    new Tesla Model 3 18" Photon Wheels - load rating?

    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...

    First charge curve data I've seen.

    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...

    First charge curve data I've seen.

    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.

    First charge curve data I've seen.

    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...

    First charge curve data I've seen.

    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...

    First charge curve data I've seen.

    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...

    First charge curve data I've seen.

    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...

    Cybertruck AC L2 charging onboard charger specs

    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...

    Supercharger - Mojave, CA - 16870 CA-14 (Mojave Thai Cuisine, LIVE 24 Oct 2023, 20 V3 stalls)

    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...

    Trip Projection Works Great Going Up Elevation But Way Off Going Down

    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...

    Battery Strategy and Degradation at 10k Miles

    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...

    Battery Strategy and Degradation at 10k Miles

    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...

    Model 3 (Stealth) Performance - 5y ownership, service history + high battery degradation?

    It sounds like your car has been stored at high SOC (90%) for a significant portion of the last 5 years. This most certainly increased calendar aging of the battery cells verses if it was stored at a lower SOC. So even though the cyclic-induced degradation might be less, with relatively few...

    Model 3 (Stealth) Performance - 5y ownership, service history + high battery degradation?

    Unless the BMS is out of calibration, which is a distinct possibiliy, this would be very high degradation over 5 years and only 28k miles. Can you describe your AC charging and storage habits with this car? To what SOC was it typically recharged? What was a typical depth of discharge (how...

    Thanks @bmah. This has been a very unusual build-out of Supercharging in the little oasis of Mojave. At the end of this construction there will be four separate sites with a total of 56 stalls, unless they decommission some or all of the original site. For those confused, here's the sequence...

    iOS app making charge level recommendations now (4.23.2)

    The recommendations don't appear to be as simple as that. My app (4.23.2) shows the 90% recommendation for my 2018 Model 3 LR (on 2023.7.20). If there are differences between models it would likely be because of variations in battery chemistry (not BMS nor driving habits).

    2023 Model 3 has not awaken in almost 5 days to top off the LV battery, normal?

    I’m curious to hear about your phantom drain experience. You might have an issue with your 2018 car. Recently, my 2018 Model 3 only dropped from 47 to 46% after sitting at an airport for 7 days. It’s had that low level of phantom drain since at least May 2020 quarantine. From TeslaFi:

    Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

    No kidding, and your video leaves me more confused. Has there been a change to the balancing logic as stated in the Model 3 service doc shown below? Does it actually balance while charging or only discharging via bleed resistors? Here’s a screen clip from a few years ago from @ord3r. More...

    Vacation - Leave Plugged In Or Not ?

    Very high phantom drain used to be a prominant topic on this forum. Tesla fixed that many years and you're absolutely correct, an untouched and sleeping Model 3 will use way less than 1% per day. It's actually 1% about every 6-7 days and in my experience it's been that way since early 2020...

    most range efficient wheels for M3P

    Let us please not debate that a heavy wheel decreases highway range. Yes it does, but it's effect is so insignificant that it doesn't matter. Frr = Crr * N = Crr * M * g N is the normal force due to gravity and mass of the car. Increasing each wheel mass by 5 lbm, as an example, only...

    M3 Tire Sidewall

    That’s what happens to a tire after it’s driven without air pressure. It’s very obvious if you’ve seen it before. Basically, the wheel rim is riding on that spot on the sidewall wearing it down. That tire was probably driven for a few miles without pressure. I would plan to replace it...

    Battery losing charge due to vehicle standby

    Very normal. We tend to think of battery energy like a fluid in a gas tank. That it shouldn't disappear unless used. But that energy is stored as chemical reaction not a quantity of substance. As the temperature of the battery changes, the ability of the battery to discharge that energy...

    The Superchargers on this section of the 5 will remain squeezed until more are installed at the top of the Grapevine. Right now it's barren between Tejon and Castaic/Santa Clarita, with a lot of elevation change that leads to uncertainty and conservative charging. Fortunately, 63 stalls are...

    Another charging battery life thread

    No simple answer is possible. It depends. For example, high SoC degradation is temperature dependent but depth of discharge is not (to my knowledge). So in a hot storage environment you might favor the lower SoC over the higher DoD.

    250kW supercharger disaapointment

    Yes, that battery pack has more energy but there’s at least some evidence (more evidence) that it has a more conservative charging profile. Frankly, I haven’t paid much attention, maybe it’s resolved, but the higher capacity was a result of a chemistry change which could have compromised the...

    250kW supercharger disaapointment

    Since this thread is about expectations, I think it's important to mention that under optimum conditions, the Model 3/Y should only charge at 250 kW for less than 5 min before it starts to taper at around 26% SoC. The simplified math is 75*0.25/250/0.95*60 = 4.7 minutes. This is starting from...

    19" replacement OEM tires

    As mentioned in the other linked thread, this report was in error as it referred to Model Y tires, not Model 3. The 235/40R19 ProContact RX T1 tire is still available for the Model 3. It remains as probably the most EV-friendly all season tire in that size.
