1 . An apparatus for charging and discharging a secondary battery, the apparatus comprising:
a support housing module configured to support constituent elements of the apparatus for charging and discharging a secondary battery,
wherein the support housing module comprises:
a first support frame;
a second support frame spaced a predetermined distance apart by a support shaft from the first support frame and paired with the first support frame;
a screw support bracket fixed to the support shaft by being supported thereon and provided between the first support frame and the second support frame;
a first moving screw, one end portion thereof being combined with the first support frame and another end portion thereof being combined with the screw support bracket;
a second moving screw, one end portion thereof being combined with the second support frame and another end portion thereof being combined with the screw support bracket;
a first pressing assembly being moved along a lengthwise direction of the first moving screw as the first moving screw is rotated; and
a second pressing assembly being moved along a lengthwise direction of the second moving screw as the second moving screw is rotated, and
wherein pressure sensor units are provided on the first pressing assembly in such a manner as to be symmetrical about an imaginary vertical line passing the center of the first pressing assembly.
2 . The apparatus of claim 1 , wherein the first pressing assembly comprises:
a first moving plate, a first screw nut to be combined with the first moving screw being provided on both sides of the first moving plate;
a first push plate providing a pressing plate pressing against a battery cell with pressure for pressing that is transferred from the first moving plate, a support shaft being inserted into both sides of the first push plate for passing-through; and
a pressure sensor unit provided between the first moving plate and the first push plate and measuring the pressure for pressing that is applied to the battery cell.
3 . The apparatus of claim 2 , further comprising:
a separation prevention pin combined with the first moving plate and the first push plate and preventing separation of the pressure sensor unit,
wherein the separation prevention pin comprises:
a head portion supported on a stepped jaw groove formed in the first moving plate; and
an extension portion extending from the head portion and fixed to the first push plate.
4 . The apparatus of claim 2 , wherein one side of the pressure sensor unit is inserted into a first sensor support groove formed in the first moving plate, and the other side of the pressure sensor unit is inserted into a second sensor support groove formed in the first push plate.
5 . The apparatus of claim 2 , wherein a pressure-for-pressing transfer member that protrudes from one surface of the first push plate and presses against the pressing plate is provided between first through-holes into which plate moving shafts, respectively, formed on both sides of the first push plate, are inserted for passing-through.
6 . The apparatus of claim 1 , wherein the first pressing assembly and the first moving screw are combined with each other in a manner that forms a TM screw, and the second pressing assembly and the second moving screw are combined with each other in a manner that forms a ball screw.
7 . The apparatus of claim 1 , further comprising:
a plurality of cell pressing modules provided on the support housing module,
wherein each of the plurality of cell pressing modules comprises:
a pressing plate pressing against a battery cell; and
a heating pad combined with one surface of the pressing plate and heating the pressing plate, and
wherein the pressing plate and the heating pad are configured in such a manner that combination surfaces thereof correspond to each other.
8 . The apparatus of claim 7 , wherein the heating pad is an epoxy plate in which a heat line is provided.
9 . The apparatus of claim 7 , wherein the heating pad is heated to a temperature of 130° C. or below.
10 . The apparatus of claim 7 , further comprising:
a protective pad covering the pressing plate and the heating pad,
wherein a cover insertion space into which the pressing plate and the heating pad are inserted is formed in the protective pad.
11 . The apparatus of claim 10 , wherein the protective pad is formed of a silicone material.
12 . The apparatus of claim 7 , wherein a combination-position protrusion portion is provided on the combination surface of the pressing plate with which the heating pad is combined, in such a manner as to protrude from the combination surface of the pressing plate,
wherein a combination-guide fixation jaw corresponding to the combination-position protrusion portion is configured to be provided on an edge portion of the heating pad, and
wherein a distance over which the combination-position protrusion portion protrudes is the same as a thickness of the heating pad.
