Braking energy recuperation in Spanish rail system
Maxwell Technologies, Inc has announced that Win Inertia, an engineering firm specializing in power electronics, energy storage and control and communication systems, is using its ultracapacitors for a stationary wayside braking energy recuperation system at an electric rail system in Cerro Negro, Spain. Win Inertia designed and installed the system under a contract with the Spanish government's Administrator of Railway Infrastructures (ADIF). In this installation, the system also enables ADIF to store excess energy in a battery bank that supplies an electric vehicle (EV) charging station located at the rail station. The facility also seamlessly integrated a photovoltaic (PV) generator to supply additional energy if required.
The recuperation system employs Win Inertia's SHAD® hybrid control technology (international patent pending) to integrate batteries and Maxwell ultracapacitors to increase energy recovery efficiency and reduce stress on the batteries, thereby extending battery life. Ultracapacitors' rapid charge/discharge characteristics uniquely enable them to capture and store more energy during each braking event than battery-based systems, which have limited ability to absorb energy in the few seconds required to stop a vehicle. Win Inertia's high-efficiency hybrid energy storage and power delivery system furthers ADIF's return on investment as it enables dual use of the recuperated energy for rail vehicle propulsion and EV charging. By converting kinetic energy into stored electric energy through regenerative braking, the system recovers 8 to 10 percent of the total energy used by the railway system, which is then used to power the EV charging station.
