Abstract: One or more embodiments relate to a battery pack including a heat dissipation structure. The battery pack according to one or more embodiments includes a case, an electrode assembly in the case, and including an electrode tab, a protection circuit module connected to the electrode tab, a fixing bracket at least partially surrounding the protection circuit module, and a heat dissipator outside the fixing bracket and including a heat dissipation element.

Abstract: A battery pack is disclosed. In one aspect, the battery pack includes a secondary battery including at least a pair of electrode tabs and a circuit board accommodating at least one circuit configured to control charging and/or discharging operations of the secondary battery. The circuit board includes a bending portion and first and second portions respectively extending from opposing ends of the bending portion and at least partially overlapping and spaced apart from each other. The first portion includes a tab fixing surface configured to fix the at least pair of electrode tabs thereto, and the second portion includes a circuit fixing surface configured to fix the at least one circuit thereto. The tab fixing surface faces the second portion. The battery pack also includes an insulating plate placed between the tab fixing surface and the second portion, and contacts the at least pair of electrode tabs.

Abstract: Provided is a battery pack including a switching member capable of smoothly sliding in a slide section while having a high fixing strength at an ON and/or OFF switching fixing terminal. In one embodiment, the battery pack includes a housing including a case and a cover coupled to the case, and a switching member inserted into the housing and including a sliding plate having a concave part formed on at least one of outer surfaces and a knob formed on an outer surface of the sliding plate, wherein the cover includes a first extension part extending to face an inner surface of the sliding plate and an interference part extending from the first extension part so as to make surface-contact with at least a portion of the outer surface of the sliding plate, and a hole through which the knob slides is formed on a sidewall of the case.
