Despite the high efficiency of the electric motor electric vehicles have only a limited range due to the low energy density of battery systems. The progress on cell level will be only evolutionary, but there is a high potential for weight reduction of other components of traction batteries. Within the FP7 project Smart and Safe Integration of Batteries in Electric Vehicles (SmartBatt) a consortium of nine partners from five European countries pushed up the energy density on system level from 80 to 148 Wh/kg by a smart lightweight design.enlithium-ion traction battery packs and systemlightweight designelectrical vehicleenergy densityconference paper
