[0089] The energy unit generally includes an electrode assembly. By way of example only, the electrode assembly includes a positive electrode, a negative electrode, and a separator disposed between the negative electrode and the positive electrode. During charging and discharging of the energy unit, active ions (e.g., lithium ions) are intercalated and deintercalated between the positive electrode and the negative electrode. The separator, which is disposed between the positive electrode and the negative electrode, can function to prevent short-circuiting of the positive electrode and the negative electrode while allowing the active ions to pass through.

[0090] In some embodiments, the positive electrode can be a positive electrode sheet, which can include a positive electrode current collector and a positive electrode active material disposed on at least one surface of the positive electrode current collector.

[0092] By way of example, the positive electrode current collector can be a metal foil, a conductive polymer material, a carbon material, or a composite current collector. For example, as the metal foil, a pure metal, an alloy, a surface-treated metal, including but not limited to stainless steel, copper, aluminum, nickel, nickel, titanium, or silver, etc. can be used. The composite current collector can include a polymer material base layer and a metal layer. The composite current collector can be formed by forming a metal material (aluminum, aluminum alloy, nickel, nickel alloy, titanium, titanium alloy, silver, and silver alloy, etc.) on a polymer material base material (e.g., a base material of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.).

When the separator film is a multi-layer composite film, the materials of the layers can be the same or different, and are not particularly limited. The separator can be a separate component located between the positive electrode and the negative electrode, or can be attached to the surface of the positive electrode or the negative electrode. An inorganic particle coating, an organic particle coating, or an organic / inorganic composite coating can also be applied to the surface of the separator film.

[0101] In some embodiments, the separator is a solid-state electrolyte. The solid-state electrolyte is arranged between the positive electrode and the negative electrode, and simultaneously functions as an ion transmission and a separator of the positive electrode and the negative electrode.

As an example, when the housing is a non-sealed structure, the housing serves to protect the electrode assembly, and a sealing bag can be further included between the housing and the electrode assembly, the sealing bag being configured to encapsulate the electrode assembly and the electrolyte. Specifically, the sealing bag can be a bag-shaped insulating member or an aluminum-plastic film. When the housing is a sealed structure, the housing is configured to encapsulate the electrode assembly and the electrolyte.

[0114] As an example, the energy unit can be a cylindrical energy unit, a prismatic energy unit, a pouch energy unit, or an energy unit having another shape. The prismatic energy unit can include a square-shaped housing energy unit, a blade-shaped energy unit, a polygonal prism battery (e.g., a hexagonal prism battery), or the like, without being particularly limited.

[0229] When the bin 10 comprises the first bin 310 and the second bin 410, the same bin 10 is the first bin 310 relative to the bin 10 below, and is the second bin 410 relative to the bin 10 above, that is, the bin 10 can be the first bin 310 and the second bin 410. In other words, the limiting pin 42 can be arranged at the bottom of the bin 10, and the limiting hole 411 can be arranged at the top of the bin 10.

[0230] In this way, the two adjacent bins 10 in the height direction are limited relative to each other by the cooperation of the limiting pin 42 and the limiting hole 411, and the purpose of limiting the relative movement of the two adjacent bins 10 is achieved by a simple structure.

[0231] The limiting hole 411 at the top of the second bin 410 can be an opening for hoisting the bin 10, so that the bin 10 is hoisted by the opening during the hoisting stage of the bin 10, and after the hoisting of the bin 10 is completed, the opening at the top of the bin 10 cooperates with the limiting pin 42 at the bottom of the adjacent bin 10 above to limit the two adjacent bins 10, so as to facilitate the simplification of the structure of the bin 10.

[0232] In some embodiments, referring to FIG. 3 and FIG. 8, the bottom of the first bin 310 is provided with a first limiting member 31, the first limiting member 31 is provided with a limiting slot 311, the top of the second bin 410 is provided with a second limiting member 41, the second limiting member 41 is provided with a limiting hole 411, and the two ends of the limiting pin 42 are clamped with the limiting slot 311 and the limiting hole 411 respectively.

[0234] In this embodiment, during the stacking of the bins 10 in the height direction, the limiting pin 42 cooperates with the limiting slot 311 of the upper bin 10 of the two adjacent bins 10 and cooperates with the limiting hole 411 of the lower bin 10 of the two adjacent bins 10, so that the relative movement of the two adjacent bins 10 is limited by a simple structure.

