Tesla webcasting Supercharger quick-charge unveiling tonight

Tesla will announce its new Model S Supercharger in a webcast tonight

It all began with a late-night tweet two weeks ago by Tesla Motors CEO Elon Musk.

In it, he announced that Tesla would unveil its much-discussed Supercharger network of dedicated quick-charging stations — only usable to 2012 Tesla Model S drivers — on September 24.

Well, today’s the day. And this evening, the world can watch to learn details of a device that, Musk says, “will feel like alien spaceships landed at highway rest stops.”

OK, then.

Tesla Motors [NSDQ:TSLA] plans to reveal not only the looks and details of the Supercharger but also its deployment plans in a webcast tonight from an event that starts at 7:30 Pacific (10:30 p.m. Eastern).

Starting at 8 p.m. Pacific (11 p.m. Eastern), you can watch a webcast of the Supercharger event online.

Tesla calls tonight’s event, to be held at the company’s Design Studio in Hawthorne, Calif., not an unveiling or a launch but a “Premiere.”

The announcement, we note, appears to have caught Tesla’s communications staff slightly off guard. Rumor has it they first learned of today’s date via Musk’s tweet.

The need for quick charging has to do with the large lithium-ion battery packs of the Model S variants. The 85-kilowatt-hour pack would take 12 hours or more to recharge fully using a conventional 240-Volt, Level 2 charging station.

Thus far, here’s what we know about the Supercharger:

For more beyond that, tune in to tonight’s event.

If past events, including the first public showing of the Model S prototype and the unveiling of the Model X crossover concept early this year, are any indication, the event will follow a set format.

It will have questionable lighting for photography, hordes of fans and reporters crowded into roped-off areas, and a lot of tired-looking Tesla employees applauding enthusiastically.

We’ll provide a rundown of the details and the event later in the week.
