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.

[0051] 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 "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.

[0052] 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. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0053] 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.

[0054] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0055] The term "multiple" in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0056] The battery cells mentioned in the embodiments of this application may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, etc., and the embodiments of this application do not limit this. The battery cells may be cylindrical, flat, rectangular, or other shapes, etc., and the embodiments of this application do not limit this. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft-pack battery cells, and the embodiments of this application do not limit this.

[0057] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may include a battery module or battery pack. A battery generally includes a battery case that encloses one or more battery cells or multiple battery modules. The battery case prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0058] 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.

[0059] 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.

[0060] In recent years, with the rapid development of the lithium-ion battery industry, battery swapping has become a hot topic in the electric ship sector and a mainstream recommended solution for ship charging. This model primarily relies on battery-swap energy storage devices. The power batteries in these devices play an irreplaceable and important role as the power source for electric ships. Batteries consist of a battery box and multiple cells housed within it. As core components of electric ships, battery-swap energy storage devices have high requirements for both safety and portability.

[0061] In typical battery-swap energy storage devices, to ensure sufficient power, multiple battery packs are typically stacked within the device's battery compartment. However, the constant charging and discharging of the battery packs generates significant heat, which can cause the temperature within the device's battery compartment to rise. The stacking of multiple battery packs exacerbates this phenomenon, severely impacting the device's performance and service life. It can even pose significant safety risks, compromising the safety of electric vessels.

[0062] Based on the above considerations, in order to solve the problems of large safety hazards and poor reliability of battery-swap energy storage devices, the inventors have designed an energy storage device after in-depth research, including: a box body, which forms a separated battery compartment, a temperature control compartment, a fire protection compartment and an electrical compartment; the battery compartment is provided with a battery system, a heat exchange device, a fire sensor and a fire execution device; the temperature control compartment is provided with a temperature control system, and the temperature control system is connected to the heat exchange device; the fire protection compartment is provided with a fire protection system, and the fire protection system is connected to the fire sensor and the fire execution device; the electrical compartment is provided with an electrical system, and the electrical system is electrically connected to the battery system.

[0063] In an energy storage device of this structure, the device's casing is configured as a separate battery compartment, temperature control compartment, fire protection compartment, and electrical compartment, so that the device integrates multiple functions such as power storage, temperature control, fire protection, and electrical control. Temperature control, fire protection, and electrical control can be performed on the battery system within the device's casing, thereby improving the safety and reliability of the device. Furthermore, the compartments are independent of each other, isolating the functional components from the electrical compartment, thereby reducing the risk of harm caused by the operation of the battery system.

[0064] The battery disclosed in the embodiments of this application can be used, but is not limited to, in electrical devices such as vehicles, ships, or aircraft. The energy storage device disclosed in this application can be used to expand the scope of application of the energy storage device and improve the safety of electrical equipment.

[0065] The present invention provides an electrical device that uses an energy storage device as a power source. The electrical device may be, but is not limited to, a battery-powered vehicle, an electric vehicle, a ship, a spacecraft, etc. Spacecraft may include airplanes, rockets, space shuttles, and spacecraft, etc.

[0066] For the convenience of description, the following embodiments are described by taking a ship as an example of an electrical device according to an embodiment of the present application.

[0067] Energy storage devices can not only serve as the operating power source of the ship, but also as the driving power source of the ship, replacing or partially replacing fuel oil or natural gas to provide driving power for the ship.

[0068] In order to meet different power usage requirements, the energy storage device may include multiple battery packs, wherein the multiple battery packs can be connected in series, in parallel, or in hybrid mode. Hybrid mode refers to a mixture of series and parallel modes.

[0069] like Figure 11 As shown, the battery includes a battery box 11 and a plurality of battery cells 12, and the battery cells 12 are used to be accommodated in the battery box 11. The battery box 11 is used to provide an assembly space for the battery cells 12, and the battery box 11 can adopt a variety of structures. In some embodiments, the battery box 11 may include a first box body 111 and a second box body 112, and the first box body 111 and the second box body 112 cover each other, and the first box body 111 and the second box body 112 jointly define an assembly space for accommodating the battery cells 12. The second box body 112 can be a hollow structure with one end open, and the first box body 111 can be a plate-like structure, and the first box body 111 covers the open side of the second box body 112, so that the first box body 111 and the second box body 112 jointly define an assembly space; the first box body 111 and the second box body 112 can also be hollow structures with one side open, and the open side of the first box body 111 covers the open side of the second box body 112. Of course, the battery box 11 formed by the first box body 111 and the second box body 112 can be in various shapes, such as a cylinder or a rectangular parallelepiped.

[0070] In a battery, multiple battery cells 12 can be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections within the multiple battery cells 12. Multiple battery cells 12 can be directly connected in series, in parallel, or in a hybrid configuration, and then the entire battery system 12 is housed within the battery case 11. Alternatively, a battery can be constructed by first connecting multiple battery cells 12 in series, in parallel, or in a hybrid configuration to form a battery module. The battery modules are then connected in series, in parallel, or in a hybrid configuration to form a single unit housed within the battery case 11.

[0071] A battery cell 12 is the smallest unit that makes up a battery. It includes a housing, a battery cell, and an electrolyte. The housing houses the cell and electrolyte. The housing includes a top cover assembly and a casing. The top cover assembly covers the opening in the casing to isolate the interior of the battery cell 12 from the outside environment.

