1. A battery module array, comprising:

  • a plurality of battery modules, each having two secondary battery cells, a module frame and a cooling fin, each battery module having a first electrode lead extending from a front of the battery module and a second electrode lead extending from a rear of the battery module;

    end plates provided at both sides of a battery module assembly configured by assembling the plurality of battery modules;

    a ‘

    [’

    -shaped tension bar coming in contact with a top end of the battery module assembly and fixed to the end plates;

    a U-shaped sensing line assembly having a central portion, a first side and a second side and a first plurality of connectors connected to and extending from the first side to electrically connect to the first electrode leads of the battery modules and a second plurality of the connectors connected to and extending from the second side to electrically connect to the second electrode leads of the battery modules;

    a terminal bus bar configured to electrically connect the electrode leads of the battery modules included in the battery module assembly to each other;

    a front cover configured to cover an entire front surface of the battery module assembly; and

    a rear cover configured to cover an entire rear surface of the battery module assembly,wherein the front cover and rear cover extend between the end plates,wherein the central portion of the sensing line assembly extends over an outside surface of one of the end plates and between the front cover and rear cover,wherein the plurality of battery modules are stacked in a first direction extending between the end plates,wherein the first side of the sensing line assembly extends from the central portion in the first direction and directly contacts electrode leads of the front surface of the battery module assembly, the first side of the sensing line assembly being between the battery module assembly and the front cover, andwherein the second side of the sensing line assembly extends from the central portion in the first direction and directly contacts electrode leads of the rear surface of the battery module assembly, the second side of the sensing line assembly being between the battery module assembly and the rear cover.
