Max available charging rate calculation display and tips to improve it in real time.

Porsche just came out with a max charging rate available metric for it's new Taycan. This would be an awesome metric to know when traveling and should have hints to maximum charging speed.

Can you clarify it a little more?

How is it different from Tesla showing the capabilities of the Superchargers?

If you go to a 250 supercharger it will almost never charge at that. It would be nice to know for example that your battery is too cold and limited to 60kw. As the battery is preconditioned you can see the max charge rate increase. Also state of charge limits max charging. It would also be nice to see a time to 80% charge at battery limit.

Okay, I get it. But it is actually pretty easy.

Below 10-15% at V3 gets you full speed.
At 50% you are down to 150 kW

Once you are at the Supercharger, all the info is essentially there.

Tesla tries to simplify things and making people think that the information is important, gets people confused.

While on the road, the navigation does the calculations for you, it tells you how long you will need to stop.

And hence my recommendation of when road tripping, run from 5% to 50% charge. The time you spend charging will be significantly less than if you go 20-80%. That's because 250kW never can kick in at 20-80%.

Right, but that's an estimate and not a real value. If you are going to a supercharger you don't really know until you plug in. The actual charging curve varies a lot. The car knows and should tell you.

But what is it going to mean to you? What would you do different?

As long as the pedestal is working correctly, and the battery is pre-conditioned, it is nothing more than a chart. It really doesn't vary much.

And honestly, with batteries, EVERYTHING is an estimate.
