Charge Anytime - why won't it charge Mercedes 100%?

I just installed Charge Anytime for my Mercedes EQC 400.

I have it set on Min 50% and Max 100%.

My question:

Why can’t it just be set to a 100% charge, or even 95%? I don’t want it to only charge 50%. I’ve tried it twice and all I get the car charged is around 50% but I need the battery to be fully charge for my longer journeys. It’s quite stressful not knowing if I’ll have enough battery or not when I leave the house in the morning.

Is it meant to work like this? Why can’t I just set the % I want it charged at? The highest I can move the Min charge to is 50%. I’ve contacted OVO but they’re not getting back to me.

Thanks.

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 @Katja , the Min setting is meant to indicate a low level for the EV so that it begins to charge if below this on connection.
The Max is often lower than 100% as the batteries do not like being held at that level - your manual should tell you if this is right for your EV.
You should indeed get a higher charge level if you’ve set a ready by time.
Did you email the tech team?

What you’ve probably done is hooked up both the Charger AND the EV to Charge Anytime. You must disconnect one of them - preferably the EV - and leave the other active.

Bad things happen if you try to use both options at the same time.

I did that (only used Kaluza) a few days after getting the car, as the Kaluza people told me not to use the Charge Anytime app, but thanks for checking

@NikB , if you have an Indra charger, you should be using the Indra web portal. Perhaps the information isn’t prominent enough but compatible chargers (which Indra is) should use their own interface which links to your account.

Hey @dharvey24,

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.

If you have any issues with the charging stopping at 50%, you can manually change this through the Mercedes app to continue charging to your desired level. It’s a known issue that the team are working with Mercedes to fix hopefully. When we know more, we will update the thread 😊

this is not true

update today, 1st May 24. Car was 67% charged at around 11pm last night. I set the max charge level to 100%. Moments later, the app reset the level to 50%. At 7am today the car was 90% charged.

So, this is not a complete disaster but it is unpredictable and as reported elsewhere in the OVO forum, a long term issue.

At what point are these products deemed incompatible and not fit for purpose?

This is my first EV and being a so called petrol head, it was a deep consideration moving away from traditional cars. I am deeply disappointed to step into such a mess.

Hi @NikB,

I’m sorry to hear you’re experiencing these problems.

It seems that this is a common issue with Mercedes at the moment. It’s currently being looked into and we’ll update this thread as soon as we have an update on this for you.

I’ve reached out to the team for some advice on this for you. They’ve said that if you start charging on Charge Anytime, plug the car in, then check back into the Mercedes app after it starts charging to increase the Maximum Charge back up to 100%. This has been working for some people at the moment.

Hopefully this helps.

hi - the car now charges to the level i set, but what i do not know is if this is at the anytime rate of £0.07 or not. The problem I now have is I cannot correctly access Kaluza, so I am unable to set charging times which I believe is necessary for the anytime rate to be recorded. i am waiting for the anytime team to reply to emails. The fault is not really with the car, but with Kaluza/OVO
