Description

CHARGEUR DE BATTERIE, NOTAMMENT POUR TELEPHONE PORTABLE BATTERY CHARGER, ESPECIALLY FOR A MOBILE PHONE
L'invention est relative à un chargeur de batterie, notamment pour téléphone portable.The invention relates to a battery charger, in particular for a mobile phone.
Un certain nombre d'appareils d'usage courant, tels que les téléphones portables, sont alimentés par des batteries qui doivent être rechargées à intervalles réguliers. Les différents types d'appareils sont équipés de batteries aux caractéristiques très diverses, notamment pour les paramètres de charge que sont la tension de charge et le courant de charge ainsi que pour la géométrie du connecteur de liaison. Par exemple les modèles de téléphones portables sont nombreux et comprennent en général des batteries dont les caractéristiques de paramètres de charge et de connecteur diffèrent d'un modèle à l'autre. Les paramètres de charge et la géométrie du connecteur caractérisent ainsi un chargeur de batterie constituant un ensemble adapté à chaque modèle d'appareil, ce qui conduit à l'existence de nombreux types de chargeurs . L'évolution rapide des modèles d'appareil conduit à acquérir un chargeur de batterie pour chaque nouveau modèle. Cette situation entraîne des dépenses inutiles. On connaît déjà des chargeurs de batterie réglables pouvant délivrer diverses valeurs de tension et/ou courant de charge. Toutefois, d'une part, ils nécessitent un réglage de la part de l'utilisateur, ce qui constitue un obstacle à leur utilisation, et d'autre part, le connecteur est relié au chargeur par l'intermédiaire d'un câble pratiquement inamovible de l'appareil, ce câble se terminant par un connecteur également inamovible du câble . Ainsi, malgré la possibilité de modifier les paramètres électriques de charge, ces dispositifs ne, sont adaptés qu'à un seul type d'appareil, ou à un nombre limité de types d'appareils.A number of everyday devices, such as mobile phones, are powered by batteries which need to be recharged at regular intervals. The different types of devices are equipped with batteries with very different characteristics, in particular for the charging parameters, which are the charging voltage and the charging current, as well as for the geometry of the connection connector. For example, the models of mobile phones are numerous and generally include batteries, the characteristics of charge parameters and connector of which differ from one model to another. The charging parameters and the geometry of the connector thus characterize a battery charger constituting an assembly adapted to each model of device, which leads to the existence of many types of chargers. The rapid evolution of device models leads to the acquisition of a battery charger for each new model. This situation results in unnecessary spending. There are already known adjustable battery chargers that can deliver various values of charge voltage and / or current. However, on the one hand, they require adjustment on the part of the user, which constitutes an obstacle to their use, and on the other hand, the connector is connected to the charger via a practically irremovable cable. of the device, this cable ending in a connector which is also irremovable from the cable. Thus, despite the possibility of modifying the electrical charging parameters, these devices are only suitable for one type of device, or for a limited number of types of device.
L'invention remédie à cet inconvénient en mettant à la disposition de l'utilisateur d'appareils à batterie, un chargeur d'utilisation aisée et pouvant être utilisé pour plusieurs types d'appareil.The invention overcomes this drawback by providing the user of battery-powered devices with an easy-to-use charger that can be used for several types of device.
L'invention consiste à prévoir un chargeur dont les paramètres de charge sont variables et à équiper ce chargeur d'un élément de connexion à l'appareil, cet élément étant amovible du chargeur, et à prévoir un moyen, extérieur au chargeur, permettant de déterminer automatiquement les paramètres électriques de la charge lors du branchement de l'appareil au chargeur par l'intermédiaire de l'élément de connexion. Dans une réalisation préférée, le moyen de détermination automatique des paramètres de charge est solidaire de l'élément de connexion.The invention consists in providing a charger whose charging parameters are variable and in equipping this charger with a connection element to the device, this element being removable from the charger, and in providing a means, external to the charger, making it possible to automatically determine the electrical parameters of the load when the device is connected to the charger via the connection element. In a preferred embodiment, the means for automatically determining the load parameters is integral with the connection element.
