DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0036] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0038] The term "and / or" in this application simply describes the relationship between related objects, indicating that three possible relationships exist. For example, G and / or H can mean: G exists alone, G and H exist at the same time, and H exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0039] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0040] The term "plurality" used in this application refers to two or more (including two).

[0041] The energy storage box of the present application can be used to place an energy storage device, which can be a battery. The battery can include multiple battery cells, which can include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc. The embodiments of the present application do not limit this. The battery cell can be cylindrical, flat, rectangular, or other shapes, etc., which are not limited in the embodiments of the present application. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft-pack battery cells, which are not limited in the embodiments of the present application.

[0042] A battery cell includes a casing, an electrode assembly, and an electrolyte. The casing is used to hold the electrode assembly and the electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode collector. The positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer. The positive electrode collector not coated with the positive electrode active material layer serves as the positive electrode tab. Taking lithium-ion batteries as an example, the material of the positive electrode collector can be aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode sheet consists of a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The negative current collector uncoated with the negative active material layer protrudes from the negative current collector coated with the negative active material layer. The negative current collector uncoated with the negative active material layer serves as the negative electrode tab. The negative current collector can be made of copper, and the negative active material can be carbon, silicon, or other materials. To ensure that high currents can pass without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together.

[0043] The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a wound structure or a laminated structure, but the embodiments of the present application are not limited thereto.

[0044] The energy storage container contains a battery compartment and an electrical compartment. The battery compartment houses an energy storage device, while the electrical compartment houses a distribution box. Each compartment is equipped with independent cooling devices. The cooling device in the battery compartment dissipates heat only for the energy storage device, while the cooling device in the battery compartment dissipates heat only for the distribution box. Because the cooling devices for the energy storage device and the distribution box are designed independently and unconnected, the energy storage container's structure becomes complex, increasing its manufacturing cost and energy consumption.

[0045] Based on the above considerations, in order to solve the technical problem that the cooling device for the energy storage device and the cooling device for the distribution box in the energy storage container are designed independently and are not related to each other, resulting in a complex structure of the energy storage container. The present application proposes an energy storage box, which includes: a box body; a distribution box and an energy storage device, both of which are arranged in the box body, and the energy storage device has a first medium flow path; a heat exchange mechanism, which includes a heat exchange device, at least part of which is arranged in the distribution box, and the heat exchange device has a second medium flow path; the heat exchange mechanism also includes a temperature control device, which is connected to the first medium flow path to form a first medium circulation flow path, and is connected to the second medium flow path to form a second medium circulation flow path, the first medium circulation flow path and the second medium circulation flow path include a heat exchange medium, and the temperature control device is used to adjust the temperature of the heat exchange medium.

[0046] In an energy storage box of this structure, the temperature control device and the heat exchange device cooperate to enable the distribution box and the energy storage device to share a heat exchange mechanism, which can simplify the structure of the energy storage box and thus reduce the manufacturing cost of the energy storage box. In addition, the heat exchange medium in the temperature control device can heat or cool the distribution box, which can reduce the energy consumption of the energy storage box.

[0047] The energy storage box 100 according to an embodiment of the present application is described below with reference to Figures 1 to 17.

[0048] As shown in Figures 1 to 17, the energy storage box 100 according to an embodiment of the present application includes: a box body 10; a distribution box 20 and an energy storage device 70, both of which are arranged in the box body 10, and the energy storage device 70 has a first medium flow path; a heat exchange mechanism, the heat exchange mechanism including a heat exchange device 40, at least a portion of the heat exchange device 40 is arranged in the distribution box 20, and the heat exchange device 40 has a second medium flow path; the heat exchange mechanism also includes a temperature control device 30, the temperature control device 30 is connected to the first medium flow path to form a first medium circulation flow path, and the temperature control device 30 is connected to the second medium flow path to form a second medium circulation flow path. The first medium circulation flow path and the second medium circulation flow path include a heat exchange medium, and the temperature control device 30 is used to adjust the temperature of the heat exchange medium.

