The invention concerns a method for charging an electrical energy storage unit, in particular installed in a vehicle, from a continuous charging terminal, using a DC/DC voltage converter to adapt the voltage between said continuous charging terminal and said electrical energy storage unit, said DC/DC voltage converter comprising at least two interleaved cells operating out of phase, each cell having respective switches; said method comprising control of the switches of said DC/DC voltage converter by pulse width modulation with a duty cycle to adapt the voltage between said continuous charging terminal and the electrical energy storage unit, said duty cycle having a given value αv that is substantially constant over several interleaving cycles.
