What’s old is new again. The thread below has my 4-year old analysis on different loading configurations that would exceed a 700 kg rating. There are a few things I could clean up in it, but it still a good reference. Bottomline, most typical loading conditions don’t get close to exceeding a...

Here're updated graphs with Ryan Shaw's charging data from his YouTube review (at 11:00). Both these charging sessions overlap remarkably well. Therefore, This builds my confidence that this charge curve represents an optimal charge session for today's hardware and software configuration...

Per Kyle Conner, the CT has Gen 2.3 4680 cells Unknown. Lar's charging speed comment could apply to either an improved charging curve for the current cells or be associated with the NMC 955 or NMC 973 cells.

100% agree! Averaging >250kW over that window would be immense and is the far extreme from what we’ve seen thus far. This is a major disconnect and should give us hope. If this first charge dataset isn’t a fluke and represents a typical curve now, the next critical information we need is the...

I created a charging model (overlayed gray dashed line below) based on the demonstrated Model Y 4680 charging power from Branden Flasch and extrapolated that to the CT pack size. Results are below. Obviously I'm speculating, but until Tesla improves the charging curve, don't expect...

With a reasonable extrapolation, this charging curve meets Tesla’s stated charge rate spec of 138 mi in 15 min for the DM CT. 136 mi is 40% of the 340 mi total range. It should be able to charge from 0 to 40% in 15 minutes. With a reasonable ramp up to 250 kW from 0%, maintaining 250kW...

That’s basically what we’re seeing with this data. If we consider that half of the CT 122 kWh pack is 90% of that 68 kWh Model Y pack, then the “125kW” equivalent is 139 kW’s into the Model Y. That 139kW point on the MY curve is around 20% SOC. If you go back to the CT data, it’s level until...

Unfortunately, I think that 48A is the most you can expect. I looked but could not find anything more definitive than the charger provides 11.5 kW bi-directional charging, which implies a max 48A at 240V input as I think you know. The Wall Connectors they sell also max out at 48A. If the CT...

It's open. I charged. It's not yet on the car map but it cost the same as the other stations nearby ($0.36/kWh). This station is definitely an odd one, and I can't explain it all. It has 18 stalls arranged around 3 sides, with an island in the center for chargers/transformers, plus more...

Yes, this is normal. The trip projections are generally pretty good, except when estimating steep descents. The calculation appears to be overly optimistic for energy regeneration when going downhill. My commute climbs/descents ~1500 ft and it's been like this as long as I remember (5-yr...

Can you cite any technical support or rationale for this statement?

Yes confirmed (not that I need to but I used it this afternoon). It’s not yet on the screen in the car. Can’t beat the current price either.

It sounds like you're using the battery aggressively, with routine deep discharges, but have a reasonable charging scheme to minimize degradation given that usage. I don't know of a better strategy. The open question is how much do these tweaks to recharging strategies actually reduce...

It's possible your BMS has a poor calibration on the full battery capacity due to your anxiety about not leaving it at high SOC. To help the BMS calibration, do a full charge from a resting very low SOC to 100% and let it rest (2 hours sleeping). Cycling this a few times may be required. Each...
