Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery box, and further to an energy storage system including the battery box. Background Technology

[0002] A battery box, also known as a battery pack or battery array, is a structure used to house and protect battery cells. It is widely used in electric vehicles, energy storage systems, and other products requiring high-capacity power. Internally, it typically houses battery cells, a battery management system, electrical connections, and a thermal management system. The battery box not only provides physical protection for its internal components, preventing damage from external impacts, but also helps dissipate heat. As a crucial component of energy storage systems, energy storage battery boxes are widely used in various types of energy storage products.

[0003] Energy storage battery boxes generally have multiple installation methods, such as hanging installation or stacking installation. Stacking installation also includes stacking along different directions of the battery box. Battery boxes usually have indicator lights on the side for users to observe. When different stacking installation methods are used, the indicator lights on the side of the battery box may not be exposed, thus affecting the user's ability to observe the status information of the battery box from the outside. If indicator lights are set on different exposed sides for different installation methods, the cost is high and it is not possible to make a single battery box suitable for different stacking methods, thus failing to meet the requirements of different stacking methods of battery boxes.

Detailed Implementation

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0049] In energy storage batteries, battery boxes need to be stacked in different ways to meet the needs of different usage scenarios due to different usage requirements. The indicator lights on the outside of the battery box are usually set on one side. When different stacking methods are used, there will be situations where the indicator lights on the outside of the battery box cannot be exposed. Therefore, it is not convenient for users to observe from the outside, nor is it convenient for users to know the battery status information. It is impossible to effectively expose the indicator lights while taking into account different stacking methods of the battery box, and it also cannot meet the different stacking requirements of the battery box.

[0050] Figure 1 This is a perspective view of a battery box according to one embodiment of the present application. The battery box can be used for energy storage and includes: a box body 1 configured to have at least a first end face 11 and a second end face 12 adjacent thereto on its outer wall; a light-transmitting structure 2 disposed at the junction of the first end face 11 and the second end face 12 and extending to both of them for a certain length; a light guide member 3 disposed inside the box body 1; and a light-emitting unit 4 disposed beside the light guide member 3. The light guide member 3 is configured to have at least a light guide strip 31 that can be installed on the light-transmitting structure 2; the light-emitting unit 4 is configured to transmit light to the light-transmitting structure 2 through the light guide strip 31 to reflect the box body 1.

[0051] It can be understood that by setting a light-transmitting structure 2 on the housing 1, the light emitted by the light-emitting unit 4 can be easily transmitted to the outside of the housing 1. The light guide component 3 set inside the housing 1 can guide the light of the light-emitting unit 4 to the position of the light-transmitting structure 2, and cooperate with the light-transmitting structure 2 through the light guide strip 31 to form an indicator light for the user to observe from the outside. Since the light-transmitting structure 2 is distributed on two adjacent first end faces 11 and second end faces 12, the light-transmitting area of ​​the battery box indicator light is effectively increased, making it easy for the user to observe the indicator light from different directions. This facilitates the adaptation to different installation methods of the battery box, and can achieve the exposure of the indicator light while taking into account different stacking methods of the battery box, thus meeting the requirements of different stacking methods of the battery box.

[0052] It should be noted that the first end face 11 and the second end face 12 can be a plane at a certain angle to each other, or a curved surface with a certain curvature between them. In this embodiment, the focus is on setting the light-transmitting structure 2 at the junction of different planes or curved surfaces, so as to increase the user's observation angle. Therefore, the specific structure of the first end face 11 and the second end face 12 can be selected as a plane or a curved surface as needed. This embodiment does not make specific limitations here.

[0053] In addition, the main function of the light-transmitting structure 2 is to cooperate with the light guide strip 31 to form the indicator light of the battery box. Since the light-transmitting structure 2 is distributed on two connected different planes, multiple indicator lights spanning the two planes can be formed at the corner position of the two connecting surfaces. Therefore, the specific arrangement of the light-transmitting structure 2 and the specific shape of the light guide strip 31 can be selected as needed. This embodiment does not make specific limitations here.

[0054] The following will illustrate further specific implementations or refinements of the battery box through exemplary description, in order to further improve it or for other improvement considerations.

[0055] In one embodiment, reference is made to... Figure 5 and Figure 6 The light-transmitting structure 2 is configured to have a light-transmitting opening that extends through the housing 1, and the light guide strip 31 can be embedded in the light-transmitting opening to achieve the installation of both.

[0056] It can be understood that by setting the above-mentioned light-transmitting structure 2 as a through-hole light-transmitting opening, it is convenient to embed the above-mentioned light guide strip 31 into the light-transmitting opening, so that the two work together to form an exposed indicator light. The structure is simple and also convenient to use the light-transmitting structures 2 distributed on the two end faces to achieve light transmission in different directions.

[0057] Further reference Figure 5 and Figure 6 Multiple light-transmitting openings are arranged sequentially along the junction of the first end face 11 and the second end face 12. The light guide strips 31 are distributed sequentially along the length of the light guide member 3 and are arranged in one-to-one correspondence with the light-transmitting openings.

