Some investigations on experimental and simulation results of EV Battery pack to provide ideal operating temperature for battery safety

Abstract

The battery also referred to as a chemical energy storage device—generates the required electrical energy. A cell is the basic component of a battery that produces energy. The significance of personal safety of person and vehicle service security has brought attention to battery thermal safety issues in recent years. To meet the anticipated problems and assure battery safety, the most recent innovations in battery thermal management (BTM) are being done. With a heat transfer intensify technique, the BTM technology improves battery safety while ensuring battery operation performance based on the battery's thermo-kinetic, mechanical, and electrochemical characteristics under both normal as well as abnormal operating settings. It is also crucial to prevent overheating and provide the optimal operating temperature for safe operation. Hence, creating a BTM system that is both secure and reliable. In this investigation, thermal calculations based on experimental data were performed and the outcomes of the ANSYS simulation were compared. It was found that the cell's highest temperature in ANSYS was 31.6°C, which was close to cell's average temperature. This temperature was in good agreement with the temperature obtained during actual testing (31.6°C). Key Word: Battery Thermal Management System, Li-ion batteries, Battery components.
