Partial State-of-Charge Operation and Modifications to Extend Battery Life

Market needs from idle start–stop vehicles are requiring the lead–acid battery to operate at partial state-of-charge (PSoC), while maintaining a long life. Other energy-storage applications, such as the harnessing of renewable energy, opportunity-charging of fork trucks and heavy road trucks are also requiring PSoC operation. To meet these challenging demands, many have proposed more costly solutions that include lithium batteries and valve-regulated lead–acid batteries batteries. Starting with the flooded lead-acid battery, this presentation with highlight many incremental modifications and their impact to extend cycle-life and offer a pathway to meet the challenging industry goals. The presentation will also address the impact on other key functions that include charge-acceptance and water loss.
