Abstract

International audience; This paper presents a study which follows the present trend in the field of electric (or hybrid) vehicles E(H)V, having in mind that the major drawback of these last ones is the autonomy problem. Thus, by using a hybrid energy source (formed by ultracapacitors and battery) and with a proper current control (of polynomial type) one can get a good energy management which will increase the lifetime of the battery. Through numerical simulations and tests at reduced scale, the authors present a successfully energy management on board of a hybrid vehicle.
