Ah, finally, an area where I am an expert. :)
The communication is defined in ISO 15118-2, the transport layers are in
15118-3 (PLC) and 15118-8 (wifi). No one is using the wifi version for
DC - only for wireless power.
However, nowhere in the spec does the battery temp get sent. There is a
warning when the battery is over temp, but that's about it.
Most of the time, the job of protecting the battery is the BMS. The BMS
tells the EV-side charger how much power it can accept, and when to
throttle power.
Part of this is that the OEMs think that any info about the battery is
confidential information. Which is why SoC is optional, and not always
sent to the charger.
And yes, you are absolutely correct, Peri: you DON'T want to read these
specs... they are a very good cure for insomnia.
Cheers, Peter

DC fast chargers use HCL defined in ISO 15118-8 Specification.
Volume eight is the physical and data link layer

I thought the level 3 chargers took into account cell temperature
and other conditions. I know, for example, that my almost 10 year
old Leaf battery charges at only about 10kw now. Something is
communicating.
