The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle.
Official details of the project are still a ways off. When the good folks at Gizmag contacted them, Tesla said they’re currently not sharing any additional information about their energy storage and home batteries for several months. What Musk did reveal during the conference call was that “we’re going to unveil the Tesla home battery, or consumer battery, that will be for use in people’s houses or businesses, fairly soon.” Adding that, “we have the design done and it should start going into production probably in about six months or so. We’re trying to figure out a date to have the product unveiling – it’s probably in the next month or two. It’s really great. I’m really excited about it.”
As the company’s first foray into selling directly to the home energy storage market, the batteries are expected to get plenty of attention just by virtue of the attached Tesla label. And it should be an improvement from the home batteries Tesla has been quietly supplying to its sister company, the solar panel maker SolarCity, located up the road from Tesla in San Mateo, California. Those batteries are currently available in select markets within California, and only through SolarCity. The new batteries would be more widely available.
