ELECTRONIC APPARATUS COMPUTER DEVICE, INTELLIGENT BATTERY, METHOD OF COMPENSATING TOTAL CAPACITY, METHOD OF RECOGNIZING QUANTITY OF DETERIORATION, AND PROGRAM

PROBLEM TO BE SOLVED: To easily detect the degree of deterioration of a battery in an apparatus which is equipped with a battery for supplying power by charge and discharge. SOLUTION: This is a computer device which performs power supply to the system body from a mounted intelligent battery 52 for performing charge and discharge, and this intelligent battery 52 is equipped with a voltage measuring circuit 70 which measures its own battery voltage, a current measuring circuit 63 which measures its own charge and discharge currents, a temperature measuring circuit 90 which measures its own temperature, and a CPU 62 which periodically reads in the battery voltage measured by the voltage measuring circuit 70, the charge and discharge currents measured by the current measuring circuit 63, and the temperature measured by the temperature measuring circuit 90. The system body is equipped with an embedded controller 41 which receives the information about the deterioration of capacity from the CPU 62 of the battery.