En variante ce moyen de détermination se trouve dans l'appareil à batterie. Ainsi un usager ou un distributeur de chargeurs peut disposer d'un seul chargeur (ou type de chargeur) et d'une pluralité d'éléments de connexion, chacun de ceux-ci étant adapté à un modèle d'appareil.As a variant, this determination means is located in the battery device. Thus a user or a distributor of chargers can have a single charger (or type of charger) and a plurality of connection elements, each of these being adapted to a model of device.
Dans un mode de réalisation, l'élément de connexion comporte un premier connecteur destiné à coopérer avec un connecteur complémentaire de l'appareil et prolongé par un câble se terminant par un second connecteur pour la liaison au chargeur.In one embodiment, the connection element comprises a first connector intended to cooperate with a connector complementary to the device and extended by a cable ending with a second connector for connection to the charger.
Dans ce cas, si le moyen déterminant automatiquement les paramètres du chargeur se trouve dans l'élément de connexion, ce moyen peut être installé dans le câble et/ou dans le premier et/ou le second connecteur.In this case, if the means automatically determining the charger parameters is in the connection element, this means can be installed in the cable and / or in the first and / or the second connector.
Dans une réalisation, le moyen de détermination automatique des paramètres comporte au moins un composant électronique telle qu'une résistance ou une connexion tel qu'un simple fil de connexion, qui, lors de la connexion de l'appareil au chargeur constitue un composant (élément) d'un circuit du chargeur déterminant le (les) paramètre (s) de la charge.In one embodiment, the means for automatically determining the parameters comprises at least one electronic component such as a resistor or a connection such as a simple connection wire, which, when the device is connected to the charger constitutes a component ( element) of a charger circuit determining the charge parameter (s).
En variante, le (ou les) composant (s) ou l'élément (ou les éléments) , tels que des résistances, est (sont) contenu (s) physiquement dans l'appareil à batterie et le cordon de liaison électrique reliant l'appareil au chargeur de batterie comporte au moins un conducteur par composant (ou élément) en plus des conducteurs destinés à la charge. L'invention concerne donc un chargeur de batterie comprenant un élément de connexion à l'appareil dont la batterie est à charger qui est caractérisé en ce que ses paramètres de charge sont variables, en ce que l'élément de connexion est amovible du chargeur, et en ce qu'il comprend un moyen, extérieur au chargeur, permettant de déterminer automatiquement le (les) paramètre (s) électrique (s) de la charge lors du branchement de l'appareil au chargeur par l'intermédiaire de l'élément de connexion.Alternatively, the component (s) or the element (or elements), such as resistors, is (are) physically contained (s) in the battery device and the electrical connection cord connecting the The device to the battery charger comprises at least one conductor per component (or element) in addition to the conductors intended for charging. The invention therefore relates to a battery charger comprising a connection element to the device whose battery is to be charged which is characterized in that its charging parameters are variable, in that the connection element is removable from the charger, and in that it comprises a means, external to the charger, making it possible to automatically determine the electrical parameter (s) of the load when the device is connected to the charger via the element of connection.
Le moyen de détermination automatique du (des) paramètre (s) de la charge se trouve, par exemple, dans l'élément de connexion.The means for automatic determination of the load parameter (s) is, for example, in the connection element.
Ce moyen comporte, dans une réalisation, au moins un composant électronique tel qu'une résistance.This means comprises, in one embodiment, at least one electronic component such as a resistor.
Selon un mode de réalisation, le moyen de détermination du (des) paramètre (s) de la charge se trouve dans le connecteur de l'élément de connexion qui est destiné à coopérer avec un connecteur complémentaire du chargeur.According to one embodiment, the means for determining the parameter (s) of the load is located in the connector of the connection element which is intended to cooperate with a complementary connector of the charger.
Le moyen de détermination automatique du (des) paramètre (s) de la charge peut aussi se trouver dans le câble de l'élément de connexion ou dans un connecteur destiné à coopérer avec un connecteur complémentaire de l'appareil à charger.The means for automatic determination of the load parameter (s) can also be found in the cable of the connection element or in a connector intended to cooperate with a connector complementary to the device to be charged.
