Some interesting results.

The results were expected if they had done some homework.

Yah a rookie mistake for sure but its part of the learning process.

We carry a campground charging kit with 4 dongles for the EVSE that came with the car.

5-15 which allows charging at 12 amps at 120 volts
5-20 which allows charging at 16 amps at 120 volts
TT30 which allows charging at 24 amps at 120 volts
14-50 which allows charging at 32 amps at 240 volts

But these are "intelligent" dongles with a little circuit that tells the EVSE the max it can draw from any given circuit. This prevents breaker tripping.

In addition it has a temperature sensor in the plug in end. If it detects high temperature caused by a bad connection on the receptacle it will limit the current to either 75 percent or 50 percent or shut it right off. It also does this if it detects low supply voltage. Nice.

By far our most used dongle is the TT30 as we rarely rent 50 amp sites.

Here is our kit. The EVSE and 5-15 came with the car, we bought the other three dongles. There are 9 available in all so you can pretty much plug into anything, welders, dryer outlets etc, but these are the only ones we use.



We are using the TT30 at this site.
