PHIL Simulation of a Parallel HEV Equipped with Different Energy Storage Systems
Authors: , , ,
Abstract: Simulation has been acknowledged as an effective method of optimizing fuel consumption and sizing components for hybrid electric vehicles (HEVs). However, the accuracy of simulation results requires validation. Power-hardware-in-the-loop (PHIL) simulation can be an effective technique in obtaining accurate results and comparing different options before prototyping. Using the PHIL concept, this paper presents an implementation of a parallel HEV architecture on a dynamometer power train system. Four different energy storage systems (ESSs) in the HEV were tested to compare the performance of each system. The four ESSs included the battery-only type and the battery/ultra capacitor-based hybrid type. A fuzzy logic energy management strategy was implemented to address the power distribution in the HEV. In this paper, we compare and discuss the energy efficiency, electrical performance of the ESSs, and fuel economy of the HEV. The results show that hybrid ESSs have several advantages over the battery-only systems.
