Abstract
A battery system includes a battery module, thermistor, and ECU. The thermistor detects the temperature of a first area in the battery module. The ECU calculates the estimated temperature of a second area having a higher temperature than the first area in the battery module, by adding a temperature correction amount to a detected value of the thermistor. The ECU is configured to set the temperature correction amount according to a time differential value of the detected value. Then, the ECU sets the temperature correction amount such that the rate of increase of the estimated temperature of the second area does not exceed a predetermined rate that is larger than zero.
