[0004] New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already widely used. In addition, batteries are being used more and more in the field of energy storage.

[0005] In related technologies, energy storage devices can be used to provide power to new energy electric vehicles. Energy storage devices include batteries, which include a power terminal for inputting and outputting electrical energy. The batteries are high-rate batteries, delivering a large current, and the power terminal occupies a significant amount of internal space within the energy storage device. Summary of the Invention

[0006] In view of this, a first aspect of the present disclosure aims to provide a battery that reduces the space occupied by the battery's charging terminals. The battery includes a housing and a power delivery assembly, the power delivery assembly being disposed on one side of the housing along a first direction, the power delivery assembly including at least two charging terminals arranged along a second direction, the first direction being perpendicular to the vertical direction, and the second direction intersecting the first direction.

[0007] In this embodiment, the battery casing provides space to accommodate individual battery cells. A power transmission group is disposed on the side of the casing along a first direction. The power transmission group includes at least two terminals, which can connect to multiple electrical wires. When the current is high, power is transmitted through these multiple electrical wires. By increasing the number of terminals in the power transmission group, the cross-sectional area of ​​a single electrical wire can be reduced, thus reducing the size occupied by a single terminal along the first direction. At least two terminals are arranged along a second direction, meaning they are arranged along the plane containing the side. This reduces the space occupied by the power transmission group in the first direction while still meeting the battery's rate and current requirements. The battery can be used in an energy storage device, which includes a cabinet providing space to accommodate the battery. By providing a fixed storage space within the cabinet, the space occupied by the terminals is reduced, allowing for a larger casing size and more space within the casing for individual battery cells. This facilitates efficient use of space within the cabinet and increases the battery's energy value.

Detailed Implementation

[0033] The embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this disclosure.

[0034] In the description of the embodiments of this disclosure, it should be noted that the terms "upper," "lower," "first direction," "second direction," "third direction," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this disclosure 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. Therefore, they should not be construed as limitations on the embodiments of this disclosure. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of the embodiments of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure based on the specific circumstances.

[0036] In the description of this specification, references to terms such as "some embodiments," "exemplary," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the embodiments of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, those skilled in the art can combine the different embodiments or examples described in this disclosure and the features of those different embodiments or examples without contradiction.

[0037] It should be noted that in the embodiments disclosed herein, "at least two" refers to a quantity of two or more, and "multiple" refers to a quantity of two or more.

[0038] In related technologies, energy storage devices include a cabinet and batteries, with the batteries located inside the cabinet. The cabinet has ample vertical space, but its horizontal dimensions are limited by the available floor space. Batteries typically have a single connection point connected to a cable for energy transmission. Higher battery rates result in greater current, requiring larger cable cross-sectional areas and thus more space occupied by the connection point. With high-rate batteries, the larger current necessitates larger cable cross-sectional areas, leading to the connection point occupying significant horizontal space within the cabinet. This reduces the usable space for the battery, resulting in a smaller battery size and less usable space for individual cells, hindering the energy storage device from delivering higher energy values.

[0039] In view of this, referring to Figures 1-4, this disclosure provides an energy storage device 1000, including a cabinet 300 and a battery 100. The cabinet 300 has a receiving space; the battery 100 is disposed within the receiving space.

[0040] The energy storage device 1000 can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. The energy storage device 1000 can store electrical energy as needed and output it when appropriate. For example, the energy storage device 1000 can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours.

[0041] For example, the energy storage device 1000 disclosed herein can be used as a charging device to provide power to electrical devices such as new energy vehicles.

[0042] For example, the energy storage device 1000 may include modules such as a thermal management module, a main control module, a central control module, a power distribution module, and a fire protection module.

[0043] For example, the thermal management module may include a liquid cooling unit that provides coolant to each battery device via piping for regulating the temperature of individual battery cells.

[0044] As an example, the main control module includes modules such as the Slave Battery Management Unit (SBMU) and the fusion switch.

[0045] As an example, the central control module can serve as the battery management unit of the energy storage device 1000, used for monitoring and managing the energy storage device 1000. The central control module can monitor information such as the current, voltage, power, state of charge, or temperature of the energy storage device 1000. For example, it can control the charging and discharging current and voltage of the energy storage device 1000. As an example, the central control module includes modules such as the Insulation Monitoring Module (IMM), the Master Battery Management Unit (MBMU), the Ethernet (ETH) module, and the fiber optic conversion module.

[0046] As an example, a fire protection system includes control panels, detectors, alarm devices, etc., used to detect, alarm, or extinguish fires in energy storage systems.

[0047] As an example, the power distribution unit can be used to distribute power to the 1000 power modules of the energy storage device.

