The present technique relates to a communication device, a communication method, a battery device, and an electronic apparatus that can easily manage a battery device formed with a large number of battery cells. A transformer (171) is formed with a coil (181) on the side of a battery (51) and a coil (182) on the side of an IC chip (53). The number of turns in the coil (181) is small while the number of turns in the coil (182) is large. In a battery cell (31-3), the number of turns in the coil (181) of the transformer (171) is small (the resistance is low), and loss in an AC signal can be reduced accordingly. A voltage generating unit (151) having the large number of turns in the coil (182) can generate a high voltage, and supply the high voltage to the IC chip (53). The present invention can be applied to an electronic apparatus that includes a large number of battery cells, for example. |
