a lifting unit mounted on the first transfer block, and configured to move the lifting block up and down; and

a compression jig mounted on a front surface of the second transfer block facing the first transfer block, and configured to pressurize the battery when the first and second transfer blocks are transferred to be close to each other.

2 . The battery test device of claim 1 , further comprising:

a first fixing bracket coupled to the first pressure cylinder and fixed on the upper surface of the front portion of the base block; and

a second fixing bracket coupled to the second pressure cylinder and fixed to the upper surface of the rear portion of the base block,

wherein the first transfer block comprises a first vertical plate vertically erected between the first fixing bracket and the battery, and a pair of first side plates provided on left and right sides of the first vertical plate, and

the second transfer block comprises a second vertical plate vertically erected between the second fixing bracket and the battery, and a pair of second side plates provided on left and right sides of the second vertical plate.

3 . The battery test device of claim 2 , further comprising:

a first fireproof chamber installed in the base block to accommodate the first fixing bracket and the first pressure cylinder, and filled with carbon dioxide, and

a second fireproof chamber installed in the base block to accommodate the second fixing bracket and the second pressure cylinder, and filled with carbon dioxide.

4 . The battery test device of claim 2 , further comprising:

a first load cell on a portion of the first vertical plate to which pressure is applied by the first pressure cylinder, and

a second load cell provided on a portion of the second vertical plate to which pressure is applied by the second pressing cylinder.

5 . The battery test device of claim 4 , wherein the first and second pressure cylinders are applied as hydraulic cylinders for buffering an impact force applied in a direction in which a piston is inserted to conduct a battery collision test.

6 . The battery test device of claim 2 , further comprising a jig transfer cylinder configured to transfer the compression jig in a width direction of the base block.

7 . The battery test device of claim 2 , wherein the lifting unit comprises:

a lifting cylinder including a lifting piston to be drawn in a vertical direction, and coupled to a front surface of the first vertical plate; and

a lifting chain arranged to be hung on an idle roller on an upper end of the first vertical plate, and having both longitudinal ends coupled to the lifting piston and the lifting block.

8 . The battery test device of claim 2 , wherein the lifting block comprises a horizontal part on which the battery is placed, and a vertical part coupled to one end of the horizontal part while in contact with an outer side of the first vertical plate.

9 . The battery test device of claim 8 , further comprising a fixing unit which comprises:

a pair of clampers mounted on left and right sides of the first vertical plate; and

a plurality of fixing cylinders configured to transfer the pair of clampers in a thickness direction of the first vertical plate so as to pressurize the vertical part against the first vertical plate or separate the vertical part from the first vertical plate.

10 . The battery test device of claim 1 , further comprising:

a turntable provided on a portion of the lifting block on which the battery is placed, and configured to be rotatable about a vertical central axis; and

a rotating unit configured to rotate the turntable.

11 . The battery test device of claim 1 , further comprising:

a pair of fixing frames fixed on an upper side of the base block to be in parallel to the pair of guide bars in the longitudinal direction;

a transfer frame arranged perpendicular to the pair of fixing frames and configured to be moved in the longitudinal direction; and

a hoist mounted on the transfer frame to be transferred in a longitudinal direction of the transfer frame.

12 . The battery test device of claim 11 , further comprising a support, for a drop test, coupled to a point on an upper surface of the base block corresponding to a position of the hoist.

13 . The battery test device of claim 1 , wherein the compression jig is detachably coupled to the second transfer block, and

the battery test device further comprises a penetration jig mounted on a front surface of the second transfer block and including a through pin configured to pass through the battery when the first and second transfer blocks are transferred to be close to each other.

14 . The battery test device of claim 1 , further comprising a heating device configured to heat the battery, which is placed on the lifting block, to an ignition temperature.
