Tesla has upped the stakes with their announcement of battery swapping robots. The idea is simple, everyone understands how to fill ones car with gas. Now, the concept is applied to electric cars. Just swap out the dead battery for a fully charged one. According to Tesla it will cost about the same as a tank of gas. I’m not sure at that price point that it will make them any money but it probably will cover their R&D costs. Their characterization of the cost also makes me wonder whether the price will fluctuate like a a tank of gas does… Some of the obvious questions will need to be answered. My list is as follows: Will the swapped battery be as good (cycles, capacity, etc) as the original? Will it be covered under the warranty in the same way the original one would? Or, will it be a bit like what happens when you refill your BBQ propane tanks, your tank is new and shiny but the one that comes back after the swap looks like it has been through a war. These are the issues that must be figured out before a massive roll out of these swapping robots. If I know Tesla they will do it right. Tesla has some of the answers already, but I’m sure as this rolls out into the wild, more will arise. In either case I applaud Tesla for their ingenuity and resolve to change the way we drive.
