I have called Tesla’s plan to develop a proprietary supercharging system usable only by their cars a folly. Yet Elon Musk has his reasons for doing so, and tonight he will make the case for the Tesla “supercharger” system that he says will completely fill the 85 kWh battery pack in Tesla Model S in an hour.
If that is true, that would make it the fastest charging system on the market by a wide margin. most publicly-installed Level 2 chargers take between three and six hours to charge a battery pack one-third the size. Even Level 3 chargers take an hour or more to top off a 24 kWh battery like those found in the Nissan Leaf.
From the sounds of it though, these Tesla supercharging stations will be more something more. Solar power will be utilized, though from the sounds of it not as the main source of energy. Musk says that 30 minutes of charging will provide three hours of driving. That’s not a bad tradeoff, and from the looks of the teaser image these supercharging stations may be more than just a plug in the wall.
Tesla’s plan calls for 30 supercharger stations up and down the coastal U.S. This will allow drivers of the Model S sedan with the 60 kWh and 85 kWh battery packs to travel the most densely-populated parts of the country. Those opting fort the “cheap” 40 kWh battery packs won’t be able to use the supercharging system, though future Tesla vehicles will no doubt have supercharger capacity built into them as well.
All will be revealed tonight at the official unveiling. I’ll have more details for you on the morrow.
