CA 2707183

A power tool, such as a pipe cutter, includes a rotatable cutting head assembly, an electric motor connectable to a rechargeable battery, and a controller. The controller is configured to monitor the state of charge on the battery, compare the state of charge to one or more thresholds, and prevent or limit operation of the power tool when the state of charge is less than or equal to one or more of the thresholds. In some embodiments, the threshold includes the state of charge required to cut a pipe, the state of charge required to return the cutting head assembly to a home position, and a state of charge indicative of an overdischarged condition of the battery. In some embodiments, the controller is configured to detect when the pipe cutter has completed cutting the pipe and returns the cutting head assembly to the home position.

L'invention porte sur un outil électrique, tel qu'un coupe-tube. Le coupe-tube comporte un ensemble tête de coupe rotatif ; un moteur électrique connectable à une batterie rechargeable ; et un contrôleur. Le contrôleur est conçu pour surveiller l'état de charge de la batterie ; comparer l'état de charge à un ou plusieurs seuils ; et prévenir ou limiter le fonctionnement de l'outil électrique lorsque l'état de charge est inférieur ou égal à un ou plusieurs des seuils. Dans certains modes de réalisation, le seuil comporte l'état de charge requis pour couper un tube, l'état de charge requis pour renvoyer l'ensemble tête de coupe à une position nominale, et un état de charge indicatif d'une condition de surdécharge de la batterie. Dans certains modes de réalisation, le contrôleur est conçu pour détecter la fin de la coupe du tube et renvoyer l'ensemble tête de coupe à sa position de départ.
