Battery protection circuit and battery pack including same

A battery pack, comprising:

• a battery cell;
• a first pack terminal and a second pack terminal;
• a charging switch connected in series between a first electrode of the battery cell and the first pack terminal;
• a first resistor to include a first end connected to a second electrode of the battery cell;
• a charging controller to supply a charging control current;
• a switching circuit to connect a second end of the first resistor with a control terminal of the charging switch or to block a connection between the second end of the first resistor and the control terminal of the charging switch depending on the charging control current;
• a fuse circuit, connected in series between the second electrode of the battery cell and the second pack terminal, to block a charging path depending on a voltage applied to a control terminal of the fuse circuit;
• and
• a fuse driving circuit to switch the voltage applied to the control terminal of the fuse circuit depending on a voltage between the first and second ends of the first resistor.

A battery protection circuit, comprising:

• a charging switch connected to a first electrode of a battery cell;
• a resistor connected between the charging switch and a second electrode of the battery cell;
• and
• a fuse circuit to block a charging path of the battery cell, the fuse circuit including a fuse and a heater, the heater to heat the fuse to block the charging path based on a voltage drop across the resistor which is indicative of a defect of the charging switch.
