Title:
POWER SUPPLY CONTROL DEVICE AND POWER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2016059229
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To accurately estimate the remaining amount of a storage battery used in a power supply device, and to prolong the period of supplying power from the power supply device to an electric load relatively.SOLUTION: A power supply device 20 includes a solar panel 21, and a storage battery 23, i.e., a lead-acid storage battery. A power supply control device 10 includes a plurality of switches 33 provided, in one and one correspondence, between the power supply device 20 and an electric load 30. Furthermore, the power supply control device 10 includes a control unit 11 and a communication unit 14. The communication unit 14 communicates with the power supply device 20 and receives information about power generation state of the solar panel 21, and information about the battery voltage of the storage battery 23. The control unit 11 turns a specific switch 33 on during a period, when surplus power is generated from the solar panel 21 after the storage battery 23 has reached full charge, as a feeding period T1 for supplying power to the electric load 30.SELECTED DRAWING: Figure 1
