This is amazing! Beating up ona Vette, a BMW and everything else. [img]../images/emoticons/surprise.gif[/img]

Cool project [img]../images/emoticons/thumbsup.gif[/img], but it just ain't the same w/o the noise [img]../images/emoticons/wink.gif[/img].

60 batteries would by a nice 383 GM stroker, dressed and blueprinted, from Summit Racing. Reminds me of the slot cars I raced as a kid. If the electric class catches on they can install a "power rail" at the strip. [img]../images/emoticons/laugh.gif[/img]

Where does the electricty come from to charge the car? Coal plant?

Yep, electric motors develope their torque almost instantly. Look at the torque of a relatively small starter motor in a 350 chevy truck. As soon as someone comes up with a good electrical storage system (one that would allow 300-400 mile range and be recharged in about the same time it takes to fill a tank with gas) or a portable electrical generator (fuel cell) then we are in business. We have plenty of electric motor technology. Flux capacitor

Why do they need to have a charge for 300-400 miles when you could have a small generator say 2500 watts powering a charger to the bank That would be about an 5hp engine and would burn about .7gph gas and less for diesel

Or some way to capture the kinetic(sp?) energy coming from the moving parts, car should be able to charge itself.

First, I think it's a pretty neat project that shows EV potential. That being said, there are a lot of hurdles to cross before anything like this comes to the street as a common vehicle.

The biggest problem is probably range. A battery system that contains enough power for long distance is not readily available. Although most drivers actually use their vehicles well within the limits of today's battery technology, most perceive 20-40 miles as too limiting. Cost of advanced battery technology is prohibitive currently. Life span of the batteries and disposal/recycling are also issues that need answers.

Electricity from power plants is far more "clean" than the power produced by internal combustion engines. Overall, if cars were run on grid produced electricity rather than gasoline, there would be less pollution.

Small generators do not produce more energy than they consume so attaching that to a vehicle as a means of regenerating power for the batteries while the batteries are being depleted thru driving would add some range but at some point the batteries would be discharged below safe levels, further shortening battery life. I read somewhere that it takes about 20 horsepower to maintain highway speeds in a small car so a 5 hp generator would be losing ground on long distance trips. Emissions would still be a factor with small generators.

There is regenerative braking used in hybrid cars today although I haven't read how much it puts back into the system. I can't imagine it's a bunch. One of the biggest problems is acceptance rate, the ability of the battery to take a charge. Obviously, during braking there is a large energy event in a very short timeframe. How much of this energy could the battery capture and how much would be wasted?

I've been following hybrid technology for boats for a while, much of which spills over into pure electric and hybrid car technology (or vice versa). These are just a few things I've learned. My pontificating is over for the day.

A 5hp generator can produce 120 or 240 volts which can power a fast charger This can maintain a battery a peak levels meaning that the amount of discharge would be equal to the charging elements Once Peak demand was over say at a stoplight or or slowing down an exit or whatever The charger can gain to replenish the charge to full capacity This could easily be on demand In the same way that an engine kicks in on the current class of hybrids

As I wrote, a small generator would lose ground on the highway. City driving might give the generator time to catch up, but then again, city driving probably wouldn't deplete the battery of an EV to a level that required a recharge during a days use for the average driver.

I'm certainly not an expert on this subject but I have read enough from experts that say a small generator won't work. The hybrids have a large generating capacity, so much so that some consider them gas powered cars with an alternate drive engine. That is to say, hybrids are being sold as electric cars with a gas engine for additional power whereas the opposite can be argued - that they are gas powered with an electric boost.

They don't get better mileage than some other cars available. They just put the power to the ground with a different method.

Cool when guys dream up stuff in the backyard.

Torque is torque, and electric motors are 100% efficient about delivering torque.

I think the main thing here is he has 1200lbs of batteries resting on a tubbed out Datsun 1200, laying right over the rear axle, delivering all that torque straight to the rear axle.

Drag racing is about physics, nothing less. It would be a different story if he was not allowed to charge at the racetrack.

Drag racing is also about noise, smoke, and adrenaline. Same as boating. I'd hate to see it go down the enviro-friendly track.

Hydro electric?
