Tesla told me that the 3.0 Battery Upgrade is not Supercharging or CHAdeMO capable. What's the point? Here is my response: When is Tesla going to have a battery upgrade that is Supercharging or CHAdeMO capable? I hope Tesla realizes this pretty much tethers Roadster users to their homes. This completely goes against Tesla’s vision for the future since all chargers do not even support Roadsters then. This is Tesla’s coming out vehicle and made Tesla what they are today. Elon Musk said how the Roadster would be the future, but Tesla has constrained it to 3 year dinosaur. I am very disappointed. Is Tesla going to come out with a Supercharing or CHAdeMO capable battery in the future? This would be very easy, because all you would need are bigger gauge wires between the battery and the charging port. Tesla response to my response: Thank you for your reply. Unfortunately we do not have any additional information regarding the future capabilities of the Roadster. We have notated your feedback and we hope to be able to offer you more improvements with the Roadster in the future.
