Level 2 charging rate with a 50 amp capacity

Fremont Porsche, but be aware, after plug and charge was back, my charging went from 11kw to 8.9kw after the optional software updates.

Did they flag it as a failure, needing repair back up to spec? Or did you sign some fine print you didn't realize said that you agreed to this?

No, i just told my advisor, that after my OBC replacement, my plug and charged was no longer working, and it has disappeared in my PCM. when i picked it up, they told me that there were some optional updates to the obc and high voltage battery, and my plug and charge is back working. Says the same thing on my service record. When i got home to charge, is when i noticed im now charging at 8.9 in the pcm while it was charging at 11kw before the plug and charge wasnt working.

Which model year Taycan? Did you report that their update broke your charging speed at home?

i have a 2021 turbo S. No, i haven't reported the neutering of the charging speed with a hardwired set up. I was lurking on the forum to see if anyone else had a remedy or better luck... but it looks like this is what we all have to live with and is now known as normal.

Isn't it funny how we normalize neutering the products by manufacturers, taking away capabilities that were sold to us?

I agree with this is "spirit" and I've been one of the biggest voices about this issue…

but I think we've just lost this one - Porsche has always had a wonky relationship with OBC max charge rate in North America and their lack of engagement and certainty on this issue I've always considered a bit of an indication they are not quite all in on EV's for a company known for sweating the details…

they have NEVER had a straight answer for the max charge rate in North American of the Taycan and can't even seem to reconcile the fact that a mobile EVSE can't be more than 9.6 KW because there not a NEMA plug outlet with large enough capacity to offer more than 9.6 kW…yet their website still list various max charging capacities across their EV/PHEV products in standard equipment…

it frankly shameful and just sloppy across the board…

we lose this one to sloppiness not to malice and it's a tacit admission that their OBC's are utter crap

someone knows why they are doing this - but they aren't communicating very effectively about the core reasons…

My build sheet clearly states 19.2kW, no ambiguities.

too bad Prosche can't engineer an OBC that actually works at that capacity …

I have 19.2KW charger, so not worry about that. I only charge at 40A at home, as my breakers are 50A for my chargers. I should tell Steven’s creek to call them and figure it out haha. I will ping my adviser and see what is going on.

FWIW: I’m charging to 100% for my first cold weather, snowy road trip to our country house direct in my (new to me) ‘24 ST GTS with standard OBC. I have a 48V Grizzly (made in Canada) charger on a 60 Amp circuit with tons of headroom (my house has 600 Amp, not a typo, service and this is on a small sub panel with no other significant draws right now)

Here’s what I’m seeing at the top of the battery (lower I see 11 in the car)

Note the difference between what the charger is putting out and the car is taking in!
Also, if you look at the pictures you’ll see the time of each shot. As time goes on the charge number for the car is growing, I’m assuming the missing power is heating the battery pack. The car is sitting in my relatively cold garage and hasn’t been driven since this morning so she’s pretty cold.

On a side note: I wish I could charge to mileage vs percent. I only need 300kms since I’m driving 240kms and I want a nice safety margin but i would need to babysit the car and shut it off to get the distance right.

Distance is an estimate based on recent driving, traffic, weather, etc. It's not a guarantee you can drive that far. This means 300km of range will be a different percentage depending on your recent drives. Should you encounter colder temperatures, rain/snow, drive faster, or drive a different path with more hills, your range will change.

Perhaps too bad for them, as they sold a car with warranty, they have to repair it to original specifications, or negotiate satisfactory compensation. Repairing the car with parts with half the performance specification is failing to deliver on warranty. It would be like welding the passenger door shut to fix a leak and claiming problem is repaired.

Out of curiosity, in your educated opinion, what capacity OBC did they engineer correctly? Do you really think the 11kW OBCs are not failing?

Good point. I guess I’m looking for certainty which I never got from my 5.5L twin turbo either, just a rough area that the needle for the gas gauge would sit in. Funny I’m more demanding of the electric car! In retrospect, I may have had less range anxiety with a J1.2. I’ll tell you tomorrow night!
