Abstract
The invention provides a battery identification arrangement, a battery equipment (120) suitable for identification and a battery identification method for implementation in an electronic equipment (110) such as a mobile station or a charger with a battery (13). The present invention also relates to a method to measure the temperature of a battery (13) connected to an electronic equipment (110). The battery identification arrangement includes both a measurement circuit (1) of the electronic equipment (110) and a battery circuit (14) of a battery equipment (120). On identifying, means in the measurement circuit (1) 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 (12). The resistors (R1, R2) are connected to the battery (13) only during measurement of the identification voltage (Vid) and the battery voltage (Vbat).
