Braking energy recuperation in Spanish rail system
"By incorporating ultracapacitors, which accept charge from the braking energy recuperation system much more efficiently than batteries, the system recovers significantly more energy," said Eugenio Domínguez Amarillo, Win Inertia's CEO and chief technology officer. "Additionally, by using ultracapacitors to relieve the batteries of the stress of repetitive cycling, we expect to extend battery life by 20 to 25 percent."
Braking energy recuperation systems in electric and hybrid rail vehicles save fuel and electrical energy by using resistance from the electric motor to stop the vehicle, and, through that process, converting kinetic energy that would be wasted in a conventional friction-based braking system into stored electrical energy. Ultracapacitors' high reliability and extremely long operational life also make them a preferred option for heavy cycling electric utility grid applications.
Dr. Franz Fink, Maxwell's president and CEO, said, "Transportation is the world's largest energy consumer, so systems that enhance energy efficiency and reduce fossil fuel consumption and emissions can play a transformational role in energy management and create tremendous long-term growth opportunities for rapidly advancing ultracapacitor technology."
