Samenvatting
A prototype sodium/sulphur battery for electric vehicle propulsion is presented. The battery energy density for a 2 hr discharge is 100 Wh/kg and the power density at 2/3 OCW is 165 W/kg. This performance has been projected from the energy and power densities of experimental batteries. The performance data of the prototype battery are used to calculate the drive characteristics of an electric Chrysler T115 Minivan. These characteristics are compared with those of a T115 propelled with both lead acid and experimental sodium/sulphur batteries. (A)
