2021 MS Chademo issues

[KevinY]

My chademo adapter doesn't work on my new S, anyone else have this problem?
Car doesn't communicate with the charging station.

Can you try 1 - 2 different charging stations? If that doesn't work, you should schedule an appointment through the Tesla app.

 

[KevinY]

The service centers can perform a firmware update to the adapters. Mine was purchased in 2017 and has never been updated. That's why it didn't work with the new vehicles.

Two friends of mine have tried charging their new Model S Plaid with Tesla’s CHAdeMO adapter and it doesn't work.

I believe it might be related to this firmware update.

Did you tried updating yours? Did it work?

Do you know if you can do the update remotely or only at service centers?

Ya I spoke too soon, an update and even a brand new adapter didn't work. I even have a CCS adapter and it doesn't work. Tesla reached out to me and they are aware of the problem

Do you have any updates on the issue? Has Tesla solved it for you?
The CCS you tried was the Korean one? Did you have the 2021.40 or later software version on your car?

I've got 2021.44.6 and just tried the Chademo and a Volta DCFC with a Lectron CCS adapter and neither work.

Oh, the Lectron CCS uses the same protocol as the CHAdeMO adapter... So if the former doesn't work, the latter wouldn't either.

I believe Tesla might be counting on their new CCS Adapter moving forward, sou they might have ditched CHAdeMO support for new cars altogether.

Have you taken your CHAdeMO adapter to a Tesla Service Center for a firmware update, as some people have suggested? (They were talking about the internal firmware inside the adapter, not the car software)

Yep I have two chademo adapters. One from 2017 and 2021. Both were updated at the SC in October.

I don't know if this will help, but I plug the Chademo adapter in to the car first, then close the doors and lock the car with my fob. Then I connect the Chademo plug from the charger and activate the session from the charger and that works for me just about 100% of the time. I have a 2013 S and a 2018 3.

On my refreshed S, I could charge via the ChaDeMo when the SOC is low. Today, it worked when SOC wss 22% at start of charging. It stopped charging at 49%. Charge rate was 40 KW. Running 2022.8.

Some 3rd party charging stations only support 30 minute sessions, so it may have timed out?

No, this DC fast charger is in our company garage for employee use. 75 mins per session.

Have you been able to solve the issue? I have exactly the same. My refresh model S charge only when the battery is below 50% using CHaDeMo. Model Y charges just fine.

No change.
