Intermittent Charging Issue

Got a weird issue and I'm not sure where to go with it. I have a rolec 32A tethered charger at home and I've been having issues with it (or the car) for the past month. It's been installed for 1.5 years but suddenly my car will randomly stop charging. The charger light on the rolec is still green (which I think means connected and charging) but it's like the car doesn't accept the charge. A good example is last night. My battery level was at 0 miles, just made it home on electric power, plugged the cable in and it said 2h 10min to charge. All normal. Woke up this morning and the charging light was still green so I unlocked my car, the charger clicked off, turned blue and I unplugged the car. When I got in it said 7 miles of range. It always seems to be around 7 miles, or 14-15 if I notice and re-start the charigng.
It doesn't do it every time, it's really intermittent... sometimes it charges fine. And each time I've used the 3 pin plug charger to test it it's charged fine.
I'm really not sure if it's more likely to be the car or the charger :( I don't use public chargers now everyone has started charging for them...

Any messages on the Vehicle status screen?

My suggestions:
- check your charging schedule, check the charging levels set in the system (make sure you know how to distinguish between a timed and immediate charge, and next time start an immediate charge);
- next go and find a public charger and test charge your car. At least, after that you would know where the fault is. If you have a neighbour/friend with a charge point, even better.

Hope this helps

You would get this behaviour if you had a future departure time ticked for a different day that when you left with 7 miles and you had the Limit charging set to 30 or 40%. If you have not tried already try setting a departure time for when you want to leave, or changing the limit charging in basic settings to 100%.

Okay this could be totally my fault then. So... I've had a look and in Basic Settings my "Lower Charge Limit" was set to 50%. I've bumped this up to 100% now. I don't have any departures set but I did until recently... I had a departure for every morning to heat up the car (not needed now it's warm). So maybe that could have been it. Pretty sure it wasn't even charging to 50% but we'll see. Thanks for your help guys :) It's on charge now so i'll let you know how it goes...

Excellent help and advise from fellow members as usual !!!.
Strange how it only does it when plugged into the Rolec & not the Granny ?????.
If it was the settings in the car, you would expect it to behave the same way when plugged in on both Rolec or the Granny ??. Yes - No ????.
Remember, the car is the charger and calls for the charge to suit the settings you have entered into the head unit of the car. The Rolec or the Granny does not provide any charge as such to your car.
I could be wrong here, but shouldn't the "lower limit" be set to zero and the "Upper Charge Limit" be set to 100% ????. Sorry can't check this with my car at the moment !!!

Ok so no joy - it should have charged by now. Went out to the car and the rolec is green (not a good sign) and the car's LED is pulsating green, also hear a whirring. Unlock the car and very briefly the MFD says "charging 10:30 remaining" before it cuts off. Take the cable out and plug it back in and it now says 1:10. It's all very odd :(

That's really weird, but it looks like it is not the settings.

I think your next attempt should be to charge the car somewhere else, and may be use a different cable. How about your granny charger? Can you use that one?

Yeah, I am having difficulty believing it is the settings in the car ?.
Even if you did have some type of "delayed charge" set up in the head unit, which I guess you have not ??.
Then when you plug in the car, then lock it - pressing the TOP button behind the VW charging access door would over ride any "delayed charge" as this is the "Instant Charge" function button. Pressing this button after you have plugged in and locked the car will override any "delayed charge" you have set up in the head unit of the car.
My car is set to "delay charge" every night because we have a Eco 7 duel rate meter. On the very rare occasion I would want to charge in the day, I would plug into the car, lock it, then press the top button which will allow the car to go into instant charge mode. If I am plugging into a public charging point ( which I do VERY rarely ) you have to remember to press the instant charge button or the car will NOT charge because there is a delayed charge set up in the head unit. Unless there is something wrong in the settings of the car, then I am starting to suspect there maybe an problem with the Rolec. As "Todor" as said, you should be able to prove your Rolec by either charging from the Granny or using a third party public charger. If the car charges correctly on the Granny or the public unit at ASDA then it has to be the Rolec or the connecting cable in my book !. If however the car rejects a full charge from them, then I guess the car is the problem.
I had some thing similar with my Rolec when it was first fitted, I would plug in the car and the next morning it had charged either a few miles or nothing at all !!!!. I had been using the Granny unit every night for the last 14 months with no problems at all. The problem was down to the Rolec "tripping" the breaker in the pod at totally radome times of the day or night. It would do it even when the car was NOT plugged in !!!!!!. The problem was traced down to a faulty breaker in the brand new unit, it was replaced by the installer and has been fine ever since. I know your situation is different to mine, but it only goes to show that the pod is not free from it's share of problems.
It's a process of elimination I guess now Mike, please let us know now you get on !!!!.

