Abstract

L'invention appartient au domaine des dispositifs d'accumulation et de stockage d'énergie électrique et notamment de chargement de téléphones mobiles en mode autonome. La source de tension autonome comprend un convertisseur photoélectrique connecté à une batterie via une unité à diodes et condensateurs. Une diode lumineuse est branchée en parallèle à la batterie via un interrupteur. Une diode Schottky est branchée entre la batterie et la prise de la sortie de tension positive. La source d'alimentation autonome comprend également un régulateur élévateur de tension destiné à assurer une tension de chargement suffisante qui alimente la batterie. L'invention permet de commencer et de terminer le chargement de la batterie en mode d'économie et d'effectuer le chargement d'un téléphone mobile dans le noir ou à la lumière du jour; elle permet d'assurer l'alimentation dans un sens en provenance du convertisseur photoélectrique vers la batterie, grâce au fait que l'unité à diodes et condensateurs est constituée d'un condensateur branché en parallèle au convertisseur photoélectrique et de deux diodes Schottky rapides dont la première est branchée en série entre le convertisseur photoélectrique et le condensateur, et la deuxième est branchée entre le condensateur et la batterie d'alimentation du côté de sa sortie positive.
