Powerful 6.8 kWh portable battery for backup power supply at home, construction or outdoor recreation
Almost everyone who has a summer cottage or a country house has faced a power outage. Sometimes the disconnection lasts long enough. Due to power failures or due to planned works.
If you can still supply lead batteries to power the boiler, which will last for these few hours, then a gas generator or solar batteries (with the same batteries) are needed to power electrical appliances in the house. The latter work mainly only in summer.
Why not assemble a powerful power bank on capacious Li-Ion or Li-Po cells for such a backup power supply? Unlike lead-acid batteries, they carry up to 3000 discharge-charge cycles and have a high energy storage density per 1 kg of weight.
Back in 2015 Ilona Musk promised the release of Powerwall drives for power supply at home.
They may be in the US, but you don't hear them being sold around the world as their Tesla cars.
It turns out that in Russia one company has outstripped I. Mask in these developments. And it offers two standard sizes of a powerful and also portable power bank (AKB) for backup power supply at home.
These are portable charging stations for charging electric vehicles from the Simargl-electro company. They were originally designed to recharge e-bikes, motorcycles or e-quads for outdoor trips (which they sell). But then, we realized that the purpose of this charging station could be much wider.
Back-up power supply in the house, power supply of the outlet, recharging for electric bike rental, travel, for trips to nature. Well, and powering the tool during construction where there is no central power supply.
More model characteristics: weight 48 kg, capacity 6.8 kWh. Rated power - before4.5 kW. Peak power 9 kW. 2-3 thous. charging cycles or approximately 10 years of service. Size: 550x270x500 mm. Battery in a suitcase on wheels with a telescopic handle. Those. if consumption is in denominations 1 kWthen this portable battery will be able to supply the load up to 7 o'clock.
This is a small power bank suitcase. Battery capacity: 1920W * h, rated power: 1300W (220V).
An interesting solution would be to combine these batteries with solar panels for at least 1 kW of power (at remote recreation centers). During daylight hours, the power bank will charge, and at night you can turn on the lighting and power the electrical appliances in the houses. There is no need to start a noisy gasoline generator and import fuel for it.
For builders who build without a central power supply, this is also a great option. There would also be a price comparable to the price of a gas generator.
But, unfortunately, the price is upsetting. The 6.8 kWh model costs 260 thous. rub. At 1.9 kWh - 117 thous. rub. An unaffordable price for the average consumer. Probably, these joint stock banks will be of interest to owners of real estate worth tens of millions of rubles. Or for overseas buyers. I think in the USA, in Texas, these powerful power banks would have sold out like hot cakes by winter. They remember the long power outages at the end of the winter of 2021. Where is the guarantee that this will not happen again.
Well, or for the owners of recreation centers remote from civilization, it is also an excellent option. For what price you would buy such a mobile battery - write in the comments!
