Abstract
An electronic equipment power charging system has a temperature difference producing device for converting external electrical energy to heat. The temperature difference producing device has heat sources for outputting heat having different temperatures to produce a temperature difference. An electronic equipment has an electrothermal power generator for generating electrical power using the temperature difference produced by the temperature difference producing device to drive the electronic equipment. A measurement device measures the temperatures of the heat outputted by the heat sources of the temperature difference producing device. A control device controls the temperatures of the heat outputted by the heat sources of the temperature difference producing device in accordance with the temperatures measured by the measurement device.
