Decoding Your Tesla Battery Pack Version

Identifying Your Tesla Battery Pack

Did you know the Tesla Model S battery comes in either an A, B, D, or E pack?

Your Tesla battery pack information is found on a sticker affixed to the front right side of the battery pack that can be seen when looking under your car from just behind the front right (passenger side) wheel.

The first and arguably the most important part of the label is the top portion which indicates the size of your battery pack. This is useful when validating that you received the correct battery ordered. The next piece of information which may have some potential value is the model of the battery indicated by the last letter trailing the part number. In my case I have the “D” battery pack.

Tesla Battery Pack Version

The main notable difference in features between battery pack versions occur between the A and B packs. An improvement to the cooling system of the battery pack was made starting with the B packs that allowed for faster Supercharging. Those with A battery packs can only Supercharge at a maximum of 90kW while those with B battery packs and later can Supercharge at 120kW, or possibly higher.

According to the TMC Wiki that tracks Tesla battery pack part numbers, the basic pack versions can be decoded through the following:

There’s a large variation of part numbers which may contain notable differences that the community has yet to identify. Or it may simply be an indicator for a refurbished pack versus a factory new one.

Barring formal confirmation from Tesla, the working theory is that battery pack versions A, B and D are equivalent to model years of the car. They’re evolutions of the same core battery pack with each subsequent letter being better than its predecessor. Superchargers capable of greater than 120kW are just starting to emerge. The 100th Supercharger, recently installed in NJ, was a 135kW Supercharger.

D battery packs began shipping sometime in the second half of 2013 and represent the latest versions to be installed. If you have a D pack rest assure that you’ve got the latest.

So far there have been no reported differences between the B battery pack and the D battery pack in terms of charge rates or performance, but the current theory is that the B pack may be limited to charging at 120kW while the D pack may be capable of supporting 150kW.

Summary

If you purchased a Model S in late 2013 or 2014, you’re most likely using the latest and greatest battery pack version from Tesla. However, if something should ever go wrong and you’re given a replacement battery pack by the Tesla Service Center, make sure you do not receive a refurbished A pack or any pack labeled with a version older than your existing one.

If you don’t know the version of your battery pack, do yourself a favor and go take a picture of it and save it for your records. You might be thankful you did one day.

Tesla pushes crazy ‘Luxe’ incentive package on flagship Model S and X

Tesla is pushing more customers to the Model S and Model X with a new incentive package.

Tesla has pushed a crazy new incentive package, known as the “Luxe Package,” on the flagship Model S and Model X, along with a $10,000 price increase on each trim level.

The move aims to likely bolster margins for the company on the two cars while also giving those who choose to buy the Tesla lineup mainstays a variety of awesome advantages, including Free Supercharging, Full Self-Driving, and other add-ons.

Tesla is offering a crazy Supercharging incentive on its two ‘sentimental’ vehicles

Last night, Tesla launched the “Luxe Package” for the Model S and Model X, which includes the following four add-ons:

  • Full Self-Driving (Supervised) – Your car will be able to drive itself almost anywhere with minimal driver intervention
  • Four-Year Premium Service – Wheel and Tire Protection, Windshield Protection, and Recommended Maintenance
  • Supercharging – Charge for free at 70,000+ Superchargers worldwide
  • Premium Connectivity – Listen to music, stream movies, monitor live traffic, and more – no Wi-Fi needed

Full Self-Driving is priced at $8,000. Free Supercharging for the life of the car is between $10,000 and $15,000 over the life of the vehicle, although Tesla has valued it at $5,000 in recent promotions.

Free Premium Connectivity is roughly $1,000, and the four-year tire, wheel, windshield, and maintenance plan is about $3,200.

In all, the value is over $25,000, but this is loosely based on usage.

The Model S and Model X are low contributors to Tesla’s overall sales figures, as they make up less than five percent of sales from a quarterly perspective and have for some time.

As they are certainly the luxury choices in Tesla’s lineup, the Model 3 and Model Y are the bigger focus for the company, as a significantly larger portion of the company’s sales is made up of those vehicles.

The Luxe Package is an especially good idea for those who drive high-mileage and plan to use the Model S or Model X for commuting or long drives. The free Supercharging makes the deal worth it on its own.

As for the price bumps, each of the vehicles are now priced as follows:

  • Model S All-Wheel-Drive: $94,990
  • Model S Plaid: $109,990
  • Model X All-Wheel-Drive: $99,990
  • Model X Plaid: $114,990

Tesla takes first step in sunsetting Model S and X with drastic move

Tesla won’t be taking custom orders of the Model S or Model X in Europe any longer.

Tesla has seemingly taken the first step in sunsetting two of its older vehicles, the Model S and Model X, by ending international orders.

The flagship sedan and SUV from Tesla are the two oldest cars in the company’s lineup. They account for a very small portion of overall sales, and several years ago, CEO Elon Musk admitted that Tesla only continues to build and sell them due to “sentimental reasons.”

Earlier this year, there were calls for Tesla to end the production of the two cars, but Lars Moravy said that the Model S and Model X were due to get some love later in 2025. That happened, but the changes were extremely minor.

Tesla launches new Model S and Model X, and the changes are slim

Some took this as an indication that Tesla has kind of moved on from the Model S and Model X. A handful of people seemed to think Tesla would overhaul the vehicles substantially, but the changes were extremely minor and included only a few real adjustments.

In Europe, customers are unable to even put a new order in on a Model S or Model X.

We noticed earlier today that Tesla pressing the ‘Order’ button on either of the flagship vehicles takes you to local inventory, and not the Design Studio where you’d configure your custom build:

Tesla simply does not make enough Model S or Model X units to justify the expensive logistics process of shipping custom orders overseas. It almost seems as if they’re that they will essentially build a bunch of random configurations, send them overseas every few months, and let them sell before replenishing inventory.

Inversely, it could also mean Tesla is truly gearing up to sunset the vehicle altogether. It seems unlikely that the company will fade them out altogether in the next couple of years, but it could absolutely think about ending international orders because volume is so low.

Tesla confirms massive hardware change for autonomy improvement

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla first introduced a front-facing camera on the front bumper with the Cybertruck.

Then, the Model Y “Juniper” received the hardware update. The Model S and Model X both received the front-facing camera with its latest update, which was officially revealed last week.

Tesla used new language with the release of the front-facing cameras on the Model S and Model X, confirming they will assist with several things, including “using Autopilot and Actually Smart Summon capabilities”:

“Enhanced visibility when parking or using Autopilot and Actually Smart Summon capabilities.”

This tiny feature on the new Tesla Model Y is perhaps its biggest addition

This is the first time Tesla has used this sort of language, as it was a completely different description with the launch of the new Model Y in January.

When Tesla launched this vehicle, it said the front bumper camera “provides a wider field of view for automatic assisted driving and advanced Smart Summon.”

Tesla switched from using cameras and sensors to only cameras with the launch of Tesla Vision several years ago. The company’s utilization of cameras comes from Tesla’s belief that Ultrasonic Sensors (USS) are not needed for self-driving efforts:

“Along with the removal of USS, we simultaneously launched our vision-based occupancy network – currently used in Full Self-Driving (FSD) (Supervised) – to replace the inputs generated by USS. With today’s software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.”

CEO Elon Musk has said that sensors were only a crutch and that self-driving would be solved through the use of cameras:

“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”
