Note to Silicon Valley automotive start-ups: include a “shut the Hell up for the rest of your life” clause in your employment contracts and hire a couple of razor-toothed lawyers to enforce it. To wit: diss-missed Tesla Motors’ founder Martin Eberhard has been blabbing on his “Founder’s Blog” recently, and you couldn’t ask for a worse “champion” for the company’s 100 grand-plus Roadster. “Soon after I got my car, I noticed a funny thing: the ESS coolant pump seems to run all the time. Even when the car is off. Even if it has been off for a long time. Even when the car is plenty cool. You can hear it run, and many people have commented about the noise of the pump and the noise of coolant gurgling into the overflow reservoir. The Tesla people tell me that when the battery is half-way discharged, and the car is off, and the ESS is cool, then the pump will shut off. Fine. But my average daily drive is less than 60 miles, and I have only driven far enough to drain half the battery 4 times since I got my car three months ago. So, except a few hours on these four occasions, this poor pump has been running 24 hours per day, 7 days a week for three months solid… Here is the kicker: 22 percent of the energy consumed by my car happens while my car is parked! Twenty two percent. Imagine that.” Easy enough. And I get the implications for battery and pump life. We’ve long maintained that Tesla is long on hype, short on engineering. What I don’t understand is why anyone would put Gulf racing colors on an EV. Post-modern irony?

You would think a bunch of guys in Silicon Valley would understand the nature of “0” and “1”. Just in case they don’t, here’s a hint: When you park the car and turn it “off”, that state is “0”.
I hope that helps. Mr. Musk, you can just deposit my payment for this consulting time in my PayPal account. Thanks!

Because Gulf livery freaking rules. Even if the loudest sound coming out of your car is “the noise of the pump and the noise of coolant gurgling into the overflow reservoir.”
The problem is that you can do a lot of useful things while off that may make some engineering problems easier.
For instance, some of the worst thermal loads in modern cars occur AFTER the engine is off because you loose a lot of the active and passive cooling. Add in that some materials don’t like being hot (the natural rubber in the engine mounts being one) and you’ve got some serious challenges making things reliable under such conditions.
Running cooling pumps when off may be extending the lifespan of motor, controllers, etc. However, they seemed to have made the logic that shuts the pump off a bit too conservative in keeping things cool.
Maybe a shutoff after 20 minutes, no matter what?
You’d think a founder of a company might know enough about his car to isolate why the pump is still running and which wire to pull until he gets it fixed – assuming that it wasn’t doing something useful.
Man I want an EV so bad. Just want an ordinary car with a proper EV driveline and battery.
Wondering how fast $2.95 gas is going to kill the average consumer’s enthusiasm for EVs? And will gas spike again near $4 next year?
rm,
I think you’re right on target. Laptop batteries are especially sensitive to heat, and the Tesla has 700 pounds of them.
Why is it that the green loving editors at TTAC absolutely HATE the Tesla car??? Does it have anything to do with the fact that it actually has some style and perhaps even some performance???
Wolven:
Nope. Guess again.
Edward Niedermeyer: Ditto
Farago:
Hmmm…. How ’bout;
Cuz it costs $100,000?
or
Cuz its not made by Toyota?
or
Cuz the company was started by silicon valley boys?
or
Cuz Jay Leno bought one?
or
???
I give, please tell me.
Wolven,
Comments like that (from what I’ve seen) seem to go under the “flaming” category around here. Perhaps they’re pessimists, or simply don’t like the Tesla? Who knows? It’s their website, so they’ll pontificate how they please.
Wolven :
Well, first I don’t hate the car. It’s a car. I hate the hype perpetuated by the people who produce it.
But there is a way out…
If I adopt a Jewish boy and raise him a Muslim. Just kidding. All Tesla has to do is provide us a single car for 24 hour evaluation by an independent expert.
And then we’ll talk.
Campisi:
“Flaming”, in case you hadn’t noticed, is what Farago does for a living. (Just ask the auto makers) And I, (just one of many) happen to really appreciate what he does and the skill and art with which he does it… and he knows that.
Furthermore, Farago is a big boy. Big enough to take my less than politically correct comments. He’s also perfectly capable of removing and blocking my posts if I get too far out of line.
In spite of my question, I actually agree with Farago 80% of the time. But his dislike of the only auto company actually making an electric vehicle while at the same time supporting the enviromentalista’s on most every other issue I find confusing.

I’m very much aware of that; hell, technically I’m one of his employees.

I couldn’t care less about whether or not you upset Farago. :p I’m just trying to help you out before you inadvertently step over a ledge you weren’t quite expecting.

There are plenty of other companies that build electric cars. In fact, reviews for two such cars are in the hopper. He’s just sticking to the guns he loaded back when the Tesla Roadster was just vapourware.
I hate the hype perpetuated by the people who produce it.
eeaaauuuhhh… well… maybe. But, just to be fair, how else are you going to get people to give you a few (O.K., more than a few) million dollars to actually build something. Plus remember, these are silicon valley brats where “hype” is what sells everything. While I have serious doubts as to the validity of hooking a billion pacemaker batteries together to produce an automotive heartbeat, hey, I gotta admit, they at least got it to work long enough to film a few promo videos and sell one to Leno.
More importantly, they gave it some style and are aiming at real performance as well. So in my opinion, they are going in the right direction. Unlike the used prophilactic styling and performance of the Pri(ck)us and the (re)Volt.
What do you mean by an “independent expert”?
Wolven —
Tesla has, from day 1, made grandiose claims about range, recharge time, and performance. None of these claims have been sufficiently tested by an independent 3rd party, and the limited media exposure that test cars have received has indicated that these grandiose claims have no basis in reality. Furthermore, their claims don’t jive well with physics, or with the performance numbers for existing EVs.
And on top of that, this is a brand new company with 0 experience building cars prior to this one, hell, with 0 experience engineering anything, and there’s no real reason to trust their claims. So it’s frustrating for the media and fanboys to tout this car’s numbers over and over and over again, when all indications are that they’re make believe.
I think the editors of TTAC would agree with me when I say that I’d love to see this car meet all the expectations Tesla have built up for it and change the world. But at the same time, I just wish they’d come out and say that the 220 mile range is bogus, that it’s more like 75 miles when you’re driving it with spirit, etc.
