Indeed, Nyland is an absolute gold mine for this stuff. And indeed: 800V CCS cars tend to beat Teslas by 10-20% overall at time-on-the-charger. It's a good architecture, if not a huge deal (it also pays benefits with lighter and cheaper cabling at the charger). Swapping pack voltage is somewhat of a compatibility hassle, but I'd expect Tesla to try to follow this at some point in the coming years.
