End of life cells will never be directly reused in any form of safety critical application like that. It's simply too dangerous to deal with the voltage and discharge irregularities that come after so many cycles. They will have to be remanufactured from raw materials.
- flir 4y agoIsn't there a large gap between "no longer cost-effective for mobile applications" and "end of life"?
- ramesh31 4y ago>Isn't there a large gap between "no longer cost-effective for mobile applications" and "end of life"? Not for lithium batteries. They have a significant change in voltage (internal resistance) and charge/discharge curve that is unique to each individual cell, based on the specifics of it's lifetime usage. That makes any form of safety critical application impossible. You cannot build a pack around cells with unknown or variable properties. Sure they could be used for hobby projects or DIY stuff, but that's about it.
- asah 4y agothere's no way to sample the behavior then build an algorithm around it?