[0048] This disclosure also provides a battery 100 that can be used in an energy storage device 1000. This battery 100 reduces the space occupied by the power connection terminals 21 and increases the energy value of the battery 100 in a fixed-volume cabinet 300. The battery 100 includes a housing 10 and a power transmission group 20. The power transmission group 20 is disposed on one side of the housing 10 along a first direction. The power transmission group 20 includes at least two power connection terminals 21 arranged along a second direction. The first direction is perpendicular to the vertical direction, and the second direction intersects the first direction.

[0049] Battery 100 includes individual battery cells. Battery 100 may include one or at least two individual battery cells.

[0050] For example, at least two battery cells in battery 100 can be connected in series, parallel, or in a hybrid configuration. A hybrid configuration means that at least two battery cells are connected in both series and parallel configurations. At least two battery cells can be directly connected in series, parallel, or in a hybrid configuration; alternatively, at least two battery cells can first be connected in series, parallel, or in a hybrid configuration to form a battery cell module, and then the at least two battery cell modules can be connected in series, parallel, or in a hybrid configuration to form a whole.

[0051] A single battery cell can be a rechargeable battery. A rechargeable battery is a battery cell that can be recharged after it has been discharged, allowing the active materials to be activated and the cell to continue to be used.

[0052] The battery cells can be lithium-ion battery cells, sodium-ion battery cells, sodium-lithium-ion battery cells, lithium metal battery cells, sodium metal battery cells, lithium-sulfur battery cells, magnesium-ion battery cells, nickel-metal hydride battery cells, nickel-cadmium battery cells, or lead-acid battery cells, etc.

[0053] A single battery cell may include a casing, an electrode assembly, and an electrolyte, with the electrode assembly and electrolyte both located within the casing. The electrode assembly includes a positive electrode, a negative electrode, and a separator, with the separator located between the positive and negative electrodes. Active ions in the electrolyte migrate between the positive and negative electrodes to achieve charging and discharging.

[0054] The battery cell can be cylindrical, prismatic, or other shapes. Prismatic battery cells include prismatic or multi-prismatic cells, such as hexagonal prismatic cells, etc., and this disclosure does not have any particular limitations.

[0055] The individual battery cells can be housed within the housing 10. The housing 10 can be a sealed housing, which is beneficial to the safety and stability of the battery 100, and provides more reliable dust and water resistance, thus making it suitable for use in harsher, more humid, or even submerged environments.

[0056] The power terminal 21 is used to connect to the electrical connection 200. The power terminal 21 is used to transmit electrical energy, for example, the battery 100 outputs electrical energy to the electrical device or the power grid inputs electrical energy to the battery 100.

[0057] In this embodiment, the housing 10 of the battery 100 provides space to accommodate individual battery cells. A power transmission group 20 is disposed on the side of the housing 10 along a first direction. The power transmission group 20 includes at least two terminals 21, which can connect to multiple electrical wires 200. When the current is high, power is transmitted through the multiple electrical wires 200. By increasing the number of terminals 21 in the power transmission group 20, the cross-sectional area of ​​a single electrical wire 200 can be reduced, and the size occupied by a single terminal 21 along the first direction can be reduced. At least two terminals 21 are arranged along a second direction, that is, the terminals 21 are arranged along the plane containing the side. Thus, while meeting the battery's 100% rate and current requirements, the space occupied by the power transmission group 20 in the first direction can be reduced. When battery 100 is used in energy storage device 1000, the space occupied by the power connection terminal 21 is reduced when the cabinet 300 provides a fixed storage space. The size of the cabinet 10 can be larger, and there can be more space inside the cabinet 10 to place individual battery cells. This is conducive to the effective utilization of the space inside the cabinet 300 and improves the energy value of battery 100.

[0058] For example, the shape of the box 10 is hexahedral, such as a cube or cuboid. For instance, with the plane perpendicular to the vertical direction as the projection plane, the projection of the box 10 is a rectangle.

[0059] Please refer to Figures 2-4. Z represents the up and down direction, X represents the first direction, and Y represents the third direction.

[0060] In some embodiments, please refer to FIG2, at least two power terminals 21 of the power transmission group 20 are arranged in a vertical direction, which is consistent with the second direction.

[0061] In this embodiment, the second direction is consistent with the vertical direction, and the power terminals 21 are arranged along the vertical direction, which facilitates installation and maintenance, makes wiring more convenient, and reduces the storage space occupied in the cabinet 300.

[0062] In some embodiments, referring to FIG2, the number of power transmission groups 20 is at least two, and the power transmission group 20 includes at least one positive electrode group and at least one negative electrode group.