[0049] Among them, the box body 10 can be understood as a structure having a warehouse for placing components such as the distribution box 20 and the energy storage device 70. The distribution box 20 and the energy storage device 70 are both arranged in the box body 10. As some optional embodiments of the present application, the number of energy storage devices 70 can be set to at least one. For example, the number of energy storage devices 70 can be but not limited to 3, 4, 5, 6, etc. The energy storage device 70 can be understood as a device that can store energy (such as electrical energy). As some optional embodiments of the present application, the energy storage device 70 can include a battery. As some optional embodiments of the present application, the distribution box 20 can be understood as a device for distributing electricity. For example, the distribution box 20 can be electrically connected or communicatively connected to the energy storage device 70. The distribution box 20 can be used to adjust the charge and discharge rate of each energy storage device 70. This can reasonably control the charge and discharge rate of each energy storage device 70, which is conducive to extending the service life of the energy storage device 70.

[0050] The heat exchange mechanism includes a temperature control device 30 and a heat exchange device 40. The temperature control device 30 can be disposed within the housing 10. The energy storage device 70 has a first medium flow path containing a heat exchange medium. The temperature control device 30 is in communication with the first medium flow path of the energy storage device 70, and the temperature control device 30 and the first medium flow path of the energy storage device 70 can form a first medium circulation flow path. The first medium circulation flow path contains a heat exchange medium, which can be, but is not limited to, a liquid such as oil or ethylene glycol aqueous solution. The temperature control device 30 can adjust the temperature of the heat exchange medium. For example, the temperature control device 30 can selectively heat or cool the heat exchange medium. The heated or cooled heat exchange medium can flow into the first medium flow path and exchange heat with the energy storage device 70 to thermally manage the energy storage device 70. In other words, the heat exchange medium in the first medium circulation flow path can be heated or cooled within the temperature control device 30. The heat exchange medium heated or cooled by the temperature control device 30 can then exchange heat with the energy storage device 70 to thermally manage the energy storage device 70.

[0051] As some optional embodiments of the present application, the temperature regulating device 30 and the first medium flow path of the energy storage device 70 may be connected through a pipeline.

[0052] At least a portion of the heat exchange device 40 is arranged in the distribution box 20, and the heat exchange device 40 can exchange heat with the distribution box 20. The heat exchange device 40 has a second medium flow path, and the second medium flow path contains a heat exchange medium. The temperature control device 30 is connected to the second medium flow path of the heat exchange device 40. The temperature control device 30 and the second medium flow path of the heat exchange device 40 can form a second medium circulation flow path, and the second medium circulation flow path includes a heat exchange medium.

[0053] The temperature control device 30 can selectively heat or cool the heat exchange medium. The heated or cooled heat exchange medium can flow into the second medium flow path of the heat exchange device 40 and perform heat exchange with the distribution box 20 to perform thermal management of the distribution box 20. That is, the heat exchange medium in the second medium circulation flow path can be heated or cooled in the temperature control device 30, and the heat exchange medium heated or cooled by the temperature control device 30 can perform heat exchange with the distribution box 20 to perform thermal management of the distribution box 20.

[0054] In some optional embodiments of the present application, the temperature control device 30 may be connected to the second medium flow path of the heat exchange device 40 via a pipeline. In some optional embodiments of the present application, the temperature control device 30 may be controlled to heat or cool the heat exchange medium based on, but not limited to, parameters such as the external temperature of the energy storage box 100, the temperature of the distribution box 20, and the temperature of the energy storage device 70.

[0055] This arrangement allows the temperature of the distribution box 20 and the energy storage device 70 to be adjusted by a single heat exchange mechanism, thereby reducing the number of heat exchange mechanisms required within the energy storage box 100, thereby simplifying the structure of the energy storage box 100 and reducing the manufacturing cost of the energy storage box 100. Furthermore, the heat exchange medium within the temperature control device 30 can be used not only to heat or cool the energy storage device 70 but also to heat or cool the distribution box 20, thereby reducing the energy consumption of the energy storage box 100.

