Abstract :
This paper presents a study on the ultracapacitors dynamic behaviour. Frequency analysis is chosen as the tool to perform this investigation. First, the impedance spectroscopy principles are presented. Then the experimental results, obtained by applying impedance spectroscopy with high current levels, are presented and discussed. Ultracapacitors show a particular behaviour which leads to it specific model composed by a small serial inductance associated with a four RC-branches network.
