BATTERY PACK HAVING IMPROVED STRENGTH

摘要

The present invention relates to a battery pack, comprising: a battery cell arrangement, in which two or more battery cells are arranged in a lateral direction, wherein each of battery cells is configured such that an electrode assembly having an anode/separation-film/cathode structure is sealed together with an electrolyte in a battery case; a protection circuit module (PCM) connected to the top of the battery cell arrangement so as to control the operation of the battery pack; a pack case, in which the battery cell arrangement and the protection circuit module are installed; and a plate-type reinforcing member interposed between the pack case and the battery cell arrangement so as to improve the mechanical strength of the pack case.