[0072] The battery includes multiple rows of battery cells 12 arranged along a first direction X. Each row of battery cells 12 includes multiple battery cells 12 arranged along a second direction Y. The first direction X and the second direction Y are the length and width of the battery case 11, respectively, and the first direction X and the second direction Y are perpendicular to each other.

[0073] Each battery cell 12 can be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 12 can be cylindrical, flat, rectangular, or in other shapes.

[0074] According to some embodiments of the present application, Figure 1 As shown, the energy storage device 200 of the present application includes: a box body 2, which forms a separated battery compartment 21, a temperature control compartment 22, a fire compartment 23 and an electrical compartment 24, wherein the temperature control compartment 22, the fire compartment 23 and the electrical compartment 24 are functional compartments.

[0075] The box body 2 can be made of a high-strength and corrosion-resistant metal material so that the box body 2 has good sealing performance and protection level, thereby improving the safety and stability of the operation of the components inside the box body 2.

[0076] Box 2 can be a container, serving as a mounting platform for battery system 210, meeting diverse application requirements both onboard and onshore. While onboard, it connects to a DC networked power system to provide power for navigation and household use. While onshore, it can connect to a charging network for rapid charging of the box-type power supply.

[0077] For example, a 20-foot standard container can be used as a battery installation platform, and various system modules can be integrated inside the container to monitor and ensure the normal operation and safe use of the battery system 210 in the battery compartment.

[0078] The battery pack 214 in the electrical system 241 may be a lithium iron phosphate battery.

[0079] The interior of the box 2 can be divided into four separate compartments by a partition plate, and each compartment can be isolated by a sealed door or a sealed passage to reduce the risk of fire spread and heat interference; at the same time, the functional components in each functional compartment are isolated from the battery system 210, reducing the risk of harm caused by the operation of the battery system 210.

[0080] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the battery compartment 21 is provided with a battery system 210 , a heat exchange device 216 , a fire sensor 218 and a fire execution device 219 .

[0081] like Figure 2 As shown, the battery system 210 may include a high-voltage box 213 and a plurality of battery packs 214 . The battery system 210 is used to store electrical energy.

[0082] The heat exchange device 216 can be installed around the battery system 210 or on the battery system 210. The heat exchange device 216 can remove the heat generated by the battery system 210 by circulating coolant or air, so that the battery system 210 operates within a suitable temperature range and improves the operating stability of the battery system 210.

[0083] like Figure 5 As shown, the fire sensors 218 can be distributed at multiple locations of the battery compartment 21 , and the fire sensors 218 are used to monitor the fire risk in the battery compartment 21 in real time.

[0084] like Figure 5 and Figure 6 As shown, the fire execution device 219 may include a fire extinguishing sprinkler device or a gas release device. The fire execution device 219 is connected to the fire sensor 218. When the sensor detects a fire risk, the execution device is automatically triggered to extinguish the fire.

[0085] For example, Figure 4 and Figure 5 As shown, the fire protection system 230 includes a gas fire extinguishing control host 236 and an interlocking power supply box 237, the fire protection sensor 218 includes at least part of a smoke detector 2181, a temperature detector 2182 and a gas detector 2183, and the fire protection execution device 219 includes a sprinkler pipe 2191 and a nozzle 2192 connected to the gas fire extinguishing control host 236.

[0086] The gas fire extinguishing control host 236 is used to receive the fire alarm signal from the fire sensor 218 and control the fire execution device 219 to extinguish the fire according to a preset fire extinguishing strategy.

[0087] The host 2211 may be an air-cooled chiller.

[0088] The linkage power supply box 237 is used to provide a stable power supply for the gas fire extinguishing control host 236 and other fire-fighting equipment, ensuring that the fire-fighting system 230 can operate normally in an emergency.

[0089] The temperature control cabin 22 is provided with a temperature control system 221 , and the temperature control system 221 is connected to the heat exchange device 216 .

[0090] The temperature control system 221 may include a temperature sensor, a controller, and a cooling / heating device. The temperature control system 221 is connected to the heat exchange device 216 in the battery compartment 21 , and delivers a cooling medium to the battery compartment 21 via pipes or air ducts, thereby transferring and dissipating heat from the battery system 210 .

[0091] like Figure 5 As shown, the fire cabin 23 is provided with a fire protection system 230, which may include a gas fire extinguishing control host 236, an interlocking power supply box 237, a smoke detector 2181, a temperature detector 2182, a gas detector 2183, a fire alarm controller, an emergency start and stop button, an audible and visual alarm, an alarm bell, a deflation indicator light and other devices.

[0092] Fire pumps provide the pressure and flow of fire extinguishing agents, enabling them to be quickly and accurately sprayed into the fire area. Components such as fire piping and extinguishing agent tanks form a complete fire suppression system, enabling rapid response and extinguishing of fires.

[0093] The fire controller is connected to the fire sensor 218 and the fire execution device 219. The fire controller can receive the fire alarm signal from the fire sensor 218 and control the fire execution device 219 to extinguish the fire.

[0094] Firefighting system 230 operates in a dual-tank configuration with one active and one standby system. It operates in both automatic and manual control modes. Each protected area is equipped with detectors. If any detector detects an abnormal signal, an alarm sounds. If a fire occurs within battery compartment 21, emergency exhaust fan 233 stops operating, and firefighting system 230 initiates the release of fire extinguishing agent, with all discharged extinguishing agent acting entirely within battery compartment 21.

