Title
(EN) METHOD OF CONTROLLING AN ENERGY HARVESTING SYSTEM
(FR) PROCÉDÉ DE COMMANDE D'UN SYSTÈME DE COLLECTE D'ÉNERGIE
Abstract
(EN)
A method of controlling an energy harvesting system, comprising providing an energy storage device (121) and a plurality of energy harvesters (111); wherein each of the energy harvesters (111) is connectable to the energy storage device (121) thereby to transfer energy to the energy storage device (121); determining a load characteristic of an energy harvester (111); and controlling a transfer of energy from the energy harvester (111) to the energy storage device (121) in dependence on the determined load characteristic.
(FR)
L'invention concerne un procédé de commande d'un système de collecte d'énergie, comprenant la fourniture d'un dispositif de stockage d'énergie (121) et d'une pluralité de collecteurs d'énergie (111). Chaque dispositif de collecte d'énergie (111) peut être relié au dispositif de stockage d'énergie (121) pour transférer ainsi de l'énergie au dispositif de stockage d'énergie (121). Le procédé selon l'invention comprend également la détermination d'une caractéristique de charge d'un collecteur d'énergie (111); et la commande d'un transfert d'énergie du collecteur d'énergie (111) vers le dispositif de stockage d'énergie (121) en fonction de la caractéristique de charge déterminée.
