Electrical vehicle feeding by association of utltracapacitors and photovoltaic generators

Abstract : the aim of this work is to study the association of the ultracapacitors and photovoltaic generators to feed an electrical vehicle. In order to size these components, two electrical models have been proposed starting from their physical behaviours. Two DC-DC converters for the energy management between the photovoltaic generator, the ultracapacitors and the dc bus of the electrical vehicle, have been proposed. The simulation of their functionalities gives good results and shows the possibility to achieve this new application.
