I'm trying to plan out my Model 3 charging strategy given that my garage isn't wired with 240V. My commute is only about 20 miles total per day so 120V should work 99% of the time. Weekend trips might take my battery down to 10% upon reaching home, but I can just charge at 120V every night during the week to gradually reach a higher SOC every morning.
My electric dryer plug is inside the house right inside the garage door so the UMC should be able to reach. My thoughts are that I can unplug the dryer on the rare occasion where I need to top off quickly at home (coming home from work and heading out soon on a road trip). This should only be a couple of times per year.
Is there anything wrong with planning on trickle charging at 120V 99% of the time as long as I have the option of unplugging my dryer for quick charging? Is 120V less efficient wall-to-wheel?
