If you want SIMPLE, I think there are 10 segments to the battery charge indication on the dash.... Divide the time it takes to actually charge the car. I think the 120 at 8 am is 13 hours??? so 1.3 hours per segment. Just figure for all three settings of charging. 120 8 amp 120 at 12 amp and 220v ac. multiply the number (1.3 for example) by the number of segments out and you will have a reasonable guess to charge time.
works for me.
