    The few times Tesla has addressed battery degradation, they have simply lied and dismissed it.

    You mean you cycle from say 95% to 80%? That's not the optimal practice.

    The few times Tesla has addressed battery degradation, they have simply lied and dismissed it.

    Higher state of charge on average and 50% supercharging doesn't help on preserving battery life. The "million mile battery" was a very high purity NMC battery developed in Jeff Dahn's lab and not charged up to as high voltage as usual for NMC, and was measuring cyclic aging rate. It wasn't a...

    How is my LFP battery holding up after 2 years?

    It certainly does for me. I've had very little degradation over the second year. In the battery research literature they model calendar aging with time as approximately sqrt(T). That is sometimes an approximation to something else much more complicated but the actual chemistry and physical...

    Review: Hankook iON evo AS vs Pirelli AS+ Elect vs Michelin PS 4S vs Michelin PS AS 4

    Wet performance was often quite opposed to high efficiency. I don't know the chemistry and physics involved but it was a continuous issue that low rolling resistance tires were poor in wet. If the Hankook iONs are good in wet and still very high efficiency they have a real tech breakthrough.

    How is my LFP battery holding up after 2 years?

    There is still more calendar aging at 100% than at 60% for LFP. There is the same step as NCA, but the step is at a higher SOC. There are some long threads on the Model 3 Battery subforum. Lots of discussion including multiple peer reviewed chemistry articles...

    Is Elon thinking of REHIRING some of the fired SuperCharging folks

    And you don't know which ones really were truly productive and needed because you fired their supervisors too. And all the best ones with more options go to other employers. And the worst ones who are able to lie the most convincingly work to get re-hired. And there's mass chaos and lack of...

    Direct 18" vs. 20" wheel comparison for efficiency

    I really want a "Touring" version of the 3P--- comfort tires and wheels with all the other upgrades. I now understand why the oldies used to get Buicks. Dad has old Benz sedans. Maybe I'm turning into them.

    It looks pretty bad for Luminar unfortunately. > As disclosed in Luminar’s earnings report on Tuesday, in the first quarter of 2024, Tesla contributed over 10% of Luminar’s revenue, totaling more than $2 million That means they have few lidar sales so far and the biggest customer is one that...

    Direct 18" vs. 20" wheel comparison for efficiency

    This is consistent with an academic test I saw. In a nutshell, the aero efficiency was strongly correlated with how much of the overall wheel + tire area was covered (better) vs uncovered (worse). So when people compare 18" to 20" tires the main difference in efficiency is because in an 18"...

    Model 3 SR+ LFP Battery Range, Degradation, etc Discussion

    Determining capacity is much harder in a LFP battery than a NCM/NCA because of the flat voltage curve. It probably did a recalibration, but maybe poorly. It's a bit risky but try driving down to 10% or less and letting it sit in sleep (no sentry no remote access, nothing) for a few hours...

    Model 3 SR+ LFP Battery Range, Degradation, etc Discussion

    Looks like 65% charge limit is pretty reasonable to do to get the 62.5% SOC curve for calendar aging which is pretty good.

    FSD 12.3 today - utter failure!

    What situation is this? When do you have a "U turn" next to a high speed lane? Is this a divided controlled access road? TBH I never seen something like this driving in California in a freeway. Nearly all U-turns on roads would generally avoid the median and there'd be a dedicated left/u...

    Regret purchasing FSD after the Ver 12 "upgrade" being crammed down my throat

    it's more that people are thinking they are under manual control but the car accelerates on its own. I experienced that early when disengaging rolled back from autosteer to TACC when I wanted it to turn off. I think it implies arbitrary and probably unfair regulatory scrutiny and regulators...

    PIRELLI P ZERO ALL SEASON 235/45/R18 - Are these decent tires?

    In that case go for it. Tesla shipped a 94 SL tire, the Hankook Kinergy GT (not a great tire) with the Model 3 for a while instead of the MXM4. 98XL isn't needed. They're now using a different and I presume better Hankook with a special Tesla OEM version, Hankook S1 All Season with foam, in...

    PIRELLI P ZERO ALL SEASON 235/45/R18 - Are these decent tires?

