Batteries to help power homes

by denergi admin


US electric carmaker Tesla Motors aims to move into the energy sector as it launches batteries that can power homes and businesses as it attempts to expand beyond its vehicle business. D-ENERGi director Zico Ahmed said “This is really an exciting innovation within the energy sector, the battery device would allow consumers to get off the power grid or bring energy to remote areas that are not on a grid.” Tesla plans to start shipping the units to installers in the US by this summer, and plans are underway for a launch in the UK early next year.  In a highly anticipated event near Los Angeles, Mr Musk said the move could help change the “entire energy infrastructure of the world”. “Tesla Energy is a critical step in this mission to enable zero emission power generation,” the company said in a statement. The rechargeable lithium-ion battery unit would be built using the same batteries Tesla produces for its electric vehicles, analysts said. The system is called Powerwall, and Tesla will sell the 7kWh unit for $3,000 (£1,954), while the 10kWh unit will retail for $3,500 (£2,275) to installers. Energy comparison firm USwitch estimates that one kWh can power two days of work on a laptop, a full washing machine cycle or be used to boil a kettle 10 times.