L'invention concerne aussi un chargeur de batterie qui est caractérisé en ce qu'il comporte des moyens pour faire varier le (les) paramètre (s) de charge et en ce qu'il comporte au moins une entrée pour recevoir un élément ou signal pour déterminer ce (ces) paramètre (s) .The invention also relates to a battery charger which is characterized in that it comprises means for varying the charge parameter (s) and in that it comprises at least one input for receiving an element or signal to determine this (these) parameter (s).
L'entrée pour recevoir un signal de détermination du (des) paramètre (s) de la charge constitue, par exemple, une entrée d'un connecteur destiné à coopérer avec un connecteur complémentaire d'un élément de connexion à l'appareil à charger.The input for receiving a signal for determining the parameter (s) of the charge constitutes, for example, an input of a connector intended to cooperate with a complementary connector of a connection element to the device to be charged .
L'invention se rapporte également à un élément de connexion destiné à relier un chargeur de batterie à un appareil à batterie qui est caractérisé en ce qu'étant amovible du chargeur, il comporte au moins un composant destiné à déterminer, dans le chargeur, le (s) paramètre (s) de la charge de l'appareil à batterie auquel il est destiné à être relié. Dans cet élément de connexion, le moyen pour déterminer le (s) paramètre (s) de la charge comporte, selon une réalisation, au moins un composant électronique tel qu'une résistance dont les bornes sont destinées à être connectées au chargeur par l' intermédiaire du connecteur de cet élément de connexion.The invention also relates to a connection element intended to connect a battery charger to a battery device which is characterized in that being removable from the charger, it comprises at least one component intended to determine, in the charger, the (s) parameter (s) of the charge of the battery device to which it is intended to be connected. In this connection element, the means for determining the parameter (s) of the load comprises, according to one embodiment, at least one electronic component such as a resistor whose terminals are intended to be connected to the charger by the the connector of this connection element.
L'invention concerne aussi un appareil à batterie susceptible d'être connecté à un chargeur de batterie par un connecteur qui est caractérisé en ce qu'il comprend un moyen permettant de déterminer automatiquement les paramètres électriques de la charge engendrée par le chargeur lors du branchement de l'appareil au chargeur par l'intermédiaire du connecteur.The invention also relates to a battery device capable of being connected to a battery charger by a connector which is characterized in that it comprises a means making it possible to automatically determine the electrical parameters of the charge generated by the charger when connecting the device to the charger via the connector.

D'autres caractéristiques et avantages de 1 ' invention apparaîtront avec la description de certains de ses modes de réalisation, celle-ci étant effectuée en se référant aux dessins ci-annexés sur lesquels: la figure 1 est une vue schématique de l'ensemble, conforme à l'invention, d'un chargeur de batterie et d'un appareil à batterie reliés par un câble de liaison, la figure 2 est une vue schématique de l'ensemble, conforme à l'invention, d'un chargeur de batterie et d'un connecteur de câble côté chargeur.Other characteristics and advantages of the invention will appear with the description of some of its embodiments, this being carried out with reference to the appended drawings in which: FIG. 1 is a schematic view of the assembly, according to the invention, a battery charger and a battery device connected by a connecting cable, Figure 2 is a schematic view of the assembly, according to the invention, of a battery charger and a cable connector on the charger side.
Un chargeur de batterie est fonctionnellement constitué par un montage électronique, branché en entrée sur le secteur ou sur une batterie de 48 volts au plus, qui délivre à un appareil à batterie à recharger, en général par l'intermédiaire d'un cordon de branchement, des paramètres de charge tels que tension et courant, ceux-ci étant déterminés par la valeur de composants du montage.A battery charger is functionally constituted by an electronic assembly, connected to the mains input or to a battery of 48 volts at most, which delivers to a device with a battery to be recharged, generally by means of a connection cord , load parameters such as voltage and current, these being determined by the value of components of the assembly.
