There is a 455 for sale on ebay right now from a GMC- $900 YOU PULL IT.

Seller says he is doing an electric conversion.

He's in Miami.

Anybody here know anything about this project?

Any idea what it would take to move five tons 300 miles with electric motors?

A big trailer full of batteries, and some really good D.C. motors, plus a
very expensive speed controller. Probably best to salvage stuff from a
locomotive or some of those new municipal busses.

But, Jim, when you get to the campground, you can use all 50 amps (12 kw) to charge it back up.

Hope you’re staying for the day and have no interest in Air Conditioning!

Yes, if you have a couple of weeks. And only stay in places with full
electrical hookups. No more camping on Wal-Mart parking lots. Or dry
camping on Federal Forest rustic campgrounds. Think what would happen is
everyone had electric RV's and plugged them in at some of the private R.V.
parks I have stayed in where idiots have wired the plugs. Lots of smoke
coming out of some very expensive wires and stuff.
I think I'll just sit this one out, get out my video camera and a
comfortable chair, a couple of cold ones, and enjoy the entertainment.

If you scrapped about 4 teslas you would have a good start.

I think that's exactly how this will go.

First fleet vehicles will evolve and bring down the price of the battery and motor.

Meanwhile, electric cars will proliferate and guys like we have here will repower old coaches.

That's 530 HP. A lot more than you need to cruise at 60.

But I'd love to know more specifically what the battery and motor would look like.

I've said it before. IMHO the only viable thing to do would be a hybrid.
Stick with a ptrol engine, and add in-wheel electric motors to the rear.
Replace one fuel tank with batteries, and use the e-motors for getting
off the traffic lights and through the city. Use the petrol engine for
getting from town to town.

Heck, I don't know why I didn't think of this sooner. Just put a wind
turbine on the roof, so that when you are motoring down the road at 60 per,
the turbine will supply all your electrical needs. Perpetual motion!. Or,
how about a small portable nuclear reactor. Can't see many problems there.
Think I will just go to the GMC Cascaders/GMC 49ers joint rally at the
GREAT OREGON STEAM UP in July and ponder this one. They laughed at Fulton,
too.

I saw the eBay listing last year and asked that he joined this forum.
I don't believe he did.

Anyhow I don't think a pure electric is practical at this time, but I do think a hybrid would be a good choice to repower.
Smaller gas engine hybrid in front and two pancake motors in the rear. Get rid of the propane and generator set.

I think we are almost there for the capacity. the issue is bringing down the cost.

A Tesla makes over 500 HP with a range of 300 miles and a curb weight of about 5k with a 1000 lb battery.

A gmc with three Tesla batteries and the right motor could get close to that range. Maybe a diesel generator to charge?

Always wanted an over unity machine!

But, in the interest of the back of the envelope.

Assume 10 mpg. 60 mph. That’s 6 gallons per hour (yeah, you’re driving in Nebraska)

Call that 60 hp to cruise.

So, if you had a 100 hp genset, and you used 7 hp for the roof air and power steering, you have 30 hp (21 kw) to charge the batteries when you are on the flat, you might be able to get away with 100kWh of battery packs to push you up and down the hills in a serial hybrid setup. Probably more like 200kWh. Since stored power needs to be described in dollars, that’s $20,000 of batteries (chargers and cooling not included. Your mileage will vary. If you have an erection lasting longer than four hours……… oops, wrong thread).

I’m going to ask some people who really know this weekend (Ford’s hybrid powertrains are engineered in Wheeling, WV - thank you WVU)

I concur… it’s pricey.

The motors used on a mobility vehicle I know of are $16,000 for a pair, sans controllers. And the Batteries. and the genset. All the engineering.

So, $75k for the hard bits, and $500,000 in engineering spread over 1000 units? $125,000 buys a lot of 455/TH425

To retrofit a motorhome to all-electric...

There are two configurations to consider.
1) Electric Motors on the wheel ends
2) One or two electric motors connected to a transmission, driveshaft and axle

Then there are the battery solutions.
1) Re-purpose an existing battery and create a battery bank (ie from an electric car)
2) Develop a proprietary battery

The physical space the batteries need is a concern as well as the additional weight.
A bank of batteries that would be required to achieve a 300 mile range would weigh a few thousand pounds.

The control system, an electric air compressor for the brake booster and suspension, another compressor if you want to retain AC, a cooling system to keep all the electronic devices and motors from overheating would take up the space of our current engines.

There is a training program being developed for first responders, and all high voltage wiring will be bright orange (before it gets dirty)
An electric vehicle fire is very difficult to put out, as of now, fire departments are being told to just let it die out on it's own and monitor it, it usually takes 24 hours....

Don't ask me how I know this Smile

But a wind turbine, solar panels and regenerative braking might let you reduce the batteries by a few hundred pounds.
So who is going to do it first?

You know what happens when you put a 75% load on a internal combustion
engine? Heat! A whole bunch of it. Enough to completely overwhelm the
cooling systems ability to process it. About 18% to 25% load continuous
state is about all you can get away with.
Same goes with electric motors. You work them hard, they fail at about
the same
rate as rocket motors. Almost as expensive, too. That is why you
OVER-ENGINEER the heck out of them. Batteries and controllers, same thing.
Big $$$$$$. Not to say it can't be done, but get out your billfold.

Don’t confuse kWh with kW

You need to deliver 60 hp over time, plus grunt to go up hills.

Compare that to the 9 hp or so it takes to push a Tesla down the highway.

Dave:

Have you been around a Tesla on a “Supercharger”. It’s rock concert loud.

Second, go drive one. I killed half the range in a 15 minute test drive. I unleashed a lot of those ponies.

Much of what we are talking about, like the wind resistance of the coach, is non-linear.
