Sell a PowerWall type thing made with a single 60/70/85KwH pack pulled from a vehicle after its downgraded to ~70% capacity. design your vehicle packs from day one for a second life as stationary energy storage, where size and weight don’t matter.
- yowlingcat 6y agoI think this kind of circular EV economy is the real big money logistics idea. There is, as you've astutely pointed out, no reason why this protocol shouldn't exist industry-wide. But, how do you solve the materials problem that closes the loop: somehow recycling old EV raw materials into new EV materials? AFAIK there still aren't great SOTA solutions to this. At some point, it's hard to have a nice closed cycle of production and waste-recyling for ecological and cost optimization purposes.
- adrianN 6y agoRight now the market for recycling EV batteries is still pretty small because there just aren't that many old EVs around. I bet recycling will increase in a couple years.
