This Southern California solar farm is using retired EV batteries for storing the power and then send to the grid when needed. This way the retired batteries can extend their usefulness for several…::A Southern California company is showing how repurposing EV batteries for stationary storage can extend their usefulness for several years.
At one time, they didn’t last more than a few years, and needed expensive replacement. Newer batteries have better BMS controllers on them and last a lot longer. But any damage pretty much necessitates replacement. The batteries can probably be fixed but IDK if they can be put back into use in vehicles then. So there’s plenty of used batteries that can be upgraded to use for stationary storage. You can buy them all day long on certain websites or auctions. It’s a pretty popular thing for DIY solar.
