The invention provides a battery identification arrangement, a battery equipment suitable for identification and a battery identification method for implementation in an electronic equipment such as a mobile station or a charger with a battery. The present invention also relates to a method to measure the temperature of a battery connected to an electronic equipment. The battery identification arrangement includes both a measurement circuit of the electronic equipment and a battery circuit of a battery equipment. On identifying, means in the measurement circuit measure at least one identification voltage (Vid) which is generated by dividing a battery voltage (Vbat) into a division ratio by means of in series connected resistors (R1, R2) connected to ground. The resistors (R1, R2) are connected to the battery only during measurement of the identification voltage (Vid) and the battery voltage (Vbat).

L'invention concerne un dispositif d'identification de pile, un équipement (120) de pile convenant pour l'identification et un procédé d'identification de pile destiné à être mis en oeuvre dans un équipement (110) électronique tel qu'une station mobile ou un chargeur équipé d'une pile (13). La présente invention a également trait à un procédé permettant de mesurer la température d'une pile (13) connectée à un équipement (110) électronique. Le dispositif d'identification de pile comporte un circuit (1) de mesure de l'équipement (110) électronique et un circuit (14) de pile d'un équipement (120) de pile. Lors de l'identification, un dispositif situé dans le circuit (1) de mesure permet de mesurer au moins une tension (Vid) d'identification qui est produite par la division d'une tension (Vbat) de pile par un rapport de division au moyen de résistances (R1, R2) connectées en série et reliées à la terre (12). Les résistances (R1, R2) sont connectées à la pile (13) uniquement au cours de la mesure de la tension (Vid) d'identification et de la tension (Vbat) de pile.
