Description

[0001] The present invention relates to an integrated cartridge and a battery pack having the same,

The present invention relates to a battery pack, and more particularly, to a battery pack incorporating the functions and structures of some components.

2. Description of the Related Art In recent years, secondary batteries have been widely used not only in small-sized devices such as portable electronic devices, but also in electric vehicles that require driving power by using internal combustion engines and / or electric motors. The electric vehicle includes a hybrid electric vehicle, a plug-in hybrid electric vehicle, a pure electric car driven only by an electric motor and a battery without an internal combustion engine, and the like.

In the case of an electric vehicle, a large number of secondary batteries are electrically connected to increase capacity and output. Particularly, pouch-type secondary batteries are widely used because they are easy to be stacked in a middle- or large-sized apparatus.

Since the pouch-type secondary battery is generally packaged in a battery case of a laminate sheet of aluminum and polymer resin, mechanical stiffness is not large. Therefore, when constructing a battery module including a plurality of pouch type secondary batteries, A cartridge is often used in order to prevent the flow and to facilitate stacking.

The plurality of cartridges accommodating the pouch type secondary battery are stacked one on the other, and the battery module may be composed of a plurality of stacked secondary cells and cartridges.

Meanwhile, the conventional cartridge is composed of a lower frame and an upper frame, for example, two secondary battery cells are stacked on an upper surface of a lower frame, an upper frame is laid on the upper frame, and an upper frame and a lower frame are coupled. The unit cartridges constructed in this manner are stacked one above the other to form the cell cartridge assembly. When the cell cartridge assembly is prepared, one battery pack may be completed by assembling the sensing assembly for sensing the voltage characteristics of the secondary battery and other electrical parts including the BMS, which are electrically connected to the plurality of secondary batteries.

However, in the conventional case, one of the unit cartridges must be assembled with another cartridge, and the assembled and stacked cartridges are troublesome in the manufacturing process in which they must be restrained by using the fixing member so as to become one body again. Further, since the completed cell cartridge assembly must be assembled with other electrical components including the separately manufactured sensing assembly, additional housing and assembling member for assembling the cell cartridge are required.

In manufacturing battery packs as described above, if the number of assembling / fastening portions is increased, the manufacturing process becomes complicated, and the tolerance ratio is likely to increase accordingly. In addition, since the space occupied by the number of components other than the number of secondary battery cells in the battery pack is high, the energy intensity is low and the manufacturing cost is high as the number of components increases.
