jsamp Posted March 30, 2019 at 04:32 AM Report Share Posted March 30, 2019 at 04:32 AM So muzicman61 and I have been having an offline conversation about something that has us stumped, so I thought we'd take it to the forums to see if anyone has a better understanding of this charging behavior. There have been claims that when you plug in on a value charge, that it will immediately charge to ~10% (if it is below that) then stop charging until your prescribed value charge time. muzicman61 sees this behavior when he charges at home. I do not. The only two differences we can find are 1) the years of the car (my 2015 vs his 2017) and 2) I only use the default profile on MFT (center screen) where he uses the web site to program his custom profiles. When I plug in it does nothing until my 3am charging time then it starts charging. So the questions are: Do any of you know why he sees charging to 10% then a pause until his value charge profile, but I don't?Who of you see this behavior and what year is your car and how do you set your charging profiles? default? MFT, MFM? Does this only happen when the car is plugged in and depleted to hybrid mode? I typically plug in with a small % still on the battery, though not always. Trying to get to the bottom of this... Quote Link to comment Share on other sites More sharing options...
murphy Posted March 30, 2019 at 10:47 AM Report Share Posted March 30, 2019 at 10:47 AM I can't help with this one. I've never used value charging. My electricity costs the same all day, every day. Value charging is of no value to me. Quote Link to comment Share on other sites More sharing options...
Timewellspent Posted March 31, 2019 at 03:57 PM Report Share Posted March 31, 2019 at 03:57 PM I have a 2015 and once in awhile it will charge for a bit when I first plug in and then shut off until my value charge time. Sometimes it will charge fully too without waiting for my value time. Not sure why either of those happen. I have value charge set for at home from 1am to 6am, but at work I use default and have it charge when plugged in. Even though my electric costs the same all day, I do the value charge at night so I'm not charging a hot battery all the time and also have it run the fans to help cool the battery before it starts to charge.

jsamp Posted March 31, 2019 at 09:22 PM Author Report Share Posted March 31, 2019 at 09:22 PM I, too have constant electricity costs, but use value charging to A) charge when the battery is cooler early in the morning and B) to have the least amount of time with the battery sitting at 100%. Thanks Timewellspent, hopefully we'll get to the bottom of this. Quote Link to comment Share on other sites More sharing options...
muzicman61 Posted April 1, 2019 at 07:45 PM Report Share Posted April 1, 2019 at 07:45 PM A slight correction to Jeff's first post. I only recently started tinkering with custom profiles. My original default profile was modified I believe using the touch screen in the vehicle. According to the owner's manual the vehicle may not begin to charge if a value profile has been set and will wait until the value charge time to start charging. However it is on the MyFordMobile website in the FAQ where it mentions it will always charge up to 10% after first plugging in. Still a mystery. I would prefer my car wait until the value charge time as I have a special Electric Vehicle energy plan with my power company that kicks in at 11pm.

muzicman61 Posted April 2, 2019 at 03:43 PM Report Share Posted April 2, 2019 at 03:43 PM Interesting update... I've always set my default value charge to the same hours as my cheap rates for my EV Vehicle electric plan. 11pm to 5am. Over the weekend I had an idea. Perhaps my vehicle doesn't think 6 hours is enough time to charge the vehicle and thus starts charging immediately for about an hour. So I extended the charge profile by 1 hour (11p to 6a). When I got home from work yesterday with a completely depleted battery (no more EV miles) I noticed it did not start charging. According to MFM, it started charging at 11pm and charged for 5 hours to 100%. I'll monitor it this week and see if it exhibit the same new behavior. jsamp 1 Quote Link to comment Share on other sites More sharing options...
jsamp Posted April 4, 2019 at 04:45 AM Author Report Share Posted April 4, 2019 at 04:45 AM That is likely why it was charging at plug-in before. I know when you use Go Times it will adjust the start time if it thinks there is not enough time in the charging profile to get to 100% by the go time. We may have solved this one, however that doesn't explain why the MFM website says the 10% charge thing. I've never seen it do that. Quote Link to comment Share on other sites More sharing options...
muzicman61 Posted April 7, 2019 at 04:19 AM Report Share Posted April 7, 2019 at 04:19 AM Well I think it is safe to say that the charge window was the issue on why my vehicle started charging immediately. Apparently it thinks it needs 7 hours to charge so by changing my profile from 11p to 5am to 11p to 6a, I no longer charge when I first plug in. That being said, I did find a bit more detail on my ford mobile website.. The vehicle overrides the Value Charge Profile if the State of Charge of the traction battery is less than 10%. After the vehicle charges up to 10%, it will delay the remainder of the charge until the lower-cost times selected in the Value Charge Profile. So now the question is... what is the traction battery? Is that the high voltage battery? Quote Link to comment Share on other sites More sharing options...

