Charging more than 91 kwh?

[ufovideos]

Looking for some help in second month of ownership.

I went to check how much energy I've used charging at home so far this month... and this doesn't seem possible. Added 277 kwh on a charge? To a 91 kwh battery?

Am I misunderstanding this?

This is way more electricity than it used in the first month. If I'm doing the math right, this is like $150 of electricity, I used about 12 bucks my first month.

Is this likely an issue with the app or the car or the charger?

Could it be the lojack?

23 California Route 1, using the 240 mobile charger.

thanks in advance if you've also had this issue or have some advice.

The app is horrible at counting up the kWh used to charge. Known issue. Some third-party EVSEs have the ability to track usage. Or you can install something like an Emporia Vue whole-home electrical monitor and use one of the individual circuit monitors to monitor your EVSE.

There are better ones available, but this one does the trick for me.

I’ve found that FordPass often loses track of the decimal point - so 245 kWh is really 24.5.

You can estimate the charge level using the EVSE’s report. You should expect to see the in-vehicle charge to be about 7-10% lower than what the EVSE reports.

Looks like you lucked into a super-sized battery pack!

I monitor my Autel app that seems to be more accurate since it will measure the total including any loss while charging and I don't pay too much attention to the FP app.

Click on any one of those individual charge history entries. A "Summary" page will pop up. On that summary page, you will see "Charge" represented as a percentage. Multiply that percentage by your battery size (91 kWh in your case) and you will obtain a kWh usage amount that is accurate. Before the app transitioned to show kWh vs. percentage, that is the way I computed my electricity usage. Apparently, it is still the best way to do so given the erroneous readings shown on the "Charge History" page.

I was freaking out that it was discharging and recharging a huge amount of power each time but this makes more sense. Thanks.

Yes, but what I was worried about was that it was discharging and recharging a huge amount of power each time but this makes more sense that the app just doesn't give a very accurate number. Thanks!

If only Ford had a computer to figure out math problems. However programmers don't seen to know the difference between HVB and 12v. Thus ford.com says HVB% but actually mean 12v%. I've heard in computing inputing wrong numbers gives wrong answers. I could be wrong though.

This is not correct. Ford’s nomenclature says “Charge Level.” It does not indicate where this level is coming from. Based on the fact that the majority of their customers are ICE, the UI architects likely left off the four characters “12V “ at the beginning of the nomenclature. While it is vague, it is not incorrect. From the point of view of an ICE customer, it’s probably not confusing. From a BEV customer’s point of view, yes it’s confusing, but it’s not posed as a representation of the level of the HV battery pack. ?‍?

I stand corrected. Thanks for explanation, it actually now makes sense. Sometimes an explanation actually makes me change my mind and understand why. Thank you!

While I am new to this forum and maybe totally off base, I think that the app is simply multiplying the time on the charger (number of hours) by approximately 7 (kw/hour of the charger) weather or not actually charging all those hours (ie. after max. charge setting has been reached).
If I only charge say from 40% to 70% then disconnect my charger, I find the indicated energy added to make sense. But when I leave charger plugged in for say 24 hrs, the app shows approx 24x7 kwh added (168kwh). I think the app has no way of knowing the efficiency of the charger so gives us a dumbed up version of time on charger and energy per hour. Just my thoughts. Am I wrong?

That does sound like a big jump in energy use for your second month. It could be a glitch with the app reporting incorrectly or maybe something with the charger setup. I'd start by checking if the charger is working as expected and if there are any settings that might be causing it to draw more power than usual.

Right. It's not just the power usage, it's that it's saying it's charging over 90 kwh, which isn't possible, unless it's somehow draining and recharging the battery while it's plugged in. It sounds like the most likely answer is that the app just isn't very good at tracking the actual kwh charged. What does your app look like?
