Technical Field

The present disclosure relates to a terminal cover and a battery pack including the same.

The present application claims priority from korean patent application No. 10-2018-.

Background

The secondary battery is highly suitable for various products and exhibits excellent electrical properties such as high energy density, and thus is widely used not only for portable devices but also for Electric Vehicles (EV) or Hybrid Electric Vehicles (HEV) driven by a power source. Since the secondary battery can greatly reduce the use of fossil fuels and does not generate byproducts during energy consumption, the secondary battery is receiving attention as a new energy source for improving environmental friendliness and energy efficiency.

The secondary batteries widely used at present include lithium ion batteries, lithium polymer batteries, nickel cadmium batteries, nickel hydrogen batteries, nickel zinc batteries, and the like. The operating voltage of the unit secondary battery cell, i.e., the unit battery cell, is about 2.5V to 4.6V. Therefore, if a higher output voltage is required, a plurality of battery cells may be connected in series to construct a battery pack. In addition, a plurality of battery cells may be connected in parallel to construct a battery pack according to a charge/discharge capacity required for the battery pack. Therefore, the number of battery cells included in the battery pack may be variously set according to a required output voltage or a required charge/discharge capacity.

Meanwhile, when a plurality of battery cells are connected in series or in parallel to construct a battery pack, it is general to first construct a battery module composed of at least one battery cell and then construct the battery pack by using at least one battery module and adding other components. Here, the battery cells constituting the battery module or the battery pack are generally pouch-type secondary batteries that can be easily stacked one on another.

The conventional battery pack includes: at least one battery module including at least one battery cell; at least one terminal connected to the at least one battery module and to an external power supply or the like; and a battery pack case for exposing the at least one terminal to the outside and enclosing the at least one battery module. Here, the conventional battery pack generally further includes a terminal cover detachably attached to the pack case so as to protect terminals exposed to the outside when carrying the battery pack for transportation or the like. The conventional terminal cover is usually detached from the battery pack case by a rotating operation performed by a user operation.

However, the conventional terminal cover is easily worn by rotation operated by a user, which weakens a fastening force with the battery pack case and damages the battery pack case.

Further, with the conventional terminal cover, it may be difficult for a user to rotate the terminal cover with only a bare hand without using a covering glove. That is, the conventional terminal cover may not be easily operated according to the state of the user's hand.

Therefore, it is desirable to provide a terminal cover that can prevent a battery pack case from being damaged due to disassembly and also allows easier disassembly, and a battery pack including the terminal cover.

Detailed Description

The present disclosure will become more apparent by describing in detail embodiments thereof with reference to the attached drawings. It is to be understood that the embodiments disclosed herein are merely for purposes of better understanding of the present disclosure, and that the present disclosure may be modified in various ways. Additionally, the figures are not drawn to scale and the dimensions of some of the elements may be exaggerated for ease of understanding the present disclosure.

Fig. 1 is a view for illustrating a battery pack according to an embodiment of the present disclosure, and fig. 2 is a sectional view illustrating a main portion of the battery pack of fig. 1.

Referring to fig. 1 and 2, the battery pack 10 may include a battery module 100, a pack case 200, terminals 300, and a terminal cover 500.

The battery module 100 may include at least one battery cell or a plurality of battery cells. The at least one battery cell or the plurality of battery cells may be provided as a secondary battery, for example, a pouch type secondary battery.

At least one battery module 100 or a plurality of battery modules 100 may be provided. The number of the battery modules 100 may be determined according to the required battery capacity.

The battery pack case 200 may enclose the battery modules 100 and form the external appearance of the battery pack 10. The pack case 200 may have an accommodation space for accommodating the battery module 100.

The pack case 200 may have a hook 205.

The hook 205 is used to be coupled with a terminal cover 500 explained later, and the hook 205 may fix a hook 515 of the terminal cover 500 explained later to fix the terminal cover 500 to the battery pack case 200.

The terminals 300 are used to connect the battery module 100 to an external power source, and are electrically connected to the battery module 100. The terminal 300 may be exposed outside the pack case 200.

The terminal 300 may be provided in plurality, and the plurality of terminals 300 may protrude from the pack case 200 so as to be partially exposed outside the outer surface of the pack case 200.

The terminal cover 500 serves to protect the terminals 300, and may cover the terminals 300 exposed from the pack case 200. The terminal cover 500 is mounted to the pack case 200. Here, the terminal cover 500 may be detachably mounted to the pack case 200 for connection between the terminal 300 and an external power source.

The terminal cover 500 may include a cover body 510 and a detachment guide unit 530.

When the terminal cover 500 is mounted to the pack case 200, the cover 510 may cover the terminals 300. The cover 510 may be made of an elastically deformable soft material.

The cover 510 may be detachably coupled to the pack case 200 by a hooking manner.

