PROBLEM TO BE SOLVED: To provide a DC feed system that can more efficiently utilize power in storage batteries built in electric apparatuses.SOLUTION: The DC feed system includes: a controller configured to communicate with a plurality of electric apparatuses having power storage sections, and control power in the power storage section of each electric apparatus; and a DC bus for transmitting DC power to each electric apparatus. The DC feed system is configured to be connectable with a power supply device for supplying power to the DC bus. The controller includes an acquisition section for acquiring a battery level of the power storage section from each electric apparatus, and a control section for sending a control signal to control connection between the power storage section and the DC bus to each electric apparatus on the basis of the result of acquisition by the acquisition section. |
