Curious
What if I carried my 200lb, 7200W, 240V/30A generator in the truck bed. Taking that same 350 mile trip, and say a realistic distance is 250 miles per charge. Let's say I travel 200 miles and stop at an out of the way location to take a lunch break. Out of the way meaning generator noise doesn't offend anyone. How long will I need to recharge at 7200W before I can reliably make the last 150 miles?

Ford hasn't officially listed the battery size but based on charging estimates from Ford, it's around 150kwh of usable battery bank.

That's about 2 miles per kwh to get 300 mile range. A 7.2kw generator running for an hour might add 14miles (might be a little less depending on efficiency). This presumes the generator is rated for 7.2kw continuous output and the onboard charger won't be limited to some lower charging rate.

So if you crank up the generator and plug it in just before pulling out of the driveway...assuming you are running at 65mph, 350miles will take 5.4 hours. Assuming the generator is in the back running the whole time at max output, that will give you the 300mile battery range plus an extra 75miles from the generator for a total of 375mile range...ie: you have 25 miles left when you arrive.

There are probably some errors due to efficiency losses, so figure you will be limping in on the proverbial fumes. Keep in mind 7.2kw is roughly 10hp. A full size pickup at freeway speeds is likely drawing 60-80hp to keep up the speed.

Umm, I think the biggest error in your calculation is the fact that EVs can't be driven and charged at the same time....

Every plug in hybrid does exactly that. Though they typically have a far bigger generator than 7.2kw.

If you are going to take a battery only EV and rig it to charge with a generator in the bed, of course, you are going to have to make some modifications. If they have a system that stops charging while the vehicle is in motion, you will have to bypass that system.
