Few people know it, but supercapacitors are already in use in many car models for brake energy regeneration and Start-Stop systems (not only in electric vehicles). Indeed, ultracapacitors are particularly effective in meeting this need. Able to charge and discharge very quickly and almost without wear, the supercapacitor appears as an ultra-fast and reliable battery.
