Claim:
1. A rechargeable battery protection apparatus comprising: a battery module comprising a plurality of unit cells coupled in series between a positive terminal and a negative terminal, and configured to be coupled to a charger through a first external port coupled to the positive terminal and through a second external port coupled to the negative terminal to charge the plurality of unit cells; a pack fuse on a high current path between the battery module and the charger; and a connector that forms a bypass path that bypasses a current between a first unit cell and a second unit cell among the plurality of unit cells to the pack fuse depending on an internal pressure of the battery module, wherein the connector comprises a first connector and a second connector, the first connector being between the positive terminal and the pack fuse, and the second connector being between the negative terminal and the pack fuse, and wherein the first connector is on the first unit cell and is configured to electrically couple the first unit cell and one end of the pack fuse depending on the internal pressure of the first unit cell, and the second connector is on the second unit cell and is configured to electrically couple the other end of the pack fuse and the second unit cell depending on the internal pressure of the second unit cell.
