The pilot project would be an initial demonstration of how the system will work when it is in full swing, where it has been specially designed to test the technical aspects of the procedure, and to check out whether Tesla drivers would prefer to recharge the Model S’ current battery pack, since the swap will cost “slightly less than a full tank of gasoline for a premium sedan”, according to Tesla. Of course, who are we to say that this will not change down the road, but the swap will include labor and facility costs which charging does not.
Apart from that, one would need to set an appointment in advance, and the swapping process right now takes three minutes to complete, with Tesla looking to reduce that time to just a minute. I wonder what happens if the swapped battery runs into issues halfway – will there be a free emergency towing service by Tesla?
