Vehicle to Load (V2L) on MG ZS EV

[@JulianIlett]

You can now buy a V2L cable for the MG in a range of lengths and colours from evcables.co.uk evcables.co.uk/products/mg-vehicle-to-load-v2l-discharge-cable

[@YourMotherSucksCocksInHell]

£108.42 for a 0.5 metre cable? Is it made from 99.9999% oxygen-free copper?

[@JohnDoe-bd5sz]

One thing to note. The resistor you use seems to be either 1/8 or 1/4 watt resistors, but the resistor value schematic you printed from the internet, says the resistors on either side is either 1 or 1/2 watt. I don't know if this actually matters, but if i were you i would get a 470 Ohm 1W resistor fitted, just to be on the safe side. Also i would be interested to know what kind of protection against electric shock this V2L offers. In my country, there is a fuse to safeguard against over-current, and a fault relay, that will trigger if the live gets connected to earth (through a person for example) i think that's called an RCD. I wonder what the car would do if it was in discharge mode, and someone grabbed the live wire while in bare feet, standing in a puddle. The RCD and fuse is mandatory for houses here, but i wonder if there is something similar built into the discharge circuit.

Very interesting, thanks for sharing. Our first gen ZS EV doesn't have 'official' V2L so we had to go old school and wiring in an external DC to AC inverter to get 230 volt AC. Great video!

[@therealaristo]

I have the first gen too, did you suceed by creating a V2L solution?

That's really cool! Such a great feature to have. Thanks for these lessons on charging cables.

[@craigbourner5838]

I'm just curios. I chant test it for my self because I drive an ID.3.

[@billwarren8076]

I would imagine that there are resistor values that specify US (110v, 60 Hz) as well as 240v 50Hz in there somewhere

[@howthphotoclub3182]

Thanks!

[@mikeselectricstuff]

As the plugs are expensive, an idea for a cheap combined Granny charger ( or type 2 cable) V2L setup : Take the standard granny charger ( or Type 2 cable) , chop the cable and put the ends into an outdoor 13A socket. Add a double pole switch to select modes: Pole 1 connects the car PP to either the Granny/T2 PP or the 470R to PE Pole 2 connects the car CP to either the Granny/T2 CP or open Opening the CP ensures nothing bad should happen if the granny's 13A plug is accidentally plugged into a 13A socket while in V2L mode, as it shouldn't close its relays. As long as the car disables the V2L immediately if the resistor disappears, nothing bad should happen if the switch was flicked while the 13A plug was live....

[@JulianIlett]

On my EVSE, PP doesn't connect to the granny box at all (just has a 680R to PE inside the Type2 connector), so pole1 of your switch could simply select between two resistors, 680R and 470R. I can see the benefit of a combined EVSE/V2L for the Ioniq5 where the V2L can be enabled remotely, but the MG ZS requires several actions inside the car to enable V2L (turn on car electronics, start discharging on infotainment display) so a combined unit makes less sense.

[@Morris1581]

Thx for youre Test. I hope you will Test soon, how much watt we get out of the Car 😃👍🏻

[@christopherperry8693]

So, with a with the addition of a correct switch, you could switch between two diferent resistors and have one cable that both charges and discharges ?

[@KDBAO]

Cheers for making this video mate. Our car charger was recently replaced and I kept the parts from the old one. Which included a 3 or 4m cable with the car end connector attached and bare cable at the other end, so I thought about making my own V2L cable and saving a few hundred quid. I have an MG4, so I'll start off at 470 ohm for the resistor and test it. I have high hopes it will work flawlessly.

[@JulianIlett]

Should be fine. I've heard that 2k ohms also works but may limit the power output to 2.5kW (or thereabouts). One guy said that he was able to pull 7kW from his MG4 using 470 ohms.

[@bellshooter]

A question Julian, do the different resistor values set the output voltage/frequency/current?

[@AdamWelchUK]

Interesting. Is it pure sine wave?

[@JulianIlett]

Yes it is. I'll show that on my graphical multimeter in the next video.

[@juanjo6190]

On my 2022 MG ZS EV the V2l only works with the car on. If you turn it off, after a minute, at the same time that the screen behind the wheel turns off, the V2L stops working. Sometimes after a few minutes the screen turns on again and the V2L works for another minute and it stops again. I have tried it with the original V2L cable of the brand (very expensive) and the same thing happens. I advise future buyers that the V2L is important to keep these limitations in mind. Your videos are perfect, direct and friendly.

