New Kits Turn Any Car Into a Plug-in Hybrid(see News on Yahoo Homepage 12.6.2008)

Even Toyota Prius owners are cringing at today’s gas prices. New conversion kits offer the potential for 100 miles per gallon and more.

Soon drivers will be able to get at least double the gas mileage of a Toyota Prius hybrid, thanks to a spate of new aftermarket kits that convert any car into a plug-in electric vehicle. But they’ll have to pay upwards of $10,000 to do so.

Auto manufacturers are at least a year or two away from launching the next generation of hybrids, called plug-in hybrid electric vehicles (PHEVs), that recharge by plugging into a wall outlet. But battery companies are ready to start selling aftermarket kits within the next few months that convert hybrids, and in some cases regular vehicles, into plug-in electric cars.

A123Systems, an automotive technology company and battery supplier based in Watertown, Mass., is now taking orders for its Hymotion L5 conversion kit, which turns a Toyota Prius into a plug-in electric car. The $10,000 kit, due this fall, works with Prius model years 2004 through 2008 and adds a special, range-extending lithium-ion battery to the Prius’ existing drivetrain.

Using A123’s plug-in system, the Prius, which normally runs only short distances at slow speeds on electric power alone, will have added battery power to extend its electric-only range and boost gas mileage to more than 100 miles per gallon. The Prius normally gets an estimated 46 mpg in combined city/highway driving.

Even if electricity costs as much as 15 cents per kilowatt hour, fully charging the 5 kilowatt-hour battery to run up to 40 miles would cost less than a dollar.

In late August, Poulsen Hybrid, based in Shelton, Conn., and run by Ulrik Poulsen, CEO of Bridgeport Magnetics, plans to offer a $7,000 conversion kit that turns any conventional car into a plug-in hybrid electric vehicle by mounting small electric motors onto the rear wheels. The Poulsen system also uses a lithium-ion battery pack and will double a car’s gas mileage, says Poulsen, the system’s creator. The company hasn’t released data on how far the system will go on a single charge, but charging it would also cost less than a dollar, he says.

VS Composites’ $4,000 Electrocharger, due in 2009, also works with any conventional car, including ones whose engines have a turbocharger or supercharger — good news for car enthusiasts, who seek out such engines for the added power and acceleration they bring. The Electrocharger improves fuel economy in city driving by almost 60 percent by replacing a vehicle’s alternator with an electric generator, says Michael Van Steenburg, of VS Composites, based in Selma, Texas. Although the Electrocharger will be cheaper upfront than the Poulsen plug-in hybrid system, it will cost from $3 to $5 to juice the Electrocharger for a 50-mile range.

Any plug-in hybrid, whether created using an aftermarket conversion kit or built by a major automaker — like General Motors’ Saturn Vue Hybrid expected for 2009, and Chevrolet Volt expected in 2010 — would cost roughly 2 cents per mile to run, compared with about 10 cents per mile for a traditional car, says Philip Gott, director of automotive consulting at research firm Global Insight.

It would take 8 years to pay off the $10,000 premium of an electric system driving 40 miles a day and saving 8 cents per mile, Gott says, which is longer than most people want to own a car. “But people buy these things to make an environmental statement,” he says.

One concern for the conversion kits is their reliability and whether they would void a vehicle’s original factory warranty. In this regard, plug-in hybrids built by automakers are a safer bet than conversion kits, Gott says. “Typically, kits don’t have a national service and infrastructure.”

Toyota, which has announced plans to bring plug-in electric vehicles to market by 2010, is skeptical of the conversion kits. “While A123’s test results sound encouraging, we are still concerned that a conversion of this type may push some components beyond their design parameters or cause other parts or systems to fail,” says Bill Kwong, a Toyota spokesperson. “We don’t know if occupant safety may be compromised by the modifications.”

Auto analyst Art Spinella, of CNW Marketing Research in Bandon, Ore., expects half of the aftermarket plug-in electric conversion kits will have problems. “And it’s not so much the hardware that makes it expensive, it’s the complexity,” he says. “We really don’t know yet all the ramifications of plug-in hybrids. At this point, for the most part, plug-in hybrids are nothing more than a curiosity for most consumers.”

That said, Spinella expects the cost of plug-in hybrid technology, whether as part of aftermarket conversion kits or factory-original vehicles, to go down in a few years. “Look at the computer industry. Now you can get a computer for $349 that used to cost $3,000,” he says. “Initially, the market is going to wind up being early adopters — people who will buy a plug-in conversion kit because it’s the latest and greatest.”

But whether you choose to buy a plug-in hybrid straight from an automaker in a couple of years or opt for a plug-in conversion kit this fall, certain benefits are guaranteed. “You’re diverting your energy demand to that produced by a centralized facility monitored for emissions or performance, as opposed to a regular car that owners don’t necessarily maintain as well,” says Global Insight’s Gott. “The electric power grid’s energy comes from coal, nuclear, wind, hydro and solar energy.”

By relying on electricity from a power plant rather than gasoline from a pump, “within a more reasonable time frame, you will continue to be upgraded to the most modern fuel technologies,” Gott says.

  1. […] Sebenarnya teknologi ini sudah tiba, sudah ada pengeluar kereta seperti HONDA, TOYOTA dan lainnya di Barat telah menggunakan teknologi dalam hybrid car mereka, tetapi seperti yang dibuat oleh ‘the rich filty’ ni, mereka mahu jual keretanya sekali, jadi tak heran lah jika harganya tak mampu oleh orang orang seperti kita.
