Title
(EN) Secondary battery pack
Abstract
(EN)

Disclosed herein is a secondary battery pack including a battery cell having an anode terminal and a cathode terminal formed at one face having a sealed surplus portion and a protection circuit module (PCM) electrically connected to the battery cell via the anode terminal and the cathode terminal, wherein the PCM includes a board having a protection circuit formed thereon, the board being provided with an anode terminal connection part and a cathode terminal connection part connected to the anode terminal and the cathode terminal, respectively, a PCM case configured to receive the board through an open face thereof so that the PCM case surrounds the board, and an electrically insulative lid to close the open face of the PCM case.
