    Abstract: The present disclosure relates to a charge power control apparatus, a charge power control method, a program, and a solar power generation system, for improving charge efficiency. A solar power generation system includes a solar panel that receives sunlight to generate power, a PV power conditioner that performs DC/AC conversion of the power generated by the solar panel, and a charging AC/DC converter that performs AC/DC conversion of power output from the PV power conditioner and charges a storage battery. Voltage of the power supplied to the PV power conditioner from the solar panel is acquired while the power supplied from a power system is stopped, and a change in power supplied to the PV power conditioner from the solar panel is obtained according to the voltage. Charge power that is output from the charging AC/DC converter to charge the storage battery is adjusted based on the change in voltage.

    Abstract: A rechargeable battery controller is combined with a rechargeable battery and used in an existing PV system. The controller includes a DC-DC converter, which allows power to be passed between a power line and a rechargeable battery, and a control unit, which determines whether maximum power point tracking (MPPT) control using hill climbing is being performed by a PCS based on an input voltage or current value of the PCS. The control unit regulates charge/discharge power of the rechargeable battery to allow input power of the PCS to be a target value based on the input voltage and current values of the PCS while MPPT control using hill climbing is performed, and maintains, in a period during which MPPT control using hill climbing is not performed, the charge/discharge power to be the power at a beginning of the period.

    Abstract: The present disclosure relates to a charging control device, a solar power generation system and a charging control method which allow more efficient charging. The charging control device includes: a charging converter which takes electric power out of a solar panel and converts the electric power to a voltage required for charging a storage battery; and a controlling CPU which adjusts an output voltage that is outputted from the charging converter. The charging converter takes electric power out of the solar panel at two operation points where the electric power can be taken out of the solar panel with a certain output voltage, and charges the storage battery. The controlling CPU adjusts the output voltage in accordance with a voltage difference between input voltages respectively corresponding to the two operation points. The present technique is applicable, for example, to the charging control device of the solar power generation system.

    Abstract: A power line interface is electrically connectable to a direct-current power system including a power line. A bidirectional DC-DC converter is electrically connected to the power line interface and a battery. A controller receives a first current value measured by a first current sensor and a current command value and performs constant current control processing that controls the bidirectional DC-DC converter so that the first current value equals the current command value. The controller receives a first voltage value measured by a voltage sensor and a voltage command value and performs constant voltage control processing that controls the bidirectional DC-DC converter so that the first voltage value equals the voltage command value. The controller switches operation from the constant current control processing to the constant voltage control processing.
