Simulations of Plug-in Hybrid Vehicles Using Advanced Lithium Batteries and Ultracapacitors on Various Driving Cycles

This paper is concerned with the application of the 2-energy storage models to plug-in hybrid vehicles (PHEV) using advanced lithium batteries having energy densities of 200-400 Wh/kg. These high energy density batteries often do not have commensurate high power capability and thus will benefit greatly by being combined with ultracapacitors or other very high power capability devices. This is especially true of PHEV designs which are intended for all-electric operation in the charge depleting mode. Simulation results are presented for mid-size PHEVs with all-electric ranges of 25-90 km. It is shown that high energy density, relatively low power batteries combined with ultracapacitors will provide good all-electric vehicle performance with much reduced stress on the batteries. This is expected to significantly enhance battery cycle life.
