Recent studies have demonstrated that fast charging techniques can significantly extend the effective daily range of lead acid battery powered EVs. Further, other research has shown that the total lifetime energy delivery of suitable VRLA batteries can be increased markedly through partial state of charge cycling. A research team composed of Arizona Public Service (APS), CSIRO Division of Minerals (CSIRO), Electric Transportation Applications (ETA), and Hawker Energy Products, Incorporated (HEPi) has been assembled to conduct a detailed laboratory and field program to develop operating regimes that will improve lead acid battery performance in EV applications using fast charge and PSOC operation. Research is being conducted under the cognizance of the Advanced Lead Acid Batttery Consortium, both in the laboratories of CSIRO and HEPi, and in the electric vehicle fleet of APS and ETA.
