If the power demands of the vehicle are greater than the generator can provide, the battery will lose charge and thus power would need to be restricted to keep the battery from dying.
I’m not familiar with how this hybrid system will work. Is that what happens? You can drive no faster than the generator can charge the battery?

We can only theorize based on how other EREVs work - but yes, when the battery reaches the point at which the generator is utilized to keep the battery from dropping any further and charges it - if you are using more power than the generator can provide and the battery loses charge, you may end up going into a limp mode where your power is limited.

So then the Harvester option isn't an option for when you're moving at say highway speed. Unless it can charge the batteries faster than they are being used, it would only be good when stopped or at very low speeds. Do I understand that correctly?

It all depends on how they plan on sizing the engine/generator combo. I would assume they are targeting it to be able to provide enough power to drive at highway speeds without too much trouble but we have to see.

It's a voyage of discovery lol

A line to get gas? Where do you live, the 70s? :angel:
Buc-ee's have lines at gas pumps because they have this odd cult following, and all the knuckle dragging gas pump parkers who leave their vehicle to get their super sized sweet teas, 2 pound BBQ sandwiches, Beaver Nuggets, and XXXXL Beaver shirts.

They have a unique charm and I occasionally get gas at one, only at 2 am on random Tuesday nights when it isn't a circus.

CT, Lightning, R1T, Silverado EV, are all right at 2mi/kWh at 60-70 mph, add a trailer of any size and it goes down to 1 mi/kWh, up an extended grade an it goes down to 0.5 mi/kWh, so a generator needs to be 60kW just to keep up under normal towing mode 120kW under extreme demand add in 10% AC to DC loss and you’re right at 130 kW which is what Ram is saying for the Ramcharger.

I read that BMW reduced the size of the range extender fuel tank on the i3 in the US (vs Europe) because if the gas range exceeds the all electric range, it gets reclassified as a PHEV. I don't have a source, so take with a grain of salt
Close. They limited its effective size in software, meaning there was still 1/2 gal. of fuel in the tank when it when the car said it was empty. Source: I own an i3, which I've coded to make the entire fuel tank usable, which is still only 2.4 gal.
