In electric and hybrid cars, the regenerative brakes charge the main battery pack, effectively extending the vehicle's range between charges. Electric trains, which are powered by overhead or trackside powerlines, work in a slightly different way. Instead of sending braking energy into batteries, they return it to the powerline. A typical modern electric train can save around 15–20 percent of its energy using regenerative brakes in this way. Some vehicles use banks of supercapacitors for storing energy instead of batteries.
