Modelling the Discharge of a Lithium Iron Phosphate Battery at Low Temperatures

This paper presents the development of a LiF eP O4 battery model which simulates the discharge process of the battery at low temperatures. The model is based on a second order R-C electric circuit model enhanced with a look up table that containes the dependency between the Open Circuit Voltage of the battery and its State of Charge at different temperatures. The paper presents in detail all the necessary steps for developing the model and also the validating process.
