Default Electric pusher trailer

Greetings:

I'm think of doing a pusher trailer for my first project. I have a 1967 Ford truck that weighs around 4000lbs that it would push. I have $4000 to do the project and I already have the trailer. So, I would need all the electrical stuff plus a drive axle (thinking of a 9in ford). I'm looking to get 25-30 miles pure electrical range out of this. I'm thinking of a 96v system (would that be enough?)

I don't want to convert the truck right now as it is my only means of transportation at the moment. So, going the trailer route will let me get my feet wet, hopefully learn a lot, and help me save some money to hopefully convert a car/truck in the future. I also know there is some concern about jack-knifing with the trailer pushing the truck. But, from looking at projects others have done with pushers, this doesn't seem to be that big of a concern.

Thoughts? Advice?

Thanks

James

I think that would be a first - I have heard of pusher trailers with IC engines used as range extenders - but not as electric pushers!

Good idea.

Possible problems - does your Ford have - power steering - power brakes??

Don't need a lot of power - you could use the IC engine when needed and just have the electric push you when cruising

Jack-knifing - I agree should not be a problem unless you go completely mad on the trailer power

I look forwards to hearing how it's going

The truck does have Power steering and brakes. I was thinking of just idling the engine to provide power for those. I know, not completely electric, but I shouldn't be using that much gas (i read somewhere that the average motor would use 1 gallon per hour idling, not sure how true that is.)

How are you going to get it licensed? Its not a vehicle, nor is it 'driveable'.

If done correctly you can hugely improve the air-resistance with a trailer.

A stretchy cloth to fill the gap and a tapered back end could make it as slick as a Prius. Well maybe not, but way better than a square shaped end.

Its already registered as a trailer, so that wont change.

Trailers do not have engines generally. Atleast not connected to the moving bits.

I think it is a motor vehicle when you add one to the drive shaft.

Georgia (USA) definition : "Trailer" means every vehicle with or without motive power, other than a pole trailer, designed for carrying persons or property and for being drawn by a motor vehicle and so constructed that no part of its weight rests upon the towing vehicle.

So I think it could still be licensed/registered as a trailer.

In a one million dollar question I would gave guessed otherwise.
That is pretty interesting for US citizens. Hope it works out

If you think a small electric car could be used as a pusher trailer with the right remote controls it might not be much more work to use a cheap donor car chassis instead of a trailer frame and then you could also drive it if you wanted.

good luck
