I'm creating a Google spread sheet to calculate trips between many Superchargers. I have a lot of data I can automatically calculate, it works well, but I want to auto calculate the time I need to charge at a Supercharger. I have the battery percentage when I arrive and to how much I have to charge. I also have the Supercharger charge curve. What I can't figure out is a way to calculate the charge-time going say from 10% to 60% based on the SuC charge curve. Anyone can help me with that?
