In a battery abnormality prediction system, an acquisition unit acquires a current flowing through a battery and a temperature of the battery. A prediction unit predicts the occurrence of an abnormality in the battery, based on a relationship between the amount of the current flowing through the battery for a certain period of time and a rise in the temperature of the battery for the certain period of time. The prediction unit may compare the ratio of an integrated amount of current to the temperature rise for the certain period of time with a threshold determined based on data on the battery having caught fire and thereby predict a sign of fire to be caught by the battery.
