Fast charging to 90% - How to update?

[wattup]

Has anyone here successfully updated the software that allows fast charging up to 90% or 95% from 80% ?

How to update the software to achieve that? Is it at dealership?

Yes. If you’re not equipped to do it yourself with FDRS, you can have it done at the dealership (as long as your car was built before 10/1/21).

I had all the updates done at the dealer 2 weeks ago and my fast charging still drops way off at 80%, to 12 kWh.

Also, the EA chargers I use don’t seem to recognize plug & charge. I authorize using FordPass.

I’ll keep trying and someday I’ll be pleasantly surprised.

That‘s a good indication that your dealer didn’t do all the updates.

Thank You! How do I know the build date?

The month and year are on a sticker in the driver’s door jamb.

I had the 21P22 update done at the dealer in Feb, and tested the fast charging right after that, it went to 44kw at 80%. I do not ever go past 80% on road trips, the only exception was once when we were eating lunch and that got to 86%, that happened before the software update.

What's the deal with cars built after that date? Does it just come stock like that or are they not able to change the limiter?

On my side, seems to have these updates to do, do you know which one regards the fast charging after 80% ?

How do I find out what system release update I’m on?

On the Forum, you have some people with FDRS software, that can tell you if you give them your VIN.
generaltso gave me this list regarding my VIN.

I have most of the updates done like 2 weeks ago at the dealer. Yesterday I drove 1400KM or about 900 miles and fast charged like 6 times on the way. The thing that I noticed that at some chargers I hit peak charge speed at 112 KWh (for 1 minute tops), but on average around 80 KWh. After 70% it dropped to 60-70 KWh. After 80% it dropped to about 30-35 KWh. Its kind of an improvement, because before it was 7-9 KWh after 80%.

At the same time a Tesla and an Audi were fast charging with 150-175 KWh for 5 to 10 minutes at least.

I'm not sure what build date started having the charging curve updates installed from the factory. Those updates may exist for cars built after 9/30, but Ford's 21P22 CSP doesn't cover later dates, so Ford won't pay a dealer for the updates on later cars.

I can check what updates you still have available if you want to send me your VIN.

Those numbers (both pre and post update) are below what we experience in the US.

Prior to the update, at 80% it dropped to 14kW. After the update, from 80 to 90% it's around 44kW. At 90% it drops to around 34kW. I verified this on a recent trip where I charged to 95% to make it home on a 197 mile leg.
