In the Mannum solar farm case, water is the big cost and without it, they are growing rocks. This land would have been sheep grazing previously, the panels are close to the ground to stay out of the high winds and the panels track east west, so not suitable for grazing really. By selling that...

This is the solar/battery farm roughly a km away from our place That cleared block is where the battery plant has been installed over the last 12 mths https://epicenergy.com.au/mannum-battery-energy-storage-system/ Threr is another large solar farm near Murray Bridge, about 30 kms away, but...

Donald has finally convinced Daisy that tonight's the night. Up in the hotel room Daisy tells Donald, "Not without a condom" Donald immediately heads down to the concierge enquiring if they have any ... "Certainly Sir, will I put on your bill? Donald replies, "Don't be thupid, I'd thufitate"...

Naturally, Seduction is therefore the act of seeing ducks ;) :unsure: T1 Terry

That sounds about right. I think because you haven't artificially reset the capacity back to 100% being 51kWh, it is getting close to telling you what the true capacity of the battery is ..... so I wouldn't worry too much. The next SoH will not be as savage I'm guessing, and bottoming out at...

My wife has been suffering with an ulcer in her heal, and acute Achillies tendon issue. Every specialist seems to have a different idea on what or how the problems should be treated. The ones looking at the tendon problem had a whole range of exercises, a moon boot for day wear and a night time...

Sounds much like my inverter explanation, the efficiency % is when the unit is working at its designed peak performance. The loses are constant, reversing the system to generate DC at a higher voltage than the AC input, the loses through rectifying the AC to DC are proportional to the current...

Hmmmm...... so if battery health is declining, yet range remains close to the same over 41,000 mile .... as the nasally red head would say "Please explain?" T1 Terry

All of which are assuming passive balancing, though. Do we know that for sure, or could the BMS be doing active balancing? Does any manufacturer use active balancing? T1 Terry Judging by the cut and paste bits, the vehicle has done 30,000km at the moment .... in about 16mths? So maybe...

Well, that wrecks my deep and cryptic one, cause it now appears as though I got it wrong about who made it and who badge engineered ..... The Song was "Stairway to Heaven" performed by Led Zepplin. There's a sign on the wall, but she wants to be sure 'Cause you know sometimes words have two...

OK, seems not many interested or with their thinking caps on at the moment. Here is another tongue in cheek one, Staying Alive by the B Gees ;) :rolleyes: I'll post the rather deep (cryptic maybe) one tomorrow if no one wants to have a go T1 Terry

Judging by that, it seems the charger doesn't actually continue charging the battery during the balancing stage and the 80 W is used to power the monitoring side of the BMS. The charger efficiency can only be measured while the charger is actually doing just that, then it's watts in minus watts...

The theory for how Nom. voltage is determined is about as varied as how the universe came into being ..... The one that makes the most sense to me is nom. voltage is the voltage a charged cell drops to under its accepted test conditions load, this is from the Winston website and the graph shows...

Following the plot, how many yrs would that be? It will be interesting to see if the end of the graph settles out to a shallower curve. T1 Terry Is that from the supply or into the battery? Looking at it from a reverse angle, 12V to 240VAC inverters are roughly 90% efficient at close to full...

Yeah, but an equal number seem to deny it, probably Toyota fanboys and can't believe Toyota would do such a thing :rolleyes: T1 Terry

What losses are you attributing to the balancing part of the whole charging regime, the 10% in charging inefficiency would be about right, but a total loss type balancing method used by MG and the time the charging system still running yet not really charging much, so the inefficiency there...

I think those energy charging figures are what was fed into the vehicle from the charging point, not what actually went into the battery. Is this correct? Allowing a 10% inefficiency between supply and actual battery input, that comes out at around 36kWh into the battery. 80% of a 42Ah battery...

Yeah, but the thread title is "Name that Tune" so nothing to do with identifying the make or model, but what tune does it bring to mind? One I thought of was Supertramp Dreamer ;) :LOL: they didn't even make it yet they are claiming it's their first move into the EV market ..... So, what...
