Definitions
- the present invention relates to a battery module having a compact structure and excellent heat dissipation characteristics, and a medium-large battery pack including the same.
- a plurality of battery cells in which an electrode assembly is embedded in an electrode assembly accommodating part includes the electrode assembly accommodating parts.
- a heat dissipation fin embedded in the module case in a state of being arranged in a lateral direction so as to be adjacent to each other and interposed in close contact between the adjacent electrode assembly accommodating parts; And a hollow structure in which a refrigerant flows therein, and a refrigerant conduit mounted on the heat dissipation fins along the outer circumferential surface of the electrode assembly accommodating unit.
- the battery module includes a cooling member mounted between the battery cells. And it relates to a medium-large battery pack comprising such a battery module.
- the secondary battery is an electric vehicle (EV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle that has been proposed as a solution for air pollution of existing gasoline and diesel vehicles using fossil fuel. It is attracting attention as a power source such as (Plug-In HEV).
- One or two or four battery cells are used for small mobile devices, whereas medium and large battery modules, which are electrically connected to a plurality of battery cells, are used in medium and large devices such as automobiles due to the necessity of high output capacity.
- the medium-large battery module is preferably manufactured in a small size and weight
- the rectangular battery, the pouch-type battery, etc. which can be charged with high integration and have a small weight to capacity, are mainly used as battery cells of the medium-large battery module.
- a pouch-type battery using an aluminum laminate sheet or the like as an exterior member (battery case) has attracted much attention in recent years due to advantages such as low weight, low manufacturing cost, and easy deformation.
- the battery cells constituting the medium-large battery module are composed of secondary batteries capable of charging and discharging, such a high output large capacity secondary battery generates a large amount of heat during the charging and discharging process.
- the laminate sheet of the pouch-type battery widely used in the battery module is coated with a low thermal conductivity polymer material, it is difficult to effectively cool the temperature of the entire battery cell.
- a vehicle medium-large battery pack including a plurality of medium-large battery modules and a high output large capacity battery requires a cooling system for cooling the battery cells embedded therein.
- a battery module mounted in a medium-large battery pack is generally manufactured by stacking a plurality of battery cells with high density, and stacking adjacent battery cells at regular intervals to remove heat generated during charging and discharging.
- the battery cells themselves are sequentially stacked while being spaced at predetermined intervals without a separate member, or in the case of battery cells having low mechanical rigidity, one or more combinations are built in a cartridge or the like to form a unit module and such a unit.
- a plurality of modules can be stacked to form a battery module. Therefore, the separate cartridge has the advantage of increasing the mechanical rigidity, but has the disadvantage of increasing the size of the entire battery module.
- the flow path of the refrigerant is formed between the battery cells or the battery modules so as to effectively remove the heat accumulated between the stacked battery cells or battery modules.
- the cooling structure is a water-cooled cooling system
- the design of the cooling pack is very complicated
- the cooling member or the heat conductive member is mounted at a specific portion, the overall size of the battery pack becomes larger.
- the present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.
- an object of the present invention is to provide a battery module that can maximize the cooling efficiency by being mounted between the battery cells, the cooling member including a refrigerant conduit mounted on the heat radiation fins.
- Still another object of the present invention is to provide a battery module in which a refrigerant conduit is positioned along an outer circumferential surface of an electrode assembly accommodating portion, so that the cooling member itself can be used as a member for fixing the battery cell and increasing mechanical rigidity.
- the battery module according to the present invention for achieving the above object is a plurality of battery cells in which the electrode assembly of the anode / separator / cathode structure is built in the electrode assembly accommodating portion, so that the electrode assembly accommodating portions are adjacent to each other, in the lateral direction It is arranged in the module case in an arranged state,
- the heat dissipation fin is mounted at the interface of the battery cells and the refrigerant conduit is mounted on the heat dissipation fin, so that the heat generated from the battery cell is conducted to the heat dissipation fin, and the heated heat dissipation fin is directly cooled by the refrigerant conduit through which the refrigerant flows. It is possible to exhibit high cooling efficiency without using a separate member such as a thermally conductive member.
