REMAINING CAPACITY MEASUREMENT DEVICE OF SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a remaining capacity measurement device of a secondary battery simply calculating the remaining capacity independent of current flowing through the secondary battery. SOLUTION: The remaining capacity of the secondary battery is calculated from the measured thickness of the secondary battery by utilizing correlation of the thickness of the secondary battery with the remaining capacity. Concretely, a thickness detecting part 3 detecting the thickness of the secondary battery and a control part 4 calculating the remaining capacity of the secondary battery from the thickness are installed, and the remaining capacity of the secondary battery calculated with the control part 4 is displayed on a display part 5.
