Abstract: A battery module includes a battery cell stack constituted by stacked pouch-shaped battery cells, a busbar coupled to an electrode lead of each of the pouch-shaped battery cells, a housing configured to fix a position of the busbar, and a sensing unit coupled to the housing. The sensing unit is attached to a first surface of the housing that faces the battery cell stack and to a second surface of the housing, the second surface being an outer surface opposite to the first surface.

Abstract: The present invention includes: a main body which defines a storage space in the lengthwise direction, and in which a plurality of biosensors can be stacked; a cover member covering one end of the storage space and including a discharge hole through which only one biosensor located at the outermost edge of the stacked biosensors can pass; and a cover coupled to the cover member in order to be raised and lowered so as to open and close the discharge hole. The discharge hole is closed such that the biosensors stacked in the storage space are not contaminated and the infiltration of impurities into the storage space is prevented, and the discharge hole is temporarily opened when the biosensors are to be used in order to withdraw the biosensors.
