  • Patent number: 9515482
    Abstract: 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.
