20130244084 | BATTERY PACK - A battery pack includes a region spaced a certain distance apart from a hole of a battery case. The region is different in surface roughness from the other regions of the battery case, and thus, a forming error of the hole may be visually detected, so as to decrease a condition setting time for controlling the forming error. | 09-19-2013 |
20150380715 | SECONDARY BATTERY - A secondary battery is disclosed. In one aspect, the battery includes a bare cell having a substantially prismatic shape, a first terminal located in a first region of a first surface of the bare cell and a second terminal located in a second region of the first surface of the bare cell. The battery also includes a first insulation tape located between the bare cell and the first terminal, wherein the first insulation tape covers the first surface of the bare cell, and second and third surfaces of the bare cell extending in a direction that crosses the first surface of the bare cell. The battery also includes a second insulation tape located between the first insulation tape and the first terminal. | 12-31-2015 |
20160087251 | BATTERY PACK - A battery pack includes a plurality of battery units. Each battery unit includes a can, an electrode assembly accommodated in the can and including a first electrode plate, a second electrode plate, and a separator between the first and second electrode plates, and a cap plate closing the can. The battery units are arranged side by side in a first direction. A protective circuit module is placed on the battery units and electrically connected to the battery units. An upper cover is placed on the protective circuit module; and a lower cover is positioned under the battery units and opposite the upper cover. The lower cover includes shock preventing portions protruding outward at both ends thereof. | 03-24-2016 |
