No need to ask any questions. If he’s a friend simply tell him he does not own enough TSLA.In an amazing coincidence, I am going to be chatting today with a battery research engineer friend who happens to work for, wait for it...

What should I ask this person?

Good, cuz I wasn't sure where I could park it.It's sold out already, we waited too long to discuss it!
Looks like a good bounce off that levelTime to re-test the 1060 support...
SOLD OUTOn second thought: my guidance was probably too harsh, so go ahead and discuss the Cyberquad. But don't go overboard.
It's a toy, not made/produced by Tesla. It is made by Radio Flyer (same people who made the mini Model S and Model Y), I feel very confident in saying that there is zero Tesla tech in this product: Ride-On Tesla Toys for Kids | Radio FlyerOn second thought: my guidance was probably too harsh, so go ahead and discuss the Cyberquad.

SOLD OUT
Even just getting it started in very low production would be huge. Tesla does have a history of seeding the market with low numbers to get buzz going (see model Y shipments to Europe).Just piecing some information together.
Tesla rejected a $1B+ incentive in Berlin, for which part of the conditions was that the factory must be the first to utilize 4680 cell.
Now we are bombarded with CT merchandises and hints that something big may happen on 12/9. Could it be Elon decided to use the current 4680 cells in production on limited CT production, which would prevent them from going to Berlin?
Um. That's a little odd.There might be something to the Porsche battery story.
For what it is worth, analog voltage measurements have to be converted to digital format to process them in a computer. The device used to do this is an analog to digital converter.
The digital output has a finite number of discrete steps. The number of steps that the device is capable of are typically smeared over the measurement range.
If you use the same device to measure 800V as is used for 400V, the step size will be twice as large - perhaps too coarse for ideal operation.
Amazing number considering how many more boats left Shanghai so far this quarter. Aug (2nd month of quarter was like 31k), so I’m expecting at least 35k exports minimum but I think 40k is more likely
No hail Marys needed here. I sold a chunk of TQQQ to make room for a June '23 call.Elon, forgive me.
I sold 5% of my stock and bought options.
I will wax my car as penance.
How about exports? Are they broken out, or included?
Um. I agree with you about cutting blocks of cells in/out of a group in parallel. But I have a quibble about voltages and such and where they come from.I'm not seeing an issue:
Gruber cuts out cells on Roadster blades to repair packs.

Electrically, cells within a group charge in parallel. Linguistically, all cells charge simultaneously which is synonymous with 'in parallel' as opposed to sequentially (or half of the 800V pack at a time to match 400V chargers which is not how this system works)
As to the process: Taycan is a 2p setup so they can cut out the problem cell and its mate, then jumper around them. If the pack is under rated in terms of capacity, then this mod can be hidden by a software calibration tweak.
As to the potential root cause: When a pack is nearing full charge, the key parameter is the voltage on the highest SOC cell. The charger must throttle back current to ensure this cell does not exceed design spec. If the charger output exceeds the BMS balance capability, then the cells will be overcharged.
Possibly, the charger does not regulate current output well enough (inherent issue or poor regulation from mains fluctuations).
A current reading of less than its actual output would be my guess. Resolution of measurement (precision) is less critical than accuracy (or at least the correct bias of accuracy). Better for the output to be undercurrent/ undervoltage than over.
