Battery management system

摘要

The present invention relates to a mobile terminal (1) for a wireless telecommunication system, with a main body (2) and a battery pack (3) to be connected to said main body (2). The main body (2) comprises a first frequency generating means (4) for generating a first frequency information and a processing means (5) for processing said first frequency information to provide a real time information. The battery pack (3) comprises a second frequency generating means (12) for generating a second frequency information and control means (11) for controlling the transmission of said second frequency information to said processing means (5). The processing means (5) uses the second frequency information for providing updated real time information, whereby the control means (11) comprises a battery pack memory (13) for storing first information relating to an update value of the second frequency information. The first information can thereby be a calibration value for calibrating the second frequency information or an indication value indicating that a calibration value for the second frequency information is stored in the main body (2). <IMAGE>
