Experiments on a 12 V 50 Ah Valve Regulated Lead Acid (VRLA) battery indicated the possibility of 100 % charge in about 6 h, however, with high gas evolution. As a result, the feasibility of multi-step constant current charging with rest time was established as a method for fast charging in lead-acid batteries.
The effects of fast charging on lead-acid batteries used in motive power application are studied in this paper. A prototype laboratory-scale fast charger developed for the purpose was used to cycle the batteries in between 20 and 80 % state of charge.
Choosing the Right Charger for Lead-Acid Batteries The most important first step in charging a lead-acid battery is selecting the correct charger. Lead-acid batteries come in different types, including flooded (wet), absorbed glass mat (AGM), and gel batteries. Each type has specific charging requirements regarding voltage and current levels.
The effect of fast charging on the cycle life of lead-acid batteries used for e-rickshaw is demonstrated. The average coulombic efficiency of 93 %, maximum top of charge voltage of 2.6 V, and temperature rise of 5-6 oC. The predicted life of lead-acid batteries subjected to fast charging coupled with periodic equalizing charge is 1296 cycles.
This mode works well for installations that do not draw a load when on standby. Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.
