The EASIEST way to connect used EV packs to grid! 🔋

[mwahlgreen]

Very nice.
Remember to protect the wire reduction with a fuse at the point where you have the reduction

That's a very great idea for old ev batteries.
Kudos to the programmer, that's how open source works =)

Thanks for sharing this, its suddenly a lot more attractive to do a battery upgrade in older leafs when the old battery can be re-used as is. Much love!

Dude, I am adding you to "My Hero's" list!!!

This is outstanding work! You've pretty much solved the issue I have for my enormous project!!!

[pierrex]

That's awesome. If your house is well insulated and don't live in a mansion, some version of this is probably all you need. Brilliant.

I start using Nissan leaf battery for my solar 48-volt system since 2014, you know what? 3 years ago, I bought 2 used Nissan leaf battery and dissembled them to built 16 - 48 volt stack battery bank and now this concept that is wonderful, I no longer need to dissemble. All I need now the inverter will work with this concept, my Growatt have few years on it, its time to looking at the replacement and new idea to get free energy from the sun, my current system is 2 Growatt 5k inverter, 16 Nissan leaf̣ (48volt stack), 10KA industrial transformer to convert 230V into 110V. You are right used Nissan leaf battery are not expensive like other life4 battery sell by some solar outfit

amazing setup, Dala! Fantastic work - thank you for sharing. I'm hoping to have a similar setup in my barn one day. Thanks for the inspiration!

[christopherravizza]

For the precharge resistor and that stuff you should use a cable, something like a 7G1.5 and terminate it inside the box, also why not use a microcontroller with a few relays for the startup sequence?
One last thing, put a fuse in the junction block ~32A and maybe protect the 10 mm² HV wires a little better.
Love this kind of projects, hope it keeps getting better

Came to your channel when I heard about your gracious offering to make your canbus/leaf battery swap open source and then saw this gem...very 😎!

[evanofelipe]

Thank you Dala for sharing your power storage solutions.

[wva]

Awesome stuff.. Thanks Dala for contributing to the world the way you do.

[backwoodsbungalow]

Well done, this provides an excellent second life for degraded Leaf battery pack after pack in car is upgraded. 😎 Figuring out how to make use of the Nissan electronics is so much better than spending hours dismantling a pack and then configuring a 48 volt pack. ☮️

[antronx]

Very cool stuff! Next you got to connect your Leaf direct to that inverter via DC to charge and discharge. Defeat pack to ground current leakage test module in your Leaf and you should be good to go.

[MatthewTaylorAu]

This looks easier then I was expecting. The trick will be having a compatible inverter. Now I'm keen to see other expand on this work with demonstrations for other inverters.

Thanks for posting Dala. Well done.

[gordon]

A bit more complicated than I thought but still very doable. Thank you for your work.

[RajGiandeep]

Excellent job on figuring this out. Been curious what to do with my Leaf when i get a Aptera to replace it.

[bilymotyl]

Thanks Dala, this is the kind of content I’ve subscribed for. To be able to use the car battery “as is” without messing with it, use the original BMS plus the sealed box should be really useful.

[themiddleground]

Great stuff again! I’ve been looking for a solution for a while, but most involve rearranging the cells - I even found a custom made BMS with all the connectors but it is only for the 24 kWh LEAF. This solution is much cleaner and universal!

[Ronsson]

This is amazing! Really cool, also nice to see someone from Scandinavia doing stuff like this! :D

[peteroffpist]

Will follow your update. So impressed hope to be able to install a setup like yours in the near future. So great full.