[@abambac]

Great video! I’m getting everything for my cabel. I have ordered 1W 5% 470ohm (470R)

[@lookoutleo]

Very nice. I wonder if this works on the older 44kwh mg5

[@matthewmiller6068]

Very interesting - this would also open up the possibility to have a "jumper cable" to fast charge a dead EV from a working one to limp it to a charging station. If it was really done well maybe even have the building charging infrastructure use the same port and protocol vs a fixed cable and be able to use the same cable or even reverse the cable to supply backup power to a building. Lots of cool possibilities.

[@ukslim]

Presumably a 2-pin charge cable plugged into a V2L adapter would achieve the "jumper cable" you're describing.

[@jlucasound]

Having this cable could save lives in an emergency situation where power is needed in a remote area. Electric/hydraulic "Jaws of Life"? Stranded in a blizzard? Well, I guess the car already has heat. How efficient though? A little electric heater you design that will keep you alive long enough for help to arrive but not deplete your bats to zero. (I have no idea how efficient the heater is in an EV). Maybe for a second vehicle with occupants, that is disabled. Anyway! I Love It! You are awesome Julian!

[@mikeselectricstuff]

I was wondering how the Ioniq 5 V2L adapter did it, I even considered trying to get an over-the-weekend test drive to investigate ;-) The Ioniq may be slightly different as it has a button on their V2L plug, to enable it without using the car's UI, so maybe something slightly more sophisticated. Was expecting to see some sort of authentication/signalling in there somewhere. I suppose the fact that on the MG you have to enable it manually means there isn't a risk of unintended activation, e.g. with a damaged cable, which could get nasty, I'd be interested in the inverter achitecture, if they've repurposed any of the OBC and/or inverter hardware to do it, or just slapped an inverter and some relays in. Do you hear any different relay/contactor clicks in this mode versus charging or running?

[@JulianIlett]

The Ioniq5 adapter is possibly even simpler. Delbouy did a photo teardown of the adapter here: www.ioniqforum.com/threads/v2l-inner-secrets-not-many.39857/ In his text, he says PP connects to earth (PE) and CP connects to earth through the switch and thermal fuse. But I can't see any connection to PE in his photos. So is it simply that CP connects to PP through the switch and thermal fuse? The thermal fuse (SEKI ST-22 95C) looks like a bit of an after-thought. I guess people aren't very good at wiring plugs and a few of these adapters got melted.

[@JulianIlett]

My gut feeling is that the OBC reconfigures itself as an inverter for V2L, possibly using the same semiconductors, because there are no additional relay clicks or contactor clunks. But that's just a guess. And I won't be lifting the lid on the OBC/inverter for at least 7 years :)

Are you going to use the same cable for charging and discharging, with a programmable device to switch resistors between charge mode and discharge mode?

[@burgersnchips]

Programmable device? A basic switch added to the handle could do this. You could put in the 680ohm and then have a 1.5k ready to place in parallel at the push of a clicky button. You'd need to be clever with the plug the other end though to make sure you can't kill yourself by touching the power being fed.

[@ecospider5]

Right knowing if it is 50hz or 60hz and how to control that is going to be really important if you don’t want to destroy the devices you plug in. 120v or 240v is also going to be important.

[@JohnDoe-bd5sz]

@@ecospider5 What devices other than electric A/C motors would care if it is 50 or 60 hertz ? Any resistive load like bulbs, water boilers and whatnot would not care, and anything with a SMPS would not care either as it just rectifies the incoming AC and then chops it up at a much higher frequency to make the DC needed inside of the unit. I suppose if you want to attach an old style alarmclock that runs the clock circuit off of the frequency it would matter as well. 120/240 is probably going to be the same as what you charge it with, so dependent of where the car is sold. Also, most SMPS driven devices would not care as they are usually rated from 100 to 300+ volts input.

[@ecospider5]

My primary use for backup power is refrigerator, air conditioner and furnace fan. If all you are doing is charging devices and running a lightbulb then a 12v to 120v power inverter is all you really need. But yes your toaster is not going to care about frequency.

