Abstract: The present technology relates to a detecting device and a detecting method that enable a state change of power lines to be detected with a simple circuit configuration. For example, when electronic devices 10A and 10B are connected to outlets 24-1 and 24-2 at the same time, a reader/writer 26 is notified of a device IDA and an outlet ID1 and a device IDB and an outlet ID2. In this case, a controller 27 controls a switch 91-1 and temporarily turns off power lines connecting the outlet 24-1 and the reader/writer 26 and then turns on the power lines immediately. Thereby, when the switch 91-1 is turned off, the reader/writer 26 is notified of only the device IDB and the outlet ID2. Therefore, the controller 27 can determine that the electronic device 10B is connected to the outlet 24-2. Then, the controller 27 can determine that the electronic device 10A is connected to the outlet 24-1. The present disclosure can be applied to indoor wiring of a table tap or power lines.

Abstract: 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.