[0095] The electrical compartment 24 is provided with an electrical system 241, which may include electrical components such as a battery management system (BMS), a DC / AC converter, a circuit breaker, and a relay. The battery management system is used to monitor the status of the battery system 210, including parameters such as the voltage, current, and temperature of the battery pack 214, and to manage and control it. The DC / AC converter is used to convert the DC power provided by the battery system 210 into AC power for use by external devices. Electrical protection components such as circuit breakers and relays are used to protect the safe operation of the electrical system 241 and prevent faults such as short circuits and overloads.

[0096] like Figure 1 and Figure 2 As shown, the electrical system 241 is electrically connected to the battery system 210 , and the electrical system 241 and the battery system 210 can be electrically connected via cables and connectors to achieve transmission and control of electrical energy.

[0097] According to the energy storage device 200 provided in the embodiment of the present application, by configuring the housing 2 of the energy storage device 200 to be divided into a battery compartment 21, a temperature control compartment 22, a fire protection compartment 23, and an electrical compartment 24, the energy storage device 200 integrates multiple functions such as power storage, temperature control, fire protection, and electrical control. The battery system 210 in the housing 2 of the energy storage device 200 can be temperature-controlled, fire-fighting, and electrically controlled, thereby improving the safety and reliability of the energy storage device 200. At the same time, the compartments are independent of each other, and the functional components are isolated from the electrical compartment 24, thereby reducing the risk of harm caused by the operation of the battery system 210.

[0098] In some embodiments, as Figure 1 As shown, the battery compartment 21 is separated from other adjacent compartments (temperature control compartment 22, fire compartment 23 and electrical compartment 24) by fireproof materials. The fireproof materials have high fire resistance and heat insulation performance, and can effectively reduce the spread of fire and heat transfer from the battery compartment 21 to other compartments in the event of a fire in the battery system 210, thereby improving the safety of the adjacent compartments to the battery compartment 21.

[0099] Among them, fireproof materials can be selected from inorganic fiber materials such as rock wool, glass wool, aluminum silicate fiber, or composite materials such as intumescent fireproof coatings and fireproof boards.

[0100] For example, the battery compartment 21 may be separated from other adjacent compartments by A60-grade fireproof materials.

[0101] Adjacent compartments in the temperature control compartment 22, fire protection compartment 23, and electrical compartment 24 are separated by non-combustible materials. These materials will not burn or produce harmful gases in the event of a fire, effectively isolating adjacent compartments from the threat of fire while maintaining the structural integrity between the compartments and improving the reliability and stability of each compartment's operation.

[0102] Among them, non-combustible materials can be inorganic non-metallic materials such as metal, stone, and ceramics, or organic materials such as specially treated wood and plastic.

[0103] For example, adjacent compartments in the temperature control compartment 22 , the fire compartment 23 , and the electrical compartment 24 may be separated by A0-grade non-combustible materials, thereby effectively reducing the risk of heat diffusion caused by a failure of the battery system 210 .

[0104] In some embodiments, as Figure 4As shown, the temperature control cabin 22, the fire fighting cabin 23 and the electrical cabin 24 are arranged along the width direction of the box body 2 at one end of the length direction of the box body 2. The temperature control cabin 22, the fire fighting cabin 23 and the electrical cabin 24 are all arranged along the length direction of the box body 2 together with the battery cabin 21, which can make full use of the effective volume of the box body 2, making the connection between the temperature control cabin 22, the fire fighting cabin 23, the electrical cabin 24 and the battery cabin 21 more compact and reasonable, and at the same time improving the safety and reliability of the energy storage device 200 in the event of a fire.

[0105] Among them, the box body 2 is divided into a first part and a second part along the length direction. The first part is located at one end of the box body 2 in the length direction, and the temperature control chamber 22, the fire fighting chamber 23 and the electrical chamber 24 are arranged along the width direction of the box body 2 in the first part; the second part is located at the other end of the box body 2 in the length direction, and the battery chamber 21 is located in the second part.

[0106] For example, Figure 5 As shown, the temperature control chamber 22, the fire fighting chamber 23 and the electrical chamber 24 can be arranged in sequence along the width direction of the box body 2, thereby forming a compact and efficient layout structure.

[0107] Among them, the temperature control cabin 22, the fire fighting cabin 23 and the electrical cabin 24 can be arranged sequentially along the width direction of the box body 2 in the first part. In other words, the temperature control cabin 22, the fire fighting cabin 23 and the electrical cabin 24 are arranged sequentially along the width direction of the battery cabin 21.

[0108] In this embodiment, the temperature control cabin 22, the fire fighting cabin 23 and the electrical cabin 24 are all adjacent to the battery cabin 21. The various functional components in the temperature control cabin 22, the fire fighting cabin 23 and the electrical cabin 24 can be connected to the battery cabin 21 via a shorter path, which can reduce the length of the inlet and outlet pipes of the heat exchange device 216 and the bus cable 215, thereby improving the reliability and safety of the connection.

[0109] In some embodiments, as Figure 1 As shown, a fireproof partition plate 25 is provided between the battery compartment 21 and the temperature control compartment 22 , the fire compartment 23 and the electrical compartment 24 .

[0110] Among them, a fireproof partition panel 25 is provided between the second part where the battery compartment 21 is located and the first part where the temperature control compartment 22, the fire fighting compartment 23 and the electrical compartment 24 are located. The fireproof partition panel 25 can be made of fireproof material or non-combustible material and has a high fire resistance limit and thermal insulation performance.

[0111] The design of the fireproof partition plate 25 can effectively reduce the spread of fire and heat transfer from the battery compartment 21 to other compartments in the event of a fire in the battery system 210, thereby improving the safety of the adjacent compartments to the battery compartment 21.