[@UpLateGeek]

Very interesting stuff. Curiously, this would all be perfectly legal to DIY up to this point here in Australia. But you can't so much as wire a socket onto this without years of tertiary education, apprenticeship, certification and licensing. As we all know, everything is more dangerous in Australia, so you would immediately be electrocuted to death, then arrested if you tried.

[@JohnDoe-bd5sz]

@@arletottens6349 Yeah i heard that a specific episode of Peppa Pig (Childrens cartoon) was banned in Australia because it told kids that spiders are our frinds. In most of the world, there are no spiders that can actually kill you, just small spiders that can do you no harm, but in Australia, teaching kids that spiders are a small cuddly harmless friend, could get them killed :)

[@Berkeloid0]

It's interesting. I read through our legislation and it says that you do not need an electrical licence to be an auto electrician, so now that our cars can produce 240V AC, does that mean you're allowed to wire a socket as long as it's connected to the car and not to your house? What if you run your whole house off the car, or from scavenged car parts, so you're not connected to the grid? Can you do your own electrical work then, because at that point it's just a giant auto electrical project?

[@UpLateGeek]

@@Berkeloid0 My understanding [insert every disclaimer ever created here] is that if you wire a connector that can be connected to the grid, then you've committed an offence worse than murder (at least here in Australia). So wire a standard plug onto a cable and you'll have a tactical assault team knocking at your door within seconds. Similarly, wiring a standard socket into your house wiring (which itself is connected to the grid), and you'll have a similar outcome. But wire it into something that's not the grid and you'd need an illegal double plug cable to connect it to the grid, so that might be legal [see above disclaimers]. However to get the appliances in your house working off that, you'd need a completely separate set of sockets that don't connect to the grid, and then you'd be straying into the territory of regulations. It would need to be compliant with electrical safety standards, so if your house burns down and your extra wiring doesn't have the stamp of approval from a certified electrician, your insurance won't pay up (even if it is in compliance and not at fault).

[@Berkeloid0]

@@UpLateGeek Yes you're right there (although you don't need an illegal double-plug, you can just use an appliance inlet socket like they have on caravans to connect them to powered camp sites, and then use a normal extension cord.) In my case I'm looking at a remote property with no grid connection at all, and I don't want to have to pay a sparky to drive an hour each way to reach me every time I want to add a power point or replace a failed solar inverter, so it'll be interesting to see. There is an exception in the rules that allows you to do your own electrical work if you're off grid and an "unreasonable" distance from the nearest electrician, so maybe that could help too. I just wish we had a restricted electrical licence available where you could sit an exam and if you pass, you're allowed to do electrical work around your own home. That way anyone who has proven that they know how to do the work safely could do it legally without the multi-year apprenticeship requirement that makes it impractical.

[@JohnDoe-bd5sz]

Depends on what kind of computer you have. Most new computers have USB-C chargeports and these usually accept the PD (Power delivery) standard. If this is the case, you can get charger that do PD, and plugs into the 12V "Cigarette lighter" plug next to the USB and USB-c ports. If your laptop does not accept PD, then you need to look for a charger for your type of laptip, that has a 12V input instead of the 230V in the charger you have now. No need to get some fancy 12 volt DC to 230 volt AC, that you then plug your charger into and it then does 230 volt AC to 20 volt DC conversion. Much easier to get a 12 volt DC to 20 volt DC converter

Hello Julian. Thanks for all the information. I've read the entire thread but one question does not seem to have been answered. You say: The Hyundai Ioniq5 V2L adapter has a switch on it, which appears to start the inverter without having to enter the car. Looks like the MG always requires user interaction inside the car. But the German circuit has CP connected to PE and a question was asked: Would connecting CP to ground allow for the discharging to begin without needing to tell it to start? Have you ever tried connecting CP to PE or PP for that matter, to see if this is the case or if the "start charging" characteristics change in any way?

[@JulianIlett]

Pretty sure I tried connecting CP to ground and it didn't make any difference. Entering the car and switching on the car's electronics just so that you can start up V2L is a bit of a pain, but I don't know of any way round it. What's also a pain is that the 12V battery isn't charged during V2L (when the car is switched back off). Some cars don't have the ability to switch off the car's electronics after initiating V2L and must be left in the ready state with the DRLs on and the doors unlocked. It's also been reported that the resistor value has an impact on the maximum V2L power output: 2k ohms limits the output to 2.5kW and 470 ohms allows for more power. But that came from an MG4 owner. I've not yet tried this on the ZS.