[0063] The positive and negative electrode groups can serve as current transmission ports, enabling electrical connections between batteries 100 or between batteries 100 and other structures in the energy storage device 1000.

[0064] It is understood that the polarity of the terminals 21 of a single power transmission group 20 is the same. For example, if a single power transmission group 20 is a positive group, all terminals 21 of the power transmission group 20 are positive. Alternatively, if a single power transmission group 20 is a negative group, all terminals 21 of the power transmission group 20 are negative.

[0065] A single battery 100 may have two or more power delivery groups 20.

[0066] In some embodiments, the number of power delivery groups 20 is at least two, and each power delivery group 20 includes at least one positive electrode group.

[0067] In some embodiments, the number of power delivery groups 20 is at least two, and each power delivery group 20 includes at least one negative electrode group.

[0068] In some embodiments, referring to Figure 2, all power delivery groups 20 of the battery 100 are located on the same side of the housing 10.

[0069] In this embodiment, the storage space occupied by all the power transmission groups 20 in the battery 100 in the cabinet 300 can be reduced. This allows for more efficient use of the space inside the cabinet 300, increases the energy value of the battery 100, and thus increases the total energy value of the energy storage device 1000.

[0070] In some embodiments, referring to FIG2, the power delivery groups 20 of the battery 100 are arranged along a third direction, which intersects with the second direction and is perpendicular to the first direction.

[0071] In this embodiment, the power transmission group 20 is arranged along a third direction, which can reduce the possibility of interference between the power transmission groups 20, facilitate installation and maintenance, and make wiring more convenient.

[0072] In some embodiments, referring to FIG2, the energy storage device 1000 includes an electrical connection 200 having a connection segment 201 connected to a power receiving terminal 21. The connection segment 201 extends along a third direction, which intersects with a second direction and is perpendicular to a first direction.

[0073] In this embodiment, the power transmission group 20 is arranged along a third direction, which can reduce the possibility of interference when the power transmission group 200 is arranged between each power transmission group 20, and can facilitate installation and maintenance, and make the wiring more convenient.

[0074] For example, the second direction is consistent with the vertical direction, and the third direction is perpendicular to the second direction. In this way, the electrical connections 200 of each power transmission group 20 are arranged in the vertical direction, and the power transmission groups 20 are arranged in the horizontal direction along the side of the housing 10, making the overall arrangement of the electrical connections 200 in the battery 100 more concise.

[0075] In some embodiments, the sum of the outer diameters of all electrical connections 200 of a single power transmission group 20 is D1, where 29.0 mm ≤ D1 ≤ 30.2 mm. Exemplarily, D1 can be 29.0 mm, 29.1 mm, 29.2 mm, 29.3 mm, 29.4 mm, 29.5 mm, 29.6 mm, 29.7 mm, 29.8 mm, 29.9 mm, 30.0 mm, 30.1 mm, or 30.2 mm, etc.

[0076] For example, the outer diameters of the individual electrical wires 200 in a single power delivery group 20 are the same.

[0077] For example, referring to Figure 2, a single power transmission group 20 includes two electrical wires 200, the outer diameter of which is D2, 14.5mm ≤ D2 ≤ 15.1mm. For example, D2 can be 14.5mm, 14.6mm, 14.7mm, 14.8mm, 14.9mm, 15.0mm, or 15.1mm, etc. mm is a unit of length, representing millimeters.

[0078] In some embodiments, the discharge current of battery 100 is not less than 500A.

[0079] In this embodiment, a battery 100 with a discharge current of not less than 500A is a high-rate battery 100, and the charging or discharging speed of a high-rate battery 100 is faster.

[0080] It should be noted that A is the unit of electric current, ampere.

[0081] In some embodiments, at least two batteries 100 are stacked vertically to form a battery cell. The battery cell provides electrical energy to electrical devices such as new energy vehicles by discharging. The battery cell provides stable current and voltage output, ensuring the safety and efficiency of the charging process.

[0082] The number of battery cells can be one or more, for example, two, three or four, etc.

[0083] The number of batteries 100 in a single battery cell can be four, five, six, seven, or eight.

[0084] For example, the number of batteries 100 in the energy storage device 1000 can be four, five, six, seven or eight.

[0085] For example, at least two batteries 100 in the energy storage device 1000 can be connected in series, parallel, or in a hybrid configuration. A hybrid configuration means that at least two batteries 100 are connected in both series and parallel configurations. At least two batteries 100 can be directly connected in series, parallel, or in a hybrid configuration; alternatively, at least two batteries 100 can first be connected in series, parallel, or in a hybrid configuration to form a battery module, and then the at least two battery modules can be connected in series, parallel, or in a hybrid configuration to form a whole.

