ELECTRICITY STORAGE MODULE, DETERIORATION DETERMINATION DEVICE OF THE SAME, AND DETERIORATION DETERMINATION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electricity storage module capable of performing deterioration determination at low cost, with ease, and without imposing a load on a CPU, and the deterioration determination method of the same.SOLUTION: An electricity storage module 1 includes a plurality of electricity storage cells (an electricity storage cell 10-1, an electricity storage cell 10-2, an electricity storage cell 10-n) and a determination section 20 for performing deterioration determination processing to determine the state of deterioration of the electricity storage cells based on a voltage difference among the electricity storage cells at a first measuring point in a first voltage region lower than the midpoint voltage of the electricity storage cell.SELECTED DRAWING: Figure 1
