HIGH POWER BATTERY CELLS DEVELOPED FOR MILD AND STRONG HEVS

摘要

Despite their many advantages, the introductionrnof hybrid electric vehicles (HEVs) into the marketplace continues to be a challenge due to the cost,rnsafety and life of the batteries. Researchers atrnGeneral Motors LLC (GM) and Hitachi AutomotivernSystems Americas Inc. have investigated how thernvehicle propulsion system requirements are tied torncell selection on the basis of performance, safetyrnand packaging. A general cell format criteria andrnperformance comparison of various options leadingrnto selection of this particular high power cell wasrnstudied.
