Careless EV drivers can also break the public chargers they need by abusing the J1772 and cable. For example, a new, free, dual, 80A, L2 charger lost one side due to a "diode error." This is a Tesla class, EVSE. But it had been installed without J1772 holsters to keep them off the ground and out of the rain. They were soon found but now one side now reports, "DIODE ERROR." So I bought the most recent copy of SAE standard, "SURFACE VEHICLE STANDARD J1772™ OCT2017." Bob Wilson
I cringe when I see this and have also seen public charging locations showing the error in one form or another. It certainly makes me a lot more cautious if I need to use one and see that someone didn't bother to plug back into the holster.
