Cloud-based Multiphysics Simulation of Battery Cooling

Presentation of the problem and objective of the experiment

Automotive battery packs are nowadays mostly cooled by cooling plates. Cutting edge applications, however (especially for rapid charging), require using immersive cooling. In rapid charging of battery packs, up to 50 kW of thermal energy must be dissipated. Cold plate cooling is insufficient to fulfill this requirement. That's why it's important to provide SME manufacturers with tools that allow designing immersed cooled battery packs quickly with the use of cloud-based simulations. Thus shortening the design process and lowering its costs. 

Short description of the experiment

In this experiment, we propose to develop a workflow that will allow Wamtechnik to utilize cloud-based simulations in its design process. We start with the definition of the initial geometry of the battery module. Then we will run large-scale CFD simulations to check the fidelity and accuracy of the results. Later, the QSA battery simulation software will be coupled with an external CFD solver. This will allow simulating the electrochemical cells and heat generation (already fully handled by the QSA solver) and the complex 3-D flow field inside the battery pack (a full-scale 3-D CFD solver needs to take care of that). Finally, the coupled model will be handed over to the Wamtechnik team that will adopt the tools and optimize the design.
