Electric charging system of a plurality of electric vehicles and method for distributing the electric power delivered by an electric power supply of such a system

摘要

This electric charging system (10) of a plurality of electric vehicles (12) comprises, an electric power supply (14) suitable for delivering a maximum electric power, and a plurality of charging points (18). Each charging point (18) is suitable for being connected to an electric vehicle (12) and delivering a plurality of electric power levels. The system (10) comprises, for each charging point (18), a control device (20) for controlling the electric power level delivered. The control devices are connected to each other by communication links (30) and are suitable for controlling the distribution of the maximum power between the charging points as a function of time and the number of electric vehicles (12) connected to the charging points (18) and requiring charging.

主权项

1. An electric charging system of a plurality of electric vehicles, said system comprising:
an electric power supply configured to deliver a maximum electric power; a plurality of charging points, each configured to be connected to an electric vehicle and recharge a battery of said electric vehicle, and deliver a plurality of electric power levels, each charging point being connected, via a corresponding electric line, to the electric power supply; and for each charging point, a control device configured to control the electric power level delivered by the charging point to the electric vehicle connected thereto, the control device being configured to transmit a control signal to the corresponding charging point, said electric power level delivered being dependent on said control signal, wherein the control devices are connected to each other by communication links, at least one of the control devices generates charging tokens to circulate between the control devices on the communication links, each charging token being associated with a partial power, corresponding to a subdivision of the maximum electric power and a sum of the partial powers associated with the charging tokens being less than or equal to the maximum electric power, and the control devices are configured to control, using the charging tokens, the distribution of the maximum electric power between the charging points as a function of time and a number of electric vehicles connected to the charging points and requiring charging.
