| Abstract |
In electric vehicles, peaks power during acceleration or overtaking phases are hard constraints for batteries. The avaibility of a new type of electric capacitors, called ultracapacitors,
as a power auxiliary source, both enables to improve some performances of electric vehicle and
to reduce the constraints on the batteries. In this paper, the authors compare two network structures
to use such ultracapacitors and show that a serial structure brings more advantages than a parallel one. Then, they discuss how to determine the required size of such a capacitor used as an auxiliary power device. Finally, thanks to simulation software system EASY SX(l), simulations results are
presented in order to quantify the performance of a electric vehicle with a such auxiliary power source. |
