摘要： An apparatus for preventing battery overcharge is provided and includes a plurality of holders interposed between cells stacked within a battery to enclose the cells in a stacking direction. An installation space is formed between outer parts of at least two holders that enclose the cells. In addition, a fluid pouch is disposed within the installation space and adjacent to the cells inside the installation space, and contains a fluid therein. A cutting part is disposed within the installation space and has a first end disposed adjacent to the fluid pouch, and has a cutter edge heading between a lead tab and a bus bar at a second end of the cutting part.
