Extra 7PP.971.678.xx power cord for PMC+

[fgwinn]

I ordered my Taycan CT with a NEMA 6-50 power cord for the PMC+ EVSE. I am planning to visit some friends and family with a NEMA 14-50 outlet in their garages. The various power cords all seem to have the same part number except for the two character suffix. The part number for the 6-50 cable is 7PP.971.678.EC.

DelawarePorscheParts.com lists the various cords for $110.78 but the descriptions do not specify the NEMA plug type and there are no images for the listings.

I am hoping that someone could snap a photo of the label on the NEMA 14-50 version of the power cord and post it to this thread.

Just get this from amazon - $23.99 - Porsche charges way way way too much for the Supply cables

_OR_

you can purchase any ENTIRE EVSE with a 14-50 plug for less money than the Porsche supply cable ordered as a separate part.

https://smile.amazon.com/Oviitech-14-50P-Adapter-Generator-Converter/dp/B08QVKHT1F/ref=sr_1_5?crid=RTB14J5VNX1U&keywords=nema+14-50+to+6-50+adapter&qid=1663770857&sprefix=nema+14-50+to+6-50,aps,139&sr=8-5

there is NO issue converting one type of NEMA 50 amp plug to another type of NEMA 50 amp plug (NEMA 14-50 <-> 6-50 <-> 10-50) - the only difference in these plugs is the NEMA 14-50 contains a 4th blade/connectors for electrical Neutral - EVSE's (including Porsche's) do not use/require an electrical Neutral - so bridging a 14-50 to 6-50 is a non-issue - the fact that you ahve the 6-50 proves this - since there is no Neutral in a 6-50 plug arrangement.

part #7PP.971.678.ED- Porsche Mobile Charge Connect NEMA 14-50 supply cable - un-attached - this is the North American default unless you specify otherwise in your order

I would still just get the adapter pig-tail from Amazon for 1/5th to 1/10th the cost - given low utilization and the easy with which you can use the pig-tail vs. swapping supply cables.

part number for my 14-50 supply cable is 7PP.971.678.ED - see above posts for more details

but I'd get a pig-tail from amazon - cheaper and easier than swapping supply cables IMHO

here is the rosetta stone for the PMC+/PMCC available supply cables from VW/Audi/Porsche

https://www.taycanforum.com/forum/t...rrior-ev-charging-kit.6812/page-2#post-100214

but rather that $200/$150 supply cables - do the following

• one dedicated 50 amp supply cable (doesn't matter which one)
  • $20-$30 50 AMP pig tail adapters from amazon for the "other" plug type(s)
  • example: if you own the 14-50, then pig tails for 6-50, 10-50, Marine shorepower/generator
• one dedicated 30 amp supply cable (doesn't matter which one)
  • pig tail adapters from amazon for the other plug types(s)
  • example: if you own the 14-30, then pig-tails for the 6-30, 10-30, Locking 30-amp generator plug type

when using a 50 amp pig tail use the 50-amp supply cable from VW/Audi/Porsche
when using a 30 amp pig tail use the 30-amp supply cable from VW/Audi/Porsche

DO _NOT_ bridge xx-50 to xx-30 plug types _OR_ xx-30 to xx-50 plug types - the PMC+/PMCC won't know you're using an adapter and may pull too many amps - MIXING amp sizes with pig-tails is unsafe, but bridging NEMA plugs with the same amp rating should be no problem (xx-30 to xx-30 or xx-50 to xx-50)

_OR_ just purchase a 2nd EVSE (like the Tesla Gen2 UMC) and get the adapters for it - at $150/$200 per supply cable - the Porsche stuff is tooooo expensive - you can have a Tesla/Mustart EVSE with all the adapters for less than 2 VW/Audi/Porsche supply cables.

this for example is a great mobile charger (lighter, smaller than the PMC+/PMCC, more rugged) and doesn't overheat like the PMC+/PMCC

NEMA 14-50 40 amp EVSE for $200 that won't overheat…very very reliable

this + TeslaTap is a great mobile EVSE "kit" - you should have a TeslaTap anyways for Hotels/Business's while traveling.

Most of the short extension cord style 14-50 to 6-50 adapters are made in China. I did actually order one that claims to be made in the USA but have not received it yet.

Given that the PMC+ is already a risky product to use, I did not want to give Porsche an opportunity to blame an adapter made in China in case my brother's house burns down while I am charging the car.

