Abstract

The invention relates to a method for controlling electric power provided at a charging station for an electric vehicle, the charging station being fed by a plant for generating renewable energy, said plant being installed close enough to the charging station that a physical and meteorological parameter value acting at the location of the plant and determining the power generated by the plant is approximately equal to the value of the parameter at the location of the charging station. The physical meteorological parameter is measured at the location of the charging station and the electric power provided by the charging station is controlled by changing a charging current as a function of the measured physical and meteorological parameter.

Furthermore, the invention relates to a charging station for an electric vehicle that implements the aforementioned method for controlling the provided electric power.
