Abstract

Battery storage is an integral subcomponent of many remote autonomous energy systems. An accurate battery model is essential for the analysis of the system performance. The accuracy of the performance estimate is therefore open dependent on how well the behaviour of the battery is understood. This paper presents computational submodels that predict the voltage vs. current behaviour and internal losses of a vented lead acid battery and illustrates their utilization in practical simulation. A complete and compact methodology for the determination of the battery model parameters that is easily adaptable for different battery types is also presented. The method can be applied routinely. Required instrumentation is minimal, only battery voltage, current and temperature are recorded. The model parameters for a vented lead acid battery determined with this method are also given.
