The present invention provides an apparatus and method for controlling the charging capacity of a battery to minimize battery damage, thereby enabling the battery to be used for a longer time. More specifically, the present invention provides a device and method for extending a battery life by reducing battery damage by controlling the charging capacity of the battery according to a temperature.

Method for controlling charge capacity of UPS battery

Disclosed is a packing structure for a lithium ion polymer battery, which includes: a battery casing including a lower multilayer polymer and an upper multilayer polymer, wherein the lower multilayer polymer has an inner space of a predetermined size for housing at least one electrode assembly and an electrolyte and is provided with an extension portion extending radially and outwardly from a top edge of each vertical portion of the lower multilayer polymer, a part of the upper multilayer polymer is coupled rotatably to a part of the extension portion of the lower multilayer polymer and remaining parts of the upper multilayer polymer are sealed to remaining parts of the extension portion of the lower multilayer polymer; and a battery protection member, which wraps the outer circumference of the battery casing so that the battery contained in the battery casing can be protected from external impact, and is fixed integrally by a part of the sealed extension portions. The packing structure can protect a battery from external impact while minimizing an increase in size of the whole battery.
