Thermal modeling of batteries for EV energy management

The temperature of a Lithium-ion battery was investigated, a 3D modeling approach was adopted. With the assitance of ANSYS Fluent software, the evolution of the temperature was predicted for one cell and then the work has been extended to a module of several cells. It was found for both cases, that the temperature increased when the discharge current increased. Regarding the module, the maximum temperature was achieved by the middle cells. A cooling air system was introduced into the module with different inlet velocities, and it was noticed that the temperature decreased with the increase of the velocity.
