Tesla Semi has a modular battery pack, as revealed by the electronic parts catalog. This makes it easier to produce the truck in variants with different ranges.
Exactly a month has passed since the first deliveries of Tesla Semi, but we still do not know a lot of information about it. In particular, questions about its battery pack was of great interest, but detailed answers have not yet been received. However, a small nugget of information has been unearthed by @greentheonly/Twitter, who likes to dig into the manufacturer's car software codes.
This time @greentheonly looked at Tesla Semi's electronic parts catalog, which became available after the first deliveries took place. He found a lot of interesting information about Semi, which also included a picture of the truck's battery pack. It showed that Semi's battery pack is modular and consists of three subpacks, which can be a big advantage.
Some Semi porn for those that need it on this New Years eve.

The modular battery is rated at 1000V
DUs are cooled with "mega cooling" modules.
Axles are called: Torque and Efficiency.

A modular battery pack can be useful when the battery pack offers a very large capacity, which is true of Tesla Semi, and when the capacity is broken up into smaller parallel battery packs, there is no additional cost. When a manufacturer has multiple products in production, each with their own specific energy needs, such as vehicles with different ranges, they may use one module for a one car model and two or three modules for another one. For now, Tesla has introduced a 500-mile version of Semi that uses three subpacks. Obviously, when the 300-mile version is released, the manufacturer will use only two subpacks. This solution allows Tesla to purchase only one battery code per application, simplifying the supply chain, which is a definite plus.
