1. A battery module, comprising:
a battery cell assembly including two or more longitudinal unit cells stacked in a thickness direction of a battery cell, wherein each of the two or more longitudinal unit cells comprises two or more battery cells having electrode leads provided at both ends thereof in a longitudinal direction and arranged in a row in the longitudinal direction;
a module case accommodating the battery cell assembly;
a sensing line electrically connected to the electrode leads of the two or more battery cells included in the battery cell assembly and sensing electrical properties of the battery cells, wherein the sensing line is accommodated in the module case and is having a first end exposed to an outside of the module case; and
a sensing plate coupled to the first end of the sensing line and sensing electrical properties of the battery module,
wherein the sensing line is connected to a terminal busbar coupled to at least one of the electrode leads of the battery cells included in the battery cell assembly, and the sensing line is electrically connected to the battery cells of the battery cell assembly through the terminal busbar,
wherein the terminal busbar is positioned between the electrode leads of the battery cells facing in the longitudinal direction of the longitudinal direction unit cell, and the electrode leads of the battery cells facing in the longitudinal direction are coupled to the terminal busbar,
wherein the terminal busbar comprises a first terminal busbar coupled to one electrode lead or electrode leads among the electrode leads of the battery cells facing each other in the longitudinal direction and a second terminal busbar that is coupled to the other electrode lead or electrode leads,
wherein the sensing line comprises a first sensing line coupled to the first terminal busbar and a second sensing line coupled to the second terminal busbar, and
wherein the sensing plate comprises a first sensing plate coupled to the first sensing line and the second sensing plate coupled to the second sensing line.
