Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment, and in particular to an energy storage container. Background Technology

[0002] Energy storage containers are used to store battery clusters, enabling the storage and release of electrical energy. For the battery clusters to function properly, electrical equipment, fire-fighting equipment, and liquid cooling equipment are also required. The electrical equipment may include high-voltage switchgear. In related technologies, energy storage containers house battery clusters, electrical equipment, fire-fighting equipment, and liquid cooling equipment within the same storage space. This not only occupies internal space and affects the number of battery clusters the container can hold, but also causes mutual interference between the battery clusters, electrical equipment, fire-fighting equipment, and liquid cooling equipment, thus affecting the safety and stability of the equipment inside the energy storage container.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] This utility model provides an energy storage container that can solve the technical problems of limited battery cluster capacity and mutual interference between internal equipment.

[0005] Energy storage containers include:

[0006] The enclosure contains a battery compartment and an equipment compartment. The battery compartment is used to house the battery clusters. The battery compartment and the equipment compartment are distributed along the length of the enclosure.

[0007] A sealing plate is installed inside the equipment compartment. The sealing plate is used to divide the equipment compartment into a first compartment and a second compartment that are sealed and isolated from each other. The first compartment is used to accommodate at least fire-fighting equipment and liquid cooling equipment, and the second compartment is used to accommodate at least high-voltage switchgear, combiner cabinet, and distribution cabinet.

[0008] On the one hand, this invention places the equipment compartment on one side of the battery compartment along the length of the container. The high-voltage cabinet, combiner cabinet, power distribution cabinet, fire-fighting equipment, liquid cooling equipment, and other equipment inside the equipment compartment can be concentrated on the same side of the battery compartment. This arrangement allows for more space in the battery compartment, enabling the energy storage container to accommodate more batteries and achieve a higher energy density. On the other hand, the liquid cooling equipment contains coolant and has a heat dissipation channel connected to the outside. The fire-fighting equipment contains liquid extinguishing agent cylinders. This invention uses a sealing plate to divide the equipment compartment into two mutually sealed independent spaces. This arrangement prevents liquid and moisture from entering the second compartment from the first compartment, thereby improving the safety and stability of the electrical equipment in the second compartment. Furthermore, the liquid cooling equipment can directly dissipate heat from the high-voltage cabinet and combiner cabinet in the second compartment, eliminating the need for additional space for air conditioning.

[0009] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0021] This exemplary embodiment provides an energy storage container, such as Figure 1-3 As shown, Figure 1 This is a schematic diagram of the structure of an exemplary embodiment of the energy storage container disclosed herein. Figure 2 for Figure 1 The diagram shows the structure of the equipment compartment in the energy storage container. Figure 3 for Figure 1 The diagram shows a partial structural diagram of the equipment compartment inside the energy storage container.

[0022] The energy storage container includes: a container body 1 and a sealing plate 2. The container body 1 has a battery compartment 11 and an equipment compartment 12. The battery compartment 11 is used to accommodate battery clusters 9. The battery compartment 11 and the equipment compartment 12 are distributed along the length direction X of the container body 1. The sealing plate 2 is disposed in the equipment compartment 12. The sealing plate 2 is used to divide the equipment compartment 12 into a first compartment 121 and a second compartment 122 that are sealed and isolated from each other. The first compartment is used to accommodate at least fire-fighting equipment and liquid cooling equipment. The second compartment is used to accommodate at least high-voltage switchgear, combiner switchgear and distribution switchgear.

[0023] On the one hand, this exemplary embodiment places the equipment compartment on one side of the battery compartment along the length of the container. The high-voltage cabinet, combiner cabinet, distribution cabinet, fire-fighting equipment, liquid cooling equipment, and other equipment inside the equipment compartment can be concentrated on the same side of the battery compartment. This arrangement can help reserve more space for the battery compartment, so that the energy storage container can accommodate more batteries and have a higher energy density. On the other hand, the liquid cooling equipment has coolant and heat dissipation channels that are connected to the outside. The fire extinguishing agent storage cylinder in the fire-fighting equipment stores liquid. This exemplary embodiment divides the equipment compartment into two mutually sealed independent spaces by a sealing plate. This arrangement can prevent liquids, moisture, dust, etc. in the first compartment from entering the second compartment, thereby improving the safety and stability of the electrical equipment in the second compartment.

