The objective of the present invention is to provide a battery module including a voltage sensing module and the voltage sensing module detachable from a voltage module as well as stably and electrically connected to a bus bar attached on a battery cell. The voltage sensing module according to the present invention comprises: a bus bar assembly connected to the battery module; and a connector substrate detachably connected to the bus bar assembly. Additionally, the bus bar assembly comprises: a plurality of bus bars for connecting the connector substrate and the battery cell; and a combining member, connected to the battery module, for maintaining the bus bars at a certain location arrangement. The connector substrate includes an insertion hole. Also, the bus bar comprises: a connecting unit connected to a tap of the battery cell; an insertion unit inserted into the insertion hole of the connector substrate; and a middle unit covered by the combining member, and connecting the connecting unit and the insertion unit. |
