Abstract: A controller switches between modes each having a different connection state of a DC power supply and the capacitor with respect to first and second output points by controlling switches. A generation unit generates a reference wave including at least one carrier wave. The modes are classified into a sustaining mode in which no current is caused to flow to the capacitor, a charging mode in which a current is caused to flow to the capacitor, and a discharging mode in which a current in a direction opposite to that in the charging mode is caused to flow to the capacitor. The controller switches between the sustaining mode and a charging or discharging mode according to the comparison result between a signal wave and the reference wave.

Abstract: A vehicle storage battery management device includes a charge level acquiring portion, a power capacity acquiring portion and, a power capacity deriving portion. The charge level acquiring portion acquires data of a charge level, which indicates a ratio of a capacity of a storage battery installed in an electric drive vehicle to a full charge capacity of the storage battery, from the electric drive vehicle. The power capacity acquiring portion acquires data of an amount of charging power supplied to the storage battery or data of an amount of discharging power discharged from the storage battery. The power capacity deriving portion derives a unit capacity of the storage battery based on the amount of charging power or the amount of discharging power, and a change in the charge level that occurs according to the amount of charging power or the amount of discharging power.

Abstract: A first voltmeter measures a voltage of a connector held by a holder of a vehicle power device. A second voltmeter measures a voltage of a second port of a power converter. when the connector is held by the holder. A controller detects presence or absence of a malfunction in a connector-side switch based on: measurement results of the voltmeters while controlling the connector-side switch so that electrical connection between the second port and the connector is broken; and measurement results of the voltmeters while controlling the connector-side switch so that the electrical connection is made.

Abstract: A splitter includes, in parallel between trunk terminals and branch terminals, a signal branching circuit that blocks distributed power and passes a PLC communication signal and a power branching circuit that blocks the communication signal and passes the distributed power. In the signal branching circuit, impedance viewed from the branch terminal side is matched with characteristic impedance of a power line and impedance viewed from the trunk terminal side is higher than impedance viewed from the branch terminal side, in the frequency band of the communication signal. In the power branching circuit, input/output impedance is set to be sufficiently higher than the impedance of the signal branching circuit viewed from the trunk terminal side, in the frequency band of the communication signal.