[0086] For example, the batteries 100 in the energy storage device 1000 are connected in series, and the positive and negative electrode groups of all batteries 100 are connected in sequence. The negative electrode group of the first battery 100 and the positive electrode group of the last battery 100 serve as external connection points of the battery cells.

[0087] For example, the individual batteries 100 are connected in parallel, the positive electrode groups of all batteries 100 are connected to each other, and the negative electrode groups of all batteries 100 are connected to each other.

[0088] In some embodiments, referring to Figure 2, the battery 100 includes a communication interface 40, and the communication interface 40 and the power delivery group 20 are disposed on the same side of the housing 10. Exemplarily, the energy storage device 1000 also includes a battery management system, and the communication interface 40 is used to connect to the battery management system of the energy storage device 1000 to transmit the status information of the battery 100. The status information of the battery 100 includes, but is not limited to, voltage, current, charging demand, real-time charging data, etc.

[0089] In this embodiment, the communication interface 40 and the power transmission group 20 are located on the same side of the housing 10 along the first direction, which can reduce the storage space of the cabinet 300 occupied by the battery 100 along the third direction.

[0090] In some embodiments, please refer to FIG2, the battery 100 includes a thermal management component 30, which includes an inlet 31 and an outlet 32. Coolant can enter the battery from the inlet 31 and flow out from the outlet 32 ​​to regulate the temperature of the battery 100.

[0091] In some embodiments, the energy storage device 1000 includes a cabinet 300 and a battery 100. The discharge current of the battery 100 is not less than 500A. The cabinet 300 has a receiving space; the battery 100 is disposed within the receiving space. The battery 100 includes a housing 10 and a power transmission group 20. The power transmission group 20 is disposed on one side of the housing 10 along a first direction. The power transmission group 20 includes two terminals 21 arranged along a second direction, which is consistent with the vertical direction, and the first direction is perpendicular to the vertical direction. There are two power transmission groups 20, one for positive terminals and one for negative terminals. All power transmission groups 20 of the battery 100 are located on the same side of the housing 10. The power transmission groups 20 of the battery 100 are arranged along a third direction. The energy storage device 1000 includes electrical connections 200. A single power transmission group 20 connects two electrical connections 200. The outer diameter of each electrical connection 200 is D1, which is 14.8 mm. Each electrical connection 200 has a connecting section 201 that connects to a power receiving terminal 21. The connecting section 201 extends along a third direction, intersecting a second direction and perpendicular to a first direction. Four batteries 100 are stacked vertically to form a battery unit.

[0092] In this embodiment, the cabinet 300 provides space for accommodating the battery 100, and the housing 10 of the battery 100 provides space for accommodating individual battery cells. A power transmission group 20 is disposed on the side of the housing 10 along a first direction. The power transmission group 20 includes at least two power terminals 21, which can connect to multiple electrical wires 200. When the current is high, power is transmitted through multiple electrical wires 200. By increasing the number of power terminals 21 in the power transmission group 20, the cross-sectional area of ​​a single electrical wire 200 can be reduced, and the size occupied by a single power terminal 21 along the first direction can be reduced. At least two power terminals 21 are arranged along a second direction, that is, the power terminals 21 are arranged along the plane containing the side. Thus, while meeting the battery's 100% rate and current requirements, the space occupied by the power transmission group 20 in the first direction can be reduced. When the cabinet 300 provides fixed storage space, reducing the space occupied by the power connection terminals 21 allows for a larger cabinet 10. This provides more space within the cabinet 10 for individual battery cells, facilitating efficient use of the cabinet 300's space and increasing the energy value of the battery 100. The vertical arrangement of the power connection terminals 21 facilitates installation and maintenance, streamlines wiring, and reduces the space occupied within the cabinet 300. The positive and negative electrode groups serve as current transmission ports, enabling electrical connections between batteries 100 or between batteries 100 and other structures within the energy storage device 1000. This also reduces the space occupied by all the power transmission groups 20 within the battery 100 within the cabinet 300. This efficient use of the cabinet 300's space increases the energy value of the battery 100, thereby increasing the overall energy value of the energy storage device 1000. The power transmission groups 20 are arranged along a third direction, which reduces the possibility of interference when arranging electrical connections 200 between the various power transmission groups 20, facilitating installation and maintenance, and making wiring more convenient. The battery unit provides power to electrical equipment such as new energy vehicles through discharge. The battery unit provides stable current and voltage output, ensuring the safety and efficiency of the charging process. The communication interface 40 and the power transmission groups 20 are located on the same side of the enclosure 10 along the first direction, which reduces the storage space occupied by the battery 100 in the cabinet 300 along the third direction.
