Title: A Two Branch SIMULINK Model of the Lithium Polymer Battery
Authors: Dipesh D Patel and Ziyad M Salameh
Abstract: The paper discusses the Simulink model of lithium polymer battery. Model parameters are temperature and state of charge dependent. This model is two branch (parallel R-C) model. 2-D Look-up table method is used to represent the relation between model branch parameters and state of charge. Matlab user defined function is used to calculate the open circuit voltage and internal dc resistance. One whole block is dedicated to state of charge calculation. This block is able to autonomously detect the transition from charge to discharge and vice versa. Also if charging or discharging current stops flowing, it resets the current integrator initial condition to the last state of charge calculated. Comparison between experimental and model results showed about 3% maximum error in dynamic (interval test) response and 5% error in static response of battery discharging (until 10% state of charge is left in the battery).
Keywords: Battery, look-up table, state of charge.
