Abstract
A battery system includes a monitoring unit configured to detect voltages, currents, and temperatures of cells included in a battery. An ECU increments a count value when an SOC variation among the cells becomes larger than a threshold, based on the detection results of the monitoring unit. The ECU increments a count value when a positive electrode potential of the cell becomes lower than a threshold, based on the detection result of the monitoring unit. The ECU diagnoses that the battery is degraded when the amount of change in any of the count values becomes equal to or larger than a predetermined value.
