Do you guys think it may have to do with this?

Not at all. What you linked is a FUD story most likely spun from the European onboard charger issue (which was an actual problem, but nowhere near a “scandal” some people have overblown it into). This is about North American PMCC (EVSE).Do you guys think it may have to do with this?
no - I may be tiresome but at least I try and stick to the facts that everyone can verify for themselves and then agree or disagree with meDo you guys think it may have to do with this?
I just bought another Wallbox Pulsar Plus 40a to replace my PMCC at our main house. I’ve had one at our lakehouse for a year and a half and it has been great. Reliable and fast with lots of features.so team - your $1120 North American 40 amp PMCC/Outdoor-grill/Toaster is now being updated via OTA update to a restricted 20 ampswith _NO_ override possible to restore full 40 amp capacitythat has to be reset after each power cycle on/off before you charge your vehicle.
Cayenne forum owners are claiming OTA update for PMCC now forces their max charge rate to 20 amps - with no settings override possible…[UPDATE - they are wrong - it now defaults to 20 amps and can be overridden, but the override has be performed after each power cycle of the PMCC]

can anyone confirm/deny their PMCC is now restricted to 20 amps maximum charge rate?
now confirmed - see post #26
OMG -ifthey are in fact doing this - wow - simply wow - how disappointing - time to break out the affordable higher quality alternatives - also I'd request your money back if you paid $1120 as any option for your PMCC.
_IF_ true - I have not verified this with my personal PMCC's…
wow simply wow - and disappointing is an understatement.
thank you @AndiLIf your PMCC is not updated, you can check the release notes at https://contact.porsche.com/usa/accessoriesandservices/porscheservice/software-update/ by entering your serial number.

- Optimization of PLC communication between Porsche Mobile Charger Connect and Porsche Home Energy Manager
- Optimization and robustness measures to the installed software
- Optimization of the 2.4 GHz WiFi frequency
The change in default to 20 amp charging rate is likely included without mention in thethey seem to be missing the following bullet point
- North American PMCC units will now default to 20 amp charging rate (4.8 kW) for improved safety and thermal behavior - this default value can be temporarily overridding using the PMCC's charging current settings via the "gear" menu
I was thinking the same thingThe change in default to 20 amp charging rate is likely included without mention in the
bullet point. It Improves "robustness".

When I took my vehicle in for the ANA6 update they asked me to bring my charger, PMC+, in for an update. Now I haven't ever even plugged in the PMC+ since I have a PWCC installed in my garage (Zero issues with the PWCC btw). My service rep did say that I will get new manuals for the PMC+ once they are in stock.the PMC+ is not updated at this time - this discussion only related to the PMCC unit to my knowledge - I welcome any corrections.
My SA said the same thing to me when I got the ANA6 update. So why are some saying it was an OTA and we have to bring ours in?When I took my vehicle in for the ANA6 update they asked me to bring my charger, PMC+, in for an update.

The mobile chargers do seem a bit pricey. My PMC+ lives in one of the cabinets in my garage and only gets put into the car for longer trips. I suppose I should actually plug it in at some point and test it
bringing it in is to inspect the unit's looking for signs of electrical/thremal stress - there are known issues with cables melting and signs of stress in the J-1772 cable vehicle charging plug - and written instructions from porsche for what to look for to see if the PMCC unit has been having stress while chargingMy SA said the same thing to me when I got the ANA6 update.

Still not as bad as Tesla which advertised 691hp for P85D's, only to later admit that it was battery limited to 463hp from the factory. In other words, in order to achieve the advertised spec you would have had to replace the $40K battery in the car with one you'd have to design yourself because Tesla did not at that time sell a powerful enough battery.to achieve Porsche specified charge duration of 9.5 hour (see below) - you will need to temporarily adjust your PMCC each time you use it - or purchase an alternate 9.6 kW EVSE from a vendor other than Porsche.
That argument would last about 1 minute in court, if it isn't thrown out of court before then.a 40 amp settign is if the customer manually overrode our default safety recommendations...
Well, they could make an argument that changing the setting outside of default, the customer acknowledges they know what they are doing, especially if they hide it under customer_service. For example, if you change the charger to 40A and you are plugged into a Canadian legal NEMA 14-50 with only a 40A cabling+breaker, if a fire results, they could claim you are responsible. This actually happened with Tesla mobile chargers, there was a fire, hence today's version is only 32A (which also allowed them to cost optimize, but at first they just sold 40A chargers limited to 32A, and unlimited 40A as "hardwired"). 32A will trip a 30A breaker, and is safe to use on 40A and 50A breakers (all legal to be behind a NEMA-14-50), so potential safety issues mitigated.That argument would last about 1 minute in court, if it isn't thrown out of court before then.
if a product is operating within defined spec (as in this case, charging at 40a) you can't escape liability by saying you recommended something else.
As far as "manually overriding" the recommendation, they describe that (a) you can do that and (b) here is how, and the change that they allow to that setting is within their specs. This is not some secret back door hack that enables the charger to operate at 60a or something else out of spec.
