Let me give you a real example:

1. You receive a discount in TOD metering schemes, but outside of those hours, the rate is very expensive. My weekday hours are 11 PM to 9 AM.
2. I arrived home from a trip a couple of days ago with 10% charge. My normal charge maximum is 90% (AWD ER).
3. When I plugged in for my overnight charge, the car started charging immediately (at the expensive rates). I was confused as the car is only supposed to charge at home during preferred rates.
4. It turns out that the car would have been unable to charge to 90% during the allotted off-peak hours, so it was gobbling expensive energy to try to get to 90% by 9 AM.
5. I had to manually adjust the max charge to 75%; then the next night went back to 90%.

So this feature would have enabled all of this automatically and prevented any charging at the higher rates.
That’s just a bug with your car ignoring your set charging window, which is known to happen.

No, the car prioritized meeting desired charge by departure over charge in window.

I can see how this would be an issue with using the provided mobile EVSE or a 'dumb' EVSE. I have my TOU charging schedule set in the car and also on my ChargePoint Home Flex wall unit too. So even if the car is asking to charge outside of the TOU window the ChargePoint won't allow it.

So one thing I have noticed, if you use this new feature, there is no option to set a Max charge. So it charges to 100% no matter what. Not a fan of that at all.

Yes, you are correct that it's a dumb EVSE. It's not programmable nor is it connected. It's a 10-year old Bosch that my power company gave me as an incentive along with separate meter and wiring to my garage when I leased a Gen 1 Volt. All it wants to do is supply power, and it's up to the car to tell it "no" or "yes."

So you can't set the max and it charged to 100% but just realized it sent this when it got to 100%.

Turns out I can't use this feature. I set the minimum to 80%, but it kept charging to 100%. I live at the top of a 800' hill (5-8% grade) and use regen all the way down. When the battery is at 100%, it can't regen smoothly and the car vibrates all the way down the hill. Since it doesn't support a max charge, I turned it off.

Yep. I'm gonna turn it off on mine too. I just don't like charging to 100% unless I'll be taking off pretty quick after it hits 100.

Doesn't that prevent maintenance cooling of the battery outside the charge window?

Yes, but it doesn't get hot enough in my attached garage to need cooling. We don't get many 100+ degree days here in SE Michigan. Even if it did get that hot in the garage it's easy to override my home charger schedule from the ChargePoint app.

Interestingly, Ford's Connected Charge Station doesn't have charge scheduling options yet.

well, now you know why it's "early access" ?
So, I’m NOT in this particular Early Access Campaign (at least according to the Early Access website), yet I’ve noticed this EXACT behavior recently and was puzzled by it. I have the charging level set to 90% in the app, and get the message that charging to 90% was completed, but on the app home screen, charging was reported as being completed to 100%, and in the car, it was reported to be completed to 100% on the instrument cluster. I’ve been puzzled by this.

My Early Access page still shows i'm not active in any campaigns as well.
