Document Type and Number:
Japanese Patent JP4089157
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply system which has a shelf life and improves the yield of the secondary battery. SOLUTION: A cell control circuit, which controls the secondary battery by each cell, is connected to each lithium ion secondary battery. The secondary battery whose voltage drop rate is large is connected to the cell control circuit whose dark current is small, and the secondary battery whose voltage drop rate is small is connected to the cell control circuit whose dark current is large. Dispersion can be made small by absorbing the voltage drop rate of each secondary battery using the voltage drop rate of the dark current of the control circuit.
