    Abstract: An example may include a battery cell and a controller configured to control charging of the battery cell, using a charging switch. The controller may be configured to adjust a charging current supplied to the battery cell by controlling the charging switch to prevent a voltage of a load from being less than a reference voltage when a voltage of the battery cell is equal to or less than the reference voltage while power is being supplied to the battery pack and the load connected to the battery pack.
