Description

Technical Field

[0001] This application relates to the field of batteries, and in particular to a battery and an electrical device. Background Technology

[0002] A battery typically consists of a cell and a casing, with the casing used to encapsulate and support the cell. However, cells generate a significant amount of heat during use. If this heat is not dissipated in a timely manner, it can lead to excessive temperature differences between the inside and outside of the cell, affecting its performance. Utility Model Content

[0003] This application provides a battery and an electrical device that aims to improve the problems of uncooled battery cells and large temperature differences between the inside and outside of the battery.

[0004] To achieve the above technical effects, one technical solution adopted in this application is: to provide a battery, the battery including a housing, the housing including: a base plate; a frame installed around the periphery of the base plate, and the frame and the base plate defining an upwardly open accommodating cavity; the accommodating cavity for accommodating battery cells; and a heat exchange tube attached to the side of the frame away from the accommodating cavity for heat exchange of the battery cells accommodated in the accommodating cavity.

[0005] The heat exchange tubes are located on the outer surface of the enclosure. They exchange heat with the battery cells inside the housing, solving the problems of uncooled battery cells and excessive temperature differences between the inside and outside. In addition, the external placement of the heat exchange tubes does not occupy internal housing space, improving the utilization of housing space and facilitating the maintenance and replacement of the heat exchange tubes.

[0006] In some embodiments, the heat exchange tube is fixed to the side of the frame by an adhesive; wherein the adhesive is a thermally conductive adhesive.

[0007] The heat exchange tubes are fixed to the side of the frame using an adhesive, ensuring full contact between the tubes and the frame for convenient heat exchange. Preferably, the adhesive is a thermally conductive adhesive, which further facilitates heat exchange between the heat exchange tubes and the battery cells inside the frame.

[0008] In some embodiments, the frame includes two side frames disposed along a first direction and extending along a second direction, the two side frames being disposed opposite each other on both sides of the base plate; wherein the heat exchange tube is disposed on the side frames; the first direction and the second direction are perpendicular to each other.

[0009] The frame is surrounded by four borders, of which the front and rear borders are used for water inlet or outlet. Therefore, preferably, the heat exchange tubes are set on the side borders, either on one side border or on two side borders.

[0010] In some embodiments, any of the side frames includes a first side beam and a second side beam, the first side beam being disposed perpendicular to the base plate along a second direction; the second side beam being disposed at the end of the first side beam away from the base plate and extending along a third direction; wherein the third direction is perpendicular to both the first direction and the second direction.

[0011] The first side beam and the bottom plate define the receiving cavity, and the second side beam is set in the direction away from the receiving cavity to cover one side surface of the heat exchange tube, thereby providing a certain degree of protection for the heat exchange tube.

[0012] In some embodiments, any of the side frames further includes a support beam fixed to the side of the first side beam away from the receiving cavity, for supporting the first side beam.

[0013] The support beam is fixed to the side of the second side beam away from the receiving cavity, and is used to support and reinforce the second side beam.

[0014] In some embodiments, the support beam includes a first support beam that extends along the first direction and is fitted to a side of the first side beam away from the receiving cavity. The end face of the first support beam away from the bottom plate is parallel to and spaced apart from the second side beam.

[0015] This configuration allows the heat exchange tubes to be positioned at the interval between the first support beam and the second side beam.

[0016] In some embodiments, the dimension of the first support beam along the third direction is larger than the dimension of the heat exchange tube along the third direction, and the end face of the first support beam away from the base plate forms a groove with the second side beam to accommodate the heat exchange tube.

[0017] The lower edge of the heat exchange tube is defined by the second end of the first support beam, and the upper edge of the heat exchange tube is defined by the extension length of the second side beam along the first side beam, thereby confining the heat exchange tube between the first support beam and the second side beam, which serves to protect the heat exchange tube.

[0018] In some embodiments, the support beam further includes a second support beam, which is fixedly connected to the end of the first support beam away from the base plate and extends along the third direction, parallel to and spaced apart from the second side beam; wherein the second support beam and the second side beam form a groove for accommodating the heat exchange tube.

[0019] This design limits the placement of the heat exchange tubes while also increasing the outward extension length of the frame, which can be used to fix the cover plate of the enclosure.

