1. A charger for aeronautical maintenance equipment, said charger comprising:
at least one high-frequency input electrical connector comprising a plurality of supply pins able to receive a three-phase AC voltage delivered by an external power source at a frequency of 400 Hz, and two detection pins,
a high-frequency charging module connected to said at least one high-frequency input electrical connector and for being connected to an electric energy storage module of said aeronautical maintenance equipment, said high-frequency charging module configured to convert the AC voltage received on the plurality of power supply pins of the at least one high-frequency input electrical connector into a direct current voltage to charge said storage module,
a control module configured to generate a detection voltage across the detection pins of the at least one high-frequency input electrical connector for the external power source, upon detecting said detection voltage, to allow supply of the AC voltage to the plurality of supply pins of the at least one high-frequency input electrical connector, and
wherein the control module is configured to receive a set point from a monitoring module of the storage module and to regulate the DC voltage supplied by the high-frequency charging module depending on said set point.
