Abstract: 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.

Abstract: Current-integration estimation unit estimates the SOC of a battery by integrating the value of the current flowing through the battery. Open-circuit voltage estimation unit estimates the open-circuit voltage value of the battery from a value that includes at least the measured voltage value of the battery and indicates the state of the battery, and identifies the SOC corresponding to the open-circuit voltage value. In neither charged nor discharged state, SOC determination unit employs the SOC estimated by open-circuit voltage estimation unit. In charged or discharged state, SOC determination unit employs the SOC estimated by current-integration estimation unit without change or after correction using the SOC estimated by open-circuit voltage estimation unit. In parallel with the SOC estimation, SOH estimation unit estimates the SOH of the battery based on the variation value of the SOC employed by SOC determination unit and the integrated current value in the time period required for the variation.
