Abstract: The present invention relates to a battery pack. The battery pack includes a plurality of battery cells arranged side-by-side, a lead plate electrically connecting the plurality of battery cells, a protection circuit module electrically connected with the plurality of battery cells, and a temperature sensor electrically connected with the protection circuit module to measure a temperature of the plurality of battery cells, wherein the lead plate has hole into which the temperature sensor is inserted, for fixing the position of the temperature sensor. By the above construction, the installation position of the temperature sensor is specified, so that the temperature sensor may be prevented from being damaged and the reliability of the temperature sensor may be enhanced.

Abstract: The battery pack includes a first case, a second case coupled with the first case, a plurality of battery cells which are received between the first case and the second case and are positioned side-by-side, and a label comprising a first surface attached to an outer surface of the first case and a second surface attached to an outer surface of the second case, in which a side coupling portion of the first case and the second case forms an outwardly convex round shape, the label comprises an intermediate surface which encloses an outer circumferential surface of the side coupling portion, and the intermediate surface is formed continuous from the first surface and the second surface. Thus, area and thickness of a label-attached portion of a case on which a label is attached may be minimized, allowing a slim structure of a battery pack.
