1% per day is normal per owner’s manual regardless of enrollment with Rolling Energy. How are you determining the constant waking up every 30 mins or so? Do you see extra mileage loss in the Energy screen?

I have 27k miles and also getting 239 miles on a full charge so the degradation is calendar pretty much. My lifetime consumption is 205 wh/mi.

NFP is Nominal Full Pack in kWh which is usable energy when fully charged. Test needs SOC to be below 50% and I was well below. I did upgrade to 2022.36.6 from 2022.36.5. Wonder if it is a bug in .6.

Update on the battery Health Test. I was able to unlock the Gateway to start the test but nothing happened. It said all the criteria met and “Starting Test” and there was a 900 seconds. I waited and nothing happened. I tried charging the battery to 7% which then turned green from orange. Hard...

The link of the graph in my previous post is of LFP. It shows 3.2V at 20% SOC.

Starting the battery Health at 4.3% SOC. Pack voltage says 340V and cells average 3.2V. Doesn’t that indicate 20% SOC based on the graph I have seen? If the 4.5% buffer is taken account, 8.8% should be below 3.1V at cell level.

The Energy screen now has the number of miles lost while parked so the car has the ability to count the idle energy loss. I think that can be used to calculate expected SOC from NFP.

Went to the service menu this morning and looked at the battery screen. It said my battery health is 100%. I am sure it will drop after I perform the actual test tonight.

the last full charge said 243 but SMT app said 241 so you are right in the middle 😀.

Replying myself 12 months and 13,700 miles later. Nominal Full Pack (NFP) is down to 52.4 kWh. ~4.7% degradation. Energy Buffer (EB) is at 2.38 kWh, if I recall it was 2.5 kWh reserved before. Tomorrow after work, my SOC will be down to 6% (if no errand) and I will be starting the battery...

I just got 2022.36.5. It may take a week before I use up all the miles and then start the battery test. My last 100% charge indicated 243 miles. I will see if BMS could calibrate and change this value.

I was going to drive until 5-10% remaining to do the test. That should allow quicker discharge and after ending the test I would have 100% charged. I wonder how the car would discharge, perhaps by preconditioning the battery pack.

Ok, I want to do use the Battery Health Test in 2022.36.2 service menu but I have not gotten the push yet. Anyone with LFP battery gotten it? I have 2021 “Performance” SR+ with LFP.

We got our cars about the same time. I only have 11k miles. My full charge is also down to 244 miles (from 253). This may be natural calendar aging of LFP. ScanMyTesla said my full capacity now is 52.6 kWh (55.1 when new). Lifetime efficiency is 209 Wh/mi. I used to charge to 100% until I go...

I must've missed it but where does it say effective from 7/25/22? Edit: Found it in the T&C.

Here you go. https://chargeup.njcleanenergy.com/ev-charger-incentive

I am applying for $250 EVSE rebate and the application only has Loop EV-Flex and EV Flex Lite on the list. I have ChargePoint Home Flex installed so hopefully they add more chargers to the list.

Has anyone seen the battery snow icon indicating temporary capacity/range loss until the pack gets warm enough? The lowest my 2021 SR+ with LFP battery has gotten is 28 deg F and got no snow icon so far this winter. When I had my 2018 LR with NCA battery, I have seen the snow icon.

I charge when the range drops below 100 miles to full. I think the lowest I went was 20%. I would say it ranges from 20-40% to 100% charge, used to be weekly but now more often due winter.

Here is another data point from yesterday. I left home in 17F outside temp. Car was parked in my driveway, scheduled for a full charge and preheated. Battery average temp was 67 F. I drove with 67 F interior temp with jacket on, heated seat set on Auto and steering heat. When I got to work...

On my last charge to 100%, I waited until 15% SOC left and upon a full charge, I got 248 miles.

I have 3,000+ on my odometer and my full charges have been 248/249.

Yup, that's why regen is limited. Per my screenshot, 18.4 kW regen at battery temp of 50 deg F (10 deg C). That's 0.33C. The test in the paper was done at 1C and 10 deg C got 2,700 cycles with 10% capacity loss. Tesla is being very cautious by allowing only 0.33C. Yup, the middle row and right...

I get that charging to 100% would have the battery sitting at higher SOC through out it's life. I don't think it is something to worry about as there are other factors that could affect more. I have 13 years old Black & Decker VPX tools with A123 LFP batteries and they still work! My usage is...

LFP is not sensitive to depth of charge/discharge. You'll get 3,000 cycles doing 0-100% and retain 90% of the original capacity. For me, l do 20-100% cycle ~per week so 52 cycles per year so it is not worth worrying about. NCA and NMC are very sensitive to DOD. LFP is more sensitive to the temp...

Yup, the data was from my test to see how much battery temp increases after cabin temp is reached, how much energy it uses and see heat pump in action. I now do not precondition and drive with a cold battery. When I do need to charge I time it to finish before I leave home.

Max draw only lasts for 3 mins. 5.9 kW after 5 mins ramps down to 4.6 kW.

