Despite its schedule at home plugs in then starts charging immediately

[MoonRiver]

I switched back to level 1 charging lately from level 2, hoping the 12v battery gets charged more this way. Then there were a couple of times it started changing once it plugged despite the charging had been scheduled for a later time. I'm talking about charging at home.
Turning off plug and charge didn't help, scheduling to a longer charging hours, set to 11 pm start, end at 10 pm, meaning charge from 11 pm tonight to 10 pm tomorrow night didn't work either. The car accepted the 11 pm to 10 pm scheduling, but still did the plug in and charge.

What have I done wrong?

L1 charging. There’s nothing wrong with L1 charging but the car wont obey the schedule when you’re using it. Why? Because L1 charge time is measured in days not hours.

If the vehicle determines it cannot reach your set SOC in the time frame allotted it with start the charge cycle immediately when plugged in. This is why it is called the preferred charge time not the absolute charge time.

It just needed to add a few percent to reach target 80%, it actually took only a few hours, wouldn't it be able to calculate it doesn't take days, then not to charge until its scheduled time? There was pretty of time to get to 80%.

Your car is charging within the “preferred” charging hours which you have set for 23 hours a day.

You have some misunderstanding going on.

First, "Plug & Charge" is the ability to plug in at an Electrify America or Tesla location and have the vehicle begin charging without having to interact with an app. Charging bill goes to your Ford account. Has NOTHING to do with home charging.

Second, as has been stated, when you do level 1 charging, the car has no idea when it will finish, thinks it cannot, and starts charging. The easiest way to control level 1 charging hours is with a WiFi plug.

If you’re using a smart EVSE (not the Ford mobile, unless you have a 2025) you should be able to back down the charging amperage. I lowered mine from 40 amps to 32 amps. Now the charging sessions take a bit longer so the 12v battery gets more charge (confirmed with CarScanner and Ford PTS). The car still follows the preferred charging schedule.

Finally figured it out. That's because of its being connected to blue oval charging network. The network made it plug and charge no matter what. Charging can be stopped though.
Not until It's cut off from blue oval did it charge as scheduled.

Your experience is similar to what I saw when I first got my Mach-E and I was using the Ford mobile charger on L1.

I never did figure it out like you did, but just switching to L2 even using the exact same charger, made the scheduling work.

At the time it was my belief that basically Ford figures that if you are doing level one charging, you wanna start charging immediately Because you’re not at home.

Because that’s how it always behave for me as soon as I plugged it in, it would start charging.

Also, I see people are still making the same assumption that is it impossible to use L1 because the charging wouldn’t be done overnight. This just isn’t true. Let’s say you have a 20 mile in town commute. That’s 40 miles a day. I can get 4.4 mi./kWh. That means I need less than 9 kWh if I was doing this kind of commute. With L1 you can get about 1.2 kW so it would be less than eight hours.

impact I’m basically retired, and as such, I never had a problem when I was using L1 charging, as far getting it charged overnight.

I will state that you should be sure that the 120 socket that you’re using is on its own circuit. It’s very easy to get full that nothing else is on the circuit in the garage.

This is in fact why I switched to L2, I found out that my garage door was on the same circuit as the outlet I was using And if I was going to put in a new circuit, it might as well be a 240 circuit.

But all this begs one question for me. I don’t use the scanner very much but I have one and from what I could tell the 12 V battery is charged while you’re driving. Just like it would in an ice car. So I really wonder why there’s a concern about how short the charging session is.

Not correct, as was explained prior, see response #6.

Post #6 is the reason.

I had been charging with L2 before I got the idea from here that the longer the HVB charging the more LVB gets charged too. So I plugged it back to 110v, it seems LVB SOC went up since. My wife and I both are retired too. L1 is enough to get around. I have an L2 plug next to the 110 plug, if I need more and quick charges what I have to do is just swap the pigtail of the Ford portable charger and plug in L2.

 

[RickMachE]

L1 is less efficient than L2, i.e. more power is lost during charging, i.e. wasted electricity, about 5% more. So if you charged say 10kWh per day, 365 days a year, you would waste almost 200kW of electricity. For me, that would be $30 a year. Not a lot of money, but wasted money none the less.

Also, as posted often, in the winter level 1 has inadequate power to warm the battery, or even the cabin.

 

[ChrisO]

For what it is worth, when I was using L1, I controlled the schedule with a smart switch, and that worked fine.

And when I checked with a scanner, I saw 90%+ after driving on the SOC for the 12V battery and using L2 charging. I don't really get how the 12V battery can be in a low state of charge unless there are other factors like you don't drive the car very often, or it is really cold, or maybe some added drain from some accessory.
