Slow charging with Autel 50A [Fix= replace SOBDM]

[kcoates2]

Did you check the Autel app to see if the output current is set to 40 or 48?

The app and the selector switch in the charger are both set to 48.

Oops. I knew that, I don't know why I got it backwards in my post.

For DC it’s the opposite, the truck tells the charger it wants 500A and the EA charger laughs and says you‘re lucky to get 100.

The app and the selector switch in the charger are both set to 48.

What does the charging curve in the app look like? Has it ever gone over 3.7kW? That will show you the voltage and current measured in the Autel unit.

In case a similar issue happens to anyone else, here is an update and how the issue was resolved by Ford:

On 9/13, I had a service appointment at my local Ford dealer to troubleshoot the issue. They performed tests on the battery packs and the related systems and the truck was diagnosed to have a faulty secondary onboard diagnostic module (SOBDM). It took them a week to get the part and perform the replacement. I received the truck back on 9/20 and so far so good (fingers crossed). I can now charge at home with my level 2 Autel charger and it is performing correctly.

Thanks for the update!

Thanks kcoates2. How did they diagnose it? Did you have any error or service lights on your dash indicating a problem?

I ask because I just got my truck back after they replaced an array due to a faulty cell and I immediately experienced a similar issue as you, but with with my Ford Charge Station Pro. I could once charge close to 10% an hour, however it recently took me 9 hours to charge just 18%. DC charging seems to work just fine though.

I look forward to your response as it might help provide some guidance for the crew at my dealership.

When I first tried to charge the truck on a level 2 charger, the truck faulted and the wrench icon appeared on the dash. When I tried it again, it faulted again, but no wrench. When I called the dealer, while on the phone with the service advisor, he was able to remotely see the codes the truck was throwing. From there, we scheduled the service with a hunch that the truck was having an issue with the AC charging, especially since I was able to use DCFC to charge. If it would help to show what the technician did to diagnose, let me know and I'll be happy to post it here.

Thanks kc. Anything would help at this point as my dealership is claiming they can’t find anything wrong, however I’m only charging at 2.8 kw.

 

[kcoates2]

I was also charging right around 3 kW before the truck was fixed. Here's the info from the the paperwork the dealer gave me after the service was complete. It mentions code P0D67, which may help your dealer if they hook it up to an OBD2 module. I hope this helps them get to the bottom of your issue.

Thank you sir. Much obliged

Thank you sir. Much obliged

Good luck!

Turns out it was the SOBDM needed to be re-“PMI”ed, which worked. I’m sure someone with more knowledge can articulate better than I, but the jist was, break the module down to factory, then update.
Hopefully this helps anyone in the future,
Cheers