[0058] It is easy to see that by arranging multiple light-transmitting openings sequentially along the junction of the first end face 11 and the second end face 12, and by setting the light guide strips 31 one-to-one with the light guide components 3, the two can cooperate to form multiple indicator lights to display different states of the battery box.

[0059] Furthermore, the light-transmitting opening is configured as a strip-shaped opening distributed on the first end face 11 and the second end face 12, and the light guide strip 31 is configured as a strip light strip correspondingly embedded in the strip-shaped opening.

[0060] It can be seen that by setting the above-mentioned light-transmitting opening as a strip opening, it is easy to form a strip indicator light together with the strip light strip, so that users can observe the strip indicator light from different directions.

[0061] For example, the light-transmitting openings can be equally spaced along the junction of the first end face 11 and the second end face 12, or they can be irregularly distributed along the junction of the two. The specific distribution method can be adjusted as needed, and this embodiment does not make specific limitations here.

[0062] For example, the light-transmitting opening can be set in the shape of a strip, or in the shape of a circle or a square, and the light guide strip 31 can be set accordingly to achieve corresponding installation of the two. The specific shape of the light guide strip is not a limiting provision of this embodiment.

[0063] In another embodiment, the light-transmitting structure 2 is configured as a bent light-transmitting plate (not shown in the figure) disposed at the junction of the first end face 11 and the second end face 12, and the light guide strip 31 is configured as a bent light strip that is attached to and installed on the inner side of the bent light-transmitting plate.

[0064] It is easy to see that by setting the above-mentioned light-transmitting structure 2 as a bent light-transmitting plate, the first end face 11 and the second end face 12 of the bent light-transmitting plate box 1 can be installed together, thereby achieving effective light transmission at the junction of the two end faces. The bent light strip can be used in conjunction with the bent light-transmitting plate. The structure is simple and it is also convenient to install indicator lights on both end faces. Of course, a bent light-transmitting plate plus an ordinary light strip can also be used, as long as light transmission in different directions at the bend can be achieved. This embodiment does not make specific limitations here.

[0065] Based on this, refer to Figure 2 , Figure 3 and Figure 4 The light guide component 3 has a first mounting surface and a second mounting surface that are at a certain angle, and the two are configured to be attached to the inner walls of the two sides of the housing 1 opposite to the first end face 11 and the second end face 12, respectively. The light guide strip 31 is disposed at the junction of the first mounting surface and the second mounting surface and extends to both of them by a certain length.

[0066] It can be understood that by setting a first mounting surface and a second mounting surface on the light guide component 3, it is easy to attach it to the inner wall of the two boxes 1 opposite to the first end face 11 and the second end face 12, thereby achieving effective attachment and installation of the light guide component 3 and the box 1, and also ensuring the connection stability of the light guide component 3 and the box 1.

[0067] In actual operation, this embodiment should be referred to Figure 2Both the first mounting surface and the second mounting surface are provided with a recessed adhesive groove 32 located around the light guide strip 31. The recessed adhesive groove 32 is configured to provide adhesive space for the light guide component 3 and the inner wall of the housing 1.

[0068] It is easy to see that by opening recessed adhesive grooves 32 on both the first and second mounting surfaces, located around the light guide strip 31, it is convenient to bond the light guide component 3 to the corner of the housing 1, further ensuring the close fit between the light guide component 3 and the battery housing 1, and improving the stability of the connection between the two.

[0069] In one example of this embodiment, reference is made to... Figure 1 and Figure 2 The first end face 11 and the second end face 12 form a 90-degree angle, and the first mounting surface and the second mounting surface form a 90-degree angle.

[0070] It can be understood that by forming a 90-degree angle between the first end face 11 and the second end face 12, and a 90-degree angle between the first mounting surface and the second mounting surface, it is convenient to attach the first mounting surface and the second mounting surface to the inner sidewalls corresponding to the first end face 11 and the second end face 12 respectively, thereby achieving an effective connection between the two.

[0071] Specifically, the vertical distribution of the first end face 11 and the second end face 12 facilitates the stacking of the battery box in different ways. Furthermore, due to the distribution of the light-transmitting structure 2 and the light guide component 3, while ensuring different stacking methods, the effective exposure of the indicator lights is also taken into account, thereby realizing different stacking of the battery box.

[0072] For example, the included angle between the first end face 11 and the second end face 12 can also be adjusted as needed, such as to 30 degrees, 45 degrees, 60 degrees, etc., or other angles. The first mounting surface and the second mounting surface correspond to each other. Therefore, the included angle between the first end face 11 and the second end face 12 can be selected as needed. This embodiment does not make specific limitations here.

[0073] In a more specific implementation, such as Figures 2-4 As shown, the light guide component 3 includes: a first guide plate 33 and a second guide plate 34, and a support portion 35 disposed inside the joint of the first guide plate 33 and the second guide plate 34. The first guide plate 33 and the second guide plate 34 are configured to form a certain angle between them. The first mounting surface and the second mounting surface are respectively formed on the first guide plate 33 and the second guide plate 34. A plurality of support portions 35 are provided at intervals along the length direction of the first guide plate 33 and the second guide plate 34. The light-emitting unit 4 is mounted on the support portion 35.

