When detecting an abnormality, an in-vehicle wireless instrument in a plug-in vehicle sends an abnormality occurrence notification to a mobile terminal via an information center. The mobile terminal performs a notification to notify a user of the abnormality having occurred in the plug-in vehicle. When the user performs a charging forbiddance manipulation based on the notification, the mobile terminal sends a charging forbidding command to a power management ECU in the vehicle via the information center and the in-vehicle wireless instrument. When receiving the charging forbidding command, the power management ECU stops charging a battery using an external power source, and sends a setting completion notification to the mobile terminal via the in-vehicle wireless instrument and the information center. When receiving the setting completion notification, the mobile terminal notifies the user that the charging is stopped.

Charging control apparatus for an electricity storage apparatus in a vehicle

With a capacitor C inserted in an interstage portion of multiple stages of amplifier circuits, a high pass filter is generated by the capacitor C and an input impedance |Z| of an amplifier circuit in the next stage. Accordingly, frequency components lower than a cutoff frequency fc are cut off, and therefore are not transferred to the subsequent stage. However, radio frequency components higher than or equal to a fundamental wave component determined by an envelope of a radio frequency signal intermittently transmitted can be transferred. Consequently, transfer of DC offset potentials can be cut off, and noise, such as flicker noise, having great power in a DC or near-DC zone can be effectively cut off. Thereby, the S/N ratio, detection sensitivity, and detection accuracy can be improved.

Activation signal output circuit having multiple amplifier circuits

A start signal output circuit having an RF/DC conversion circuit to which radio frequency power (RF) of specified frequency is inputted and from which a direct current potential (DC) is outputted, comprises a detection/amplification circuitwhich includes a voltage doubler wave-detector circuitconfigured including a sensing diode Q(Tr) for sensing the RF power, a differential amplifier including differential pair transistors Trand Tr, and a current mirror circuit. A base current of one Trof the differential pair transistors is brought into substantial agreement with a DC component of a current flowing through the sensing diode Q(Tr). A total of currents flowing through the differential pair transistors Trand Tris regulated to a substantially constant value by the current mirror circuit. Thus, the start signal output circuit which is small in size, high in sensitivity and low in power consumption can be realized.
