Democratic Presidential hopeful Barack Obama has proposed a new ten-year $150 billion energy plan today in Michigan. A large part of the plan centers around transportation -- both the use of petroleum and the types of cars we are to drive in the future. For automakers, $4 billion in loans and loan guarantees would be made available for PHEV development, with one-million of the vehicles to be ready for sale by 2015. For consumers, a $7,000 tax credit would be offered for their purchase of said vehicle. Also, in a more short-term effort, Obama proposes that the U.S. sells some seventy-million barrels of oil from America's strategic petroleum reserve.

While those PHEVs are being developed, Obama's plan would increase fuel economy standards 4-percent per year. What's more, Obama would mandate at least 60 billion gallons of advanced biofuels by 2030 while requiring that fuel producers reduce their fuel's carbon emissions by 5 percent within 5 years and 10 percent within 10 years. To make those biofuels have as large an impact as possible, all new vehicles would be required to have flex-fuel capability within four years.

Lastly, the entire White House fleet will be converted to plug‐ins within one year (does this include the new presidential limo that will debut in January?) and half of all cars purchased by the federal government will be plug‐in hybrids or all‐electric by 2012. See the entire plan in .pdf form at this link.

Plug-In Supply has just released its new $4995 kit which converts your 2004-2008 Prius into a Plug-In Hybrid Vehicle (PHEV). Because the system is based on the Cal Cars reference design and uses lead-acid batteries as opposed to the more expensive lithium or nickel-based batteries, this new kit is cheaper than many other PHEV conversion options. According to Plug-In Supply, the kit will allow your Prius to operate in electric-only mode for up to fifteen miles and at speeds of up to fifty-two miles per hour. Getting 15 miles out of a lead acid pack will be a real stretch given that Toyota is only getting eight with a NiMH pack in its prototype PHEV Priuses. Getting a Prius up to 52 mph on batteries will also take a long time with the size of the electric motor used and all of this will absolutely, possitively void any warranty you may have left. The lead-acid batteries which help make this new kit relatively affordable aren't likely to last the life of the vehicle. Therefore, the pack has been designed to be upgradeable to lithium batteries in the future. Due to the 360-pound weight of the included battery pack, heavy-duty springs have also been made available for the rear of the Prius.

While it still may not make sound economic sense, this kit proves that the costs associated with creating PHEVs is going down. Those living in California, though, might be hard-pressed to purchase a kit such as this if CARB passes its new regulations, as kits using lead-acid batteries may find it rather difficult to meet some of the proposed requirements.

If the California Air Resources Board (CARB) passes the legislation that it is currently considering, getting your hands on a PHEV conversion, like the one recently created by Hymotion, might be a bit more difficult. Whether or not this is a bad thing depends on your point of view. Those looking to add a plug-in module to their Prius in order to use as little gas as possible might be paying a few more bucks for the conversion, as the pending legislation would force the manufacturer to go through the same rigorous certification process that new cars must pass. Of course, this could be an expensive proposition and could keep some contenders completely out of the market. The benefit, as some see it, would be that owners would be sure that their newly-converted plug-ins would meet all current emissions standards, something which may not necessarily be the case otherwise. Added peace-of-mind would come from forcing the manufacturers to offer a standard , something the legislation would also require. Another requirement which has seen some opposition is the mandate of a maximum four-hour charge time and a specific branded charger.

A row of Saturn Vue PHEVs in Milford's building 16 garage

GM may have been late to the party when it came to hybrids, but they are now throwing resources at a bunch of different parallel paths that including electric drive. There are already cars and CUVs with mild hybrid systems and full-size SUVs with Two-Mode hybrid systems. Later this fall pickup trucks and Saturn Vues will also get the Two-Mode system. Then there is of course the E-Flex Chevy Volt. Sometime around the end of 2009 GM's first plug-hybrid should debut also in the shape of the Vue. At the Plug-In 2008 conference Larry Nitz, the Executive Director of the hybrid powertrain engineering at GM provided an updated on the Vue PHEV program. After initiating development with nickel metal hydride batteries, the team based in Building 16 at the Milford proving ground now has 11 plug-in Vues running with lithium ion batteries. If the PHEV Vue makes it by the end of next year it will likely be the first commercially available plug-in hybrid from a major carmaker. The Vue is expected to have about 10 miles of electric driving range on a full charge.

At the Plug-In 2008 conference in San Jose CA this week General Motors will be on hand to announce a partnership with the Electric Power Research Institute (EPRI) to promote plug-in vehicles. GM VP for Global Program Management Jon Laukner will be delivering a keynote address at the Plug-in conference on Monday, and the EPRI partnership is expected to be part of the discussion. At this point GM doesn't have any production plug-in vehicles, but will debute two different models in the next two years. A plug-in version of the Saturn Vue Two-Mode hybrid is expected to debut in late 2009 while the Chevy Volt should appear a year later. The styling of the production car based on the Volt concept should be debuting in the next few months, possibly in September in conjunction with GM's centenial celebration. One possible key to the ultimate success of plug-in vehicles would be the installation of public charging stations allowing drivers to top up the battery as they go through their daily routines. Doing this will require the participation of local governments, businesses and electric utilities. Another factor that would help make plug-in vehicles financially viable for consumers would be the establishment of an aftermarket for lithium ion batteries that may not be useful for cars but could be used by utilities for buffering power supplies. EPRI previously announced a similar promotional partnership with Ford.

