Some embodiments of this application relate to the field of battery manufacturing technologies and particularly disclose a battery pack. The battery pack includes: a cover plate, a cell module, a first resin layer, a battery pack housing, and at least one first monitoring member. The cell module is accommodated inside the battery pack housing and fastened by the first resin layer, the cover plate is fastened to the battery pack housing, and the cell module includes a plurality of cells stacked in a first direction. Each cell includes an electrode assembly, a cell housing configured to accommodate the electrode assembly, and a tab electrically connected to the electrode assembly. The cell housing includes a sealing portion, and the tab extends out of the cell housing from the sealing portion in a second direction. One of the at least one first monitoring member is disposed between sealing portions of the adjacent cells. The first monitoring member is connected to the cell module, and the first monitoring member is configured to monitor temperature of the tab of the cell. In this way, a risk of thermal run away of a battery pack during charging and discharging can be reduced in some embodiments of this application.
