Abstract

The battery/ultracapacitors (UCs) integration is able to provide notable advantages in the power management of an electric vehicle (EV), in terms of capability of both high energy storage and readiness to deal with fast load variations. In order to manage the charge (or discharge) of the UCs from (or towards) a DC voltage bus, a proper bi-directional converter is required. In this paper, a bi-directional DC-DC converter in connection with a stack of UCs is described and some power simulation results are provided. The proposed converter is a B2R (buck-boost regulator) type. The load is represented by a 40kW peak power, kept for a time window of 3s, as required by the Worldwide harmonized Light vehicles Test Procedure (WLTP).
