Title
(EN) DYNAMIC BATTERY POWER MANAGEMENT
(FR) GESTION DYNAMIQUE DE LA PUISSANCE D'UNE BATTERIE
Abstract
(EN)
Methods, systems, and devices, including machine-readable media, for dynamic battery power management are disclosed. In some implementations, an electronic device (110) that is powered by a battery (112) senses a voltage (via 116, during stage A) provided by the battery (112) and an electric current (via 118, during stage A) provided by the battery (112). The electronic device (110) determines a present state (via 114, during stage A) of the battery (112). The electronic device (110) determines a current limit (during stages C and D) for the electronic device (110) based on the sensed voltage (via 116, during stage A) and electric current (via 118, during stage A) and the determined present state (via 114, during stage A) of the battery (112). The electronic device (110) manages power use (via 130, during stage E) of the electronic device (110) to maintain electric current draw from the battery (112) at or below the electric current limit.

L'invention concerne des procédés, des systèmes et des dispositifs, y compris des supports lisibles par machine, pour la gestion dynamique de la puissance d'une batterie. Dans certains modes de réalisation, un dispositif électronique (110) qui est alimenté par une batterie (112) détecte une tension (via 116, durant la phase A) fournie par la batterie (112) et un courant électrique (via 118, durant la phase A) fourni par la batterie (112). Le dispositif électronique (110) détermine un état présent (via 114, durant la phase A) de la batterie (112). Le dispositif électronique (110) détermine une limite de courant (durant les phases C et D) pour le dispositif électronique (110) en se basant sur la tension détectée (via 116, durant la phase A) et le courant électrique (via 118, durant la phase A) et l'état présent déterminé (via 114, durant la phase A) de la batterie (112). Le dispositif électronique (110) gère l'utilisation de la puissance (via 130, durant la phase E) du dispositif électronique (110) en vue de maintenir le courant électrique prélevé de la batterie (112) à un niveau inférieur ou égal à la limite de courant électrique.
