A New Method for Battery Characterization

Discover a new way to find battery model parameters from characterization experiments. You can use Model-Based Calibration Toolbox™, a tool traditionally used for conventional engine mapping, to estimate the lookup tables that describe the battery behavior. The simple structure of the battery equivalent circuit allows the toolbox to perform the optimizations using symbolic expressions, resulting in an efficient computational scheme. In addition, vectorization and parallel computing take advantage of the independence among most of the processes involved, enabling a complete fingerprinting of a battery across SOC and temperature in a matter of minutes on a common laptop computer. This talk may be useful to battery engineers and calibration engineers with experience in ICE calibration with an interest in electrification.
