Battery monitoring system for cell balancing

This article proposes a battery monitoring system to monitor charging and discharging of the battery. Li-ion energy storage batteries are the most sought-after batteries used in electric vehicles owing to their high-powered density, low rate of discharge, extended service life and ability to operate in almost any weather conditions. To protect of the battery pack, a battery management system (BMS) is necessary which helps in monitoring the health of the batteries to ensure that they do not cause any damage to the vehicle or to the user. A BMS monitors the operating parameters of the battery such as charging and discharging cycles of the battery, voltage & temperature. Normally, the monitoring system give input to protection devices that generates an alarm or disconnect the batteries connected to the load or the charging station if any of the system parameter crosses the predefined limit. In this work with BMS even distribution in charging and discharging of cells in battery pack are ensured to increase the life of battery.
