NOVELTY - The system has a high-power electrical storage unit (SC-INT) such as super capacitor, placed in a vehicle (V) e.g. train. The energy recovered during braking of the vehicle is stored in the storage unit. A departure station (S1) has an electrical loading area (CHARGE-AREA) for loading the storage unit and activated in a loading mode when the residual energy of the storage unit is below a variable threshold dependent on an early estimate of the energy balance of the vehicle up to an arrival station, where the loading area is connected with an electrical energy source such as power grid.    USE - Used for regulating energy for a vehicle e.g. train, underground railway, streetcar, bus and other transportation unit whose paths are defined in a deterministic manner, for performing mass transportation and public transportation such as railway transportation, between a departure station and an arrival station such as railway platform, along a predetermined route.    ADVANTAGE - The system effectively minimizes the economic and environmental impact of the vehicle, and controls the energy utilized for the vehicle in a cost effective manner. The system passes power supply from the ground towards the vehicle on the loading area at a level of the station for passengers, thus avoiding the need for rails, cables or catenary linking the vehicle to the energy source at the ground between the stations, and hence eliminating the energy losses during the transmission of the power supply through the rails, cables or the catenary, avoiding the risk of electrical failure for the vehicle, avoiding the creation of the dangerous electricity for the pedestrians or various other cyclists crossing a track of the streetcar and increasing the economic performances of the mass transport or public transport.
