Here in the Cook Islands, I am particularly interested in solutions to the growing number of older EVs, particularly 2011 to 2013 Nissan Leafs, with batteries approaching the end of their useful life in powering the cars, which are otherwise in excellent condition. I would estimate we have about 10 of these, and will have about 30 at this stage within the next 12 months.

How to get affordable replacement batteries is one issue. I believe in NZ you can get a refurbished battery for $5000 to $6000, though they are not that common. New replacement batteries are over $20,000.

The other issue is how to deal with the old batteries.

Apparently the old batteries are still useful as energy storage for household use in conjunction with solar panels, though we would probably need some technical advice on how that works.
