    Vampire Drain for Cars Long-awaiting Delivery?

    Hi all, Like many from Texas, I'm in the boat that my car has been manufactured since mid-July, and I'm still waiting to take delivery as my delivery dates are rescheduled, and then rescheduled again. One of the thoughts I had was what is happening to the battery in my car sitting on a lot...

    Very cheap CAN BUS reader with Arduino UNO, Battery Voltages Example

    Hi all, I have replied on different posts and thought it might be good idea to have a centralised place to put all info on how to read CAN bus from an Arduino UNO. The advantage of Arduino UNO + CAN BUS MCP2515 is that it's very cheap, you can get all components for around 10$ if not less...

    P100d X Full Charge - 161 miles

    Ok what am I doing wrong? I knew I was going to be running from softball game to soccer to softball to soccer today so I put the charge at Max. Put it on chill mode, range mode, and 60% was on highway (75mph average). I know going 75mph causes much more drain, had to do it because of the time...

    Wifi related phantom drain

    I've experimented with a few ways to reduce phantom drain, which was an issue when I first got my car in June (I don't have charging at home). Generally, since the 2018.24 version of software (i'm on 2018.28 now), the drain has declined to <1% (1-3 miles) overnight. However, I've discovered...

    I'd love a Model 3, but unsure my conditions (charger availability and weather) are good enough

    Hi everyone, Considering getting a Model 3. I’m aware the batteries loose efficiency when cold, but here’s my situation... I rent an apartment and have outdoor parking only. Also, I can’t install a plug, no outlets outside (not even 120V) and I don't own the place so I can't really modify it...

    New Ownership Impressions and Advice

    I love the car, it's faster than expected. Solidly built. Intuitive, if you play with the menu screen while it's parked first. Definitely needs a home charging station installed (at least a 240V plug). Here's a detailed review after picking up the 2018 Model 3, and the first 300 miles driven...

    Losing 3.5KWh sitting in garage for 24h? Normal?

    Hello Tesla peoples! Enjoying my month-old Model X 100D, and just returned from a trip where the car sat idle in the garage while we were away. Each day there was a loss of 3.5 KWh and about 11 miles of range. Is this normal? Should the car go into 'sleep' mode? I have pre-conditioning turned...

    Am I experiencing degradation already?

    I picked up my MS 75D three weeks ago today. Charged it to 100% overnight as I’ve got a long trip today. When i woke up this morning the full charge is only 251 but I thought it should be 259. Car only has 1100 miles on it charged almost exclusively on 110 outlet for first week and then NEMA...

    Cell format discussion - Cylindical or Prismatic or Pouch?

    A sTesla seems to be increasingly distinct in using cylindircal cells, are others making a mistake by mostly using Prismatic cells eg Jaguar iPace? Or is Telsa committed to cylindical cells for historical reasons and reluctant to change solely due to tooling setup costs? what are the...

    200,000+ Mileage Club

    I don't think there are many of us, but I drive 1,000 miles a week. I passed the 200,000 mileage point, so I thought I would share info on my small worn-out 60 battery. My FULL charge is 170: My 80% charge is 151: I drive fast, but my average usage is 352 Watt Hours/mile: I charge...

    Optimal battery management

    I bought my used S85 with the intention of having it for 15 or 20 years. That means that, while Tesla have done a good job at putting in systems to reduce battery degradation regardless of user habits, I am keen to do everything in my power to minimise the degradation. Am I right in thinking...

    Anyone have experience supercharging a warm battery in cold weather?

    Hi, I'm hoping a Model 3 owner can answer a question for me, which I unfortunately haven't been able to find a direct answer to (as I still don't own an electric car, but am in line for a Model 3). I've seen many counts of annoyed owners charging depleted, cold-soaked batteries at...

    Degradation is happening too quickly

    Hello all, I have a Model S 90D that was shipped to me in December of 2017. At that point the range was sold to me and marketed as 296 miles and I would top off at either 296 or even 297 at times. Per everyone's suggestions, I would rarely charge it to 100% as to preserve the longevity of the...

    Stronger, more aggressive Regen?

    Over the past week or so I've noticed my Regen is a little stronger than usual. It's been really cold where I live, and after I precondition for 45 minutes or so (with the new battery warming feature) and when I leave, I still have the dotted lines for limited Regen (pic attached) but it seems...

    Charging a few times a day to stay 50-70%

    My daily schedule has me flipping and flopping back to my house 2 times a day. Usually I leave the House with 70% or so, then I’ll get back with 40% or so, plug it up and charge to 70% again, get back home and let it charge back to 70% for the next day. So I’m going through 2 plugups a day to...

    Questions about Software limited batteries

    I have a 2017 MS 60D, and have some questions about how software limiting the battery is done, and what it really means.. 1) Since the battery is actually a 75, how is the capacity reduced? I have heard two different stories about this. One, that a module is 'turned off', and that they do...

    Charging Question...

    So I've had my vehicle for about a month. I plan to keep it for a long time (hopefully 10-20 years) and am very interested in preserving the battery as long as possible, as I'm sure many others are. I've read a ton on this and have found that the general consensus is 50-90 percent for day to...

    Anyone else think the quoted range is less than capacity?

    After watching the livestream and thinking about it, does anyone else think the quoted range is not at Max capacity? 85 or 90% perhaps? Considering there is no badging and it seems they are marketing this vehicle to folks who might not be like a lot of us and examine every detail of the battery...
