto industry has developed various approaches to improving fuel economy through electrification of the vehicle drive train. Almost all recent market forecasts indicate a high sales potential for vehicles with a start-stop system, as a simple, inexpensive solution that can achieve reductions in carbon dioxide and increases in fuel economy, while the electric system and the size of the vehicle remain for the most part unchanged. Regenerative braking lowers carbon dioxide emissions further and increases fuel economy benefits at minimal cost. The lead-acid battery industry is well positioned to meet the challenges these vehicles present. In recognition of this this positioning of lead-acid batteries, the Advanced Lead Acid Battery Consortium and The US Department of Energy (USDoE) through its Idaho National Laboratory have contracted with Electric Applications Incorporated to baseline the progress made in lead-acid batteries over the past decade by testing multiple manufacturers battery products using the US Advanced Battery Consortium (USABC) Battery Test Manual For 12 Volt Start/Stop Vehicles. This project utilizes a testing process aimed at analyzing “gaps” between current lead-acid battery performance and the end of life characteristics targeted by the USDoE and the North American vehicle OEMs through the US Advanced Battery Consortium (USABC).
