ELECTRIMACS 2017, TOULOUSE, FRANCE, 04-/07/2017 - 06/07/2017. Batteries have been associated with supercapacitors in some vehicle applications. This has been done to face the batteries limitations in terms of power transfers and lifetime. This paper deals with a comparison between two battery/supercapacitors architectures. The first architecture consists in using a DC-DC converter as an interface for the supercapacitors. In the second architecture two DC-DC converters are used, one for each source. The energy management of the two vehicles is first performed. The two vehicles are then compared by simulation tests on a normalized driving cycle. The results show that the performances are equivalent in terms of battery lifetime.
