TESLA CYBERTRUCK and Battery Pack

Update: Now that Tesla Cybertruck has been launched and first delveries/bookings being confirmed. We can update the article and benchmarking based on the data available from the websites and various forums. We are now seeing them on the road and buzz is going around with various video reviews. Recent Q2 Earnings call gave us the term “Cybercell” aka 4680 Gen 2. In this article we will try to calculate the new 4680 Gen 2 Battery energy and what various Tesla Cybertruck Models battery pack sizes will be based on the data available and the calculators from this site.

Tesla CYBERCELL aka 4680 Gen 2

As announced in 2020 Battery day the 4680 which has been in production at Tesla Texas gigafactory will be used in the Tesla Cybertruck. Youtube Video Link Tesla Battery Day 2020. Tesla produced the 20th Million cell recently at this site.

We have a detailed Benchmarking and analysis on Tesla 4680 on our Battery design website which is based on Limiting Factor Teardown. Based on Benchmarking below is the data for Tesla Gen 1 4680.

Cybertruck Cell “Cybercell” will be launching with Gen 2 4680 cells will have 10% Higher Cell Density. Tesla Gigafactory produced 20 Millionth 4680 in Oct 11 2023. Source: Tesla Earnings call Q2 2023. Start listening around 18th Minute for above statement reference to Cybercell.

  • Nominal Voltage: 3.7V
  • Capacity: 23.35Ah x 1.1 = 25.685Ah at 2.5A discharge ~C/10
  • Nominal Energy ~95 Wh
  • Mass: 0.355kg
  • Cell gravimetric energy density = 268 Wh/kg

Cybertruck Models

  1. Single Motor Rear Wheel Drive (RWD): 250 Miles or 402 km (2025 Launch Date)
  2. Dual Motor All Wheel Drive (AWD): 340 Miles or 547 km (more like +350 Miles or +560 km based on Tesla Model 3 Long Range AWD). Range Extender – 470Miles
  3. Cyberbeast AKA Tri Motor All Wheel Drive (AWD): 320 Miles or 515 km (surprisingly not 500 miles but with range extender +440 Miles)

Calculating Wh/km

We need various parameters to calculate Wh/km. I will use BatteryDesign.net calculator for this purpose. Link for the calculator (thanks Nigel).

  1. Vehicle Mass – 7000 Pounds (various sources says Tesla will have weight somewhere 7000 Pounds (3175 kg) but recent Munro Video says Tesla might be trying to reduce weight to reach under 6001 Pounds (2721 kg). This is to do with Tax purposes if vehicle mass (GVWR) is higher than 6001 Pounds and lower than 10000 Pounds then its classified as Light Duty truck. This maybe possible with Tesla Unibody construction with structural battery pack.)
    • Update 3rd Dec. AWD – 6603 LBS, Cyberbeast – 6843 (without Range extenders)
  2. Vehicle Speed – 100 km/h
  3. Cd Coefficient of Drag – 0.34
  4. Frontal area -3.372m2
  5. Coefficient of Rolling Resistance – 0.0196

For Cd and Frontal Area I found this great analysis by Wouter Remmerie. They had done in the past on design analysis using Airshaper to show calculate Cd of 0.43 but this post on LinkedIn explains the potential changes/improvements Tesla might have done to bring the Cd down from 0.43 to 0.34.

The calculator has the default values of the CyberTruck entered and this then gives you the ability to modify the values and immediately see the impact on power demand and energy use:

Based on this we arrive at 314 Wh/km.

Calculating Battery Pack size and Configuration

  • Single Motor will be released later in 2025. Specs still not confirmed.
  • Dual Motor AWD: Range Estimated by Tesla (340 Miles) 547 km x 314 Wh/km divide by 1.25 (25% regeneration) = 129 kWh
  • Tri Motor AWD: Range Estimated by Tesla (320 Miles) 515 km x 314 Wh/km divide by 1.25 (25% regeneration) = 121 kWh

Going by Model 3 which uses 4680 based on our benchmarking article link uses 828 cells in 92 s 9 p configuration.

This Pack Sizing tool is a simple to use online calculator that allows you to modify values and instantly see the results.

Battery Pack Benchmarking and Conclusion – Vehicle Architecture, Configuration etc

In the Q3 2023 Earnings call Tesla Mentioned “For very heavy vehicles, a high voltage powertrain architecture brings notable cost savings, which is why Cybertruck will adopt an 800-volt architecture.”

We now know that the battery is 192s 7p and that means the 816V refers to the maximum charge voltage of 4.25V per cell. 150Ah with 7p means 21.4Ah for each cell. This feels like the EPA filing might have been an earlier pack design. However, some of these EPA filings are very ambiguous.

Based on many articles we can see that Tesla has a 123kWh battery pack and it also looks like the Same battery pack is used for both Dual Motor AWD and Tri Motor AWD. This matches roughly with the Calculations we have arrived upon too (129 kWh for Dual Motor and 121 kWh for Tri motor).

  1. First teardown video of the pack: https://www.youtube.com/watch?v=ipe5A4ZN3Gc
    Battery configuration: likely (but not yet completely confirmed) 192s 7p, which would be about 705V DC nominal. 4 modules of 336 cells each. The 4 modules are 48s 7p each. To be confirmed once they can look under the green foam which may hide a couple of more cells at the ends.
    There should also be a switching circuit that can either switch the pack to 192s 7p (all 4 modules in series) or 96s 14p (2s2p of the modules).
