In order to manage power exchanged between an electric vehicleand a house systemincluding an electric device, a power management device includes a vehicle detection portionconfigured to detect a vehicle available for a resident of the house. A controllerdetermines power supplied from the electric vehicleto the house systemin accordance with the presence of the vehicle detected by the vehicle detection portion. The power management device can thereby supply power from an electric vehicle to a house while securing the situation where the resident can move by vehicle in emergencies.

Power management device

A control apparatus includes: a target value obtaining unit obtaining a total target value of power to be discharged from storage batteries; an SOH obtaining unit obtain information on a state of health for each of the storage batteries; a charge control unit determining how the power of the total target value is divided among and discharged from each of the storage battery. The charge control unit (i) compares the state of health of a first storage battery and the state of health of a second storage battery, and, in the case where the state of health of the second storage battery is higher than the state of health of the first storage battery, (ii) discharges from the second storage battery second power lower than first power which is discharged from the first storage battery.

A positioning receiver in which the circuit configuration of the receiving system corresponding to a plurality of positioning systems can be simplified and the current consumption and circuit size of which can be reduced. A positioning receiver () comprises first low-pass filters () which limit outputs of a first signal mixer () and a second signal mixer () to a first bandwidth, and second low-pass filters () which are provided on the output side of the first low-pass filters () and limit the outputs of the first low-pass filters () to a second bandwidth narrower than the first bandwidth and sets the filter bandwidth of the first low-pass filters () greater than that of the second low-pass filters ().