@@jonathanr72 that would take 100 years. i have leaf 30 and even pluging in to a 13a socket which draws about 2.5kw only gives a few miles range in an hour. think aa will have to lug a 6kw diesel generator about or just transport us to nearest charge station

[@JohnDoe-bd5sz]

@@lookoutleo Or maybe a purpose built truck, with a battery pack, and a "fast charger" capability. Only need to charge the car to whatever is needed to reach the nearest "real" charger.

[@edwardvanhazendonk]

Great, kudos to the designers of this standard, possible ways to use a single connector in multiple ways. Thanks for sharing, I think not usable with my ID.3, but who knows maybe in the future.

[@JohnDoe-bd5sz]

I wonder if this could be used to blow up someone's car. Charge cable, modified with the resistor. Set the car to discharge and then plug it into the charger and start the charger as well. In reality, the charger probably needs to talk to the car about the charging before actually firing up the charge circuit and trying to deliver power :)

[@mahudson3547]

Another great opportunity for perpetual motion?

[@PlanetCypher_]

I’m assuming your going to want some form of fused connection from the T2 plug to protect your cable/load I’m sure the car would have this safety built in thought.

[@HarisIftakhar]

Hi Julian! I have an mg zs ev 2022 facelift (same as the one in video) in India and i have built a discharge connector using 470 ohm. All connections are ok and the instrument cluster also recognises the connector and displays discharger connected. But my head unit ui seems to be different and does not display any discharge menu and no option to start discharging. Hardware seems to be compatible and i suspect software issues. Your thoughts? Also could you help me with your head unit software version and details to compare with mine? Thanks

[@JulianIlett]

That's odd. Is the car advertised as having V2L in India?

[@HarisIftakhar]

@@JulianIlett No. But since it is a CKD unit, and has quite a lot of features not offered in india but offered outside india, i was hoping for it to have V2L, but i guess its having some hardware imssing which is why it doesnt have a discharging menu either.

[@whitehoose]

It's interesting stuff you say where to get a plug from, how it's done .... but could you please show how/where the resistor actually goes? you've shown the bulb wiring in great detail but the EV connector is only shown half uncovered and the really interesting bit is always obscured in the bird's nest. Is it pe - resistor - pp or is the resistor pp - R - cp it's not at all clear, even in slow mo

[@JulianIlett]

On the V2L cable, the 470 ohm resistor is placed between PP (proximity pilot) and PE (protective earth). I found that CP (control pilot) can be left disconnected.

[@whitehoose]

@@JulianIlett FYI it doesn't seem to work with Nissan leaf ... Bother,. Error says charge cable, so it's seeing something, just not a bulb

[@JulianIlett]

Does the Leaf have V2L?

[@whitehoose]

@@JulianIlett I was sure I'd seen a vid but I'dashed if I can find it. They were th ONLY car tagged by OVO for a V2H trial,. I was accepted but then it folded, something to do with shared feeds on the distribution. If you google there is a massive fridge sized thing from nissan that manages their version it and also shows v2l, so whether it's to spec or what I don't know. I expected that Nissan would have written the book, but maybe not.

[@deanervik]

Wonderful! You’re a legend.

[@ncot_tech]

So how long before your home made EVSE does both charge and discharge, using your solar when necessary?

[@JulianIlett]

I've certainly thought about it. Scary though - house mains one side of a pair of relays and vehicle-generated mains the other side. Not sure I trust my Arduino coding skills to risk that :)

[@eDoc2020]

@@JulianIlett I would definitely use a hardware interlock instead of software.

[@sirmiro2]

This information should go in the list of things to know for a "if s**t hits the fan" scenario. Could you show bypassing a solar system when the grid is dead too? (Another lifesaver.) But does this mean the same cable can't charge and discharge? (New to how EV electronics work, but look at having an EV as a reserve battery.)

[@sirmiro2]

@Wooly Chewbakker Yes and no. Safety for sure. But I want to use the car as an extra battery buffer for the house. Which seems a bit "hard" at the moment.

[@sirmiro2]

On Saturday I had a test drive of the MGZS EV facelift I was very impressed with it, Are you happy with yours?

[@JulianIlett]

Yes, very much so. It was a bit overwhelming at first because there are a lot of 'systems' to learn (lane keep, traffic follow etc.), but now I've learnt all that stuff it's very easy to drive. As charging infrastructure improves in the UK, I'll feel more confident to tackle longer journeys.

