Abstract: A storage battery management device according to one embodiment includes a hardware processor that causes a display device to display first remaining life information and second remaining life information. The first remaining life information indicates current remaining life of a storage battery system.

The second remaining life information indicates remaining life of the storage battery system and corresponds to a case where one or more of the multiple storage battery modules are replaced with one or more other storage battery modules. The second remaining life information is calculated on the basis of an SOH of each storage battery module not being replaced and an SOH of each of the one or more other storage battery modules.

A first extremity (10) of the multilayer tube (1) is formed in such a manner that the thickness (H11) of the elastic layer (11) is thicker than the thickness (H12) of the hard layer (12).

Abstract: A storage battery management device includes an acquisition unit, a selection unit, an estimation unit, and a display control unit. The acquisition unit acquires a battery characteristic and an operation condition of a storage battery device. The selection unit selects data values from a data value group of a data item in which variation in data value is caused out of data items included in the battery characteristic and the acquired operation condition. The estimation unit estimates, for each of the selected data values, a battery characteristic after operation corresponding to a case where the storage battery device is operated under the operation condition. The battery characteristic is estimated on the basis of the battery characteristic and the operation condition acquired by the acquisition unit. The display control unit displays the battery characteristic estimated by the estimation unit in a comparable state.
