Charging issues

[Rosie60]

I've had my ID3 for two months. For the first five weeks I charged with a 3pin plug charger. Overnight it added 13%. I then got an OHME installed which proved to be faulty with incessant tamper messages and a failure to charge to 80% and finally failing to charge. My new OMHE replaced was set to charge for the first time last night 49% to 80%. It charged to 65% and I received 2 messages from the charger.
Charging Error
Your car is charging slower than expected! Is the battery full? Please check your car!
Charging Error
Your car stopped charging unexpectedly! Is the battery Full? Please check your car!
My car said
Unable to fully charge vehicle. Please check your vehicle wallet

Despite a search through the online manual I can't see how to check the wallet
I've also realised that the car has never charged more than 13% except once when it managed 23%
I've not ticked any charging instructions on the car. The battery care mode is on and charging is set to 80% ( it has never reached 80%) I've booked it into VW next week. Anyone experienced anything similar?

The vehicle wallet is just a silly name for the electronic handbook.
More information is needed really to help you possibly diagnose the issue.
What happens if you plug the car in with no schedules? Turn off all the smart features in Ohme, or tell it to do a max charge. Tell the car to charge immediately. Does it charge at 7-7.5kw, or some reduced rate, or not at all? (You'll be able to see in either the Ohme or VW apps).

Am I correct that your charger is untethered? If the latter, is it possible you have a faulty cable or has it worked elsewhere? The cable seems an obvious candidate to me if you were using the same one with your first charge point.

Have you ever charged away from home? If so, what happened?

It's worth peering in the chargeport with a torch and trying to remove any debris you can see. Excessive grit or dust in there can be a problem.

It's charged ok away from home. It could be the cable. I hadn't thought of that. I did an 1 hour max charge which gave me 4.3kWh. The replacement charger thinks the battery is full when it's not (charging from 66% it only took it to 72%.). I will take the charging cable with me to the garage. Thank you

4.3kwh in one hour doesn't sound normal - did it charge at 7kw and then stop, or was it charging at a reduced rate throughout?

[Rosie60]

I’ve just tried max charge. It started at 0.56kw and settled at 3.76kw, which doesnt seem very high. There are no other electrical items running in the house. Also the actual battery charge showing on the app hasn’t moved from the original 72%. The smart meter display shows usage at 3.82kw. The VW app suggests an increase of 1%. Not sure what any of this means

There are some settings in the Ohme App which might be worth having a look at although if you did the Max charge it would ignore the Dynamic charging setting at least. May be worth seeing what the VW App says when charging although "Unable to fully charge vehicle. Please check your vehicle wallet" suggests a fault with the car. Possibly something with the Octopus tariff?

I get loads of errors throughout the night (I had to silence the notifications!) as the Ohme starts and stops, like your first two:
Charging Error, Your car is charging slower than expected! Is the battery full? Please check your car!
Charging Error, Your car stopped charging unexpectedly! Is the battery Full? Please check your car!

but I don't think I've had the "Unable to fully charge vehicle. Please check your vehicle wallet" message.

You can also find the online manual here if you have a note of your VIN https://www.volkswagen.co.uk/en/owners- ... nuals.html

Thank you. I’ve searched the online manual and can’t find anything about the wallet. I shall see what VW say on Wednesday, and I’m taking the charging cable with me.
I see you are getting similar messages, but does that stop your battery being charged to the preset level?

[Fry]

Although I get the error messages it’s never been an issue getting to the charge level. I have OVO which means that it schedules all through the night and starts/stops whenever it wants.

I think as sidehaas says, the online manual is actually the wallet.

Hopefully VW can help

On Max charge it should go to 7kw, so you definitely have a problem. Hopefully VW find it for you, good luck!
If you haven't ever had a successful charge from this charger, it is also worth double checking the charger installation. Maybe drop Ohme customer service a line and ask if there is a way to be sure the problem isn't either that the car has been incorrectly set to 16A (3.5-4kw) or that the CT clamp hasn't been installed correctly.

The online manual IS the wallet.

Are you sure you have a 32A cable?

[Up the jumper]

I had a similar issue with a replacement OHME charger. In my case there was a fault with the ct clamp and so the charger limited itself to 16A. OHME Customer service arranged for this to be checked (under warranty) although they weren't the quickest.

I've only done one charge with our Ohme Home Pro since the 3.7 OTA update. The Ohme app (and charger display) thought initial charge state was 0% when it was 30%, and throughout the charging session claimed a charge state around 30% below actual. The car stopped charging when it reached its 80% limit, leaving the app and charger confused at being unable to deliver the rest of the expected charge session.

I'm hoping the app and charger resynchronise at some point, but it suggests Ohme's idea of state of charge could often be estimated rather than actual. If the estimate is too high, the charger might reduce the charge rate to deliver the target charge state at programmed end-of-charge time?

Ohme always assumes the car starts at 0% if it does not have access to the car's API. It then estimates charge % added just based on it's generic knowledge of how many kwh an ID3 battery should have. This always has a small error in it.
You probably need to re link the Ohme and car after the update, if you want Ohme to know the real SoC. (I always use my Ohme without the API link, and just tell it what I want it to add).

Thanks - I thought that was what was happening. There wasn't an issue for the previous updates. I like Ohme to be aware of actual SoC as it then can adjust charging rate to deliver target SoC close to target time. Although I'm not on a flexible tariff, those who are would want that adjustment to take place taking account of total to be delivered.

My car spent yesterday and night with VW. They reported that there are no issues with the car or the cable. They say they tried it on their chargers and charged it overnight to 81%. Their suggestion is that the fault lies either with the OHME charger or Octopus. So the plan is to try charging it at home again and if I still have a problem then to talk to both. I think I will send them both the same email with screen shots. To be continued ………..

My charger settings suggest it’s max charge is 32A

Are you sure you have a 32A cable?

Yes. It’s just been checked by VW

Thanks having had the car and cable checked and ok’d by VW I’m going to have to look again at the charger. This charger is the replacement, although I don’t think the guy who replaced it checked anything. It’s going to take a few emails to get this sorted
