Battery pack having pcm case

A battery pack configured to have a structure comprising a plate-shaped battery cell, which has an electrode assembly, configured to have a structure in which a separator is disposed between a cathode and an anode, received in a battery case together with an electrolyte in a sealed state and electrode terminals formed at one side thereof comprising a sealed surplus part, and a protection circuit module (PCM) mounted at the sealed surplus part, wherein

• each of the electrode terminals of the battery cell is made of a plate-shaped conductive member,
• the PCM comprises a protection circuit board (PCB), a safety element electrically connected between the electrode terminals formed at one side of the battery cell and the PCB or loaded on the PCB, and an electrically insulative module case for surrounding the PCB and the safety element,
• the module case comprises an upper case and a lower case coupled to each other through an assembly type fastening structure for receiving the PCB and the safety element,
• the module case, the PCB, and the electrode terminals are provided with first openings and second openings having a sufficient size to allow a first joint fastening member and a second joint fastening member to extend therethrough, and
• the PCB is loaded on the sealed surplus part of the battery cell in a state in which the PCB is received between the upper case and the lower case such that the PCB is electrically connected to the electrode terminals of the battery cell in a state in which the PCB is coupled to the electrode terminals of the battery cell by the first joint fastening member and the second joint fastening member.
