Abstract
Consciousness of environmental conservation is increasing nowadays, and there are power generators for a portable device and employing power generation schemes without a codischarge, 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 COdischarge 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.
