>>>"Personally I haven't run out of charge in 4.5 years of driving an EV in all sorts of places" Neither have i, but if the cybertruck is any dystopian-minded-MadMax types' "bug out vehicle" -- this is going to suck. The cybertruck should come with a built in generator that can consume gas to charge your thing? One can take a cybertruck-type vehicle out into the woods of Alaska, and carry a bunch of extra fuel, but you can't bring an additional 5,000 LBS of batteries... I' dont have the energy (pun intended) to do it, but it would seem that one could make a simple spreadsheet to compare miles per gallon to miles per battery weight, such that you know that if you get 20 miles per gallon and a gallon weighs 8 pounds, vs you get how much distance out of the EV per weight?

Where will you find refined unexpired gasoline in your MadMax apocalypse? A pack of solar panels you can set out in your bug-out camping zone seems more feasible to me. No dependency on ongoing supply chains. Just look at how quickly gas shortages start when a hurricane is aimed at Florida. And Tesla does sell a bolt-in range extending battery pack for their truck for $16,000 https://insideevs.com/news/699262/tesla-cybertruck-range-externder-weight/ https://insideevs.com/news/699262/tesla-cybertruck-range-ext...

    Depends on how long you can wait to charge. 10kW seems like a capacity that could be carried in the truck bed and then set up on flat ground while camping out. A realistic daily average output would be 30-40kWh in a day, or about 1/4 of the truck's battery capacity. Sunny days in summer would do better, cloudy winter days would do worse. Recharging fully in 5-7 days seems reasonable. Assuming you actually had drained the battery to near empty and were needing to charge it back to full. By some comparisons that seems slow. But it might be faster than waiting for a gas truck that never comes.

> The cybertruck should come with a built in generator that can consume gas to charge your thing? This is called a "plug-in hybrid". [Depending; some, like the Chrysler Pacifica Hybrid, have a dual drive train so the engine is an engine; others, like the Chevy Volt, have an all-electric drive train and the engine is just a generator.] In you're post-apocalyptic setting, you're looking for a solar panel array you can tow behind your electric vehicle to charge it periodically; you wouldn't be able to haul a large enough array to charge at the rate you deplete your batteries, on the go, and depending on the size of your panels and your battery and the weather it make take several days or a week to reach a full charge, but where are you going in a hurry at the end of the world?
