Several new types of ZEBRA batteries have been developed for various vehicle applications. The standard Z5 ZEBRA battery is produced primarily for the bus and commercial vehicle market. Other vehicle applications such as small city EV's, small hybrid vehicles and some large vehicles require very different specifications to the Standard Z5 battery. Most small EV's require low overall height batteries <250mm, small hybrids require high power- density >350W/kg and with extremely large vehicles there is an advantage in battery size being increased to over 40kWh. The development of cells and batteries to meet these different applications is described. A new low height cell has been developed and batteries produced from these cells have been tested in SMART vehicles. A high power cell has been developed and tested based on a multi-tube ceramic structure. A 60 cell prototype battery with a nominal energy of 6kWh has been tested. Using the present standard 32Ah cells, large 43kWh single unit batteries with a 30 second pulse power at 80% DOD of 80kW have also been developed and tested. The results from these various batteries show that the ZEBRA system can be developed to meet the many varied requirements of electric and hybrid vehicles. Potential future improvements are also discussed.
