In this paper, different modeling approaches representing the behavior of supercapacitors are presented. A hybrid modeling approach is developed to improve the characterization of classical supercapacitor models proposed in the literature. This approach uses various representations (frequency and temporal results) of the same cycling test to extract easily(More)
Two issues are still a great challenge in design and application of advanced controlled electric drives: 1) recovery of the braking energy and 2) ride-through capability of the drive system. Apart from ordinary solutions, such as back-to-back and matrix converters, the ordinary drive converter equipped with an energy storage element is used in specific(More)
The association of more than one storage system to ensure the supplying of the hybrid and electric vehicle became more and more useful by the cars manufacturers. The asked question in this case is the optimal amount of the deferent energy sources to ensure the mission with the best lifetime. The first parameter witch influence the architecture of the hybrid(More)
Combining a high-power source like a supercapacitor with a lithium-ion battery for electric vehicle applications results in performance improvements, high efficiency, long lifetime, lightweight design, and relatively modest cost of the overall source. A hybrid energy storage system controlled by a smart energy management strategy can play a key role in the(More)
For hybrid and electric vehicle, high powers are needed for the acceleration, startup and recovery phases. For that, the chosen storage system must insure these high powers. The supercapacitors are powerful storage systems, which can reach more than 4,3kW/kg of specific power, and very high lifetime compared to the other storage components. Until 1957 five(More)
