90% fast charging software update?

[wattup]

Hello,

Any leads on how to get the update that enables fast charging up to 90% ?

Do I have to reach out to my local Ford dealership?

Thanks in advance!

What is the build date of your car? If it is 9/30/2021 or earlier, you can get 21P22 completed at the dealer which provides the fast charging update among other quality of life improvements. If it is after that, you'll have to call your dealer and see if they'd be willing to do them for you for free, which most won't or you can pay them, but that can be pricy!

Thanks for the update! How do I get to know my build date?

Built month and year is on the driver's door frame

I don't understand this policy. So they don't want to update newer production cars but they'll update older ones? I wish I had know this when I bought the car.

Your guess is as good as mine. They really need to just get all cars on the same software version so they can just do OTAs for all cars at the same time. It seems like with BC going out to Job 1 cars, they're getting close, but now Job 1 cars have more features than Job 2, so hopefully they next get Job 2s up to level with Job 1s and then subsequently get 2021s up to 2022s!

Because the newer ones are up to date far more than the older ones. Job 1 should take priority.

How can you have been on the forum since Jan 2020 and not have seen this answer many times?

They're updating cars produced through 9/30/21. Then they'll add the last quarter. Of course now the recall update may take precedence, who knows.

I'm not entirely sure that now would be the time I'd want Ford to increase the DCFC charge rate...
"Direct Current (“DC”) fast charging and repeated wide open pedal events can cause the high voltage battery main contactors to overheat. Overheating may lead to arcing and deformation of the electrical contact surfaces, which can result in a contactor that remains open or a contactor that welds closed."

Updated 80%-90% charging rate is only 35kW. Up from about 12?
This is quite low comparing to top 120-150 kW charging rate at 10% SOC

Actually, it's more like 44kW. Then 34 at 90%.

Could be SR/ER difference. My SR was 35 kW from 80-85% then I stopped there.

I'm skeptical about DCFC alone being enough to cause the problem. My guess is it's mostly from people flooring it to run max power through the contactors.

I know it's just one anecdotal example, but I've DCFC'd over 60 times. Some of those in 100F temps, then getting right back on the interstate at 80 MPH. Never experience the problem. But I also treat the car like a family car rather than a sports car. I accelerate at a normal pace. I don't floor it (or even come close) when turning onto the on-ramps. FWIW.

Defect rate so far is less than 1%.
One or even multiple of anecdotal examples isn't enough to say that is not the issue.

I did a test on mine (4X) and I got ~43kw all the way from 80-97%.
