Abstract: A congestion degree determination apparatus (2000) acquires a captured image (50) generated by an in-vehicle camera that captures an inside of a target vehicle. The congestion degree determination apparatus (2000) determines, for each of persons (30) present in the target vehicle, an area (20) in which the person (30) is positioned out of a plurality of areas (20) in the target vehicle using the captured image (50). The congestion degree determination apparatus (2000) determines the congestion degree of the target vehicle using the number of the persons (30) positioned in each of two or more of the areas (20).

Abstract: A battery management device to be mounted on an electric vehicle including a driving wheel, a traveling motor configured to generate a driving force for the driving wheel, and a battery configured to store electric power to be consumed by the traveling motor. The battery management device includes a detector configured to detect a state of the battery, and a controller configured to calculate a characteristic value indicating performance of the battery based on an output of the detector, and manage charging and discharging of the battery based on the characteristic value.
