This training course is designed for individuals interested in understanding and simulating the thermal effects in batteries. The course provides hands-on experience using Simcenter STAR-CCM+, a leading computational fluid dynamics (CFD) software, to model and analyze battery thermal management.

In the chapter about Ohmic Heating, participants will learn how to set up Ohmic Heating simulations in Simcenter STAR-CCM+. In the example, the battery chemistry is modeled as a user-defined battery where heat is only applied to the core parts. Hence, heat in tabs, connectors and busbars needs to be modeled separately. A pouch cell, consisting of three battery cells in series, will be used as an example to demonstrate the Ohmic heating setup.

 In two chapters we explore different methods to set up thermal runaway simulations. Both approaches allow participants to focus solely on understanding and simulating the thermal effects without the complexity of full battery modeling. Participants will analyze the heat generated in one battery cell and judge if and when other cells follow into thermal runaway.
* One method involves using parameters, field functions, tables and reports, allowing participants to manipulate the simulation parameters to study different thermal runaway scenarios.
* The second method utilizes the Heat Release model in Simcenter STAR-CCM+, providing a detailed and accurate representation of the thermal runaway phenomenon.
* Both examples use cylindrical cells.
If you are interested in simulating the chemistry and physics of batteries, we recommend considering our courses ILT030010 or ILT030012. These courses focus on the setup of battery geometry and chemistry, either by utilizing tbm files from Simcenter Battery Design Studio (ILT030012) or by creating user-defined battery models (ILT030010).
