    Model X 100D Battery Internal DC Resistance

    Several days ago I’ve driven on a mixed road including hi-way for 48km and recorded the data by Scan my Tesla. After I plotted the chart I though why not calculate the internal resistance of the battery. Extract an 8 minutes section data when the power change seems to be the most. Modify the...

    Charging off whole home Generac generator

    Came home to no power. We have a 21 (whatever) whole home Generac Generator. Anyone ever charge off one of these before I plug in and take down the local grid?

    2X range reduction vs. miles traveled

    Curios if any other MS60 owners run into an issue where range reduces at a rate of nearly 2x actual miles traveled. For example, my commute into work is 2.3 miles, but I'll lose 5-6 miles in range. Temperature outside is in the 40's, and I dont have the car heater on. My wh/mi average often...

    Lack of “Always Connected” on Model 3 causing noticeable vampire loss

    Wanted to share observation that api/ logging tools on Model 3 disables it from sleeping. Some tools are better than others, though anyone polling the apis at a minute or less refresh rate may cause in the order of >5% loss per day. I believe if/when “always connected” mode is enabled will...

    Problems with 120v charging

    I want to know any downsides to 120v charging – beyond the obvious slowness. I'm about to be the proud owner of a 100D. I'm also retired with nowhere to go every day. I've searched this forum for information about charging, and specifically 120v charging. The consistent advice is: “Don't waste...

    Congo is to the electric car as Saudi Arabia is to ICE cars?

    There’s a Global Race to Control Batteries—and China Is Winning And China has its hands all over Congo and its cobalt supply. GM is supposedly moving to a 811 Li-on battery (less cobalt) for its next gen BEVs due in 2021, and Nissan's 60 kWh 2019 Leaf will supposedly have the 811 battery. LG...

    Total Energy released in battery fire

    hi all I’m wondering what the total energy that gets released in a battery fire. Assuming it is a lithium ion battery as used in Tesla EVs. Assuming that the battery is fully charged. As a non battery expert, and a non chemist, I am making a guess that the lithium will oxidise, releasing the...

    Almost made 60k on 12v battery

    40 miles short of 60,000 and my 12v warning lights up. Still under warranty! Stupid car. I've had the same yellow top in my 09 Tahoe since... 2009! with 130,000 miles.

    2015 85D Increased range from 435km to 536km.

    I am new to the site. I thought I should share my last weeks experience of a 100 km range increase. I emailed Tesla help and they responded saying "Tesla is constantly recalculating and getting firmware updates. There may have been an update that was able to extend the range of the battery"...

    Checking out a well used battery.

    Besides looking at 100% rated miles, is there anything I can do when looking at a used Tesla to determine the health of the battery? When I bought my leaf I used an OBD2 reader to get info from the BMS. I'm going to inspect / buy a 2015 Model S 70D with 70k miles on Monday night. Are there any...

    What are those 12V voltage spikes when idling?

    I performed some idling consumption tests before by Scan my Tesla but the CAN bus always shut off after about 1 or 2 hours making it impossible for long duration test. Several days ago, I started the test again but this time I measure the voltage of the 12V battery directly and here are some...

    I live near Green Bay, 2014 P85 charged at 24amps on 30amp circuit, parked outside and work is completely exposed to winds, commute is all of 7miles each way, sometimes a lunch trip or errands after work. I hate the way the car drives with Range Mode on in winter, the power limited and lack of...

    US Tax credit for wall connectors extended through 2017

    (CORRECTION: 2017) US retroactively extends tax credits for charger installations, electric motorcycles and fuel cell vehicles through end of 2017 I installed mine Jan 4th, 2018. I hope they eventually keep this going for 2018 also.

    Leaving car at airport unplugged

    I will be leaving my 75D at Toronto airport parking for about 10 days . I hope to have about 70% charge when I leave it. I estimate the average temperature while away t to be -10 Celsius / 14 Fahrenheit How much drain should I expect to see over the 10 days. Trying to figure if I'll have...

