Bipolar lead-acid power source (BILAPS) for hybrid vehicles

Abstract

In hybrid electric vehicles (HEV's) the requirements on batteries for energy storage are completely different from those in battery powered electric vehicles (BEV's). In order to come to a succesful development of HEV's, beside fullfilling the technical requirements, the battery has to have a long life time and must be cost effective. On the basis of TNO technology (patent pending), the development of a bipolar lead-acid battery has been started, together with a battery manufacturer (Centurion), having as final aim a commercial battery for hybrid vehicles and other high power applications. A prototype of 80 V has been built and tested, mainly for the purpose to identify the route to the final aim. Results of this prototype are discussed
