NOTE: this cable from Amazon - routinely achieves operating temperatures of 87-93F in normal multi-hour operation at 9.6 kW (or more) vs. Porsche's supply cable temps of 144F (or more)…the cable listed below has 6 gauge wire for the high voltage 120V legs (red & black wires), and 8 gauge wire for the unused neutral and ground (white & green wires)

93F vs. 144F is pretty damming in terms of where the problem lies - the 93F operating temperature of the $30 cable from amazon will place less accumulated thermal stress on cheaper Leviton NEMA 14-50 sockets - meaning there is less chance the EV charger will induce thermal failure (melted plastic).

we all know what the core problem here is - it's unclear to me why Porsche is not stepping up and distributing replacement power supply cables with an wire gauge that matches their _OWN_ recommendation from the NTSB bulletin - where they require/recommend/demand 6 gauge wire for these types of electrical loads.

In Porsche's OWN tech advisory they recommend the use of 6 gauge wire for 50 amp circuits - but they ship their supply cable with 10 gauge wire…hmmm.

the socket manufactures it's own thermal stress in defiance of the laws of thermodynamics/conservation-of-energy - it's not that Porsche's NEMA male-plug is getting too hot due to trying to shove 9.6 kW of power into a 6 kW wire and then subsequently transferring the massive amounts of heat due to electrical resistance - the plug itself is generating the heat - and in fact might be a power source more powerful than home solar panels…

the type of damage caused in this thread…

https://www.taycanforum.com/forum/threads/porsche-mobile-charger-recall.14275/#post-214742

totally 100% th plugs fault - it's self destructing because it can't handle the power/performance of the Taycan - this is not the result of accumulated thermal stress of a poorly designed power supply cable that routinely achieves operating temperatures of 140F (or more) in normal use and overtime causes cheaper Leviton plug sockets to eventual fail when their cheaper plastics subjected to repeated thermal stress causes a structural failure…induced by unnecessary thermal stress.

the plug below self destructed and lost it's will to live because it couldn't handle the awesome power of the Taycan!!!

totally 100% not Porsche's fault that their cable routine achieves operating temperatures of 140F+ in normal operation…

You forgot one more picture

Apparently the photos showing temperature readings of the outlet, plug, and cables that you and others posted in here a couple years ago were EVSE "disinfo"......

Finally! Somebody found me out! As I recall, I posted many photos of the temps generated using the PMCC and even supplied them to PCNA. They were non-plussed. If one is interested, go dig up the PET for the 918 Spyder. I think you might find some interesting similarities in parts between the 918 and the Taycan.

The temperature readings, photos, and posts about PMCC in the forum provided me the info I needed in summer/fall 2021 to avoid including it before my order locked.
Thank you.

If I buy the Porsche Wall Charger Connect as suggested in an advertising email I received from Porsche and have it installed by a licensed electrician I select – not Qmerit, what is the Porsche warranty for the device?

Thank you for contacting Porsche Cars North America about your wall charger warranty.

Your Porsche Wall Charger will still have a warranty of 2 years if it is installed by a different electrician (non Qmerit/Porsche). To view more information about warranties and Porsche parts, please click here.

I cannot help but notice that according to this reply the warranty only applies if you install through a Porsche authorized installer, so essentially no warranty if you have your own electrician or install it yourself. Yet another reason not to buy Porsche EVSE - not only expensive to buy, but also expensive to install if you want warranty.

Good catch. I edited my post above to highlight that point.

I asked PCNA about warranty for PWCC if not installed by Porsche authorized installer. PCNA reply is included in my post above. (edited).

PMCC 'thermal event' report :

https://www.nhtsa.gov/vehicle/2021/PORSCHE/TAYCAN#complaints

 

[Jonathan S.]

Is that what Maui recently experienced, a euphemistically termed "thermal event"?

 

[daveo4EV]

I've been thinking more about this - big surprise I know - we all know we have issues with the PMC+/PMCC - but the word "mobile" is part of the actual product _NAME_ and also indicates it's purpose - it's supposed to be a _MOBILE_ charger - which means you can use it anywhere under a variety of circumstances…

now we also know that Porsche has strongly recommended/required a high quality Hubble NEMA socket due to the PMC+/PMCC's high nominal operating temperatures - that strong-suggestion/requirement is documented here…

now this recommendation/requirement is fine for home - but does Porsche honestly expect me to only use their MOBILE charger at NEMA sockets that are hubble's - when you are traveling around you take what you can get - and most places with NEMA sockets are NOT going to be high-quality hubble sockets - they are going to be run of the mill crappy, old, and quite frankly dilapidated NEMA sockets that have seen better days…

basically given Porsche's psuedo-requirement for a Hubble socket in your home - they are admitting their "moible" EVSE isn't really all that "mobile" because they have acknowledged that due to very high nominal operating temperatures it should not be used with "lesser" lower quality NEMA sockets - you know the majority of NEMA sockets you'll encounter when you are away from home and want to use your "mobile" EVSE - but don't use it unless it's a NEMA Hubble socket, because it might melt…

so it's a Mobile charger that isn't really all that mobile if you want to not melt your host's NEMA socket while traveling away from home…

so it overheats in normal usage at home but you need a Hubble ceramic socket to - and probably you shouldn't use it while traveling because the range of quality of NEMA sockets you'll encounter in the wild are likely to be toward the lower range of quality on average…and it's the most expensive EVSE money can buy…

post #4 from this thread inspired this particular "insight" today - https://www.taycanforum.com/forum/threads/porsche-taycan-portable-mobile-charger.7118/#post-269784

the Porsche Moblie Charger+ (PMC+) and/or Porsche Mobile Charger Connect (PMCC) - not really all that mobile if you think it about if you want to use it safely.
