Abstract

La présente invention concerne un système de charge embarqué comprenant une première batterie (10), une seconde batterie (20) connectée en série à la première batterie (10), ainsi qu'une dynamo à courant alternatif (M/G) conçue pour charger ces première et seconde batteries. Un point intermédiaire (15) où la première batterie et la seconde batterie sont connectées est réglé au même potentiel qu'une extrémité de la dynamo à courant alternatif. Un premier redresseur (D1) qui redresse de la dynamo à courant alternatif à la borne plus (+) de la première batterie (10) est intercalé entre la dynamo à courant alternatif et la première batterie. Un second redresseur (D2) qui redresse de la borne moins (-) de la seconde batterie (20) à la dynamo à courant alternatif est intercalé entre la dynamo à courant alternatif et la seconde batterie. Un courant alternatif produit par une dynamo à courant alternatif est redressé en deux types de courant de sens différents et les deux batteries sont chargées individuellement de manière répartie dans le temps avec ces courants redressés. Le système de charge de batterie selon cette invention permet ainsi de charger les deux batteries avec une dynamo.
