Slashdot Mirror
A Honda Civic With no Gas Tank (Video)
It took Dr. Adam Blankespoor two years and $14,000 to convert his 1996 Honda Civic into an all-electric plug-in vehicle. He's an automotive engineer and researcher, but if he can do it, you can probably follow in his footsteps and create your own electric vehicle if you are so inclined. He talks about a 45 mile range, with 30 miles as a practical limit. That's not competitive with the Tesla S, but there's also a massive price difference to consider. This is another person Slashdot met at the Ann Arbor Maker Faire. If you want to see what kinds of electric vehicles other have made, possibly for inspiration, the Electric Vehicle Photo Album is a good place to start. And if you want information on how to build your own electric car, using "electric car conversion" as your Google search term will put you on the track of more electric car information than you can shake a Tesla Coil at.
SHOCKING!
$14000 buys an awful lot of gas.
if you don't stop drivin' that hot rod Lincoln
“He’s not deformed, he’s just drunk!”
It is geeky and cool. If you don't get that you might be on the wrong website.
Geeky and cool does not mean useful. In fact most of the best geeky and cool things are not useful at all.
If I were God, wouldn't I protect my churches from acts of me?
Same reason nerds here would hot-rod their PCs or other electronics: the hobbyist does it for passion, not practicality! What these people learn - at their own expense - can inspire and/or educate others.
Oh boy, here we go.
Crumple zones and chassis structure are not touched. In a low-speed collision, nothing more happens. In a high-speed collision, there may be some leaking of electrolyte (The same way the lead-acid battery in your ICE car can leak), but there will be no dangerous inflammable liquids spilling around. Electrically, the battery pack is automatically isolated via inertia switch and circuit breakers and isolating fuses, along with contactors which separate on 12v power loss.
No. In an accident, the system is automatically isolated, as noted above. In addition, the power-carrying cables from front to back run along the underside of the vehicle, usually along the old exhaust tunnel, keeping them far away from anywhere emergency services may be operating.
Oil gets spilled. Some metalwork gets crumpled.
Some metalwork gets crumpled.

Hey, just incidentally the New York Times reviewed the Tesla Model S today. There seems to be a lot of electric vehicle haterz on Slashdot lately, I don't get why, but if you're legitimately interested in the tech, rather than just Detroit astroturf, the NYTimes review is certainly worth a read.
"Put simply, the automobile has not undergone a fundamental change in design or use since Henry Ford rolled out the Model T more than a century ago. At least that’s what I thought until I spent a week with the Tesla Model S."
Dealing with stall currents is tough on EV design.
most people don't know what stall currents are. several wikifascists took issue with improvements to the "wheel hub motor" wikipedia page, recently, when facts were presented that showed that the efficiency of EV motors is far, far worse at low RPMs than any ICE vehicle ever could be.
for those people not familiar with "stall currents", stall conditions for an electric motor is when it is operating at or just above 0 RPM (i.e. stall). not only is the motor not moving (so there's not enough air circulation), but the electric wire, as an inductor, is capable of absorbing far more current. that just means more heat is produced, and that the efficiency is lower. a typical EV motor can be only 12 to 15% efficient (!!) at its lower RPMs! avoiding this worst-case situation is flat-out impossible with a Direct-Drive (Wheel Hub) motor. for a bicycle that doesn't matter so much (you can always pedal), but for a car it's a serious problem.
this is why VW's XL1 concept car has a *seven* speed automatic gearbox. electric motors have to be kept in their optimal efficiency band, just like an ICE does. it's complicated! much more complicated.
The Smart Four Two is safer in a crash than any SUV ever made, but a lot of people dont have the IQ to realize that.
I suggest you go to youtube and watch some of the Smart crash test videos. Against larger cars, the Smart usually gets punted quite far.
If everyone drove something that size, sure. But mass does matter.
