Tesla Unveils Batteries for Home and Businesses
As anticipated, Tesla Motors CEO Elon Musk unveiled a suite of batteries for homes, business and utilities at an event packed with media and Tesla owners Thursday evening at the company’s design studio at Hawthorne, Calif. airport.
In a press conference prior to the event, Musk, with typical hyperbole, said Tesla’s goal “is fundamentally to change the way the world uses energy to completely sustainable zero carbon.”
Elon Musk once negotiated a sale of Tesla to Google and shook hands on the talks, but a deal never came together in the end, according to a new book about the Tesla CEO.
The Tesla Powerwall, a rechargeable lithium-ion battery for the home derived from the battery used in Tesla’s Model S sedan, will mount on a wall and serve as a backup during power failures and to supplement power supplied by traditional utilities. The battery would allow homes equipped with solar panels to store energy and use it later.
The battery sells for $3,500 and delivers 10 kw hours of power but Musk said most will be leased to home owners and installed by third-party partners certified by Tesla.
Musk said nine of the units could be combined and would deliver 90 kw of hours, “and that’s quite a lot,” he said.
