A method of adjusting the power absorbed by at least one vehicle powered by at least one electrical energy storage unit and one electrical network on the ground providing the vehicle with at least one inrush current necessary for starting up the vehicle, includes adjusting the inrush current, before and at least during the starting-up of the vehicle, to a constant mean value and keeping variations of the inrush current around the mean value to a minimum by controlling at least one variable supply of compensating energy from the energy storage unit of the vehicle. A computer for implementing the method is also provided.

Method of adjusting power absorbed by at least one electrically powered vehicle

A vehicle is supplied by a first electrical energy storage unit on board the vehicle, and a ground electrical network providing an energy supply by application of a supply voltage through electrical distribution. The first energy storage unit is controllable under a generator regime or a receiver regime. The supply voltage is adjusted, in the generator regime, by applying an algebraically additive supply voltage originating from the first electrical storage unit to the distribution, to maintain a supply voltage above a minimum threshold. In the receiver regime, if a surplus of supply voltage originating at least partially from a second storage unit in the generator regime is detected above the minimum threshold, this surplus is channeled energetically to the first energy storage unit of the vehicle if it is required for operating the vehicle and enables maintaining the supply voltage below a maximum threshold and above the minimum threshold.

Method of adjusting the electrical supply voltage for the operation of at least one electrically powered vehicle

The invention relates to a power adjustment system adapted for powering an electric line for supplying power to vehicles moving in a traffic lane combined with said electric line that comprises an electric supply feeder (AD) delivering an average electric power directly or via at least one converter to the electric line, and an adjustable power based on power fluctuation and required for an instantaneous traffic intensity to an energy storage means (MS) capable of powering the electric line at a peak power via at least one other converter, characterised in that a dimensioning unit (PCC) receives information on the power needs based on the traffic intensity evaluated over at least one duration of said traffic, and in that the dimensioning unit uses information for controlling an adjustment of the useful predictable storage of the storage means so that the electric power (P_IN, P_IN) delivered to the storage means is adjusted and minimal while exactly maintaining a sufficient energy backup in the storage means for compensating for any peak power (P_INST) instantaneously required by the traffic in the given duration.
