Issue with AC charging/New CCU fitted (Phase One SE LR)

[skynett]

Okay So I seem to also have this issue, I noticed it in the last couple of weeks, I thought maybe I pressed something in the zappi app etc but sure I didnt. it only charges for like 5-10 mins then stopped.

Booked in for Thursday.

Mine is a 2022 72 Reg SR. I use Zappi and I have SOlar also.

Are you on Octopus Go?

Hmm ... you may be the first (?) with an SE SR to report this specific problem. I think everyone else in this thread has a LR model.

I have an SE SR and thought I'd caught this problem of the failed CCU but checked with a Granny charger and somebody else's wall box and fortunately nothing to do with the car. So it's worth checking with other AC chargers before focusing on the car.
Mine was the Zappi, not faulty but it was losing coms with the (EDIT internet rest of my Myenergy system) and apparently as part of the latest regs, has to stop charging if that happens (EDIT I'm probably miss quoting this a little see #361 for clarification). Mine was stopping and starting, look at the left of the screen shot, looks like solar charging but it's in the early hours of a January morning.

Checks worth doing before you go to the garage (suggest you write up the answers for the technician)

1. Does it DC charge without problem?
2. Have you tried at least 3 AC chargers? (one or more can be a granny)
3. When was the last time you did a balance charge?
4. How long has it worked properly for before you had the fault?

If you provide this, it will help the garage to realise it isn't user error and eliminate some of the checks they might otherwise ask you to do.

It seems CCU's are a rare breed, mine needs a CCU and has been put on 'Back Order', no idea when the delivery of this item will become available :-(

 

[tsedge]

There are two big deliveries coming into the UK in February, first due Valentines Day.

I might be making something from nothing but the two members who have replied to my post, @tsedge and @DelBoy, both have Zappi chargers and are on Octopus Go.
I wonder if it's how Octopus switch the charge on that's causing the CCU to fail, maybe it switches on and off rapidly for a few seconds causing the CCU to give up.

FiferMG4 who started this thread posted that he was with BG. Tsedge said he was on Go (not intelligent) and @DellBoy said he is on standard rate so that does rather destroy you theory.

I'm glad about that as I have a Zappi and I'm considering going to Octopus when my contract ends.

Thanks all I normally do not charge at night during the 1130pm-530am period so I can plug in in the morning to get cheaper rate until 11am which is the maximum cheap rate time I get but I plugged in yesterday night around 1030pm and luckily intelligent octopus came on at the time and I left it to charge for about 1 hour non stop and it didnt stop unlike before when it was slowly charging and then stops so I disconnected and plugged in this morning and it seems to charge okay with no issues at all unlike what I had experienced before.

It was strange I had that experience for a few days and I think I saw some fb post with some issues related to the Zappi charger not working properly when I initially discovered this but seeing others having the issues having Solar and also zappi made me concluded its the same issue, I have not tried DC charging before, but I have now cancelled my MG visit, will keep an eye on the issue for the next few days.

Check the Zappi event log for a day that you had poor charging, if it looks like the attached then there is every possibility it's (EDIT internet coms) related. A good log will have a couple of lines, literally starting charging, finished chrg. You can see the log ONLY ON THE Zappi, not app or PC with MENU, DOWN, PLUS select the day in question. Also if you notice a red light in the myenergi logo (car attached or not) its having a problem, then check the log.

Ours will go for days without a problem then start messing about, often on a damp or rainy day. Our Zappi is a long way away and using the ME proprietary wireless, not WiFi. I now have all the bits to hardwire it with Ethernet.

Good luck

EDIT updated for claity I hope in #361

Just a further educational note, our Zappi has clearly had coms issues for the nearly two years we've had it. It's a 2.0 so no hard wired Ethernet or WiFi, and I only upgraded to V5 software a few days before Christmas in preparation to allow a move to Intelligent Octopus. Shortly after we started having charging problems. The V5 introduced logic to stop charging on coms loss.

You may believe all is well in Broadband land because iPlayer hasn't given any trouble but if your Zappi is the other side of the garage and it's raining, damp etc it may have a totally different opinion regards broadband availability.

EDIT I really didn't mean coms with the internet but whatever device has the incoming CT clamp connected to it.

