Abstract

This paper discusses about the impact of battery charging rate towards lead acid battery. Selecting wrong battery charger may result in premature failure of the batteries. This experiment provides a technical analysis which helps the user to determine suitable charger for their respective application.Two different charger was with similar algorithm anddifferent charging rate were tested on 48V series 12 V cells lead acid battery. The charging current, voltage and temperature were logged and analysed. The measurement design of experiment is presented in detail as well. The experiment was repeated for 4 times. The data taken from the higher charging rate and lower charging rate were compared.Fast charging of lead acid battery demonstrate in this paper shows it can reduce the charging time between 30 minutes to 1 hour.However,its capacityonly reach 97.3% of the full battery capacity compares to the slower charger while the thermal behaviour for both charger were comparable during the charging process.
