Abstract: A charger operable to charge a battery of an electric vehicle from an electric power grid. The charger includes a first connector unit operable to connect the charger to the electric power grid, an AC/DC converter, a set of filters provided between the first connector unit and the AC/DC converter, a second connector unit operable to connect the charger to the battery, and a configurator provided between the first connector unit and the set of filters, the configurator being provided with a set of switches and/or relays operable to switch between a three-phase operation and a single-phase operation to charge the battery from the electric power grid.

Abstract: A method for generating a current set point value for a charging device connected to an electrical network includes measuring at least one electrical voltage, calculating a filtered voltage according to the measured voltage and a value of electrical pulsation of the electrical network, estimating a frequency and the amplitude of the measured voltage according to the at least one measured voltage and the at least one filtered voltage, calculating a consolidated voltage according to the measured voltage and the filtered voltage, and generating a current set point value according to the consolidated voltage and the estimated amplitude.
