The elephant in the room when it comes to EV’s is the dirty batteries they use and if they can be recycled cheaply.
If they can make them to where they charge in a few minutes, say the same time it takes to fuel up a vehicle with gas or diesel today, then a gradual organic phasing in of these vehicles makes sense.
What doesn’t make sense is to ban ICE vehicles. That will take generations. Many places around the world don’t have full time electricity now so they will likely be using ICE vehicles well into the 22nd century.

600kw will take a standard sized Model 3 pack from zero to 100% in 5 min. The NACS plug has a max rating at V4 of 900 amp uncooled at 1000 volts or 900kw Tesla has tested the plug at one megawatt already and it stayed under the 75C heat limit. The limit is what the cells will take. 600kw into a 50kWh pack is a 12C charge most cells can do 5C with some new tech going to 10C continuous with active liquid cooling of the cells. 5-8% is lost to heat with DC charging at 500kw that’s 40kw in heat you need liquid cooling for those kinds of heat loads per sq cm of surface area. At 12C liquid is the only way to go.
