MFG chargers - HV battery shut off/bricking

That's good to hear, can you now stop AC charging by unlocking the car?
As promised, I have just tried to see if I can now remove the type 2 cable, by unlocking the car with the fob, while it is on charge from our wall box and YES đź‘Ť it is now possible after the software update to the BCM ( body control module ).

I've always suspected that is the side effect of the update
Did you get the entertainment update? If so what version have you got and has it sorted the dab art work?

I was told that the car was only available to accept TWO software updates.
One was the BCM module update and secondly, there was a update for the info unit.
I have not checked the version number ( its been a bit hectic here for the last couple of days ) but I have noticed there is still no art work for the radio stations present, do you have this @N2STY ?.
I was wondering if the info unit was to correct the slight crashing / bugs in the system it can have ?.
On odd time, I would boot up the car into READY mode and radio would fail to provide any sound.
Increasing the volume made no difference at all.
It could be quickly resolved by holding down on the HOME button for about ten seconds of course, which rebooted the whole head unit and hey presto, we have music again !.

I have found the very same thing @hmadsen.
I had a “off the record / on the car park” conversation with a workshop manger who was very open and honest about carrying out software updates on customers EV’s.
Not wanting to go into too much detail of the conversation, but it was a given that software updates where only carried out ( with the help from MG Tech ) if the customers car had reported a major problem / been recovered or if the customer had directly requested for all software updates to be checked and then applied at the time of the annual service intervals.
“When things go according to plan it’s great, but when they don’t, it can be a huge headache, it causes absolute bedlam to workshop loading times”.
I then asked him was it fair to say that SOME main MG dealers had never even seen an electric car, let alone worked on one until the ZS EV arrived ?.
“Some of the tech’s have received EV training but that is it, we are learning as we go along, and very reliant on the back up of MG Tech”.
So, this explains why some dealers are not willing to invite trouble if they don’t need to.
In fairness, dealers have now seen two versions of the ZS EV and the MG5 plus the recent MG4 over the last three years, so you would have expected confidence in updating these cars to have improved by now.
Personally I feel that when choosing a dealer to apply vital updates, I will choose a dealer who has EV Master Tech’s that have gained EV experience, before working on the MG EV range if I can.
Some dealers who have multi franchises and have gained their EV experience when working on cars like the Nissan Leaf for example, which has been around a lot longer than the MG EV models.
These dealers can have a ten year EV knowledge start on some of the single franchise dealers.
On Tuesday I will be submitting our ZS EV LR for its first service and checking for at least one software update I know it has not received.
We will be making a round trip of almost 200 miles to have this work done correctly I hope, by the guys at Chorley / Barnsley.
I have three MG dealers all within a 20 mile radius of our home address and will probably pass another 5 dealers on route to Chorley.
The reasons I gave above is the reason why I am prepared to travel this distance to have the work done.
My only concern is if the link the the MG server is down, making updates unavailable then we will have travelled almost 200 miles for a 30 minute first service !.
Keep your fingers firmly crossed 🤞 for Tuesday for me folks !.
Your comments regarding the lack of trained technicians is quite worrying particularly as it was a workshop manager you were talking to. I retired from the industry a few years ago now, but I was the senior technician and then workshop manager of a company that managed various press fleets. Included amongst them was Volvo, Ford, Renault and Audi, each with either full electric or a hybrid vehicles as part of their fleets. While I was still working hands on, nobody was permitted to work on any electric vehicle without a basic EV qualifications and there had to be a senior technician (Me) that was responsible for evaluating and work and making the decision as to who could carry out any repair and whether the car needed the high voltage system isolated, which again, only a tech with the correct qualifications was allowed to carry out. There were strict rules regarding a proper area for EV’s in the workshop, and whilst working on any high voltages the car had to be fenced off and nobody was allowed into the work area. So to hear that a main MG dealership is winging it and there are dealers possibly operating without the proper trained personnel is quite worrying. I suspect the HSE would have a hissy fit If they knew! As I say, this was probably three years ago so maybe the rules have been relaxed since then, but I doubt it🤦‍♂️
 
Dear All,

MFG chargers - HV battery shut off/bricking

Yesterday I tried to charge at the mfg chargers located at Redbridge postcode IG4 5AQ. Charging my 2022 ZSEV Trophy Long Range.

Initially the chargers wouldn't properly 'handshake' with the car - I got a 'connecting' screen for a long time, then a 'charging failed' screen. This happened on 4 of the units. After the last attempt I tried to move off and the car had disconnected the HV battery effectively bricking it. To fix this I needed to disconnect the 12 volt battery to reset the system.

After one more attempt the chargers finally worked - coincidentally I wiggled the ccs plug in the car socket then finally it started working. I regularly have used many other brands of rapid chargers without similar issues.

Has anyone else experienced this issue with MFG/other chargers? Tried to search the forum before posting - apologies if this has already been covered to death.
I wonder if the charge setting in the car or the App was preventing the car from charging, then when the 12v battery was disconnected the charge setting defaulted to allow a "full charge". I only say this as my LR wouldn't charge on about 5 chargers I tried until I discovered the charge setting wasnt allowing a "top up". Live and learn!

I doubt very much that any dealer would be stupid enough to allow a none trained EV Tech anywhere near a EV with out the necessary accreditation to be totally honest.
The risks to the company are just FAR to great regarding the very good chances of being taken to court in a man slaughter case, in the event of a serious / fatal accident.
The think the problem here in SOME cases, is not the lack of EV training, but the lack of EV experience TBH.
One dealer I paid a visit had a dedicated two bay shop for working on EV's only !.
The doors where open and I could not help but notice there was a very large space, red high lighted on the back wall, with a huge what looked like a shepherd's crook hanging on the wall.
It was big enough to pass around somebodies body.
No prizes for guessing what it was made out of and it's purpose for being there was folks ⚡!.

Very interesting

I only say this as my LR wouldn't charge on about 5 chargers I tried until I discovered the charge setting wasnt allowing a "top up". Live and learn!
Perhaps the problem isn't only of MGs, my daughter with her Jeep Compass plug-in then fail charge at a charger Enel near Bologna Italy had to go the jeep service for reset charger.

Yes, the crook is for exactly what you think and the company I worked for had the all first aiders sent on special training and a defibrillator was installed.
