Hight Voltage Battery overheating during charging on L2 after OTA

[Shayne]

There's no such thing as "urgent" when it comes to OTA's and Ford.

Who's idea was it to drop power-up 6.6.6 before Christmas anyway?

Give it a few months and live with it sucking power such you need 40 amp just to start breaking even as it tries to burn up your batteries. Could be an expense couple of months on the hydro bill if the car makes it. Just can't make this stuff up.

They will not be rolling back as 6.6 is the update that satisfies the safety concern of melting and burnt smells of the charging port. Appears the problem some are having with it charging like crap for months after that update will be put on the back burner now to address this condition if it ever was on a burner at all. Feeling for those hit with this as I understand this is the vehicle that so far requires constant babysitting trying to make it function as described at purchase. Best wishes guys/gals; try to forget about it if you can and enjoy the season. Let it die and have it dragged away is not the end of the world.

which update is suspected to be the problem? 6.2?

It may be something in 6.6.0 and/or the re-released revised version of 6.2.0 (which may be considered 6.2.1).

Today Ford sent an engineer to work on my car which was at the dealership.

In a few hours of work he said he found the error in the OTA received which caused the problem of overheating and loss of energy on L2. He tells my dealer that my car is now repaired and I can go pick it up.

At home, I plug in the car and surprise!

The problem is STILL present. No change.

In only 20 minutes, the battery lost 4%...

So tomorrow back to the dealership.

Very disappointed!

An interesting thing is that the value of “Energy to empty” is ~2kW more than it used to be at the beginning of the charging session.

Well, tough to hear your bad news. Please keep posting. My servicing dealer thinks that the battery heating problem can be solved by updating some software modules. Your latest report contradicts this. I hope your problem is corrected during your next visit. A post describing the remedy will really help everyone else.

Is yours at the dealer now?

No, I called them yesterday to get their thoughts on a fix. I was going to sehedule an appointment this morning.

It looks like I got a combo:
0. Car cannot properly predict when it’ll be charged to a desired level, being on L1 EVSE it guesses that it’ll be charged up within 2 hours when SoC is 70% (no way 3kw equates to 20% SoC)
1. Car loses charge while “charging” on low power L2 or L1 EVSE’s.
2. Fordpass charging data is erratic at best, car says one state of charge and fordpass will show different one
3. Car won’t stop charging at SoC level you set (was set to 90% and went beyond that)
4. Car won’t charge to 100%, sometimes it hangs on 99% SoC for a few hours, after plugging out it will switch to 100%.

Hey there, Al! Can you please send me a PM with your VIN and dealer name/location so I can look into this charging concern for you? To send a private message, just click on our username and select "Start Conversation". I'd be happy to see what I can do to assist!

They updated 3 modules on mine and it did not help.

Sorry about your lack of progress. Now I know a little about what doesn't work, anyway. You see, my servicing Ford dealer believes that the problem will be solved by software updates, too. I need to come up with a different approach to get this problem resolved. If I get any ideas for a solution, I will let you know.

It was working before, software caused the problem, which means there is a chance software can reverse it? Only thing is if a module is now corrupted and can not be re-flashed than hardware may come in. Bang OTA Christmas eve ................ we are all pulling for you guys.

Thanks for the sympathy. If an OTA fixes the charging problem, then bravo. If the problem can be fixed (and verified fixed) by one visit to a dealer, that's OK.

What's not OK is that there is no OTA and the dealer fails to fix the problem through module updating. Then, I may as well be riding a bicycle in the snow - lots of work with very little progress.
