    How are we supposed to get est range @ 90% 100% etc. now?

    These new updates are awful. I can't adjust the SoC capacity unless it's actually plugged in which is stupid. I should be able to open the app at any point and slide the SoC to 80% 90% 100% or whatever. They appear to have also removed the estimate of range that previously existed. So, even if I...

    Is it okay to discharge a battery bellow 20% for a short period of time?

    Hi all, I know the rule of thumb when it comes to SOC is 20-80% and it is okay to go above 80% for a short period of time like before the long road trip when your battery will discharge bellow 80% after an hour or so of driving. However, when it comes to the lower level of SOC, is it okay to...

    Accidental disconnect wouldn't let me finish charging to 90%

    Due to "high usage" Tesla lowered my charge limit from 90% to 80%, so I set it back to 90% and went shopping. When I thought the app showed 90%, I walked back to disconnect; but I misread the 80%. I didn't know because I just unplugged my car upon arrival; when I opened the door, I saw it was...

    2x Powerwall on 2-phase UK supply: sensing PW SOC individually

    I would greatly appreciate it if anybody has the answer to a bit of knotty problem I am trying to sort. SitRep. Had 1x Powerwall + 1x Gateway 1 + 1x solar array on a single phase UK electricity supply for about 2 years. All working fine. Have recently upgraded to 2-phase grid supply with our...

    When I last ran out my battery..

    Pick the largest category that fits your situation. Do not count as a 'shut down', a situation where you arrived at the Supercharger, and it failed to produce electricity -- and you had to go hunting for charge. Also, don't count situations where there was a mechanical/electrical problem in the...

    Roadmap wish item: Powerwall/S3XY optimizations for charging

    The recent software feature updates to charging behaviors when there is a grid outage is a good start. But, something I would appreciate having the ability to do through software and associated communications is to charge my vehicle after and only after the Powerwalls have had their fill for...

    Model 3 Performance Dyno Test: Binned Motors?

    We finally got an AWD car on our dyno (thanks to our friend Shereef for lending us his P3D) and it was great to find that these cars will work with a Dynapack hub dyno without issue! After seeing the difference between the standard and long-range RWD Model 3, we were very interested to see how...

    HW and SW Redundancy in HW3

    Today in a tweet, Elon Musk eluded to hardware and software redundancy coming. He then further clarified a question about how this will work: A few questions come up as I think about this: 1. Will each SoC run identical versions of the OS and NN? - If so, will this potentially open...

    Ideal SOC for limited driving

    Hi friends! I bought a new MS 75D in June 2018 and to date have about 8,500 miles on her (a lot for me - but I've been enjoying the ride and drove a lot this summer!). I have done a lot of reading and research on the battery, charging, etc., and after initially charging to 90+ percent I have...

    Body shop damaging the battery

    So a while back, I was rear-ended while stopped in my Model X at an intersection, while an ambulance tried to cross. The damage was relatively minor, but given that the bumper contains a lot of tech, my insurance estimated the repair at 70 hours of labour. Since there wasn't a "Tesla certified"...

    New battery charging tip from service center

    My S75RWD has been losing rated distance at a rate faster than expected, and it only started happening fairly recently. I'm down about 5-7% after 15,000 miles, which I know isn't totally out of the ordinary. But the odd thing, is that sometimes 90% will charge to 210 miles, other times it will...

    Destination SoC vs RM

    Driving from Twin Falls, ID to Idaho Falls, ID, I stopped at the Twin Falls SC and charged until the Nav system said I had enough charge to continue my drive and would arrive Idaho Falls with 12% SoC. By subtracting the estimated distance from current RM range, I calculated I would arrive with...

    [Rumor]Tesla is reducing speed of Supercharging as your Tesla gets older

    As your Tesla gets older the maximum kW you experience while charging at the SuC will drop and charging take longer. Unofficially several Tesla employees have explained this as a limitation that has been implemented to protect the battery, but the details of the "algorithm" seem to be unknown...

    Should I charge to 100% (night before trip) if my first supercharger stop is only 80 miles away?

    I understand that you actually supercharge faster the lower your SOC when you arrive at the charger. The first leg of my trip will only be 80 miles, so I'm wondering if it really matters if I charge to 100% the night before or if 90% is better or won't really make a difference. I have a MS 70D.

    Max Power vs State of Charge and Temp

    I've been collecting data from various threads in an attempt to understand how battery Max Power varies with battery State of Charge (SOC) and temperature. Here are the results so far: Since receiving my P90DL, I've been able to add some of my own data including a test of how the max power...

    SOC Setting?

    I'm curious what Tesla recommends and then what folks have been setting their overnight SOC to. I understand the range charge (100%) is only done once in a while or when you're expecting to make a long trip. But, what do you set as your TYPICAL overnight, weekday, going to make my commute...
