Title
(EN) CORDLESS POWER SYSTEM
(FR) SYSTEME ELECTRIQUE SANS FIL
Abstract
(EN)
A cordless system has cordless system components that include a cordless device, such as a cordless power tool, a battery pack and a charger. The battery pack is mated with either the cordless device to provide power to operate the cordless device or to the charger to charge the battery cells in the battery pack. In an aspect, the cordless system has an identification and communication system by which the battery pack identifies and communicates information about the battery pack to the cordless device or to the charger to which the battery pack is mated. In an, the battery pack of the cordless system is capable of multiple modes, such as controlling the cordless device and controlling the charger. In an aspect, the battery pack validates the cordless device or charger to which it is mated. in an aspect of the invention, the cordless system uses any of a wired interface, radio frequency interface, an optical interface or a magnetic interface to communicate information between the battery pack and the cordless device or charger to which the battery pack is mated. In an aspect, female terminals are used in a terminal block of the battery pack to protect against foreign objects contacting the terminals. In aspect, the terminals in the terminal block of the battery pack are staggered or scattered to reduce the likelihood of a short circuit. In an aspect of the invention, the battery pack has a trap door that closes when the battery pack is not mated to a cordless device or charger to protect the terminal block of the battery pack. In an aspect of the invention, multi-spring, split contact terminals are used in the terminal block of at least one of the cordless system components. In an aspect of the invention, the battery cells are Lithium Ion battery cells.
(FR)
L'invention concerne un système sans fil comprenant des composants de système sans fil qui incluent un dispositif sans fil, tel qu'un outil électrique sans fil, un bloc-batterie et un chargeur. Le bloc-batterie est couplé au dispositif sans fil en vue de la fourniture d'une énergie destinée à mettre en oeuvre le dispositif sans fil ou au chargeur en vue de la charge des éléments de batterie dans le bloc-batterie. Dans un aspect, le système sans fil comprend un système d'identification et de communication au moyen duquel le bloc-batterie réalise une identification et communique des informations sur le bloc-batterie au dispositif sans fil ou au chargeur auquel le bloc-batterie est couplé. Dans un aspect, le bloc-batterie du système sans fil présente plusieurs modes, tels que la commande du dispositif sans fil et la commande du chargeur. Dans un aspect, le bloc-batterie valide le dispositif sans fil ou le chargeur auquel il est couplé. Dans un aspect de l'invention, le système sans fil utilise une interface câblée, une interface radiofréquence, une interface optique ou une interface magnétique pour communiquer les informations entre le bloc-batterie et le dispositif sans fil ou le chargeur auquel le bloc-batterie est couplé. Dans un aspect, des bornes femelles sont utilisées dans un bloc de bornes du bloc-batterie en vue d'une protection contre les corps étrangers risquant de toucher les bornes. Dans un aspect, les bornes dans le bloc de bornes du bloc-batterie sont étagées ou dispersées en vue d'une réduction du risque de court-circuit. Dans un aspect de l'invention, le bloc-batterie comprend une trappe qui se ferme lorsque le bloc-batterie n'est pas couplé à un dispositif sans fil ou un chargeur en vue d'une protection du bloc de bornes du bloc-batterie. Dans un aspect de l'invention, des bornes de contact divisées multi-ressorts sont utilisées dans le bloc de bornes de l'un au moins des composants du système sans fil. Dans un aspect de l'invention, les éléments de batterie sont des éléments de batterie ion-lithium.