[0074] In this arrangement, by setting the light guide component 3 as a first guide plate 33, a second guide plate 34 and a support part 35, it is convenient to use the first guide plate 33 and the second guide plate 34 to achieve close installation with the inner wall of the box 1, and the support part 35 is convenient to install the light-emitting unit 4, which cooperates with the light-transmitting structure 2 located in the box 1 to achieve detachable installation of the two.

[0075] In actual operation, this embodiment should be referred to Figure 3 and Figure 4 It also includes: a light-shielding member 5 disposed on the side of the light guide member 3 away from the light guide strip 31, the light-shielding member 5 being configured to be hollow inside and disposed in a one-to-one correspondence with the light guide strip 31, the light-shielding member 5 extending from the position of the light guide strip 31 to the light-emitting unit 4.

[0076] It is easy to see that by using the light-shielding member 5 set on the other side of the light guide member 3, the light emitted by the light-emitting unit 4 can be easily guided to the position of the light guide strip 31. Since the light-shielding member 5 and the light guide strip 31 are set one-to-one, the cross-lighting of the lights of different light guide strips 31 can be effectively avoided, ensuring the independent light transmission of the indicator lights formed by each light guide strip 31, and further improving the light guiding independence of the light guide strip 31.

[0077] For example, the light-shielding component 5 can be a black light-shielding column embedded inside the support portion 35, which is hollow inside and opaque on the outside, thereby achieving effective light guiding while preventing light transmission. Of course, the light-shielding component 5 can also be other types of light-shielding components, which are not specifically limited in this embodiment.

[0078] In actual operation, this embodiment should be referred to Figure 7 and Figure 8 The light-emitting unit 4 includes: a lamp plate 41 detachably installed on the side of the light guide member 3 away from the light guide strip 31, and lamp beads installed one-to-one inside the light shielding member 5 and configured to be electrically connected to the lamp plate 41.

[0079] It can be understood that by using the lamp panel 41 and the corresponding lamp beads set inside the light-shielding member 5, it is convenient to emit light from the corresponding light guide strip 31, so as to achieve effective light emission of the light guide strip 31.

[0080] Further reference Figure 4 , Figure 7 and Figure 8 It also includes: a plurality of buckles 6 arranged on the side of the light guide member 3 away from the light guide strip 31, and a limiting post 7 provided next to the buckle 6, wherein one side of the lamp plate 41 is pressed against the limiting post 7, and the other side is pressed and fixed by the buckle 6.

[0081] It is easy to see that the above-mentioned buckle 6 and limiting post 7 make it easy to detachably install the lamp plate 41 on the light guide component 3. Specifically, the side of the lamp plate 41 with lamp beads can be pressed onto the limiting post 7 first, and then the other side can be pressed and fixed by the buckle 6 located on the periphery of the lamp plate 41.

[0082] Of course, the above-mentioned light panel 41 can also be installed in other ways, such as screws or bolts, but this embodiment does not make specific limitations here.

[0083] In actual operation, the light guide strip 31 and the light guide component 3 are integrally injection molded in this embodiment.

[0084] In one embodiment, the light guide strip 31 is configured as a SOC signal light strip, and / or the light guide strip 31 is configured as a running status light strip, and / or the light guide strip 31 is configured as an alarm light strip.

[0085] For example, the light guide strip 31 and the light guide component 3 can be integrally injection molded or installed separately. This embodiment does not make specific limitations here.

[0086] For example, the light guide strip 31 mentioned above can be a SOC signal light strip, or a running status light strip, or an alarm light strip. Of course, it can also be other types of indicator light strips. This embodiment does not make specific limitations here.

[0087] This embodiment also provides an energy storage system, including multiple battery boxes as described above, which are stacked along their length or width.

[0088] According to the battery box provided in this application, by applying the above-mentioned battery box to an energy storage system, a light-transmitting structure 2 is provided on the box body 1 to facilitate the light emitted by the light-emitting unit 4 to be transmitted to the outside of the box body 1. The light guide component 3 provided inside the box body 1 can guide the light of the light-emitting unit 4 to the position of the light-transmitting structure 2, and cooperate with the light-transmitting structure 2 through the light guide strip 31 to form an indicator light for the user to observe from the outside. Since the light-transmitting structure 2 is distributed on two adjacent first end faces 11 and second end faces 12, the light-transmitting area of ​​the battery box indicator light is effectively increased, making it easy for the user to observe the indicator light from different directions. It is easy to adapt to different installation methods of the battery box, and can realize the exposure of the indicator light while taking into account different stacking methods of the battery box, thus meeting the requirements of different stacking methods of the internal battery boxes of the energy storage system.

[0089] For example, the battery boxes described above can be stacked along their length or their width, or they can be mounted on a wall. The specific installation method can be selected and adjusted according to the actual situation, and this embodiment does not make specific limitations here.

[0090] The above examples primarily illustrate the battery box and energy storage system including the battery box of this application. Although only some embodiments of this application have been described, those skilled in the art should understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are considered illustrative rather than restrictive, and this application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of this application.
