Abstract
Two different battery thermal management design for a battery cell is presented. The design is intended to represent the cooling procedures and heat transfer phenomena. Computational fluid dynamics were used for both steady-state simulation and time-dependent condition. Inside the battery, a lumped amount of volumetric heat source is considered. The determined heat generations data are taken from isothermal battery calorimeter experiments. Water was considered as cooling liquid. The design is simulated to distinguish the temperature gradient over surfaces of the cell. Furthermore, the temperature evolution outcomes are simulated. It was concluded that by using the liquid at 15 °C, at 8C discharge rate the temperature moderately declines with raising liquid flow rates, recording a maximum of 25 °C for the liquid at 15 °C.
