Abstract
A power supply control device controls charging and discharging of a power supply device including a plurality of power supply units which are connected in parallel to a load and a power generation unit. The power supply control device has relationship information indicating a relationship among a discharge current flowing from the power supply device to the load, a discharge current ratio that is a ratio of output currents of the plurality of power supply units, and a power loss of the power supply device, acquires a measured value of the discharge current, obtains, from the relationship information, the discharge current ratio at which the power loss of the power supply device corresponding to the acquired measured value of the discharge current is minimized, and adjusts the discharge current ratio so as to match with the discharge current ratio obtained from the relationship information.
