20090317703 | BATTERY PACK - A battery pack is disclosed. The battery pack includes at least two battery cells to provide a high capacity battery pack. The battery pack includes a single PCM assembly controlling at least two battery cells to decrease inferiority due to overcharge and overdischarge. Since a connector tab electrically connecting at least two battery cells to a single PCM assembly is provided, contacts are not separated during the swelling of the battery cells to prevent contact inferiority. A top case and a bottom case are provided to be coupled with at least two battery cells to maintain a secure coupling between the at least two battery cells. | 12-24-2009 |
20100092859 | POLYMER BATTERY PACK AND METHOD FOR MANUFACTURING THE SAME - Disclosed are a polymer battery pack and a method for manufacturing the same. In the polymer battery pack, a bare cell and a protection circuit member are separated from each other by a holder frame such that the bare cell is coupled to the inner side of the holder frame and the protection circuit member is coupled to the outer side of the holder frame. The method for manufacturing the polymer battery pack includes: coupling a bare cell to the inner side of a holder frame; electrically connecting the bare cell to a protection circuit member; coupling the protection circuit module to the holder frame; coupling a cover to the holder frame; attaching an external label to the cover; attaching a water sensitive paper to the cover; and performing a function test for the battery. | 04-15-2010 |
20100209761 | CARD BATTERY AND CARD BATTERY CONNECTOR - A card battery to charge and/or discharge an external electronic apparatus, the card battery including: a card battery body including a bare cell and a first substrate electrically connected to the bare cell; and a connector including a protection circuit module electrically connected to the card battery body. | 08-19-2010 |
20110039134 | HEAT TRANSFER MEMBER FOR BATTERY PACK - A battery pack includes a battery cell including a cell tab, a protective circuit board including an internal terminal coupled to the cell tab and a positive temperature coefficient (PTC) device connected to the internal terminal, and a heat transfer member contacting the cell tab. The heat transfer member may be attached to the cell tab as well as the PTC device. Heat generated in the battery cell, the cell tab, and the internal terminal is quickly transferred to the PTC device through the heat transfer member to quickly interrupt current flow when the battery cell is exposed to high temperature. Therefore, the battery pack may have the improved stability and reliability. | 02-17-2011 |
20110052941 | SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME - A secondary battery secondary battery includes a bare cell having an electrode terminal, and a protective circuit module having a circuit board and a lead plate. The protective circuit module is electrically connected to the bare cell such that the electrode terminal and the circuit board are connected to each other through the lead plate. The lead plate includes a first plate mounted on the circuit board, and a second plate foldably connected to the first plate. | 03-03-2011 |

20090087693 | Secondary battery - A secondary battery having a porous filling member that occupies a portion of a molding space between a bare cell and a protective circuit board. The presence of the filling member makes it possible to uniformly apply a molding resin into the molding space and to reduce defects due to thickness irregularity of a mold or a surface defect thereof. The secondary battery includes a bare cell, a protective circuit module including a protective circuit arranged on a protective circuit board and a plurality of electrical connection members electrically connecting the protective circuit board to the bare cell, a filling member arranged between the bare cell and the protective circuit board and a mold covering the electrical connection members and the filling member | 04-02-2009 |
20100098974 | Protective circuit module and rechargeable battery including the same - A protective circuit module and a rechargeable battery including the same, the protective circuit module including a circuit board main body having an electrode terminal tab configured to electrically connect to an electrode terminal of a bare cell, a chip-type PTC device on the circuit board main body, and a heat transfer member connected to the chip-type PTC device and the electrode terminal tab. | 04-22-2010 |
20100143753 | BATTERY PACK - A battery pack includes a bare cell; a circuit module on the bare cell and electrically connected to the bare cell; a loop antenna attached to the bare cell and electrically connected to the circuit module; and a PTC device on the loop antenna and electrically connected to the circuit module. | 06-10-2010 |
20100143785 | Battery pack - A battery pack is constructed with at least two battery cells that are arranged in parallel to each other and provided with surfaces facing each other, and a spacer structure interposed between the facing surfaces of the battery cells. A through-hole is formed in an interior portion of the spacer structure and corresponds to a portion where thicknesses of the battery cells are increased when the battery cells are swollen. Therefore, the facing battery cells do not interfere with each other even if the thickness of the battery cell is changed due to swelling of the middle portion thereof when the battery cells are repeatedly charged/discharged in the case where at least two battery cells are included. | 06-10-2010 |
