Abstract
A Battery Management System (BMS) is an electronic control system that monitors and manages rechargeable battery packs. Secondary batteries are commonly used as the storage of energy produced by solar panels. However, the utilization of a battery without proper management can cause damage due to overcharging and over-discharging.
The BMS continuously monitors cell voltages, current, temperature, and state of charge while protecting potentially damaging conditions such as overcharging, over-discharging, excessive current, and temperature extremes. Advanced systems incorporate cell balancing to maintain uniform charge distribution across multiple cells, thermal management to regulate operating temperatures, and sophisticated algorithms to estimate battery state of health and remaining useful life.
This study aims to design a battery management system (BMS) on a Valve Regulated LeadAcid (VRLA) battery. The method used was the battery State of Charge (SOC) estimation using Coulomb Counting (CC) method. The results showed that the BMS was successfully designed and implemented to automatically cut-off the current when the SOC value is 100% (charging limit) and 20% (discharging limit)
