Battery Charging Taking Much Longer

[Bob OC]

I have a 2022 Mach E GT, and after a recent software update (in part advertised to allow more than one phone to pair to the car), I have noticed that charging from around 25% to 80% takes about twice as long as it used to. I have a 240V, 40 amp charger, and up until the software update, it took around 4 hours to charge to the 80% level. Now it is taking 8 hours or so to charge. Is anyone having a similar issue, and are there any suggestions for resolution? It could be that the software update has nothing to do with the longer charging times, but the longer times are very noticeable. Thanks.

It takes my car about 8 hours to charge from 25% to 80% @32A

Does your charger show the rate at which its charger? Which charger is it?

91kWh battery.
25% is 22.75.
80% is 72.8.
72.8 - 22.75 = 50.05.
Assume 10% loss from wall, 50.05/.9 = 55.6.

Max is 48amps, 11.5kWh. 55.6/11.5=4.8 hours
40amps, 9.6kWh. 55.6/9.6=5.8 hours
32amps, 7.7kWh. 55.6/7.7=7.2 hours

Assuming you are using the Ford Mobile Charger, you are likely remembering wrong.

I have noted slower dcfc over 80% same chager 50kw use to give me 43 from 80 to 90 now has dropped to 32 kw. With the distance between chargers this is not a welcomed upgrade. Only tried once but will try again on the way back. Was really happy now just kind of but at least not 11 I guess.

DC charging and level 2 charging are totally different.

I charged on Friday and when I hit 80% was surprised to see it drop to 36kW instead of 44kW.

Exact same time here.

Understand and when L2 charging I am not concerned about speed at all just noting that recent updates appear to have crapped out our over 80% dcfc also. You have noticed it also is bad news.

Hi there, I'd be happy to look into your Mach-E concerns on my end. Will you send us a message with your VIN and dealership info? I can look into things on my end.

Yes it goes to 100A now when it hits 80% then starts dropping further at 90%. Still 100A DCFC is about 3x faster than a 48A L2 charger.

Do you think we will ever have a half decent DCFC charging curve or is this new pull back here to stay? This thing in a group of its peers is not the greatest. I toke the car in for the above 80% charging update this spring as the cold does something to my car up here. After it was done I could charge 43 KW from 15% to 90% no probs. Now with a recent updated it has drop to 33 KW at 80 and that is at the cars request. Two different charging providers verified. Takes a year to get it to charge better and just months to pull it back. Just sad to say the least. Not appreciated when you just sat there at 45 KW 1:18:24.

Another question I have is why on 50 KW chargers is this car requesting 43 KW? Then averaging out at 45 and never goes to 50? Is 50 just too much for the car to pull? There are Ioniq 5's up here now and they are pulling 50. You would think if you see them charging at 80 90 KW they could at least pull 50 for a bit. And of course do it to 90%. Charger down at a key location now and I need to make 245KM (155 miles) in one run. Do the math at 5F. Huge buffer and can only charge the thing to 80% slowly when you need it does not say it is the best. Think this is what we bought into or is there a chance it may get better?

Coming from a guy that seems to know things. So is that official - a new debated charge curve above 80%? What OTA as that in?

I may be wrong, but it seems like I saw the regular old 43kw last week on an EVGO charger. I wanted to make sure I had enough charge to make it all the way home in one shot so I charged to about 88%.

Was hoping one of the affiliates would pipe in to let us know but no one is touching it yet. Such a beautiful road car until you need to charge it. You would think that charging it at an average of 44.00 KW it would not need to dive to 33 KW at 80% but it does. Is this due to the HVJB and the poor contacts? Not only do they want us to think about it before taking off but for a long time while charging.

Screen shots below of a 50 KW charger and some cars are getting that. This was drove non-stop 312 km (194 m) 100 to 15% so the battery was most likely warm. You can see where the car auto offed and then of course the dive at 80% when it is completely over stressed due to that rapid 44 KW draw.

Would be nice to know if they are working on charging because that 80% drop was not there after the charging up grade but is back and therefore it would be nice to know what software did it or it is a problem at my end. As temp start to fall here it would be nice to have 44 KW to 90% like I had. Was not even complaining that it was 44 was happy it did it to 90%.

Edit: Typo maybe more

Official, no, just my observation.

I'm not sure if this thread is supposed to be about Level 2 or DCFC rates? Make up your minds...
