Pondering The Possibilities of Swappable Electric Vehicle Batteries


Readers of Conservation Value Notes know that I'm an enthusiast of Better Place electric vehicle battery systems. Running low on charge?  Instead of having to plug in my electric vehicle (EV) for hours to recharge, I can simply pull into a battery swap station. In minutes, I'm driving out with a fully-charged battery!

I can envision how battery swapping capability might offer ways around the range limitation of electric vehicles, a key factor holding back peoples' trust in them as everyday cars.  Let's say I need to drive to Tahoe for a ski weekend in my Better Place-powered EV.  If my limited-range spare battery (which I keep in the trunk) is not enough to get me there, I simply rent an extra battery or two (and maybe a portable overnight charger), and I'm good to go!  There's another a business opportunity (and an entire service sector) that could come out of the EV industry -- in the emerging paradigm detailed in Lisa Ganskey's The Mesh.

Even better?  How about if my house is powered by a solar electric system and Better Place offers a home back-up power supply in which the batteries are compatible with my EV?  They can therefore double as extra batteries for road trips!  Heading out of town for a camping trip in a wilderness up near Mt. Shasta? I simply pull one or two of the batteries out of my Better Place-compatible home back-up power supply and toss them in the trunk.

Granted, I have no idea how near or far Better Place actually might be from this vision.  I'm just pondering the possibilities of swappable EV battery technology.

What do you think -- which battery system is going to win in the emerging world of electric vehicles?

Keeping Current on Electric Cars

Here's the latest on what car companies are doing to get an electric car into my driveway and yours.

Again, sounds like U.S. automakers are lagging, to the point of embarrassment.  Says car rider and writer Jim Motavalli:

I would say probably the smartest overall strategy for vehicle electrification is coming from Nissan, a Japanese company, and what's smart about their approach is they've also got into the charging business. The Renoit-Nissan alliance has built strategic alliances around the world to set up charging stations.

Something I hadn't thought of is the drive to leverage car charging as an opportunity to get consumers to shop:

We still have a massive learning curve in the American people to get them used to the idea of driving an electric car and charging up. I do see a very fast spread in which charging technology will take off and big-box stores, for instance, will have free electric car charging, and this will get people to visit them. When you think about it, a charge doesn't cost very much, it might cost three or four dollars, but if you get somebody in the store and they basically have to stay there until the car is charged - a fast charge might take 20 minutes - you've got a captive shopper for 20 minutes. That is worth more than four dollars. That's why you get this move towards not only widely available charging, but free charging as a competitive advantage.

Now that's a fresh angle on the economic benefits of our clean energy and transport transformation, to be sure!

The Path to Lower Oil Demand and Gas Prices: A Green Vehicle Revolution Is a Much Better Route Than a Global Financial Crisis

Would a dramatic reduction in demand for oil caused by a green vehicle revolution cause the same type of reduction in oil prices that the global financial crisis has?

Overall, I don't see why not.

In fact, I'm guessing that the eye-opening impact of the financial crisis on oil demand and prices is exactly what major oil producers are afraid of should the world experience a green vehicle revolution.

Think about all the benefits that our society would receive from an oil demand-destroying green vehicle revolution that lowers gas prices via efficient, clean technologies rather than via a global financial crisis:

  • Broad economic stimulus beyond the oil sector: the combination of highly efficient clean vehicles and low gas prices will free up untold fortunes of peoples' gasoline money to be spent on all things non-energy, providing a green injection of economic stimulus far and wide. Previously, I noted that:
    Switching from a car that gets 20 mpg to one that gets 50 mpg will save the average American nearly $1,100/year in gas costs at $3/gallon (given the average distance Americans drive per year – about 12,000 miles; savings rise considerably as gas prices and miles driven go up). That savings is nearly two times the cash provided to us by our 2008 stimulus checks! Multiply that by the 112 million households in the U.S. alone, and that’s $123.2 billion/year that American households are now spending on gas that with a mandate for more efficient vehicles, they would have to spend on…everything else.
    Even at currently lower gas prices, a Clean Vehicle Revolution promises to be a significant stimulative force in our economy.

