Abstract

The automotive industry is gradually shifting towards electric and hybrid vehicles which calls for the need of research in Battery Thermal Management System(BTMS). The two main variants of batteries that are of prime importance are Li-ion and Lead-Acid. Former have a higher energy density, which makes them more suitable for portable applications. Furthermore, they offer a 40-50% weight reduction and 20-30% volume reduction. The major obstacle in their usage is large heat generation during operation. Hence, there is a need for an efficacious thermal management system. Present work targets on making the BTMS using air cooling more effective by optimizing the channel shape from which the coolant flows. The numerical simulations were performed using the commercial code Fluent®. The efficacy of different optimized channel shape was studied at different values of Reynolds Number (Re) based on channel inlet length. There was a reduction in maximum temperature of the battery by 1 °C when Reynolds number was increased from 169 to 338 The optimized channel shapes further brought down the maximum temperature by up to 3°C throughout the length of channel thereby bringing the battery in its favorable working condition.
