Would there be any benefits to charging slow (lowering the Amps in the car) on a NEMA 14-50 capable of drawing 32 Amps? My commute is very predictable every day and charging my M3 LR AWD takes about 2-3 hours to reach 80% SOC.
I tried 2 other approaches while charging with NEMA 14-50 at 32 Amps:
(a) start charging as soon as I get home and leave it plugged in till next day morning and
(b) schedule the start time 3 hours before I leave next day morning.
Approach (b) has the advantage of leaving the car at 80% SOC for a short period of time daily. I do not have an EVSE so I am not sure what the most efficient way of charging is. Since I will be repeating this every day for at least next 5-8 years, I am wondering if there is a better charging habit I should follow.
