ELECTRIC AND HYBRID VEHICLES CHARGE EFFICIENCY TESTS OF ESB EV-106 LEAD-ACID BATTERIES

Charge efficiencies were determined for ESB EV-106 lead-acid batteries by measurements made under widely differing conditions of temperature, charge procedure, and battery age. The measurements were used to optimize charge procedures and to evaluate the concept of a modified, coulometric state-of-charge indicator. Charge efficiency determinations were made by measuring gassing rates and oxygen fractions. A novel, positive displacement gas flow meter which proved to be both simple and highly accurate is described and illustrated. (ERA citation 06:017068)
