1. A system for supplying extra low voltage electrical energy for at least one electrical traction vehicle (30) running on a track (20) and comprising:

  • wheels (31) linked to said vehicle and rolling on said track (20), and at least one traction chain (70) of said vehicle acting on the wheels (31) and comprising, in a manner known per se, at least one electric motor and its control, at least one extra low voltage power supply means (10) installed in the immediate vicinity of the track (20), two power supply rails (41, 42) or similar power supply elements, parallel to each other, adjacent or distant, of which a first (41) is linked to a terminal (11) of said power supply means (10) and the second (42) is linked to another terminal (12) of said power supply means (10), at least one first electrical energy collection means (51) on board the vehicle and placed in moving contact with said first rail (41), at least one second electrical energy collection means (52) also on board the vehicle and placed in moving contact with said second rail (42), at least one electrical energy storage means (60) on board the vehicle, system characterized in that it comprises at least one onboard power supply means (80) which is linked to said electrical energy collection means (51, 52), and which is connected on the one hand to said storage means (60) and on the other hand to said traction chain (70), and which controls the energy distribution from the storage means (60) to the traction chain (70) and in particular the recharging of the storage means (60) and its selective discharging to feed the traction chain (70) according to the energy demand and the rolling sequences of the vehicle.
