Mercedes max. charge level discussion- Any workarounds?

I have read through some of the forum topics and it is well-documented that Mercedes and Indra/OVO has an as yet unresolved problem, that being the maximum charge level is re-set to 50% by software Gremlins.

I wanted to start a dedicated forum topic about this issue and keep it going until it is resolved, because this is not a minor inconvenience. It would be THE reason for me to not have ordered and signed a finance engagement for a Mercedes EV, or paid over £1000 to OVO for a charger. In my circumstances, charging at home is a key reason to have an EV. Without that, I would go back to a diesel tomorrow.

I will update the thread when Mercedes replies to me by email, now that I have been able to pinpoint the issue for them. So far (before I knew there was a big problem), they have replied quickly but with the generic “reinstall the Mercedes Me app - send fault logs - what phone are you using” etc etc etc.

So, I invite you to write your workarounds (if there are any), your communication with Mercedes and any other useful info on this topic to help other Mercedes EV owners live with this extremely irritating problem.

Hey @NikB,

 

This was the last update I received from the team:

 

Its a known issue with Mercedes still being in the Beta testing phase unfortunately. They are still working on it.

 

In order to stop a charge on Mercedes vehicles, we set the in-vehicle max state of charge to 50% which then shows in the Mercedes vehicle and app. To start charging again, we change the in-vehicle max state of charge back above 50% to the desired level. Unfortunately we are seeing that the increase from 50% to 100% state of charge isn’t being applied reliably on the Mercedes app.


If plugging in when the vehicle is under 50% in the afternoon/evening, we’d advise a workaround of checking the Mercedes app before you go to bed and manually changing the maximum state of charge back up to 100%. This should ensure the vehicle is charged correctly by the ready by time. We appreciate this isn’t ideal, so we’ve got our developers working on a solution to ensure reliable charging in the future.

 

 

There may be some more advice on the above topics. 

 

To update all Forum Members who are part of the Mercedes / Beta Pilot:

 

This is still a pilot, and some issues - like the 50% total charge problem - may take time to resolve. As a result, the Charge Anytime team is unable to provide further updates at this time.

 

If the limitations you're experiencing outweigh the benefits of the Charge Anytime add-on, we recommend leaving the pilot for now while we work on improving the service.

 

We’re sorry for any frustration this may cause. Please keep an eye on the Forum for updates - we’ll share any new developments as soon as we have them.

 

You can exit the Mercedes Beta Pilot at any time by taking the following steps:

 

  • Open the OVO Charge Anytime app
  • Click on the "Account" tab in the bottom right
  • Click on the User icon in the top left
  • Click the "Delete account" link
  • Select a reason for leaving and click "Continue"
  • Your app account will now be deleted and there will be no further connection or interaction between your car and the OVO system
  • Note: You will still be credited for any smart charging that you have done up to this point

Hi @Sarah7777,

 

Have you been able to get in touch with the Charge Anytime team about this yet?

Just got my EQB this week (Indra charger installed by OVO) and I’ve been struggling with this issue, but I think I’ve been given the solution after a call to OVO’s ChargeAnytime team.  I had installed OVO’s ChargeAnytime app and registered my car there as instructed, but that seems to be the root of the problem.  There’s some instability with the Indra charger, the car and the app all in play.  They advised that I deregister my car from the app; delete my account from the app; and then delete the app.  I can manage the charging schedule via the Indra website and the car charge level from the car itself of via the MercedesMe app. 

I’ve done all that and so far so good!  The car is happily charging beyond 50% and towards the 80% max charge target.

    Hi @andyeff , I think you are spot on with this. I have an Indra charger linked to Charge Anytime, and have had no difficulty charging a friend's EQA when they come and visit. We simply set the EQA to whatever charge level is needed, and let the Indra web app do the rest.

    The problems seem to arise if people try to link the car to Charge Anytime, rather than the Charger.

      This is correct. You need to make sure that only one or the other is hooked up - never both - otherwise you will experience issues.

      If both are compatible, we generally recommend you use the Charger route as it’s usually a bit more reliable - and lets you use ANY EV with it! :)

        I’ve been on Anytime  with my EQA for a year now (Pod point non compatible charger) and never had a problem of it not charging to the amount on the anytime app. after reading on here about this issue of the Mercedes app changing to 50% I started monitoring it & sure enough it dose change and stop at 50% but later in the night it always carries on to what I’ve set in the anytime app. Try to just ignore the Mercedes app and don’t try to change it. Anytime will sort its self out

          Hey @Chris78 

           

          Thanks for coming on here with that advice, it’s always good to here it coming from community member’s own experiences. As you’ve said, as you’re connecting through a compatible EV you only need to be using the Charge Anytime app and it’ll charge by the ready by time set in the app. Using any other EV or charger app at the same time may cause issues with charging.

           

           

          For anyone setting up Charge Anytime with a compatible charger instead of EV, this will be different and we’ve got a handy topic all about how to set up a compatible smart charger with Charge Anytime:

           

          Thanks again Chris78 for popping on with that advice, it’s very much appreciated!😊

          Unfortunately this is still an issue. I have a brand new EQA with charge anytime linked via the Mercedes App. I have attempted to fully charge my car about 15 times now. The maximum I can get is 50% due to the known "Gremlins". Following so many unsuccessful attempts I then tried to change the maximum discharge on the mercedes app it immediately changes it back to 50% and stops the charge. The only fix I can find is to issue an urgent charge which defeats the point of charge anytime.

          Don’t mess with the settings all the time! Just set it to your desired level once and leave it be. This is intentional behaviour right now because of how the integration is forced to work - Mercedes doesn’t exactly have an amazingly elegant way of making this stuff work compared to other EV manufacturers. During an active session, the limit will raise to your preferred level to enable charging to run.

          If you need more advice, call 0330 175 9678.

            The issue is this aspect is not happening. Just seems to lock in at 50% and remain at that level the following morning. I will try calling the number.
