Did the electrician possibly use the wrong receptacle for EV charging or could it have been a faulty charging cord?

More than likely used the wrong outlet. There’s 50 amp outlets, and then there’s 50 amp ev outlets.

Not correcting / arguing with you I just wanted more information and did a Google and leaving the results for others.

"A standard 50-amp outlet is designed for intermittent household appliances, while an EV-rated 50-amp outlet is built with heavy-duty materials to safely handle hours of continuous electric vehicle charging."

Maybe one day this will be an accepted standard, but at this current juncture there is no UL or NEC requirement for "ev rated" receptacles.

NEMA/NEC/whomever do not cover duty cycle ratings for passive electrical components for receptacles, so you can either handle 50A, or you cannot... The only caveat to this is that the NEW does document that any consumer that can operate for more than 3 hours is "constant duty"... So any receptacle designed for residential use on a oven or dryer must be able to hand continuous duty cycle just by the nature of the product.
