42-Volt Battery Fits In Standard Footprint


A 42-volt lithium battery has been delivered for pilot testing that is comparable to lead-acid longevity and performance, and fits into a standard battery casing.
The battery, produced by Lithium Technology Corporation, a pilot line stage rechargeable lithium battery manufacturer, produced the battery together with its German lithium polymer battery company partner, GAIA. The two companies have completed and shipped this first prototype 42-volt automotive battery to BMW under the auspices of the European Union-sponsored “Astor” program (Assessments and testing of advanced storage systems for propulsion and other electrical systems in passenger cars).
The Astor consortium consists of seven European auto companies: VW, BMW, Daimler Chrysler, Opel, Fiat, Volvo, and Peugeot.
The prototype lithium battery, which is now undergoing testing in Europe, delivers 7-8 kilowatts of power at ambient temperatures, with a capacity of 27 Amp-hours, a pulse power capability of up to 6 kilowatts for starting at an operating temperature of -25 degrees C, and an estimated life of 8 years.
It consists of unique flat cells housed in a standard European automotive battery casing, complete with a battery management system. The battery life, weight and performance compare more than favorably with competitive lead acid and nickel metal hydride systems, according to the company. The battery is designed to meet the 42-volt battery specifications of the Astor project.
