Tesla CEO Elon Musk has promised a swappable-battery demo at a company event on June 20 event.
Rumors have been swirling for months that Musk's Tesla was working on a technology that would allow drivers with batteries running low to get out of one of its electric cars and swap the battery for one that's ostensibly full. That would allow for more driving without needing to stop and recharge.
Last month, Tesla filed a document with the Securities and Exchange Commission outlining its plans to deliver the "capability to rapidly swap out the Model S battery pack and the development of specialized public facilities to perform such swapping, which do not currently exist but which we plan to introduce in the near future." Musk didn't say anything about those facilities on his Twitter page.
