The battery management system plays a vital role in electric vehicles. Improper charging and discharging of the battery alters the chemical properties of the battery and thereby reduces its lifetime. Battery State of charge (SOC) is an essential parameter to be measured for designing a battery management system. Operating the electric vehicle battery above its nominal temperature leads to a blast of the battery, which may cause human loss. Hence the temperature of the battery has to be monitored properly. In order to reduce the depth of discharge of the battery, an SOC-based charging controller is designed with the help of Arduino and the developed control algorithm. This developed algorithm stops the operation of the electric vehicle when SOC of the battery goes below the threshold value and alerts the user when the temperature of the battery goes beyond the nominal range. This ensures the safe and proper handling of lithium-ion or lithium polymer batteries in Electric Vehicle.
Key words: State of charge (SOC) / Arduino
