Just a quick update. Porsche dealer said they didn't find anything wrong, and other Taycans at the dealership also don't charge at 11kW either. They also charge ~9.4kW. So I'm at a loss what's going on.

I've also never seen it exceed ~176kW at a DC 350kW charger even when starting from SOC of <20%. They told me it's likely due to the cold temperatures (~33F ambient temp here in Washington).

I'll try calling Porsche USA once I get my vehicle back. It's still at the dealership because they had to replace a control board due to the vehicle lost connectivity completely despite being brand new. I've only had it for a month so far.

taycans can charge at 11kw but only if they are at an 11 kw or bigger EVSE

My EVSE is a Tesla Universal wall connector on a 60A breaker (48A output). It charges my Tesla Model Y at 11.5kW which is 48A@240V. So I know my home equipment can provide 48A charging. The dealership also claims their L2 charger is 48A but I do wonder since they are telling me other Taycans they havec tried only seem to be charging at 40A.

it's pretty well established/documented Taycan is a 48 amp/11 kw EV - my bet is your dealership is "confused" about what EVSE they have, how it's configured, and the rules between breaker size and charge rate…all the Taycan's at the dealership charge at 40 amps, because the only EVSE's at the dealership are all 40 amp EVSE's (is my guess) - so yeah all the Taycan's only charge at 40 amps - duh!!!!

this is what makes this problem so hard to work with Porsche on - they simply don't care to get it right and tease out the limits…

I had an 80amp Grizzl-e charger installed in my garage last week. I am in no way qualified to install a hardwired home charger, so I paid someone to install on the unfinished part of my garage to ensure I did not electrocute myself, or burn down my house in the future..

I am seeing over 10kW speeds when I charge the Taycan now, but the big thing about the upgrade for me is getting 19kW speeds when I charge my Silverado RST. The 40amp charger on the huge truck battery was just not fast enough.

I don't see a Tesla in the drive port, so I was curious on the choice of a Tesla home charger when there are a number of equally as good choices on the market?

^ re Tesla Universal Wall Charger, the integrated adapter is kind of nifty should we ever get a J3400 car. Of course, the same thing can be accomplished just by slapping on (and off) a ~$100 AC adapter. But the cost was almost exactly the same as the $600 EVSE reimbursement from Porsche last year. And I get a kick out of patronizing Magic Docks while not liking Tesla's EVs (or its CEO) so might as well add its EVSE, right? Although even our discontinued 48a JuiceBox works just fine at our primary residence, since we never use any advanced features given the lack of any time-of-day incentives.

I confirmed the dealership's AC charger was only capable of 32A which explains why they never saw any cars pulling higher. There happened to be a Tesla plugged in and Teslas report the max capable by the charger.

I opened a ticket with Porsche NA to see if that goes anywhere but based on my initial convo with them I'm not optimistic.