[0235] In some embodiments, at least part of the control module 30 is arranged in the bin 10.

[0236] Here, some of the storage bodies 10 can contain the control modules 30, or all of the storage bodies 10 can contain the control modules 30.

[0237] Some of the control modules 30 can be arranged in the storage bodies 10, or all of the control modules 30 can be arranged in the storage bodies 10.

[0238] In the embodiment in which some of the storage bodies 10 contain the control modules 30, the storage bodies 10 without the control modules 30 can control the energy units 2 through the control modules 30 in other storage bodies 10. For example, the energy storage device 100 includes two storage bodies 10, i.e., a first storage body 310 and a second storage body 410, wherein the first storage body 310 contains the control module 30, and the second storage body 410 contains the energy unit 2, and the control module 30 in the first storage body 310 can control the energy unit 2 in the second storage body 410.

[0239] When all of the storage bodies 10 contain the control modules 30, and a plurality of energy units 2 are arranged in the first storage body 310 and the second storage body 410, the control modules 30 in all of the storage bodies 10 can jointly act to control the plurality of energy units 2 in the first storage body 310 and the second storage body 410, or the control modules 30 in each of the storage bodies 10 can act independently, i.e., the control module 30 in the first storage body 310 controls the plurality of energy units 2 in the first storage body 310, and the control module 30 in the second storage body 410 controls the plurality of energy units 2 in the second storage body 410.

[0240] Due to the size of the energy unit 2, the energy unit 2 cannot fill the storage body 10. By arranging the control module 30 in the storage body 10, the space in the storage body 10 can be fully utilized, and the space utilization of the storage body 10 is further improved.

[0241] In addition, the control module 30 is installed together with the storage body 10, and the pipeline and circuit of the control module 30 are connected when the control module 30 is shipped, which reduces the installation workload of the pipeline and circuit of the control module 30 on site, and is conducive to reducing the installation cost.

[0242] In some embodiments, at least some of the control modules 30 are arranged outside the storage bodies 10.

[0243] That is, some of the control modules 30 can be arranged outside the storage bodies 10, some of the control modules 30 can be arranged in the storage bodies 10, or all of the control modules 30 can be arranged outside the storage bodies 10.

[0244] Here, by setting at least part of the control module 30 outside the bin body 10, the influence of the control module 30 on the energy unit 2 can be reduced to a certain extent, and the control module 30 does not occupy the space in the bin body 10. In addition, it is also beneficial to maintain and replace the control module 30.

[0245] Here, the control module 30 set outside the bin body 10 can be connected with at least one bin body 10, or the control module 30 set outside the bin body 10 is separately arranged from the bin body 10, and the two are connected through a connection line or a connection pipeline.

[0246] In some embodiments, referring to FIG. 7, the control module 30 includes at least one of a main control module 301, a power distribution module 302, a general control module 303, and a fire control module 30430.

[0247] The energy unit 2 and the main control module 301 are electrically connected. The main control module 301 and the general control module 303 are electrically connected. The main control module 301, the general control module 303, and the fire control module 30430 are electrically connected with the power distribution module 302.

[0248] The main control module 301 is used to control the input and output of high-voltage electrical energy of the energy unit 2 in the bin body 10. The general control module 303 is used to control the on-off action of the main control module 301 in the bin body 10.

[0249] The fire control module 30430 is used to control the action of the fire-fighting element when the bin body 10 temperature imbalance causes a fire, and the fire-fighting element can be a fire extinguisher, etc. The fire-fighting element can be arranged in the bin body 10.

[0250] The power distribution module 302 is used to electrically connect the main control module 301, the general control module 303, and the fire control module 30430, so as to facilitate the circuit conduction of the main control module 301, the general control module 303, and the fire control module 30430, and maintain the normal operation of the main control module 301, the general control module 303, and the fire control module 30430.

[0251] Here, in the embodiment in which the energy storage device 100 includes a plurality of control modules 30, the plurality of control modules 30 can be the same or different.

[0252] Exemplarily, each bin body 10 is provided with a control module 30, that is, the control module 30 corresponds to the bin body 10 one by one, and one control module 30 corresponds to the control of the input and output of electrical energy of the energy unit 2 in one bin body 10, so as to facilitate the electrical control of the control module 30 on the energy unit 2.

