Analysis, Simulation on Single Cell of Lithium-Ion Battery

Mechanical engineering

Lithium-ion (Li-ion) battery performance and safety in electric vehicles (EVs) depend on maintaining ideal temperatures. The hybrid Thermal Management System (TMS) that incorporates a car's cabin air conditioning (VCAC) system is the subject of this study. A simulation examines the amount of heat produced by a single Li-ion cell at different charging and discharging rates and ambient temperatures. The efficiency of VCAC in regulating cell temperature—including cooling efficiency, temperature uniformity, and reaction time during temperature fluctuations—is the main subject of this study. In order to comprehend how VCAC affects overall module temperature control, these single cell results are then interpreted for a larger battery module (44 cells in series or parallel arrangement). The purpose of this study is to demonstrate how VCAC-based hybrid TMS can be used to maximize Li-ion battery temperature regulation in electric vehicles. The work provides important insights for creating battery thermal management systems for next-generation EVs that are more dependable and efficient by examining thermal behavior and extrapolating it to a bigger module.