[0020] In some embodiments, the heat exchange tube is smaller in size along the third direction than the second side beam along the third direction, and smaller in size than the second support beam along the third direction.

[0021] This design protects and supports the heat exchange tubes.

[0022] In some embodiments, the frame further includes a front frame and a rear frame disposed opposite to each other, the front frame being provided with an inlet communicating with the heat exchange tube.

[0023] This configuration maximizes the length of the heat exchange tubes covering the side frame, thereby improving heat exchange efficiency.

[0024] In some embodiments, the rear frame is provided with a water outlet communicating with the heat exchange tube at one end near the heat exchange tube.

[0025] This design ensures sufficient contact area between the heat exchange tubes and the side frame.

[0026] In some embodiments, the front frame is further provided with a water outlet, and the rear frame is provided with a connecting pipe that communicates with the heat exchange tube.

[0027] The heat exchange tubes on the two side frames are connected by a connecting pipe on the rear frame, thus forming a heat exchange tube that surrounds the frame and increases the heat exchange area.

[0028] This application also provides an example of an electrical device comprising a battery as described in any of the above embodiments.

[0029] By placing the heat exchange tubes on the outer surface of the enclosure to exchange heat with the battery cells inside the housing, the problems of uncooled battery cells and excessive temperature differences between the inside and outside can be solved. In addition, the external placement of the heat exchange tubes does not occupy the internal housing space, improving the utilization rate of the housing space and facilitating the maintenance and replacement of the heat exchange tubes.

Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0048] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0049] In this application example, "multiple" refers to at least two (including two).

[0050] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components. As used in this application, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0051] The terms “a” and “an” used in this specification may mean one, but may also be used interchangeably with “at least one” or “one or more”. The term “about” generally means the mentioned value plus or minus 10%, or more specifically, plus or minus 5%. The term “or” used in the claims means “and / or” unless it is explicitly stated that it refers only to alternatives.

[0052] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0053] The battery mentioned in the embodiments disclosed in this application refers to a single physical module comprising one or more battery cells to provide a predetermined voltage and capacity. For example, the battery mentioned in this application may include a cell and a packaging box, and the cell may be a battery module or battery pack formed by combining multiple battery cells.

[0054] In high-power applications such as electric vehicles, battery applications involve three levels: individual battery cells, battery cells, and the battery pack. A battery cell is formed by electrically connecting a number of individual battery cells together and placing them in a frame to protect them from external shocks, heat, and vibration. The battery pack is the final state of the battery system installed in an electric vehicle. A battery typically includes a casing for encapsulating one or more individual battery cells. The casing prevents liquids or other foreign matter from affecting the charging or discharging of the individual battery cells. The casing generally consists of a body and a cover. The body typically includes a base plate and outer side plates. The outer side plates extend from the edge of the base plate, generally perpendicular to it, forming an open accommodating space for housing the individual battery cells. The cover is positioned over the opening of the accommodating space, opposite the base plate, and connects to the outer side plates. The body and cover can be detachably connected or sealed. Currently, most batteries are manufactured by assembling a battery management system (BMS), thermal management components, and various control and protection systems on one or more battery modules or cells.

[0055] In some cases, a battery cell includes a casing and a bare cell, with the bare cell housed within the enclosure of a casing. Because the bare cell is housed within the casing, it requires temperature equalization or heat transfer. However, existing temperature equalization structures or heat conduction devices can only equalize or dissipate the heat generated by the bare cell. When the heat level of the bare cell becomes excessively high, it may cause spontaneous combustion, leading to combustion or damage to the battery cell and posing a safety hazard. This application addresses the problem of uncooled cells and excessive temperature differences between the inside and outside by installing heat exchange pipes on the outer wall of the casing to exchange heat with the cells within the enclosure.

[0056] To address the issues of uncooled battery cells and large temperature differences between the inside and outside, a battery and power supply device were designed.

