If you know the time you are leaving in the morning it is easy enough to set a delayed start time that matches the charge you want when you leave.
My battery holds 20 kWh when full, so each 10% SoC is 2 kWh
My EVSE sends 6 kWh an hour to the battery
-- so 10% charge every 20 minutes
Say I arrive with 30% SoC and want to leave at 7:30 am with 80%
100 minutes charge time needed ( 50% * 20 minutes/10%)
I set the delayed start timer to 5:50 am
If people would like to print out a nomogram to keep in the car for easy reference, let me know.
