Description

Technical Field

[0001] This application claims priority to Korean Patent Application No. 10-2022-0186694 filed in Korea on December 28, 2022, and Korean Patent Application No. 10-2023-0107852 filed in Korea on August 17, 2023, the disclosures of which are incorporated herein by reference.

[0002] The present disclosure relates to a battery pack and a vehicle including the same, and more particularly, to a battery pack capable of guiding uniform distribution of cooling liquid and a vehicle including the same. Background Art

[0003] Secondary batteries have high applicability according to product groups and electrical characteristics such as high energy density, and are therefore generally applied not only to portable devices but also to electric vehicles (EVs) or hybrid electric vehicles (HEVs) driven by electric power sources. Such secondary batteries are gaining attention as a new energy source to improve eco-friendliness and energy efficiency, because they not only have the main advantage of significantly reducing the use of fossil fuels, but also have no byproducts generated by the use of energy.

[0004] Currently widely used secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, etc. The operating voltage of a unit secondary battery cell (i.e., a unit battery cell) is about 2.5V to 4.5V. Therefore, if a higher output voltage is required, a plurality of battery cells can be connected in series to configure a battery pack. In addition, depending on the charge / discharge capacity required by the battery pack, a plurality of battery cells can be connected in parallel to configure a battery pack. Therefore, the number of battery cells included in the battery pack can be set in various ways according to the required output voltage or the required charge / discharge capacity.

[0005] Furthermore, when a plurality of battery cells are connected in series or in parallel to configure a battery pack, a battery module including at least one battery cell is generally configured first, and then a battery pack or a battery rack is configured by using such at least one battery module and adding other components.

[0006] In the case of a conventional battery pack, it is configured to include a battery module including a plurality of battery cells and a battery pack case accommodating the battery module. Here, the battery module includes battery cells and may be provided with a plurality of cooling tubes through which a cooling liquid flows to cool the battery cells.

[0007] However, in the case of a conventional battery pack, when cooling liquid is supplied to a plurality of cooling tubes, it is difficult to uniformly distribute the cooling liquid to each cooling tube, resulting in uneven flow of the cooling liquid, thereby causing a problem of deteriorating cooling performance.

Also, the battery module 100 may include a module case for accommodating the battery cells 110.

[0056] The battery cell 110 may be provided in various types. For example, the battery cell 110 may include a square battery cell (not shown) or a pouch-type battery cell (not shown). The pouch-type battery cell may have a structure in which a unit cell arranged in the order of a positive plate-diaphragm-negative plate or a bi-battery arranged in the order of a positive plate-diaphragm-negative plate-diaphragm-positive plate-diaphragm-negative plate is stacked in multiples according to the battery capacity. In addition, the pouch-type battery cell may have an electrode lead. The electrode lead is a terminal that is exposed to the outside and connected to an external device, and may be made of a conductive material. The electrode lead may include a positive lead and a negative lead.

[0057] Alternatively, if Figures 2 to 5 As shown, the battery cell 110 may include a cylindrical battery cell. That is, the battery cell 110 provided in the battery pack 10 according to an embodiment of the present disclosure may vary, but for ease of description, the following description will focus on the case where the battery cell 110 is a cylindrical battery cell.

Here, the positive electrode plate and the negative electrode plate can be formed in a sheet shape. That is, the electrode assembly can be a wound electrode assembly. The electrode assembly can have any winding structure known in the related art without limitation.

[0061] The positive electrode active material is applied on one or both sides of the positive electrode plate, and the negative electrode active material is applied on one or both sides of the negative electrode plate. The positive electrode active material coated on the positive electrode plate and the negative electrode active material coated on the negative electrode plate can be used without limitation as long as they are active materials known in the art.

Therefore, the battery can may have the same polarity as the negative electrode plate (ie, negative electrode), but is not limited thereto.

[0065] Also, a gap of a predetermined size is formed between the battery can and the electrode assembly (between the battery can and the positive current collector plate when the positive current collector plate is coupled to the electrode assembly), and an insulator may be interposed between the gap. The battery can may be made of a conductive metal such as aluminum, steel, stainless steel, etc., but is not limited thereto.

[0066] The positive current collector plate is electrically connected to the positive plate, and, for example, the positive current collector plate may be connected to the positive plate at the top of the electrode assembly.

[0067] The cell terminal is made of a conductive metal material and is electrically connected to the positive current collector plate. Also, the cell terminal is electrically connected to the positive plate of the electrode assembly through the positive current collector plate, thereby having a positive polarity. That is, the cell terminal can be used as a positive terminal.

[0068] The negative current collector plate is electrically connected to the negative electrode plate. The negative current collector plate may be made of a conductive metal material such as aluminum, steel, copper, nickel, and the like.

Also, if necessary, the cross section of the coupling portion 311 may be formed in more various shapes, such as a rectangle, a triangle, or other shapes. Here, the interior of the coupling portion 311 is empty, and the cooling liquid may move through the interior of the coupling portion 311.

[0078] Also, the plurality of coupling portions 311 may be spaced apart from each other to have a predetermined interval, and the cooling liquid flowing through the distribution pipe 310 moves to the cooling pipe 120 through the plurality of coupling portions 311 .

[0079] The coupling portion 311 is formed to protrude from an end of the dispensing pipe 310 , wherein the coupling portion 311 may be integrally formed with the dispensing pipe 310 , or may be manufactured separately from the dispensing pipe 310 and then coupled to the dispensing pipe 310 .

For example, the two second connection pipes 322 may be connected to the 3-way port on both sides relative to the 3-way port, respectively, and one first connection pipe 321 provided in a direction crossing the two second connection pipes 322 may be connected to the 3-way port.
