MITRAC Energy Saver
The intelligent MITRAC Energy Saver developed by Bombardier Transportation enables light rail vehicles to economize almost one third of their energy consumption and bridge patches without overhead lines. This Energy Saver, based on high performance double layer capacitor technology (ultracapacitors), provides vehicles with an energy source that has a considerably longer service life than energy storage based on conventional batteries. The system works by charging the ultracapacitors during vehicle braking, and releasing it when it is needed, such as when accelerating the vehicle.
