BIG battery comments

[Greynomad]

Thanks, T1.
Your last paragraph gives some hope — I think.
You never know… you might finally convince me that EVs are a viable alternative. If I live long enough.
Meantime, here’s food for thought.
Or maybe just a snack.

The production of lithium manganese cobalt and nickel manganese cobalt batteries use an incredible amount of water as well to refine those rare earth materials, lithium ferrous phosphate using the new concentrate extraction method uses 90% less water and can actually recycle the water it uses, the iron is a common material and the rest is a just a chemical conversion process .... so, a lot less material intense .....

Sodium ion cells/batteries use very common and abundant materials, the method of manufacture is the tricky part, but still far less energy intense.

Like the silicon used to make solar panels, uses an enormous amount of electricity to purify the silicon from common quartz, but the end produce generates 10 time the amount of power required to produce it during its life cycle.

They are now recycling the LMC and NMC cells/batteries as well as the LFP cells/batteries and recovering roughly 90% of the material used, a lot better than lead acid battery recycling as most of the lead is garbage by the end of the batteries life.

The 2,000 ltrs of diesel used by the Cat 994 per 24 hrs can never be recycled

Hey Robert Not Bob did your solar / battery man turn up & give you a quote?
I'd be interested in what was quoted.
I've got several chasing me for a final decision.
Best one I got was for an ESS something or other battery. Quoted $10.000 installed but when I got the 10th call from him I told him I was 'sitting' on the idea & he offered another 1,500 off the price!

Thats a hell of a discount, for just waiting a while. Hold on a bit longer, I think the Govt support package drops off soon.

It will be interesting. Just returned from looking at a house with a big workshop in the Barossa council area, certainly not cheap, but a very nice place all the same.

Waiting for Dottie and George to get back to us on a price for their place .... but Margaret is itching to put a bid in on this place ..... but it has no solar or battery at all, so, maybe a big system and take on the Energy trading scheme to sell energy when the price is right, otherwise, keep it for our own use.
With 170kwh hrs of additional storage in the 3 MG4s, added onto what ever battery solar package we went with, would give us a decent volume to sell.

After talking to an AEVA member at the Birdwood rally and him showing me what sort of money he had made each mth over the last 12 mths by selling his stored energy, I'd never get that sort of income investing the money in a short term or long term savings account, investing in the stock market at the moment is just too nerve wracking to be able to sleep at night, so investing in something that will always have an increasing market to sell to makes sense to me ......

Sooooo, you know how I'm an ideas man. How about this for an idea???

If you buy a really cheap wrecked EV with that power load grid thingy thing..... connect it to a timer to charge it during the 3 free hours, and then toggle the connection to the house to run everything outside those hours.

So, you could almost get your power for free less the daily connection charge. Not a bad idea I say. And... you don't need any (more) solar.

[supersparky]

Jon, the only hiccup with that is, is that you need a special V2G charger. That is Vehicle to Grid. Yet to be approved anywhere in Australa, and are rumours are they will be very expensive when approved.
Big issue is, most electric vehicles make 220v and some are 60hz, as opposed to the standard 230v and 50hz.
Better to just go off grid maybe.

[jon_d]

OK,

So you make your own battery and charger and inverter with a simple change over switch to power the house/charge the battery etc.

Maybe even easier.

[supersparky]

Then you don't need anything but the changeover switch Jon. The rest can be done by V2L compliant EV's. That's vehicle to load.