[0057] like Figure 1As shown, this figure is a simplified schematic diagram of an electrical device, specifically a vehicle 1, according to some embodiments. Vehicle 1 can be a fuel-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid vehicles, or range-extended vehicles, etc. A battery 10 can be installed inside vehicle 1, for example, at the bottom, front, or rear of vehicle 1. The battery 10 can be used to power vehicle 1; for example, it can serve as the operating power source for vehicle 1. Vehicle 1 may also include a controller 30 and a motor 40. The controller 30 controls the power supply from the battery 10 to the motor 40, for example, to meet the power requirements for starting, navigation, and driving of vehicle 1. In another embodiment of this application, the battery 10 can not only serve as the operating power source for vehicle 1 but also as the driving power source, replacing or partially replacing fuel or natural gas to provide driving power to vehicle 1. The battery 10 referred to below can also be understood as a battery comprising multiple cells 20.

[0058] Figure 2 and Figure 3 Exploded views of the battery 10 according to some embodiments are shown. For example... Figure 2 and Figure 3 As shown, the battery 10 includes multiple battery cells 20 and a busbar 12 for electrically connecting the multiple battery cells 20. To protect the battery cells 20 from external liquids or foreign matter, the battery 10 includes a casing 11 for encapsulating the multiple battery cells and other necessary components, such as... Figure 2 and Figure 3 As shown. In some embodiments, the enclosure 11 may include a cover 111 and a housing 112. The battery 10 may also include a support 114 extending between the cover 111 and the housing 112. The support 114 may extend from the base plate 112a of the housing 112 toward the cover 111 in a direction perpendicular to the base plate 112a. The cover 111 and the housing 112 are hermetically combined together to jointly enclose an electrical cavity 11a for accommodating a plurality of battery cells 20. In other embodiments, the cover 111 and the housing 112 may also be loosely combined with each other.

[0059] Figure 4 This is a schematic diagram of the overall structure of the housing according to some implementation methods. Figure 5 This is a schematic diagram of the disassembly structure of the enclosure according to some embodiments. Figure 6 This is a top view of the housing according to some embodiments. For example... Figures 4-6As shown, the housing 112 includes a base plate 112a and a frame 112b disposed around the base plate 112a. The frame 112b and the base plate 112a define an upwardly open receiving cavity 110. This receiving cavity 110 is used to accommodate the battery cell 20. The housing 112 also includes a heat exchange tube 113, which is fitted against the side of the frame 112b away from the receiving cavity 110.

[0060] The housing 112 is used to encapsulate the battery cells. The base plate 112a is the bottom of the housing 112 and is used to support the battery cells. A frame 112b is arranged around the base plate 112a, forming the side walls of the housing 112. The accommodating cavity 110 is the space within the housing 112 for placing the battery cells. Heat exchange tubes 113 are located on the outside of the housing 112 and are used to exchange heat with the battery cells within the accommodating cavity 110.

[0061] By placing the heat exchange tubes on the outer surface of the enclosure, heat can be exchanged between the battery cells inside the housing, solving the problems of uncooled battery cells and excessive temperature differences between the inside and outside. In addition, the external placement of the heat exchange tubes does not occupy the internal housing space, improving the utilization rate of the housing space and facilitating the maintenance and replacement of the heat exchange tubes.

[0062] In some examples, the heat exchange tube 113 is attached to the side of the frame 112b by adhesive 1124. In other examples, the heat exchange tube 113 may also be fixed to the side of the frame 112b by other fixing structures, which are not limited here. In this example, the adhesive is preferably a thermally conductive adhesive. In this example, the adhesive is relatively thin, and heat transfer can be achieved even if it is not a thermally conductive adhesive.

[0063] Colloid 1124 is a substance with adhesive properties, which can be glue or double-sided tape, used to bond two objects together and fix them in place.

[0064] By fixing the heat exchange tube 113 to the side of the frame 112b of the housing 112, the heat exchange tube is in full contact with the frame, which facilitates heat exchange and can effectively improve the heat exchange capacity between the battery cell and the outside world.

[0065] In some specific examples, frame 112b includes two oppositely arranged side borders 1121, a front border 1122, and a rear border 1123. The two side borders 1121 are connected to the front border 1122 and the rear border 1123, forming frame 112b integrally.

[0066] The front frame 1122, the rear frame 1123, and the two side frames 1121 are each a side wall of the frame 112b.

[0067] The frame is composed of four side frames, with the front and rear frames used for water inlet and outlet. Therefore, preferably, the heat exchange tubes are disposed on the side frames, either on one side frame or on two side frames. One-piece molding improves the stability of the frame 112b.

