CONTROL DEVICE, POWER-FEEDING SYSTEM, CONTROL METHOD, AND PROGRAM

摘要

This power-feeding system (3000) includes a DC bus (3020), an electricity-generating device (3040) and a rechargeable battery (3060) connected to said DC bus (3020), and a measuring device (3100) that measures the voltage of the DC bus (3020). The electricity-generating device (3040) generates electricity and outputs a current to the DC bus (3020), and the DC bus (3020) outputs a current to a load (4000) and the rechargeable battery (3060). A first control unit (2020) gradually increases the magnitude of the current (charging current) inputted to the rechargeable battery (3060) from the DC bus (3020) until the voltage of the DC bus (3020) droops below the output voltage of the electricity-generating device (3040). A second control unit (2040) sets the magnitude of the charging current below the current magnitude at which voltage of the DC bus (3020) drooped.
