An aspect of the present invention is a battery heating method for heating a battery in an electric vehicle when the temperature of the battery, which supplies power to an electric powertrain, is lower than a prescribed temperature determined in advance, or when it is estimated that the temperature of the battery will become lower than the prescribed temperature. This battery heating method has, as heating modes for heating the battery, a first mode for heating the battery by using heat generated by the battery itself, and a second mode for heating the battery by using heat generated by the electric powertrain. The first mode and the second mode are switched until the temperature of the battery reaches the prescribed temperature.
