Title
(EN) CRANK-DRIVEN POWER SUPPLY
(FR) ALIMENTATION ÉLECTRIQUE ENTRAÎNÉE PAR MANIVELLE
Abstract
(EN) The invention uses charged supercapacitors to store energy in a portable hand held/cranked device to electrically charge connected electronic devices such as mobile phones or tablets. Supercapacitors are charged with energy from one of three sources; a hand cranked electrical generator, integral solar cell array and/or a connection to a local mains supply. The hand cranked electrical generator is a major component in the invention as it converts kinetic energy harvested from a user's hand rotary motion into electrical power which is then electronically regulated by a microcontroller and subsequently converted into a stable power output via an electronic regulator circuit. Power from all three energy sources can be simultaneously applied to the invention. Techniques are employed in the embodiments of the invention to manage supercapacitors condition and charge rates to optimise power transfer efficiency. The invention provides a convenient, environmentally friendly, quick and stable energy source for portable devices.
(FR) L'invention fait appel à des supercondensateurs chargés pour stocker de l'énergie dans un dispositif portable ou portatif à manivelle afin de charger électriquement des dispositifs électroniques connectés tels que des téléphones mobiles ou des tablettes. Les supercondensateurs sont chargés avec de l'énergie provenant de l'une des trois sources suivantes : un générateur électrique à manivelle, un réseau de cellules solaires intégrées et/ou une connexion à une alimentation secteur locale. Le générateur électrique à manivelle est un composant majeur dans l'invention, car il convertit l'énergie cinétique récoltée à partir du mouvement rotatif de la main d'un utilisateur en énergie électrique qui est ensuite régulée électroniquement par un microcontrôleur, puis convertie en une sortie de puissance stable par l'intermédiaire d'un circuit régulateur électronique. L'énergie provenant des trois sources d'énergie peut être simultanément appliquée à l'invention. Des techniques sont utilisées dans les modes de réalisation de l'invention pour gérer les états des supercondensateurs et les taux de charge pour optimiser l'efficacité de transfert de puissance. L'invention fournit une source d'énergie commode, respectueuse de l'environnement, rapide et stable pour des dispositifs portables.