I've tested with the granny charger a couple of times and it's been fine. Could be a coincidence as the rolec does work sometimes but i'll never know for certain. But yeah you're right... my next plan is to run it out of battery again and take it to ASDA to try a charge there then. I'll probably do that tomorrow evening. Thanks for your help. @Carty is right about how helpful fellow members are on here.

As the granny brick works fine, I am thinking Plan B is to try to find another EV person nearby
a) to try their cable on your car
b) vice versa
It could be your type2 cable from the Rolec has somehow got damaged invisibly ( too heavy a wheelie bin pushed over it ?)
If no one nearby I think I read elsewhere on SpeakEV about a new company loaning charging cables by post, aimed mostly at those going to Europe for a week or, and therefore not wanting pay for a cable they will only use a few times.

The symptom of 10hrs to charge I've seen when for some daft reason I'd set the charging current to the lowest level and crapped myself at the car then not being ready for when I next needed it. Whilst the time-to-charge you are sometimes seeing is only happening on the type2 link, and sometimes, there must be something wrong there physically to cause the car to not drink or to do so at a very low rate of charge.

Good advice from @gladini.
It could be that your cable is damaged. There is a resistor between the PP and PE pins which is detected to indicate the cable rating. If the resistor fails (goes open circuit) then the car will think that the cable you are using is only rated at 6A so will take a long time to charge (?10 hours??)

Hmm yes it does sound like that doesn't it, even explains why it's so intermittent. It would be very odd as it's tethered and always wrapped around the charger out the way so I'm not sure how it could have got damaged. I wonder if the company that fitted it on behalf of rolec would come out and run some tests on the cable if the ASDA test works.

Hi Mike626 - Did you manage to give Rolec a call with regards to the problem you currently have with your pod ????.

I have just found this on the "Q & A" section of the Rolec web site.

Q. - ď‚· What is the Warranty on a Rolec chargepoint?

A. - ROLEC PROVIDES A 3 YEAR WARRANTY ON ALL COMPONENTS WITHIN THE CHARGING POINT.

Here is the link to the page:-

I hope you find this of some use - Carty (y).

You're awesome - thank you. I'll be calling them tomorrow hopefully. Was a bit mad at work today with all this malware stuff going on.

Have you checked your electricity supply? If it is over or under voltage, the car will not charge. My Rolec exhibited similar, was green but the car refused to charge. Plugging in a Maplin 13a tester into the house revealed my supply was running at 265v. I had to report it to the Regional Power Supplier, who confirmed the fault was at the local substation. Once repaired, the car took the charge.
Ah that's interesting! Would have never thought of that... I'll bring that up on the phone with Rolec too. Thanks

Did you manage to get this sorted?
I'm having the same issue but with my granny charger. Have to restart the charger several times until it gets to about 8 miles and then charges all the way through to full. Works ok on public chargers. It did the same when we were away last week at two different locations.

My granny charger failed a couple of weeks ago, it would charge to about 8 miles and then stop. It flashed a red light (led5 from memory) which signified thermal cut out. VW replaced it under warranty and it is perfect now. I also have a Rolec at work which never lets me down so I knew it was the granny charger.

Just an update on my wall charger situation (yes it is still ongoing...). Rolec are being completely unhelpful - they won't talk to me and tell me to deal with the installers, despite the parts warranty being with Rolec. My installers are trying their best but Rolec won't help them out either. Apparently my installers currently have 3 cases with Rolec all for failed chargers and are struggling to get anything out of them. My installers are coming on on Tuesday to do some tests but without any replacement parts as Rolec won't send them anything (or give advise) until they've done a site visit. They are even talking about stripping an old unit and using those parts because Rolec are putting them in such a difficult position (they've stopped installing Rolec due to so many issues so maybe that doesn't help the relationship between the two companies but they shouldn't let that affect me). We'll see what happens on Tuesday...