[0112] like Figure 7As shown, the fireproof partition plate 25 is provided with a plurality of sealed cabin penetration parts 251, which are used to connect the battery compartment 21 with another adjacent compartment (such as the temperature control compartment 22, the fire compartment 23 or the electrical compartment 24) so ​​that cables or pipes in the battery compartment 21 and another adjacent compartment can pass through.

[0113] The sealed penetration member 251 may include at least one of a fire protection pipe penetration member, an intrinsically safe cable penetration member, a communication cable penetration member, a dehumidifier 30 water pipe penetration member, a liquid cooling pipe penetration member, and a busbar cable penetration member.

[0114] The fire protection pipe penetration member, the intrinsically safe cable penetration member, and the communication cable penetration member can be located above the dehumidifier 30 water pipe penetration member, the liquid cooling pipe penetration member, and the busbar cable penetration member along the height direction of the box body 2.

[0115] The liquid cooling pipeline penetration parts at least include return water penetration parts and outlet water penetration parts.

[0116] The sealed cabin-penetrating components 251 include a first sealed cabin-penetrating component 251 , a second sealed cabin-penetrating component 251 and a third sealed cabin-penetrating component 251 .

[0117] The first sealed through-chamber component 251 connects the battery compartment 21 and the temperature control compartment 22, and the pipeline between the temperature control system 221 and the heat exchange device 216 passes through the first sealed through-chamber component 251; the second sealed through-chamber component 251 connects the battery compartment 21 and the fire compartment 23, and the pipeline between the fire protection system 230 and the fire protection sensor 218 and the fire protection execution device 219 passes through the second sealed through-chamber component 251; the third sealed through-chamber component 251 connects the battery compartment 21 and the electrical compartment 24, and the pipeline between the electrical system 241 and the battery system 210 passes through the third sealed through-chamber component 251.

[0118] In this embodiment, the wiring harness layout between the compartments in the box body 2 meets the requirements for ship penetration, and the sealed penetration component 251 adopts the marine-grade MCT (Multi Cable Transit, marine-grade sealed penetration component 251) so that the use of penetration cables does not affect the separation requirements of the compartments of the energy storage device 200 and meets the requirements of marine devices.

[0119] The sealed cabin penetration member 251 has good sealing and fireproof performance. The sealed cabin penetration member 251 allows cables or pipes to pass from the battery compartment 21 to the adjacent temperature control compartment 22, fire compartment 23 or electrical compartment 24, while improving the sealing and fireproof isolation between the compartments.

[0120] The number and specifications of the sealing chamber penetration members 251 can be determined according to the number and diameter of cables or pipes, and the space limitations between the chambers.

[0121] In some embodiments, as Figure 1As shown, at least part of the battery compartment 21, the temperature control compartment 22, the fire compartment 23 and the electrical compartment 24 is provided with a lighting device 29, which can be a lighting device.

[0122] Exemplarily, the battery compartment 21 , the fire compartment 23 and the electrical compartment 24 are all provided with lighting devices 29 to facilitate user operation.

[0123] In some embodiments, as Figure 4 As shown, the fire fighting cabin 23 is provided with an air inlet duct 231 , and the air inlet duct 231 extends along the length direction of the box body 2 .

[0124] The air inlet duct 231 extends along the length of the housing 2 (e.g., from the front to the rear) to evenly distribute outside air throughout the battery compartment 21. One end of the air inlet duct 231 is connected to the outside world to allow fresh air to enter, while the other end of the air inlet duct 231 is connected to the battery compartment 21 through a sealed connection to ensure smooth air flow into the battery compartment 21.

[0125] like Figure 4 As shown, an air inlet damper 232 is provided on the air inlet duct 231. The air inlet damper 232 can be automatically controlled to automatically adjust opening or closing according to parameters such as temperature and smoke concentration in the battery compartment 21 to control air flow and prevent the spread of fire.

[0126] like Figure 4 As shown, the battery compartment 21 is provided with a fan 233 and an exhaust duct 234 that are connected to each other. The exhaust duct 234 is connected to the outside and is provided with an exhaust damper 235.

[0127] One or more fans 233 may be provided on the top or side of the battery compartment 21. These fans 233 are responsible for drawing fresh air from the air inlet duct 231 into the battery compartment 21 and circulating it through the gaps between the battery packs 214 to remove the heat generated by the battery packs 214.

[0128] The exhaust duct 234 is connected to the fan 233, and the exhaust duct 234 can extend along the length direction of the box body 2. The other end of the exhaust duct 234 is connected to the outside world so that the air heated by the battery compartment 21 can be smoothly discharged to the outside world through the exhaust duct 234.

[0129] like Figure 4 As shown, an exhaust damper 235 is provided on the exhaust duct 234. The exhaust damper 235 can be automatically controlled. The exhaust damper 235 can be opened or closed according to the environmental conditions in the battery compartment 21 to adjust the exhaust volume.

[0130] In some embodiments, the air inlet duct 231 and the air exhaust duct 234 are wrapped with fireproof material to improve safety. The fireproof material can be A60 ceramic wool.

[0131] The air inlet duct 231, the air inlet damper 232, the exhaust duct 234, the exhaust damper 235 and the fan 233 are combined into an emergency ventilation system. The emergency ventilation system has the following working modes:

[0132] First, under normal circumstances, the air inlet damper 232 and the air exhaust damper 235 are both in the open state, and the fan 233 is running, sucking fresh air from the air inlet duct 231 into the battery compartment 21 and exhausting it through the air exhaust duct 234. In this way, the air in the battery compartment 21 can be kept circulating, effectively dissipating heat.