[@1larrydom1]

Hi Julian! Nice job here. I think one cable with a charge/discharge switch would be viable, lowering the cost even further if you didn't need anything other than a standard output end - or whatever you wanted to convert the output connector to. Also, a question. Would connecting CP to ground allow for the discharging to begin without needing to tell it to start?

[@JulianIlett]

The Hyundai Ioniq5 V2L adapter has a switch on it, which appears to start the inverter without having to enter the car. Looks like the MG always requires user interaction inside the car.

[@1larrydom1]

@@JulianIlett probably so you're forced to read the terrible English. That would annoy the hell out of me for what price I paid for the car!

[@JohnDoe-bd5sz]

@@1larrydom1 And look at a picture of the car, with the cable coming out of the side of the car, when in fact the charge port is in the front. Not a lot of care was taken when doing the menu's....Only good thing is that the car is OTA upgradeable on the infotainment, so it is possible they can fix that at a later date.

[@robertgoddard6787]

If that's giving you ac out , I wonder what the inverter output at 240 v. Is capable of powering . Wattage I mean , very interesting watching that . Nice 1 .

[@dh2032]

how big (size) is the inverter, extra weight which all needs moving, is it used for anything else, in the car or just this as in the video, go camping, or power for a caravan or something, could it be used say like a set of jump leads, to get car electric going from second cars with a full battery?

[@JohnDoe-bd5sz]

@@dh2032 The inverter that does the V2L is probably the same one that does the charging so probably not any extra weight. The onboard charger is a AC to DC converter, but if you build it right, it can also do it the other way round.

[@pmacgowan]

Can you do this on a Tesla M3 ?

[@JulianIlett]

Unfortunately not :(

[@wrightwells]

its been proved that AC output is not include in 2019 Model 3. kzbin.info/www/bejne/oonSnH17r72ql6s ....but its in the standard to putput DC , which has been done here kzbin.info/www/bejne/mWexY6OMhNqXldU so its need an inverter, which is actually how OVO Energy did the trial in the UK (but with CHAdeMO)

[@douro20]

I believe Aerovironment was the one who did most of the work of standardising the charging stations. Mennekes was, of course, a natural choice for developing the connector with their decades of experience in developing pin and sleeve connectors. Is that your daily driver now? I'm not sure I would want one as a daily driver unless I lived within the city.

[@JohnDoe-bd5sz]

With a range of 273 miles, it would have to be a quite big city for you to not wanting to venture outside of the city...

[@NiHaoMike64]

Now the question would be if it would be possible to connect a grid tie inverter and get it to charge the EV.

[@tomhanauer6919]

That's a really interesting point. I don't think for a second it would work, but it might well blow the car to pieces!

[@anythinf1]

[@MalcolmCrabbe]

I hope the MG dealership isn't watching this channel.... I wonder what the warranty T's and C's are with regards to the use of non authorised or DIY charging and discharging cables - You're a brave man Julian :-)

[@JulianIlett]

Well, the use of 3rd party charging cables is nothing unusual. I can't see why discharging cables should be any different. At some point someone will take apart an official MG discharge cable - if there's just a 470Ω resistor in there...

[@Dave2108]

So with that cable made, you basically have a Jump Start cable for other electric vehicle sort of. Thats if they have the 240v charger with them.

[@JohnDoe-bd5sz]

A very slow charger. Maybe 2 kilowatt per hour, so only able to add 10ish miles per hour. But offcourse...Better than nothing.

[@seymourpro6097]

Would be interesting to know whether there are settings to cover 50Hz and 60Hz and any current limiting. Here's hoping that the power is reasonably sinusoidal. The concept of someone powering their EVSE (right back to the substation) from a in car inverter is not comforting

[@Peaches_NZ]

I believe it depends on what inverter the car has onboard as to what voltage freq and wattage the car can output

[@TheBackyardChemist]

So like, these cars all have an entire separate grid-tie inverter in them, just doing squat expect when you happen to use V2L? Or are they somehow repurposing the motor inverter with minimal extra circuitry? The plug does have 3 phases, it would be epic if the motor inverter could output 3 phase. Imagine if you could just send in PWM on the CP pin and get a 3-phase VFD output.

[@JulianIlett]

Just a regular pure sine inverter, not grid tied.
