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...

What you observed was not due to preconditioning alone. It is not possible within the laws of physics. It truly is that simple. 270 vs. 130 is absolutely, positively, under no questions, impossible for preconditioning. You are losing 1-5 minutes per charging stop, whether that stop is 5...

It was. The Macan has everything required. Porsche chose to modify the location of exterior NFC readers. Neither NFC nor a door handle reader location is required hardware for Digital Key. Either Porsche doesn't trust UWB on its own for phone applications or they think drivers are too stupid to...

Your post is entirely accurate except for the use of the word "ensure" in the sentence above. Pre-conditioning only helps get the battery to temperature, and will only trigger if the battery temperature is under 20C, which is in ambient temperatures under 5C. It cannot close a gap greater than 10C.

That's just not how it works. The difference between 25C and 15C is not double. No, it's not a trick. It's to prevent wild-ass claims conflating multiple factors in charging speed and time. The math is very clear. Preconditioning can add 10C to the starting battery temperature at a cost of...

5C and 5 miles of driving is too warm and too short a drive to see anything from preconditioning. There is no target temperature per se. The cycle will, after 30 minutes or so, raise the battery by up to ~10C from wherever it started. It will not raise the battery temperature above about 25C...

It simply is not true. You can look at the Porsche Taycan graph posted by degenatron. The difference between preconditiong and not is ~10C. There is no point on the curve where a 10C difference in battery temperature doubles charging performance. It shows a 3.5 minute loss from 20C to 10C...

You're just wasting power, my guy. Burning almost 15% of the power you put in at the charging stop isn't saving you time or money just because the first number you see is higher. You only added net 19kWh on the charging stop, and even at 16C and a 120kW starting charge speed, the initial...