[0253] In some embodiments, referring to FIG. 3, the energy storage device 100 includes a thermal management module 20, which is used to manage the temperature of a plurality of energy units 2.

[0254] In this embodiment, by arranging the thermal management module 20, the thermal management module 20 can manage the temperature of the energy unit 2, and reduce the risk of temperature runaway of the energy unit 2.

[0255] In some embodiments, at least part of the thermal management module 20 is arranged in the bin body 10.

[0256] The thermal management module 20 can be a liquid cooling unit, an air conditioner, a ground source cooling device, or a sea liquid cooling device.

[0257] Here, part of the bin body 10 can contain the thermal management module 20, or all of the bin body 10 can contain the thermal management module 20.

[0258] In the embodiment in which part of the bin body 10 contains the thermal management module 20, the bin body 10 without the thermal management module 20 can manage the temperature of the energy unit 2 through the thermal management module 20 in other bin bodies 10.

[0259] For example, the energy storage device 100 includes two bin bodies 10, namely a first bin body 310 and a second bin body 410, wherein the first bin body 310 contains the thermal management module 20, the second bin body 410 does not contain the thermal management module 20, and the thermal management module 20 in the first bin body 310 can manage the temperature of the energy unit 2 in the first bin body 310 and the second bin body 410.

[0260] When all of the bin bodies 10 contain the thermal management module 20, and multiple energy units 2 are arranged in the first bin body 310 and the second bin body 410, the thermal management modules 20 in all of the bin bodies 10 can jointly act on the multiple energy units 2 in the first bin body 310 and the second bin body 410 to control the temperature; or the thermal management modules 20 in each bin body 10 can act independently, that is, the thermal management module 20 in the first bin body 310 controls the temperature of the multiple energy units 2 in the first bin body 310, and the thermal management module 20 in the second bin body 410 controls the temperature of the multiple energy units 2 in the second bin body 410.

[0261] Due to the size of the energy unit 2, there can be a situation that the energy unit 2 cannot fill the bin body 10. By arranging the thermal management module 20 in the bin body 10, the space in the bin body 10 can be fully utilized, and the space utilization rate of the bin body 10 is further improved.

[0262] In addition, the thermal management module 20 is installed together with the bin body 10, and the pipeline and circuit of the thermal management module 20 are connected when the product is shipped, reducing the installation workload of the pipeline and circuit of the thermal management module 20 on site, and being conducive to reducing the installation cost.

[0263] In some embodiments, at least part of the thermal management module 20 is arranged outside the bin body 10.

[0264] That is, part of the thermal management module 20 can be arranged outside the bin body 10, and part of the thermal management module 20 can be arranged inside the bin body 10. All of the thermal management module 20 can also be arranged outside the bin body 10.

[0265] Here, by arranging at least part of the thermal management module 20 outside the bin body 10, the influence of the thermal management module 20 on the energy unit 2 can be reduced to a certain extent, and the thermal management module 20 will not occupy the space inside the bin body 10. In addition, it is also beneficial to maintain and replace the thermal management module 20.

[0266] Here, the thermal management module 20 arranged outside the bin body 10 can be connected with at least one bin body 10, or the thermal management module 20 arranged outside the bin body 10 is arranged separately from the bin body 10, and the two are connected through a connection line or a connection pipeline.

[0267] Of course, part of the structure of the thermal management module 20 can also be arranged outside the bin body 10, and the other part of the structure can be arranged inside the bin body 10.

[0268] For example, the thermal management module 20 includes a heat dissipation fan, and the heat dissipation fan is arranged outside the bin body 10. For example, the thermal management module 20 includes a heat dissipation fan and a heat exchanger, and the heat dissipation fan and the heat exchanger are arranged outside the bin body 10.

[0269] In this way, it is beneficial to heat exchange between the heat dissipation fan, the heat dissipation fan and the heat exchanger and the outside world, thereby improving the heat exchange efficiency.

[0270] In some embodiments, referring to FIG. 10, the thermal management module 20 and the control module 30 are arranged outside the bin body 10.

[0271] Here, the thermal management module 20 and / or the control module 30 can be arranged inside the installation space, or can be arranged outside the installation space.

