Abstract:
A battery pack containing a CPU and allowing correction of measured data, wherein said CPU has at least:a main program for obtaining data concerning a voltage of each cell, charge/discharge current and temperature to control charging and discharging and to perform cumulative calculation of a remaining battery capacity; a communication program for communicating with an external device; and a correction program for acquiring measured data to obtain a correction factor for calculating a predetermined value from each item of said measured data and for storing said correction factor in a memory; wherein after a state of each cell has been set to a predetermined value, said correction program is started to obtain a correction factor and to store the correction factor in said memory, and said main program corrects each item of measured data concerning the voltage of each cell, charge/discharge current and temperature by the correction factor to control charging and discharging and to perform cumulative calculation of a remaining battery capacity.
