Hot on the heels of the announcement that Mercedes will produce electric cars, comes the news that fellow German manufacturer Volkswagen plans to produce a test fleet of plug-in hybrid electric cars by 2010.

A few months ago, to much excitement from the automotive press, the company unveiled a diesel-electric Golf but, according to VW chief Martin Winterkorn, “the future belongs to electric cars.” To help in mapping out the road to this electric future, the company have unveiled a plug-in hybrid powertrain, called the Twin-Drive, which will make its first appearance in a Golf kitted out with a 122-horsepower diesel engine, twinned with an 82-horsepower electric motor.

Vacuum Cleaner Whiz Going To The Streets

Update: Dyson Is NOT Making An Electric Car, A Report from London

The king of vacuum cleaners, James Dyson, is betting that a souped-up version of his vacuum cleaner and hair dryer motors will power cars over hundreds of miles.

Using technology developed for his lightweight electric motors, Dyson hopes to partner with Honda or another car maker, rather than build a car from the ground up.

Solar panels on top of the vehicle, or on the garage where it is stored, would provide electricity to charge the car’s battery.  Of course, the best performance would probably come from a country where there’s abundant enough sunshine to keep the battery charged.

Of course, he could also think about adding a plug-in function, just in case it stays cloudy for days on end. Read the rest of this entry »

On his campaign swing through the west, Sen. John McCain proposes awarding $300 million to the first developer of a battery technology that exceeds all known technology today.  The package would have to be superior to any technology known today, to power plug-in hybrids or electric cars.

McCain is also focusing on alternative fuels, suggesting a $5,000 tax credit for every person who buys a zero-emission vehicle.  He says that should level “the playing field for all alcohol fuels that break the monopoly of gasoline”. Read the rest of this entry »

First Flex-Fuel Plug-in Hybrid Electric Vehicle

As part of a push by the US Department of Energy (DOE) to make plug-in hybrid electric vehicles (PHEVs) cost competitive with other cars by 2014, Ford has delivered a plug-in hybrid electric flex-fuel Escape to the DOE to join its test fleet of other PHEVs currently undergoing research and testing.

The vehicle is equipped with a 10 kilowatt lithium ion battery that can take it up to 30 miles at speeds under 40 mph before needing to fire up its fuel-fed hybrid-electric engine. After that, the hybrid-electric engine kicks in and can deliver a fuel economy of 88 mpg in the city and 50 mpg on the highway when using E85 (85% ethanol/15% gasoline blend).

UC Davis’s Institute of Transportation Studies has prepared a sort of primer for “non-battery experts” on the pros and cons of different battery technology for use in plug-in hybrid electric cars (PHEVs). The report, called Batteries for Plug-in Hybrid Electric Vehicles (PHEVs): Goals and the State of Technology circa 2008, discusses:

• the basic design concept of PHEVs and inherent trade-offs in different battery technology.
• the current state of the most common battery chemistries, including nickel-metal hydride (NiMH) and lithium-ion (Li-Ion), and their abilities to meet the needs of PHEVs
• potential trajectories for further improvement in battery technology Read the rest of this entry »

It had to happen, just when we were beginning to think that plug-in hybrid and electric cars were the best things since sliced bread, someone has intimated that there may be a health risk involved in driving those vehicles.

You remember, the power line scare back in the ’70’s (which really hasn’t gone away) and of course the more recent flap about cell phones emitting dangerous electromagnetic fields to the brain. In case you want to read more on these issues, a specific Google entry should suffice.Now, before you go somewhere else, hang on, there’s more to this electromagnetic field issue than you may think. That’s coming up, along with a short tip of the hat to the man who got us started on our way to the world we live in. Read the rest of this entry »

As Benjamin reported on EcoGeek last week, even if all plug-in hybrid electric vehicles (PHEVs) were recharged by coal-based electricity, they would still be an improvement over regular cars. Take a look at this graph from Technology Review, who reported that “plug-ins always result in lower emissions than conventional cars.” They beat hybrids too, unless power is coming exclusively from coal:

Recently, I discussed the interaction between clean energy and the future of plug-in hybrid electric vehicles (PHEVs). The study cited makes it clear that unless we clean up power production, there isn’t much point in moving to PHEVs from regular, old hybrids (HEVs).

Interestingly enough, MIT has just come out with a new study, profiled by Green Car Congress, which studies all sorts of vehicle options and how each vehicle will perform in well-to-wheel greenhouse-gas (GHG) emissions. This study was done particularly on HEVs, PHEVs, battery electric vehicles (BEVs), and fuel-cell vehicles (FCVs). The MIT researchers came to the conclusion that ultimately, electric propulsion in automobiles could eliminate our dependence on petroleum, which to me sounds like an exciting prospect, regardless of GHG emissions.

GM’s plug-in hybrid electric car, the Chevy Volt, will have its lithium-ion batteries road-tested by end of the month. Engineers have already been testing the Volt’s electrical hybrid system, the so-called E-Flex architecture, but only with nickel-metal hydride hybrid batteries in place. The newer, more advanced lithium-ion batteries are seen as the key to to the vehicle, since they store energy more efficiently than other batteries of the same size.

Last week, GM engineers worked to replace the nickel-metal hydride batteries with lithium-ion batteries in three different test-vehicle “mules”. These trial vehicles have allowed engineers to fine tune and improve components of the vehicle system, before putting it all together into something that more closely resembles the final Volt production model. GM hopes to complete road-testing for the Volt by November 2010.

This is something I (and a lot of other people) have been wondering about for a while in regards to plug-in electric vehicles (PHEVs, like the Chevy Volt) and pure electric vehicles (EVs, like the Lightning GT and Subaru R1e). PHEVs are not a new thing, and they have been discussed on Gas2.0 before, but there is some interesting news that recently came out of Carnegie Mellon University suggesting that if we don’t make our power generation system less carbon intensive, PHEVs could have little benefit over regular hybrids (HEVs).
