Switching Harvester to All EV Model?

[cyure]

I've been thinking about making that switch at some point too. Both models seem to be very capable but the simplicity of a full BEV seems a little more attractive, I think it'll just be best to wait and see the updates scout provides as we get closer to launch date and the improvements to EV infrastructure throughout the country.

I think what I'd need to see to fully commit to the Full BEV is lucid levels of efficiency, which might be a myth lol it does not seem like any manufacturer can get close just yet. hopefully scout can figure out what lucid has going on because north of 3.5 miles/kWh would be a dream.

I’m in the same boat. And my understanding, someone correct me if I’m wrong, is that it’s not necessary to change our reservation to the BEV and when it’s time to order we can change even at that point. Is that correct? Because I am totally undecided at this point in time.

"is that it’s not necessary to change our reservation to the BEV and when it’s time to order we can change even at that point."

That is my understanding as well. However, once you have Scout's equivalent to a DORA (Dealer Order Receipt Acknowledgement) changing things could be more difficult.

Thanks for the confirmation. That’s the way I understood it as well.

I think you are correct that the BEV version will be way less complicated. It will be a good choice for many if not most including me. I share your hope for 3.5 m/kWh, but aerodynamics and tires will play a big role in making that difficult. I have a BMW iX that has a drag coefficient of 0.25 Cd. That is really good for a vehicle of its size. I average 3.2 m/kWh if I use Efficient mode. I do run performance all season tires instead of the summer tires that it came with. That switch hurt my efficiency a little, but worth it for wet traction and cold weather safety. For what it's worth the Rivian R1S has a drag coefficient of 0.28-0.322 depending on who you ask.

I'm dubious about anything exceeding 2.0 miles/ kWh (ON AVG)... The Lucid and BMW comparisons are very different. When looking at the Terra or Traveler, the tires and wheels are much heavier, the shape is much boxier, the heights are much taller and there is more air moving underneath, over and around the box creating more friction. Overall, curb weight will be vastly different when comparing to EV cars. The R1S comparison is good, b/c I am guessing the the Scout may be slightly less aerodynamic. Of course this is all speculation again, until we see some real-world testing. In my R1T, anytime I am getting over 2.0 I am happy. I don't drive it conservatively or different than I would drive any other truck. If I drive conservatively, stay under 70MPH, use only 2 motors in Conserve mode and have warm temps and no wind or weather, then yes, I can get above that 2.0 mark pretty easily. Driving downhill? No problem, but in the real world where I live, we have winter, we have weather, we have elevation changes, and I drive the truck like a truck. 2.0 is nice, 2.5 would be amazing on average, 3.0 seems like perfect conditions would need to exist.

To be fair, it’s warmer where I live and it’s flat ground unlike where @R1TVT lives. But I suspect that more people will see numbers closer to the 2-2.5 like he is seeing. Yes, my BMW is not a direct comparison in any way to the Rivian or Scout. But, here is my April efficiency for reference.

 

[Chaz26]

I agree that there's no way Scout's are getting anywhere near to Lucid levels of efficiency, pretty much impossible based on their design. I'm thinking for highway driving in the Terra, it's going to be around 2-2.5 miles per kWh. I still hope the BEV option will have about a 150 kW usable battery (or more) just to make sure it can get a 300 - 350 mile range during normal driving conditions.

 

[SpaceEVDriver]

Anything above 2.5 mi/kWh for the EPA average is a pipe dream. Drag is, by far, the most important factor, and you can't make these bricks any slicker.

EV Truck Miles per kWh (epa range divided by battery size, ignoring charge efficiency):

• Ford F-150 Lightning: Approximately 2.44 mi/kWh (based on a 320-mile range with a 131 kWh battery).
  
  
• Rivian R1T: Around 2.23 mi/kWh (based on a 401-mile range with a 180 kWh battery).
  
  
• Chevrolet Silverado EV: Around 2.12 mi/kWh (based on a 450-mile range with a 212 kWh battery).
  
  
• GMC Hummer EV Pickup: Roughly 1.48 mi/kWh.

