Battery tech really does move fast
Battery tech really does move fast
Just two years ago my car's 50 kWh battery weighed around 350 kg, now you can get a 45 kWh battery that fits in the palm of your hand!
You're viewing a single thread.
Could this power my home for 8 to 10 years?
It's impossible to say, but if we assume it's a typical Li-ion battery supplying 3.7V, then:
9 kAh x 3.7 V = 33.3 kWh
So, it would be enough to power the average American house (10 MWh/year) for 1.2 days, or 4 days for a typical European flat (3 MWh/year).
Edited wrong yearly consumption
I think your math is off given that just a typical US consumer full sized refrigerator can use ~650 kWh/year and still be considered Energy Star qualified.
What, my house used 78 kWh yesterday.
Have you tried not mining bitcoins?
Yes but I haven't tried not living in the arctic..
you should get some asics and mergemine while you heat your home
You are off by a factor 1000 on the household power consumption (I think these numbers are without heating or assumes that you don't have electrical heating?). And the voltage could be anything on a magical battery ;)
Whoops, you're right the values for yearly cosumption should be x1000, or in MWh. So, it's just enough for a day or two.
That fits with people's stories of running their homes from their car battery for ~3 days during power outs.
