In addition to battery cooling fluids there are others.
Did a lookup, found interesting tidbit on tesla transmission fluids.

"The Tesla Model S requires different amounts depending on what drive units are in the vehicle. The car needs:
- About 1.5 quarts (1.4 liters) on the rear large drive unit.
- 2.4 quarts (2.25 liters) on the rear small drive unit.
- 1.8 quarts (1.75 liters) on the front small drive unit.
For Tesla Model S drivers, especially for models from 2012 to 2016, the fluid has to be switched out once after 12,500 miles (estimated for 1 year) and then again in years 5 and 9. We will cover more about the
servicing of Tesla transmission and gearbox fluid further below. It starts to get very interesting when you move onto the more modern units and other Tesla models and their gearbox fluid."
"The above-mentioned guidance on the first change coming after 12,500 miles and then after years 5 and 9 has since been removed from later models and it’s now considered to be “maintenance free,” but the fact is that they may still need changing after 100,000 to 150,000 miles."
