V2L switching off after a few seconds ZS EV 2022!

[fatgit]

I have the FL SR Trophy and can only use V2L in ready mode and unlocked, anything else and it just turns off after a couple of minutes.
My lead is a DIY one with 470ohm resistor

My ZS EV Trophy (delivered December 2021) can do V2L in ready mode or stop mode. In ready mode, the 12V battery is charged, but the DRLs are on and the car cannot be locked. In stop mode, the DRLs are off and the car can be locked, but the 12V battery isn't charged and will go flat after a few hours.
I recently had my 1 year service (by WLMG Ruislip) and no software updates were needed (or so they told me). I was concerned I'd lose the ability to have V2L in stop mode, but it seems not.
I have an official MG V2L cable (on loan) which has a 2k resistor in it. It seems either 2k or 470 ohms works to tell the car it's a discharge cable.

@Julian256 can you confirm when you unlock car it pauses charging so you can remove cable as this was one of the big updates?

Just about to swap my 2020 MGZSEV Exclusive for an LR Trophy Connect.
Is there any facility for V2G connection?
My day time rate is 57.44p per kWh and night is 13.43. This averages out at about 30p per kWh. If I can charge at 13.43 and feed the property back when not using the car it would be advantageous. Can this be done?

This is a perfect question for @Ayoull to answer !.
V2G is a more complicated ask over V2L I understand !.

Hi
Has anyone had problems with their V2L discharging switching off on a ZS EV 2022?
I have a type 2 plug with a 470 ohm resistor fitted between PE & PP, it was used to power individual items such as washing machine or tumble dryer (not at the same time!), the resistor still shows 470 ohms (I have replaced the resistor but still no good!).
The car recognises the discharge cable, when I press the discharge button, car shows discharging (relays switch) started but within 5 seconds car says a charge cable is connected and the discharge cable is not connected! There does not appear to be any loose connections (I am an electronic engineer so not a total novice!).

Thanks in advance

I would look for better tariff

The best you can do is have an extension lead to plug in some high wattage devices, kettle, toaster, air fryer etc, but obviously not use them at the same time.

V2G isn't implemented in any MGs currently those with V2L technically have the prerequisite components for it but don't currently enable it, also you need a V2G enabled EV Charge point on your house.

What people have done is Jerry rigged V2L to their homes, without consideration of wider impacts of the implemention.

There are some people who have taken a 12V inverter with G98 loss of mains protection and put those into their car, but your issue is you're limited to the out put of the HV to LV battery charger which is believed to be around 2kW which is enough for background loads and lighting but not your high load items like ovens kettles and such

Mine happily powers a 3kW kettle.

I'm saying 2kW if you're running a 12v G98 inverter from the 12v battery as it was measure that the HV to LV (12v) system can only sustain 2kW charging for extended periods of time.

I'm not talking about the V2L capabilities of the onboard charger

The best you can do is have an extension lead to plug in some high wattage devices, kettle, toaster, air fryer etc, but obviously not use them at the same time.

For this, you're actually better putting high energy loads (as opposed to high power loads) on the V2L. Energy is what you pay for. Also, higher power loads are more likely to run into the car's power limit. So things that run 24/7, like a second fridge and/or freezer. I'd probably not run the primary fridge on an extension cord that is switched over a lot, just because it's the biggest nuisance and cost if you slip up and it loses power for several hours.

3 kW jug x 2 min x 5 times per day = 0.5 kWh; 100 W fridge x 12 hours = 1.2 kWh.

Ideally, you'd want some sort of gizmo that puts these loads on the grid at night, and on the car's V2L during the day if the V2L is plugged in and working. I can't immediately think of such a gizmo, but I'm sure there are some if you look around.

No, my car doesn't do that. No software updates were applied to my car as part of my 1-year service, so it behaves the same way it did in December 2021 when I took delivery. I'm now thinking - if I don't ask for software updates, I probably won't get software updates (unless it's part of a recall).

I found this to be the very same case on the Gen 1 model ZS EV TBH.
Soft ware updates only tended to be applied under two conditions.
1 ) If the car was in for any customer related problems / complaints, then checking and updating the software, was the first port of call.

2 ) If a direct request from the customer was made to check for any of the latest updates, otherwise the annual service would get performed and the car get's returned unchecked for the updates.

Connecting the car to the diag computer and checking for updates takes time ( assuming they can connect to the MG server on the day ) then if any updates are found, these updates needs applying to the car.
Hopefully the updates go through okay, or it can be become a big problem to sort out, which can take up a lot of workshop time !.

Do you not do DC charging as this was the side effect of the fix for it and all software updates should be applied as service

Yep it's just laziness as it takes time

Yeah, I do a mix of 50kW DC charging (Osprey mainly), 7kW charging (mostly at Wycombe Retail Park cos it's 14p/kWh) and granny charging at home. Had very few problems with DC charging, I've only had to pull the release cord a couple of times.

 

[Mg4me]

Thanks for the info N2STY, I didn't have a 2k ohm resistor handy so I tried 4 x 470 ohm resistors in series (total 1880 ohms), it didn't work - same symptoms. For info there is nothing connected to CP not even a floating wire.
Aussi55, Here is the link to the cable I got from Ebay, it worked for 6 weeks!
MG EV V2L cable
Could there have been a software update sent to the car or can that only be done in a MG garage?

Sorry to hear that. I bought mine from:

MG V2L Adapter Vehicle-to-load Bidirectional TWO-WAY Charger Electric Cars Extention Socket MG ZS EV MG 5 MG4 MG Marvel R Mulan - AliExpress 34

Smarter Shopping, Better Living! Aliexpress.com

and it worked OK so far. I ran a 1200w microwave + air-fryer + fridge simultaneously for about a half hour and all worked without issue. Though I won't overdo it. I've achieved my goal to have fridge backup if the power goes out.
The only nagging issue is that the driving lights remain ON the whole time I'm doing V2L. very annoying.

Therefore the car is in the "READY" mode with the doors unlocked then I guess ?.
Without this, you risk of depleting the 12 volt battery.