[0068] The two side frames 1121 are set along the first direction X and extend along the second direction Y. The first direction X and the second direction Y are set perpendicular to each other. The first direction X is set along the side length of the base plate 112a and can change direction as the side length changes. Overall, it is a direction parallel to the plane of the base plate 112a. The second direction Y is a direction perpendicular to the plane of the base plate 112a.

[0069] In some examples, at least one heat exchange tube 113 is disposed on one of the side frames 1121. In other examples, there are two heat exchange tubes 113, each disposed on one of the side frames 1121. Please refer to the following for details. Figures 7-8 , Figure 7 This is a partially enlarged structural schematic diagram of the housing according to some embodiments; Figure 8 This is a partially enlarged disassembly diagram of the housing according to some embodiments.

[0070] In this example, the heat exchange tube 113 is arranged on the frame 112b in a direction parallel to the base plate 112a, that is, in a direction parallel to the base plate 112a. In other examples, the heat exchange tube 113 may also be arranged at an angle to the base plate 112a, which is not limited here. The heat exchange tube 113 can be a straight tube or a bent tube (such as a U-shaped tube).

[0071] Figure 9 This is a side view of the housing according to some embodiments. Figure 10 This is a schematic diagram of the cross-sectional structure of the box according to some embodiments. Figure 11 for Figure 10 A partially enlarged structural diagram.

[0072] Further reading Figures 9-11 ,in, Figure 10 for Figure 9 A schematic diagram of the AA section in the diagram. Figure 11 for Figure 10A partially enlarged schematic diagram is shown. In some examples, any side frame 1121 includes a first side beam 11211 and a second side beam 11212. The first side beam 11211 is positioned perpendicular to the base plate 112a along the second direction Y, and multiple first side beams 11211 are fixedly connected to the base plate 112a, defining the receiving cavity 110. The second side beam 11212 is located at the end of the first side beam 11211 away from the base plate 112a and extends along a third direction Z, where the third direction Z is the direction away from the receiving cavity 110, and is perpendicular to both the first direction X and the second direction Y. The second side beam 11212 defines the space for the heat exchange tube 113 along the third direction Z, providing some protection to the upper edge of the heat exchange tube 113. In some specific examples, the angle between the second side beam 11212 and the first side beam 11211 is 90 degrees. In other words, the second side beam 11212 is perpendicular to the first side beam 11211 and is arranged parallel to the base plate 112a. In this example, the cover 111 can be fixed to the second side beam 11212 by screws or other fixing structures to form a sealing box 11.

[0073] The first side beam and the bottom plate define the receiving cavity, and the second side beam is set in the direction away from the receiving cavity to cover one side surface of the heat exchange tube, thereby providing a certain degree of protection for the heat exchange tube.

[0074] In some examples, the side frame 1121 includes a support beam 11213, which is attached to the side of the first side beam 11211 away from the receiving cavity 110 and is fixedly disposed with the first side beam 11211 to enhance the rigidity of the first side beam 11211. One end face of the support beam 11213 abuts against the base plate 112a to support the first side beam 11211.

[0075] The second side beam is reinforced by fixing and supporting it with a support beam.

[0076] In some examples, the support beam 11213 includes at least a first support beam 11213a, which extends along a first direction X and is disposed abutted against the side of the first side beam 11211 facing away from the receiving cavity 110. A first end of the first support beam 11213a abuts against the base plate 112a, and a second end face is parallel to and spaced apart from the second side beam 11212. The first end face is the end face of the first support beam 11213a located near the base plate 112a, and the second end face is the end face of the first support beam 11213a located away from the base plate 112a. A heat exchange tube 113 is disposed on the first side beam 11211 between the second end face of the first support beam 11213a and the second side beam 11212. In this example, the first support beam 11213a is disposed abutted against the first side beam 11211 to enhance the rigidity of the first side beam 11211. The first end of the first support beam 11213a abuts against the base plate 112a, thereby strengthening the support performance of the first side beam 11211. In other examples, the support beam 11213 can also be integrally formed with the side beam. In this example, preferably, the dimension of the first support beam 11213a along the third direction Z is not less than the dimension of the heat exchange tube 113 along the third direction Z, where the dimension refers to the thickness. The second end of the first support beam 11213a and the second side beam 11212 form the sidewall of the groove 1120, and the first side beam 11211 forms the bottom of the groove 1120. The second end of the first support beam 11213a, the second side beam 11212, and the first side beam 11211 form the groove 1120 for accommodating the heat exchange tube 113. The groove 1120 defines the placement position of the heat exchange tube 113 and provides a certain degree of protection for the upper and lower edges of the heat exchange tube 113.

