Level 2 charging rate with a 50 amp capacity

[SoccerMan94043]

Wow, my 2001 GT2 with real mileage on it is tight as a new car… I assumed my Taycan would be as well built. I guess there’s two possibilities, 1) you’ve had a bad build, 2) Porsche isn’t making the same effort that they used to.

Door card rattles are common on Taycans. I have two on my 2025: driver's door and passenger back (I think)

Also, my build sheet is specifically listing an 11 Kw charger on it. So no ambiguity IMO.

You are in a somewhat unique position where your build sheet has 11kW showing. Have you tried booking an appointment with service telling them the charger has degraded performance, therefore requires a warranty fix? I'd be curious what their answer would be (maybe something canned from Porsche, but it would still be better than radio silence Porsche has been utilizing so far).

Or maybe option 3) Porsche used to have loud engines to mask the rattles.

I installed the latest software update yesterday. Here is what I got just afterwards:

Update: I have been monitoring my charging rate since I joined this conversation. I noticed last night that my rate was a little lower this time.

Well, I think this OBC "update" is the end for me. Between the endless string of recalls, week at a time repairs at the dealer, door rattles that are taking months to resolve and a downgrade to the charger that limits my home charging to about 1/2 of what it was previously, I've had enough. I really like how the Taycan looks and drives, but the ownership experience with the J1.1 has been a lot less than what a $190k USD car should be.
Maybe I'll find a J1.2 that fits my needs, but until then I will watch to see how things go in the ownership circle online. Best of luck to everyone, I hope Porsche gets their act together on the performance EV front because there is so much potential!

Oops that is...the neuter in action, as it appears, getting you down slowly, next charge expected to hit below 9kW.

As an owner of both a ‘20 and a ‘25, i would say that there are performance improvements in the second generation but the ownership experience has been at least as disappointing. in some respects more so.

My J1.1 at least for now still charges at the higher 11 kW draw rate and aside from a complete battery replacement has been pretty much bulletproof. the J1.2 has had numerous mechanical failures requiring many new parts and extensive delays in getting repairs done (measured in months, not weeks). Porsche’s ability to provide product support and service (not a slag on the dealer but rather the manufacturer) is abysmal.

I will be installing the update today, so going under the knife of AC charging nip and reporting the results soon enough. I cannot let you suffer alone. 9.9 is not bad if it does not go any lower, but usually I get same strong 10.4+ before the install.

9.9 is BEST case, you're looking at 8.5!!!
20% drop in charging speed.

9.9kw in the car is likely not a nerfed OBC, as it translates to ~11.0kW at the EVSE, so still an 11kW EVSE. Slightly lower than usual reading is probably due to lower voltage, which can very.

I am not sure what to think. I was going to install the update this evening, but as I got back in the car after work, the update disappeared from the Notifications. No way to tell if it was installed, as I simply clicked on it to take the picture. I am now charging at home at my normal 10.4kW speed at the car with my EVSE reporting 11.43kW output.

Anyone else who is waiting to install it, saw it just disappear completely?

Is it possible to lose 1.1 kW between the EVSE and the car? That would be a lot of heat to dissipate -- 1100W is a hair dryer on full blast.

BEFORE the update, my 48A EVSE was putting out 11 point something and my car reported it was "receiving" 10.3-5 (you can see I posted a photo of both my charger and my car somewhere in this thread)
I believe that losses include running the fans while the car is charging, heating/cooling the cabin, and feeding the magic gremlins that make sure that the Taycan has mystical problems nobody can explain.

AC/DC losses are commonly 10% loss - 11,000 watts (11kw) is an 1,100 watt loss just for the AC/DC conversion overhead

the OBC is the ac/dc converter that changes ac power to the dc power required by the battery - the overhead in this conversion is inline with nominal industry expectations - 7% loss is best case under ideal conditions and narrow use cases…10% is about the best everyone can do in terms of loss for this type of battery charging
