I have no doubt the charging tech is good now and will be great, but I have less doubt about the masses being impatient.
.
The time it takes (or will take) to charge a car is perfectly acceptable in a vacuum, but when people are used to filling up their car with gas in 3 minutes, then a half hour to charge it becomes a problem.
Well, there are other issues.
I contend that for anyone with the capability of charging at home, there's no issue at all.
The problem is that the US home ownership rate is only 65%. That leaves 35% of the population without the ability to install a home charger. That includes me, for example. I could certainly go BEV and I even have a garage, but my
slumlord landlord isn't going to put a Level 2 charger in his rental property. So even if I was in the BEV market right now, I wouldn't do it until I own my own home.
That 65% also probably includes folks like CD who live in posh condo towers... While his tower probably already has EV charging, people who own condos or townhomes that fit into that 65% may be in situations where they don't have secure garages, and only have carports. Not to mention that portions of that 65% who are in single family homes don't have garages at all, and only have street parking.
Right now a BEV is a luxury good and primarily owned by people who have the capability to charge at home... In order to go "down market" the home charging infrastructure will need to mature.
Still, I view all of this as more likely than battery swaps, especially since the charging infrastructure will grow slowly over time incrementally with the growth of BEV, so it's not a "chicken & egg" problem.
