No, indeed not, which is obviously going to limit the appeal of electric
vehicles :-) Though Tesla have fast charging stations which can give 50%
charge is about 20 mins.

Or 40 minutes for an full charge?

No - 75 mins according to Tesla - the last 20% is proportionately longer.

Excessive heat during charging may be the killer of batteries hence long
charge times. Fast (???) charge stations may be more convenient but at a
cost of a shorter battery life.

When the take up of electric cars becomes significant I wonder how long
it will then take for every computer route to be grid locked every day
due to drivers getting the last mile out of the old battery. Do you
remember when milk was delivered every day to the doorstep by a electric
milk float and at the end of the round the local traffic queue was a
result of following a vehicle with insufficient performance to climb a
sleeping policeman?


I suspect the control computer will just refuse to start the car after
n-months of warnings once the battery is that dead.
