more beginner videos plz! A video explaining charging speeds would be great as well!

[daveharris]

The skits in the beginning are seriously great! Keep them coming please.

[McGruff]

That was amazing. Great job explaining something that could be extremely complicated to explain.

Tailosive, I got a Model 3 LFP battery too. Watch the video made my CleanerWatts, he explains that the LFP battery deteriorate slower only COMPARED to the other battery times when charged to 80%. Tesla recommending them to be charged to 100% makes them deteriorate quicker than the rate based on nationwide batteryHealth scans. I recommend that LFP owners charge it to no more than 90% to prevent peak voltage, while still being sufficient to calibrate the BMS mileage range curve.

I appreciate the work put into clarifying the difference between battery cell types and generations as the models update and move forward. This is gonna help a lot of people decide which models to buy. It's definitely fast changing.

⁠Remember, that LFPs take lots of energy to warm up after the iron cold soaks in freezing temps, overnight. Also, when preconditioning ahead of supercharging, which meant about 2% in my Sep ‘22 Fremont NMC MYLR on my recent, chilly, SoCal to Starbase drive, so I imagine it would be more dramatic for LFPs. Also, please report on doing the Battery Health Test in the password (“service”) protected Service menu. Hint: 1) Drain battery (well -depends on newness to avoid “charge state too high”) below 50%, 2) Disconnect & set max charge to 100%, 3) Reconnect making sure charging is underway before activating the test at highest rate available (low amps takes 24 hrs bc it discharges to near 0, then 100). My first attempt failed (thus the above) & when the test completed after 24 hrs, it just displayed a Green “Health Good” with no other information I could find. 😞 So, YMMV. After 10k miles (some, up to 142MPH) I’m showing 321 range, down from 329, delivered. I understand degradation hits batteries most at beginning & end of life, so that 2.5% doesn’t seem out of hand. I typically charge 20-80% at home, but on long trips often drag it out to 100% just to allow for more napping/relaxing. Btw, after lots of flooring past 100mph & regening back below 70 would turn preconditioning off & actually yield better than estimated (in freezing ambient) kWh used! I now do that whenever traffic conditions are sparse enough to not alarm those behind. Hopefully, new battery chemistries won’t have most EVs mimicking.

I'd like more beginner videos! I've had an LFP battery Tesla since December 2022. I'm really confused because it seems like it's degrading.a lot faster than i thought i would... i've lost about three miles of range in five months. I've read that LFP degrades substantially faster, do you know if that's true?

[digarian]

Loved the skit, because I just let those parts of everyones’ videos. Thanks for doing this.

[zorlac]

Great video! Thank you for the explanation. 😊

[ALRinaldi]

I'm never going to call them 1865's, always 18650 to me! :D

[hermanmoreno]

You did excellent describing everything!

[cliffm]

Folks, if you like peace of mind about your battery (longevity & safety), for years to come, just charge your EV between 30% - 70% (and do 90% - 100% when going for a long Road Trip).

(I own Tesla S & X, and I'm an Electrical Engineer)

* High temperatures kill batteries. If you go on a holiday/vacation during the summer, leave your vehicle at a low SOC (state of charge). For example, at or below 30% SOC

* Cycle within a narrow SOC range. For example: 40-60% rather than 10-80%. The cathode expands and contracts in a wider SOC range, which causes it to break apart.

* On that note: The lower the narrower the SOC range, the better. That means charging frequently.

* Avoid charging the vehicle above 75% SOC. Above 75% side reactions start occuring that cause degradation. This also reduces the volume expansion issues mentioned

* Taking all variables into account, operating between 45-70% SOC, and storage at ~30% is ideal.

* Occasional high SOC and wide SOC range are okay! For example, the occasional road trip.

* With good thermal management hardware and battery management software, supercharging should have minimal negative effects on cycle life

But even y'all will not follow those tips. The battery will not die tomorrow. it is just that there are some small (or big) consequences later on.

Have a great day!

[andrewrance]

Great vid! Logically a reduction of thermal runaway risk while charging makes sense as the choice for commercial applications. Have the detail on the Semi's batteries been confirmed yet?

[YJI]

Good job on the skit. Really enjoyed it, as those types of people/vibes/etc definitely translate to many topics/industries lol.

[JcFiscus]

Great job organizing and simplifying the complexity surrounding the various battery chemistries in Tesla batteries.

When graphene super capacitors replace battery packs?

[MegaLifeChanging]

Great video!! Best explanation on batteries ! Thanks!

[MegaLifeChanging]

So are 2170 batteries better in cold weather?

[benjaminbenson]

What's the difference between the lfp battery and whatever other battery are in Tesla's is one better than the other

[johnkramer]

from what i heard, MY RWD and LR have about a 200 lbs difference in total weight. whcih has led to the speculation (among other things) that both have the same battery capacity since 200lbs would account for the extra motor and not much else. However, MY RWD is software locked (10-20% of peak battery capcity) and hence the 100% battery on it has less range since it is locked. would you happen to know if the battery on both (2024 models) are 2170 hence?
i doubt the MY LR in the states has 4680 NCM since the weight should be considerably higher then the MY RWD in that case (less energy dense and hence).

22 m3 rwd LFP 16, 000 miles and showing 262 miles when fully charged is that kinda drop normal at 16, 000 only supercharged once