[0272] For example, the bin body 10 is internally provided with an electric box, an inlet and outlet water pipeline, a high and low voltage wire harness, a fire fighting sensor and a pipeline, wherein the bin body 10 is provided with a switching port on the end wall and externally connected, including an inlet and outlet water connection port, a high and low voltage wire harness connection port, and a fire fighting connection port. The external water cooling unit is connected with the end inlet and outlet water connection port of each bin body 10, thereby ensuring that the temperature of the internal battery monomer is maintained within a reasonable range; the external centralized control cabinet is connected with the high and low voltage connection port and the fire fighting connection port at the end, thereby realizing charging and discharging, communication control, fire fighting control and the like.

[0273] In some embodiments, the energy unit 2 is a battery monomer, and the weight of a single energy unit 2 is 5kg to 60kg.

[0274] The weight of the single energy unit 2 can be any one of 5 kg, 10 kg, 15 kg, 20 kg, 25 kg, 30 kg, 35 kg, 40 kg, 45 kg, 50 kg, 55 kg, 60 kg or any value between any two of them. As an example, the mass of the single energy unit 22 is 30 kg.

[0275] The weight of the energy unit 2 is appropriate so that a proper amount of energy units 2 can be placed in the bin body 10, and the energy density is moderate under the condition that the transportation demand is met.

[0276] In some embodiments, referring to FIG. 3, the energy storage device 100 includes an energy storage bin 100a, which includes a bin body 10 and components arranged in the bin body 10. The weight of the energy storage bin 100a is M, which is less than or equal to 45 tons.

[0277] The components arranged in the bin body 10 are, for example, energy units 2, connecting pipelines, control modules 30, or thermal management modules 20, etc.

[0278] Here, the energy storage bin 100a refers to a cabinet that can be transported and hoisted separately.

[0279] Exemplarily, the weight of the energy storage bin 100a can be any one of 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, 40 tons, 45 tons or any value between any two of them.

[0280] In the process of hoisting the energy storage bin 100a, it is convenient for the hoisting of the relevant hoisting device, and the transfer work of the energy storage bin 100a is facilitated.

[0281] In order to make a single energy storage bin 100a meet the requirements of some countries on the transportation limit, control the overall weight of the energy storage bin 100a to be within 45 tons, and make the integration of the energy storage bin 100a as high as possible to reduce the workload of on-site installation; at the same time, improve the energy per unit area and reduce the cost investment of customers.

[0282] In some embodiments, the energy storage device 100 includes an energy storage bin 100a, which includes a bin body 10 and components arranged in the bin body 10. The weight of the energy storage bin 100a is M, and the total weight of the energy units 2 in the bin body 10 is M1, (M1 / M) x 100% ≥ 60%.

[0283] Exemplarily, (M1 / M) x 100% can be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 90%, etc.

[0284] In this way, on the one hand, the weight proportion of the energy units 2 in the unit volume of the bin body 10 can be increased, and the electric quantity of the energy storage device 100 per unit volume can be increased; on the other hand, during the transportation of the energy storage device 100, more energy units 2 that contribute to the storage energy and have a high production difficulty and cannot be produced at the destination are transported, and other structures can be produced at a location close to the destination without being transported or with reduced transportation, which is beneficial to reduce the transportation cost of the assembled energy storage device 100.

[0285] In some embodiments, (M1 / M) x 100% ≥ 80%.

[0286] For example, (M1 / M) x 100% can be 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, or 90%, etc.

[0287] In this way, the transportation cost of the assembled energy storage device 100 can be further reduced.

[0288] In some embodiments, the energy storage device 100 includes an energy storage bin 100a, the energy storage bin 100a includes a bin body 10 and components arranged in the bin body 10, the weight of the energy storage bin 100a is M, the bin body 10 is provided with a plurality of battery devices 70, the battery device 70 includes a box body 71 and a plurality of energy units 2, the plurality of energy units 2 are contained in the box body 71, the total weight of the battery device 70 is M2, and 70% ≤ (M2 / M) x 100% ≤ 90%.

[0289] (M2 / M) x 100% can be 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, or any point value between any two of them.

[0290] When (M2 / M) x 100% ≥ 70%, the weight proportion of the energy units 2 in the unit volume of the bin body 10 can be increased, and the energy density of the bin body 10 can be increased; when (M2 / M) x 100% ≤ 90%, the structural strength of the bin body 10 can be maintained. Therefore, when 70% ≤ (M2 / M) x 100% ≤ 90%, the energy density of the energy storage bin 100a and the structural strength of the bin body 10 can be considered, and the practicability of the bin body 10 is stronger.

