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.
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.
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.
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.
Temperature rise, end voltage, and efficiency of charge were parameters considered for analyzing the fast-charging process. The reliability modeling and analysis of the e-rickshaw lead-acid batteries are carried out to study the effect of the said fast charging cum equalizing procedure on the Mean Time to Failure (MTTF).
Fast charging is a technique aimed to charge a battery quickly in much lesser time (about one-third of the time required for a regular charging cycle or even lesser). This is achieved by suitably varying the magnitude of the charging current as a function of the state of charge. Fast charging is an area of research from the mid-twentieth century.
