Document Type and Number:
WIPO Patent Application WO/2014/010025
Kind Code:
A1
Abstract:
The present invention is provided with: a power source (100); a load (111) that is connected to the power source (100) and consumes electrical power; a power consumption measurement unit (122) that measures the power consumption of the load (111); a recording unit (125) at which the permitted power value that the load (111) can consume within the range of power supply from the power source (100) is recorded; a surplus power calculation unit (126) that calculates the difference between the permitted power value recorded at the recording unit (125) and the power consumption value measured by the power consumption measurement unit (122) as a surplus power value; and a conversion unit (135) that charges an electricity storage unit (140) by supplying from the power source (100) a power corresponding to the surplus power value. By means of the abovementioned configuration, the surplus power of the power source (100) is utilized to the greatest extent, and short-time charging and rapid charging of the electricity storage unit (140) are possible at a low cost.