[0133] Secondly, when an abnormality is detected within the battery compartment 21 (e.g., excessive temperature, increased smoke concentration, etc.), the fire protection system 230 can automatically close the air inlet damper 232 and the exhaust damper 235, cutting off the air flow path and preventing the spread of fire. Simultaneously, the fan 233 may stop or reverse to assist in extinguishing the fire, thereby enhancing the safety of the energy storage device 200.

[0134] Third, the emergency ventilation system is primarily used to promptly exhaust flammable gases generated by the battery pack 214. The emergency ventilation system is interlocked with the gas detector 2183. When the flammable gas concentration in the battery compartment 21 exceeds a first threshold, the air inlet damper 232 and the exhaust damper 235 open. Once these two dampers are fully opened, the emergency exhaust fan 233 automatically activates to exhaust the flammable gases, thereby improving the safety of the energy storage device 200.

[0135] like Figure 3 As shown, multiple battery packs 214 in the same battery rack 211 are connected to a bus cable 215 through a high-voltage box 213 , and the bus cable 215 is electrically connected to the electrical system 241 .

[0136] In this embodiment, by providing the high-voltage box 213 and the bus bar, orderly connection and efficient power transmission between the multiple battery packs 214 are achieved, thereby improving the stability of the operation of the entire battery system 210.

[0137] In some embodiments, as Figure 3 and Figure 10 As shown, the battery rack 211 includes a column 2111, which plays a supporting and fixing role in the battery rack 211, and can also be used to guide or carry other components and cables.

[0138] In some embodiments, the pillar 2111 extends along the height direction of the box body 2 , and some of the multiple storage compartments 212 are arranged along the extension direction of the pillar 2111 .

[0139] The external port on the high-voltage box 213 is electrically connected to the bus cable 215 at the bottom of the battery compartment 21 via a connecting cable to transmit power or signals so that the battery pack 214 in the battery compartment 21 can operate normally or be charged.

[0140] The connecting cables extend along the upright posts 2111 , which can provide a fixed path for the connecting cables so that the connecting cables can be neatly and orderly connected to the high-voltage box 213 and the battery compartment 21 , facilitating subsequent maintenance and overhaul.

[0141] The connecting cables are fixed to the upright posts 2111, which can reduce the loosening or damage of the connecting cables during movement or vibration, and also improve the stability and safety of the system.

[0142] In some embodiments, the plurality of columns 2111 are spaced apart and distributed along the length direction of the box body 2 .

[0143] In this embodiment, a battery rack 211 may include at least one column 2111 , multiple battery racks 211 include multiple columns 2111 , multiple battery racks 211 are arranged along the length direction of the box body 2 , and multiple columns 2111 are arranged along the length direction of the box body 2 .

[0144] like Figure 3 and Figure 10 As shown, the battery rack 211 further includes a plurality of mounting members 2112 , which are spaced apart and distributed along the height direction of the column 2111 . The mounting members 2112 can be threaded, clamped or welded to the column 2111 .

[0145] Each column 2111 may include at least one mounting member 2112. The mounting members 2112 on the same layer of two adjacent columns 2111 are arranged at the same height. The mounting members 2112 on the same layer of two adjacent columns 2111 form a storage compartment 212. The mounting members 2112 fix the high-voltage box 213 or the battery pack 214.

[0146] The mounting member 2112 may be an L-shaped connector or a guide rail member. The mounting member 2112 is disposed at the bottom of the high-voltage box 213 or the battery pack 214 . The mounting member 2112 may play a supporting and fixing role.

[0147] The mounting parts 2112 located at different layers on two adjacent columns 2111 can be set at the same height according to the high-voltage box 213 or battery pack 214 to be fixed, so as to facilitate fixing high-voltage boxes 213 or battery packs 214 of different heights and types at different heights.

[0148] The mounting parts 2112 on the same layer on multiple columns 2111 are set at the same height. The mounting parts 2112 on the same layer are set at the same height on multiple columns 2111. In other words, on the same horizontal plane of the battery rack 211, the mounting parts 2112 on all columns 2111 are at the same height, which helps to maintain the horizontal consistency and stability of the entire battery rack 211 structure.

[0149] Two mounting parts 2112 on the same layer on adjacent columns 2111 form a storage compartment 212. The storage compartment 212 on the same layer can hold high-voltage boxes 213 or battery packs 214 of the same type for easy classification and placement, reducing the difficulty of inspection and facilitating maintenance.

[0150] Two mounting members 2112 located on the same level on adjacent columns 2111 together form a storage compartment 212. This design allows battery rack 211 to not only hold batteries or equipment but also provide additional storage space for tools, spare parts, or other necessities. The formation of storage compartment 212 increases the practicality and functionality of battery rack 211.

[0151] In some embodiments, a spacer is provided at the bottom of the battery rack 211 , and the spacer is used to raise the height of the battery rack 211 to reduce the interference of the raised side beam 26 on the battery rack 211 .

[0152] The raising member can be a raising square tube.

[0153] In some embodiments, shock absorbers are provided at the bottom of the raising member and the battery rack 211 . The shock absorbers are used to reduce vibration of the battery rack 211 during the movement and lifting of the energy storage device, thereby improving the reliability of various electrical connections on the battery rack 211 .

[0154] In some embodiments, as Figure 8 As shown, the battery compartment 21 also includes a dehumidifier 30, which is installed at the top of the battery rack 211 to dehumidify the air in the battery compartment 21, improve the dryness in the battery compartment 21, and improve the reliability and safety of the electrical connection in the battery compartment 21.

