Abstract: The present invention relates to a battery temperature adjusting system including: a battery unit having a heating pad; a leading wire connected to the battery unit; and a current induction unit surrounding the leading wire, wherein the current induction unit is electrically connected to the heating pad. The battery temperature adjusting system according to the present invention generates the induced current by applying the current induction unit surrounding the leading wire connected to the battery unit, and increases the temperature of the battery unit by supplying the induced current to the heating pad, thereby obtaining a desired battery output in a low-temperature region even without the use of an external power source.

Abstract: The present disclosure discloses an apparatus and method for sealing a pouch case that optimizes a sealing shape or structure of a sealing portion at an inner side of the pouch case to ensure insulation of a secondary battery. The apparatus for sealing a pouch case of a pouch-type secondary battery according to the present disclosure includes an upper compression jig to apply pressure to a sealing portion of the pouch case in a downward direction, and a lower compression jig to apply pressure to the sealing portion of the pouch case in an upward direction, and at least one of the upper compression jig and the lower compression jig applies the pressure to the pouch case at different depths at an inner side end and an outer side end.
