Electric VW Experiment – home made motor control

Comments

This was my first attempt at becoming free of the ever rising cost of gas. It worked, but I could never get more than a trip to town and back on a single charge. The motor I used and my crude controller were not efficient enough. I discovered veggie oil and bought a diesel car, so this one is just sitting for now. It was a fun project, and with a 40 horse motor, I could take off REALLY fast!

That's what I would love to do, make a hybrid! what kind of vehicle? From all the people I have talked to (and my own research and experimenting) go with an AC drive motor for your propulsion motor, and a higher voltage to run the inverter. Thats what all the pros do(including GM, Toyota and Honda Hybrids) and the main thing I wish I had done differently

I have a jet starter motor/generator dc but that is what I have to work with so I hope it will do the job,it is a ford ranger but I might try to find a Chevy lov for the weight.
I just got my diesel motor, all happy to start it for the first time, and I had to unceased the fuel pump but I got it going now and it burns about a 1 gal per 8 hours or so but I dont have my generator yet

Poor dude, Sounds like you know what your doing. Hey, try a paper plate, a sheet of foil, and a shiny penny……….. just kidding.

Cool, but next time put all your work into a car that doesnt look like a piece of shit.

IIRC, the VW Superbeetle had a drag coefficient of 0.49. This had to have been very bad for range at speeds over 30 mph. Also, your tires don't look like low rolling resistance at all. Rear wheel skirts, bellypan, removal of unnessessary projections from the body, tapered rear roof spoiler, LRR tires, and other mods could have potentially doubled your range. Due to Peukert's effect, the lower amp draw from this improved efficiency would have increased the AH capacity available for your trip.

During this test, I was purposely going for the worst case scenario. It was only a test vehicle to see what the motor could do. If it would have come anywhere close to doing what I wanted, Then and only then would I have spent the time and money to put the motor into a worthy, streamline vehicle. I did, however, at least over-inflate the tires quite a bit!

what if you took the smallest gas powered generator you could find , what would you need 30,50 amps? 100amps? and run the small gas generator direct drive to the emotor what kind of millage could you get then ? or have the gen charge the batts when you get low on juice? I've always wanted to build an ecar too :) keep up the good work

I know its the point not to be reliant on fossil fuels, but i'm really curious myself. If that's efficient, then a bio-diesel powered small generator would still be a relatively green solution and increase action radius dramatically.

As for increasing the action radius I think you can rest assured he will get absolutely NO action in this car!

That is essentially a prius.

The Prius is not available as a diesel (at least not in the USA)

theoretically, except a prius doesnt do any hybrid work at 'high' speeds.. anywhere above crawl that is

I was told there were no direct connection from the motor to the wheels, that is all electric motor witht he I.C.E. driving the generator.

Put a solar pannle on the roof and let it charge at work!

Cool, did you talk with ISITEL and their EMV Electro Magnetic Vehicle?

Hats off for trying all the electro yourself!!! I'd love to do that one day!

Not as far as i got it. I'm not too impressed by the Prius, they appear to be doing a good-news show more than actually improving anything. A 1.3 litre efficient engine is the real reason for the efficiency increase and the electric engine just compensates for the terrible lack in engine force from stop IMHO

I gave you all my respect for trying man. How my horse power you think i would need to make a motor run a car efficiently ?
