ABNORMALITY FACTOR DETERMINATION APPARATUS, DEGRADATION DETERMINATION APPARATUS, COMPUTER PROGRAM, DEGRADATION DETERMINING METHOD, AND ABNORMALITY FACTOR DETERMINING METHOD

This abnormal factor determination device is provided with a measured value acquisition unit which acquires measured values including electric values and temperature values of multiple power storage elements, a predicted value acquisition unit which acquires predicted values including electric values and temperature values of multiple power storage elements, and a determination unit which, on the basis of the acquired measured values and predicted values, determines whether or not there are abnormal factors in the power storage system.