Agreed

If you equipped your trailer with the appropriate amount of solar and battery you would have the option of not having to use the Scout battery while camping. You may not hear your Harvester while driving but surely you would while camping and connected to your trailer. You could always separate scout from camper while camping. If you choose a Terra I just wonder if you could just go with a DuroMax 9000 with external gas tank generator (50 amp output for level 2 charging over night). Only bring when your on a long camping trip. My hope is the Terra BEV will have 400 mile range (200+ with trailer). Most places I camp are less the 100 miles from super chargers.

I have a set of solar panels that we bring with us when we camp for more than a couple nights.
I also bring a 5 kWh power station (like a Bluetti, but generic) that can power our fridge, our hot plates, coffee pot, etc.
None of those appliances take a ton of energy. Those that draw high power don't run for very long, and the fridge doesn't draw high power, so I usually don't lose much of the power station's battery on any given day.

I can recharge the 5kWh power station with our 400 watts of solar very quickly here in the southwest, usually by the middle of the day during camping season.

I then plug in the truck to draw down that 5kWh power station until it's at about 10-20%, which usually doesn't happen until late evening. The 10-20% is enough to run the fridge and cook breakfast. The 80% (4 kWh) I draw out of the power station goes into the truck's battery. The next morning, the power station starts recharging. Silently.

If I'm camping for 4 days, that's about 16 kWh, or a little over 12% of the truck's battery. With a realistic 320 mile range when I'm not towing, that's about 40 miles extra range, or 10 miles per day gained passively. And I don't have to listen to a generator or a truck engine.

If we get a travel trailer again, I'll mount the solar on the roof of the trailer and won't even have to think about it. And I'll be able to double or triple the amount of solar I bring with me, which will allow me to be charging the truck during the day. If I can fit 1200 watts on the trailer, then I'll be able to replace what the truck is drawing during peak sun. So I'll be able to add 15 to 20 miles a day to the truck.

Regarding house backup: The Lightning has 130 kWh battery, and you can expect something like that in the Scout. Your house likely only uses around 30 kWh a day, so if during an outage you ran at full power, you could go for about 4 days before you needed to recharge the truck. But if you're in a power outage situation, you might decide to cut back on energy use quite a bit. The last time our power was out, we happened to not need AC or heat, so we just ran the fridge our computers, and the various internet services (we work from home). We ran on the truck for 10 hours and used less than 5% of the truck's charge. Extrapolating, we could go for 200-ish hours (8.3 days) without AC/heat. If we need AC or heat, it will bring us down to the 4 day timeframe.

I came across this yesterday in a Rivian thread and though yall might find it as an interesting option.

This would cover most of my 34 mile commute and I love the fact that it can protect glass roofs.

Would just about relieve all range anxiety out in the boonies if weather is optimal too.

That's basically what I do, without the fancy rack and extra wind resistance.

That one can still charge when you are driving so I guess that would be a key distinction. I am not sure how much wind resistance it would create though. I would be interested in that data once it comes out.

Sort of.

Note that one of the videos shows what it’s actually doing: charging an accessory power station, which is then used to charge the vehicle. The same as what I do.

Just 3 or 4 panels cannot generate enough voltage to charge a 400 or 800 volt battery.

That’s interesting for a bit of energy but I’d be worried about the moisture seal leaking over time with the charging cord needing to go into a trunk and being compressed over time. Otherwise if you camp or live in AZ this would be worth it to some people

Hopefully Scout gives us some bungs on the roof for light bars and other roof mounted accessory wiring.

 

[R1TVT]

Anything mounted on bars on a roof will be detrimental to range. With the Terra, there is an interesting opportunity with the pick-up bed to seamlessly integrate a solar tonneau... This would be an interesting option to consider for truck owners, or if you wanted to eliminate the large glass roof and combine a solar roof with a solar tonneau. Still not really enough power generation for anything truly revolutionary. but interesting for camping or accessories or when leaving the truck unattended for long periods.

[Dasher]

Is anyone that has reserved the harvester model considering switching to the all EV model? Especially those that live in California?

Nope, if anything, I'm hoping they change to a plugin hybrid with gas and hybrid power combined with a 500-mile range.

On a truck none of that is a concern since everything can be in the bed and one can purchase relatively water-resistant power stations and chargers.

If I were doing this with an SUV, I’d run the DC lines through one of the many rubber-sealed entry points like at the (equivalent of) firewall. For the output to the J1772 port, it’ll be more difficult to find a large enough entry, but hopefully there will be at least one. If not, one could just set the power station outside while charging.
