Have you tried charging at a friend's home who lives in another neighbourhood? Your next door neighbour is probably on the same electrical distribution system, so your voltages going into the house might be very similar. I'm not entirely sure if this is the real culprit, but just trying to eliminate as many culprits as possible. Does your neighbour's Kia charge at your house? That's also something to test. If his car charges at your house, but not yours, then we know your infrastructure is fine. Something with the update changed the sensitivity to voltage and flags it as a safety concern and doesn't start charging.

Charging speed varies due to battery temperature. So if your battery was cold when you first plugged it in, then maybe it was slow because of it. As the vehicle charges, it also heats up the battery, so the speed would go up eventually. I have noticed when I DC charge my car on a cold battery (around 8C), the speed I get is closer to 50kw/h. But if I preconditioned it, and battery temp is at 32C, then I can get 250kw/h if battery's SoC is low enough for it to reach that speed. The higher the SoC, the slower the charging speed will be.

No, we are talking AC here. There’s no scenario where the battery can’t handle a full AC charge. And 5 minutes on AC I doesn’t change battery temperature much.

You might be limited from a full DC speed if you plug in with a frozen battery but a car that has been driven even In winter is going to have a 60°F battery.

I did a post in another thread about preconditioning and how it’s not always necessary, where I drove down to single digits in freezing temps and then still got ~200kw straightaway. Battery warmed up very quickly too. I might have gotten all the way to 270kw with precondition but still got to 80% in a little less than 23 minutes with no precondition.

Ah you're right, I forgot for AC, there is no preconditioning. However, for my car in particular, I have never gotten 200kw right away without preconditioning. If I don't precondition, speed is always slow. I wonder why that is. It's the same car, but different speeds. Maybe my high voltage charging system is defective and responsible for all my charging issues.

No I haven't but that's a really good call out. It's tough to find folks in a different neighbourhood though so that will take some time.

Yep, we did and it worked.

Hi,
I recently had the update but my issues with charging at home may be related.

• Year and Model: Macan
• Your Location: UK
• Charger at Home: Ohme Charger
• Charging Port: Only tried one side (driver)
• Timeline: Observed on first charge following upgrade
• Troubleshooting Steps Taken: New feature in app allows to toggle for direct charge, appears to allow charging to take place. Also constantly needing to delete planned departure. Utility company also appears to have option to now turn off economic charging. Option was previously switched off.
• Current Status: The car keeps attempting to default to economic charging and recreating planned departures so deferring the charging. Have managed to charge via the home charger keeping an eye and toggling direct charge on several occasions.

I hope that helps. Otherwise no other issues with update and my SoC % is updating unlike prior to update.

I am having the same issue with same charger post update. Scheduled departures keep appearing in the vehicle.

Year and Model: 2024 Macan 4S
Your Location: UK
Charger at Home: Ohme Charger (OVO Charge App)
Charging Port: Only tried one side (Passenger LH)
Timeline: Observed on first charge following upgrade
Troubleshooting Steps Taken: Deleted departures but they keep reappearing
Current Status: The car keeps attempting to default to economic charging and recreating planned departures so deferring the charging.

Can’t see direct charging option on my app whilst charging it seems

Pickup my car this morning after getting the update and open campaigns done.

Charging Port: Driver side AC
Timeline: Tested after update given this thread - normal charging behavior was experienced.

So if your neighbour can charge at your house, but you can't charge at his, then to me it indicates something about the neighbourhood's electricity is flagging a safety concern in your car in particular. Like the update made it extra sensitive and red flags it during the initial handshake, so it stops the charging process. I would try charging your car at an AC charging station away from your house if you can't find a friend that has an EV charger at home. This at least will tell you, that your car can still charge elsewhere, it's just your neighbourhood. When you go to charging stations, it's all hardwired, so it should be better with lower THD (Total Harmonic Distortions, aka "electrical noise"). What is your dealer doing about all of this?

So in your case, it's not that you can't charge at all at home, it's just that it changes the speed of your charging? I'm not sure what economic charging is. Maybe that's something to do with your charger. I'm guessing Ohme is hardwired into your home. Maybe that's why you can still charge at home, but only in economic charging. Maybe it's worth talking to Ohme about your situation.

It seems like those who can't charge don't have a hardwired EVSE. I'm starting to wonder what parameters they changed in the update to "optimize charging". Because charging was changed during this last update.

Taking my car to the dealership tomorrow. Let's see what they say.

Did you delete the departures via the app or in the car.

From Porsche tech support last year:

“Our technical team has identified the cause of the issue: if five departures are stored in the list and the preferred charging times option is activated for the last departure, the departure list can become corrupted. When this happens, scheduled functions are no longer adjustable in the app, even though immediate remote functions such as climate control and charging adjustments continue to work.

To restore full functionality, please delete the stored departures directly in your vehicle. Once the list has been cleared, the departure timers will be visible again in the app and scheduling can be adjusted as usual.”

I took my car to my neighbour’s house who is like a a few houses away on the same street, and my car doesn’t charge at her house. But her cars charges at mine. I think this is the same situation you’re encountering. Let Porsche know this when you bring in your car.

I’ve deleted from both car and app. I think it’s the Energy provider (OVO) charging app that is creating the spurious departure times as a means of controlling charging at set times as it seems to start off a week in advance and then adjusts
