Method and system for electric vehicle charging

Abstract

Method and system for electric vehicle charging The electric charging method is implemented by a system comprising a supervisory module, a plurality of charging stations and a compensation device adapted to inject a compensation current into the distribution network, each charging station being configured to communicate with the supervisory module via a communication link, the method comprising obtaining, from each charging station, a spectral representation of the current consumed by the station, a determination (72) of an overall spectral representation of the charging system from the spectral representations of the current consumed per charging station and per spectral rank, a calculation (75) of at least one parameter of at least one compensation current, as a function of the overall spectral representation and at least one predetermined power factor degradation threshold.The compensation current is injected into the electricity distribution network.
