ZS-EV Software

[Deepbluexl]

Hi,
a friend of mine has an ZS-EV EU (MY22/23?) and has issues with the App connectivity.
So after a few days the Car will not react to the commands send from the App.
It only cures itself when driving for a longer periode of time.

For my MG4 there where updates (Infotainment + TBOX) available and i never experienced connection issues again.

The Dealer tried something like unbind/bind, will help only for a few days but is not a permanent fix.
He said no updates are available and i'm quite sure that this is not true.
Car is running R25 and Tbox 11 Version.. don't have the whole SW name available right now.

Can someone here post their SW Version of the car and if you have issues with the App connection?
Not quite sure if the UK Version has the same number sceme.

In additon is there also a LKA update available (SC077) like the MG4 received?
Thanks..

I think that after a period of time the car "goes to sleep" and wont respond to the app. I find that unlocking and locking the car "wakes it up" and the iSmart app then connects.

I understand, but I thought maybe this should be possible to be fixed as other models are working as expected.
I assume the platform is abandoned, dead and no further fixes will be provided..
But please if you have some infosl about your installed SW Version do post these for comparison.

They do this "Go to deep sleep" because in the beginning (And of your car does not have recent software) it will only charge the 12V battery when the car is on and in READY state.

Since the whole car infotainment and all other modules run off of the 12V battery it is shutting down to prevent the 12V battery draining.

On later firmware version it seems the car will wake up and charge the 12V battery i it gets below a certain level.....But the deep sleep has not been removed.

I dont think you should expect any updates to the software except if they find some serious problem or something that requires a recall to fix.

Hi Deepblue,
My car has had a complete software suite update after I had MG app connectivity issues. The connectivity issues arose after some warranty work was carried out. Someone accidentally disconnected the 12v battery whilst the car was in it's 'Ready' state. That's like shutting down your Windows computer by pulling out the plug from the wall socket. It caused some software corruption. Myself, dealer & MG customer support tried all sorts to correct the problem but to no avail.

In the end the only solution was to upgrade the telematics software that runs the cars main computer from R25 to R27. Once this had been carried out the car was able to see upgrades for all 6 other computer modules in the car. The technician duly downloaded & installed these additional upgrades. After that all connectivity issues were cured. Everything works great now.

If your dealer tells you there are no other updates for your car when it's running R25 inform him he can upgrade you to R27 & loads of other updates will immediately become available. These should cure your issues. My car also wakes up & charges it's 12v battery when it's needed.

Ours is on R25 and wakes up, so i don't think the version of software in the infotainment system is what makes the car wake up and top up the battery.

I confirmed this while we were on holiday, the ZS EV was stationary in the driveway and after about 6 days i could see the battery voltage was suddenly up.

Still, a day or 2 after it went into deep sleep and we were unable to communicate with it before we got home and had it put in READY mode.

PS. My ZS EV is integrated into Home Assistant and it reads they battery voltage along with other parameters of the car at regular intervals.

After it went into deep sleep mode Home Assistant was also unable to speak to the car.

I think it is great, them updating the software to support the car charging the 12V battery when it gets low, but somehow they seemed to forget to remove the "Go to deep sleep" function, at the same time.

Yes my car already charged it's 12v battery prior to the software updates. That has been the case for all MG's for the last two to three years I believe.

Going to deep sleep is to allow the car to minimise power output from all sources. After a set period of inactivity the car believes you are not going to use it for a while & goes into hibernation to conserve energy. That's all apparently. Most EV's do this but might have slightly different parameters to do so.

Have you tried charging your ZS at a Tesla charger yet hmadsen?

 

[Deepbluexl]

Thanks for the response.. the car belongs to one of my friends, so I'm not familiar how it will behave as I don't have daily access. Ok so it seems that R27 to be available, the other Software which is relevant for connecting the app should be the TBOX.
This Version is something like SNAKP11.. the TBOX had an impact on the App connecting in the MG4 as well and this was updated from 18 to 23..
Can you identify which version is on your ZS? Should be shown in Software Info..

No i really should try it sometime, but the thing is, my wife uses the car every day for work and it is always charged at home, so i rarely get a chance.

I do have a Tesla supercharger about 4 miles from where i live so i could potentially go their in a weekend and since my own EV is actually a swasticar, it would not be that big of a deal setting up the MG in that app as well.

That would be interesting to do!

I'll take a look tomorrow (Monday).

Have you tried charging your ZS at a Tesla charger yet hmadsen?

Now i have...

Just drove the 4 miles to the Tesla charger just to test it, felt it was important because if it would not, MG would have had to do it for free as the seller droned on about how they had, had the car on the computer all day, updating all the different modules before delivery.

Left car in "Ready" mode, opened the chargeport, connected the CCS connector, went into the Tesla app, selected "Charge other car", selected location and selected the charger i was connected to.

It said "Connecting", the Tesla app said it could take as long as 2 minutes for negotiation to be finished and charging started.

BUT, after less than 30 seconds it changed to Charging, the car screen indicated it was charging and the Tesla app was indicating it was charging.

Only added 2% of charge as the price is higher than at my home charger, but these are the numbers.

SoT when i started 33%

Ambient outdoor temperature 16C (Has been up to 24, but not for long today)

Charging speed : 64KW

I consider a speed of 64KW at 33% SoT, with a battery no more than 20C warm to be pretty decent, considering the charge curves i have found suggests that it could be at 75KW, but i bet that's with a 40 degree battery and as said, this was at 20C max, i did no battery precondition and car has been stationary for most of the day.

So indeed, it seems my car HAS got the update that enables it to charge at Tesla chargers, even though i had to be one of those people i, as a Tesla owner really hate, and park in an awkward position for the V3 chargers cable to reach the charging port.

Tesla app showed the SoT (With a small delay compared to the ZS EV's screen), amount of electricity i had gotten and total price.

This is good news! Well done & thanks for trying it out. It's always nice to know you have that option should you need it. Thanks again for reporting this to us all.

Yes, we are unlikely to ever need it, we have the swasticar for longer trips, we are a family of 5 and the kids are 12 and up so the extra space compared to the ZS EV is nice, but yes, nice to know, if the need is there.

I can do a readout with the eZS app if someone is interested in the software versions, but i dont know what module has to be updated and if memory serves the names in the app is not very telling.

But if someone wants it, i can do it, to compare with their own readouts.
