Implementation and Verification of a Realistic Battery Model in the DEMKit Simulation Software

In this work we consider the implementation of the DiBu-model, a realistic model for battery State of Charge prediction, in DEMKit, a smart grid energy management toolkit. The implementation is discussed in detail and the differences between the ideal battery model previously used, and the new realistic model are shown. Lastly the model and implementation are validated by comparing the State of Charge predicted using DEMKit to the State of Charge derived from measurements on an actual battery. The predicted battery behavior matches reality quite well, the difference between the predicted and measured state of charge is generally less than 2 %.
