no it isnt… what the fuck are u talking about that generator has an extra shitty ice engine in it plus the losses on the generator, batteries, and motors. its way less efficient, theres no need to lie, EV are marginally better than ICE cars even if u dont lie about extreme edge cases like this.
So I’ve heard this lots of places but never done the math, so I sat down this afternoon to try and work it out and…it’s super complicated. The generator in the picture might not charge the car at all…if it is, it’s probably a trickle charge like plugging into a 120v outlet…which means running the generator for a very long time for a very small charge which means it’s super inefficient…depending on your starting assumptions you get anywhere from 11 - 20 miles of charge out of a gallon of fuel for the generator, which is less efficient than tha average of 31 mpg for a 2022 sedan…so in that case, it’s less efficient. The more normal use case would be a whole-home generator powering a level 2 or 3 charger in your garage… which can be more efficient than an ICE engine assuming a high-efficiency generator and EV. Additionally, generators don’t typically have emissions controls, so from a carbon standpoint, it’s WAY worse than an ICE with a catalytic converter.
Also of note, this is still more fuel efficient than using an ICE vehicle.

Yes, I have read that it is. The generator runs at most efficient RPM and doesn’t have idle time, etc.
