A power supply system includes a first energy storage, a second energy storage, a power transmission circuit, and circuitry. The first energy storage outputs first output power to an electric load. The second energy storage outputs second output power to the electric load. The circuitry is configured to control the power transmission circuit to supply power from the first energy storage or from both of the first energy storage and the second energy storage to the electric load based on a demand power such that a first change in the first output power in accordance with a change in the demand power is lower than a second change in the second output power in accordance with the change in the demand power or a third change in an input power of the second energy storage in accordance with the change in the demand power.
