IMO the simplest answer is L2 charging everywhere, DCFC on highways, both with reliable uptime and repair windows.
If one could charge at home, work, the grocery store, the bank, the mall, the theater or everywhere else they might run an errand from time to time, the chargers don’t need to be that fast or expensive, EV batteries don’t need to be as big, and L2 chargers are a fraction of the installation and upkeep cost of DCFC with minimal wear on battery life. This also means EVs could be lighter and cheaper with smaller batteries.
DCFC makes sense every 50 miles or so on freeways to more than cover anyone looking to road trip.
Ubiquity and SLA’s are the two biggest areas functionally holding back our infrastructure.
It annoys me to no end when you see a mall advertising EV charging and it’s like 2 plugs that work maybe half the year for their parking lot with like 1k spaces.
The problem isn’t range or speeds. It’s availability and reliability. That’s it. Not all chargers need to be DCFC, we just need more of them with reliable uptime
