Imo the way things stand things are already good enough as they are.
we don't need to double battery capacity/distance or even charging speeds, it's a massive waste of resources that won't benefit the vast majority of people.
from quick google
so even if you have a 200km worst case scenario range on your EV, unless you are one of those people that are on the road a lot, it literally covers like 99% of your car usage.
Hyundai EVs charge with 350Kw, to 80% in like 15m which is perfectly fine for a longer roadtrip imo. I used to travel 200kms every two weeks and in most cases I took a rest half way through the 2 hour trip anyway to stretch.
if you are one of those guys that will come on and say you drive 500+kms every day and BEV is just unacceptable for you, well guess what, just get a fucking Hydrogen EV, pretty sure those can get up to 1000km ranges already which is more than my Diesel Hyundai.
Faster charging means a lower chance of all the chargers are in use at the service stations en-route. Currently if you're in need of a charge you'll have to wait for the others cars to get charged and then you still have the 20+ minute wait for your own car. That's going to put a lot of folks off owning an EV. Coupled with the fact the EV uptake is growing a lot faster than the charging infrastructure to support it. Faster charging has a lot of benefits.
except, the vast majority of your trips are from your home to some place and back, you charge at home and the range is more than enough to cover 90+% of your trips.
rather than focusing on super chargers (which we also need along high ways) we need to focus on smaller lvl 2 chargers at places where they make sense, apartment complexes, offices, to enable BEV use for people who don't own a home with their own garage.
you also completely ignore load balancing of the infrastructure, for one 350KW charger you can create 7 50KW chargers, that means 7 cars being charged while parked at places you spend lots of time at instead of 1 charger charging 1 car.
so like I said, fast chargers make sense next to main roads and highways during long trips and they don't make much sense at all in cities.
This assumes everyone can have a charger at home. A large portion of people can't. Apartments, associated spaces, on-road parking... a lot of people need public chargers.
we can build out charging infrastructure for apartments and offices