Michael Morris, Chairman and CEO of American Electric Power, believes that the U.S. electrical grid is capable of supporting up to 60 million plug-in hybrid vehicles right now. In a speech at the Detroit Economic Club, the chief of the biggest electricity supplier in the United States said that up to 20 percent of the U.S. vehicle fleet could be switched over to plug-in capability and the grid would be fine. Like other proponents of plug-in vehicles, Morris feels that PHEVs would actually help improve load balancing on the grid if they are plugged in during off-peak hours. Of course, getting the maximum benefit from this would require large numbers of plug-ins, as well as implementation of smart meters that could optimize charging during those off-peak times while limiting the load during the day. Such meters could also potentially support vehicle-to-grid technology. Ford is currently testing a plug-in version of the Escape hybrid with Southern California Edison while GM plans to introduce a plug-in version of the Saturn Vue 2-Mode hybrid in late 2009, followed by the Volt in 2010. Toyota will also start fleet tests of a plug-in Prius in 2010.

GM thinks that it has learned the lesson not to fall behind on technology and won't make that same mistake again. It's for this reason that the Volt is such a big deal for the automaker. Depending on how the next few years play out, though, we will either look back on Ford and realize just how smart the company was or just how deeply its head was stuck in the sand. It seems that Ford believes it has a solid position in hybrid technology and doesn't see an immediate need to be a leader in the development of a plug-in.

Instead, the Blue Oval is content to sit back and let cross-town rival GM and Toyota take the lead. In the meantime, Ford will continue to churn out hybrid versions of its Escape SUV and will introduce a new Fusion hybrid shortly. Hopefully, Ford will be able to play catch-up if the PHEV technology proves popular, otherwise, it could find itself in the same position as GM currently finds itself: as a technology-laggard.

By the middle of the next decade Mercedes-Benz wants its entire lineup to be able to operate entirely free of petroleum. The German giant is working on a variety of technologies that will help provide crude oil free transport such as battery electrics, fuel cells and highly efficient internal combustion engines that can operate on biofuels. Mercedes has recently been letting European journalists sample some of these new powertrains at a test facility in Spain.

The F700 concept that debuted last fall in Frankfurt is powered by a turbocharged DiesOtto engine. The DiesOtto is Mercedes' branding for a combined HCCI and spark ignition engine that provides nearly the same efficiency as a diesel without the need for the expensive after-treatment systems. This and conventional diesel engines can run on biofuels and Mercedes hopes to launch the DiesOtto in production by 2010. Mercedes is also currently field testing electrically-driven vehicles with both batteries alone and fuel cells each of which they also plan to launch at the beginning of the decade. While it may well be that all Mercedes models in 2015 will be capable of running petroleum free, the reality is that many - if not most - will still be using fossil fuels much of the time. That may come in the form of coal for electricity, natural gas reformed into hydrogen, or petroleum fuels blended with biofuels. But you have to start somewhere.

The first known instance of a plug-in hybrid car going up in flames occurred on June 7 in Columbia, South Carolina to a 2008 Prius that had been converted to plug-in capability for the Central Electric Power Cooperative. The conversion was performed with a Hybrids-Plus PHEV15 conversion kit that uses an A123 Systems lithium ion battery pack. The incident is still under investigation by Phoenix, Arizona-based Electric Transportation Engineering Corporation. Initial information indicates the fire may have been triggered by something related to the on-board battery charger and the car had previously experienced some mechanical issues related to that.

Unfortunately, the car didn't have a data logging system installed which might have helped to isolate the cause. No one was injured and the battery pack sustained some damage but was apparently intact and functional - implying that it was not the cause of the fire. What this points out is that before plug-in hybrids and EVs are brought to market a lot of engineering and validation testing needs to be done to ensure that all systems in the car are safe, durable and properly integrated. This is actually the part of vehicle development that often takes the most time. It's not just the batteries that have to work, but all the bits and pieces around it. That's why it's taking almost four years from concept to production for the Volt and why Toyota is in no rush to bring the PHEV Prius to market.

According to Ford's President of the Americas, Mark Fields, plug-in hybrid vehicles need to be a "national priority" and the United States government should be offering assistance for their development. Fields goes on to say that the governments of competing nations are funding the development of the technology needed to introduce PHEVs, especially batteries. As it stands, most hybrid batteries are produced in factories overseas by companies outside the U.S. If this trend continues, Fields suggests that a continued purchase of these batteries would merely be shifting our foreign dependence on oil to a foreign dependence on batteries. For this reason, the Ford executive calls on increased funding from Washington for high-tech batteries as well as tax breaks and incentives in order to give consumers additional reason to purchase the fuel-saving technology. We would think that high gas prices are effectively doing just that, but it is true that the tax breaks for hybrid vehicles may have contributed to some early sales.

