Charging Help!

[Sideline]

Yes indeed. I just showed the electrician the 14-50 plug and off he went. I actually have two of these in my garage …long story but I have two EVs but I only charge one at a time although I suppose I could as they are on separate circuits.

That Leviton outlet is not designed for the service duty of EV charging. You can see the overheating (or possibly arcing) on one of the phases. Considering changing to a Hubbell HBL9450A Straight Blade Devices, Receptacles, RTP, Industrial Grade, 3-Pole 4-Wire Grounding, 50A 125/250V, 14-50R, Black, Single Pack. | HBL9450A | Hubbell Wiring Device-Kellems

agreed

most NEMA sockets are not designed for hte thermal load day-in/day-out for multi-hour sessions at a full 9.6 kW with no "downtime"

you want a Hubble industrical grade socket…

the plug in the picture already shows signs of thermal stress and overtime may lead to thermal stress induced failure…

as NOTED/Required by Porsche - it will handle the load no sweat…

That was my first one. I can check into it but never had an issue since 2018 in use. The new one for my Porsche is a different brand

who's EVSE were you using in 2018 - Porsche's EVSE's have a high nominal operating temperature (higher than other EVSE brands I've used) and therefore are more stressful on NEMA sockets…

with the Porsche EVSE you really want the best NEMA sockets possible given it's normal operating behavior.

Got it to charge my 2018 Nissan Leaf and now use it for my Volvo XC40 with no issues

who's EVSE - also Leaf EVSE is not a full 40 amps…

Thanks all! Great info. Love this forum.

How do you all feel about battery safety...(might be a different thread but....)?
I'm keeping mine outside all of the time, not just when charging. The chance of the battery melting down is pretty low, but not zero and if it does, I don't want to lose my house. I'm keeping my 3 other cars inside...my mini-collection ('07 997S manual, '06 Cayenne manual and my 1990 VW Vanagon. The Macan is my entry into modern times. Love it so far!

Correct I only charged at 38 amps as far as I recall. It had a small battery but charged up over night which was fine

yeah battery worry is overdone…

Hum...ok so now you have me thinking a bit on this. I thought that all industrial NEMA 14-50R were built to meet the same standard but this looks like that may not be the case. Although I have had no issues that does not mean I might not have them. Thanks I put a call into my electrician if need be I will swap it out.

Note that the one shown is not used for my Porsche but the brand new one is not marked with a manufacture ID so that is what I will look into.
