SuperLIB Project - Analysis of the performances of the hybrid lithium HE-HP architecture for plug-in hybrid electric vehicles

This paper represents the latest results of the FP7 European Project SuperLIB: Advanced Dual-Cell Battery Concept for Battery Electric Vehicles. The electrical characteristics of the proposed hybrid topology based on high power and high-energy cells are presented. In the framework of project, dedicated research work has been carried out in the field of characterization and modeling. From these characterization results advanced simulation models have been developed for investigation and prediction of the proposed hybrid concept in detail based on innovative simulation tool for evaluation and optimization of the power flow in the driveline. From the simulation results have been concluded that the performances of the vehicle can be enhanced in terms of power capabilities and range extension. Then, the results also show that the abilities of the high-energy battery can be improved in terms of energy efficiency, voltage drop and heat development inside the battery. Finally the comparative analysis illustrates that the SuperLIB hybrid architecture has several merits against the hybrid topology based on high-energy batteries and electrical double-layer capacitors in terms of weight and volume.
