Nissan LEAF Battery Replacement Just Went OPEN SOURCE!?

From Transport Evolved.

The Nissan LEAF has been produced and sold in significant number for nearly fourteen years – and while the majority of those cars are some still happily rolling on their original, healthy battery packs many years later, others are in need of replacement packs.

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.
