Abstract:
1. A storage battery deterioration diagnosis system, comprising: a cell-list creator configured to select diagnosis target cells from among a plurality of cells in a storage battery system, and create a list of the diagnosis target cells; a cell deterioration diagnoser configured to obtain degradation degrees of the diagnosis target cells by performing deterioration diagnosis on the diagnosis target cells on the list, or by issuing a request of deterioration diagnosis of the diagnosis target cells to an external deterioration diagnosis device; a temperature distribution estimator configured to estimate degradation degrees of non-target cells being cells other than the diagnosis target cells, out of the plurality of cells, on basis of the degradation degrees of the diagnosis target cells and spatial distances between the non-target cells and the diagnosis target cells, and obtain temperature distribution of a whole of the plurality of cells based on the degradation degrees of the diagnosis target cells and the degradation degrees of the non-target cells; and a cell-list updater configured to select second diagnosis target cells densely from an area of a higher temperature and sparsely from an area of a lower temperature in the storage battery system on basis of the temperature distribution and create a second list of the second diagnosis target cells.
