I'm not sure EV charging stations will ever be as prolific as gas
stations are now.
The 300 million cars are served by about 120,000 gas stations in the USA...
What about when we get to 300M EVs? Lets assume 80% charge at home
leaving 60M needing public charging... 250,000 high speed chargers needed.
Which is just two per gas station. Certainly possible.
That leaves the 9 million needing 3 hours a day at L2 for 36 million L2
charging hours a day. Divided by 24 gives about 1,500,000 public L2
chargers.
Roughly 12 times the number of gas stations. But L2 chargers can be put
almost anywhere; any business can have one. So it is quite conceivable
to have that many.
So I say as I have always said... "anyone who buys an EV with the idea of
dependence on public charging will be VERY disappointed!
Right now, yes! To my mind, it is GOOD not to depend on public charging.
Charge at home!
But as an engineer, I see no technological challenges with a system
where home charging is somehow prevented, so that paid public charging
is the only option. The oil companies could convert their gas stations
to "filling stations" with EV fast chargers. The power companies could
get into the public charging business, and license smaller L2 chargers
the same way banks set up ATMs in every mall and big-box store. There
are easily 12 times more places where such EVSE's could be put than just
at gas stations. Any public place you park your car could have one.
Cities, states, stores, the oil companies, power companies, and whoever
makes these EVSE's would all see it as a new source of profits. All of
them would lobby for such a solution.
They get complete control over the price and delivery. They can tax the
bejesus out of the electricity, just like fuel taxes. They can limit or
shut down the chargers in case of brownouts, or even "borrow" power from
your EV battery packs when needed.
THAT's my worry.