  • Greater economic stability as we break society free from the whims of increasingly unstable oil markets: I don't know anybody who wouldn't be thrilled to see more stability and predictability in their energy bills. The volatility of gas and other energy prices crimps many a budget -- from families to businesses to whole governments. Another -- and major -- economic benefit is that the U.S. will no longer need to spend untold $billions on military operations to secure oil supplies in the world's most unstable regions -- which cost us dearly both economically and politically. A Clean Vehicle Revolution promises to be a welcome stabilizing force.
  • Massive environmental benefits - climate change and beyond. Not only will global heating carbon emissions be dramatically slashed, but so will emissions of other pollutants that have negative -- and expensive -- impacts on human well-being, like particulates, ground-level ozone, and acid rain-causing pollution. As we've noted previously, these environmental impacts of vehicle pollution inflict untold $billions in health-related, agricultural, and quality of life damages upon families and businesses each year. A Clean Vehicle Revolution will be healthy for our environment, and as a result, for our families and businesses.
  • Significant security benefits will result from cutting off the flow of dollars from our gas and energy purchases that currently end up funding harmful agendas of countries that don't like us. Reports are that the Saudis, Iranians, and Russians -- countries that either showed increasing military boldness as oil prices rose (e.g., Russia and Iran), or are breeding and financing terrorism (e.g., Iran and Saudi Arabia) -- are struggling with their first budget deficits in years. That means less money to spend on military adventurism and support for terrorist groups. Of course, the root causes of terrorism, such as poverty and the associated lack of education and social services, will still need to be addressed.
  • Obviously, there are many more environmental, economic, security, and quality of life benefits that we will realize via a green vehicle revolution. You get the picture. Please feel free to contribute more in the comments below!
A Temporary Window of Opportunity - We Need to Act Now and Act BIG

Unfortunately, unless we act now to implement a green vehicle revolution at World War II mobilization-level speed, the low gas prices that we're currently enjoying will be painfully short lived. In fact, as soon as the economy starts to recover, demand for oil will recover with it, and growth will hit what I call "The Petroleum Ceiling". This is especially likely now because low oil prices are slowing the development of new production projects. Thus, once the recovery begins, oil supplies won't be able to keep up with rising demand, and there is a real danger that we will experience a far worse price spike than this past summer's. Should this happen, it could potentially plunge us into a much more dire economic crisis than the one we're currently experiencing -- one rooted in Peak Oil.

The good news: we've learned this year just how quickly demand destruction can lower oil and gas prices. Now, let's make this demand destruction permanent by implementing a historic green vehicle revolution that stands to become the type of victory story that our history texts tell for generations.

America can lead the way by devising a smart Auto Industry Bailout that propels Detroit into the forefront of a new age of efficient, green vehicles. The result will be both a psychological boost that helps lift America out of our recessionary malaise, and a broad economic boost as the proliferation of next-generation vehicles cuts our energy costs and inspires the creation of whole new sectors of supporting industries.

Why Do Americans Prefer Our Gas Money Going to Foreign Oil Producing Countries Over Taxes That Put It To Work Benefiting America?

One morning last week, I woke up to one of the more thought-provoking radio commentaries I'd heard in some time, from CBS Radio's Dave Ross.

He noted that gasoline prices have gone up more than 70 cents per gallon in the last year, and that while the public is clearly in pain, the outcry is not nearly what it would be if a tax had caused the same price increase.

Why is it, Ross asked, that Americans have little problem with our untold gazillions in gasoline money going to Saudi Princes (and other such Middle Eastern leaders who oppress women and, yes, Palestinians, among others and don't allow Jews into their country), but collectively freak out over the prospects of a carbon tax that would put our gas money to work improving America - helping to fund renewable energy development and advance energy independence, strengthen our education system, repair our crumbling bridges and infrastructure, and so on?

It was one of the best points regarding the sociopolitical barriers to solving Climate Change and Peak Oil that I'd heard in a long time. What's the answer? I'd love to hear some of your thoughts!
