Résumé

To develop electrical busses for applications with a fast recharge system in stations, PVI has been testing some electrical energy components like supercapacitors and batteries with high power density. Nevertheless, supercapacitors limit average autonomy between two recharge points, due to their poor energy density. On the other side cycle life of batteries are very dependent on current. To surmount these problems, PVI in collaboration with the FCLAB laboratory and the AMPERE laboratory, are studying Lithium-ion capacitor (LIC) for applications with fast recharge. We take to assess how the storage system meets busses power and energy requirements in heavy electric vehicles. We note that the advantage of LIC technology compared to conventional supercapacitor lies in the fact that the energy density and the nominal voltage are higher. In this study, the Li-ion capacitor is characterized and modelled. The characterization and modelling methods are the same of supercapacitor with double layer activated carbon technology. The LIC efficiency will be discussed.
