CONCLUSIONA compact thermal modelling of Electric Double-Layer-Capacitors has been presented. Compact models are suitablefor determining static and dynamic temperature undercycling, at any point of the components, as a function oftopology, materials properties, and operating conditions.Thermal circuits have been created by combining differentbranches of Multi-Ports Matrix Elements referring to eachdirection of heat transport. Circuits were developed byconsidering a uniform volume heat generation and, for eachbranch, a one-directional thermal transport. Performance ofthe compact modelling has been investigated in terms ofaccuracy and computational cost. It was found a goodagreement with simulations by the Finite-Elements Method.Deviation in temperature did not exceed 8 %. Compactthermal models can be suitable for most of energy storagedevices such as capacitors and rechargeable batteries.REFERENCES[1] Chu A., Braatz P., « Comparison of commercial supercapacitorsand high power lithium ion batteries for power-assist applications inhybrid electric vehicles I.
