Abstract: In a battery abnormality detection system, a data acquirer acquires voltage data and current data of each cell of a battery pack having a plurality of cells connected in series or of each parallel cell block of a battery pack having serially connected parallel cell blocks having a plurality of cells connected in parallel. The abnormality detector detects a cell or parallel cell block in an abnormal state on the basis of a relative voltage change amount among the plurality of cells or among the plurality of parallel cell blocks in a constant voltage charging period.

Abstract: In a battery abnormality detection system, a data acquirer acquires a current flowing through a battery and a temperature of the battery. A determiner determines presence or absence of abnormal heat generation of the battery based on a relation between an amount of the current flowing through the battery in a certain period and a temperature rise of the battery in the certain period. The determiner determines the presence or absence of the abnormal heat generation of the battery based on the current and the temperature of the battery in a charging period in which the temperature of the battery exceeds a set temperature.

Abstract: A data acquirer acquires voltage data of each cell of a battery pack in which multiple cells are connected in series or voltage data of each parallel cell block of a battery pack in which parallel cell blocks, which each include multiple cells connected in parallel, are connected in series. A judgment unit judges, when a fluctuation in a voltage of each of two cells adjacent among the multiple cells or two parallel cell blocks adjacent among the multiple parallel cell blocks exceeds a threshold, that there is an abnormality in a voltage measurement system between a connection point of the two cells or the two parallel cell blocks and a voltage measurement unit.

Abstract: A data acquisition unit acquires temperature data for a plurality of battery packs mounted on different equipment (e.g., electric-powered vehicle) in a predetermined period. A statistical calculation unit calculates, for each battery pack, a statistical value based on a temperature change rate in a plurality of charging periods included in the predetermined period. A determination unit determines a temperature adjustment function of the equipment for which a deviation of the statistical value based on the temperature change rate is equal to or greater than a threshold value to be abnormal.
