There is only a car mafia constraint.
Initially there was a plan to change accumulators at "gas stations". But
this does not allow the manufacturer to charge you 3x more than the
accumulator's real value if you buy an expensive car. It also means
that you have a bit less design freedom.
So you will always have to wait for recharging instead of spending 2-3
minutes for a ACU change.
Or simply said: Nobody want's that the customer has real choice. Same
with Apple products or many others...

Hi,
One of the constraints placed on battery design is they should be able to
charge as fast as possible. However this
constraint is a hang over from the gasoline age. The intent is to allow fast charging at
a "gas station".
However, in future, most cars will charge using power provided by solar panels
on the roof, either at home or at work.
This will happen on a daily basis while the vehicle is not in use, so there is
no real need for a fast charging
capability for the majority of cars, which are primarily used to commute anyway.
The only thing that actually needs to change is the mentality of the car
owners, and this will happen as people get used
to the concept.
Gas stations themselves will become obsolete, and eventually be phased out
altogether.
If an electric vehicle can drive about 4 hours on a single charge, then that
should be sufficient, on long trips, as
people stop for meal breaks etc. roughly that often anyway, and the car can be
recharged during the meal.
This implies that there will be a growing market for recharging bays in the
parking lots of highway restaurants, and
those that offer this facility, will find that they increase their patronage.
Buy electric cars and recharge them from solar panels on your roof.
