This is very positive news and we're having some interesting times ahead. It will of course take several decades before the EV replaces fossil driven vehicles, but they need to start somewhere. I don't see any issues at all with powersupply and there is plenty of time to ramp up production in parallell. Also most EV's will be charged during night time at home and during night power usage is much lower and the overcapacity will be utilized.

Since a Tesla can be charged about 300km in 30 minutes running their Superchargers on a 145kw power network it really looks good with this network based on 350kw power. "Filling up" 300km in about 10-15 minutes stop over is very good and for those who don't spend the entire day in the car this is more than acceptable. And why not have a 10-15 minute coffee brake each 2nd hour anyway?
