Progress On Electric Cars 594

Mike sends along a couple of items of interest to those anxiously awaiting the era of production electric vehicles. First, there's the upcoming Aero EV, which Shelby Supercars claims will charge in just 10 minutes and will be able to produce over 1,000 horsepower, powering the vehicle from 0-60 mph in less than 2.5 seconds. Then there's the announcement by Aptera of the first pre-production model of the Aptera 2e, which will have a top speed of 90 mph and go around 100 miles on a charge. This EV also features a strong and aerodynamic body, a lithium-based battery, front-wheel drive, and an improved door design. Release is planned by October of 2009.

    What, no love for the Big 3? Lemme see here. We've got the range-extended Town & Country EV [chryslerllc.com] from Chrysler that will do 40 miles on a single charge, plus another 360 miles using a mixed gasoline-electric propulsion. They're also working on Dodge and Jeep [autoblog.com] vehicles with similar designs.

    Ford used to have the market in a bag with their Ford Ranger EV [wikipedia.org] pickup. Of course, they discontinued it in 2002. Now they're playing catch-up with the rest of the market. They are promising an electric vehicle by 2011 [wired.com], so there should be plenty of competition in late 2010/early 2011.

    Speaking of competition, what discussion is complete without mentioning the Chevy Volt [chevrolet.com]? Still the gold standard for the emerging industry, it will be anyone's guess if it lives up to the hype.

    Then there's the announcement by Aptera of the first pre-production model of the Aptera 2e

    I rather like the look of this car, but I am concerned by a couple of issues. First up is the single back wheel. Won't that make the vehicle a rollover hazard? I presume the front wheels are extended to help mitigate this issue, but one good blowout looks like it could send that sucker fishtailing right into roll. (And for that matter, how servicable is that tire?)

    My second issue is the power-train. Generally you want as much weight sprung as possible, and electric motors are heavy. Aptera seems to understand that as it appears there is an axel linkage on the front wheels. Presumably this is how power is transmitted. Is having that axel exposed going to cause any safety and reliability issues? I'm just imagining something flying off the road and getting wrapped around the the axel. Or in an accident, a pedestrian getting an appendage caught in there.

    Or is this a rear-wheel drive vehicle? In which case, is that axel really necessary? Could'nt the steering be accomplished by swiveling independent pods rather than linking them?

    Just my 0.005 cents worth after accounting for inflation. :-P

    P.S. The Shelby looks pretty darn sweet! I'd never spend money to purchase a vehicle like that*, but I wouldn't mind taking her for a spin.

    * Unless I had way too much!

    Let's hope that SS's claims are true. This would eliminate the need for hydrogen cars as well (water vapor is another major greenhouse gas).

    God forbid water vapor should be in the air!

    The Tesla and Aero are interesting, but waaaaaaaaay out of normal price range. And most of the other electric cars don't cut it. This is what I want, and probably what most consumers want:

    1) A real sized car, not a tiny econobox with motorcycle-sized tires
    2) Range of at least 100+ miles per charge (I am guessing 80% of people are within a 20 mile round trip to work, 90% within 30 miles, and 95% within 40 miles; so other than occasional, long road trips, that is a lot of coverage).
    3) Ability to charge with regular home voltage/current (don't care if it takes several hours to charge overnight)
    4) Real performance- at least as fast (accel & top speed) as a gas car (like a 3 liter V6, not a 2 liter 4cyl)
    5) Features- full A/C, heat, heated seats, auto climate control, GPS, cruise, auto lights, auto windows, defroster, etc
    6) Safety- comparable to a quality conventional car- crumple zones, airbags, seatbelt tensioners
    7) Reasonable price- comparable to a quality conventional car, although many of us are willing to spend more for the advantage of electric... but not 50%+ more

    When that happens, I am betting people will flock to them. Hybrids (plugin or not) are just too complicated; they have all the complexity of a gas engine (cooling, emissions control, transmission, lube, injection, etc) with all the added cost of electric (motors, batteries, charging systems).

    A plug-in version of the new Honda Insight Hybrid comes close to those specs, but I suspect for a pure electric the 500km range is incompatible with the other requirements -- the batteries alone would cost over $20k for a 500km (300mi) range. I would settle for a hybrid with those specs.

    I do not understand why these cutting edge car designers can't make a conventional looking car (something as boring looking like a Corolla). Your friendly neighborhood soccer mom or PTA dad is not going to want get caught driving this.

    I am not saying they should copy Corolla's body style but for heaven's sake, make something that looks like its meant for this planet. I am betting that these people probably spent a good deal of money on the shape designer. This car will appeal to teenage nerds, extreme yuppies and the Hollywood set. How many of them are there anyways ??

    If they are really serious about addressing the actual gas problem, they should make something that looks a little more common (oh horrors !). This car looks like a rich man's gimmick. Don't be surprised if the middle class gives it a miss.

    Humans aren't natural?

    I presume a "yes." Things humans make aren't natural? What if a monkey learned to make something, would it be natural?

