    model 3 LFP battery charging efficiency

    Not really. I^2*R losses are larger at higher amperages. I noticed my line from the breaker to the 240V outlet actually felt warm when charging at 32A, which got me thinking. If I cut the charging rate to 16A, I reduce the I^2R losses by 75%. I assume there are equivalent losses in the car...

    Supercharger - Woodcliff Lake, NJ

    Stopped here last week just to add 30 pct charge. Nice spot. One minute walk to Panera to grab a cookie and a coffee.

I don't have off-peak rates, but I keep the Off-peak end time set to 6:00 AM, which is before any of my rendom departures. This way I can set departure time...

    scheduled charging on app forgets setting

    I use scheduled departure on the app. I find I have to turn off schedduled departure, set the desired time, and then turn scheduled departure back on. If I skip this regamarole it ignores my time entry and goes back to whatever the previous setting was.

    LFP battery, charge to 100% each night?

    I don't understand the concern about regenerative braking after charging to 100%. Unless you charge up at the top of a high, steep hill, you will discharge the battery accelerating much more than you will recharge it subsequently braking.
