My car is currently being build and I opted for the dual charger and high power wall connector. I am running a 100 amp circuit so I will be able to charge at 80amps, I know I can set the charge rate on the screen in the car from as low as 5 amps to as high as 80 amps and anywhere in between. Does anyone know at which amp rate the charger is at its highest efficiency , and does anyone know what amp rate is optimal for the batteries longevity ? As an example if I have 24 hours before I need to drive the car again and I only need to charge 40 miles to full, so speed of charge not being an issue. Would I want to set the amps to 5, 10, 20 .......80 or does it simply not matter?
