Title:
CELL REPLACEMENT DETERMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/018888
Kind Code:
A1
Abstract:
A cell system is provided with n number of cell units composed of secondary cells. An index acquisition unit (51) acquires a degradation index for each cell unit. The degradation index corresponds to the state or characteristics of the cell units and depends on the degree of degradation of the cell units. A replacement necessity determination unit (52) selects a plurality of target cell units from among the n number of cells units and collectively determines the need to replace the plurality of target cell units, on the basis of the degradation indices (H[1]-H[n]) acquired for n number of cell units. In this case, the cell units estimated to have a relatively high degree of degradation are included in the plurality of target cell units on the basis of the degradation indices (H[1]-H[n]).