    "Less energy is available due to cold battery" trying to charge

    car ate 20 miles over 2 nights parked at train station. Had 35 miles when I parked, came back to 12. Fortunately there's a level 2 charger nearby 1/4 mile but it ate 4 miles getting there. Now I'm sitting here on a 30A/240V trying to charge enough to get to a supercharger that is 15 miles away...

    Any benefit of Tesla home charger vs 220 outlet?

    I am a new Model X owner that also purchased the Tesla wall charger to have installed in my garage. Before installing I discovered that I have a 220 outlet and can plug into it using one of the adapters that came with the car. My question is whether there is any reason to install the Tesla...

    110V charging w/ Tesla provided cable

    I have maybe a dumb question. I have tried a few times to use the Tesla provided cable (that comes with the car), to charge on a regular 110V outlet in my garage. I plug it on the wall side, the green light comes on, and when I connect the other end to the car: pop! It clicks out. There is a...

    Self-Driving Cars Using Crazy Amounts of Power is Becoming a Problem

    All the data needs to be combined, sorted, and turned into a robot-friendly picture of the world, with instructions on how to move through it. That takes huge computing power, which means huge electricity demands. Prototypes use around 2,500 watts, enough to light 40 incandescent light bulbs...

    Scheduled Off Peak Charging Model 3

    I used a Juice Box Pro 40 for home charging. It is set for 11 PM (off peak charging) and I simply plug in my Model S with scheduled charging turned off in the car. I expected the same from my Model 3 but was surprised when it did not charge overnight. Tesla sent me a work around which is to...

    Understanding supercharger charging rates

    My last road trip was almost 2 years ago in my P85D, so perhaps things have changed. But I seem to remember getting a faster charge back then than I just experienced on a trip last weekend. Of course back then the charge rate was shown in amps, and now it is shown in kW, so I guess a bit of math...

    Can I do a long road trip soon after getting my new car

    My Model S 75D is scheduled to arrive 3/12/18. I'm considering using it to drive 2000 miles from the Boston area to Colorado in early June. Does that give enough time to work the bugs out of the car? (I'm old enough to remember the bad old days of Detroit cars which often spent the first month...

    Motorized chargeport retro-fit to Classic model S?

    Anybody successfully install a newer style (motorized) charge port into an older car that had the pop-open-only door? This is all pre-facelift era stuff I'm talking about... maybe the motorized door has gone through a couple generations since, I don't know. But you'd know if you dropped...

    Power Consumption and Milage

    I've noticed that Angel (my Model X, 75D) "wakes up" as I walk around in the house near the door leading to the garage. I can tell because the DRLs are turned on and from the sound of it, it's pumping up the suspension (it parks in "high" mode). I can't help but think this wastes power. Is there...

    Battery Degradation

    I am seeing several used Model s's this week with a view to purchase. While I think I understand the battery display, I need some advice.

    NEMA 14-50 above drywall

    Charging Model S vs my model X

    My model X has been in service for almost a week now... Today I took the loaner Model S 85 they gave me, to a supercharger. To my surprise, the loud fans that typically vibrates my whole X once I reach about 80%, didn't make a sound, even though I charged to almost 100%! Anybody knows what's...

    Tesla Wall Charger

    My other post is about getting the NEMA 14-50 plug. Now my question: is there any reason other than higher rates of charging to get it? I won’t be able to go above a 50-60 amp circuit. I did try a search and I’m not electrically inclined, sorry if I sound ignorant. Thanks for your help

    What is the purpose for having two pumps for the battery, is it redundancy or extra coolant flow.

    Tesla SC says no Upgrade to High Amp Charger for early 2017 MS

    Extension cord? Probably been asked before

    Probably been asked before,but still nervous. I have an S75D. I also have a 15meter 12 gauge 3 wire 15 amp outdoor extension cord. Am I safe to use that with the UMC in a 120 volt AC wall outlet in a garage where the UMC cable won't reach?

    Grid Support from Tesla cars

    Instead of more centralised batteries like the one at Hornibrook SA (!00Mwhrs) why cant we use our own parked cars? You would need three phase power, cooperation from Tesla & compensation from power companies. However you would also be able to charge at Chardemo levels 50kWs. Ill assume that...
