Tesla Model S Survey Form

Tesla Model S

The purpose of this survey is to allow Tesla Model S owners to share their experience with battery pack capacity and how it changes over time and distance driven. If you are a Model S owner, please contribute your experience to the survey by filling in the information below. You are welcome to enter data again as you increase your time and distance.

If you have previously entered a report on this vehicle, use the Model S Battery Survey Update Report

Before you start, you may want to collect several bits of information from your car.

  • Current odometer reading
  • VIN sequence number (see the VIN sticker or tap the Tesla logo at top of the touch screen)
  • Assembly date (VIN sticker, see photos below)
  • Firmware version (tap the Tesla logo at the top of the screen)
  • Battery pack part number (see instructions below)
  • Rated Miles/Km after a full Daily and/or Trip mode charge (you'll need at least one of these numbers)
  • Energy and distance from longest-running trip meter

Measuring Battery Capacity

To get the most accurate reading of your battery capacity, you should read the "Rated Range" (not Projected Range or Ideal Range) from the charge state screen shortly after unplugging. If it's not convenient to get the reading at the best possible time, enter whatever you can read from the closest time.

Your Model S

Model S VIN Sticker Location
With the driver's door open, the VIN sticker is visible on the body frame in the bottom right corner.
Model S VIN Sticker Detail
The VIN is printed at the bottom of the sticker and the manufactured month/year is in the upper left corner.



VIN Sequence Number (last 5 or 6 digits, no letters): (kept private)
For the example in the image on the right, the VIN sequence number is 1237. This portion of the VIN is required in order to properly identify vehicles and follow-up reports for the same vehicle. It will only be used internally for the survey and will not be disclosed in any reports.

Manufactured Date:  
To get the assembly date, open the driver's door, there is a sticker at the bottom right of the door opening. On the top left of that sticker is the build month and year, eg 09/12 for September, 2012. Estimate this if the manufacture date isn't shown on your VIN sticker, e.g., vehicles delivered in Norway.

When did you take delivery? (mm/dd/yyyy)

What was the status of your Model S when you acquired it?

Onboard Charger Type

Supercharger Enabled

Wheel Size
If you're not sure of your wheel size, you can read it from the sidewalls of your tires. In the tire size it's the number after the R. So if your tire size is 245/45R19 you have 19" wheels and if you have 245/35R21 tires then your wheel size is 21".
If you have a custom wheel size, please note it in the comments.

What is your Model S ownership status?

Odometer at delivery: miles

Current Odometer: miles

Firmware version: e.g., 4.4(1.31.11)
To get the firmware version, tap the Tesla logo at the top of the touchscreen.

To find the battery pack part number, turn the steering wheel all the way to the left, then look behind the front passenger side tire to see the sticker on the battery pack. An example sticker is shown below with the part number highlighted.

Your battery pack part number: (optional, should look like: XXXXXXX-XX-X)

Major Drivetrain Components

Has your Model S's battery pack been replaced?
Note: For the purpose of this question, we don't count temporary swaps that represent less than 10% of your driving (e.g. at the Harris Ranch battery swapping station). If you've done temporary battery swaps that account for more than 10% of your driving, please make a note of that in the comments field below.

Have either or both of your Model S onboard chargers been replaced?

Has your Model S's drive unit been replaced?


To set the range display mode to Rated, tap on the Control button at the lower left corner of the touchscreen, then tap "Display" and scroll down to the "Energy Display" setting which should be set to "Rated", as shown below.
range display setting

Notes: If you see a range of values, please enter the average or most common value. If you don't know a value, please leave it blank or wait until you've made a reading to submit. If you haven't done a full 100% Trip mode charge recently, next time you do, you can use the update form to add the 100% charge number to your report. You will need to enter at least one of the range numbers to complete the survey.

Even if you prefer to use Ideal miles for your range display, please use Rated miles for the range questions below. We need everyone to use the same units so we can compare values. The image on the right shows how to set the range display mode to Rated for the survey.

If you've done a full 100% Trip charge, please enter your rated range:
Full 100% Trip Mode: rated miles

If you don't normally charge to 100%, and few owners do, please enter your charge target and rated range:
Typical Charge: % (each tick mark on the display is 10%, estimate if between ticks)
Typical Charge: rated miles

How do you most often charge? Volts Amps

How often do you charge in Standard Mode?

How often do you charge to 100%?

Are there any Tesla Superchargers within your driving range?

How often do you use a Supercharger?

If you've had a opportunity to determine your maximum charge rate at a full power Supercharger station, please enter it: kW


How do you use your Model S?

How often do you drive your Model S?

What is your typical daily round-trip distance? miles.

About what portion of your miles are driven on freeways or highways? %.

If you have one of the trip meters with a significant number of miles (perhaps your "B" trip meter has your full driving history), please enter your miles and energy use below.

Trip distance: miles
Trip Energy: kWh and/or Wh/mi
