Information processing device, information processing method, and information processing system

An information processing method comprising:

• a reception step of receiving, by a server, operation information on a power supply device from the power supply device that supplies power to an electric apparatus detachably connected thereto;
• a ranking step of ranking, by the server, a user of the power supply device based on the received operation information;
• and
• a setting step of setting, by the server, an incentive to the user based on a rank of the ranked user,
• wherein when the power supply device includes an engine generator, the operation information includes:
• fuel consumption information indicating a fuel consumption amount of the engine generator;
• and
• measurement information indicating measurement results of voltage and current that the power supply device is supplying to the electric apparatus, and
• wherein the ranking step includes identifying fuel consumption of the engine generator based on the fuel consumption information and the measurement information, and ranking the user based on the identified fuel consumption.

An information processing system comprising a plurality of power supply devices that supply power to electric apparatuses detachably connected thereto, and an information processing device capable of communicating with the power supply devices via a network,

• wherein the information processing device includes:
• a reception unit configured to receive operation information on the power supply devices from the respective power supply devices;
• a ranking unit configured to rank users of the power supply devices based on the received operation information;
• and
• a setting unit configured to set incentives to the users based on ranks of the ranked users,
• wherein when the power supply devices each include an engine generator, the operation information includes:
• fuel consumption information indicating a fuel consumption amount of the engine generator;
• and
• measurement information indicating measurement results of voltage and current that the relevant power supply device is supplying to the relevant electric apparatus, and
• wherein the ranking unit identifies fuel consumption of the engine generator based on the fuel consumption information and the measurement information, and ranks the users based on the identified fuel consumption.
