Went from a ford cmax energi, I can't remember the max charge rate, to a 2020 bolt and I'm using the same ~2 year old aftermarket 220/240 32amp aftermarket charging cable. I had a nema 14-50 plug added to my garage, 6 gauge wire, 50 amp fuse, 12 inch from the bottom of my electric box permitted and inspected. No issues charging the cmax, cable did not get hot at all. Just chargd my Bolt from 15%-100%, lets say 8 hours of charging, was charging at the full 32amps per the display on the charger. Now the head of the plug gets pretty damn hot. It was 75F in my garage and the temp gauge on the display of my charger got up to 125F. I'm trying to determine if this is "normal" or "expected". The manufacturer says its normal up to 150F and they test up to 180F. Seems pretty hot to me. Outlet is cool, its the plug head and the first 18 inches of the cable is pretty warm, rest of the cable is barely warm. No sign of melting, no bad smell, pulled out the plug and the 4 pins, while hot, are clean, no plastic etc.
