To store and handle energy in vehicles and other mobile devices is a challenging task. At Uppsala University, Sweden, a flywheel is developed to fulfill the energy and power demands on an energy storage for vehicles running short distances but requiring high power. This flywheel is simulated being the energy storage in a MagLev train developed at the Federal University of Rio de Janeiro, Brazil. The train is going back and forth on a 200 m long track, requiring around 300 kJ and 37 kW. Results show that the introduction of a flywheel in the train reduces the energy consumption by 45% if the train doesn't have regenerative braking implemented. If regenerative braking is implemented the energy saving is small or absent but there could be other, more qualitative, advantages such as no need of transmitting power back to the grid, a significant lower power demand from the grid and no need for power transmitting equipment along the track.
