Abstract

The adverse environmental issues and climate change has compelled world to shift to renewable energy systems. Conventional IC engines are the major contributor for air pollution which is the main cause for the global warming. Therefore, EVs (Electric Vehicle) are the future of the automotive industry. The important issues faced by EVS are battery heat generation. Hence in order to remove heat efficiently from the EV battery CFD analysis of a passive thermal management system using PCM for Li-ion batteries is studied for three different discharge rates. Compared to bare cell, the cell with passive BTMS reduces the maximum temperature rise by 2%, 2.1% and 1% at discharge rates of 1.5 C, 1.0 C and 0.5 C respectively thus implying that the BTMS adopted is effective in removing heat from the surface of the cell.
