So just got a report from Japan that they're being throttled there as well: https://teslamotorsclub.com/tmc/posts/2778623/

So it's not ambient temperature related.

OFC it is not ambient based. Charging rate limit is set at the start of charging session. And it doesn't change during the session.
It is based solely on the hottest battery sensor reading.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW

Related, in the sense that ambient affects the battery temperature. Your link mentions that the throttling occurred at the second DCFC, but the important detail is that the first DCFC was a short one. Does that mean that summer range is initial SoC + a little more ? Without more battery temperature data we don't know more about the trigger(s). With summer upon us reports should come in a flood, but this all sounds like somewhere between bad and really bad, both for the effect on longer trip driving and the implications it has for battery degradation.

Has Nissan provided any information ?
