MG ZS missing V2L function

[Neilat226]

I have just received a reply from Miles ref the the question regarding V2L problems on some 2023 registered cars.
Unfortunately he not able to provide an instant answer, due to holiday commitments.
But has promised to answer the question as soon as he possibly can.
He will be attending a dealer conference on the 10 July and he will raise the question there, if he does not hear sooner.
Personal, he has NOT heard anything regarding the removal of the V2L function on the ZS EV ( face lift ) himself.
I will post ASAP folks !.

Thanks very much!

Okay, no prob's, thanks for confirming. I assume the car will remain unlocked?, will the 12v battery continually top up if in ready mode?

Yes to both but you can keep car lock if you stay in it ?

You are welcome @Neilat226 ?.

I think it'll be okay while we're nearby, but if go off sightseeing will just unplug the cool box and lock the car, hopefully it should still keep stuff cool inside until we get back and can plug it back in again. Not ideal, but better than nowt ?

I appreciate this is from 6 months ago but still...

This is what I see on the top of the inverter in my ZS. If any folks with a working V2L can post what is on theirs that would be useful.

[Susanna]

This is mine. Works perfectly

 

[Neilat226]

Thanks Susanna ? How old is your ZS?

Here is my inverter info. The number top right is the same as ChunkyMonkeys. Susanna’s is a different number.

@Neilat226 I took delivery at the end of November - build date was June/July I think.

Trophy LR collected mid March 2022.
Our V2L operated fine in discharge mode but required the car to be fully booted and unlocked.
After the first service in March 2023 it received a software date that now allows the car to discharge to continue, when the car is closed down and locked with the fob.
This is what the top of my inverter states.

 

[Neilat226]

Most of the info is identical, except the numbers top right and beneath VMAX, if only we knew what they meant?, I'm guessing version/batch numbers and serial numbers within that? It's also curious that the word NO to the right of CHN is printed on on some and handwritten on others.

Could do with a few more folk to send in theres so we can see if there's a pattern?

The number below VMAX looks like a date in the form of YYMMDD, possibly the manufacturing date of that particular CCU unit. And that seems to track with it being generally a few months before the car was built/delivered.

What I also find interesting is that none of them mention AC output. Maybe the inverter is not actually part of the CCU?

They say AC\DC output 230-250v 22A max

Makes sense about the date ?

Read it again. It says "AC/DC OUTPUT 230-450V 22A MAX". That is DC output.

My numbers are 11473414 and 221128. Again, a manufacturing date of 28th of November 22 makes sense for my car, which was built in February 2023.

And I'm beginning to see a pattern. All the cars where V2L doesn't work have the (batch/revision?) number 11473414.

No it for AC just like the input 32a =7kw on the line above for changing so output is for discharge 22A max is about 4.5kw which makes sense for the 2.2kw constant draw that's recommended for v2l

AC\DC input (AC charging)

AC\DC output (V2L)

DC\DC (heating)

DC\DC input. (When DC charging for running car and heater not for actually charging the battery this is done direct with the DC charger)

DC\DC output (for charging the 12v battery and running electrical equivalent in the car)

That's how I see it

 

[aserraric]

Sorry, but no. The "⎓" symbol stands for DC ( "∼" is for AC). This is the output to the battery. You wouldn't need 450V for an AC output anyway.

The first line is the input from the wallbox or ICCB (while charging).
The second is the output to the HV traction battery (while charging).
No clue about line three.
The fourth is the input from the HV traction battery (while driving).
And the fifth is the output to the 12V battery / rest of the car (while driving).

 

[Neilat226]

I have no clue what’s what I’m afraid, but as all the info is the same on all the labels and given that some cars can do v2l without problem, the ones that can’t should also be able to so maybe it is a software issue after all? Or do you reckon that v2l is done elsewhere inside one of the other lecky bits of the car?

 

[Gadget Geek]

If you use Google Translate, the unit is the "high and low voltage charging module". The first AC/DC value is "input", the second AC/DC says "output" and the same for DC/DC values. There is no mention of V2L, voltage export etc, so this is probably just the type 2 charger.
