Abstract

This paper presents an embedded energy share method between the high energy storage system (battery) and the auxiliary energy storage system such as supercapacitors (SC). Using the SC and battery with a good strategy for energy management improves the performance of hybrid electric vehicles (HEVs). The SC modules are dimensioned for peak power requirement, and the battery's module ensures the average power of HEVs. The battery module is connected to dc-bus through a dc/dc converter for the first topology and without a converter for the second configuration. Buck-boost converters are used between the SC and the dc-bus to manage the available energy for all topologies. The originality of this paper stems from its focus on the control methods of the dc-bus voltage and currents, which use adjustable polynomial controllers (correctors based on polynomial approach). These methods are implemented in the PIC18F4431 microcontroller which ensures analog to digital conversion, and the pulsewidth modulation signals generation for dc/dc converters. Due to cost and available components, such as the power semiconductors (IGBT) and the battery, the experimental tests benches are carried out in reduced scale. Through some simulations and experimental results, the performance of the proposed control is shown and analyzed. [ABSTRACT FROM AUTHOR]

Abstract

International audience; This paper presents a comparative study between the frequency approach and dynamic component method for energy management in Hybrid Electric Vehicles (HEVs). An auxiliary energy system based on ultracapacitors (U), and the High Energy Storage system focused on lithium-battery are used to share the requested energy by a vehicle. Ultracapacitors are linked to DC-bus through a bidirectional converter, and the lithium-battery is directly linked to DC-bus without a converter. An inverter and Electrical Machine (EM) are used to emulate the energetic demand of the Hybrid Electric Vehicle (HEV). The contribution of this paper is focused on a HEV power sharing between the ultracapacitors and the battery according to the dynamic responses of the sources. The performances of the proposed methods are evaluated through some simulations and experimental tests using United States drive cycle.
