I finally got my car and garage set up so that I can use a Tesla wall charger to charge the car at up to 80 amps. I did this to have the flexibility to charge the car quickly if needed but the reality is, more often than not, I have overnight to charge the car and so can do so at a much lower amperage if there is some advantage to doing so. The question is, is it more efficient to charge at a lower rate? I notice the wires and breaker get noticably warmer at 80A than at 40A or 50A. Is it easier on "the system" (battery, charger, breaker, etc) to use a lower amperage? Thanks for your thoughts.
