2 nd Tesla Recall, page-12

Have a look at John Cadogan's channel on YouTube.

He has a recent video about the battery size, capability and economics of the Tesla semi.

While part of his video is really a couple of educated guesses, he does approach the subject on a factual basis .

Cadogan is definitely an acquired taste for some ( ahem ) , but he always backs his views with hard data and good engineering principles.

Worth a watch if you've got the time.
