The present invention relates to a battery module and an electronic device. According to an embodiment of the present invention, the battery module comprises a first battery, a second battery, a correction device unit, and a battery controller. The first cell includes a first internal resistance and provides a first current. The second cell is connected to the first cell in parallel, includes a second internal resistance, and provides a second current. The correction device unit is connected to the first battery or the second battery. The correction device unit includes a variable resistor or a current source. The battery controller controls the correction device unit such that the first current and the second current are the same based on a difference in resistance values between the first internal resistance and the second internal resistance. According to the present invention, the battery module and the electronic device are configured to prevent performance deterioration of the first ...
