Tesla Battery Gossip cut n paste

As Florida residents fled Hurricane Irma over the weekend, some Tesla owners got a little surprise from the auto maker to help them get out of the danger zone.

On Saturday, Tesla began pushing a software update that increased the battery capacity of some Model S sedans and Model X SUVs. All the cars that received the update belonged to those living in what emergency officials had identified as the evacuation area.

The real-time update extended the range of the cars by unlocking previously inaccessible battery power, meaning the vehicles could now go farther on a single charge. The change will not be permanent; Tesla said the temporary upgrade will be reversed on Sept. 16, presumably once the immediate danger has passed.

The decision reflects a key distinguishing feature of Tesla's business, one that could divide consumers as they think about the future of car ownership.

The Model S and Model X vehicles updated on Saturday were all built with a 75 kilowatt-hour battery. At full capacity, that's enough for a Model S to travel roughly 250 miles.

When those cars were first sold, Tesla gave customers the option of a lower-capacity battery at a more affordable price, and some decided to take the savings rather than purchase the full, 75-kWh battery.

But downsizing didn't mean replacing the big battery with a physically smaller one; it just meant using a bit of computer code to restrict how much of the battery the car could access. If they wanted, they could later have Tesla lift the software lock by paying an additional fee, which can run into the thousands of dollars.
