There is an electric Rabbit in Eugene, Oregon with a bio-diesel fueled pusher for long trips. I have seen it at the Solar fair in John Day, Oregon, about 150+ miles away. FYI.

I bet you get a few comments about staying out of the water, though! bzzt.


I have thought a generator trailer (originally i was going to put a genset in the tray of the ute i was going to convert) would be a great idea for the occasional long-distance trip you might have to take. I'd rather rent one of those, than a whole new car.

And for my motorcycle conversion (getting there, so close to starting!) i think a combination luggage/generator trailer would be great for road trips.

Haha, never thought of that. Very true!

Or a cool looking side car. But there goes your aero... trailer is likely more efficient (for a given load).

Just checked the odometer: the car has gone 4814 km (2972 mi.) since the conversion.

Assuming I could have gotten 60 mpg US (3.92 L/100 km) in the same driving conditions, that's 189 litres (50 gal) of gasoline not burned. 5 tanks worth.

Received this question via email:

Quote:
I have watched all your videos and I gotta say, I'm impressed with what you have put together.


Can this be done with an Automatic? You know the saying "Can't teach an old dog new tricks" lol I could never get the hang of shifting a standard and would love to build an EV.


I always see affordable Swifts out there.


ThanX
Answer is: yes, it can be done with an automatic. It's less efficient though (losses in the torque converter, plus some automatics require the electric motor to "idle" even when coasting/stopped, to keep up pressure in the automatic's transmission fluid pump).

From what I've read you should expect about 10% less range with an automatic transmission conversion.

That said: you can design an EV conversion with a manual transmission that is effectively an automatic (meaning, no need to shift, or very infrequent shifting). Much of the time, I just leave the ForkenSwift in 3rd gear, and do all my in-town (level grade) driving without any need to shift.

All the commercial/production EV's I can think of have direct drive, single speed gearboxes (not torque converter based automatics). You can get away with this if you have enough power from your batteries / controller across the range of speeds you expect to drive.

Personally, if building an auto tranny EV, I'd install a high performance torque converter with a stronger lockup clutch, and just keep it locked in most or all situations. Then, the efficiency difference is much smaller.

Good gravy! At the rate I'm going, it would take me 10 years to rack up that kind of mileage! I wonder if the batteries will hold out.....