[0024] In this exemplary embodiment, as Figure 1-3 As shown, the energy storage container may further include: a wiring harness 3, the first end of which is connected to the output end of the battery cluster 9, and the second end of which is connected to the high-voltage switchgear 13; wherein, the container body 1 includes a first side 101 and a second side 101 arranged opposite to each other in its width direction Y (located in...). Figure 1 (Unmarked on the back side of the enclosure 1), the output terminal of battery cluster 9 is located on the side of the battery cluster facing the first side 101, preferably at the end of this side near the equipment compartment 12. High-voltage cabinet 13 is located on the side of combiner cabinet 14 and distribution cabinet 15 facing the first side 101. Wiring harness 3 connects the output terminal of battery cluster 9 and high-voltage cabinet 13. In this exemplary embodiment, the output terminals of high-voltage cabinet 13 and battery cluster 9 are located on the same side of the enclosure 1. This arrangement can help shorten the length of wiring harness 3 and reduce its impedance.

[0025] In this exemplary embodiment, as Figure 1-3 As shown, the energy storage container may also include a partition 16, which divides the interior of the container 1 into a battery compartment 11 and an equipment compartment 12. Wiring harnesses 3 can be connected between the output end of the battery cluster 9 and the high-voltage cabinet 13 through through-holes in the partition 16. The through-holes in the partition 16 can be sealed to ensure airtight isolation between the battery compartment 11 and the equipment compartment 12. Furthermore, the partition 16 can be an integral structure with the equipment compartment 12, or it can be an integral structure with the battery compartment 11.

[0026] In this exemplary embodiment, the fire-fighting equipment may include one or more of a gas detector, a smoke detector, an audible and visual alarm, and a fire extinguishing agent storage bottle.

[0027] A gas detector is a safety device used to detect the concentration of specific gases in the environment and issue an alarm signal, aiming to prevent accidents such as explosions, poisoning, and hypoxia caused by gas leakage. The gas detector can convert the concentration of the target gas into an electrical signal through a sensor, and after being processed by a circuit, it is compared with a preset threshold to trigger an audible and visual alarm or linkage control. A smoke detector realizes early fire warning by monitoring the smoke concentration. For example, the smoke detector can be an ionization detector or a photoelectric detector. An audible and visual alarm realizes highly penetrating warning through dual signals of sound and light. The audible and visual alarm can be used to receive alarm signals from detection devices such as gas detectors and smoke detectors to emit dual signals of sound and light. The fire extinguishing agent storage bottle stores fire extinguishing agent inside.

[0028] In this exemplary embodiment, as Figure 1-3 shown, the liquid cooling device may include: a cooling fan 8, and the air outlet of the cooling fan 8 faces the top surface of the box body 1. The liquid cooling device can circularly supply coolant to cooling devices such as a cold plate. The liquid cooling device includes an output pipeline and a return pipeline. The liquid cooling device can supply coolant to the cooling device through the output pipeline, and the coolant flowing through the cooling device flows back to the liquid cooling device through the return pipeline. A heat dissipation structure such as fins can be provided on the return pipeline, and the cooling fan 8 can blow air to the heat dissipation structure such as fins to improve the heat dissipation speed of the coolant. In this exemplary embodiment, the air outlet of the cooling fan 8 faces the top surface of the box body 1, so that the heat generated by the liquid cooling device can be quickly discharged from the energy storage container. It should be understood that in other exemplary embodiments, the cooling fan 8 can also be arranged on one side of the liquid cooling device facing the top surface and / or side surface of the box body 1. The side surface of the box body 1 refers to the side surface of the box body except the top surface and the bottom surface.

[0029] In this exemplary embodiment, as Figure 1-3 shown, the sealing plate 2 can be horizontally arranged, and the first compartment 121 is located above the second compartment 122. On the one hand, the fire-fighting equipment includes an audible and visual alarm. In this exemplary embodiment, the first compartment 121 accommodating the fire-fighting equipment is arranged at a higher position, so that it is convenient for the audible and visual alarm to attract people's attention; on the other hand, in this exemplary embodiment, the first compartment 121 accommodating the liquid cooling device is arranged at a higher position, so that it is convenient for the liquid cooling device to quickly dissipate heat through the top of the first compartment 121.

