An energy storage system of the present disclosure includes: a first battery module in which a plurality of battery cells are disposed; a second battery module in which a plurality of battery cells are disposed, and which is disposed to face the first battery module; a module screw which extends in a front-rear direction in which the first battery module and the second battery module are disposed, and fastens the first battery module and the second battery module; an upper fixing bracket which is disposed in an upper side of the first battery module and the second battery module, and fixes the first battery module and the second battery module; and a lower fixing bracket which is disposed in a lower side of the first battery module and the second battery module, and fixes the first battery module and the second battery module.

Energy storage system

A method of displaying items on a mobile terminal includes displaying a first icon group of a plurality of icons on a display of the mobile terminal, such that each icon of the first icon group is associated with an application that is executable on the mobile terminal. Also performed is detecting user contact at a first location of the display relative to a displayed location of a particular icon of the first icon group and detecting further user contact representing a dragging over a distance beginning from the first location, such that the dragging represents substantially continual user contact from the first location over the distance. Also, after the dragging occurs over a threshold distance, displaying a second group of icons in an icon display region, such that each icon of the second icon group is associated with an application that is executable on the mobile terminal.

Mobile terminal and method of controlling the operation of the mobile terminal

An energy storage system includes: a battery configured to at least store received electrical energy in a form of direct current, or output the stored electrical energy; a power conditioning system configured to convert an electrical characteristic to charge or discharge the battery; and a battery management system configured to monitor state information of the battery, wherein the battery includes a plurality of battery packs each including a respective plurality of battery cells, wherein the battery management system includes: battery pack circuit boards which are disposed in each of the plurality of battery packs, and configured to obtain state information of the plurality of battery cells included in each battery pack; and a main circuit board coupled to the battery pack circuit boards by a communication line, and configured to receive state information obtained by the battery pack circuit boards from each battery pack.

The present disclosure relates to a mobile terminal capable of providing optimal vibration power through sweeping of vibration frequencies, and a vibration power control method thereof. When a specific touch is detected after setting frequency sweep information in form of a table in a memory, at least one sweep frequency is swept at a preset period within a vibration frequency range exhibiting satisfactory vibration power using the frequency sweep information so as to drive a vibration motor, thereby maintaining vibration power always in an optimal state. Also, a driving voltage of the vibration motor may be dropped to reduce battery consumption while driving the vibration motor, and the sweep frequency range and the sweep period can be adaptively changed according to a type of application displayed on a screen to stably maintain vibration power irrespective of a change in an application.
