摘要： Controller performs a plurality of pieces of abnormality diagnosing processing in a vehicle. The plurality of pieces of abnormality diagnosing processing includes a first-type abnormality diagnosing processing of detecting the abnormality that occurs due to a plurality of types of causes and a second-type abnormality diagnosing processing of detecting the abnormality that occurs due to one type of the cause. When the abnormality is detected by the first-type abnormality diagnosing processing, controller specifies the cause of the abnormality detected by the first-type abnormality diagnosing processing based on a diagnosis result of the second-type abnormality diagnosing processing.

摘要： In failure estimating system for a battery module, failure estimating device includes: charge state calculating unit for calculating the charge state of battery module; ΔSOC calculating unit for calculating ΔSOC as the amount of variation of the charge state from the initial charge state of battery module; ΔV integrated value calculating unit for calculating ΔV as the difference between a maximum inter-terminal voltage value and a minimum inter-terminal voltage value among a plurality of battery blocks and calculating a ΔV integrated value by sequentially integrating the calculated ΔV; and number-of-failed-cells estimating unit for estimating, with reference to association file, the number of failed cells that corresponds to the calculated ΔSOC and ΔV integrated value. Association file is stored in storage unit, and associates the relationship between ΔSOC and ΔV integrated value with the number of failed cells.
