If you're thinking of EV charging as it's commonly portrayed in the media ("You have to go to the fast charge stations and wait, or you have to have, like, 700A service to charge your 300 miles in an hour overnight!"), yeah, there are problems. If you talk to people who actually own and use EVs, almost none of that matters, because slow charging at home overnight is what people do, and it simply doesn't take much power. The average American drives about 35 miles a day, which on an EV is about 10kWh. Maybe more in the winter, but if you charge on a 3.8kW charger (240V/16A), that's only 2-3 hours of charging at home. You can charge on less if you want, or even on 120V and be fine most of the year, but winter will be a problem in some areas - you're using more power for heat, and the car has to warm the pack to charge in the cold, so 120V may not deliver enough power to both warm the pack and charge the pack. It's not impossible, but you make your life a lot easier with 240V/16A charging (max continuous current on a 20A circuit). DC fast charging is only needed if you don't have a place to charge at home or at work (which will be the case for plenty of people right now and hopefully fewer long term), or for long road trips (also a fairly rare case). My preferred method for EV charging infrastructure [0] is to simply put those 240V/20A chargers everywhere. Apartments, shopping parking lots, etc. Your car is "grazing" in enough places that it's never a big problem except for road trips. If it's not full, oh well, it'll be filled up next time. I can do 100 miles a day on a Chevy Volt (10kWh battery pack before the gas engine kicks on) purely on battery if I'm going between places that have chargers, and have some time at home to charge, etc. Now, are there problems with sourcing the raw materials for batteries? Yes. And this is why I'm a fan of PHEVs (40-50 mile battery range, gas engine for longer travel) for the next decade or so of vehicles, because you can put a given number of cells into a lot more cars that way (you can build about 5 Chevy Volt packs for the cells going into a single long range BEV), and that offsets far more gas use, while also being less annoying to use - if you can't always charge, it's no problem, you just have a hybrid. In terms of additional power needed, because EVs are so much more efficient than ICEs (about 85% wall-to-wheels vs 25-30% on an ICE), you only end up needing about 25% more annual power production. There are some peak demand concerns here, but they're fairly easy to mitigate as they approach - peak demand increases from population growth anyway, so it's a "Build out peak capacity slightly faster than you were planning to" concern for power companies, not an overnight panic sort of problem. And while you're at it, EV charging after the morning commute can take up a lot of the mid-day solar surplus. 0: https://www.sevarg.net/2020/04/27/slow-dumb-charging-quit-charging-for-ev/ https://www.sevarg.net/2020/04/27/slow-dumb-charging-quit-ch...
