Battery abnormality detection system, battery abnormality detection method, and non-transitory computer-readable recording medium

A battery abnormality detection method comprising:

• a step of acquiring a current flowing through a battery and a temperature of the battery;
• and
• a step of determining 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, wherein
• the determining step 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.

A non-transitory computer-readable recording medium having embodied thereon a battery abnormality detection program for causing a computer to execute:

• processing of acquiring a current flowing through a battery and a temperature of the battery;
• and
• processing of determining 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, wherein
• the determining processing 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.
