SECONDARY BATTERY PACK

摘要

A secondary batter pack disclosed in the present application comprises: a battery cell comprising a sealed surplus part, and having a cathode terminal and an anode terminal on one surface thereof; and a protection circuit module (PCM) connected electrically to the battery cell via the cathode terminal and the anode terminal. The PCM comprises: a substrate having a protection circuit formed thereon, and having a cathode terminal connecting part and an anode terminal connecting part, which connect to the cathode terminal and the anode terminal, located therein; a PCM case constructed so as to house and encase the substrate through one open side thereof; and an electrically insulating cover which seals the open side of the PCM case, wherein the substrate is connected to the cathode terminal and the anode terminal of the battery cell by the cathode terminal connecting part and the anode terminal connecting part, and the PCM case houses the substrate which lies parallel to the battery cell, and is mounted on the sealed surplus part of the battery cell after the open side thereof is sealed with the electrically insulating cover.