[0056] As some optional embodiments of the present application, the second medium circulation flow path can be selectively turned on or off. As some optional embodiments of the present application, the conduction or disconnection of the second medium circulation flow path can be controlled by a driving pump. For example, when the driving pump is working, the second medium circulation flow path is conducted. When the driving pump is not working, the second medium circulation flow path is disconnected. The number of driving pumps can be set to one, or the number of driving pumps can also be set to multiple. As some optional embodiments of the present application, the conduction or disconnection of the second medium circulation flow path can be controlled by a valve. The valve can be, but is not limited to, a pneumatic valve, an electric valve, etc. The number of valves can be set to one, or the number of valves can also be set to multiple. Of course, the driving pump and the valve can also be set at the same time.

[0057] In addition, the flow rate of the heat exchange medium in the second medium circulation flow path can be controlled by controlling the rotation speed of the driving pump, and the flow rate of the heat exchange medium in the second medium circulation flow path can be controlled by controlling the opening of the valve.

[0058] As some optional embodiments of the present application, the setting position of the driving pump or valve is not fixed, and the specific optional setting position of the driving pump or valve is described in the following optional embodiments (it should be explained that the following description is not an exhaustive list).

[0059] As some optional embodiments of the present application, as shown in Figure 10, the temperature control device 30 can be directly connected to the first medium flow path of the energy storage device 70 to form a first medium circulation flow path. For example, the temperature control device 30 can be directly connected to the first medium flow path of the energy storage device 70 through a first pipeline 801 and a second pipeline 802 to form a first medium circulation flow path. The temperature control device 30 can have a medium inlet and a medium outlet.

For example, the temperature control device 30 can be directly connected to the second medium flow path of the heat exchange device 40 via the first connecting line 405 and the third connecting line 407 to form the second medium circulation flow path. The third connecting line 407 can be connected between the medium inlet of the temperature control device 30 and the second medium flow path, and the first connecting line 405 can be connected between the medium outlet of the temperature control device 30 and the second medium flow path.

[0062] Furthermore, the second medium flow path of the heat exchange device 40 can be directly connected to the first medium circulation flow path to be connected to the temperature control device 30 to form a second medium circulation flow path. It can be understood that in this embodiment, part of the first medium circulation flow path is constructed as part of the second medium circulation flow path.

[0063] For example, the first connecting line 405 can be connected between the second line 802 and the second medium flow path, and the third connecting line 407 can be connected between the first line 801 and the second medium flow path. A driving pump and / or a valve can be provided in the first connecting line 405 and / or the third connecting line 407. For example, the driving pump can be provided in the first connecting line 405. Specifically, the driving pump can be provided at the connection between the first connecting line 405 and the second line 802, or the driving pump can be provided at the connection between the first connecting line 405 and the second medium flow path, or the driving pump can be provided at the connection between the third connecting line 407 and the first line 801, or the driving pump can be provided at the connection between the third connecting line 407 and the second medium flow path.

For example, the driving pump can be provided on the first connecting pipeline 405, or the driving pump can be provided on the third connecting pipeline 407.

[0065] As some optional embodiments of the present application, as shown in FIG13 , a first pipeline 801 can be connected between the medium inlet of the temperature control device 30 and the outlet of the first medium flow path of the corresponding energy storage device 70, and a second pipeline 802 can be connected between the medium outlet of the temperature control device 30 and the inlet of the first medium flow path of the corresponding energy storage device 70. A first connecting pipeline 405 can be connected between the temperature control device 30 and the second medium flow path, and a third connecting pipeline 407 can be connected between the second medium flow path and the first pipeline 801. A drive pump and / or a valve can be provided in the first connecting pipeline 405 and / or the third connecting pipeline 407. For example, the drive pump can be provided on the first connecting pipeline 405, or the drive pump can be provided on the third connecting pipeline 407.

