Wait... Nissan LEAF Battery Replacement Just Went OPEN SOURCE!?
206,802
Published 2023-06-21
To date, that process has either involved paying a Nissan Dealer a small fortune to have the battery pack replaced with an identical-spec one to that fitted in the car when new; or paying a specialist to replace the battery pack with a newer one from a salvage LEAF.
That latter process has relied on reverse-engineering of the Nissan LEAF's CAN bus and developing a hardware and software solution that allows older LEAFs to happily work with more modern LEAF packs. And that reverse-engineering is reflected In the costs associated with asking a specialist to replace the battery pack.
But now Daniel (Dala) of Dala's EV Repair in Finland has announced that he's open-sourcing the technique he's used to successfully upgrade customer's LEAFs to larger, newer packs.
Here's why that's a MASSIVE deal, and could dramatically lower the cost of LEAF battery replacements.

This should be a requirement of all EV manufacturers. Upgrade battery capabilities must be made compulsory.
-
Thank you so much Nikki for featuring the LEAF upgrade efforts 🙏 CCS next! 😎
-
I do believe the most likely way to keep our oldest EVs on the road will be third party battery packs. The vehicle manufacturers likely won't find it as profitable to update their battery packs, similar to how our cellphones are nowadays. Hopefully, manufacturers will always make their battery packs removable, unlike our modern cellphones.
-
We need more of this to keep reusing before recycling. We need more battery replacement options for more makes before they end up in recycling.

Yep, Dala is awesome! It's definitely not an easy decision to take a lot of work and make it open source when he could be making some money off it. But this is definitely great news for Leaf owners of current and future time.
-
Woot! Dala’s channel is super cool! This seems like a fun thing to do. I hope this goes well for him. I look forward to his whole pack usage as stationary storage.
-
Truly great that this guy has open sourced his solution.

I have Leaf 2016, 30kWh, 250.000km and the battery has about 60% SOH. That would be fine, if it would be useful in winter. So I asked our official Nissan dealer for replacement. He politely told me to scrap the car and buy a new one, since the battery cost is in range of 30.000€. Yes, not a typo. So, if this is green, then I'm a hippo. Dala is such a nice guy, his work will help many, maybe even me. Thank you for this informational video.

Dala is doing a great job and has earned my patreon support. Good news for the Leaf community
-
I had a 30 put in my 2011 Leaf by Cleevely during lockdown. So far, so good. The CAN bridge came from Muxsan. Dala has always responded to my emails and is super helpful. He’s also boosted his leaf power up to 200kW.

Nikki, Champion of EVs for the common folk! Thanks for your vigilance on this.
-
I'm glad Dala is doing what he's doing. Personally, I'd be way too afraid to mess with electricity, but some people would be competent to do this kind of work.
-
I'd love to see another visit to the LEAF shop in PDX and the work they're doing on refurbishing old LEAFs for new owners. Especially when it comes to 2011-2012 cars with the flawed onboard chargers.
-
Most Leaf owners cannot do swaps themselves. Our social enterprise (nonprofit) offer this service to Leaf owners, in Ireland. The owners purchase the used battery pack themselves and we install using LeafSpy battery matching and Muxsan CAN-bridge. Next: an amazing Dala project offers "plug and play" integration of the old Leaf pack in a solar installations. Brilliant.
-
Really great to hear that this is now a thing! Well done Dala. Will have to check them out
-
That is really cool. Open source? I love all things open source, that is just too awesome. Honestly, and I say this with my bias as a gamer, but if you have something that is open source or easily modded, you'll have a community of enthusiasts who can keep something alive.
-
I’m so psyched about this! Thank you Dala for going open source and making this happen!
-
Wow thanks for sharing. Have a 2023 and totally could do this kind of work just knowledge is power thanks my frewn
-
I bought s 2015 Leaf with a new traction battery, ive had it a week and ive already started planning battery and inverter upgrades. It helps that ive been buildong c-max packs for aftermarket equipment for several years and own all the fun special tools like osciliscopes, hydraulic crimping machine, TIG welder, ect. Actually, i have a 12' x 8' enclosed trailer stocked with tools for this stuff.

Excellent video, Nikki. I've been following Dala's YouTube channel for awhile. He's also put out a few videos on Mitsubishi i-MiEV (Citroen CZero & Peugeot iOn in Europe) repairs and upgrades, which hits home for me keeping those running, as my example celebrates its 11th birthday this summer. Let's keep these older EVs functional and viable options for used car buyers on a budget for as long as we can.
