    I was at the Cranbury, New Jersey supercharging station on Sunday. My car (a 2017 90D) was down to about 25 miles left. There are 4 charging stations there and 3 were occupied, so I took the last one. After the car charged up to about 100 miles (just needed to ensure I got home with enough to juice to spare) - I unplugged and noticed how hot the entire charging unit was (and no, it wasn't due to the fact that it was 90+ degrees out on Sunday). The unit itself was extremely hot - is this normal??

    What is the "unit"? Plug and cord? It does get warm, but it should not get HOT. A poor connection as the Plug and charge port wears will cause increased heat.

    I've had a plug get quite hot when Supercharging a very low battery, in the sun, on a hot day. There's a lot of juice flowing through that port, heat is to be expected.

    Yes it is normal when all stalls are in use that the Supercharger gets warm. When you get near the fan of the Supercharger it feels like you are standing next to a giant hair dryer.

    Thanks everybody for the quick replies - just wanted to make sure that the heat from the plug was "normal"!!

    Oh by 'unit' you mean the plug. Yes that one gets pretty warm as well.

    ive actually touched a few plugs that if i held it more than 10 seconds im pretty sure i'd scald myself. but with the amount of juice that flows thru its to be expected.

    I've used it to stay warm the last minute or two of a charge at night in Colorado. I assume it was safe...

    If the handle geta super hot it basically mean either there is direct sunlight hitting it on a hot day or the connector needs to be replaced. Also you should be noticed slowed charging. If not then it must be one of those older supercharger.

    I suspect tesla will replace those handles that get hot even after the ramp down.

    I've encountered super hot handles in both sunny and dark conditions. I've also seen my charge kW get cut in half due to the hot handle regularly, regardless of the age of the charger.

    I was at Manteca SC once and noticed the charger quite hot warm even before I had plugged in. At the time it wasn't particularly busy or warm that day and I checked other chargers that were plugged in and they weren't as warm as the one I used. So it does happen and I believe there was an issue with that particular charger.
