CMU study explores optimizing PHEV design and allocation to minimize life cycle cost, petroleum consumption, and GHG emissions

Green Car Congress

Jeremy Michalek and colleagues found that while a fleet with plug-in hybrid electric vehicles (PHEVs) with universal high electric range (i.e., 87 miles all electric) minimizes petroleum consumption, minimum lifecycle greenhouse gas (GHG) emissions are achieved with a mix of low-range (~25 miles) and mid-range (40-50 miles) PHEVs.

Mixed Outlook for Mainstream Consumer Adoption of PHEVs

Green Car Congress

Bubble chart of plausible mainstream PHEV buyers’ battery requirements (light and dark gray circles) and experts’s requirements overlaid on a Ragone plot of NiMH and Li-ion batteries. Questions for the industry, Kurani said, include how do we get from where households currently are to where PHEVs provide the most benefit?

ORNL, UT Austin team proposes optimization framework for hybrids; balancing fuel consumption, motor efficiency, battery capacity and life

Green Car Congress

Researchers at Oak Ridge National Laboratory and the University of Texas at Austin have developed an optimization framework for hybrid-electric and plug-in hybrid-electric vehicles (HEVs and PHEVs) including fuel consumption, motor efficiency, and battery capacity and lifetime.

The 80-20 Rule

Plug In Partners

O ften when I talk about Plug-Ins , I say that PHEV's are a perfect embodiment of the 80-20 rule. But in the case of the PHEV , the logic goes something like this: Roughly 80% of our daily trips are under 35 miles. Take care of that 20% with a small, efficient gasoline engine that runs at its optimum speed. 2) The U.S.

Near-Term Prospects for Automotive Li-ion Batteries: 21% of Hybrid and EV Market by 2011

Green Car Congress

Anderman ran a series of net present value analyses based on a range of gasoline prices, fuel saved, and pack costs. On a 5-year NPV analysis of fuel savings, he found that: Micro hybrids makes economic sense for the consumer on a fuel savings basis when gasoline is at $5/gallon US. PHEVs and EREVs require $7/gallon.
