Abstract

L'invention concerne un dispositif d'alimentation électrique (10) comprenant : un corps de dispositif, le corps de dispositif étant pourvu d'une pluralité de bases de montage de bloc-batterie (1, 2.., n), et un bloc-batterie correspondant étant monté amovible sur la base de montage de bloc-batterie ; un module de commande, qui est disposé à l'intérieur du dispositif d'alimentation électrique (10) et configuré pour commander le fonctionnement du dispositif d'alimentation électrique (10) ; et un module sans fil, qui est disposé à l'intérieur du dispositif d'alimentation électrique (10), connecté électriquement à un dispositif intelligent, interagit avec le dispositif intelligent au moyen d'une instruction, et renvoie une instruction reçue au module de commande, de sorte que le module de commande contrôle, sur la base de l'instruction reçue, le fonctionnement du dispositif d'alimentation électrique (10). Le dispositif d'alimentation électrique peut non seulement fournir de l'énergie à des dispositifs électriques (tels que des appareils électroménagers), mais peut également fournir de l'énergie à des outils électriques ayant des tensions correspondantes lorsque les blocs-batteries sont détachés. De plus, les blocs-batteries détachés peuvent en outre être utilisés dans d'autres occasions, par exemple, en servant de source d'énergie mobile pour charger le dispositif intelligent. L'expérience de l'utilisateur est ainsi considérablement améliorée.
