What I mean is that all cars would use the same base battery system (maybe several tiers of capacity).
Your cars have IDs built in and it communicates with the station when you pull up.
Like a carwash - you roll up, technology logs your car - in you go - out the other end with the charged battery. Every car uses them - you get billed for each “fill” and how much was left on the old one.
Like epass on tollways - people use them and get billed accordingly. Everything gets worked out without anyone leaving their car.
I get it. To fill my pickup at the service station is about 4 minutes all said and done, of course I get around 525 miles with my extended 32 gallon tank, so I can head to Fargo, and make it back to Bismarck sometimes before needing to fill again.
So if these electric battery places can swap out a battery every 100 miles, likely 50 in cold weather, and each battery swap out takes lets say on the light side of 18 minutes, at trip to Fargo and back would only take 12 stops at 18 minutes a stop, it would only add 3hours and 40 minutes to your journey.
Much better than the potential 2 extra days it might take you to charge that vehicle on this same journey now.
I am in.
