The EV is FULL

@Hadrian, your car probably has the charging fault and I hope it gets fixed quickly.

However some simple tests could have localised the fault and, perhaps, resolved it earlier or given damning evidence to the garage. (For example see the case at the end of the thread 'MG4 Spotted'). As other posters have said testing the links in the charging chain would have been useful, particularly as, I suspect, the garage does not operate with Octopus Intelligent Go and may not have your EVSE and cable

We EV Owners are, in some ways, pioneers and I am certain that members of this Forum could educate the dealers a lot. Some dealers might resent this but others will welcome the fact that initial fault-finding had been carried out. And the fact that pointing out that early Trophys suffer CCU failures (search the Forum) might have helped them avoid nugatory tests and software changes.

I note you say that the app declares the EV to be 'Full'. As far as I know the MG4 does tell the EVSE its state of charge, so this must be an estimation by the EVSE/App which could be wrong. (As far as I know, MG has not released its charging API.)
You're right. The Master tech at my dealership is on this forum although I believe he just lurks . He's advised me that he's gathered more information from members here than from MG

Hi, I have a Trophy LR 2023 too and a Zappi2 charger. I also moved recently to Intelligent Octopus Go from a simpler Octopus tariff.
Since this change I have had exactly the same issue you described, ie: Octopus sets up the charging schedule, l wait patiently until the following morning when l find that only about 0.5kWh of charge was added to the car, after which the 'EV is full' message.

I therefore have to revert to manually setting the Zappi to Fast charge the car, which is a pain if you want to capitalise on the Octopus cheap rate periods.

Have you found a solution to this problem?
Just a thought, I'm finding the latest Octopus app sets the default time to be ready at sometime the following evening. Check that you set the ready by time to before you need it. Solved my problem.

UPDATE.
The failure to charge problem appears to have been solved.

The MG 4 was delivered to Frasers of Falkirk on 9 December 2024 and during the remainder of the month, no fault finding feedback was provided to me.

On Monday 6 January 2025 at 11am I visited Frasers of Falkirk and walked into their workshop and asked to speak to the technician who was dealing with my car.
Unknown to me, I was speaking with the Service Manager who declined my request and immediately tried to usher me to the Service Reception.
I was aware that the service reception personnel knew nothing about the technical details of the fault diagnosis.
Fortunately, I quickly realised that the service manager who was indignant and evasive knew what tests had been carried out and I told him that I believed that I had located the fault by using a UK data base.

I explained that the early MG 4 Trophy without the rear windscreen wiper, had a known fault with the CCU which was preventing charging.
The service manager was obviously taken aback and admitted that this was a conclusion which the garage had made and they were waiting approval from MG Technical.

At 2:55pm on the same day, less than 3 hours after my visit to Frasers of Falkirk, I received a phone call from Service Reception to say that MG Technical had approved the replacement of the CCU, the part was located within the UK and would be delivered within 2 days.

On Thursday 9 January 2025, in the morning, I was able to collect the MG 4, having had the CCU replaced and was fully charged.

I had intended to delay this update to ensure that the replacement CCU can cope with the menu of stop/start charging offered by Octopus Go.
Unfortunately, I have only used the car for short journeys and there has been no need to charge.

My advice to anyone with a similar charging problem, is to tell the MG Agent, that this is a known problem and to check out the CCU.

Should there be any other charging problems, I will update this post.

I am very grateful to those of our members who have contributed to this fault finding issue.

It's a pity the MG Dealers don't us "common sense" in asking around!

I have just noticed a post by Arog1354 concerning the charge schedules set by the MG app.
If you are using Octopus Intelligent Go, the charging schedules will be set automatically when you plug the car into your charger.
You MUST ensure that all other schedules, i.e. the car, the charger etc are deactivated although you should set the battery charge level within the iSmart app. I my case I set this at 80%.
If you set charging schedules in any app, it will be in conflict with Octopus Intelligent Go.
 
Once the SoC has come down to, say 70% or lower, do a test charge with the slider set to 80%. (Don't bother with a schedule - just do a charge). If the charge stops at 80% then all good; if not then you'll need software updates.
 
The MG4 was collected on 9 January 2025, having had the CCU replaced and after two home charging sessions it has dutifully charged to 80% without further issues.
I have also ascertained from Frasers of Falkirk theat the only intervention which they made to the car was the replacement of the CCU and there were no software upgrades.
 
I have an MG4 Trophy Long Range, purchased in April 2023.

The car is mainly used for short journeys and is charged at home using my Zappi 2.1 charger from my Intelligent Go account with Octopus Energy.

With Intelligent Go, the charging schedules are created automatically via the wi-fi link connecting Octopus Energy to the Zappi (Myenergi) charger and the car.

The target maximum charge is set at 80% within the MG App (iSMART) and I always ensure that there are, no charging schedules manually set within either the iSMART App,

Myenergi App or the car.

The total charging schedules are assigned by Intelligent Go.



For several weeks, the charger was plugged into the car overnight with Intelligent Go creating three or more on/off charging schedules operating during the night.

Repeatedly I found that the car had received around 0.86 kWh and when the Myenegri App was inspected it was displaying “EV IS FULL,” even when in fact the total battery cargo was 40%.

I had extensive communications with both Octopus Energy and Myenergi as I believed that I was making some error in initiating the charging process.

The conclusion of both Octopus Energy and Myenergi was that the charging system within the car was defective.



I restarted one of the charging schedules and was present when the Zappi started to charge the car.

I observed that the charging initiated and lasted a few minutes before shutting down.

When the Myenergi app was inspected, it was seen to display the caption “THE EV IS PREVENTING CHARGING,” before displaying “EV IS FULL.”



It was obvious that the charging system within the MG4 was defective.



The car was delivered to the local MG Dealership – Frasers Cars, Falkirk on 9 December 2024 for repair and it still remains there with the fault not remedied.



In these days of Hi-tech plug-in analysis, I find it difficult to understand why my car charging fault cannot be found and repaired.



I would be interested to hear of any other members with similar experiences.
I have an MG5, same problem, stops charging at 70% with EV full message
 
Hello,
Your charging problem appears to be a similar issue to that which I had experienced.
The problem would appear to be that the CCU over several months of usage, becomes confused and this component requires to be replaced with an upgraded module.
Sadly, MG Dealerships appear to want to solve problems like this using their own in-house knowledge and don't think outside the box.
In my own case, I sought the combined knowledge of MGEVS and they confirmed that the CCU issue was a well known problem.
While my MG4 was languishing in the MG Dealership for many weeks, I returned to them and provided them with the remedy. They don't like being told the correct answer!
The CCU was replaced and the car returned to me in a few days.
The car has been charging correctly without further issues since early January 2025.
Good luck!
