The federal government’s successful incentive program for zero-emissions vehicle purchases is running out of money and not slated for renewal, much to the dismay of environmental and industry groups.
Used EV cells are already starting to find use in industry. In Japan, Nissan resells pairs of used Leaf batteries that pass their testing inside an inverter pack that can provide emergency power or as a generator replacement. On top of that, they have repurposed 16 Leaf EV batteries to provide backup for and smooth out fluctuations from a solar power array in Japan. And Canada’s own Moment Energy specializes in building grid-scale storage from used EV batteries.
Work in this area is admittedly low right now — but mostly because in the 15 years since the first readily available commercial EVs started shipping, the vast bulk of them are still on the road today. So EV battery supply is pretty low right now (I’d imagine mostly being from EVs that have been in accidents which haven’t affected the battery itself). But with EV adoption increasing that supply will also increase, albeit with a 15 - 20 year lag.
And the motors don’t really ever wear out. I have no doubt some company out there will start using them for small-ish wind turbines once a reliable second hand supply is available. I agree for now that’s most likely to be in the domain of hobbies to, but if it becomes easy to source hundreds of EV motors cheaply that I don’t see why they wouldn’t be used to create small, and relatively inexpensive power stations for remote communities.
The possibilities are pretty huge here. On top of that, once these second-life uses for EV batteries and motors have finally exhausted their usefulness, they’re 95+% recyclable into new battery packs and motors, allowing the cycle to begin anew. It’s pretty exciting stuff — which is why I’m hopeful long term that the Canadian governments investments into both mineral mining and battery production pay off — EVs are just the tip of that iceberg.

(Here’s an example of a Canadian company that resells used EV batteries and motors for use in DIY projects).
