Harvester

[Chavannigans]

One of the more popular Kubota generators is the GL7000. It provides power similar to lower end level 2 EVSE (chargers). It is pretty damn heavy as I have seen them in the back of pickups plenty of times. So, this gives you an idea of what it would take.
The Kubota GL7000 is a 7 kW (7,000-watt) liquid-cooled, dual-voltage (120/240V) industrial diesel generator designed for quiet, reliable, and compact power. Powered by a 2-cylinder Kubota Z482 diesel engine, it features a 7.4-gallon tank with up to 10-16.5 hours of runtime, one-side maintenance, and safety shutdowns.

Dimensions L x W x H (inches)	1066 x 618 x 698 (42.0 x 24.3 x 27.5)
Approx. Net Weight (lbs.)	235 (518)
Sound Level (Full Load at 23 ft. [7m])	66

​

The Kubota V1505 can produce 25kW at 3,000RPM and weighs 243lbs.

Its 23.9"H x 22.3"L x 15.6"W

Then add the generator for a total of around 320lbs.

Spline the little diesel into a DC permanent magnet pancake generator that are usually good for 95% efficiency. Then that is wired to a voltage controller and into a 15kWh LPF battery with 3C cells wired in series parallel.

That LFP would weigh around 250lbs and eat up more payload but would clean up and stabilize the voltage, as well as offer a battery that can power things at camp without the truck being on.

A 32 gallon fuel cell could theoretically push range to 680 miles at 70mph (.48kWh/mile) or over 800 miles at 60mph (.40kWh/mile).

An OEM removable battery pack would cost a minimum of $10k and likely up to $15k-$20k, the same as the Harvester (I’m guessing).
Brand-T promised such a thing for the dumpster, but it failed to materialize.

Scout would sell a dozen of them and would never make back the engineering investment cost.

But… And don’t let Scout’s engineers see this or they’ll figure out a way to make this impossible…

If they’re engineering the BEV and the Harvester to be nearly identical, there is possibly going to be either an AC power line from the Harvester to the onboard charger or a DC power line from the Harvester’s converter to the battery…

Buying a BEV and then tapping into that line (after your warranty is expired and you’re willing to park a good 100 meters from your home), with an auxiliary aftermarket battery doesn’t seem impossible…Who knows what internal software reconfiguration would be required…

Tesla abandoned their Cybertruck bed mounted battery. If they can't do it I doubt any other manufacturer will either.

Kubota is engineering for longevity and regular use. Westinghouse’s big box store generators are for people who will use it two or three times in its lifetime.

Our kubota tractor always ran amazing

Would you like to have that set up in your Terra?

Nope. My fat a-- already eats up too much of the payload as it is.

We also carry a LOT of crap when we travel so I can't give up all that bed space.

If I did an Arctic trip in a truck instead of the motorcycle, it would definitely consider building one though.

Just having fun with possibilities.

Better to just put in BIG battery in the Terra instead any of this stuff.

Assuming you can charge at a Level II or Level III charger in the area you need the extended range, sure.

Yes I agree a slide in battery would be to heavy. What was i thinking. Just need 420 miles and I am good.

 

[SpaceEVDriver]

I have no interest in a huge battery nor a slide-in battery. And certainly no interest in any kind of fossil fuel engine-run generator.

I would enjoy having a battery in a travel trailer that could hook into the system via a cable on the trailer and to be able to provide trailer battery power to the system while driving.

For us, 350 miles is ~10% more than we have now and it’s more than enough for almost everything we have ever wanted to do. 3300-5000 mile road trips are easy with 320 miles range. There’s one spot that’s currently closed due to wildfire damage that I would like to be able to do without charging. It’s 410 miles round trip. With a 350 mile range, we would be able to do this trip with some solar to recharge while we’re camping.

See I have to get in this mindset. We went to Chicago about a week ago. About 260 miles round trip and I keep thinking oh when I have my BEV I’ll have to charge somewhere along the way. Don’t want to get too low on power, but I should come home with 90 miles left. I don’t know why it worries me so much.

You will want to NOT charge. Unless you can find a free Level 2 charger wherever you go in Chicago, it’ll almost certainly be cheaper to charge at home.

 

[dleepnw]

Removeable? That's asking a lot. I just hope its efficient and works as advertised.