To this end, the cover 510 may have a hook 515.

A hook portion 515 is provided at one side of the bottom of the cover 510, and may be detachably coupled to the battery pack case 200 by a hooking manner. Specifically, the hook portion 515 may be detachably coupled to the hook portion 205 of the battery pack case 200 by a hook manner.

The detachment guide units 530 are provided at both side surfaces of the cover 510, and may be integrally formed with the cover 510. In addition, the detachment guide unit 530 may be made of the same material as the cover 510. Accordingly, the detachment guide unit 530 may be made of the same elastically deformable soft material as the cover 510.

The detachment guide unit 530 may release the hook of the cover 510 according to the user's pressing. Specifically, the detachment guide unit 530 is spaced apart from the hook 515 by a predetermined distance, and the detachment guide unit 530 may be elastically deformed by the user's pressing to separate the hook 515 from the battery pack case 200, thereby releasing the hook.

The detachment guide unit 530 may be spaced apart from the battery pack case 200 by a predetermined distance so as to be elastically deformed. Accordingly, a predetermined space S may be formed between the detachment guide unit 530 and the pack case 200.

Hereinafter, the releasing operation of the terminal cover 500 according to this embodiment will be described in more detail.

Fig. 3 and 4 are views for illustrating a disassembly operation of a terminal cover of the battery pack of fig. 1.

Referring to fig. 3 and 4, when the battery pack 10 is carried for transportation or the like, in the battery pack 10, the terminal cover 500 may be mounted to the pack case 200 in a hooking manner to protect the terminals 300.

Thereafter, if the carrying transportation or the like of the battery pack 10 is completed, the terminal cover 500 may need to be detached from the pack case 200 to make a connection between the terminal 300 and an external power source.

When detaching the terminal cover 500, a user such as a worker may press both sides of the detachment guide units 530 disposed at both sides of the cover body 510 of the terminal cover 500. If the detachment guide units 530 disposed at the left and right sides of the cover 510 are elastically deformed near the predetermined space S according to the user' S pressing, the upper and lower sides of the cover 510 may also be elastically deformed in the vertical direction.

According to the elastic deformation of the lid body 510 in the vertical direction, the hook portion 515 of the lid body 510 is removed from the hook portion 205 of the battery pack case 200, thereby releasing the hook between the terminal cover 500 and the battery pack case 200.

As described above, in this embodiment, the terminal cover 500 can be detached when the user grasps the detachment guide unit 530, instead of using the conventional rotation structure. Therefore, in this embodiment, since the elastic force obtained by the pressing of the user is used instead of the frictional force in the conventional rotation structure, it is possible to prevent the battery pack case 200 from being worn or broken due to friction.

Also, in this embodiment, the terminal cover 500 is detached from the battery pack case 200 by elastic deformation caused by pressing of the user, so the terminal cover 500 can be more easily attached or detached by the bare hand of the user.

Fig. 5 is a diagram for illustrating a terminal cover employed in the battery pack of fig. 1 according to another embodiment.

The terminal cover 600 of this embodiment is similar to the terminal cover 500 of the previous embodiment, and thus the following description will focus on features different from the previous embodiment.

Referring to fig. 5, the terminal cover 600 may include a cover body 610, a detachment guide unit 630, and an elastic spacer 650.

The cover 610 and the detachment guide unit 630 are substantially the same as or similar to the cover 510 and the detachment guide unit 530 of the previous embodiment, and thus will not be described in detail.

The elastic spacer 650 is disposed at the inner surface of the cover body 610, and the elastic spacer 650 may be disposed between the inner surface of the cover body 610 and the outer surface of the terminal 300 when the terminal cover 600 is mounted to the battery pack case 200.

The elastic spacer 650 may be made of a rubber material having elasticity. For example, the elastic spacer 650 may be made of silicon rubber, styrene butadiene rubber, or the like.

The elastic spacer 650 of this embodiment is in close contact with the outer surface of the terminal 300 inside the cover body 610, and thus when the terminal cover 600 is mounted to the pack case 200, the terminal cover 600 can be more reliably prevented from being unintentionally released, thereby enhancing the coupling stability of the terminal cover 600.

According to various embodiments as described above, it is possible to provide the terminal cover 500, 600 and the battery pack 10 including the terminal cover 500, 600, which the terminal cover 500, 600 can prevent the pack case 200 from being damaged due to the disassembly.

In addition, according to various embodiments of the present disclosure, the terminal cover 500, 600 and the battery pack 10 including the terminal cover 500, 600, which allow easier detachment, may be provided.

Although the embodiments of the present disclosure have been shown and described, it is to be understood that the present disclosure is not limited to the specific embodiments described, and that various changes and modifications can be made by one skilled in the art within the scope of the present disclosure, and that these modifications should not be construed solely from the technical ideas and viewpoints of the present disclosure.
