A simple battery model for hybrid system simulation has been developed. Given battery temperature and charge or discharge current, the model calculates the battery state-ofcharge, voltage, gassing current, heat evolution, and ageing. The model has been implemented in Simulink.

Note: Following publication of this paper, many changes were made to the PVToolbox battery model in response to deficiencies in the model described in this paper.