[0155] In some embodiments, as Figure 8 As shown, the box body 2 includes connected side beams 26 and a bottom plate 271. The bottom plate 271 is installed on the side beams 26. The side beams 26 and the bottom plate 271 can be tightly connected by welding, bolting, etc. to form a stable overall structure.

[0156] The side beam 26 may include a longitudinal bottom beam 261 and a transverse bottom beam 262 . The transverse bottom beam 262 extends along the width direction of the box body 2 , and the longitudinal bottom beam 261 extends along the length direction of the box body 2 .

[0157] The upper surface of the bottom plate 271 is recessed relative to the upper surface of the side beam 26. In other words, the side beam 26 is designed to be elevated to increase the structural strength of the side beam 26, improve the rigidity and fatigue resistance of the box body 2, and thus extend the service life of the box body 2 in application scenarios where the energy storage device 200 is frequently lifted.

[0158] In this embodiment, the heightened design of the longitudinal beams on both sides of the bottom plate 271 along the width direction causes the upper surface of the bottom plate 271 to be recessed downward relative to the upper surface of the side beam 26, thereby making the internal installation plane of the box body 2 lower than the external plane.

[0159] In some embodiments, the longitudinal bottom beam 261 extends along the length direction of the box body 2 and is spaced apart along the width direction of the box body 2 at the ends of the bottom plate 271 along the width direction. Since the longitudinal bottom beam 261 is raised to enhance the fatigue resistance of the box body 2, the upper surface of the bottom plate 271 is recessed downward relative to the upper surface of the longitudinal bottom beam 261; the transverse bottom beam 262 extends along the width direction of the box body 2 and is connected to the two longitudinal bottom beams 261 at both ends respectively. The bottom plate 271 is arranged above the transverse bottom beam 262. The transverse bottom beam is used to limit the positions of the longitudinal bottom beams 261 at both ends to improve the structural stability of the box body 2.

[0160] In some embodiments, as Figure 8 As shown, the box body 2 further includes a fireproof separation layer 272 .

[0161] The fireproof separation layer 272 may be made of fireproof materials, and the fireproof materials may be inorganic fiber materials such as rock wool, glass wool, aluminum silicate fiber, or composite materials such as intumescent fireproof coatings and fireproof boards.

[0162] For example, the fireproof separation layer 272 may be made of A60 grade fireproof material.

[0163] The bottom plate 271 is arranged between the fireproof partition layer 272 and the transverse bottom beam 262. The upper surface of the fireproof partition layer 272 is recessed downward relative to the upper surface of the longitudinal bottom beam 261.

[0164] In this embodiment, the height of the longitudinal bottom beam 261 is higher than the sum of the heights of the bottom plate 271 and the fire-proof partition layer 272. The heightened design of the longitudinal bottom beam 261 can increase the structural strength of the side beam 26, improve the rigidity and fatigue resistance of the box body 2, and thus extend the service life of the box body 2 in application scenarios where the energy storage device 200 is frequently lifted.

[0165] The plurality of battery packs 214 arranged in the same battery rack 211 are sequentially connected in series, and the high-voltage box 213 is electrically connected to two adjacent battery packs 214 in the series connection direction.

[0166] In the same battery rack 211 , the high-voltage box 213 and the plurality of battery packs 214 are sequentially connected in series, thereby simplifying the circuit connection of the battery system 210 and improving the overall efficiency of the battery system 210 .

[0167] The high-voltage box 213 is located in the second storage compartment 212 from bottom to top, and multiple battery packs 214 are placed in other storage compartments 212 in sequence. The high-voltage box 213 and the multiple battery packs 214 are connected in series in sequence.

[0168] In this embodiment, when laying out the battery clusters in the box body 2, the high-voltage box 213 is raised, that is, the high-voltage box 213 is not set in the storage compartment 212 closest to the bottom plate 271. Compared with setting the high-voltage box 213 in the storage compartment 212 at the bottom layer, it is more convenient to maintain and inspect the high-voltage box 213.

[0169] It is understandable that because the upper surface of the bottom plate 271 is recessed relative to the upper surface of the side beam 26, at least a portion of the storage compartment 212 located at the bottom layer is located in the recessed area of ​​the bottom plate 271 relative to the side beam 26. Therefore, the opening of the bottom layer storage compartment 212 may be obscured by the upper surface of the side beam 26. Considering that the high-voltage box 213 requires more maintenance than the battery pack 214, if the high-voltage box 213 is placed in the bottom layer storage compartment 212, the upper surface of the side beam 26 will interfere with the removal of the high-voltage box 213 or the opening of the door of the high-voltage box 213 during maintenance, thereby increasing the difficulty of maintenance.

[0170] In some embodiments, as Figure 8 As shown, the height H of the side beam 26 satisfies: 150 mm ≤ H ≤ 400 mm. For example, the height H of the side beam 26 can be 150 mm, 200 mm, 350 mm or 400 mm.

[0171] In this embodiment, by raising the side beam 26, the structural strength of the side beam 26 can be increased, and the rigidity and fatigue resistance of the box body 2 can be improved, thereby extending the service life of the box body 2 in the application scenario where the energy storage device 200 is frequently lifted, so as to meet the use requirements of the battery-swap energy storage device.

[0172] In general energy storage devices, battery packs and high-voltage boxes are usually included. The battery packs and high-voltage boxes are stacked, with the high-voltage box located at the bottom, which makes maintenance inconvenient.

[0173] The energy storage device 200 provided in the embodiment of the present application can be a chargeable energy storage device or a battery-exchange energy storage device. The embodiment of the present application also provides a battery-exchange energy storage device, which includes: a box 2 and a battery pack.