I am attaching two captures. 99.4% SOC with 31kW regen and another one with 85% SOC with 12kW regen. The difference was the battery pack temperatures, 62F vs 47F average temps. Since I timed the full charge before I leave home, I had 62F and after 8.5 hours parked, temp dropped from 66F (@work)...

Here is my last charge data for reference. I have Gen2 Tesla Wall Connector and charge at 245V @32 Amps. I set it to start at midnight so the voltage is higher. Per my Sense Monitor, the charge consumed 42.9 kWh and took ~5.5 hours. It refilled 189 miles from 62 -> 251 miles. Therefore, the...

Had a few charges to 100% since last reported. Car continues to report 251 miles instead of 252. If I add the actual driven miles with the screen reported remaining miles, I get about 242 miles so the colder weather is taking some toll but way better than expected. Heated steering wheel...

I have never charged at a Supercharger. I charged to full last night. Woke up this morning with 251 miles. I think it adjusts to the consumption data.

252 sometimes 253. I have 2021 SR+ LFP.

After the last week windy trip, my full charge dropped to 248 miles. Pic below is from four 30 miles commutes with sparse cabin heat only if it starts to fog up with 2 bacons seat heater. Daily chores to drop off/pick up my daughter/wife had cabin heat. I got 235/248 miles although I got 200...

I had 3 passengers and 3 cats at 70 F cabin. Just so I have a reference, what percentage of rated range did you get going 70-80 prior to the cold (without needing cabin heat)? Glad to hear battery preconditioning works. What's the max kW did it charge at?

Yes, Sentry was off. I am on the same version. Just got back from a trip from Bergen to East Brunswick (noon to night return). It was especially windy and zaps Wh/mi going at 70 mph on Turnpike. I mostly stayed around 65 mph. I have 149 miles with 49 miles trip yesterday, averaged 230 Wh/mi on...

Drove 49 miles round trip with my wife and daughter to my sister’s house where I stayed for 7 hours. Starting outdoor temp was 45 F and ended with 34 F when I got home. Displayed range dropped by 57 so I used 8 more miles than the car was expecting. This was due to the heat pump running to...

I have not pulled the trigger yet. I want to go hardwire so I get 50 amps instead of 40A with NEMA 14-50 (yea, misleading). Although my SR+ can only pull 32A, I may need to use it for the Cybertruck (preordered).

It may be true if you preheat off the battery. I have only preheated off the Wall Connector and I did not observe the battery temp drop. Here is 26 mins preheating with 8kW start to 6.3kW end at 30 deg F cold soaked overnight. Cabin temp was reached within ~5 mins. The rest was maintain it and...

I only charge at home and my LFP has exceed my expectation and it is doing better than 2018 LR RWD with NCA. Regen works better at similar temp (30 deg F) so far in NJ. Will see how it goes as the temp dips lower. It was able to charge at maximum speed (242V@32A) despite cold soaked in 30 deg F...

Can you take a picture of the window sticker? I am interested in the MPGe rating.

30% off $700 with federal tax credit and I can sell the Gen2 Wall Connector and it'll be ~$100 out of my pocket.

Nominal Full Pack (NFP) is 55.0 kWh and Nominal Remaining is 54.3 kWh at 98.7% SOC. I drove 3 miles this morning, 76 meters elevation drop and back up. Regen was strong enough to absorb all energy except at 5mph to a red light at the bottom of the hill. I had both front seat heaters and cabin...

I charged it to 100% overnight and this morning I got 253 miles. Car has 1,700 miles on ODO.

Right. I got Charge Point Home Flex ($700) to replace my Gen2 Tesla WC. I am contemplating if it is worth all the trouble to save 11 cents per kWh especially, I'll need to use J1772 to Tesla converter every time I charge (and remove it to hang the J1772 back on Home Flex.

My LFP gets 30 kW of regen brake at 99.4% SOC. You can charge to 100% and after driving a few miles, the regen will be fine.

Sorry to revive this thread but I have good information to save us some more money. PSE&G launched the Electric Vehicle Charging Program and I have been asking questions and have gather as followed: The charger would use RLM rate so it is ~7 cents off-peak vs ~18 cents for RS plan. I have a...

Per this paper, if you look at graph d, there isn't much difference between 20, 60 and 100% depth cycles. You still have 90% initial capacity after 3,000 cycles. 253 miles x 3,000 cycles = 759,000 miles on odometer. 786,000 if we use 262 miles per charge. This battery will go past a million...

2021.36.5.5 had improvements for cold weather. Hope you get the update soon and it improves it. BTW, I just got 2021.36.8 a few days after and tried out the Sentry Live steaming. I have not charge it yet to see if there is any difference with the battery. I only charge at home though.

There is no indication of the EPA test result for 2021 LFP Model 3. It is not on EPA website and the Monroney sticker that came with it can't be trusted either. For me, I don't care if it displays as 253 or 262 as I am getting more than 253 now anyway. The important thing is the available...

I have the same thought. Tesla sold the car with incorrect Monroney sticker. It said 262 miles range but scanning the QR code goes to 2019 SR+ page which is rated 240 miles.
