i see how the system works in refitting the batteries. but it wont be quicker than refilling at the pump because when there are say six cars already being refueled at a garage you use the next available pump and start refueling, in the case of the refitting bay you will have to wait your turn, it could take ages. and what i am saying is that its not possible to have 10 or more separate battery fitting bays built onto a garage space.
this system can only remain a niche one for a very small number of electric cars.
the technology for remote electrical charging exists, i think there needs to be a national network of charge systems fitted roadside or under the road where cars will naturally wait for short periods such as traffic lights, roundabouts etc. in towns and cities this could provide some needed capacity.
something more radical is needed for all electric cars in rural areas.
