So I need to build a new trailer for work and I'm thinking of finally trying my hand at EV propulsion.
The tow vehicle in question weighs 1400kg (~3000lbs) and the trailer should come in at under 300kg (~660lbs - minus the electric drive system). It's used 99% of the time in city traffic, I don't need the trailer to be capable of any more than 70km/h (~45mph)
I don't expect the trailer to drive the car as such, I'd like it be able to move the car with the engine off in traffic and assist in EOC distances. Ideally, I really want regen braking, as in city traffic (some days less than 15mph avg speeds) that would help a lot.
So I'm thinking of using a big R/C aircraft motor, something like this:
Turnigy RotoMax 150cc Size Brushless Outrunner Motor
It puts out 13hp and can be had for around $400. I could use an R/C controller too (around $300) if the currents can be contained, maybe not likely. The way I see it is even if I needed to use two of those motors, $1400 for 26hp with controllers would still be economical).
Does this seem like a possible way to power my trailer, or would I be better off sticking to something more like a golf cart/ forklift motor etc.
I don't think any of these options allow regen, what's the cheapest way to do that?
Just thinking out loud, any input appreciated
