In order to reduce the CO2 emissions and the consumption of fossil fuel, the micro (12 V), medium (144 V) and full (>200 V) hybrid electric vehicles (HEV) will become the preferred mode of transport in the near future. The 12-V valve-regulated UltraBattery has demonstrated excellent endurance under high-rate, partial state-of-charge (HR-PSoC) operation and the Honda Insight, a medium HEV, powered by these batteries has surpassed 100,000 miles at the Millbrook Proving Ground. Micro-HEVs use one 12-V battery similar to the conventional automobile with the incorporation of idling-stop and regenerative braking. Medium-HEVs also use idling-stop and regenerative braking with the additional requirement of acceleration. Therefore, the cost increase of micro-HEVs is lower compared with that of medium-HEVs. In Europe, a 12-V valve-regulated version will be used in the micro-HEVs, while a flooded-electrolyte version for further cost reduction is preferred in Japan. Therefore, the authors have developed a flooded-electrolyte UltraBattery for such applications. The flooded UltraBattery is a combination of improved features from the flooded SLI battery and the UltraBattery technology. With this combination, the cycling performance of the flooded UltraBattery is 4 times longer than the improved flooded SLI battery. In this paper, the cycling performance of a flooded UltraBattery will be discussed in detail.
