article imageTesla gets into the battery business with Powerwall, Powerpack

By Michael Thomas     May 1, 2015 in Technology
Tesla, best known for its electric car sales, is heading into the energy business with its Internet-connected Powerwall and Powerpack batteries.
Tesla CEO Elon Musk unveiled the new batteries Thursday night as he described the company's new product line, Tesla Energy. Musk hopes these new power sources will revolutionize the way the public thinks about energy.
Tesla Energy will release two products, available later this year. The Powerwall battery is intended for use in the home, while the Powerpack is aimed at businesses of all sizes.
The Powerwall comes in two voltage capacities — 10 kWh and 7 kWh for $3,500 and $3,000, respectively. The battery is three feet by four feet and six inches thick, and manages any kind of heat, allowing it to be attached to the inside or outside of the home. The battery also connects to the Internet, allowing users to reduce redundant lighting and even take their entire home off the power grid. Gizmodo provides more detailed stats, saying the battery operates at >92 percent round trip efficiency and can work in temperatures ranging from -20C (-4F) to 43C (110F).
The batteries also come in a slew of different colours.
The Powerpack comes in 100 kWh blocks that can scale all the way up to 10 MWh, which ideally makes them suitable for businesses of all sizes, and even utility companies.
The idea behind the batteries, according to Musk, is reduce the world's dependency on "the grid," Solar power is a popular alternative energy source, but will obviously be of no use to someone when the sun isn't available. The Tesla Energy products ideally will help fix that problem and stabilize infrastructure with fewer homes drawing on the grid.
Though the Powerwall and Powerpack have just been officially announced, Tesla has been testing the batteries for about a year, and has sold them to a few consumers. The Powerwall is expected to ship this summer, with the first few Powerpacks coming "later this year" and then becoming fully available in 2016.
