摘要： A diagnosis device and method for diagnosing whether a component included in a battery system fails, according to an embodiment of the present invention, monitor, on the basis of abnormal state data on the component, whether an abnormal state of the component occurs, measure a maintenance time of an abnormal state when the abnormal state occurs in the component, so as to compare the maintenance time and a preset reference time, check, on the basis of the maintenance time, whether preset early diagnosis conditions are satisfied if the maintenance time is less than the reference time, and determine, on the basis of whether the early diagnosis conditions are satisfied, whether the component fails, and thus provided are a high-performance, high-precision, high-efficiency and high-reliability diagnosis device and method, which diagnose early whether a failure has occurred so as to preemptively respond even to temporary abnormal state data that is less than the preset reference time.

摘要： A battery monitoring device monitors a lithium precipitation amount in a lithium ion battery. The battery monitoring device includes a precipitation amount detection unit (37) that has a short circuit (371) for discharging the lithium ion battery by temporarily shorting both ends of the lithium ion battery. The lithium precipitation amount detection unit calculates an estimation value of the lithium precipitation amount based on a change in at least one of current or voltage when both the ends of the lithium ion battery is shorted by the short circuit. The battery monitoring device includes a temperature sensor (31) that detects a battery temperature of the lithium ion battery. The precipitation amount detection unit calculates, as the lithium precipitation amount, a correction value obtained by correcting the estimation value with the battery temperature.

摘要： A method of predicting a capacity change of a battery includes calculating damage to cathode particles of a secondary battery during each charging/discharging cycle if the charging/discharging cycle is repeatedly performed in the secondary battery, calculating accumulated damage by accumulating the damage, calculating a minimum radius of the cathode particles in which a fatigue fracture occurs due to the accumulated damage, calculating, based on a distribution of radii of the cathode particles and the minimum radius, a reduction amount in a volume of a cathode active particle due to the fatigue fracture during each charging/discharging cycle, and calculating a relative capacity loss at a cathode based on the reduction amount in the volume of the cathode active particle during each charging/discharging cycle.
