timed charging

Was it not charged at all or charged but not completed? The charging schedule can be interrupted by overriding it with the Charge Now session. I think if you do this before the scheduled time of charge, the next session will not start. There may be other reasons that the scheduled charge does not start such as power outage or unintended/intended power interruption by unplugging from the wall. Not exactly sure how the EVSE react in each case, but I have seen the warning on the dash with something like "Power was interrupted during charge"

 

Is the Prime’s clock set correctly?

Did you remember to press the lock button at the charging port? The first time I tried to charge my Prime based on the schedule, I’m pretty sure I forgot to press the lock button so it didn’t charge.

 

The lock button makes no difference. I charged twice per day for 3 years using the schedule and never pressed it. Worked fine everytime.

 

Good to know. I must have done something else wrong then.

 

It may sound dumb, but did you confirm the AM/PM for both the clock and timer are right? If one of them is set incorrectly, that would result in no charge in your scenario (assuming it was plugged in <12 hours before).

Kinda like the first step in troubleshooting is to make sure your thing is plugged in...

Just a thought...

 

Another thing to watch out for is what days of the week the charge schedule is set to repeat. On my 2021, if I don't specifically specify which days of the week the schedule runs it won't run at all. Also, make sure the date and year is set correctly (so the car knows which day of the week today is).
