Tesla Updates Powerwall Software For Easier EV Charging During A Blackout

Let’s say you have a Tesla electric car that you typically charge at home. Everything goes swimmingly until the electricity goes out. Now what? If you have a Tesla Powerwall installed at your home, you can use it to recharge your car, but at some point all the stored electricity can go into the battery of your car, leaving none left over to power your home. Not to worry, though. Elon Musk and his minions have figured out a way to let you program how much of your Powerwall’s capacity should be devoted to charging your car and how much should be reserved for domestic use, thanks to a new software upgrade to the Powerwall app. The change only applies to Model 3 and Model Y cars in North America for the moment, but Tesla plans to make it work with Model S and Model X vehicles soon and expects to expand it to other parts of the world shortly.
