20100178552 | BATTERY CASE COVER - Provided is a battery case cover which can be produced through a single process, by integrally forming the structural components of a battery case cover such as a recovering part, a cell partition part and a gas inlet part on the bottom surface, while forming the recovering part in the shape of a pipe and applying a vent cap mode to the gas inlet part. | 07-15-2010 |
20120295136 | BATTERY PACK - A battery pack, including a casing receiving a battery module, the battery module comprising a plurality of batteries, a first cooling unit installed in a surface of the casing and introducing a coolant into the casing; and a second cooling unit installed in an opposite surface of the casing and discharging the coolant introduced into the casing by the first cooling unit to the outside of the casing, thus causing the coolant to flow in the casing, wherein the batteries of the battery module are laminated in a predetermined direction inside the casing, with a space defined between the batteries so that the coolant can pass through the space between the batteries; and an end of the space of the battery module is open toward the first cooling unit and an opposite end of the space is open toward the second cooling unit. | 11-22-2012 |
20130164575 | AUTOMOBILE BATTERY AND METHOD FOR MANUFACTURING POLE PLATES - A battery includes anode plates, formed as a mesh by forming cuts in series on a lead plate strip rolled into a uniform thickness, for storing electricity in a chemically reactive state by expansion processing, cathode plates formed as a mesh for storing electricity in a chemically reactive state, separators between the anode and cathode plates for electrical insulation, mechanical separation, and the impregnation of an AGM with electrolyte, such that the chemical reaction for storing electricity is facilitated and the pressure in the cell remains constant, upper and lower cases made of polypropylene and containing the anode plates, cathode plates, separators, and electrolyte in a plurality of mutually separate cells, and a cap coupled into the screw holes formed in the cell units in the upper case, for discharging gas generated during charge and discharge when the pressure of the gas is over a permissible level. | 06-27-2013 |
20130224523 | BATTERY CELL CASE - 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. | 08-29-2013 |