    Obviously I have a point to make here. From the evolutionary standpoint that most say they hold, human machinery is just as natural as a monkey using a bone as a club (sorry, I just watched 2001: A Space Odyssey). It's time to define "nature" and why I don't get to be considered "natural." Which seems like it will be hard to do form the scientific/atheistic viewpoint. Even more so when people want to tell me that genetically modified stuff is just as natural as non GMO stuff... "natural" stuff. So on one hand, we can modify nature and be natural, and on the other hand we can't.

    And yes, this is on topic, since "greenhouse gas emissions" implies that there are natural and unnatural things, and most of the time, "global warming" is linked to those horribly unnatural and wicked humans.

    As opposed to whatever caused the last ice age when humans weren't around, I guess.

    If you live in an apartment or in the city and have to park on the street, you really don't have a good way to plug a car in over night. I think I will patent a 'Charger Post'; insert credit card, open door and plug in car, lock door, next day insert card again to open door.

    It's a fact overlooked by many.

    They should keep overlooking it. H20 is a greenhouse gas, but it's close to saturated nearly everywhere on the planet already. If you put a little more in, it'll just rain out. In the places where it's not saturated (which is pretty much only near the poles), it'll freeze out.

    I hear this argument far too often, and it makes no sense.

    Let's think about it this way... How much easier would it be to replace every single vehicle and retrofit every single service station in the country if we decided to switch between different chemical fuels? Compare that to the difficulty of updating where we derive electricity...

    SURE, it's COAL today... but will it always be coal? If we try to nay-say electric vehicles and talk our way into biofuels or hydrogen, and we run into issues obtaining it in the future, we're stuck. Electricity is the universal medium -- it's the same network to distribute, store, and utilize at the consumption end regardless of how we make it... that means the cost of retrofitting is significantly lower at the power generation side when/if we decide to switch down the road.

    Electric motors are exceedingly light for how much power they produce. Batteries are heavy.

    Also I think we will soon see integrated motor/wheel/brake assemblies on the market, so the mass overhead is shared between three functions.

    There is one thing that doesn't seem to be discussed about the Top Gear bit. I agree that emphasizing what happens when you run out of charge--when they didn't kill the battery--isn't entirely fair, but there is a difference between running out of charge and running out of gas.

    I can easily walk to a gas station and carry a couple of gallons of gas back to the car, which is enough fuel to carry me at least a couple dozen miles in even a heavy SUV.

    How many miles worth of charge can you carry back?

    You miss the point though.

    If you really really need something that matches a gasoline car for a particular purpose like a ski trip to Tahoe, hire a car for the weekend.

    For Mr and Mrs Smith going shopping or commuting, a short range electric car is sufficient.

    Ideally there would be an associated enlargement of public transport, light rail and intercity rail to take away those medium range journeys.

    It's a whole integrated solution not one thing to solve all problems.

    There's no reason to think that things have fundamentally changed.

    Actually, there is an amazing good reason to believe things have changed. All the previous spikes in gas prices have been caused by supply shocks. This means that various oil producing conglomerates have decided they would or could not provide the amount of oil because they didn't like the cost of it. This past years price shock was caused by a demand spike that could not be met. With the rapidly growing economies of China and India (~1/3 of the world's population) there are going to be more and more demand shocks on resources that have never been seen before. I'm not upset at China or anything but the game has changed with their growth and that means that there need to be real changes in how we view our resources.

    I would suggest keeping the battery pack warm using the same power source that is being used to charge the battery. Also, insulate the battery pack, since the batteries typically warm themselves as a result of being discharged, due to their own internal resistance.

    This mainly becomes an issue if you park the car somewhere for a long time in a place that is cold, but there is no way to plug the car in. I suspect that parking garages would start offering electrical outlets for charging the parked vehicles. Smart grids [google.com] would probably help with this, causing the car owner to be billed for the electricity used to charge and pre-warm the car (or credited, if the car contributed excess electricity to the grid during daytime peak hours in periods of relatively mild weather).

    Similarly, the car interior could be pre-warmed (or pre-cooled in the summer) when plugged in.

    Nuclear power is an excellent idea.

    I prefer fusion myself. Big 'ol billions of years of reliable fusion power plant... and our planet orbits it constantly.

    Now we just need enough collectors, via solar panels and concentrating solar power plants, to use all that freely available power.

    My old Nissan had less power, it had a KA24e engine in it, 134hp peak and 154ftlb peak. The amount of power isn't what's related to handling; it's that when the rear wheels slip, I can adjust steering to correct fishtails. Try that when the front left wheel slips 20%, the front right wheel slips 5%, and the car accelerates -- to the left, while you've got the wheel a quarter turn right. Any attempt to steer when you either hit the gas a bit too hard or just glide over some extra-wet slippery slush with one wheel is moot, the car is going where it wants to.

    Electricity can be made from CSP Thermal Solar and Wind
    and if those run out the whole planet is dead anyways.

    Coal is set to run out a lot sooner due to the rest of the world
    ramping up use of it massively.

    The coal producers in the US have nothing to fear of the US
    getting off coal, China is building coal fired plants faster
    than any 2 other countries on earth combined.
