Failed AUTEL Charger Firmware issue / Workaround.

[Flying4Fun]

For those with a Autel Maxi Charger (and I assume similar models from them) there is a bug in the current firmware that stops the charger from working properly in some circumstances. I ran into an issue and here is a summary of what the issue is, the work around, and potential resolution time.


I Called AUTEL, they had me do some trouble shooting to restore charging function of the charger, such as remove the car profile, and reboot the charger. After which the Macan EV started charging! tried a few times as a double check, and everything was back to normal.

In discussions, AUTEL said they upgraded the firmware from 1.36 to 1.38 a few weeks ago and they have had been getting reports of this charge issue with this firmware version. They indicated that over the next few days a new update will come out to correct it.

The work around seems to be to remove the car profile, and reboot. But he did say if it happens again to factory default the charger and re initialize the charger without adding a car profile and that should allow it to work until they update the firmware

The at issue firmware is:
Charge Control Module 1.38.00 (1.36.00 was the prev version working just fine - I have auto updated enabled)
Power Control Module 1.20.00 (don't know the prev version or if it changed, but the issue seems to be in charge control module)

Not sure how many people use this charger with the Macan, but thought I would share this in case it helps someone out.

I replaced our Autel EVSE. It would "forget" the time zone, and change from Pacific to Eastern (default?) randomly, resulting in charges starting 3 hours ahead of schedule at the highest cost/kWh.

No way to know other than watching it, which I got tired of doing. Replaced with a Chargepoint home flex, and not a single issue. It's our 2nd Chargepoint.. FWIW.
