Ok , this may seem crazy, but I have seen diesel generators run for very long periods on small amount of fuel.
Why not have a small diesel generator to run an inverter to charge batterys at any time they fall below a certain charge?
Mostly when running .
Only thing you need to do is fill a small diesel tank on your vehicle once a month for small amount.
Just a fun thought !

Seems you will need a rather large gen to provide enough energy to both drive the motors and at the same time to charge the batteries.

That would be a plug in hybrid. Plenty available. Although none diesel that I know.

The Volt’s engine moved the car but it didn’t charge the battery. Insufficient size to power an adequate charger and power the car. GM tried.

I assume you mean similar to diesel electric locomotives where the only motive power is from electric motors with electric power supplied by diesel generator.

I would guess if it were feasible someone would have already tried it.

hybrids bring the best of both worlds. But, they cost more than ICE, and pure electric costs more than Hybrid. Customers in general have been unwilling to pay for the technology change.

That would be a series hybid, like a locomotive.

No reason you couldn't do it. Pretty sure any factory EV would not let you start the car while plugged in so you'd have to do some electronics trickery.

Unless you are talking about charging the batteries only when you have the vehicle parked, you need a generator the size of the normal engine, Plus a few percent larger in order to account for losses.

Weight. The diesel weighs more, the enemy of electric or hybrid cars.

If you need say a 150 hp gas engine to move a car, you would need a 150 hp generator to produce enough electricity to power the car. There are no freebies. I guess you could park the car for two days while a tiny generator charges the batteries back up.
