tesla's home battery pack that could 'change the way the world uses energy': elon musk unveils $3,000 device that can power an entire home for eight hours - battery energy storage system

Tesla founder Elon Musk unveiled a $3,000 "revolution"£1,980)
He claimed the battery could run the whole family for eight hours.
Musk introduced the Powerwall device at a press conference in California last night and said the technology could "change the world ".
The device may be at home at the end of the summer, and when it's cheaper, it can store electricity at night.
Scroll down to watch the video, and then it will drain a lot of this cheap power during the day, which is enough to be useful for homes and businesses.
Powerwall is about 3 feet wide, 4 feet high and heavy and can be installed on the exterior or inner walls of the home.
The capacity of the "daily use" version is 7 KW
Hours, about a quarter of the daily use of the family.
According to the Department of EnergyS.
Household 10,908 KW-
There is a few hours of energy each year, or only 30 hours a day.
According to this number, a complete
Charging Powerwall devices will be able to meet the energy needs of the home on any day.
However, when the household uses the vast majority of electricity, it may last less than 8 hours in the morning and at night.
The devices can be stacked together to provide more energy, Musk said.
The system will make it easy for homeowners with solar panels or other renewable energy sources to store their energy at home rather than the current model, that is, they sell electricity to energy suppliers when generating electricity, then buy again during peak hours.
It can also allow savvy consumers to take advantage of lower rates for power companies at night and use cheaper storage energy during peak hours.
According to Mashable, a technology website, Musk told attendees: "Our goal is to fundamentally change the way the world uses energy.
"It sounds crazy, but we want to turn the global energy infrastructure into zero carbon.
And every day-
Tesla will also launch a 10 KW-
The hourly battery is designed to help families tide over during power outages, such as during power outages caused by storms.
Marketing materials for the device, released late Thursday on Tesla's website, said: "powerwall is a household battery that uses power generated by solar panels to charge, or power your home at night when utility rates
It also strengthens your home from power outages by providing backup power supplies.
Powerwall is automated, compact and simple to install, providing the security of independence and emergency backup with the utility grid.
Musk said he wants to sell hundreds of millions of such equipment, which he believes has improved a lot than it currently has --
Available models.
In the past, he had said that this early battery was rotten.
He later added that the entire display cabinet was powered by a large number of Powerwall batteries.
Tesla also launched the "powerpack", a larger version of Powerwall.
It describes it as an "unlimited extension system" that can work for businesses, industrial applications, and utilities ".
It has a battery block of 100 degrees and can be extended from 500 degrees to 10 MW.
The report says our goal is to change the way the world uses energy on an extreme scale.
The latest announcement was based on Tesla's previous product, mainly its range of cars.
Last year, Tesla Motors unveiled a "Gigabit battery" program designed to help the company boost production of electric cars and now home batteries.
Tesla said the plant would cut the current cost of battery production by as much as it could, and would be powered mainly by renewable sources such as wind and solar.
Elsewhere, Musk is already the chairman of SolarCity.
A company that provides solar systems for families --
Tesla's home battery may be an extension of this.
These batteries are 3ft high (0. 9 metres)
And can be controlled remotely using the smartphone app.
Tesla will not comment on whether the new battery will work the same way.
Household battery packs can disrupt the utility market.

The state-owned power company issued a report on power outages.
It is conceivable that one day battery storage technology or micro-turbines will allow customers to be independent of the grid, the report said.
Deutsche Bank estimates that sales of fixed-cell storage systems for home and commercial use could be as high as $4.
Tesla's revenue is 5 billion.
Analysts expect Tesla to build fixed storage systems around the basic batteries it produces for its vehicles at a large plant in Nevada.
A fixed storage system may be part of a fossil.
A fuel-free lifestyle in which a person has solar panels on his roof, power generation can power household appliances and give batteries in a Tesla Model S sedan parked in a garage
Government subsidies and a sharp drop in the price of lithium-ion batteries have attracted more companies to enter the home storage business.
Tesla has received $1 so far.
Self-100 from California
A Generation Incentive Program.
According to the state, Tesla has or is prepared to receive state funding for about 600 storage projects in California.
According to research firm ihs cera, although the valuation in 2012 was only $0. 2 billion, the energy storage industry is expected to grow to $19 billion by 2017.
