Abstract
This paper presents a new strategy of embedded energy management between battery and supercapacitors (SC) for hybrid electric vehicles (HEV) applications. This proposal is due to the present trend in the field, knowing that the major drawback of the HEV is the autonomy problem. Thus, using supercapacitors and battery with a good energy management improves the HEV performances. The main contribution of this paper is focused on DC-bus voltage and currents control strategies based on polynomial controller. These strategies are implemented in PIC18F4431 microcontroller for DC/DC converters control. Due to reasons of cost and available components (no optimized), such as the battery and power semiconductors (IGBT), the experimental tests are carried out in reduced scale (2.7 kW). Through some simulations and experimental results obtained in reduced scale, the authors present an improved energy management strategy for HEV.
