Battery Thermal Management
GT-SUITE provides the ideal platform for optimizing battery thermal management systems
Solution Overview
Integrated Electro-Thermal Modeling
In GT-SUITE batteries are optimized on the cell, module, and pack level. The temperature and current distribution within the cells and pack are simulated to predict the battery performance under a variety of dynamic conditions.
These battery models are integrated with the electrical system and coolant system to capture the transient effects on battery performance, heat generation rate, vehicle range, and more.

Battery Thermal Management FAQs
Find answers to common battery thermal modeling and simulation questions.
-
Can GT-SUITE simulate the full battery thermal system — cells, modules, and pack — in a single environment?
Yes. GT-SUITE models battery thermal behavior at the cell, module, and pack level all within the same simulation, while integrating that thermal model with the electrical and coolant systems. This means engineers can capture transient interactions like heat generation and temperature distribution, and see how those factors affect vehicle range, all without switching between separate tools.
-
How does GT-SUITE handle battery cooling strategy evaluation without running expensive 3D CFD simulations for every design variant?
GT-SUITE combines 1D flow modeling with 3D finite element thermal analysis through its GEM3D tool. This hybrid approach delivers accurate pressure drop and temperature distribution results in a fraction of the time it would take using full 3D CFD. As a result, engineers can compare cooling topologies such as immersion cooling, cold plates, air cooling, or two-phase refrigerant systems, and land on the best configuration early in development, without the computational cost of running CFD on every variant.
-
Can GT-SUITE predict thermal runaway propagation across a battery pack?
Yes. GT-SUITE includes purpose-built capabilities for predicting how thermal runaway propagates through a battery pack, which supports both safety validation and regulatory compliance work. Engineers can use these models to test and refine design decisions that reduce propagation risk long before a physical prototype exists.
-
Does GT-SUITE support electrochemical battery modeling, and how does it connect to system-level thermal simulation?
Yes, through an optional link to GT-AutoLion, which provides physics-based electrochemical cell modeling. This connection lets engineers predict aging, state of health, and how heat generation is distributed spatially within the cell. It also means system-level thermal and energy management decisions can be based on real cell-level electrochemistry rather than relying on simplified lookup tables or empirical assumptions.
