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.