Is that the high voltage battery? I'm guessing here, but I think the 10% thing is relative to the entire 7.6kWh HV (traction) battery. So if you are deep into hybrid mode, you could be below 10% charge (.76kWh). In that case, when you plug in it will charge to 10% (which is still in hybrid mode) and then wait until your value charge profile. Below 10% is dangerously close to bricking your battery, so they want it to get above that for breathing room while it sits waiting to charge.

jsamp Posted April 8, 2019 at 02:35 AM Author Report Share Posted April 8, 2019 at 02:35 AM Hypothesis confirmed. Just so happens that my wife drove the Fusion today, so it came back fully depleted far down into hybrid mode. So I put it on value charge to start tomorrow morning, and plugged it in. It did the light cycle, then turned off. An hour later I checked, and it had filled up to the top of the hybrid portion and said "0 miles" where it had only shown a nearly empty hybrid battery before. So even though it said "waiting to charge" it was still adding to the HVB. Seems to have gone beyond 10%, but it did charge none the less. jj2me and muzicman61 2 Quote Link to comment Share on other sites More sharing options...
muzicman61 Posted April 8, 2019 at 01:29 PM Report Share Posted April 8, 2019 at 01:29 PM So even though it was charging the light ring did not pulse as it usually does when charging? Quote Link to comment Share on other sites More sharing options...
RickEnergi Posted April 8, 2019 at 10:23 PM Report Share Posted April 8, 2019 at 10:23 PM (edited) We just experienced a similar issue today. Car returned home around 3:30, as it always does, totally depleted. Wife plugged it in. Charging is set for 7PM. Ring was not lit, not did website or app indicate it was charging. Went into garage around 5:50 and heard fan running. Unplugged car, fan stopped. Facts:- to get to 10% battery doesn't take over 2 hours. So it wasn't charging. - it's 70 degrees out. Shouldn't require 2+ hours of cooling, and if it did it should cool without battery. I'm annoyed. I don't want it to charge until 7PM. I do know that they rolled out a new backend recently, but have no idea what they changed. In short, Ford's software isn't great. Their support of the software isn't great. We only bought the Energi over the Hybrid due to its lower cost - otherwise we wouldn't have bought it. When the lease is up I plan to sell it, and will be hard pressed to buy another Energi-Ford, should an SUV exist with adequate capability, unless they've made some big strides.

jsamp Posted April 9, 2019 at 07:34 PM Author Report Share Posted April 9, 2019 at 07:34 PM I don't know that I've ever had my car plugged in where the cooling fan was NOT running. Maybe I've just never noticed, but whenever plugged in, I've always heard the cooling fan running. Maybe it shuts off at late at night, I dunno.

jsamp Posted April 9, 2019 at 07:36 PM Author Report Share Posted April 9, 2019 at 07:36 PM So even though it was charging the light ring did not pulse as it usually does when charging? Correct. It did it's cycle (2x) then went out. Quote Link to comment Share on other sites More sharing options...
muzicman61 Posted April 10, 2019 at 03:51 PM Report Share Posted April 10, 2019 at 03:51 PM Rick... they due seem to have a mind of their own and agreed the Ford software has room for major improvement. But I still love my Fusion Energi. I'd suggest setting MFM to give you a notification when it starts and stops charging. Then check how long it takes to charge. That should tell you if the car is actually charging when you first plug it in. Make sure your value charge or default profile charge is 7 hours or greater (7pm to 2am at least). See if that makes things any better. Quote Link to comment Share on other sites More sharing options...

See if that makes things any better. I do. When we plug in the car at 3:30 ish, and you check the app, it says it will start charging at 7PM. It's done charging well before the end of your value charge period, which is 7PM - 11AM (peak is 11AM - 7PM). My point is that it should not be using electricity before then unless it tells me.

muzicman61 Posted April 11, 2019 at 04:08 PM Report Share Posted April 11, 2019 at 04:08 PM Rick... do you have multiple charge profiles by chance? If so, delete all them and then setup the default to the hours you want. If you only have the default then I don't know what else to try. But definitely turn on the notifications for start and finish charging. Quote Link to comment Share on other sites More sharing options...
RickEnergi Posted April 11, 2019 at 05:54 PM Report Share Posted April 11, 2019 at 05:54 PM (edited) Notifications are on. Car knows it's HOME. Shows ready to charge at 7PM when the Value Charge period starts. We've gone into the garage a few times between when it's plugged in and the start of the Value Charge period, and have not caught the fan running again. Wild guess is that the temps were close to 70 that day, and not since, so it hasn't been running... Of course one could ask why the fan isn't running without the car being plugged in IF the car senses the batteries need more cooling...

gsxrboi600 Posted April 12, 2021 at 08:33 PM Report Share Posted April 12, 2021 at 08:33 PM I'll unplug the charger from the car if it starts charging right away at home when it isn't supposed. Usually after a couple tries, it works properly for me (where it waits for the value charge schedule to begin charging). Hope this helps.

jsamp Posted April 14, 2021 at 05:43 AM Author Report Share Posted April 14, 2021 at 05:43 AM That post is from 2 years ago. I think he's figured it out by now. Typically when I see the behavior you describe I watch it for a minute or so and inevitably it will self correct and flip over to value charging and stop charging all on its own. No need to unplug-plug several times. It seems there is a check cycle the car does every minute or so, and then realizes it is not in the value charge time schedule. jj2me 1 Quote Link to comment Share on other sites More sharing options...