Field's speech, which was made at the Plug-In Electric Vehicles 2008: What Role for Washington? conference on July 11, is a pretty interesting read, and you can find the entire thing pasted after the break.

So, we already know that Toyota will be showcasing its new third-generation Prius hybrid sedan at the upcoming Detroit Auto Show early in 2009. It's long been assumed that this new third-gen Prius would spawn a Lexus vehicle using the same platform and a similar hybrid system. Differences would include a higher price, obviously, and lithium ion batteries in place of the nickel metal hydrides installed in the Prius. What may be more interesting to some, though, is news that Toyota will also be displaying a third hybrid vehicle at the same show. Without giving away too many details, Masatami Takimoto, a VP in charge of research and development, indicates that this third hybrid will be a totally new car based on a larger platform than the current and next Prius. As has been widely reported, including on this very blog, Toyota's first plug-in hybrid is expected to debut in 2010.

In other green news, Toyota will be adding new gasoline-burning 1.3 liter and 2.5 liter engines along with stop/start technology, which is becoming increasingly popular in these days of high gasoline prices. Also on the docket is a new six speed manual transmission which will be kept compact for use in small cars. We look forward to seeing what else Toyota's got up its corporate sleeves.

While Toyota CEO Katsuaki Watanabe was in Tokyo talking up plans to start production of lithium ion batteries at the Panasonic EV Energy joint venture late next year, an American Toyota Exec was dampening expectations for the PHEVs in Washington. Bill Reinert, national manager of the Advanced Technology Group participated in a panel at the Google.org Plug-In Vehicle Conference. Reinert reiterated that while many plug-in proponents emphasize the potentential for 100mpg performance from PHEVs, not everyone will approach that.

Just as with current hybrid vehicles, the fuel efficiency of plug-ins will vary greatly depending on driving conditions. Reinert mentioned that acts like accelerating onto freeways and general real world driving will cut into the theoretical electric only range and the maximum mileage. This will be particularly true with so-called conversion PHEVs like the Prius, the Ford Escape and the upcoming Saturn Vue plug-in hybrid. These electric drive systems in these vehicles don't have sufficient power to propel the vehicle through the full spectrum of real world performance conditions. That means the engines will be starting up relatively frequently. Only when dedicated plug in vehicles with motors designed for full speed drive operation arrive will those kinds of mileage expectations be met more consistently. For more on this subject check out the interview we did with GM's Pete Savagian a few months ago.

The non-profit branch of the an obscure web-search company that goes by the name of Google.org has been investing in a lot of green technology over the last few years. Next week in Washington, D.C., Google.org is sponsoring a conference to discuss what the US government's role should be in promoting plug-in electric drive vehicles. The Brookings institution will be the co-sponsor for the event that begins on Wed. June 11. The event will include a series of panel discussions on various aspects of electric drive vehicles such as the current state of the vehicle technology, the effect on the grid, and federal policy towards EVs. Senators Orrin Hatch and John Kerry will both address the gathering at the Thursday morning breakfast. Mark Fields, Chelsea Sexton, Troy Clarke and Felix Kramer are among the participants. There should be some interesting discussions going on, particularly considering that Congress is currently considering tax credits for plug-in hybrid vehicles.

Enova Systems has been collaborating with IC Bus for the past couple of years to build a series of plug-in hybrid school buses for testing purposes. Enova recently had an independent CARB-certified lab conduct dynamometer tests on a pair of PHEV school buses to compare the fuel consumption and emissions against conventional models. Enova's system is designed to be installed downstream of the transmission so that it can be easily adapted to buses and drivetrains from different manufacturers. One 2007 and one 2008 IC Bus Series CE bus with different engines and transmissions were tested on a West Virginia University Suburban Test Cycle designed to emulate a typical school bus duty cycle. In the tests, the PHEV buses saw a 70 percent reduction in diesel fuel consumption. Carbon dioxide emissions were cut by 40 percent while soot and NOx were reduced by 30 and 20 percent, respectively. IC Bus has also decided to cut the $200,000+ of the hybrid buses by $40,000. Currently there are 19 of the Enova equipped buses running in eleven states.

EnerDel's lithium-titanate battery has been independently tested by the Center for Transportation Research of the
Illinois-based Argonne National Laboratory. For the tests, a stock Toyota Prius had its nickel metal hydride battery pack replaced with a new 1kWh lithium ion unit from EnerDel. No problems were reported, despite the fact that no additional cooling modifications were made to the vehicle or battery pack. Additionally, a test was run which was intended to predict what the battery pack would be capable of if the Prius were converted to a Plug-In Hybrid Electric Vehicle (PHEV). Test results were promising, with the EnerDel-equipped Prius achieving 77.41 miles per gallon on the city test. Although these results are just an approximation of what a PHEV Prius could offer, they are still promising. Also of note is the fact that internal resistance of the pack was reduced by sixty-seven percent over the stock Prius pack.

According to the press release pasted after the break, EnerDel's pack could be half the size of the Prius' stock pack while still offering the same performance, meaning that a similar-sized pack as stock would offer twice the power potential. Thanks for the tip, Jan!
