Thermal Distribution in a Pack of Cylindrical Batteries

Application ID: 76291

This example demonstrates how to model the temperature distribution in a battery pack during a 4C discharge.

The pack is constructed by first coupling two cylindrical batteries in parallel. Six parallel-connected pairs are then connected in series to create the full pack. (This is also called a 6s2p configuration.)

The symmetry of the problem is used twice so that only the temperature distribution for three batteries needs to be solved for.

Three instances of the Lumped Battery interface are used to generate the appropiate heat sources, which are then coupled to one Heat Transfer interface in a 3D geometry.

This model example illustrates applications of this type that would nominally be built using the following products:
