Abstract
In one embodiment, a temperature management device is provided with a plurality of battery cells, power sensor(s) each of which detects the charge/discharge power of battery cell(s) at a prescribed time interval, a power representative value calculation section which calculates a power representative value of a time lapse data of the charge/discharge power(s) detected by the power sensor, temperature sensor(s) each of which detects the temperature of battery cell(s) at a prescribed time interval, a temperature representative value calculation section which calculates a temperature representative value of a time lapse data of temperature(s) detected by the temperature sensor, a radiation characteristic identification section which identifies a radiation characteristic from the temperature representative value and the power representative value, and an air conditioning setting calculation section which calculates an air conditioning setting for the battery cell(s) corresponding to the power representative value by using the radiation characteristic.
