As stated many times, this is perfectly within the expected charging performance in those conditions. But the gap is more than just whether you spent 20 minutes preconditioning the battery. There are many more variables involved. Preconditioning is 3kW of heating power. It cannot change your...

Why? What are you trying to heat the battery for? If you're in Barcelona, it's well above freezing. There's no way the battery is cold enough to need any heat. If you're charging at home every night, then you don't have to worry about fast charge conditioning, so the battery still does not need...

You have the answer in this thread. Charging speed is 36% less efficient at 0C than 25C. It is 12-15% less efficient at 15C than 25C. Not half. To be 50% less efficient, the battery would need to be over 35C colder, a difference far, far beyond what preconditioning can achieve. Those are the...

I don't follow. The curve shows that between 49 and 51 percent, the maximum charging of the car is 205 to 199kW. Nothing about that says it "should do over 200kW". I regularly get 190-195kW at 50% on a 350kW charger. What's the issue?

It's a good question, and the answer is a combination of factors: Automatic conditioning of the battery in cold temperatures (below freezing, the car doesn't care where it's going and will warm itself) Normal heat accumulation of driving, particularly with a lot of switching back and forth with...

I can't change the weather. The data is all right there. I don't know what exactly you think would change if the battery started 10 degrees colder. You keep ignoring the fundamental flaw in your claim: 8-10 degrees can't halve your charging speed. What you can see is that driving does maintain...

It's labeled in the manual. I think it's near the VIN plate? Or the B pillar? Can't remember off the top of my head.

If you have fully charged the battery when you leave home, the temperature doesn't matter until you're nearing your charging stop. Just use the planner and drive. Let the car condition itself. Don't overthink it and don't try to outsmart it.

An 8 degree temperature difference cannot cause a 140kW change in charging speed. I don't know what's stopping you from understanding this. It's not physically possible. The fact that the entire post went that far over your head is your own problem. Nothing changes if you start at 5C instead...

Correct. Supported by Porsche, not by the technology. Sure there are. But even if there weren't, the 2024-2025 Macan does have both an external and internal NFC reader. The NFC door handles are not required except by Porsche design. That went largely out the window when Porsche decided to make...

It is true for everyone, my guy. Again, you misunderstand. You can change the starting and ending temperatures to anything you like. The math will still be the same. You can't add more than 10C by preheating, and 10C can't slow charging by more than 15%. The "perfect temperature" you're...

Neither your experience nor anyone else's halves the charging time. This is at least the 20th time you have made this claim with zero evidence and completely irrelevant references to state of charge and voltage, instead of the only thing that preconditioning changes: temperature. It would take...

So just for the sake of moving some of the actual science of EV charging into this thread, I'm starting from the beginning. This will hopefully help explain when the car is or isn't conditioning the battery and why. For lithium batteries in current EVs, the temperature/behavior looks...

That's not relevant to anything. Jesus. No, you haven't. You have proven that charging at twice the speed takes half the time. No one is arguing otherwise. The issue is that preconditioning cannot double your charging speed at any temperature. I don't know how many times you need to hear it to...

The times are not invented, but for the millionth time, they're not testing preconditioning vs. not. A screenshot of two different sessions with no temperature data is not showing anything useful. Especially one claiming to "precondition" on an August day where the ambient temperature was 18C...