[0174] The housing 2 forms a battery compartment 21 .

[0175] The battery pack is installed in the battery compartment 21 and is supported on the bottom plate 271. The battery pack includes a high-voltage box 213 and multiple battery packs 214. The high-voltage box 213 and the multiple battery packs 214 are stacked in multiple layers. The external port of the battery pack is provided on the high-voltage box 213, and at least one battery pack 214 is provided below the high-voltage box 213.

[0176] like Figure 3 and Figure 10 As shown, the battery pack further includes: one or more battery racks 211 , the battery rack 211 is provided with a plurality of storage compartments 212 , and each storage compartment 212 is used to set a high-voltage box 213 or a battery pack 214 .

[0177] The number of battery racks 211 can be flexibly expanded as needed, and multiple battery racks 211 can be arranged along the length direction and / or width direction of the box body 2.

[0178] Exemplarily, the battery racks 211 may be arranged in two columns along the width direction of the box body 2 , each column including a plurality of battery racks 211 , and the plurality of battery racks 211 extend along the length direction of the box body 2 .

[0179] Exemplarily, each battery rack 211 includes two columns of multi-layer storage compartments 212. One storage compartment 212 among the multiple storage compartments 212 of each battery rack 211 is used to place a high-voltage box 213, and the remaining storage compartments 212 are used to place multiple battery packs 214. The high-voltage box 213 and the multiple battery packs 214 can be connected in series in a clockwise or counterclockwise direction.

[0180] The battery rack 211 can extend along the height direction of the box 2, and multiple storage compartments 212 can be arranged along the height direction of the battery rack 211 to fully utilize the height space of the box 2, improve the space utilization rate of the box 2, and improve the energy density of the energy storage device 200.

[0181] The storage compartment 212 is used to install and fix the high-voltage box 213 or the battery pack 214 to improve the stability and reliability of the operation of the battery system 210.

[0182] Among them, such as Figure 3 As shown, the high-voltage box 213 is arranged in the second or higher storage compartment 212 from bottom to top. In other words, one or more battery packs 214 can be provided under the high-voltage box 213 to move the installation position of the high-voltage box 213 away from the bottom plate 271.

[0183] According to the battery-swap energy storage device provided in the embodiment of the present application, by raising the high-voltage box 213, it is easier to maintain and inspect the high-voltage box 213 than to set the high-voltage box 213 in the storage compartment 212 at the bottom layer.

[0184] In general battery-swap energy storage devices, the energy storage devices usually need to be frequently hoisted and moved. During the hoisting process, the box is prone to collision and damage. The rigidity and fatigue resistance of the box are crucial to the service life of the box.

[0185] In some embodiments, the box body 2 includes connected side beams 26 and a bottom plate 271, the bottom plate 271 is installed on the side beams 26, the height of the side beams 26 is H, satisfying: 150mm≤H≤400mm, and the upper surface of the bottom plate 271 is recessed downward relative to the upper surface of the side beams 26.

[0186] In this embodiment, by raising the side beam 26, the structural strength of the side beam 26 can be increased, and the rigidity and fatigue resistance of the box body 2 can be improved, thereby extending the service life of the box body 2 in the application scenario where the energy storage device 200 is frequently lifted, so as to meet the use requirements of the battery-swap energy storage device.

[0187] In some embodiments, a battery pack 214 is provided below the high-voltage box 213 , that is, the high-voltage box 213 is spaced apart from the bottom plate 271 of the box body 2 .

[0188] When the high-voltage box 213 and the plurality of battery packs 214 are installed in the storage compartments 212 of the battery rack 211 , the high-voltage box 213 is disposed in the storage compartments 212 on the second layer from bottom to top.

[0189] Since multiple battery packs 214 in the same battery group are connected to the bus cable 215 through the high-voltage box 213, the bus cables 215 of the multiple battery packs are electrically connected to the electrical system 241 after being arranged side by side at the bottom of the box 2. Only one battery pack 214 is provided under the high-voltage box 213. This can not only separate the high-voltage box 213 from the bottom plate 271, so that the high-voltage box 213 that controls the cluster can be maintained and repaired when the side beam 26 is raised, but also shorten the distance for the bus cable 215 of the high-voltage box 213 to reach the bottom of the box 2, reduce the wiring length, reduce the difficulty of wiring, and facilitate inspection and maintenance.

[0190] In some embodiments, the two ends of the battery pack 214 are arranged along the width direction of the box body 2, and the electrodes of the battery pack 214 and the inlet and outlet pipes of the heat exchange device 216 are respectively located at the two ends of the battery pack 214, thereby reducing the length of the inlet and outlet pipes of the heat exchange device 216 and the bus cable 215, reducing the complexity of the structure, and facilitating inspection and maintenance.

[0191] In some embodiments, multiple battery packs 214 within the same battery group are connected in series, and the high-voltage box 213 is electrically connected to two adjacent battery packs 214 in the series direction. The high-voltage box 213 and the multiple battery packs 214 are connected in series, which simplifies the circuit connection of the battery system 210 and improves the overall efficiency of the battery system 210.

[0192] The same battery pack can be located in one battery rack 211 or can be stacked and placed in the box 2 .

[0193] In some embodiments, the same battery pack includes a high-voltage box 213 and multiple battery packs 214. The high-voltage box 213 and multiple battery packs 214 in the same battery pack are arranged in two rows and multiple layers to fully utilize the height space of the box 2 to improve the energy density of the energy storage device. At the same time, the two-row setting can form an air circulation channel between adjacent columns to improve the heat dissipation effect of the high-voltage box 213 and multiple battery packs 214.