- a refrigerant conduit is mounted on the heat dissipation fin along the outer circumferential surface of the electrode assembly accommodating part to fix the battery cell, it provides a stable laminated structure of the battery cell even if the battery cell is not embedded in a separate cartridge and provides mechanical rigidity. As a result, it is possible to construct a very compact battery module with excellent structural stability as a result.
- the battery cell is preferably a plate-shaped battery cell having a thin thickness and a relatively wide width and length so as to minimize the overall size when stacked for the configuration of the battery module.
- a preferred example of such a plate-shaped battery cell is the electrode assembly is built in the electrode assembly accommodating portion formed in the battery case of the laminate sheet comprising a metal layer and a resin layer, the sealing portion sealed by heat fusion on the outer peripheral surface of the electrode assembly accommodating portion ( Secondary batteries forming the " outer peripheral surface sealing portion ”) may be cited.
- the secondary battery having such a structure may also be referred to as a pouch type battery cell.
- the refrigerant conduit may be located over the entire outer circumferential surface of the electrode assembly accommodating portion, or may be located only in a part thereof. Therefore, when the battery cell includes an electrode assembly accommodating part having four corners as shown in FIG. 1, the refrigerant conduit has a structure corresponding to one corner, a structure corresponding to two corners, and 3. Both structures corresponding to the four corners and structures corresponding to the four corners are possible.
- one or more refrigerant conduits may be provided.
- the two or more refrigerant conduits may be located on different electrode assembly receiver outer circumferential surfaces, respectively, or may be located together on part or in whole of the same electrode assembly receiver outer circumferential surface.
- two or more refrigerant conduits may have the same direction in which the refrigerant flows, may be opposite to each other, and the positions of the refrigerant inlet and the refrigerant outlet may also vary according to the installation method of the refrigerant conduit. Accordingly, of course, all of these various types of structures are included in the scope of the present invention.
- the refrigerant conduit of the cooling member may preferably be of a structure located on the outer peripheral sealing portion. Therefore, when the cooling member is interposed between the battery cells, the refrigerant conduit mounted on the cooling fins increases the structural stability of the battery cell, and enables the cooling member to be effectively fixed to the battery cell.
- the cooling member is not particularly limited as long as it is a material having excellent thermal conductivity in order to improve cooling efficiency.
- the cooling member may be made of a metal material having high thermal conductivity.
- the cooling member may have a structure in which the heat dissipation fin has a plate shape and the refrigerant conduit penetrates the heat dissipation fin horizontally.
- the cooling conduit penetrates the heat radiating fins, thereby maximizing the contact area of the heat radiating fins with the coolant flowing inside the cooling conduit, thereby effectively removing heat generated from the battery cells.
- the cooling member is composed of a heat dissipation fin and a refrigerant conduit having a specific structure as defined above, and may be a structure in which the heat dissipation fin and the refrigerant conduit are integrally formed to further improve the cooling efficiency.
- the refrigerant conduit may be bent to have a structure in close contact with the outer peripheral surface of the electrode assembly accommodating portion.
- the cooling member is effectively fixed by the refrigerant conduit bent along the outer circumferential surface of the electrode assembly accommodating portion, and serves to increase the support capacity of the battery cell, it is necessary to use an additional member for fixing the battery cell when configuring the battery module I don't need it.
- the cooling member is interposed between the battery cells, since the heat dissipation fins may be in close contact with the outer surface of each battery cell, it is possible to exert a heat dissipation effect by heat conduction.
- the height of the refrigerant conduit may be such that the heat dissipation fins of the electrode assembly accommodating portions may be preferably interposed between the electrode assembly accommodating portions so as to effectively support and fix the battery cell accommodating portion from the outside.
- the height may be equal to the sum of the heights of the outer circumferential surfaces.
