Abstract

Un procédé pour contrôler la charge d’un appareil mobile depuis un autre. En effet, certains appareils mobiles ont des ports usb host ou otg. Ces ports peuvent être utilisés pour charger d’autre appareils mobiles si la capacité de la batterie le permet. Toutefois, ce procédé peut être dangereux pour la batterie qui risque de se décharger trop rapidement et provoquer une surchauffe. Notre procédé permet de régler cette problématique.A method of controlling the charge of one mobile device from another. Indeed, some mobile devices have usb host or otg ports. These ports can be used to charge other mobile devices if the battery capacity permits. However, this process can be dangerous for the battery which risks discharging too quickly and causing overheating. Our process makes it possible to resolve this problem.
