According to various embodiments of the present disclosure, one protection circuit module and a cell sensing structure for sensing voltages of each battery cell may be implemented. In FIG. 10A, the horizontal axis represents the charging time and the vertical axis represents the battery cell voltage. Referring to FIG. 10A, the cell sensing structure may be implemented such that the voltage sensor senses only the voltage of the battery cell through direct electrical connection between the voltage sensor and the battery cell. The electronic device to which the cell sensing structure is applied may sense the voltage of the battery cell without including the impedance of the protection circuit module when sensing the voltage of the battery cell during charging. Accordingly, since the initial charging constant current (CC) section 701 is relatively long and the constant voltage (CV) section 702 is short, the full charge (eg, 100% charging) time is reduced. For example, it can be seen that the filling time is approximately 89 minutes on the graph of FIG. 10A.

For example, it can be seen that the filling time is approximately 98 minutes on the graph of FIG. 10B.
