EV-TOU-5 gives you more than one cheap weekday window
If a vehicle is available overnight, midnight–6 a.m. is the obvious super-off-peak opportunity. A vehicle parked at home or work during the day may also be able to use the 10 a.m.–2 p.m. super-off-peak period. The best choice depends on when the car is plugged in and how much energy it needs.
Weekend behavior is different
On weekends and listed holidays, SDG&E shows super-off-peak from midnight to 2 p.m. This is why a charging planner needs the day type instead of applying a weekday schedule to every day.
