Hello,
my Taycan has been charging at 40 amps for over 2 hours this morning at roughly 64 degrees ambient temperature. I gathered the following data from various points in the charging circuit:
all measurements are on Fahrenheit:
I think the NEMA 14-50 cable is getting too hot - probably due to inappropriate wire gauge - the label says rated for 16 amps - and thickness is appropriate for 16 amps - I'm betting they didn't do the proper gauge for North America, and instead are working European standards - 3 phase 16 amp rated wire - but what do I know.
the supply Cable from the sub-panel is less than 90F - and the breaker itself is less than 90F - but the Porsche provided supply cable is running 2x temp vs. the rest of the system - something seems wrong.
the temperature of the J-1772 cable and the J-1772 Plug are below 90F - so no issues there.
