Thermal management design for battery used in automobiles are very important in order to manage the thermal dissipated by operating components. This research aims at performing design optimization of a thermal management system for battery modules in modern vehicles. An active cooling systems is proposed where oil cooling system is used for battery modules. The causes of problem due to improper thermal management of battery is deployed to identify the potential failure modes and causes so that improvements can be made for battery modules. The design for the thermal management system were done with SOLIDWORKS. To maintain the temperature of battery helical passage and exterior flow passage is used, the radiator coolant oil is used as the fluid to conduct heat from battery during its passage time. The thermal management system for battery modules is simulated using ANSYS CFD software. Results from simulation were validated and have shown good agreement based on the data collected at various vehicle speeds.