Did yours ever say charge complete? Even though the MG4 battery wasn't fully (60-80%).

 

[DevonMG4]

@Alex Brumpton Oh there's a question, can't remember for sure if the app had charge paused , charge completed with a tick or some other indication that it had come to an end without reaching 100% but yes there was some tell tale difference to normal.

I knew immediately it had done something unusual as the amount of charge was far less for the duration of hours if that makes sense. In my world on regular Go for instance the car would almost always rcv 24.3 kwh in a 4 hour charge as shown in the ME app. I think one 4hr session I rcvd 11-13 kwh when I knew the car was less than 50% at the start and should have been virtually 100% - so it was short charging.

Now I have known the MG4 get fed up with erratic charging and declare itself done with a charge session when not at 100%. This has been when I've tried solar Eco+ charging. On a fluffy cloud day standing by the car with the sun going in and out, you could hear the contactors in the MG clicking away and after a while it will stop taking a charge even if a huge blue bit comes along. As much as to say - if you keep messing about, then I'm done charging.

The key signature for me is the charge graph in #344 above.

Are you suffering similar?

Yeah mines behaving very similar to yours. SESR too.
It went in for a load of updates in December which seemed to work for 6-7 weeks but then the problem returned.

So now you've got me wondering is it an unstable network connection, as my zappi is WiFi connected not ethernet.

Strangely though I don't have any such network errors in the event logs though. Also, interestingly. I went on octopus intelligent 3-4 weeks ago and if I charge it at say 7:30, it's usually fully charged up before I go to bed and will not get interrupted. But if I set it to charge from 11:30, half the time it has a wobble and only adds 5-10 kWh then stayed charged complete on the zappi.

I'm really tempted to get a 20 m ethernet cable and hardwire my zappi as a test.

IO charge last night, Octopus allocated a window of 23:00-06::00 & 06:30-7.
Checking the ME app about 06:45, so still inside a charge window, Zappi was reporting CHARGE COMPLETE charge added less than 4 kWh.
Looking more recently Zappi reporting charge delayed. Possibly because now beyond charge window? Just guessing.
EVENT LOG (not charge log) not actually showing the charge event.
Red light on front of Zappi.
Chucking it down with rain all night, outside humidity 99% and Zappi mounted on a very wet wooden clad garage wall facing away from the rest of the Myenergi devices. A near perfect blanket against wireless coms.

Other days it'll work fine.

Just to confirm I'm not using WiFi but the older proprietary Myenergi 868 Mhz wireless.

My action ASAP is to hardwire Zappi and Eddi back to the router.

I suspect times of day, car updates, moving to IO are a little random and coincidental.

If you can hard wire the Zappi it would be a very positive move. You'll probably need to drill the back of the case and fit a gland around the network cable to maintain the waterproofing.

How old is the Zappi / did you have to upgrade the software for Intelligent octopus?

Yeah I think I'll have to try hard wiring.

My zappi is a v2.1 and was installed September 2022. I already had the latest firmware when I went onto octopus intelligent. But, this issue was also happening on octopus go. From July 2023.

After seeing you have the exact same symptoms I do, I'm actually confident that it is now nothing to do with the car. It has to be some connectivity problem.

I assume you upgraded to V5 software June/July 23?

Just searched for and found the Myenergi email announcing V5 and urging users to upgrade. It was was dated 18th May 2023.

I only upgraded sometime in December 23 and first saw the problem on Christmas eve and did not upgrade to Intelligent Octopus until 9th Jan 2024.

So I don't think it's a bug in V5 but a consequence of V5, ME support told me that the charge point must stop charging if it looses internet connection. I think, but am not absolutely certain of any of this, that according to Gov.uk that... "The Electric Vehicles (Smart Charge Points) Regulations 2021 is the underpinning legislation" and came into effect "The regulations come into force on 30 June 2022" but then to contradict completely what ME support told me, to comply with regs a domestic smart charger must "continued charging even if the charge point ceases to be connected to a communications network" Of course none of this matters but can be found at GOV.UK.

I have the parts now to upgrade my Zappi 2.0 (and Eddi 1.0) to wired Ethernet and plan to do so ASAP.

Good luck, please let us know if your wired connection resolves it