Range anxiety but the more we grow to believe this cult the better set we’ll be when we get our BEV. Then we’ll meet out in a big field at twilight and have a KoolAid party

I know its really stupid, but the iPhone Air experiment helped me overcome this anxiety, well most of it.

I am looking forward to the BEV marshmallow roast.


I know you're kidding, but it would be really cool if there was an EV only off road rally event that included vehicles like Scouts, Fords, Chevys, and Rivians.

Edit: I guess Cybertrucks can come too

Like that idea. And if CT has too it’s being good neighbors

 

[mastertroll]

I’m questioning why you’d want it taking bed space when it could be under the vehicle other than a bit of tow weight but I’m expecting BEV anyway so I don’t particularly care
Welcome!

Aww I see now... The reason you would want to do this is because the performance and handling remains what EV enthusiasts would expect. Add the generator when you want to go far or charge off grid, remove it when you don't need it. Try driving a rav 4 hybrid and then a non hybrid.. you'll see the difference.

If you have a BEV and want to take a portable generator to go off road for a week with fuel cans, by all means-not arguing that. But if you are thinking the gen is strapped in the back as you suggested earlier and plugged in adding juice to the vehicle while you are doing 75 down the highway it simply isn’t practical. @SpaceEVDriver has provided plenty of science on why this doesn’t work. I would also assume SM could just source a Honda generator or similar and license it rather than becoming portable generator manufacturers but to each their own.

 

[SpaceEVDriver]

The manufacturer could design a removable generator to fit in the bed of their truck and provide some sort of plug that allows charging while driving—they’re in charge of the engineering and programming, and this isn’t exactly impossible. It is far more difficult for us DIYers who want to do aftermarket add-ons.

But the nightmare of maintenance, warranty, safety, and legal issues they would face is likely to be overwhelming to the point of making it not at all worth the cost. This is especially since very, very few people would want to purchase a 300-400 pound bed-shaped generator for the few times when they’re going on a long trip. People want simplicity. Even a much simpler device like a consumer-removable battery is something I cannot imagine a vehicle manufacturer wanting to take on the liability of warrantying. How can they be sure the consumer doesn’t abuse the device when they remove it?

Also, Scout has been very deliberate about designing the Terra and Traveler to be as close to the same “under the hood” as possible. Having a complex removable charging system in the bed of the Terra would preclude the Traveler from having that range extender. Or the Traveler would have to have the Harvester as it's being designed. And at that point, why add extra cost, complications, legal, engineering, and warranty with another kind of gas genset instead of just using the Harvester in both the Traveler and the Terra?

If they were only building a pickup truck or the platforms for the Terra and Traveler were distinct, it might be something they would consider. And then they might look at the failure of the in-bed battery for the CT and conclude that it’s not worth the cost for a new company to take on.

I guess I’d probably be considered one of the “impractical” ones. I used to transport a Delta Pro Ultra around, so the concept isn’t that strange to me. The bigger issue is that if Scout doesn’t provide a way to hook something like that up, it essentially eliminates the ability to travel long distances using a modular generator approach. What will happen instead is people will start doing it in roundabout ways—adding external plugs and hacking software just to make it work.


The real solution would be for Scout to offer larger battery options, like 150 kWh or 200 kWh packs. If we’re talking about practicality, the whole vision behind Scout is off-road exploration and adventure. That becomes difficult when you’re far from infrastructure and there’s no way to charge.


If Scout sticks with a 130 kWh battery (EV-only), which is similar to the Lightning, the realistic range is around 250–280 miles on average—and that’s before you’re already thinking about finding the next charger. Sure, you can run it to 0%, but the 350-mile range figure is more of a paper number than a real-world expectation.


That’s likely why they’re offering the Harvester model, but that comes with trade-offs in towing, handling, and overall performance. The third option is a modular generator setup—really feels like the best of both worlds. Both worlds being.. When you don't care about range, you just drive like an EV. When you wan't to go far/off grid. You take it with you.

If Scout doesn’t build it themselves, people will end up creating their own MacGyver-style solutions anyway. Being able to remove the generator when you don’t need the extra range would be a big advantage. Bare minimum offer the plug in the back of the bed so people can extend range if they need to (emergencies etc).

The Lightning wasn't designed to do this FYI..
