This paper presents the control design of a multilevel modular DC/DC converter for regenerative braking systems in mobile applications. The proposed control scheme is able to control the energy flow between supercapacitors and the DC link and equalizing th ...
This work proposes a design methodology that allows designing the energy storage unit of an electric vehicle in order to minimize the required energy and the resulting losses. A simple analytical model of the vehicle losses is derived. Driving conditions a ...
Multi-walled carbon nanotubes functionalized by carboxylic groups, exhibit better affinity towards TiO2 (P90, Degussa) as compared to that of pristine nanotubes. Also the electrochemical performance of TiO2 is improved by nanotube networking, but the Li-st ...
A new thermal model, which allows temperature distribution determination inside a supercapacitor cell, is developed. The model is tested for a supercapacitor based on the activated carbon and organic electrolyte technology. In hybrid vehicle applications, ...
The tribological behavior of well-aligned carbon nanotube (CNT)/alumina nanocomposites was studied at multiple length scales. Pin-on-disk, microscratch and atomic force microscopy were used to test three nanomaterials: alumina matrix, thin-walled and thick ...
A storage supercapacitor subsystem is studied for insertion in a series hybrid electric vehicle (Fig. 1). This subsystem is composed of a supercapacitor bank and a braking resistor used when the supercapacitor voltage is at its maximum value. Generally, wh ...
