摘要

Plug-in Hybrid Electric Vehicles (PHEVs) have the ability to drastically reduce petroleum use. The FreedomCAR Office of Vehicle Technology is developing a program to study the potential of the technology. The first step in the program is to define the requirements of PHEV components. Because the battery appears to be the main technical barrier, from both performance and cost perspectives, research has focused on that component. Working with FreedomCAR energy storage and vehicle experts, Argonne National Laboratory (Argonne) researchers have developed a process to define the requirements of energy storage systems for plug-in applications. This paper describes the impact of All Electric Range (AER), drive cycle, and control strategy on battery requirements. First, battery requirements are defined for several vehicle classes and AER by using a vehicle simulation tool. Then, a subset of the simulation is validated by using the Li-ion JohnsonControlSaft VL41M using battery Hardware-in-the-Loop (HIL). Finally, the simulated requirements, based on following the Urban Dynamometer Driving Schedule (UDDS), are compared with an aftermarket Toyota Prius tested on a dynamometer at Argonne's Advanced Powertrain Research Facility (APRF).
