Jay Leno video on the Semi

If the battery is in the 800-1000V range, do you think it's like 850 nominal? Always seemed weird to me to want to go to 1000V nominal as in most cases it would require you to make your electronics capable of a higher voltage level which would be expensive and much less established just to be a hair over the threshold. Current generation electronics for CEVs have a 1250V max voltage and you want some buffer. If you go over the threshold, might as well go to 1500V I suppose its good marketing to use max voltage versus the common nominal voltage so it sounds cooler!

Since we heard in the video that Semi and CT are sharing inverters, the two vehicles should have similar nominal voltage.
This gives us another clue. NACS is being standardized at 1000V rating.
<1000V at full charge. Your guess of 850 nominal seems to be in the right ballpark then.

Yah, they also said that in the Leno video at the 28 minute mark.
