It is a shame that manufacturers can't get it together and use one standard physical size battery that can be easily exchanged.
Drive your electric car into an exchange station, put it on the ramp like in an MOT centre, a forklift type device lifts out the old battery and pops in a recharged one and off you go. The whole thing shouldn't be much longer than a petrol fill up, particularly if you didn't do any shopping, coffee buying etc.
Your old battery would then be recharged, maybe at night, for someone else to use.
