A Tesla hacker who goes on Twitter by the identify of “inexperienced” has shared a bunch of Tesla Semi diagrams on the social media platform. Once I requested him how he obtained these photos, he stated he acquired them from the automaker’s on-line elements catalog web site, aka EPC.
So, I logged into my Tesla account and regarded for the Tesla Semi elements catalog, nevertheless it was not on the checklist. Apparently, moral hacker “inexperienced” acquired these photographs even earlier than the Tesla Semi catalog was printed by digging deep into the web site. These Tesla Semi diagrams and a pattern VIN label are attention-grabbing to have a look at, particularly for these planning to purchase considered one of these class-8 electrical vehicles sooner or later.
Tesla Semi Battery Pack
For the reason that Tesla Semi was unveiled in 2017, the placement of the battery pack, its form, and the capability (in kWh) have been stored a secret by Tesla — however a diagram from these leaked pictures opens up a few of this data to us (see diagram 1.1 under).

As we will see within the above diagram, the massive battery pack is situated beneath the Tesla Semi cabin. The battery pack of the Tesla Semi consists of 9 modules which can be formed like sq. blocks. Three blocks within the mid-row appear to be bigger in comparison with those on the aspect rows.
Unexpectedly, Tesla designed the battery pack of the Tesla Semi truck fairly otherwise from those we’ve seen in different Teslas, just like the Mannequin Y and Mannequin 3, and many others.
The division of those modules into totally different blocks could be a sign of a replaceable battery module, as these vehicles can be accumulating a lot of miles of their lifespans. However this has but to be formally confirmed by Tesla (TSLA).
Braking, Suspension, and Excessive Voltage (HV) Methods
The diagrams highlighting the braking techniques and suspension elements are additionally fascinating to have a look at.
Since these diagrams usually are not labeled with particulars, the knowledge is scarce proper now. We might want to anticipate the automaker’s official Tesla Semi elements catalog to be printed. As a result of Tesla began Semi truck deliveries on December 1st, 2022, the elements catalog would possibly get on-line very quickly.

Tesla VIN Label
Together with the above technical diagrams of the Tesla Semi truck, a pattern VIN label was additionally found by Mr. inexperienced. This label has some details about the Tesla Semi’s gross automobile weight ranking (GVWR) and the way a lot every of this weight every axle is ready to bear.
The 22,135 kg (48,800 lb) of GVWR talked about on this label is only for the bobtail Tesla Semi (with out the trailer). When the trailer is hooked up to the truck, one other set of axles is mechanically hooked up to the trailer’s rear wheels, so including that brings the entire GVWR to ~37,200 kg (82,000 lb).
This label additionally consists of Tesla Semi wheel and tire sizes and different respective chilly tire stress rankings as nicely. Nevertheless, for an official affirmation of those numbers, we should anticipate the Tesla Semi proprietor’s handbook.
| Axle | GVWR | Tires | Rims | Chilly Tire Stress |
|---|---|---|---|---|
| Entrance Axle | 5,715 kg (12,600 lb) | 275/80R22.5 | 22.5X8.25 | 310kPa, 45psi |
| Int Axle | 8,210 kg (18,100 lb) | 275/80R22.5 | 22.5X8.25 | 310kPa, 45psi |
| Rear Axle | 8,210 kg (18,100 lb) | 275/80R22.5 | 22.5X8.25 | 310kPa, 45psi |