Dans l'exemple on dispose ces composants de réglage dans un élément amovible tel que le cordon de branchement muni de deux connecteurs, on connecte chacun de ces composants à une paire de bornes du connecteur, de préférence côté chargeur, et on relie à l'intérieur du chargeur chaque paire de bornes à la position prévue pour le composant dans le schéma du montage .In the example, these adjustment components are placed in a removable element such as the connection cord provided with two connectors, each of these components is connected to a pair of connector terminals, preferably on the charger side, and it is connected to the inside the charger, each pair of terminals in the position provided for the component in the assembly diagram.
Ainsi le chargeur peut être utilisé pour la charge de divers appareils, le cordon étant particulier à chaque appareil. Le chargeur de batterie 2 , représenté sur la figure 1 présente un connecteur à deux bornes d'entrée 4 adaptées au secteur. Le chargeur de batterie 2 est relié à l'appareil 6 dont la batterie est à charger par un câble 8 comportant une pluralité de conducteurs et se terminant côté chargeur par un connecteur amovible 10 destiné à coopérer avec un connecteur complémentaire (non représenté) fixé au chargeur. Le câble 8 est équipé, du côté de l'appareil à batterie, d'un second connecteur 12 destiné à coopérer avec un connecteur complémentaire (non représenté) monté sur l'appareil 6.Thus the charger can be used for charging various devices, the cord being specific to each device. The battery charger 2, shown in FIG. 1, has a connector with two input terminals 4 adapted to the sector. The battery charger 2 is connected to the device 6 whose battery is to be charged by a cable 8 comprising a plurality of conductors and ending on the charger side by a removable connector 10 intended to cooperate with a complementary connector (not shown) fixed to the charger. The cable 8 is equipped, on the side of the battery device, with a second connector 12 intended to cooperate with a complementary connector (not shown) mounted on the device 6.
Le chargeur de batterie 2 est représenté sur la figure 2 dans une version adaptée au secteur comme source d'énergie. Il contient un montage électronique représenté sous forme de blocs comprenant notamment un bloc redresseur 13 délivrant une tension continue à un circuit 14 de découpage haute fréquence, lequel alimente un transformateur d' isolement 16 dont la sortie est connectée à deux bornes 18 et 20 du connecteur de sortie du chargeur. Les paramètres de charge, courant et tension, délivrés sur les bornes 18 et 20 sont déterminés par un signal de référence de tension 24 et par un signal de référence de courant 26. Les valeurs des signaux de référence dépendent respectivement de valeurs de résistances 28 et 30, se trouvant dans le connecteur 10 et reliées au montage électronique du chargeur de batterie par des bornes de liaison 34,36 et 38, 40. Les signaux de référence des éléments 24 et 26 sont transmis au circuit 14 de découpage par un optocoupleur 22 Ainsi le branchement du connecteur 10 au chargeur de batterie particularise ce chargeur et lui permet de délivrer sur les bornes de sortie 18 et 20 les paramètres de charge adaptés à l'appareil à batterie.The battery charger 2 is shown in Figure 2 in a version suitable for the sector as an energy source. It contains an electronic assembly represented in the form of blocks comprising in particular a rectifier block 13 delivering a direct voltage to a high-frequency cutting circuit 14, which supplies an isolation transformer 16 whose output is connected to two terminals 18 and 20 of the connector charger output. The load, current and voltage parameters, delivered on terminals 18 and 20 are determined by a voltage reference signal 24 and by a current reference signal 26. The values of the reference signals depend respectively on resistance values 28 and 30, located in the connector 10 and connected to the electronic assembly of the battery charger by connection terminals 34, 36 and 38, 40. The reference signals of the elements 24 and 26 are transmitted to the cutting circuit 14 by an optocoupler 22 Thus the connection of the connector 10 to the battery charger particularizes this charger and allows it to deliver on the output terminals 18 and 20 the charge parameters adapted to the battery device.
Dans une variante (non montrée) l'appareil à batterie transmet un signal représentant les paramètres de charge qui sont transmis par le câble de liaison amovible au chargeur de batterie qui comporte donc une entrée pour recevoir ces signaux et des moyens pour adapter les paramètres de charge au signal reçu. In a variant (not shown) the battery device transmits a signal representing the charge parameters which are transmitted by the removable connection cable to the battery charger which therefore has an input for receiving these signals and means for adapting the charging parameters to the received signal.
