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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
