[0081] Like the first embodiment, the above-described second embodiment can suppress the deterioration of the secondary battery and prolong the service life of the secondary battery. In addition to the advantages described above, the second embodiment can save the user the trouble of having to explicitly input information about his / her schedule into the schedule DB 241 .

[0082] (Operation Procedure of Power Storage Device 20-2)

[0083] So far, refer to Figure 5 The configuration of the power storage device 20 - 2 according to the second embodiment has been described. In the next step, we will refer to Figure 7 The operation procedure of the power storage device 20-2 according to the second embodiment is described.

[0084] Such as Figure 7 As shown, first, in step S221 , the battery management unit 220 detects the remaining power of the secondary battery 210 and sends information about the remaining power to the charging control unit 250 .

[0085] Next, in step S22...

Abstract

The invention provides a power storage device, a power storage method, and a program, the power storage device including: a secondary battery; an acquisition unit that acquires charging period information for charging the secondary battery; and a charge control unit that calculates a charging power on the basis of the charging period information and controls charging power used for charging the secondary battery so that of the charging power is equal to the calculated charging power.

Description

technical field [0001] The present invention relates to a power storage device, a power storage method, and a program. Background technique [0002] In recent years, secondary batteries that can be used multiple times after repeated charging have been widely used as power sources for mobile terminal devices such as mobile phones and laptops. On the other hand, from global environmental protection and CO 2 From the viewpoint of emission reduction, power generation from renewable energy sources such as sunlight, wind power, geothermal energy and the like has attracted attention. Since the amount of energy obtained from these natural energy sources varies according to natural conditions such as the amount of sunlight and wind power, it is not easy to provide stable electric power using these natural energy sources. Therefore, efforts have been made to supply stable power by outputting stable power using a secondary battery in combination with natural energy. [0003] In addi...
