Just to play devil's advocate. For a majority of people, I think most trips aren't long enough to require battery charging/swapping. Charging happens in between your trips when you don't need the car anyway. I travel regionally for work, but even on days that I spend a lot of time in the car my journey may only be 200-300 miles, punctuated by meetings and project work. This system does appear to have advantages for vehicles that are being driven continuously, like taxis, delivery vehicles, or long haul. I think the capital expense for a complicated apparatus like this might be justifiable if you can amortize it across a fleet of vehicles. One drawback may be that if this complicated equipment breaks, you are in a pickle unless you have access to another battery machine. ------ -> You know, the solution the manchild in charge of Tesla said wouldn't work. Disappointing personal opinion unnecessary to your point. ------ Edit: Another drawback may be technology lock in. If battery swap stations only service one brand of car you could look at them as having a reduced utility compared to an industry standard battery pack design. This is not an insurmountable problem, but worth consideration from an economic efficiency perspective.
