Shown here is the screen representation of a battery pack cooling simulation in STAR-CCM+. The battery pack was designed in BDS and the flow and thermal simulation conducted in STAR-CCM+ using the Battery Simulation Module (BSM).

Through our long term collaboration with Battery Design LLC, a leader in electrochemical model development, CD-adapco is able to offer an expansive solution for coupled thermal-electrochemical simulations. Shown is a scalar plot of Specific Ohmic Heat Source on battery connectors.
Temperature Distribution on a Cylindrical Battery Pack
Battery Design Studio (BDS)
Developed to provide a simulation environment for the analysis and design of the electrochemical system and detailed geometry of a single battery cell. A choice of three battery performance models is offered to the user, enhanced with significant developments relevant to contemporary cell design, such as multiple active materials or particle sizes. Through its integrated environment, BDS offers its users a faster battery design process and provides a standard platform connecting material suppliers, cell designers and battery users.
STAR-CCM+ Battery Simulation Module (BSM)
Combining the electrochemical solver of BDS with the flow & thermal solver of STAR-CCM+, STAR-CCM+ BSM has the ability to calculate the 3D thermal, fluid and electrochemical properties of lithium-ion battery cells on several length scales, starting from each finite volume/e-cell within a battery cell, to the entire pack, including thermally-conducting parts such as metallic connectors at high discharge/charge rate. This is achieved through a closely coupled 3D simulation which returns the electrochemical and thermal properties as complex distributions over the electrodes and battery cells. The internal construction of each cell is taken into account without the need to resolve all its layers independently, balancing computation effort with appropriate detail.
