Got a chance to attend the swap demo in Hawthorne tonight. Other posts will cover in much more depth.
I did have a chance to have a 10 minute conversation with JB Straubel and got to ask him several questions that have been nagging at me:
1. When will Tesla owners be able to use their own battery pack at home in the same manner that Tesla is using battery backup at Superchargers, including time-of-use (TOU) and grid buffering?
JB pointed me to the Solar City battery backup that Tesla Motors designed and sells through solar city. 10kWh and very expensive. He stated that regulatory and engineering problems prevent owners from having the option of using the car battery for that purpose. He did NOT seem inclined that this would be happening in the future, although I tried to drag it out of him.
2. What is the status of the metal-air patents/range pack in the frunk?
"Some patents don't end up in the working product. However, the tesla cell chemistry is improving and a 4-500 mile pack is not that far away."
3. Is the jump from 90 kwh to 120 kwh charging the last speed increase?
No. The charging speed will be increasing.
4. How do Tesla's 18650 lithium ion cells differ from the off-the-shelf versions?
Tesla is using the 18650 "form factor" but the chemistry and several of the components are designed by Tesla and nobody else has anything as advanced. A regular laptop battery placed into the Model S would short/burn up/fail immediately.
Hope this helps clear the air with some of the wilder speculation. Although . . . things can change.
