Li-ion Battery Simulation
GT-AutoLion is the industry-leading Lithium-ion battery simulation software used by cell designers and OEMs to predict performance, degradation, and safety for any Lithium-ion cell. It predictively models the electrochemical processes within Lithium-ion cells using a fast and reliable, electrochemical, physics-based approach.
GT-AutoLion can be used to predict how various Li-ion chemistries and cell designs will perform before Li-ion cells are prototyped or even available for testing. With GT-AutoLion, a Li-ion battery’s performance can be predicted under any load, including constant current (voltage drop and temperature rise shown to the left) and more dynamic loads. GT-AutoLion uses the phiscio-chemical Pseudo-2D model pioneered by Doyle, Fuller, and Newman to predict performance. On top of the Pseudo-2D model, GT-AutoLion also includes a swelling model capable of predicting stress, strain, and pressure in a cell as active material expands during lithiation. Finally, every installation includes a comprehensive electrochemical materials database, reducing the burden for laboratory testing of electrochemical properties.
