Abstract

Disclosed is a battery pack that makes it possible to decrease a lead time of an insulating tape attaching process, and re-attach an insulating member. The battery pack includes a plurality of battery cells, a protection circuit module that controls charging and discharging of the battery cells, a first connecting plate electrically connecting the battery cells to each other, a second connecting plate electrically connected to the first connecting plate, and bent from the first connecting plate; and an insulating member disposed between the battery cell and the first and second connecting plates. The insulating member includes a first region placed between neighboring ones of the battery cells, and a plurality of second regions that are bent from the first region and are placed on outer surfaces of the neighboring battery cells, respectively.

Description

technical field [0001] Embodiments relate to a battery pack. Background technique [0002] Generally, a secondary battery is formed by putting an electrolyte and an electrode assembly into a case and sealing an opening of the case with a cap assembly including an electrode terminal. The electrode assembly includes a positive electrode plate, a negative electrode plate, and a separator as an insulator therebetween. [0003] Depending on the type of device employing the secondary battery, a unit cell (for example, a single bare cell) may be used as the secondary battery, or a single battery pack including a plurality of unit cells may be used. When a single battery pack including a plurality of unit cells is used, the unit cells may be connected to each other in series and / or in parallel through conductive plates. However, in some cases, if the conductive plate and the unit cells are moved out of physical contact with each other, the electrical connection between the conduct...
