The present invention relates to a sensing assembly for a secondary battery module, a substrate holder in the sensing assembly, and a secondary battery module having the sensing assembly. The sensing assembly is connected to a cell tab of a battery cell while being mounted in a secondary battery module including a plurality of battery cells. The sensing assembly includes a substrate holder, which is an insulation material having a plate shape and fixed to the side of the cell tab; a plurality of voltage detection connection members, which are fixed to the substrate holder through insert-molding and have a tab connector extending to the cell tab and fixed to the cell tab and a substrate connector disposed at the upper side of the substrate holder; and a sensing PCB detachably coupled with a top portion of the substrate holder and making contact with the substrate connector while being positioned on the top portion of the substrate holder to receive a voltage of the cell tab. Since the sensing assembly for a secondary battery module and a secondary battery module including the sensing assembly according to the present invention have a structure where a sensing PCB is connected to a substrate holder through elastic contact only, assembly and separation of the sensing PCB to and from the substrate holder are simple and thus maintenance and repair can be easily performed. |
