A battery temperature control method and a battery temperature control device uses a controller to execute a temperature control of a chargeable/dischargeable battery installed in an electric vehicle. The controller acquires battery information including a temperature of the battery, a current temperature of the battery and a heat capacity of the battery, and predicts a scheduled time at which the temperature of the battery will be within a desired temperature range, or acquiring information pertaining to the scheduled time. The controller raises the temperature of the battery to the desired temperature range by the scheduled time by repeating a charge/discharge control of the battery as a heating control of the battery prior to the scheduled time where the temperature of the battery is below the desired temperature range.
