APPARATUS AND METHOD FOR DETECTING FULLY CHARGED CONDITION, APPARATUS AND METHOD FOR DETECTING CHARGED CONDITION, AND APPARATUS AND METHOD FOR DETERMINING DEGREE OF DEGRADATION

摘要

It solves the problems, such as: fully charged state detection device is provided and its method is fully able to correctly detect the charged state of battery, even if working as the change of capacity fully charged state. ;It is electric motive power that a kind of ratio electricity of SOLUTION: CPU 23a detection charge efficiency, which accumulates in battery 13, the electricity of battery is flowed into, and starts charging in the arbitrary time and terminates to the charging 13 of battery based on identified charging current and charging voltage by using current sensor 15 and voltage sensor 17. The charged state 13 of full battery is detected, when the charge efficiency of detection is considered as zero. ;COPYRIGHT:(C) 2005, JPO& NCIPI
