Blimey! No thanks. (Was curious as to how much they retailed for.)

Yup, see my post 3 or 4 back which shows the breakdown of the type 2 wiring. They are a complete rip-off currently.

Yeah, shocking (hopefully not literally) really. Total Rip-off.

I'm not an electronics engineer, but looking at it the switch is probably a 'nice to have' rather than a necessity, so a type 2 connector, some solder and a thermal fuse and one could probably make it by chopping the plug off a standard extension lead and attaching that. It really is that simple.

I expect OEM offerings at reasonable prices.

look for that. Here i posted my wiring for the V2L Adapter working on ZS EV and Marvel. Have fun with it and save some money.

Build Vehicle to Load Adapter yourself, DIY V2L

Hello to everyone who would like to build the V2L adapter cheaply themselves.
I recreated the V2L adapter for the MG ZS EV FL. 300 Öcken are too much for me. A type 2 plug (female) is required, a 1ph is sufficient here, 3ph are not output. I bought a 3ph plug on Ali, which was there in about 2 weeks for just under 40 euros. The following interconnection must be made in the connector:
L, N and PE of course to a line with Schuko socket, Cee, or whatever. I took a 3G2.5 rubber cable with a Schuko coupling. The CP pin must be connected to PE. The PP pin must also be connected to PE via a resistor. The resistance must be greater than 440 ohms. Smaller resistance values are not possible, with 440 ohms it works perfectly. The value gives a voltage drop of 1.58V across the resistor. I tried to relate this voltage value to the IEC 61851. Since I don't know the exact wiring inside the MG on the CP pin, I can't give any more precise information. Obviously the CP has to be grounded, but the PP has to reach a certain voltage level. The interconnection takes place in the connector. This gives you a clean adapter with a cable length of your choice. The whole thing with cable and Schuko socket costs less than 50 euros.
Of course, I do not take any responsibility for damage to the car in the case of a replica! The adapter works perfectly.

Hi there,
thanks for the information. How did you come up with that?
Do you have a picture of the connector?

I have long searched the net for anyone who has such an adapter and sometimes unscrews it. In the forum for the Ioniq 5 forum I found the following threat:
viewtopic.php?f=531&t=64282&start=190
In addition, I have included the following essay:
https://www.researchgate.net/publicatio... _Standards
Here the basic function is explained, e.g. for AC charging and the communication that takes place. The IEC 61851 doesn't leave much leeway for a manufacturer's special quirks, as he clicks on the car that a factory discharge adapter is plugged in. So it was not surprising that the Ioniq adapter is quite simple. The same wiring didn't work with the MG, but from the basic idea of the Ioniq there were only a few variants until I found the working circuit here. The connector came with 2 pieces of 220 ohm resistors. One didn't work, both in a row did. Then left it at that. According to IEC, either 5V is drawn over 330 ohms to PP, or over 330 ohms to PP and then over 4.7 k ohms to PE/ground in the vehicle. The two values would result in a different voltage drop at the connector between PP and PE at 440 ohms outside the vehicle. Since there are 5V at idle, there shouldn't be a 4.7k ohm resistor between 330 ohms and PE. I then gave up reverse engineering. The thing works, that's all I wanted.
I only have a horrible picture when I connected some kind of lamp to experiment to see if it really works. The two signal contacts and the PE are still hanging out of the type 2 plug, so that I could switch different switching variants outside. Even the Schuko adapter is still some kind of basement find. Finally, I made the connection in the connector.
Here is the link to Ali....

Hi there,
you should also be able to use / convert these adapters here, provided that the type 2 plug is screwed on.

Hello Klaus,
Unfortunately, you cannot use the cable because the type 2 plug is "male", i.e. with pins. This is intended for plugging into a charging station, so that you can charge an e-bike battery or similar at a public charging station. A certain simulation circuit has to be installed there too, so that the charging station thinks there is an e-car attached....
On the vehicle side you always need a "female" plug, so actually you should say coupling. The "female" connector has sockets, not pins.
Attached is a cheap plug from a source in Germany. This is only one-pole, but as I said, that's enough, since the bidirectional charger in the car only outputs current on one phase....

Thank you for your report, your fingers are itching
In the Ioniq 5 thread, the Forent LTH put a switch between CP and PP, did you do the same with your version?
And according to the circuit diagram, the CP - PE connection also runs via the resistor, it sounded different with you. Or does it not matter?

A switch is not necessary with the MG (thank God). You can also connect the CP to PE via a resistor. Here, too, I had the 220 ohm resistor in there when trying it out. Also worked. But I see no need for resistance.
The Ioniq seems to need the signal via the switch with a time delay to release it, so plug in first, then press the switch. Thanks to China, the MG doesn't care. Static interconnection, plugging in and you can already see in the discharge menu: Start discharging..... After activation, it feels like it takes a few seconds.... and the light goes on

Awesome - thanks DIY V2L. When I get my Alibaba V2L cable I'll be sure to post how it's connected inside. I'm building an EVSE which tracks my solar output, but would like to add autoV2L so it can reconfigure as a V2L adapter to discharge the car into cryptocurrency miners at night.

I made a V2L cable and it works. Thanks to DIY V2L for the details.
I took a Type 2 connector and cable from an EVSE.
I cut out the 680 ohm resistor (between PP and PE) and replaced it with 440 ohm (2x 220 ohm in series).
At the other end of the cable I connected CP to PE with a wire link.
My MG ZS recognised the cable and let me switch on discharging.
The 40W light bulb illuminated.
EDIT: I've just discovered that CP doesn't have to be connected to PE. It works with CP left disconnected!

Please can you provide details of where this can be ordered. My dealer says it’s not available yet for order.

Hello,
You can order this adapter (23€) from Ali : 6.94￡ 44% OFF|EV Charging Station Conversion Plug Power Supply Socket AC Charging Station Adapter for Scooter Electric Vehicles RV Caravan|Battery Cables & Connectors| - AliExpress
(the first one, simpler, female plug without light)
Inside, there's a 1000 ohms resistor between PP & PE (and direct wire between CP & PE : switch to add ?)
Juste have to replace with a 680 one.
Received mine, will do the change soon to test on my MG ZS EV.

It's 6.94 for "new customer". In reality : 23€ (20GBP ? ).
TESTED => IT WORKS !!
Sorry, no pictures (another one job to do it )
To open case :
1/ remove 4 screws from top (plug).
2/ inside, there is 3 more screws to access to car connector.
So, at this level, there's a direct white wire from PP to PE, and a 1000ohm resistor from CP to PE.
Remove both of them ! (yes, don't be afraid : i was mistaken, as resistor in not on good pin).
Then take a 440ohm resistor (in my case, 2 x 220ohm resistor in serial), and solder them between PP and PE (replacing white wire).
Left CP in the air.
Double check connection, and take care to high voltage pins.
(Note : if you mistake CP & PP, it just doesn't work; no way to destroy your MG )
Then remount case in reverse order.
Plug adapter in vehicule socket, dual start véhicule to start HV battery.
info tablet is directly on discharge screen.
Press start discharge, and you can connect anything below 2000W.
When discharging, adapter is locked in vehicule socket, so no danger.
Adapter now stay in car trunk, with charging cables & so on.
Disclaimer : this is a DIY modification, take your own risk, take your responsabilities.
Be always careful because you're always playing with high voltage.
Edit : thanks for all of whom find a way to activate discharge mode by this tiny resistor !
i ordered this adapter last month, tested it last week with no luck, but i was sure it was a good base to make a fully functional adapter. It is done.
