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
First Claim
1. Electric charging system of a plurality of electric vehicles, said system comprising:
- an electric power supply suitable for delivering a maximum electric power,a plurality of charging points, each being suitable for being connected to an electric vehicle and recharging a battery of said electric vehicle, and delivering a plurality of electric power levels, each charging point being connected, via a corresponding electric line, to the electric power supply,for each charging point, a control device for controlling the electric power level delivered by the charging point to the electric vehicle connected thereto, the control device being suitable for transmitting a control signal to the corresponding charging point, said electric power level delivered being dependent on said control signal,characterised in that the control devices are connected to each other by communication links, in that at least one of the control devices generates charging tokens suitable for circulating between the control devices on the communication links, at each charging tokens being associated a partial power, corresponding to a subdivision of the maximum power and the sum of the partial powers associated with the charging tokens being less than or equal to the maximum power, and in that the control devices are suitable for controlling, using the charging tokens, the distribution of the maximum power between the charging points as a function of time and the number of electric vehicles connected to the charging points and requiring charging.

Abstract
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.

8. Method for distributing the electric power delivered by an electric power supply of an electric charging system of a plurality of electric vehicles, the electric power supply being suitable for delivering a maximum electric power, the charging system comprising:
- a plurality of charging points, each being suitable for being connected to an electric vehicle and for recharging a battery of said electric vehicle, and for delivering 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 for controlling the electric power level delivered by the charging point to an electric vehicle connected thereto,
the method comprising the following step; a) transmission by each control device of a control signal to the corresponding charging point, said delivered electric power level being dependent on said control signal, characterised in that the method comprises the following steps; b) establishing communication between the control devices via communication links; c) controlling by means of the control devices the distribution of the maximum power between the charging points as a function of time and the number of electric vehicles connected to the charging points and requiring charging, in that during step b) charging tokens are generated, in that during steps b) and c) the charging tokens circulate between the control devices on the communication links, and in that each charging token is associated with a partial power, corresponding to a subdivision of the maximum power, the sum of the partial powers associated with the charging tokens being less than or equal to the maximum power. - View Dependent Claims (9, 10, 11, 12, 13, 14)
- a plurality of charging points, each being suitable for being connected to an electric vehicle and for recharging a battery of said electric vehicle, and for delivering 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 for controlling the electric power level delivered by the charging point to an electric vehicle connected thereto,
