So owners will need two cars - one on charge & one on the road. Oh for a
time machine!

Batteries are extremely heavy and have to be built into the car’s architecture.
Swapping them out would be very difficult. They will become more compact, but
that will be a slow process, and thy’ll probably never weight less than a few
hundred pounds. (That’s why, in the days of lesser batteries, Formula E elected
to swap out complete cars rather than batteries.) There have been exponential
improvements in charging rates, and I expect that to continue. Plus, as DC fast
charging stations proliferate on major routs, topping off occasionally will
make sense. Motorists won’t be charging from point zero but rather adding 100
or 200 miles range at a time. That being said, IC engine vehicles and plug-in
hybrids will remain the choice for long trip driving for many years to come.
Electrics, though, are great urban cars, as one can top off the battery daily
at home, as my article explained and as the industry experts point out.

Thanks Rick. I enjoyed driving the Bolt for a week
While I was working on the charging piece. I think well eventually see cars
with 400 mile range and much faster charging.
I think what the electric car industry needs to do is adopt the
"propane" business model: You don't generally get your propane tank
refilled, you exchange it for a filled one. Someday you should be able
to pull into a service station in your electric car and have your
almost-depleted battery exchanged for a fully charged one (batteries
would have to log the number of charge/discharge cycles they've been
through in order to vary the credit you get for the one you're
exchanging). This would of course require standardization of car
batteries and creation of a quick remove/replace architecture. A lot
of standardization and infrastructure hurdles to clear, to be sure,
but I don't see battery charging rates approaching the time it takes
to fill a 10-gallon gasoline tank any time soon.
