Hello!
I plan on buying the Range Extended Models only, as it makes the vehicle more capable and usable. However I have been curious about the possibility of letting the harvester idle to recharge the battery pack while camping or parked etc.
Using the Ram 1500 Ramcharger as a baseline since it's the only vehicle with public specifications, I have done some calculations to see how much power the Scout Harvester’s generator will realistically produce. The Ramcharger’s 3.6L engine makes 202 kW peak, and its generator can put out 130 kW continuously. That works out to a real-world mechanical-to-electrical efficiency of about 64%.
If we apply that same 64% efficiency to the Scout’s expected 2.0L naturally aspirated four-cylinder, we start with a typical output of 110–130 kW peak, and around 85–100 kW continuous. Using the formula
Pₑ = Pₘ × 0.64,
85 kW becomes about 54 kW, and 100 kW becomes about 64 kW. So the Harvester is realistically looking at 55–65 kW of continuous electrical generation.
So How Long Would it Take to Recharge the Battery at Idle at a campsite etc. AND how much gasoline would be needed to do so?
The battery capacity Scout has confirmed is 60–70 kWh, I picked a middle value of 65, Charging from 20% to 100% (Because some battery will be reserved for hybrid operation/system output) means filling 80% of the pack:
0.80×65=52 kWh0.80×65=52 kWh required generation, However charging results in losses so (90% efficiency)
52/49.5≈1.05 hours≈63 minutes to recharge
33.7×0.23=7.75 kWh per gallon , so 52/7.75≈6.7 gallons to replenish the battery pack.

Curious to hear others thoughts / or calculations! Planning on seeing the Scout's at the LA Auto Show!

Ok, you math more than I do so I'm not really criticizing or anything. Just trying to follow. Where'd you get 64%? Just taking peak to continuous?

And where'd you get the 110-130 peak and 85-100 continuous?

Cause if you just take the 85kw continuous...isn't that 85kwh in 1hr of charging? So that'd fill a 85kwh battery in 1hr (Yea there's losses I don't want to match right now).

The other wildcard here is Ram had mentioned somewhere that it'd only fill the battery to half. Iirc it was TFL who speculated that was a voltage limitation. So I have no idea if scout will have the same issues or limitations.
