Abstract: To accurately detect abnormalities in parallel cell blocks that constitute a battery assembly.SOLUTION: A battery diagnostic device includes an SOC calculation unit, a ΔSOC acquisition unit, a maximum block identification unit, and a diagnostic unit. The SOC calculation unit obtains an SOC for each parallel cell block included in the battery assembly using an output of a battery sensor that detects the state of the battery assembly. The ΔSOC acquisition unit acquires, for each parallel cell block, a ΔSOC that indicates the degree of deviation between a first SOC at the start and a second SOC at the end when charging or discharging the battery assembly. The maximum block identification unit identifies the maximum block, which is the parallel cell block with the largest ΔSOC among diagnostic units set in the battery assembly. When the degree of deviation between the ΔSOC of the maximum block and a reference value of the ΔSOC exceeds a predetermined level, the diagnostic unit determines that an abnormality has occurred in the maximum block of the diagnostic unit.SELECTED DRAWING: Figure 9
