Ford's test program for the Escape plug-in hybrid is expanding beyond the original partnership with Southern California Edison (SCE). The Electric Power Research Institute (EPRI) will join the program, setting up a group of utilities in the New York-New Jersey area that will also participate in the test program of the twenty PHEV Escapes that Ford is building. The Escapes will initially be tested in California by SCE after which the fleet will be shared with the EPRI group.

The expanded test program will help increase the understanding of the potential impact of plug-in hybrid vehicles on the electrical grid. Including northeastern states in the testing will allow the evaluation of the impact in different regions and weather conditions. The collaboration among utilities in different areas should help them to standardize what kinds of accommodations need to be made to the grid and power generation systems to accommodate larger numbers of plug-in vehicles. More after the break.

• 95 years for a PHEV conversion to pay for itself in gas savings?

Last year, Google made some waves when they announced the RechargeIT project to convert a fleet of Toyota Priuses and Ford Escape hybrids to plug-in capability. The company has just issued their first progress report on the program, and the results may be disappointing for those promoting plug-in conversions. Right now the only way to get a plug-in hybrid is to buy an off-the shelf model like the Prius or Escape and than install a $10-15,000 conversion kit. Unfortunately, as we learned from a recent interview with GM's Pete Savagian, a conversion PHEV provides a limited additional benefit over a conventional parallel hybrid because the motors typically don't have enough power to drive the vehicle under most conditions without the engine turning on.

The other issue is that as fuel efficiency increases, the incremental savings in fuel use actually decrease. This is more apparent if you use the European units of fuel consumption which is measured in L/100km. If consumption is reduced from 12L/100km (19.6mpg) to 6L/100km (39.2mpg) you would save 6L on a 100km trip. Doubling mileage again going to 3L/100km (78.2mpg) only saves an additional 3L. This is apparent when you take an already efficient car like the Prius which starts at 44.6mpg and increase it to the 66.2mpg that Google saw. The result over 12,000 miles of annual driving is 88 gallons of fuel saved. At $3/gal, that's $158/year (after factoring in electricity costs). At that rate the $15,000 conversion would take 95 years to recover the cost. Ouch.

Google points out that most of the driving was on short runs where the engine often runs early in the drive to power certain vehicle subsystems. Longer runs would increase the mileage further, but you still have the issue of diminishing returns. With gas at $5/gal and a conversion cost of $10,000, the payback drops to a mere thirty years. Until vehicles are actually engineered from the ground up as PHEVs and mass produced to bring down cost, the cost benefits simply won't be realized by people doing conversions. Reduced emissions and oil use, though, should still take place.

Smartlets. Sounds like a new, electrolyte-filled candy or something you plug into your MacBook. Instead, Smartlets are one idea that would provide power to plug-in electric vehicles like the Chevy Volt or the Saturn Vue.
Partners Richard Lowenthal, CEO of California-based Coulomb Technologies, and Praveen Mandal will describe Smartlets to attendees of the Plug-In Car show in San Jose, California this July. According to Automotive News, Loenthal envisions Smartlets available for EVs and PHEVs in urban areas where people normally park their cars: parking lots, offices, stores, etc. Of course, Smartlet-like chargers are already available (for free) in some areas, like London.

GM likes the idea, but is taking a hands-off approach, but GM's vice president of global program management. Jon Lauckner, told Lowenthal and Mandal last fall that Smartlets are "a good idea." Of course, even though the Vue and the Volt are likely to be among the first plug-in vehicles available from a large automaker, Smarlets would probably be compatible with many plug-in vehicles, at least those that use a standard plug and can accept 110 or 220 volts. We'll need a wait a while to here more about Smartets. The Coulomb Technologies website says the company "is currently in quiet mode."
