so I could go on a Cheap Car rally across all of Eurasia. How would I calculate how much power I would need and how bad of an idea is it?

you would need to know average consumption in kwh and then size the genny to match plus a large (20%?) margine on top. then figure it if
a. it will let you charge and drive at the same time.
b. handle the thermal load of charging continuously
c. how much current you can put in... you could buy a huge genny but it might current limit and bottleneck you at the car.
then you'd have to decide if a generator that size would be cost effective.

i would figure around 2
00 to 3
00 whr
/ mile. you'd be looking at 20kw to maintain highway speed.

My Leaf uses about 15kW at 60mph on the flat, according to its onboard monitor. Add some charging inefficiencies and enough overhead to recharge the battery after some hilly stuff while still driving, and you’re looking at maybe 30kW.
I bet most if not all EVs won’t drive while charging though, because they’ll want to prevent you ripping the plug out of the wall.

Yes. For example a 120v 20 amp household circuit is good for maybe 2hp.
