Power generator, portable device, power generation scheme identifying system, and power generation scheme identifying method

摘要

Consciousness of environmental conservation is increasing nowadays, and there are power generators for a portable device and employing power generation schemes without a co2 discharge, such as solar power generation and hand-crank power generation. When, however, power is supplied, information indicating that the power is obtained from clean energy without a CO2 discharge is unknown at the portable-device side. When power is supplied from the power generator to the portable device, a power generation scheme identifier for identifying a power generation scheme is transmitted. The portable device identifies the power generation scheme identifier, and can recognize the power generation scheme of the connected power generator. A supplied power level is recognized based on a power level of the storage battery of the portable device at a time point of starting the power supply, and a power level of the storage battery at a time point of terminating the power supply. Since the power level in the storage battery is managed in this manner using the power generation scheme identifier, it becomes possible to determine whether or not the power generation scheme of the power in the storage battery is a clean scheme.

1. A portable device comprising:
a storage battery configured to store a plurality of types of power comprising a first type of power generated by using a clean energy and supplied from a power generator, and a second type of power generated by using another energy other than the clean energy; a power generation scheme identifier receiving unit configured to receive, from the power generator, a power generation scheme identifier for identifying a power generation scheme of the first type of power to be supplied; and a presenting unit configured to present the plurality of types of power and the power generation scheme identified by the power generation scheme identifier received by the power generation scheme identifier receiving unit such that each of the plurality of types of power and the power generation scheme are presented in association with each other, wherein the portable device is a mobile telephone, and wherein the presenting unit is configured to present to a user of the mobile telephone, a first ratio of a first amount of the first type of power remaining in the storage battery with respect to a total amount of the storage battery, and a second ratio of a second amount of the second type of power remaining in the storage battery with respect to the total amount of the storage battery.
