AIR- Based Battery Thermal Management System

Abstract: Airbased Battery Thermal Management System (BTMS) ensures efficient monitoring and control of battery parameterssuch as voltage, temperature, and current to maintain optimal performance and longevity. This research delves into the development of an advanced BTMS that continuously senses battery temperature and employs air cooling through fans to keep the temperature within permissible limits. The system is designed to enhance battery safety, reliability, and lifespan by preventing thermal runaway and promoting efficient thermal regulation. Through extensive testing and simulation, the proposed BTMS demonstrates significant improvements in maintaining battery temperature stability, ultimately contributing to enhanced opera- tional efficiency and prolonged battery life. Lithium-ion batteries are considered as the best choice available for the energy storage systems, for portable devices, electrical vehicles and for smart grid, thanks to their high energy and power densities, lack of memory effect and life cycle. However, heat generated by these batteries remains a challenge. Without an appropriate Battery Thermal Management System (BTMS), the lithium ion battery surface temperature can increase very rapidly and thus creating hazard for the user and the equipment. This paper presents a Air based Battery thermal Management System with variable fan speed
