As promised, in late April, the company Tesla Motors unveiled Powerwall battery packs for home use. In fact, this battery of lithium-ion cells with a liquid cooling system that allows you to store energy during the day and release it in the morning and evening. Tthe battery stores energy received from the sun, allowing you to save on the electricity network in the morning and evening. For such a daily cycle Tesla Energy, a new division Tesla Motors, offers battery module capacity 7
kW · h - they cost $ 3,000 excluding the inverter and installation services. Slightly better able to withstand the load module Tesla Powerwall capacity of 10 kW · h - one unit can be assembled uninterruptible power supply of the house. Both types of modules can be combined into blocks of nine pieces that will ensure supply of electricity to 63 kW · h and 90 kW · h, respectively.
Actually, the module Tesla Powerwall has a relatively modest dimensions: 1300 x 860 x 180 mm combined with a mass of 100 kg and elegant case, which can be not only white. This module is mounted on a wall in the garage or on the facade of the house. However, outside seating imposes some restrictions: the module is designed for a temperature range from minus 20 to plus 43 degrees Celsius. Here is the unit of two modules Tesla Powerwall:
Each module is capable of providing up to 2 kW load, the steady operation, and to 3.3 kW peak mode. Accordingly, the current changes from 5.8 A to 8.6 A. The voltage ranges from 350 to 450 V.
Where climatic conditions are not conducive to the active use of solar cells, modules Tesla Power can be used to charge accumulation at night when electricity is cheaper, with its subsequent consumption during periods of higher tariff. Business users Tesla Energy addresses the Powerpack battery modules capacity of 100 kW · h, which will cost between $ 25,000 and scaled nearly indefinitely. Anyway, one of the customers are already expects to receive from the Tesla Energy "battery plant"
with capacity of 250 megawatts. It is expected that the installation of residential units Powerwall will deal with energy companies and specialized services, but maintaining brand ten years warranty Tesla. The first customers will receive the battery this summer. Related Products :