[0066] As some optional embodiments of the present application, as shown in FIG14 , a first pipeline 801 can be connected between the medium inlet of the temperature control device 30 and the outlet of the first medium flow path of the corresponding energy storage device 70, and a second pipeline 802 can be connected between the medium outlet of the temperature control device 30 and the inlet of the first medium flow path of the corresponding energy storage device 70. A first connecting pipeline 405 can be connected between the outlet of the first medium flow path and the inlet of the second medium flow path, and a third connecting pipeline 407 can be connected between the outlet of the second medium flow path and the medium inlet of the temperature control device 30.

[0067] Alternatively, as shown in FIG15 , the first pipeline 801 can be connected between the medium inlet of the temperature control device 30 and the outlet of the first medium flow path of the corresponding energy storage device 70, and the second pipeline 802 can be connected between the medium outlet of the temperature control device 30 and the inlet of the first medium flow path of the corresponding energy storage device 70. The first connecting pipeline 405 can be connected between the outlet of the first medium flow path and the inlet of the second medium flow path, and the third connecting pipeline 407 can be connected between the outlet of the second medium flow path and the first pipeline 801. This arrangement allows the heat exchange medium flowing out of the temperature control device 30 to flow sequentially into the first medium flow path of the energy storage device 70 and the second medium flow path of the heat exchange device 40, thereby utilizing the heat exchange medium flowing out of the first medium flow path of the energy storage device 70 to regulate the temperature of the distribution box 20, thereby saving energy.

[0068] In the above technical solution, the temperature control device 30 and the heat exchange device 40 cooperate to enable the distribution box 20 and the energy storage device 70 to share a common heat exchange mechanism, thereby simplifying the structure of the energy storage box 100 and reducing the manufacturing cost of the energy storage box 100. In addition, the heat exchange medium in the temperature control device 30 can heat or cool the distribution box 20, thereby reducing the energy consumption of the energy storage box 100.

[0069] According to some embodiments of the present application, as shown in FIG11 and FIG12 , the second medium flow path is connected to the first medium flow path, so that the heat exchange medium whose temperature is adjusted by the temperature adjustment device 30 flows into the second medium flow path through part of the first medium flow path.

[0070] As some optional embodiments of the present application, as shown in Figure 11, the temperature control device 30 can be directly connected to the first medium flow path of the energy storage device 70 through a first pipeline 801 and a second pipeline 802 to form a first medium circulation flow path.

[0071] Furthermore, the second medium flow path of the heat exchange device 40 can be connected to the first medium flow path, so that the heat exchange medium, whose temperature has been adjusted by the temperature control device 30, flows into the second medium flow path through a portion of the first medium flow path. For example, the first connecting line 405 can be connected between the second line 802 and the second medium flow path, and the third connecting line 407 can be connected between the first line 801 and the second medium flow path. A drive pump and / or a valve can be provided in the first connecting line 405 and / or the third connecting line 407. For example, the drive pump can be provided in the first connecting line 405.

[0106] As some optional embodiments of the present application, the second open end can be arranged close to the first heat exchange element 401, which is conducive to shortening the length of the pipeline between the first heat exchange element 401 and the second heat exchange element 404.

[0107] In the above technical solution, by arranging the second heat exchange component 404 at the second open end of the air guide channel, the setting position of the second heat exchange component 404 can be reasonably set, so that the distribution box 20 can be reliably thermally managed, which is beneficial for keeping the distribution box 20 within a suitable temperature range for a long time, and is beneficial for improving the service life of the distribution box 20.

When the second air supply member 408 is in operation, it can draw the gas in the box body 21 into the air guide channel. In an embodiment where the air guide channel is not directly connected to the outside of the box body 21, the second air supply member 408 can draw the gas in the box body 21 into the air guide channel when in operation, and the second heat exchange member 404 can exchange heat with the gas in the air guide channel to adjust the temperature of the gas in the air guide channel, thereby thermally managing the distribution box 20. In addition, the second air supply member 408 can make the gas in the box body 21 and the air guide channel flow, that is, the second air supply member 408 can play a turbulent role, so that the second heat exchange member 404 can be in contact with more gas, thereby reliably thermally managing the distribution box 20.
