Battery Management System in Electric Vehicle

A PIC-microcontroller-based Battery Management System for electric vehicle applications has been developed to provide battery monitoring, charging control, and protection. The proposed system integrates voltage, current, and temperature sensing with relay-based charging control, LCD indication, and buzzer warning. The controller continuously evaluates battery operating conditions and provides fast or slow charging depending on battery voltage while monitoring thermal conditions to improve safety. The integration of the hardware components and embedded control program demonstrates the successful implementation of the proposed BMS prototype. The developed system provides an economical approach for maintaining battery operation within appropriate limits and improving the safety and reliability of EV battery systems. According to the project report, the complete system was successfully designed, implemented, and tested.
