Mercedes EQA Charge Anytime issues resolved?

thank you. is there any particular charger that is best?

I’m of the opinion that ‘it depends’. There are some considerations such as if you have solar PV then the choice is restricted - otherwise Charge Anytime can’t determine where the charge emanates from. 
You should also consider your internet connection strength and look at a wired connection if in doubt. 

Thank you for your detailed reply! I was considering the hypervolt charger as it’s wired, however I noted that this is also on a trial 

It is although it has been in ‘action’ for a few months. 
 

If you’re in any doubt on any point then the tech team are available chargeanytime@ovoenergy.com 

Hey @shah84, 

Congratulations on your new EV! I added a badge to your profile to show that you’re now part of the EV club 🎉

 
It looks like you’ve received a lot of useful advice so far! We were fortunate to have @Blastoise186 and @Peter E in the office for a visit, and they got to see one of the new Hypervolt chargers on the day they were announced. 
 
There are always a few things to consider when installing a charger, like cable length, whether you have or will consider getting solar power in the future, and whether you need to connect via ethernet or Wi-Fi. 
 
@BPLightlog has already shared the article I put out for them and provided the email address for our Charge Anytime team, which is more than happy to answer any questions. You can also call them at 0330 175 9678 (Option 1 new customers/Option 2 existing customers).
 
Please let us know if you have any further questions or need support! 

The issues of charrging EVs is complex. SpeakEV is a good forum to go on (if you are not already) as there will be other people in a similar situation.

The consensus appears to be to control the car not the charge point (CP) This is because the car then knows what is expected of it whereas controlling the CP the car is suddenly presented with a charging situation it wasn't aware of and at some point the power will suddenly disappear and it may cause the car to consider that the CP is now faulty. Cars not expecting to be charged can also go into a deep sleep and presenting them with a charge signal from a CP won't wake them up so they won't charge. Some CPs ‘pulse’ the car to keep them awake but that drains the traction battery so charging is less efficient.

The software in cars is more stable and professionally produced and managed than CPs. There are many cases where CP manufacturers (often quite small companies) have not tested software changes against all cars and you end up with a non-working CP. CP manufacturers certainly go bust more often than car manufacturers and at best you will be left with a dumb CP.

With a dumb CP the car can also draw power under exceptional conditions. I came back from a short trip at -9C and on connecting a dumb CP it immediately took 1kW for an hour  to warm the battery up even through no charge was scheduled at that time.

I thought that choosing the car was difficult enough but turned out to be a doddle compared to choosing a CP. If you are adding solar and battery to the mix then all I can say is I hope it turns out well.

It’s a little more complicated with Charge Anytime as OVO allow either a compatible EV or a compatible charger. 
If charging via a compatible charger (and also if using a system with solar PV) it is important to connect via the charger and not the EV

Hello, 

Please can anyone help. I have just got a Mercedes EQA 250. I have connected it to my home internet but just dont know what else to do on the car to get this to work. 

Really stressful :(

Hiya ​@paularang !

Sounds like you need to enable location services in the vehicle. Did you do that yet?

If you’re struggling to do so, try 0330 175 9678 Option 2, otherwise please chat with your Mercedes dealer or Mercedes customer service.

Charge Anytime app, still not resolved the issue with charging Mercedes. App still defaulting to 50% max charge, therefore I’ve had the delete app loosing lower rate credit benefit.
 

When are OVO going to sort this as it’s been going on for ages!

Octopus are looking a better option for cheaper EV charging.

Not a bug - technical limitation due to how Mercedes works.

The 50% limit gets automatically raised to 100% during active charge sessions as it’s the only way OVO can start/stop charging. It’s kludgy, but it’s the best OVO can do until such time Mercedes provides a better method.

You won’t get any better elsewhere either - Mercedes imposes this limit on ALL smart charging setups.

Blastoise186 - I beg to differ there, active charging makes no difference the app continually defaults back to 50% regardless and I have to continually reset every 5-10 minutes which means if I want to take advantage of low rate overnight charging I’d have stay awake all night just to charge my vehicle 

I have deleted the app as previously stated and now charging fine. Although at the higher tariff 

I never had a problem with my previous Mercedes as it would charge to whatever % set on the vehicle and using the charge anytime app. 

As far as your comment regarding other suppliers…… how would you know?

Morning ​@Tonymuruk and welcome to the OVO Forum. I’ve applied the EV ownership badge to your Forum account.

I can see ​@Blastoise186 has given you correct advice here. Here’s an article that explains everything in more detail:
