Recent developments make appear new devices for energy storage, such as supercapacitors. Those components are able to store a high energy density. Even if this energy is still lower than the energy batteries can store, thos components can be loaded and/or ...
Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low. But, as power sources they have the property to be re-loadable in a few seconds [1][2][3]. In that case, the needed ins ...
Supercapacitors are new components ale to store a high energy density aven if this energy is still lower than the energy batteries can store. This paper shows how supercapacitors can be used to supply electric vehicle such as busses and tramways. The "on-b ...
Recent progresses in the technology of the Ni-Zn batteries have a direct influence on the improvement of the performance of hybrid electric vehicles. This paper evaluates the progresses of these batteries in particular for application on hybrid light vehic ...
Diesel-electric traction is a well-established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel-powered locomotive is due to the reduced costs compared to the infrastructure cost of ...
The simulation of a series HEV (hybrid electric vehicle) is suggested by using the Energetic Macroscopic Representation (EMR). Simplified models are used in a first step. They lead to the simulation of an overall HEV with its control. The system is decompo ...
Vehicle drivetrains are complex integrated systems, which need to be designed for numerous thermodynamic, economic and environmental factors. As part of a project of the Alliance for Global Sustainability between the MIT, the SFITs and the University of To ...
