Lots of misinformation in this thread.
When you turn off the car after having set up a charging schedule, there will be two buttons at the bottom of the multimedia screen: Charge Immediately, and Extended Charge. There is not a Charge By Departure Time button. If you want the next charge to be a standard charge from the charge timer, and not immediate, make sure *neither* button is highlighted after you turn off the car.
(Note that the RAV4 EV often still makes charging noises for a minute after you plug in no matter what. Watch the lights above the charge port: if it blinks the left then right lights back and forth, that means that it will wait until the charge timer to charge. It's only charging if it's blinking the left light with no right light, or has a solid left light with a blinking right light.)
If there are not two buttons at the bottom of the multimedia display when you turn off the car, and there is just an Extended Charge button, that means that your charging schedule did not get saved. If so, go back into the EV menu, select Charging & Pre-climate setup, touch the button with the battery, plug and arrow to display the "My Departure Schedule", touch "Schedule Setup", and then set the timers for each day, being sure to press Add for any time you set on any day. Once you're done, press the back arrow until you're back to the My Departure Schedule screen, and be sure to click on Save there. If you're still having trouble with it after that, you may want to go to the dealer.
On Schedule EV (both EV-A and EV-B), the lowest rates are between 11pm - 7am Monday through Friday and any time on Saturday and Sunday except 3pm - 7pm. However, for the period between the second Sunday in March and the first Sunday in April as well as the last Sunday in October to the first Sunday in November, those times will all be one hour later as PG&E adjusts for daylight savings time.
With a 40A Leviton EVSE, if you set the charge schedule for a departure time of 6:45AM every day, you will always get a full charge during the periods with the lowest rates.
