tesla unveils batteries to power homes - lithium ion rechargeable battery
Tesla Motors, an American electric vehicle maker, has launched batteries that power homes and businesses.
Chief executive Elon Musk has announced that the company will produce batteries that store solar energy.
Provide systems for consumers during power outages.
The device will allow consumers to get out of the grid or bring energy to remote areas that are not on the grid.
Tesla plans to start shipping the devices to American installers this summer.
Musk said at a much-anticipated event near Los Angeles that the move could help change "the world's energy infrastructure ".
"Tesla Energy is a key step in achieving zero-emission power generation," the company said in a statement . ".
Rechargeable lithium
Analysts say the ion battery unit will be built using the same batteries Tesla produces for its electric vehicles.
The system is called Powerwall, and Tesla will sell 7kWh for $3,000 (£1,954)
The unit will Retail $10 KW at 3,500 (£2,275)to installers.
USwitch, an energy comparison company, estimates that a laptop, a full washing machine cycle, or 10 times used to cook a kettle can power two days of work every kilowatt hour.
Musk said the company will work with SolarCity to install home batteries, but more will be announced.
Musk is the chairman and largest shareholder of SolarCity.
Tesla into so-
The market, known as "fixed storage", has huge growth potential: as the world slowly moves away from fossil fuels, it is believed that this is critical to the wider adoption of "clean" energy sources such as solar and wind.
Elon Musk uses Tesla's expertise to build Heights-
Efficient car batteries, placed in a unit of consumer housing.
The business strategy is a bit like the battery itself: the impact is great, but the release is slow, and it will only bring significant benefits over time.
But it is also accompanied by risk.
Tesla may face challenges in getting costs
Save information for potential customers, especially up to $3,500 in upfront costs.
The automaker also faces competition for batteries.
Competitors in storage technology, such as General Electric (
General Electric)
And LG Chemical, South Korea's largest chemical company.
This particular lithium-ion battery is also likely to be replaced by other technologies in a few years, such as hydrogen fuel cells that Tesla does not manufacture.
Still, Tesla is clearly prepared to take these risks.
Its cars have been well received, but sales outside the central California strip are rare.
A Geely car worth 5bn will not open until 2017. Today, only one Tesla car can be bought. diversifying its product line into such a field will be the key to making investors happy.
Sales revenue for home and enterprise battery storage systems can be as high as $4.
According to Deutsche Bank, Tesla's revenue is 5bn.
The automaker reported lower-than-market expectations for fourth-quarter earnings, losing $107 in February.
6 m production and delivery issues.
Friends of Earth's renewable energy activists say solar panels and household batteries may be as common in the future as central heating.
"Just as the Internet has changed the way we use information, renewable energy like wind and solar is changing the way we produce and use energy --
"Electricity storage is an important part of this change," he said . ".
"Cheaper and more efficient energy storage means that individuals and businesses can save energy before they need renewable energy, greatly reducing the need for climate --
Changing fossil fuels
"Colin Brown, engineering director of the Association of Mechanical Engineers, said Tesla's statement was timely to consider the government's emission reduction.
"Without storage, you always have to have huge capacity in case a certain peak comes up at a specific time --
It's a very hot day when you need a lot of cooling, so there's a lot of demand.
"With storage, you don't have to have energy production on such a large scale," he said . ".
