Abstract
A device for enabling an accumulator to be recharged from a source of electrical energy, such as photo-cells. The device includes a converter circuit and a diode, the converter circuit being capable of adapting the current and voltage supplied by said source to the charging conditions of the accumulator. The converter circuit is arranged to be saturated from a certain value of the current delivered by the source, the stronger currents passing directly through the diode.
