Title: A Modelica library for Thermal-Runaway Propagation in Lithium-Ion Batteries
Authors: Christian Groß and Andrej W. Golubkov
Abstract: Based on the Thermal Runaway (TR) experiments con-ducted in our laboratory a simple method of describ-ing a battery’s thermal behaviour was developed.Inthe approach - which we callsimple tracing method-the temperature rate measurement from Accelerating RateCalorimetry (ARC) during a TR experiment is approxi-mated to determine the thermal behaviour of the model.This method was implemented in Modelica using Dymola.Alongside the implementation of the TR model a com-plete Modelica package with useful models for TR prop-agation simulation was developed. The package called“BatterySafety”serves as a foundation for further modeldevelopment to investigate TR propagation and physicalcounter measures in greater detail. The focus of all themodels in the package was efficiency, intelligibility anduser-friendliness. With this approach we are able to simu-late TR propagation of a complete battery pack.
