Liquid-Cooled Prismatic Battery Pack
Application ID: 140511
This example models the temperature profile in a liquid-cooled prismatic battery pack during a high-rate charge.
The pack consists of 16 prismatic battery cells connected by busbars, placed on an aluminum plate containing four cooling channels. The battery pack is assumed to have two faulty cells, featuring higher ohmic resistance values in comparison to the remaining cells in the pack. All other battery cell properties are identical.
The Battery Pack interface using the Two electrodes model is used to set up the current conduction and cell chemistry in the jelly roll, current conductors and busbars. The heat transfer in the battery cells, busbars and cooling plate is modeled using the Heat Transfer in Solids interface, whereas the Heat Transfer in Pipes and the Pipe Flow interface are used to define the convective heat transfer in the cooling channels.
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.
