POWER CONTROL DEVICE, STORAGE BATTERY SYSTEM, METHOD FOR CONTROLLING CHARGING POWER OF STORAGE BATTERY, AND PROGRAM

Abrégé

Provided is a power control device comprising: a storage battery connection unit equipped with an output power switching means capable of selecting a value of power to be output to a storage battery from among a plurality of different preset output power values; a power input unit for receiving power supplied from the outside; and a charging power control means for determining the value of power to be output to the storage battery. The charging power control means causes, at the time of execution of a charging power setting mode for determining the value of power to be output to the storage battery, the output power switching means to selectively change the output power value to a higher value, and determines a lower output power value than the selected output power value as being a value of power to be charged to the storage battery if the power output to the storage battery and load satisfies a predetermined first condition.
