Battery pack

摘要

A battery pack can stably fix a protection circuit module (PCM) to a battery cell while insulating the PCM. The battery pack includes a battery cell including an electrode assembly, and a case accommodating the electrode assembly and a terrace from which an electrode tab electrically connected to the electrode assembly protrudes, a PCM including a circuit board positioned on the terrace, and an electrode terminal formed on a top surface of the circuit board and connected to the electrode tab, a first insulation tape surrounding the PCM and allowing the PCM to be positioned on a top surface of the terrace, and a second insulation tape surrounding both side surfaces of the case, wherein the first insulation tape includes a body part surrounding the PCM and the terrace and a wing part protruding to both sides of the body part and fixing the body part to the case.

1. A battery pack comprising:
a battery cell that comprises:
an electrode assembly, anda case accommodating the electrode assembly and a terrace from which an electrode tab electrically connected to the electrode assembly protrudes; a protection circuit module that comprises:
a circuit board positioned on the terrace, andan electrode terminal formed on a top surface of the circuit board and connected to the electrode tab; a first insulation tape surrounding the protection circuit module and allowing the protection circuit module to be positioned on a top surface of the terrace; and a second insulation tape surrounding both side surfaces of the case, wherein the first insulation tape comprises a body part surrounding the protection circuit module and the terrace, and a wing part protruding to both sides of the body part and fixing the body part to the case, wherein the body part of the first insulation tape comprises:
a first region surrounding a bottom surface of the circuit board and a bottom surface of the terrace;a second region surrounding a top surface of the circuit board and a top surface of the terrace; anda bent region formed between the first region and the second region, wherein the wing part of the first insulation tape is formed on the first region and extends beyond the sides of the first region to cover the circuit board.
