    Abstract: Disclosed herein is a battery pack including (a) a battery cell array comprising two or more battery cells, each of which has an electrode assembly of a cathode/separator/anode structure disposed in a battery case together with an electrolyte in a sealed state, arranged in the lateral direction, (b) a protection circuit module (PCM) including connection terminals connected to electrode terminals of the battery cells by resistance welding, metal plates to electrically connect the battery cells to each other, and a protection circuit to control an operation of the battery pack, the PCM being connected to the upper end of the battery cell array, and (c) a pack case in which the battery cell array and the protection circuit module are disposed, wherein electrical connection regions between cathode terminals of the battery cells and the protection circuit module are configured to have a structure in which conductive plates attached to the tops of the respective connection terminals of the protection circuit module are welded so that the conductive plates surround the respective cathode terminals of the battery cells.

    Abstract: Disclosed herein is a pack case for battery packs in which a battery cell array including two or more battery cells arranged in a lateral direction and a protection circuit module (PCM) including a protection circuit to control an operation of the battery pack are mounted, the pack case including a lower case, on which the battery cell array and the protection circuit module are mounted, and an upper case disposed above the lower case so that the upper case covers the lower case to fix the battery cell array and the protection circuit module in place, wherein a lower case is partitioned into a battery cell mounting part, on which the battery cells are mounted, and a protection circuit module mounting part, on which the protection circuit module is mounted, a partition wall is formed at an interface between the battery cell mounting part and the protection circuit module mounting part, and openings, through which electrode terminals of the battery cells are exposed toward the protection circuit module, are formed at portions of the partition wall corresponding to electrical connection regions between the electrode terminals of the battery cells and the protection circuit module.
