This paper reports on the electro-thermal modelling of a Maxwell supercapacitor (SC), model BMOD0083
with a rated capacitance of 83 F and rated voltage of 48 V. One electrical equivalent circuit was used to
model the electrical behaviour whilst another served to simulate the thermal behaviour. The models
were designed to predict the SC operating voltage and temperature, by taking the electric current and
ambient temperature as input variables. A five-stage iterative method, applied to three experiments,
served to obtain the parameter values for each model. The models were implemented in MATLABSimulink , where they interacted to reciprocally provide information. These models were then validated
through a number of tests, subjecting the SC to different current and frequency profiles. These tests
included the validation of a bank of supercapacitors integrated into an electric microgrid, in a real
operating environment. Satisfactory results were obtained from the electric and thermal models, with
RMSE values of less than 0.65 V in all validations. [--]