[0077] The heat exchange tube can be placed between the first support beam and the second side beam, forming a groove between the first support beam and the second side beam, which provides a certain degree of protection for the heat exchange tube.

[0078] In other examples, the support beam 11213 includes a first support beam 11213a and a second support beam 11213b. The first support beam 11213b is as described in the examples above. The second support beam 11213b is fixedly connected to the second end of the first support beam 11213a and extends in a third direction Z, that is, in a direction perpendicular to the first side beam 11211 or parallel to the second side beam 11212. The second support beam 11213b is parallel to and spaced apart from the second side beam 11212, and the second support beam 11213b and the second side beam 11212 form the sidewall of the groove 1120. The first side beam 11211 forms the bottom surface of the groove 1120, thereby forming the groove 1120 for accommodating the heat exchange tube 113. In this example, the second support beam 11213b and the second side beam 11212 extend in the same direction. The dimension (extension length) of the second support beam 11213b along the third direction Z is greater than the dimension (extension length) of the second side beam 11212 along the third direction Z, so that the second support beam 11213b protrudes from the second side beam 11212 along the third direction Z. A screw hole can be made in the protruding part of the second support beam 11213b for fixed connection with the cover plate or other external battery structure. In this example, the dimension of the heat exchange tube 113 along the third direction Z is smaller than that of the second side beam 11212 along the third direction Z, and also smaller than that of the second support beam 11213b along the third direction Z, so that the sidewall length of the groove 1120 is greater than the dimension of the heat exchange tube 113 along the third direction Z, thereby allowing the heat exchange tube 113 to be completely accommodated within the groove 1120.

[0079] The lower edge of the heat exchange tube is defined by the second end of the first support beam, and the upper edge of the heat exchange tube is defined by the extension length of the second side beam along the first side beam. This confines the heat exchange tube within the groove formed between the first support beam and the second side beam, thus protecting the heat exchange tube. This design not only defines the position of the heat exchange tube but also increases the outward extension length of the frame for fixing the cover plate of the housing.

[0080] In this example, frame 112b also includes a front border 1122 and a back border 1123 that are set relative to each other.

[0081] In some examples, the front frame 1122 is provided with a water inlet, and the rear frame 1123 is provided with a water outlet. The water inlet and the water outlet are respectively connected to both ends of the heat exchange tube 113, so as to achieve heat exchange for the battery by exchanging the liquid in the heat exchange tube 113.

[0082] This configuration maximizes the length of the heat exchange tubes covering the side frame, thereby improving heat exchange efficiency.

[0083] In other examples, the front frame 1122 is provided with an inlet and an outlet, and the rear frame 1123 is provided with a connecting pipe. In this example, there are two heat exchange tubes 113, which are respectively provided on the two side frames 1121. The two ends of the connecting pipe are respectively connected to the two heat exchange tubes 113, so that water enters through the inlet side of the front frame 1122 and exits through the outlet, forming a circulating heat exchange pipe around the frame 112b.

[0084] This design ensures a large contact area between the heat exchange tubes and the side frames. The heat exchange tubes on the two side frames are connected by a connecting pipe on the rear frame, forming a heat exchange tube ring around the frame and increasing the heat exchange area.

[0085] In some specific application scenarios, the battery in this application includes a housing, which includes a base plate and a frame connected to the periphery of the base plate. The frame and the base plate define an upward-opening accommodating cavity for accommodating battery cells. Heat exchange tubes are installed on the outside of the frame to exchange heat with the battery cells inside the accommodating cavity, thereby achieving rapid cooling of the battery cells. This solves the problems of uncooled battery cells and large temperature differences between the inside and outside. Furthermore, the heat exchange tubes are located outside the housing, facilitating maintenance and replacement.

[0086] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
