Hi,
Was looking at some charging solutions in Baja. Most are claiming 18kw charge. How does one calculate it into miles per hour? Any links to charging calculators or the math on that would be appreciated.

18 kw will deliver around 15Kw to the car that is about 30 miles per hour.
Max charging Kw minus 10% transmission loss multiple by your average mile/Kw consumption is your charging rate miles per hour.
For example
18-1.8=16.2kw
16.2kw x 2miles/kw= 32.4 miles per hour.

Divide kw charge rate by miles per kwh consumption, not multiply

128 kwh battery should gave you 64 miles of driving range. If that's what your truck is doing I am agree with your calculations.

Are these DCFC or just L2/. If L2, the R1T only had an 11.5kW onboard charger, so you’ll be limited to that.

I encourage one and all to discard the idea of trying to think of charging in terms of "miles per hour." It includes guesses at consumption data in the charge calculation, where it has no meaningful place. You will almost never get the number of miles of driving you think you've added via charging, and it will constantly vary so you'll just get frustrated by it.

More importantly, it can make it harder to spot battery issues because changes in driving behavior or seasonal efficiency obfuscate the relationship between energy added and change in state of charge.

This is a common sentiment on the Tesla forums as well. And if possible (I hope it's possible) change any instance of estimated miles to display percentage instead.
