SAN FRANCISCO -- Tesla Motors Inc. may get batteries for its energy unit from Samsung SDI Co., CEO Elon Musk said on Twitter.
After reports that Samsung batteries might supply Tesla’s electric vehicles, Musk tweeted that Panasonic, a longtime investor in the California automaker, will be the exclusive supplier of batteries to the upcoming Model 3 small car, as it is for the Model S large sedan and Model X SUV. Asked if Samsung might supply Tesla Energy, on Wednesday morning he replied “yes.”
Tesla Energy is the business unit that provides stationary batteries for homes, known as the Powerwall, and for businesses and utilities, known as the Powerpack. In the first quarter, it delivered more than 2,500 Powerwalls and almost 100 Powerpacks in North America, Asia, Europe and Africa, Tesla said last month.
Tesla and Panasonic, based in Kadoma, Japan, have a strong partnership. Panasonic invested $30 million in Tesla in 2010 -- now worth more than $300 million -- and the two companies have a supply agreement for 1.8 billion cells through 2017. Those cells are for both the Model S and the Model X.