BTW, the supplemental instructions I received when the warning sticker was applied to the PMC+ specifically recommends using the industrial grade Hubbell 6-50 or 14-50 outlets and provides the Hubbell part numbers.

nice - the Hubble plugs are great and are what I use in my home setup.

I'm unconcerned about a short pig-tail that is visually and tangebly (weight when holding) beefy - they have better gauge wire than the the Porsche stuff…and the short run of cable (18 inches or less) presents very very little risk.

Personally if you're that concerned the 40 amp Tesla Corded Mobile Connector (NEMA 14-50) is a great product for $200 - the Tesla Universal Mobile Charger Gen2 is also a great product and has a wide range of supply cables - the entire kit is less than $250 for like 6 or 8 adatpers - but it's only 32 amps

Mustart is a good choice - $300 or less - lots of adatpers
Tesla Gen2 UMC is a good choice - $300 or less + optional lots and lots of adatpers
Tesla Corded 14-50 40 amp evse - $200

any of those 3 choices are a better EVSE than the Porsche products.

....any of those 3 choices are a better EVSE than the Porsche products.

Thanks for your suggestions.

I considered the Mustart Gen 2 Travelmaster for $379 and the J+ Booster 2 for $700, but in the end I ordered the Tesla Gen 2 Mobile Charger ($200 from Tesla online store) along with the Lectron Tesla to J1772 adapter ($149 from Lectron website). I had good service from the Tesla Mobile Charger when I owned a Model 3 and I think it is the most compact unit which will facilitate storage in the Taycan as well as my next EV which is likely to have less below cargo storage space.

If the Lectron adapter works well I will probably get a Tesla Gen 3 Wall Charger for $400 and replace the Grizzl-E EVSE that has recently been acting up and not allowing the J1772 plug to release without some drama.

Edit 29-Sep-2022: I changed my mind about using a Tesla-to-J1772 adapter, primarily because I did not like extending the rigid plug from the charging port. I ended up purchasing a Duosida 50 Amp J1772 plug to replace the Tesla plug on the Tesla Gen 2 Mobile Connector. If that conversion turns out well, I will post some details about it.

 

[fgwinn]

Tesla Gen 2 UMC J1772 conversion complete. I ordered the Gen 2 Tesla Mobile Connector with one extra power cord for $245 and then changed the Tesla plug to a J1772 plug following the procedure shown in this YouTube video:



I was not able to use the 50A Duosida J1772 plug I purchased since the wires in the Tesla cable were too small for the 50A pins in the plug. I exchanged the 50A plug for a 32A plug and successfully did the conversion. I don't recommend doing this modificatioin unless you have access to an industrial crimper.

The Tesla Mobile Connector charges at 6.9 kW on a circuit with a 40 Amp breaker and a 6-50 outlet. The Porsche PMC+ charges at 8.6 kW using the same outlet. The PMC+ must assume that the breaker is 50 Amps when the 6-50 power cord is connected.

I am planning to use the Tesla Mobile Connector in my garage until Tesla makes the Gen 3 Wall Connector with J1772 plug available to consumers. If the Porsche dealer does not require the PMC+ EVSE when I trade the Taycan CT, I will sell it on eBay if it is still functioning without overheating.

Can somebody please help a poor confused European?

I have the PMCC wall mounted in the Porsche casing. In my garage in Switzerland it delivers about 10-11 kw (16A on a 400v outlet, I think). No overheating or anything. I use it on the road as well. But it's heavy and impractical (bulky and attracts dust/dirt).

I need a spare charger for destinations with eg. 16A , 220v standard outlets.

I understand the below would do (thanks @daveo4EV): the adapter like in the picture or schuko will take care of de-rating. But I guess the end of the charger going into the car is a Tesla proprietary plug and won't fit the Taycan? Or is it the same type 2 - mennekes?
What do I need for the Taycan? Is that the famous Tesla-tap? thanks!

a European Tesla Mobile Charger comes with a universal plug for Europe - my understanding is no adapter required

please consult with other European Taycan owners, but I'm 90% sure it will "just work".

Correct! If you get the newer versions for the model3, they have the Mennekes type2 connector. And not Tesla proprietary.

I have both a Tesla Wall Connector and the mobile charger. The Wall connector is used all the time for the Taycan. Works great.

I have however had problems with using the mobile unit. For some reason I get some fault message. so try out the unit before purchase. Could very well be my wiring in the house that gives me trouble.
