Embodiment Construction

[0019] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The exemplary embodiments are described below to explain aspects of the present invention by referring to the figures.

[0020] As described herein, when a first element is expressed as being disposed on or formed "on" or "adjacent" to a second element, the first element may directly contact the second element or may be located between the first and second elements. One or more other elements between the two elements are separated from the second element. In contrast, when an element is referred to as being disposed or formed "directly on" another element, there are no intervening elements present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0021] Figure 1a is an exploded per...

Abstract

A battery pack including: a bare cell including a cathode and an anode; and a chip on board (COB) module (200) electrically coupled to the cathode and anode of the bare cell. The COB module controls the charging / discharging of the bare cell. The COB module can be commonly used in different types of batteries and can be connected to a variety of electric devices.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 2008-53204 filed with the Korean Intellectual Property Office (KIPO) on June 5, 2008, the disclosure of which is hereby incorporated by reference This article. technical field [0003] Aspects of this disclosure relate to battery packs. Background technique [0004] Generally, a battery pack is formed by electrically coupling bare cells to a protection circuit board. A bare cell includes an electrode assembly and an electrolyte sealed in a can. Bare cells charge or discharge according to reversible chemical reactions. The protection circuit board prevents the bare cell from overcharging and over-discharging by controlling the current of the bare cell. A battery pack may be mounted on an electronic device. [0005] The protective circuit board includes chip-type electrical components mounted on an insulating substrate by a surface m...
