Have you ever noticed how your cell phone or iPod doesn’t hold a charge quite as long as it used to? The same thing can be said for any rechargeable battery – like the one used to start your gasoline- or diesel-powered vehicle, or even rechargeable batteries used for TV and video game remotes. It’s something nobody really pays attention too, but all rechargeable batteries suffer from capacity degradation over time whether they are regularly charged or not. So what does this have to do with the used car market? Well, as EVs become more popular and start becoming more commonplace, they’ll start to be treated the same way we treat fuel-powered vehicles now: drive them for a few years, then trade it in for something new. But, unlike cars with an internal combustion engine, there will be no such thing as an EV that drives and performs like new after seven or eight years of use.
