Strange Temperature spikes?

I am seeing these odd temperature spikes when I charge my 2024 Lyriq. Max current is 50A. Ambient temp is around 32C. Any thoughts or ideas?

Temperature throttoling reduces current if temperature in the enclosure exceeds 65C.  30C rise at 48A seems about right but it may not be a bad idea to check that all wire connections to the relay are tight. Excess heat is almost always from a loose connection.


Here is an article on the subject.

Thanks for the tip. I did check all connections and things are looking good. Mostly I am happy to know that this delta temp is not unexpected. I will carry on.
