The Best, and Worst, Places To Drive Your Electric Car 212

sciencehabit writes For those tired of winter, you're not alone. Electric cars hate the cold, too. Researchers have conducted the first investigation into how electric vehicles fare in different U.S. climates. The verdict (abstract): Electric car buyers in the chilly Midwest and sizzling Southwest get less bang for their buck, where poor energy efficiency and coal power plants unite to turn electric vehicles into bigger polluters.

    Well, at least the pollution they caused wasn't being ejected into city centers where people would immediately breathe it in, but instead at a centralized location where big bucks could be spent to achieve big gains of pollution reduction.

    The main benefit of electric vehicles is the ability to move to an electricity-based society, at which point the problem that would remain is getting clean electricity. Filling a desert with solar power plants would probably do it.

    • where big bucks could be spent to achieve big gains of pollution reduction.

      Indeed, they certainly could... :p

  • Such as performance, see Tesla's insane button [youtube.com] or this review of the Zero motorcycle [gizmag.com]
  • If (local/state/nation) governments were focusing, all vehicles that had a low co2/distance rating per region would get subsidy. This would make diesels the best bet because they are by far the cheapest co2 reduction per dollar spent. People/governments have a limited amount of money, we should do the most good with it.

    go ahead flamod me as I crashed in flames on the last ev article, but yes if you live in a few select areas (80% of the world dosent) or have a custom solar installation then yes electric

    • You don't need to upgrade plants or build more.
      First of all 60% of your power plants are ideling at 5% load or less at night, or are completely offline.
      Secondly even if all your cars over night would turn into EVs, the amount of power they need is abysmall.
      The Tesla has a 85kWh battery, loading that in 2h draws 22kW. A million cars will draw 22GW (if they all load at the same time). With smart grids you can easy manage the loading, you use the cars as balancing power. If a great amount of power users (or bi

    I know that my current gas vehicle (2010 Elantra) gets about 360 miles per tank in summer, and goes down to 280 miles per tank in winter, due to (Canadian) road conditions and temperature.

    If an electric only gets 15% worse, as the article seems to imply, this is still an improvement over my increased gas consumption in winter...

      Don't forget the fun that is "winter gasoline". The change in formula to bring about easier winter starting and combustion scrapes some number of MPG off the chart (10%? I'll admit I don't know, but that seems right.)

  • i heard of someone who bought a prius: they live in scotland (south west, near ayr). they noticed a huge drop in fuel economy (down to 30mpg) so recorded it, and year after year they found a clear correlation between winter and the drop in fuel economy. the extra cost of the vehicle, the insane pricing for replacement batteries (over $1200 per battery and there are 30 of them), and, finally, the fact that they were not actually getting better fuel economy than an equivalent ICE car, they sold it... and us

  • It's all to often claimed that EVs just shift the pollution to the power plant, however even to the very limited extent that is true (EVs are much more efficient than ICE cars, and so are the power plants) that fails to account for the energy cost of producing the gas in the first place, which is comparable to what EVs consume on a per-mile basis: before an ICE has even burned the fuel, it's already used as much energy as the EV will just by filling the tank.

  • The study seems focused on Leaf, but the Tesla has an active cooling system that the Leaf lacks. Some Leafs in hot climates had a lot of battery degradation. That doesn't seem to be happening with the Teslas, nor should it.

    Li-ion cells do degrade with both time and charge-and-discharge cycles. Data coming in from Teslas seems to indicate time is much less a factor, and charge cycles are the main determinant. The implication is that a bigger battery pack will last longer, since it takes more driving mile

      Also depends on how you charge it. The fast chargers will kill a battery faster. The chemicals in the goop do migrate, and though they start out evenly distributed, the uniformity of the chemical density degrades over time. Fast charging on a regular basis accelerates the degradation.

  • Here's a general list of where NOT to drive your electric car:

    Almost anywhere more than 50 miles away from your garage.
  • Whenever an electric car starts making the rounds, immediately all the ranges are "up to" whatever. In fact, on discussion forums, some electric zealots will usually march in and talk about how I don't *need* a range of X (where X is 80 miles, my round trip to and from work).

    The other big piece is that it's not exactly obvious how the range shrinks with age. Personally, I have zero interest in an electric car until it can do 80 miles on a charge under ALL circumstances- snow, cold, 10 years old. Anything

  • The report missed how EVs keep the money local to the nation, while gas/diesel cars help fund terrorists around the world.
