efficiency

Hi TMC, TLDR: Charging now starts at 6mph and a reaches a steady 7mph on NEMA 5-20! Details, AKA why would anyone do this instead of a 14-50? * I don't drive much -- approx 150mi/week * It should be slightly more efficient (about 1/4 less time charging == less charger overhead) * On a...

With more AWD and P3D performance numbers hopefully coming in soon, and everyone hoping they are higher than quoted numbers, I remember hearing RWD acceleration numbers were cut back couple months ago. I'm ordering soon and finally decided on getting RWD for increased efficiency. So just...

We are building a home and plan to have solar in the future. We’re going with geothermal for heating and cooling so we can really take advantage of the solar, and hopefully fully power it from the sun. Of course, one of the most important factors with that is insulation. One of the geothermal...

Let us know what your average is, preferably since taking delivery. Also post what wheel tire setup you have. Here’s mine, although I think my later driving as been a lot more efficient (about 260) This is with 20inch 8.5 front 10 on the rear and pilot sport 4S

I wanted to know how my efficiency compares to others and what the distribution of efficiency look like among a relatively large sample of users. Screenshot is attached It turns out that distribution has the following properties: Most users get an efficiency of ~85-100% The most frequent...

My spouse and I made a trip from the Boston area to Philly and back last weekend for a wedding. We drove down on Thursday and back on Sunday. Thursday (June 1) was a lovely day, sunny, blue skies, temps in the low to mid 70s. Sunday started out overcast in Philly, a bit more humid, and...

So I love the kick you get when you slam the accelerator but then you get a depressing huge orange mountain in your consumption chart. I understand this mainly comes from pulling hard on batteries and Peukert's law. So why doesn't Tesla put in capacitor that could give max power for a few...

Hi folks, I am about to take delivery of my Model S (feels like I have been saying that for a year now, hurry up Tesla!!). Recently I came across a few threads and a video where folks pointed out peculiar problems with the heating and cooling effectiveness of Teslas. A number of folks say that...

Tesla factory 19" Aerodynamic Wheels (Aero Wheels) with Michelin Primacy tires Excellent Condition. Came with recently purchased Tesla CPO car. About 700 miles on tires, mostly from drive down from Tesla factory to So. Ca. Hoping for local sale/pickup (Huntington Beach, CA). My tire shop...

So, I'm noticing that Wh/mi is improved on side streets versus highway driving at 75-80 MPH. Having done that, I ran five trials on EVTripPlanner.com to see what the Wh/mi in a hypothetical drive, via mostly side streets, to cover a final 5 miles to some superchargers. My info averages to 215...

I created this thread to post and discuss our monthly driving stats. I brought this up in the TeslaFi thread, but all data loggers are welcome! I'll start with my August 2016: Driving stats Drives: 120 Miles driven: 1324.7 Time spent driving (hr:min): 46:49 (Wow, I spent 2 days driving)...

I've collected a small amount of data using teslafi.com and noticed that efficiency tanks as the ambient temperature rises. TeslaFi.com Tesla Model S X Data Logger Temperature Efficiency Temperature Wh/Mile Efficiency % Miles Recorded 60 to 70 F 365.27 87.1 13.79 70 to 80 F...

I follow this thread on the Model S sub-forum +10% Energy Efficiency after 2.24.102 Update There are several folks that have confirmed this on their S... after the update they see consistent energy consumption reduction! My X is on order, so to me it would be awesome to know that by the time I...

I'm thinking ahead to my Model 3 and pondering how I would replicate an essential ritual which has always been a part of car ownership in my family. Regardless of who fills up the car, my family has always kept impeccable records of our gas usage every time: Litres added Cost per litre Fill-up...

Since it's fun to speculate, I threw together a little python script that uses the EPA FTP-75/HWFET traces and the unadjusted EPA rating of the S 70D to guess at Model 3 range. Using an admittedly crude comparison, I'm guesstimating a 55kWh 3 will hit 240+ mile combined and 75kWh 3 will hit 325+...

How hard would it be to add a feature for the driver to be able to turn on and off the torque-sleep for the (I think) rear motor? By only using one of the motors, wouldn't that improve efficiency (but sacrifice performance)? I akin this to my wife's 2004 Jeep Wrangler. It's in 2WD all the...

MP/kWh seems a lot easier for me (most people?) to understand because it correlates well with MPGs. Thoughts?

One of the common, albeit misguided, criticisms of electric vehicles is that they get their electricity from coal, thus making them effectively more of a pollutant than a traditional ICE car. I seem to recall a video of either JB or Elon debunking that claim. If my memory serves me correctly...

Hello everyone that has a good understanding of electrical engineering. THE STRONGEST MAGNET IN THE WORLD - YouTube 5:36 Why is this technic not used as it would make the motor smaller and could have much more tight windings. My thought is not to have someone assembly this by hand, rather...

In an attempt to find the optimum driving speeds between superchargers for the minimum total charge + drive time, I did some number crunching. Using the Supercharger Table found here Tesla Model S - Supercharger Table for charge times and EVTripPlanner for rated miles used and drive times at...

With the the efficiency gains that the Dual motors has brought to the drivetrain, I was wondering, what else could Tesla do to improve eficiency? These are my guesses. Base range: 275 miles. + 5% by removing side-mirrors + 5% by installing regenerative suspension. + 5% by...

With the announcement of Solar City acquiring Silevo in part to jump start production of high efficiency solar panels, I thought it would be nice to have a thread that discusses what the differences are between common solar panels today vs the high efficiency panels of tomorrow. There may be...

I'm curious about the scaling of efficiency of a as you increase power, volume, and mass. I've been thinking about it since Elon mentioned a Tesla truck. Trucks tend to have a significant amount of mass, and when towing or carrying a heavy payload, the mass is increased even more. But with...

First: love the car - this is not intended to indicate it is anything but a game-changer (I posted compiled shipment numbers showing how game-changing here), the watt-hours-per-mile indicator in the car does NOT really tell you how much electricity you will need from your grid/solar connection...
