Elon Musk the fraudster, page-26

What these brainiacs have failed to acknowledge is that the megachargers are going to incorporate very large battery packs in order to not upset the grid .

Bit like the SA Tesla battery did the other day when Loy Yang lost a unit .

He has already stated that they are likely to use large solar and other renewable sources to charge these batteries . So they would be additional to the generation that is available now .

While he hasn't provided all the details which the journalist appears to have an issue with , why would he ? His record so far suggests that he will get this done .

As to how quickly the truck batteries can be charged ? There are practical limits to how much energy you can deliver in a short time however people seem to have forgotten that Tesla has previously experimented with change out batteries with their cars . I wouldn't be surprised at all that they have an automated battery changeout station that swaps the truck battery in a few minutes .
Given how Tesla uses technology for their charging network now it if feasible to assume that their trucks will communicate with their megacharger network so that they know they have the charging capacity ( or a changeover battery ) available and will be able to secure it before the vehicle getts there .

Also , these Tesla trucks are initially designed for shorter haul duty so it is quite likely they will charge overnight while they are parked , thus limiting the load for quick charging .

Funny how the selective quote has mentioned none of this ?
