Seriously cool usefulness from an old EV which most people think of as outdated ! Excellent experiment! I bet there is another interlock between Chademo and J1772 that won’t allow both to be active at the same time. I also bet you will figure it out! Love your stuff, thank you !
Outdated? Here in Europe the i-Miev and its clones are very much indispensable, if you got narrow medieval driveway then there is very little choice of small EVs currently on the market. For example Vatican uses them as police cars around St. Peter’s
Any chance you could tag where you got the 3D model? The one I got online is not quite right 😑 and I'm terrible at modeling. I'm attempting this with my Nissan Leaf; I'm so close I can practically zero my electric meter! Question: did you end up needing the pre-charge chademo circuit from the car going into the mppt or did you trust a fast blow high voltage DC fuse?? Thanks again for the help & great project videos!!!!
I got the model for the CHAdeMO connector from Thingiverse: www.thingiverse.com/thing:121581 In the description there, there are links to more details on building the connector beyond the plastic - all the electrical connectors, etc. I used solid copper 9mm rods for the main power connections and nickel-plated them. YES, I used a pre-charge resistor between the car and the input of the solar inverter. I have some parts from a Nissan Leaf battery pack, so I literally used a contactor and resistor from that, which are already perfect for 360VDC. Make sure to use some good high voltage fuses. I've already blown a few - once by not pre-charging right, once by hooking something up wrong. Take appropriate safety precautions around high-voltage DC.
@@BenjaminNelsonX thank you so much! And for sure safety is first with all appropriate PPE ☺️👍 Keep producing great videos & projects! I'll keep watching 🙏
Are you planning to upload videos on your process? As an owner of two Leafs, a gen 1 battery pack, and retired solar installer, I'd be really interested in how you trigger the DC contactor. I wonder if the Leaf will disable the charge port when the DC contactor is enabled?
good evening Benjamin! were you able to make a signal for chademo via kan so that you can connect a solar inverter? and the Chademo port was able to deliver 400 volts. If not, can you tell me who made it and can I buy it from him?
I don't know that I'd say "less complex". If you know the correct CANBUS signals and can generate them, that's the "best" way to operate the CHAdeMO. For me personally, I know little about CANBUS and certainly don't know exactly how to figure out those signals and generate them. If anyone does, please let me know!
@@BenjaminNelsonX sure that is correct however what I was referring to was the vast number of existing CHAdeMO based solutions already available from existing Japanese market place.
Yes, a commercial solution, designed by somebody else is "simpler". I've also not found an affordable 120/240V 60Hz unit available here in the United States.
What process did you use to figure out how to do the hack? I mean when you started you didn't know anything about the hack. Were you able to get some schematics or how did you end up learning how to do the hack? so we can use the same technique for our cars.
It was just by doing some reading on forums. The relay is under the back seat and it's easily identifiable. myimiev.com/forum/viewtopic.php?t=2001&start=40
This is excellent, nice work. I keep looking out for something like this but it feels like a gap in the market to make an affordable bi-directional charger that has DC terminals for connection to solar inverters. Wondered if perhaps there was some catch getting dc out, but you've proven it works. Probably needs a EVSE manufacturer to get on board. Victron would be perfectly placed to make this since they make EVSE and inverters.
@@BenjaminNelsonX thanks, that looks cool, imagine it will cost and arm and a leg due to having the inverter built in too, but nice to see that this direction is being developed
Really interesting, I’m off grid with a battery and solar system. I’m looking at getting an MG4 and am hoping I will be able to charge my home battery system from it. Are you aware of if it would effectively work the same as your system?
I don't think MG4 has the right protocols and hardware to enable bi-directional charging unfortunately. Currently this is only for cars with Chademo connectors, with a few exceptions for cars that have inbuilt bidirectional AC inverters, such as the Hyundai Ioniq 5 (using their V2L connector), and bidirectional CCS with the Ford F150 lighting. Hopefully we will see more manufacturers integrate what ford and Hyundai has done, but for now it seems like we are quite far away from lower cost manufacturers integrating it, as it's not really a selling point for them.
I'm curious what happens if or when the gridtie microinverters puts out more AC than the house loads at the time, meaning the H6 inverter would see zero net AC load, and then what? Does the H6 shifts freq or something, what makes the micros drop off?
At that point, the voltage pushes up, the micro-inverters see that as the grid going out of spec, so they turn off. They will try to reconnect again in five minutes.
Really interesting video! Crazy how many different benefits Solar energy has! Speaking of which, there is an article you may like about vehicle-to-load (V2L) on our blog! I would attach a link but my comment would get deleted for spam!⚡🔌🌍
A Nissan Leaf was also designed with the idea of being able to draw power OUT through the CHAdeMO connection. However, you would also need to know where in the car the relay is to be able to activate the battery pack contactors, or use dedicated equipment that can do that for you.

Hi Ben! I own an outlander and would like to charge faster at home. Is a diy chademo charger ac2dc a project that interests you?
good evening Benjamin! were you able to make a signal for chademo via kan so that you can connect a solar inverter? and the Chademo port was able to deliver 400 volts. If not, can you tell me who made it and can I buy it from him?
You're a cleaver fellow Mr Nelson. Thanks for posting such great information. The Nissan Leaf power I/O is software driven, so less complex.
I don't know that I'd say "less complex". If you know the correct CANBUS signals and can generate them, that's the "best" way to operate the CHAdeMO.

Enphase is now teasing that they are coming out with a bidirectional EVSE!

hi thanks !!! good job, is it possible with a nissan leaf ?
A Nissan Leaf was also designed with the idea of being able to draw power OUT through the CHAdeMO connection.

@@BenjaminNelsonX ok thanks, are you find the Relay in c-zero or Peugeot ion? IS it identical at i-miev ?
you're wrong, it IS a perpetual motion machine!