[0030] In this exemplary embodiment, as Figure 1-3As shown, the high-voltage switchgear 13, combiner cabinet 14, and distribution cabinet 15 can be arranged sequentially along the width Y direction of the enclosure 1. The high-voltage switchgear 13 is used to connect the wiring harnesses 3 of each row of battery clusters 9 in parallel. The high-voltage switchgear 13 and combiner cabinet 14 can be electrically connected via copper busbars. The combiner cabinet contains a combiner switch, which controls the opening and closing of the power transmission function of the energy storage container. Therefore, the combiner cabinet 14 can be placed next to the high-voltage switchgear 13. In other exemplary embodiments, the high-voltage switchgear and combiner cabinet can also be integrated. The combiner cabinet 14 is used to connect cables and connect to an external power system to realize the input and output of electrical energy. The distribution cabinet 15 is used to house the battery management system, indicator lights, liquid-cooled switches, lighting switches, and various AC switches. The high-voltage cabinet 13, the combiner cabinet 14, and the power distribution cabinet 15 are arranged sequentially along the width direction Y of the enclosure 1, thereby minimizing the length dimension occupied by each functional cabinet (including the high-voltage cabinet 13, the combiner cabinet 14, and the power distribution cabinet 15) in the length direction X of the enclosure 1, thus leaving more space for the battery compartment.

[0031] In this exemplary embodiment, as Figure 1-3 As shown, the energy storage container may further include: a first partition 41 and a second partition 42. The first partition 41 is disposed between the high-voltage switchgear 13 and the combiner cabinet 14; the second partition 42 is disposed between the combiner cabinet 14 and the distribution cabinet 15. Each of the spaces containing the high-voltage switchgear 13, the combiner cabinet 14, and the distribution cabinet 15 is equipped with an independent door 5, located on the side of the equipment compartment 12 opposite to the battery compartment 11. The first partition 41 and the second partition 42 can isolate the spaces containing each functional cabinet into independent spaces, thereby preventing the operation of one functional cabinet from affecting other functional cabinets. For example, normally only the independent door 5 of the space containing the combiner cabinet 14 needs to be opened to connect cables, or the independent door 5 of the space containing the distribution cabinet 15 needs to be opened for operation. The first partition 41 and the second partition 42 can be made of insulating material to prevent short circuits in the wiring of each functional cabinet; for example, the second partition 42 can be an epoxy resin board.

[0032] In this exemplary embodiment, as Figure 1-3 As shown, the thermal conductivity of the sealing plate 2 is less than or equal to 0.25 W / (m·K). For example, the thermal conductivity of the sealing plate 2 can be equal to 0.25 W / (m·K), 0.24 W / (m·K), 0.23 W / (m·K), 0.22 W / (m·K), 0.21 W / (m·K), 0.2 W / (m·K), 0.18 W / (m·K), 0.16 W / (m·K), etc. The sealing plate 2 with its low thermal conductivity can provide heat insulation and fireproofing. The sealing plate 2 can be made of polystyrene board, extruded polystyrene board, rock wool board, glass wool board, etc.

[0033] In this exemplary embodiment, as Figure 1-3As shown, a first cabinet door 61 is provided on the first compartment 121, and a sealing strip is provided on the first cabinet door 61 for sealing the first compartment 121; a second cabinet door 62 is provided on the second compartment 122, and a sealing strip is provided on the second cabinet door 62 for sealing the second compartment 122. When the first cabinet door 61 and the second cabinet door 62 are closed, the sealing strip abuts against the box body to achieve a cabinet door seal. In this exemplary embodiment, the first compartment 121 and the second compartment 122 are each provided with a cabinet door, thereby avoiding interference with other compartments when using one compartment. Figure 1-3 As shown, the multiple independent cabinet doors 5 corresponding to the second compartment 122 form the second cabinet door 62. It should be understood that in other exemplary embodiments, the second compartment 122 may also be provided with a single overall cabinet door or other numbers of cabinet doors.

[0034] In this exemplary embodiment, as Figure 1-3 As shown, the energy storage container may further include a liquid-cooled plate 7, which may be located within the battery compartment 11 and on the partition plate 16. The orthographic projection of the liquid-cooled plate 7 on the partition plate 16 at least partially overlaps with the orthographic projections of the high-voltage cabinet 13 and the combiner cabinet 14 on the partition plate 16. Liquid-cooled pipes are formed inside the liquid-cooled plate 7, which are connected to liquid-cooling equipment that can supply coolant to the liquid-cooled pipes. The high-voltage cabinet 13 and the combiner cabinet 14 are prone to generating heat, and the liquid-cooled plate 7 can cool the high-voltage cabinet 13 and the combiner cabinet 14 to prevent the heat generated by the high-voltage cabinet 13 and the combiner cabinet 14 from accumulating in the battery compartment and affecting the performance of the battery cluster. In addition, the liquid-cooled plate 7 located in the battery compartment can also dissipate heat within the battery compartment.
