Abstract

This paper deals with the thermal and electrical modelling and simulation of an automotive high power battery cell. The electrical modelling is implemented for determining the electrical losses. The electrical losses are converted to heat losses and therefore a heat flow in the cell. The thermal modelling is based on a 1D implementation by means of discrete volume elements. The resulting simulation model includes the thermal and electrical behavior of a high power cell. All simulation models of the investigated cell are implemented and developed in the simulation environment Dymola, using Modelica programming language, [1]. Thermal and electrical measurements have been carried out to validate the simulation results of the thermal and electrical modelling. Three tests setups have been developed to measure electrical and thermal signals for determination of the parameters for the simulation model. The measurement and simulation results will be presented in this paper.
