The point was that it's unclear to me that currently-produced EVs will even **move** if everything turned off. So I wanted to hear from people who have looked into the variation across current models in this "dependence" factor.

you're right - if you can't **currently** get gas you likely also can't **currently** source a bunch of solar kits. I was talking about a prep scenario. (and even so... i bet you could jury rig some wind turbines and a large array of scavenged car batteries - but you'd still need a motor to spin your car's wheels, and that's not going to be an ICE motor in that case)

I drive an old EV. I have wondered about charging it via wind turbine and/or solar. It isn't straightforward. You would need to generate a good amount and then run it through an inverter.

DIY solar charging for an EV involves setting up solar panels, an inverter (to convert DC to AC), a charge controller (for battery health), and potentially a home battery for storage, connecting to a compatible EV wall charger to use the sun's energy to power your car, with systems often needing 8-12 panels for regular use. While basic setups can trickle charge using a "granny charger," a dedicated wallbox or smart charger offers better efficiency, especially with excess solar power, and some systems allow grid backup when needed.
