Abstract: The present technique relates to a battery device, a battery management method, and an electronic apparatus that can easily manage a battery device formed with a large number of battery cells. When a battery (51) has capacitive properties (or when the equivalent circuit of the battery (51) for an AC signal at a frequency f is a capacitor (51C)), a series circuit formed with a capacitor (171) and a coil (172) (=a coil (172-1)+a coil (172-2)) is provided in parallel to the battery (51), to form a blocking filter. The capacitor (171) and the coil (172-1) form a series resonance circuit. The capacitor (51C) and the coil (172-2) form a parallel resonance circuit.

Abstract: A control unit controls a reader/writer to generate a vehicle ID read signal that is formed of a high frequency signal and used to read a vehicle ID recorded in an ID circuit, and supply the signal to a high-pass filter. The read signal or a write signal formed of the high frequency signal is superimposed on a power supply line and supplied to the high-pass filter. The high-pass filter supplies the vehicle ID read signal formed of the high frequency signal to the ID circuit. On the basis of the read signal, the ID circuit reads the vehicle ID stored in an IC built in the own circuit and transmits it as a response signal to a charger along a reverse path. An authentication part of the control unit turns on a selector switch when the vehicle ID being the response signal is determined to be legitimate.

Abstract: The present technique relates to a power supply device and method as well as a program which can surely perform a billing process when a device is charged. When a vehicle ID registered in advance in an external storage matches a vehicle ID acquired by a reader/writer, a control unit makes a request to input, by operating a display unit formed of a touch panel, information which determines the amount of electric power to be charged. Once the information determining the amount of electric power to be charged has been input, the control unit controls a billing part to calculate the amount of electric power, so that a billing server performs a billing process on the amount of money corresponding to the amount of electric power. The control unit then controls a communication unit and turns on a selector switch.