[0291] In some embodiments, the plurality of battery devices 70 can be arranged in rows and columns, the plurality of battery devices 70 in each row arranged along a length direction, the plurality of battery devices 70 in each column arranged along a height direction, each battery device 70 comprising a thermal management component 72 and a plurality of energy units 2. The storage body 10 further comprises a third connector and a plurality of fourth connectors, the third connector communicating the thermal management module 20 and each fourth connector, each fourth connector communicating the thermal management component 72 of the plurality of battery devices 70 in a column.

[0292] For example, the plurality of battery devices 70 can be arranged in 2 layers and 2 columns, 3 layers and 3 columns, 4 layers and 4 columns, 4 layers and 3 columns, etc.

[0293] It should be noted that the plurality of battery devices 70 can also be arranged in multiple rows, such as 2 rows, 3 rows, 4 rows, 5 rows, or 6 rows, and can also be arranged in multiple columns, such as 2 columns, 3 columns, 4 columns, 5 columns, or 6 columns.

[0294] In some embodiments, the volume of the storage body 10 is V, the total volume of the energy units 2 in the storage body 10 is V1, and (V1 / V) x 100% ≥ 30%.

[0295] The energy unit 2 comprises a shell, and the volume of the energy unit 2 is the volume of the shell. For example, the energy unit 2 is a square shell energy unit 2, and the product of the length, width, and height of the square shell energy unit 2 is the product of the length, width, and height of the shell.

[0296] In embodiments in which the energy unit 2 further comprises an electrode terminal, the electrode terminal is disposed on the shell and partially protrudes from the shell, the electrode terminal is electrically connected to the electrode assembly, and the portion of the electrode terminal protruding from the shell is not included in the volume of the energy unit 2.

[0297] (V1 / V) x 100% can be 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 55%, 60%, 65%, or 70%, etc.

[0298] On the one hand, the volume ratio of the energy units 2 in the storage body 10 per unit volume can be increased, and the electric quantity of the energy storage device 100 per unit volume can be increased. On the other hand, during transportation of the energy storage device 100, more energy units 2 that contribute to energy storage and are difficult to produce at the destination are transported, and other functional elements of the energy storage device 100, such as control elements, can be produced at a location close to the destination without being transported or with reduced transportation, which is conducive to reducing the transportation cost of the assembled energy storage device 100.

[0299] In some embodiments, (V1 / V) x 100% ≥ 50%.

[0300] (V1 / V) x 100% can be 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 75%, 80%, 85%, or 90%, etc.

[0301] It is further beneficial to reduce the transportation cost of the assembled energy storage device 100.

[0303] The volume of the energy unit 2 is the volume of the box body 71. For example, the box body 71 is a cuboid structure, and the volume of the energy unit 2 is equal to the product of the length, width, and height of the box body 71.

[0304] (V2 / V) x 100% can be a point value of any one of 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 75%, 80%, or a point value between any two of them.

[0305] When (V2 / V) x 100% ≥ 50%, the volume ratio of the energy unit 2 in the unit volume of the bin body 10 can be improved, and the energy density of the energy storage device 100 can be improved; when (V2 / V) x 100% ≤ 80%, the bin body 10 can have sufficient volume of structural members to maintain the structural strength of the bin body 10. Therefore, when 50% ≤ (V2 / V) x 100% ≤ 80%, the energy density of the energy storage device 100 and the structural strength of the bin body 10 can be considered, and the bin body 10 has stronger practicability.

[0309] When E / (a x b) is greater than or equal to 250KW / m 2 , the energy storage device 100 can have a larger energy density, improving the practicality of the energy storage device 100; when E / (a x b) is less than or equal to 700KW / m 2 , the risk of the mass of the bin body 10 being too large to crush other bin bodies 10 can be reduced, facilitating transportation of the bin body 10. Therefore, when 250KW / m 2 ≤ E / (a x b) ≤ 700KW / m 2 , the energy density of the energy storage device 100 and the mass of the bin body 10 are considered, improving the practicality of the energy storage device 100 and facilitating transportation of the energy storage device 100.
