This is likely a specific Ford Charge Station Pro issue you're encoutering - not a Preferred Charge Times specific issue. To prevent this issue in the short term, you can either plug the vehicle in and then click the release button a few times (without unplugging), or plug the vehicle in and wait a few moments before leaving - the red flashing light on the vehicle will appear quickly so waiting a few seconds to make sure the lights don't turn red (and if they do, unplugging and replugging) will avoid this issue.Thank you--this is very helpful.
It explains that the charging window is overridden by the software if it calculates that it needs more time to reach the slider set requested charge than the window provides. It says that in that case, the charger will start charging earlier than the set window in order to get the car to the set SOC by the end of the window. It further states that if you want it to stop at the end of the charging window, you must check to make sure it can do so and reach your set SOC. If it won't, it will charge longer, so if you want it to stop, you must readjust your SOC. (Personally, I would like it to just stop and then resume when the next window opens. Otherwise, I would use the Departure option if I wanted full SOC regardless of when it charged.)
But this is not what actually happens to those of us reporting the problem. Instead, when plugging in before the start of the window, the charge never even begins. Only when we plug in at or after the start of the window do we get any charge. If we plug in earlier--say an hour after the window closes the day before--it does not start charging the next time the window is open.
Rather, it doesn't charge at all. And you only find this out when you go to the car and physically unplug it. Then you get a flashing red on the charging port LED and the app tells you there was a charging error.
So the programmers have not succeeded in programming even to their stated goal. I believe that's why they have apparently agreed to fix the start of the charging process at the beginning of the charging window.
To respond to your suggestion, I for one have verified SOC (80% for us), we have only one charging window (10am-5pm to charge primarily on solar,) we have only one charger in the app (Ford Pro), we have no departure time charging set, and we rarely use the Start Charging or Stop Charging command in the app (but these seem to work when we manually use them.) If we plug in after the start of the window, all works. If we plug in before the start of the window, we get a charging error but only when we physically go down to check and unplug and replug.
Please also ensure your Ford Charge Station Pro is on WiFi so it can receive bug fix software updates.
