Should we be thinking about standardized everything for plug-in vehicles?

Filed under: , , ,

AutoblogGreen reader Michael V. is worried. With all of the work being done on plug-in vehicles by automakers large and small, he thinks a slew of propriety batteries, chargers and plugs will effectively kill (well, at least hurt) the widespread adoption of plug-in vehicles. Instead of just worrying, though, Michael wrote an open letter to the auto industry, which he sent to us and we've pasted after the jump, about this issue.

While Michael is certainly onto something with the thought that incompatible plugs could pose a problem for, say, GM-Ford families (for example), he's missing one detail. The beauty of a plug-in system is that we don't need to come up with a new standardized plug agreement; there already is a standard plug. Whatever device you're reading this post on uses it. The issue, though, is the high-speed chargers (like the one from Tesla Motors, pictured), which are not standardized. Considering the complexity of these systems - and the simple fact that there is so much potential variety in battery types and chemistry and sizes that PHEVs and BEVs can use - calling for a standard at this point seems quixotic, to say the least. A good idea, and certainly customer friendly, but perhaps something to keep on the back burner for now. Let's get these vehicles on the road first. They will have a "standard" plug from day one, and we can all live with that.

Michael's letter (minor typos edited:

An open letter to the auto industry,

I have seen lots of articles about just about every auto maker having plans for plug-in hybrid or all electric vehicles. I think this is great I am 100% supportive of shifting some or all of the burden of producing energy for transportation away from gasoline.

One huge request though, please act soon to create and adopt an industry-wide standard for power supplies, plugs, and battery packs. I am a software developer and follow developments in the computer industry closely. I know that standards for interfaces like this can take years to be developed and agreed upon between all parties, much less come to market. It disturbs me that I haven't heard anything about this crucial step to implementation.

I'm sure you have experienced what a clusterf**k it is to change cell phones, laptops, or other gadgets. Every phone has a different plug and every time you change phone's you need to buy new accessories like different car chargers for the plug and whenever you travel you have to bring the charger with you.

There will never be infrastructure to support remote "refueling/charging" if there is no standard. People without enough garage space will not be able to charge their car outside if they have to leave a power supply, which might cost hundreds or thousands of dollars, outside and vulnerable to theft. Building the power supply/inverter into the vehicle might be possible but it may add weight and should still have a standardized interface to keep costs low since it will probably represent a relatively high failure rate, consistent with other electronic equipment. I don't want to go to visit my parents house and not be able to plug-in at their place because we drive different cars.

No one would drive anywhere if they had to go to a Toyota, GM, Ford, VW, Honda, etc... gas station. So there should probably also be a standard interface for battery packs like there are for AA, AAA, C, and D batteries. If I drive and need to "refuel" on the road, I should be able to stop at a battery station and swap out the car's battery or batteries in a few minutes to continue my trip. Even if their are 2 or 3 standard sizes and capacities, it will be manageable, but if every model has a different battery it will be impossible to do this.

Getting together and working out a set of standards, which is open or cheap to license, would be a very strong signal to the world that the automotive industry is serious about making the next generation of vehicles work for the future. I hope that the DOE, DOT, ISO and the Press can help with this issue to make sure that it happens.

Thanks,
Michael

Plug-In Prius prototype in Nashville today

Filed under: , ,



The Congressional Tennessee Valley Authority Caucus is a bipartisan group of U.S. Senators and Representatives from the Tennessee Valley Authority area (Alabama, Georgia, Kentucky, Mississippi, North Carolina, Tennessee and Virginia). Today, the Caucus will hold a field hearing on electric drive vehicles in Nashville, and Toyota will be showing off the plug-in Prius prototype there. We're familiar with the Toyota PHEV Prius PR routine (we took one for a drive late last year at EVS23), but we'd be much happier about these events if certain Toyota execs didn't spend so much time downplaying the plug-in hybrid.

In any case, Toyota will also have Camry and Highlander hybrid models on display at the Caucus hearing, as well as a regular Prius. More details after the break.




Press Release:

Toyota To Display Plug-In Prius at Congressional TVA Caucus Field Hearing in Nashville

NASHVILLE, Tenn., June 13 /PRNewswire-FirstCall/ -- Toyota will display a prototype plug-in Prius hybrid at Legislative Plaza on Monday, June 16, during a field hearing on electric drive vehicles called for by the Congressional TVA Caucus.

The prototype Plug-In Hybrid Electric Vehicle (PHEV) enhances the high fuel economy and ultra-low emissions of the popular Toyota Prius production hybrid model with an expanded Nickel-Metal-Hydride battery pack that can be charged by plugging into a standard household electrical outlet. With more electric power in reserve, the vehicle is capable of operating in pure-electric mode for longer periods of time and at speeds up to 60 mph.

By 2010, Toyota will have its next generation plug-in hybrid with Lithium-Ion batteries being tested by commercial fleets in the U.S. and elsewhere. With over 1.5 million hybrid sales worldwide, Toyota is the established leader in hybrid technology.

"As we look ahead, we believe hybrids will continue to raise the bar for new technology," said Robert Wimmer, Toyota's national manager for Technical and Regulatory Affairs, Energy & Environmental Research. "Plug-in hybrids can offer substantial gains in fuel economy and a reduction in total tailpipe emissions."

Toyota will also display current hybrid production models, including Prius, Camry and Highlander. These much in demand models are producing considerable fuel savings and reduced emissions.

"When considering the benefit of new technologies, we must understand the relationship between large sales volumes and fuel savings," Wimmer said. "For example, if we double sales of a hybrid model, the fuel savings is greater than doubling its fuel economy with no change in sales volume. Therefore, it is critical that new technologies, such as plug-ins and fuel cells are introduced at a price point and utility that allow for high volume sales. Otherwise, their environmental benefit will be negligible.

The Congressional TVA Caucus field hearings on electric drive vehicles will begin at 10:15 a.m. in Senate Hearing Room 12. A tour of all manufacturer's vehicles and a media availability will take place at the main entrance of Legislative Plaza on 6th Avenue from 9:30 to 10 a.m.