    Can you get the PZero Elect version? What you found is the 'generic' non-EV tire. It's probably fine but will have more noise and lower efficiency than the EV specific version of the tire. The price is attractive and if you aren't set on EV specific tires, go for it. 94V vs 98W is probably...

    Regret purchasing FSD after the Ver 12 "upgrade" being crammed down my throat

    Ah OK. TBH I found autosteer to be more reliable and predictable than the TACC. There are few cases of 'phantom swerving' on the highway. Before FSD 12.3 I would want Autosteer but manual acceleration. With FSD 12.3, setting chill and minimal lane changes with no nav destination is sometimes...

    It probably isn't like other charge networks. It has much more use, much more efficient capital expenditure and lower maintenance costs. 9 months of expenditures in return for decades of revenue from the chargers. That's short sighted thinking---the demand will continue to increase. How did...

    No, only if they are on domestic residences. Nobody is going to spend 4-5 hours in a random parking lot. 20 mins, maybe. The answer for urban demand is forcing apartments and HOAs to agree like California does.

    That's still bad management---if you had a manager under you, some random "Herbert Wankerman" and not "Elon Musk", who did the same thing to his teams in a critical function, would that be considered a wise and effective choice? Surely not. It's very much "bossy" behavior and not...

    Model 3 SR+ LFP Battery Range, Degradation, etc Discussion

    And contrary to general popular opinion, the calendar aging for LFP also increases with higher state of charge and it's best to keep it under 60-65% for most of its life. Sure, charge to 100% occasionally for calibration, but don't do it every day and don't leave it there for a long time.

    He used to be like that (2018 and before). Today he is dominated by his emotional swings and narcissistic needs. He bought Twitter because he was pissed off that some kid was tracking his jet from public sources. "pedo guy" and raging at SEC and tanking Twitter are not part of any long term...

    I think it's actually more consistent with persistent amphetamine abuse. I think he started doing uppers (surely a legal Rx from a shady doctor) around the time of the Model 3 "hardcore" factory ramp. He bragged about how much he was working. And yes in the short term the drugs will let you...

    The diagnosis here is also Ballmer syndrome. Pure, raving jealousy of something else that's hot and he's not. Back in the 2000s when Apple and Google and Facebook were taking off and Ballmer's Microsoft was always leaping to try to copy something else poorly, but with horrible internal...

    Unfortunately I think it's major personality defects.

Maybe she talked to the Board about Elon? What if Elon ordered her...

    Does Minimal Lane Changes This Drive + Minimal aggressiveness option not do enough? Also clearing a navigation target will have it generally just drive straight unless manually signaled.

    Some new data from research on Tesla model 3 cells

    You don't. You appreciate the long range you have maintained optimally through your otherwise diligent battery management. Then make it so. I suspect (AAKEE appreciate your opinion) that L2 charging to 100% and avoiding a supercharger stop will be superior for battery life than the reverse.

    Some new data from research on Tesla model 3 cells

    Because probably cyclic aging from 85-100% frequently is also a problem and regen is limited at 100%. And when people charge to 80% on average across the fleet they will spend more time below 55% than if they charge to 100%.

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

    Then why don't they have 82 kWh like the other Panasonic NCA packs? That's the question. Particularly with the less efficient Y they would want to have a higher energy if they could.

    Some new data from research on Tesla model 3 cells

    Agree. This message works fine with experienced EV owners who have charging at home (like me) but Tesla (and everyone else) needs to sell EVs to non EV owners. And there is plenty of ignorance and emnity ready to jump on and twist any such statement. So to the automakers there's too much risk...

    This defers decisions about hardware needed for full autonomy for a later date, but there's little chance of achieving good unit cost figures with a bespoke robotaxi-and-nothing-but platform.

    yes it did---it simulated tons of outcomes and used those to train. The span of unknown and unpredictable situations is much larger and simulation doesn't cover it. They do have simulation now. The simulations with generative ML tools also need lots of high quality data to train with.

    I don't think that will work either---regulations or liability. Is each car owner going to be able to take off work for an emergency to fix a tire, deal with a customer in person, find a tow truck, and get screamed at by drugged up karens and kens?
