<P>PROBLEM TO BE SOLVED: To suppress a reduction in durability of a power storage device when the power storage device is charged with regenerated power of a motor as a power generation source of a deck crane. <P>SOLUTION: A power storage system 100 is mounted on a ship and has a plurality of deck cranes 1 in which at least one of a revolving device, an elevating device, a winch device is driven by the motor. The power storage system 100 includes: a plurality of power storage devices 52 for charging the regenerated power of the deck crane 1; a stored power amount detector 54 for detecting a stored power amount of the power storage devices 52; a power detector 53 for detecting the regenerated power of the deck crane 1; and a power storage controller 50 for selecting a power storage device 52 which is charged with the regenerated power of each of the deck cranes 1 and makes the power storage device charge based on the regenerated power detected by the power detector 53 and the stored power amount detected by the stored power amount detector 54. <P>COPYRIGHT: (C)2012,JPO&INPIT |
