  • Publication number: 20230282893
    Abstract: A battery pack is proposed. The battery pack may include an electrode assembly and a protective circuit module including a circuit board having an intaglio electrically connected to a conductive pattern formed on a plate surface, and a tab connector electrically connected to a first electrode tab and a second electrode tab, respectively. The tab connector is electrically connected to the circuit board on the intaglio. When the electrode tabs and the tab connector are brought into contact with an anisotropic conductive film, conduction of conductive balls can be made at the intaglio of the tab connector. Therefore, even if the compressed surface is non-uniform, stable resistance and electrical connection can be provided by minimizing resistance distribution due to height imbalance of the anisotropic conductive film.
