Abstract
A power supply system for an electrically propelled vehicle equipped with electric traction motors and including an autonomous power supply system which can be recharged on board the vehicle for supplying power to the electric traction motors. At least one station is provided with an electrical power supply system connected to a mains electrical power supply network and connection arrangements for electrically connecting the autonomous power supply system of the vehicle to the power supply system of the station, on approaching the station, in order to charge the autonomous power supply device when the vehicle is stopped in the station. The autonomous power supply system on board the vehicle includes a battery of supercapacitors and the power supply system of the station includes an energy accumulating kinetic system.
