 The Hawaii Natural Energy Institute (HNEI) at the University of Hawaii and the Penn State University team has used computational fluid dynamics techniques and experimental validations to study battery performance since 1995. Their combined simulation and experimental effort has shown that battery modeling can accurately predict battery behavior during charging and discharging regimes for various types of battery chemistries from a single cell to a complete pack.
This project developed a reliable, computable, and fast predicting tool for battery cycle life through a full understanding and characterization of the nature of primary deterioration and failure processes in Valve-Regulated Lead Acid and Nickel Metal Hydride batteries for typical EV applications. The techniques and modeling capability developed under this effort will lead to improved cycle life performance, safe operation, and reduced cost of advanced EV batteries.
