Second-life EV batteries find use in railway crossings

Eventually the battery packs at the heart of electric cars are going to reach the end of their useful lives, but their story doesn’t necessarily end there. They can still retain enough charge for other applications, such as energy storage, boating and even classic car conversions. Now Nissan has found another use for such batteries, replacing lead acid units in emergency power supplies at railroad crossings with second-life Leaf batteries – something the company says was previously unheard of.
