Patent number: 10901046Abstract: An information processing apparatus (2000) detects a battery cell in which an abnormality (for example, leakage) occurs among a plurality of battery cells connected in series. A first differential voltage acquisition unit (2020) acquires a first differential voltage for each of the plurality of battery cells. The first differential voltage of the battery cell is a difference between a voltage of the battery cell after charging is completed and a voltage of the battery cell at a time when an operation is performed for a predetermined time after charging is completed. A determination unit (2040) determining that an abnormality occurs in a first battery cell, in a case where a difference between the first differential voltage of the first battery cell and the first differential voltage of a battery cell having a next largest first differential voltage of the first battery cell, is greater than or equal to a first predetermined value.Type: GrantFiled: June 7, 2017Date of Patent: January 26, 2021Assignee: Envision AESC Energy Devices, Ltd.Inventor: Mayuko Kishi
