Price intelligent battery Tesla the best Bashny.Net

At the end of April, the company introduced the Tesla battery for the home. What it is: the next revolution from the American Corporation or a logical link on the path to building intelligent and independent at home? Let's get together. Elon musk is rightfully can be called revolutionary in the world of technology. 10 years ago few people believed that electric cars will hit the market, and today the Tesla Model S sedan, which was not averse to take possession of every car enthusiast.



Alternative to a petrol engine was found long ago, but that "to break an entire industry" for a long time no one dared. The issue of production and consumption in the twenty-first century is particularly acute. Today it literally affects the existence of mankind. The traditional classification of energy production has two major branches: extraction using commercial sources: coal, oil shale, oil, gas (in fact, they are the basis of modern energy, covering 90% of the total requests from the enterprises and population), nuclear, hydro, geothermal, solar, wave and tidal station.

production from the use of non-commercial sources: industrial and agricultural wastes muscular energy, firewood.





Despite the crisis fuel resources, which was full of headlines of Newspapers in the early 70-ies, after almost 50 years in the principles of production of electricity, little has changed. The population is growing, increasing the potential need for electricity, and as a consequence, more and more polluting the planet. And you can argue about what comes first – the energy crisis or environmental disaster, but the best way out of this situation is to radically overhaul energy industry and the principles of supply of electricity.

Energy and infrastructure Tesla





April 30, Elon Musk presents the solution, which should reflect positively not only on the environment but also on the wallets of consumers. Tesla Powerwall cares about the environment, dramatically reducing the carbon footprint and allows you to forget about the impressive energy bills. On the last point we will deal with later, but for now look at the world, which offers us the Tesla. The idea of energy storage and Autonomous software houses – not new. Many owners of country houses were covered with roofs of their homes with solar panels, providing power using lead-acid batteries.

And here is the first advantage of Tesla Powerwall. Battery. Power source is the brainchild of Tesla is Li-ion rechargeable battery, its characteristics are far superior to the archaic lead acid, developed in 1859.

Number of cycles of charge-discharge lead-acid battery barely reaches 800, while Li-ion can boast of 1000-1200 cycles. The ratio of "weight-capacity" lithium-ion battery is almost 5 times greater than lead-acid. This is what allowed Tesla to create a catchy design of its new line of products.

Design and form factor





Yes, the opinion about any product the person develops from its appearance. Rounded edges, minimal thickness (according to standards of competing products), the availability of a range of colors. Even without delving into the principles of Tesla Powerwall, start to think about how it complements your garage. Tesla Powerwall mounted on the wall and occupies a minimum of space.

A whole ecosystem

Presents Tesla Powerwall come in two versions with a capacity of 7 and 10 kWh at a price of $3000 and $3500 respectively. If the consumer experiences a distinct lack of capacity, it can always complement the Arsenal of batteries with purchase of another, thereby increasing the total capacity up to 90 kW*h (allowed to connect up to 9 panels). The connection does not require a thorough study of principles of construction electricity: single cable solves all the problems.

Enterprise solution and business





Together with the Powerwall was presented and a product that can solve the problem of providing factories, plants and a whole industry – the Tesla Powerpack. Their feature – the ability of an infinite increase of potential capacity up to several GW*h.

Plans for full electrification alternative

Elon Musk – a man who is used to thinking globally. That is why the presentation of batteries, the Tesla has one goal for the implementation of the product to a limited number of interested users. We are talking about a massive and total electrification of the entire planet Earth with the help of batteries. To provide the entire planet with energy 900 million of Tesla enough battery Powerpack. Concern about the environment, not the production of electricity, the source of which will serve as exhaustible natural resources leading to the emission of harmful substances into the atmosphere and the absolute independence of any, even the most remote corner of the planet – all this is the reality already today. But until that moment comes (if comes at all) the global transition to electricity derive from solar, wind, tidal and stored in the batteries, a potential buyer interested in the question: is it profitable acquisition of Tesla Powerwall today?

Dry figures





So, let's calculate the economic feasibility of purchasing an innovative product from Tesla. Is it worth "powder and shot" and how will payback in terms of Russia and the United States.

The conditions of calculations:

• take daily consumption of electricity by the owner of Tesla Powerwall equal to 10 kW, i.e. total capacity of battery consumption per day;
• the cost of the Tesla Powerwall — $3 500, at the rate current at the time of publication of these calculations is 175 000 rubles (with account of rounding at the rate of repossessed a 50.01 rubles per $1);
• to the cost of the Tesla Powerwall add the need to oversize the inverter, which costs about $1500 to 75 000 rubles;
• consider the losses when connecting Tesla Powerwall in the chain battery – inverter DC – inverter. Overall system efficiency will be 87%. I.e. initially the consumer is not available 10 kWh, but only for 8.7.
• with dual-zone tariffing (tariff "day/night") will take the daily energy consumption at 5 kW*h (57,5% of the maximum resource Tesla Powerwall), and evening – at the level of 3.7 kW*h (42.5 per cent).

The situation in the US

In the U.S. operates a two-band tariff for electricity:

From 14:00 to 19:00 the cost of 1 kWh of electricity is $0,2032 (10,16 rubles).

From 19:00 to 14:00 price plummets to $0,0463 (2,31 rubles) per 1 kWh.

The consumption of 5 kW*h per day and 3.7 kWh in the "night" time daily expenses if you use the standard mains will be: 5kW*h * 10,16 RUB + 3,7 kWh * 2,31 RUB = RUB 50,82 + 8,54 RUB = 59,36 rubles/day. Of 59.34 rubles * 365 days = 21 659 rubles per year. Standard lithium-ion battery loses about 6% (0.6 kW) of its original capacity (ie 10 kW) per year. Every year its capacity will be reduced after only 3-4 years only one Tesla Powerwall will not be enough. Here is a sample calculation of how to behave in the battery over time.

Years of operation: maximum battery life is 15 years.

Maximum capacity: reduced by 6% (0.6 kW) of the initial capacity every year.

The cost of electricity: calculated from the ratio of day/night tariff for the above prices.

Savings: what amount allows you to save Tesla Powerwall per year.

Waste on extra energy: we have agreed that the daily consumption of 8.7 kW. The remaining electricity (caused by degradation of the battery) will compensate the grid for shared use. Over 15 years of use, even without considering costs for additional energy, Tesla Powerwall doesn't pay. If you consider that the cost of a kilowatt hour of electricity in Russia is below about 60%, to talk about the feasibility of such an acquisition is unlikely. Let me remind you that buying a kit Tesla Powerwall cost of 250 000 and that is excluding the solar panels.

Reflections





Proposed by Tesla a non – volatile solution is the correct view of the future emissions and merciless use of natural resources. Alas, for the end consumer stated on the Tesla Powerwall cost will not be cost-effective acquisition.

To purchase the battery will need to add "price incense and candles" in the form of solar panels, Converter and inverter, and degradation of lithium-ion batteries simply will not allow you to cover the upfront costs. But if you are willing to invest in the future, ready to make the step towards "green planet" and the issue price is not decisive – Tesla Powerwall time for you has come. And don't forget that the disposal of any battery also costs money. Sometimes a lot. published

P. S. And remember, only by changing their consumption — together we change the world! ©
