Battery second life

While EV batteries have been shown to last for hundreds of thousands of kilometres, they will eventually fail to provide enough power and range to be useful for mobility. Yet they may still have up to 80% of their original capacity, allowing them to have a second life as stationary batteries powering applications that are less demanding than EVs. Second-life batteries are significantly cheaper than new batteries, thus making stationary storage less expensive.

Second-life applications can extract significant amounts of value from used EV battery packs before they need to be recycled; this in turn will lower the overall costs of operating a renewables-based power system.
