Abstract :
Various charging algorithms are employed in commercialized battery chargers. This study was to undergo charging tests of four various chargers dedicated to 12-V lead-acid batteries. Our previous work on the Extended Kalman Filter based State-of-charge estimation in this comparison to make sure all batteries were charged/discharged to the same level. State-of-Health (SOH) is employed to determine the battery performance. The impact of the charging algorithms on the battery life time was evaluated. Experimental results show that the medium-speed charging when SOC is low with pulse charging at the high SOC keeps the longest life time of the battery.
