Li-ion Battery Simulation

GT-AutoLion is the industry-leading Lithium-ion battery simulation software used by cell designers and OEMs. It predictively models the electrochemical processes within Lithium-ion cells.  Its fast and reliable electrochemical simulations are used to predict performance and life characteristics for any Lithium-ion chemistry under any operating condition. Every installation includes a comprehensive electrochemical materials database, reducing the burden for laboratory testing of electrochemical properties.

This single tool is used for standalone and integrated simulations. For standalone simulations, cell design engineers and scientists evaluate the applicability of various battery chemistries for their applications. R&D teams and design engineers can very easily and accurately simulate the impact of various chemistries (and any mixture of chemistries) on cell performance and life even before entering into a lab to fabricate a cell.  This provides the flexibility to optimize a battery in order to meet specified voltage, power, energy, and cost requirements.

For integrated simulations, electrochemical models are integrated directly into GT-SUITE’s electrical and thermal domains. This enables fast-running electrochemical models to be used in GT-SUITE system-level vehicle, thermal, and battery models, allowing performance and life prediction simulations to be run in an integrated environment.
