Abstract

L'alimentation électrique autonome de petits appareils électriques fait intervenir divers dispositifs connus s'avérant peu pratiques, affublés de grandes durées de chargement ou adaptés à un seul appareil. Le dispositif d'alimentation électrique autonome selon l'invention repose sur un concept modulaire selon lequel un module de générateur autonome en énergie est connecté à des modules d'accumulateur/électroniques interchangeables, spécifiques aux appareils, dans lesquels un accumulateur supplémentaire adapté à l'appareil est chargé rapidement.
