Tesla Announces Home Batteries

Very interesting. But I wonder how they will use lithium for this rather than traditional lead acid. They have to really change how the batteries are maintained to make this work.
Pretty much a given. I think part of the reason they do not want to use Lead Acid - wet or gel type -is the off gassing,.. it can be vented. And really - how much more dangerous is that gas over propane or natural gas....both go boom.
Even with the newer plates and matrix format, there is only so much power density in lead acid batteries. There is more in lithium - at least as I understand. I'm not a specialist. And they there is the amperage draw / life cycle issues.
-
The difference is that lead acid are designed to be kept fully charged at all times. Lithium need a charge - deplete cycle constantly to stay healthy. If you deplete regularly to keep the batteries healthy, what if you lose power during that cycle? It makes for a challenge that is very different from what they have faced in doing car batteries which charge - deplete anyway.

I am super excited about this. My current plan is to retire early and build a Tiny house. THen just drag it across the US, where ever I want to live. This kind of technology would be perfect for it. Just counting down the years at this point.

I'll probably get one of these when I put in solar panels. Saves you from having an inverter to send back to the grid. Then you can just use the grid for emergencies.

HOw does this make dragging a house easier?

It is one of those things that is promising, but I don't know if its time has come yet. Based on the kWh capacity it doesn't seem practical as yet to be completely off the grid for an average household. I do like what Tesla is doing though by pushing the boundaries of what companies are willing to try.

I guess this will be good for other area's. The US govt seems pretty against being "off the grid." because law states you have to be connected to it or be condemned in most places. Recently many amish which had been grandfather under religious exemptions have been evicted and put in jail for it. and people using only solar/wind energy being forced on the grid.
10KW will run most things. Very few people will need more than that. I only have a 100A single phase feed here But, I really don't use much of that.

@scottalanmiller Well it would be a tiny off grid house. So I would be able to put a small solar panel on the roof, and be able to run lighting and cooking needs from the Tesla battery all day and night. Currently must people just use propane, but I would rather run electric only. I'm sure in 20 years when this goal could actully happen, the technology will be amazing.

I see. It's the solar that really makes the difference

The prices will drop and the capacity will go up. Probably gen2 will be twice the capacity at half the price.

Well when this is the size of house I want to live in, I am betting I could run quite a while on a 10KW battery.
-
Does someone make those? That looks pretty neat.
-
@s.hackleman Where do you live? many places keep making those "Tiny" house illegal. both with standards that would make them illegal and minimum square footage requirements.

My cousin is looking into a house like that. Looks exactly that size, maybe a bit smaller.

It's a big movement that start a few years ago. Quickly being showdown by laws though. https://www.youtube.com/watch?v=yGomaVCVYfM

I am in Missouri, however that is why they build them on wheels. They Qualify as RV's and do not fall under the minimum squarefootage laws.

Not cheap, I can buy a "real" house for less than that!

Yep. here I can get a 1,500 SQ house here for that if you score the right deal.

Seems like a very US-consumerist "go buy one" approach to what's normally just called "living in the rest of the world."
If you want to live in a nice, tiny place like that, Europe is loaded with them.
