It has been mentioned in other threads.

This also gives me a generator that can be used for other purposes.
  • Emergency power for the house (limited number of devices, mainly fridge and tv)
  • Power supply when camping.
  • Portable power for power tools etc.
  • An emergency charging source if the EV gets stranded somewhere away from utility power.
I like your maths Astro; it should work out roughly the way you figured it. The problem I see is charging the vehicle while operating it. My PiP will not allow the vehicle to be driven while plugged in, and I'm sure all cars are designed this way.

The first problem to tackle is having an over-ride mode that allows the car to charge and drive at the same time.

Once that is figured out, I'm sure a generator could be added to extend range.

I too like the idea of making things modular and versatile. A generator that can perform all of the tasks above makes it much more valuable.

I'd like to see batteries become more modular so that individual banks can be added/removed from a car, and added/removed to a motorcycle, lawn mower, leaf blower, chain saw, etc. The cost of ownership of all these items would be greatly reduced if the same power source could be utilized.

A generator only makes sense as a range extender if it's also used for other purposes. If the only purpose is to extend range, then a gas pusher makes more sense.

6 kWh generator
