    Autopilot 1.0 and Battery Questions

    My son purchased a new Model S and I have been looking at the used inventory every day. I have done much reading but want to be certain of two aspects of the car: 1- Am I correct in assuming the autopilot 1.0 is the same as 1.0+? 2- Is the difference between the 1.0 (or 1.0+) versus the 2.0 the...

    Charging port

    I've had the M3 for about a week now. All seems to go well except for a few issues with the charging port: 1. The mobile app keeps saying the charge port is open even though it's not. 2. The button on the supercharger connector doesn't open the charge port. Anyone else having similar issues?

    Regen in cold weather -- any differences from S/X?

    Now that we have some Model 3 owners on the US East Coast and/or going on road-trips, and since they are also likely S or X owners, wondering if any differences have been seen in Regen behavior after the Model 3 has been cold-soaked, compared to S/X? From research here, the S/X will have zero...

    12 volt failure

    I have a December 14 p85d w 35k I just received a low battery warning. Do you think Tesla will cover it under warranty? Is it best to replace it myself or could there be an issue with the charging system. My two previous model s had their batteries replaced under warranty but they hand less...

    Loud humming noise while charging at supercharger

    Today when I was at the Strasburg, VA, supercharger, I heard a loud humming sound that was possibly coming from the frunk area when the rate went up to 304mi/hr. I was at the same supercharger the previous day on my way to Blacksburg, VA and did not hear any noise. i noticed at least 297mi/hr...

    How is the dashboard battery % calculated?

    Is there any information about this anywhere? I started wondering when I had to charge to 100% a dozen times or so on road trips and noticed the first 10-20% of the battery drops much faster than the Wh/mi measurement suggests,then levels off. This significantly affected the initial estimated...

    DIY Lithium battery project(s)

    As I couldn't find a thread about I figured I would start a thread about it. For the past few weeks I've been working on my first DIY Lithium battery project using 18650 cells from Samsung. I have a old Chinese e-scooter which had 4 12V 40Ah batteries and after they died I decided to replace...

    Cost of Supercharging?

    Since Model 3 owners will not get free supercharging, are there some resources available for us to see if this is really going to economical?

    wk057 Tesla Model S Battery weight

    Do any of you out there know if wk057 weighed the model S pack when he did his teardown.....or the Model S 100. If he did I can't find it. Perhaps he just weighed 1 module. That would help as well. wikipediia has the weight of the model S 85 battery as 1200 lbs but I'd like a second source...

    What's inside the Gen 2 charging adapter

    For the sake of science, I took apart a Model 3 Gen 2 NEMA 10-30 adapter to see how it communicates the charging current to the UMC. The Gen 1 adapters which have been used for Model S and Model X achieve this by means of an internal resistor connected between ground and the communication pin...

    Any value in varying charge rates on a daily/weekly basis (other than at 80%)...

    I've read a bunch and understand that for best long term battery life, it's best to not charge the Tesla past 80% on a regular basis... My question is if there's any value on charging to different %s - but under 80% - on a regular basis? Aka, I come home and plug it in and it stops at 80 -...

    HPWC drops to 40 amps after a few minutes....

    So, I haven’t posted in a long while. I’m on my third model s after 5 years (I’m telling you this so you know I’m not a newbie). I have two HWPCs with 100 amps in and properly configured. This past weekend, I noticed that my 2015 P90D charges for a minute or so at 40 amps, goes up to 80 amps...

    2012 P85 Pack Replacement

    So I was informed yesterday that my pack would have to be replaced. This is somewhat welcome news as I have had some issues with regen. My question to the folks here is who else has had an A rev pack replaced somewhat recently? What did they replace it with? Were you able to supercharge at 120KW...

    Cold Weather Got Me Thinking ahead about Battery Replacement

    Let me start with I love my Telsa. I have not illusions about the battery lasting forever. I have seen a regular and expected degradation of the battery over its life and that to date has not concerned me. With that out of the way, this recent cold snap (-4 degrees F) stole 10 miles from my...

    Supercharging rate/taper curve?

    My apologies if this has already been answered somewhere, but I didn’t see it. Has anyone validated and published what the supercharging rate/power/taper curve looks like for the Model 3?

    Early 75/75D pack degradation

    There has been a lot of discussion on this board about the higher than expected degradation of the 90kwh packs. I'm curious what other owners are experiencing with the 75kwh packs that were produced during the same time period. It appears they used the same cells, so it likely makes sense that...

    P85DL battery question

    Can someone please help me decipher this: I recently purchased in March 2015 P85DL via CPO. Out of curiosity, I just looked at the battery sticker and saw this. This looks like a replacement battery to me. I was also surprised to see that the Ludacris update is noted at the top of the...

    Model X 100D practical range

    Just took our 3 week old Model X on a local road trip in Southern California. Before starting out, we charged the car to 100%; mileage range reading 295 miles. We drove the car 238 miles and returned home with 37 miles left on the battery - meaning battery range is about 275 miles. We averaged...

    Remotely activate Energy Saving mode

    Was thinking about vampire drain (M3OC has a topic about excessive drain, also reports from Norway). And I came up with just a software update. Tesla could add power saving (with connection drop) mode selection in the app (to all models, S, X and 3) So if vehicle is left alone for long, owner...

    Adjusting charging amps remotely?

    Is there any way, with the Tesla or any 3rd party app, to modify the charge rate remotely? Here why I'm asking: I have solar panels at home. We are in one of those unfortunate areas without Net Metering. This time of year purchasing electricity from Xcel costs about $0.10, and if I produce...

    Quite a difference between 120 and 240 volt charging.

    While looking at the charging chart here: Model 3 NEMA Adapters I see there's quite a difference in charging rate when going from the 5-15 and 5-20 120 volt plugs to any 240 volt plug. You'd think the miles per hour of charge would just double when going from 120 to 240 volts at the same...

    Supercharging station constant usage Is it BAD for Battery life?

    I owned my X100D in less than 2 weeks now. I don't drive much during the week but I do make a trip to central coast california every week. There is a supercharging station just down the street from my house. What I typically do is charge my X to 80% on Sunday and this would last me until...

    1st Gen 170k mile 60kwh Model S upgraded to 75kwh

    In early 2013, I took delivery of a 60kwh Model S and in 2015, I had some battery issues which caused my service center to send my high-voltage battery pack to be remanufactured. In the interim, I was given a 60kwh loaner battery. After two years, I asked the service center about the status of...

    Blue-ish fluid leak

    Can someone explain Range Mode?

    hi there I am considering a Model S and comparing 100D and 75D. I wondered what effect range mode has and can't seem to find much written. I imaging 100D owners might use this feature less frequently than 75D owners. a) what does Range Mode affect? As far as I can tell: - Battery is heated to...

    Current fluctuation with new UMC

    Weird behavior of a new UMC that the Tesla service center gave me about a month ago in exchange for a perfectly working one. As you can see in the video, 35 seconds after starting to charge, the current reaches the nominal value (32 A), but then, 1 min into the video, the current starts to...

    Is a slow charge with HPWC normal >90%?

    Currently trying to charge my battery to 100% after charging it to 90% last night. In the last hour It went from 338km (90%) to 360km, out of the 381km 100% charge. I know with Supercharging it tapers off. I thought regular charging would allow it to go all the way at full speed? My app is...

    amazing balancing after 145k miles

    This morning I got in my 2014 S 85 with 145k miles on it. I checked the difference between the highest and lowest cell and it was 0.002 Volt. That's a difference of 0.05%. I think that's absolutely amazing and shows how well Tesla's BMS works. Amazing!

    Very few Super Chargers in the Fremont/South Bay
