IPC: H04B1/40
Filed: 2001-12-24
Abstract: PURPOSE: A method for detecting and correcting an error of a maximum capacity data of a battery in a mobile communication terminal is provided to obtain accurate battery information by suitably correcting an error while tracking the maximum capacity data changing over use term of a battery. CONSTITUTION: The MC(maximum capacity) value stored in a memory of a battery is extracted for every predetermined period(S311) to discriminate whether the extracted MC value is within a pre-set MC availability range(S312). If the extracted MB value exceeds the MC availability range, an arbitrary value within the MC availability range is selected and set as the MC value(S313). If a battery is in a charging state(S314), an RC(Remaining Capacity) is measured for every predetermined period and compared with the stored MC value(S315,S316). If the RC value exceeds the MC value, it is judged that an error has occurred and an influx current capacity at the point is measured(S317). If the influx current capacity is greater than a pre-set threshold value, a greater value of the minimum value of the MC availability range and the RC is set as an MC value(S319). If the influx current capacity is smaller than the threshold value, an RC value at the point is set as an MC value(S320). The series of process is repeated performed for every certain period(S321).
