Patent number: 9935298Abstract: Disclosed herein is a battery cell case. The battery cell case includes a front case plate and a rear case plate which are separably coupled to each other. The structures of the front and rear case plates are symmetrical structures, so that the battery cell case can be easily assembled in such a way that the front and rear case plates are coupled to each other with the battery cell disposed therebetween and are fastened to each other by holders fitted over the opposite ends of the case plates. In another embodiment, the structures of the front and rear case plates may be asymmetrical structures so that the front and rear case plates can be coupled with each other in an insert coupling manner without using a separate tool or fastening means.Type: GrantFiled: September 9, 2015Date of Patent: April 3, 2018Assignee: Global Battery Co., Ltd.Inventors: Gueng Hyun Nam, Seok Ho Kim, Min Ho Jang, Dae Ung Kim

Patent number: 9269931Abstract: In a battery cover, a sealed assembly structure of upper and lower covers of a battery case is configured in such a way that it forms a labyrinth structure that can allow an electrolyte to move upward and downward, thereby increasing an electrolyte leakage resistance of the battery case. Gas discharge holes and micro-holes are formed in the battery cover, and so the battery cover can easily discharge gas from the battery case. In the battery cover, electrolyte recovery ports are arrayed in such a way that the electrolyte can be prevented from leaking from the battery case even when the battery case is turned over or tilts to one side.Type: GrantFiled: February 8, 2013Date of Patent: February 23, 2016Assignee: GLOBAL BATTERY CO., LTD.Inventors: Hyun Ryung Kim, Seung Bok Park, Kyu Hyeong Lee

Patent number: 8785018Abstract: Disclosed herein is a battery pack case. An upper cover, a lower support base and each side cover form at least one seating depression extending in a sideways direction. Each of the front and rear covers has band locking depressions at positions corresponding to the seating depressions. Each band locking depression has a shape corresponding to a related one of fixing bands. Each fixing band includes a band body which is made of rubber, fabric or plastic and extends a predetermined length in one direction, and a locking protrusion provided on each of opposite ends of the band body. The locking protrusion has a structure corresponding to a related one of the band locking depressions. The locking protrusions of the fixing bands are inserted into the corresponding band locking depressions, thus fastening the elements including the front cover and the rear cover together.Type: GrantFiled: June 19, 2012Date of Patent: July 22, 2014Assignee: Global Battery Co., Ltd.Inventors: Gueng Hyun Nam, Tae Sin Kim, Duck Jun Lee, Jin Woo Roh, Min Ho Jang
