That's all kinda scary (and scares me away from it, a bit, tbh), hearing this about it being "locked at" any specific kW value. kW isn't what limits an adapter - it's amps - and I'm worried about how they're speaking in kW terms instead of amps. Something fishy going on here. (sure, kW and amps are closely related within the same vehicle - but any designer/engineer tinkering with the design ought to be inclined to talk about amps, not watts)
Given their mechanism, perhaps, of breaking the CP line based on a thermal cutoff, that would mean it would stop charging with a fault if it overheats - it wouldn't just slow it down.
The CCS handle and the Tesla's charge port both have temperature sensors right at the tips - so I don't really think such sensing is necessary - but, hey, it may as well be there, if they've got the space. Just doesn't inspire confidence.
I'd worry that the kW limit was a result of thermal throttling on the car or station side... when they heat up, they don't "work at full speed or not work at all", they'll slow down first. Hmm...
