The Department of Electronic Technology from the University of Seville (Tecnología Electrónica de la Universidad de Sevilla), as part of a consortium led by ADIF, Spain’s Administrator of Railway Infrastructures (Administrador de Infraestructuras Ferroviarias), is developing a recharging system for electric vehicles that will use surplus energy from commuting and subway train networks.
In commuter train substations, fed by continuous electrical tension, a new rail technology is taking advantage of regenerative braking. This returns part of the kinetic energy from the train itself to the overhead line as electrical energy derived from the braking process. However, if this energy is not utilized immediately it is lost due to resistance.
The aim of this research project called Ferrolinera 3.0 is to be able to use this surplus energy for rapid vehicle charging systems (storage systems based on supercapacitors and batteries) so that this energy is not lost. Instead, it is stored in order to charge any electric car in only 20 minutes at charging stations available in rail substations and commuter rail stations.
Even though an electric vehicle does not produce contaminating emissions while in operation, it does consume non-renewable resources to a greater or lesser extent due to the energy that must be generated for it to move about.
This new technique contributes to sustainability by taking advantage of clean electrical energy that the railway system produces in the braking process, a technology similar to that already utilized by Formula 1 cars (supercapacitors). In this manner rail facilities can contribute to energy efficiency.
