gas generator trailer for EV's

Sun Jul 24, 2011 12:45 pm

I found this on the Tesla Motors Club forum. It's a way to convert your 100% EV into a Volt for longer trips.

I've been toying with the idea of a cross-country tour and was thinking I'd carry a small generator with me in case I was "between" charging stations in the middle of Texas or New Mexico.. I could pull over and run the generator for a few hours and get some more miles of charge. I really had not thought to run the generator while driving (if the Leaf could be coaxed into that)...

The Volt engine produces 53 kW which is not sufficient power for peak situations and 20 kW seems a long way from 53 kW. Does this thing control pollution and emissions?

This is a really clever idea. Think of it as a Volt where you can leave the gas engine, gas, gas tank and exhaust in the garage the 95% of the time you don’t need it. Less weight and more space for batteries or cargo.

As to the 53kw being insufficient, If you could get 3 miles per kW, a 20 kW generator will sustain you at 60 mph until it runs out of gas.

And to the emissions question, it is easier to control emissions on an engine that runs at a constant speed.

From a purely engineering standpoint, yes, but given the amount of gasoline burned by cars vs. portable generators, the emissions requirements that cars have to meet are more rigorous. While they may exist, I haven't run across generators with catalytic converters, exhaust gas recirculation, evaporative vapor recapture, O2 sensors, etc. etc.
I noticed you're still working with polymers.

The whole concept seems rather silly to me. For my cross-country trips, I'll drive the Prius. Lifetime mileage is 49.5mpg over 44,000mi. Dragging a 350lb trailer with a noisy gasoline engine certainly can't be good for you or your Leaf. Also, in many states, speed limits are 55mph for autos pulling trailers. Backing up and/or parking will be a PITA. :roll:

My wife and I were talking about this same thing yesterday.
The disadvantage of having to haul around the gas engine when you never need it.
I would go for this as an option.

Better than buying a plug in :)
probably would not cost as much as the DC Port option

Not wishing to throw a wet blanket on this topic, but the LEAF Owners Manual, page 9-14, specifically states:
Do not tow a trailer with your vehicle.

while page 9 of the LEAF Warranty includes:
GENERAL EXCLUSIONS
This warranty does not cover damage, failures or corrosion resulting from or caused by...Misuse, such as overloading, using the vehicle to tow, driving over curbs, or using the vehicle as a power source.

Oh, and as others have so succinctly said, "It's silly!"