[0194] In some embodiments, as Figure 8 As shown, the lower surface of the side beam 26 is provided with a protrusion, which extends along the length direction of the box body 2. The protrusion can be a strip structure extending from one end of the length direction of the box body 2 to the other end of the length direction of the box body 2, or it can be a protrusion arranged at intervals and arranged along the length direction of the box body 2.

[0195] In this embodiment, the protrusions are used to space the box body 2 apart from the ground, so as to facilitate the hoisting of the box body 2.

[0196] In some embodiments, as Figure 8 As shown, the box body 2 also includes a side panel 273 and a water-blocking rib 274. The side panel 273 and the bottom panel 271 form a battery compartment 21 for accommodating the battery pack. The bottom end of the side panel 273 is connected to the upper surface of the side beam 26. The water-blocking rib 274 is arranged on the upper surface of the side beam 26 and is located on the outer surface of the side panel 273.

[0197] The water-blocking rib 274 is used to increase the sealing performance of the connection between the side beam 26 and the side panel 273, reduce the risk of water or other debris leaking into the box body 2 from the connection between the side beam 26 and the side panel 273, and improve the sealing performance and structural stability of the box body 2.

[0198] The water blocking ribs 274 are connected to the upper surface of the side beam 26 and the outer surface of the side plate 273 respectively. The water blocking ribs 274 can be connected to the upper surface of the side beam 26 and the outer surface of the side plate 273 by welding, threading or gluing.

[0199] In some embodiments, the water-blocking rib 274 includes a first baffle and a second baffle connected to each other, the first baffle is bent relative to the second baffle, the lower surface of the first baffle is connected to the upper surface of the edge beam 26, and the inner surface of the second baffle is connected to the outer surface of the side plate 273.

[0200] The first baffle and the second baffle may be bent relative to each other at 90 degrees, and the first baffle and the second baffle may be an integrally formed structure.

[0201] In this embodiment, by providing a water-blocking rib 274 structure in which the first baffle is bent relative to the second baffle, the waterproof performance and structural stability of the box body 2 can be improved, thereby improving the safety of the battery system 210 and reducing the difficulty and cost of installation and maintenance.

[0202] In some embodiments, as Figure 10 As shown, multiple storage compartments 212 in the same battery rack 211 are arranged in layers, and multiple storage compartments 212 are arranged layer by layer along the height direction of the battery rack 211. A battery rack 211 can have multiple columns of storage compartments 212, and multiple storage compartments 212 are distributed along the layer array. The regular arrangement can fully utilize the limited volume of the battery rack 211 and improve the energy density of the energy storage device 200.

[0203] Multiple battery packs 214 arranged on the same layer in the same battery rack 211 are arranged along the arrangement direction of the multiple battery racks 211. By placing the battery packs 214 regularly on the battery rack 211, the arrangement of the heat exchange device 216 through the temperature control circulation pipeline 217 can be facilitated, reducing the difficulty of the temperature control circulation pipeline 217.

[0204] like Figure 3 As shown, the main unit 2211 of the temperature control system 221 is connected to the heat exchange device 216 through the temperature control circulation pipeline 217. The temperature control circulation pipeline 217 includes: a first-level water supply pipe 2171, a first-level return pipe 2172, a second-level water supply pipe 2173, a second-level return pipe 2174, a tertiary water supply pipe 2175, a tertiary return pipe 2177 and a private room connecting pipe 2176.

[0205] The primary water supply pipe 2171 and the primary water return pipe 2172 both extend along the arrangement direction of the multiple battery racks 211 and are respectively arranged at the upper and lower ends of the battery racks 211 .

[0206] The first-level water supply pipe 2171 starts from the main unit 2211 of the temperature control system 221 and extends along the arrangement direction of multiple battery racks 211 (for example, from the front end to the rear end of the box 2, and from the left end to the right end of the box 2). The first-level water supply pipe 2171 is responsible for providing cooling circulating water to each battery rack 211.

[0207] The primary return pipe 2172 corresponds to the primary water supply pipe 2171 and also extends along the arrangement of the multiple battery racks 211. The primary return pipe 2172 is responsible for collecting the circulating water flowing out of each battery pack 214 and returning it to the main unit 2211 of the temperature control system 221 for further cooling.

[0208] The first-level water supply pipe 2171 and the first-level return water pipe 2172 are relatively arranged on the upper and lower sides of the battery rack 211 along the height direction. For example, the first-level water supply pipe 2171 can be arranged above the battery rack 211, and the first-level return water pipe 2172 is arranged below the battery rack 211; or, the first-level water supply pipe 2171 can be arranged below the battery rack 211, and the first-level return water pipe 2172 is arranged above the battery rack 211.

[0209] The secondary water supply pipe 2173 and the secondary water return pipe 2174 both extend vertically and are arranged on both sides of the battery rack 211 respectively.

[0210] Secondary water supply pipe 2173 branches off from primary water supply pipe 2171, extends vertically (i.e., along the height of battery rack 211), and is located on one side (e.g., the left side) of battery rack 211. Secondary water supply pipe 2173 is responsible for distributing the circulating water in primary water supply pipe 2171 to battery packs 214 on different levels within the same battery rack 211.

[0211] The secondary return pipe 2174 corresponds to the secondary water supply pipe 2173 and also extends vertically (i.e., along the height of the battery rack 211) and is located on the other side (e.g., the right side) of the battery rack 211. The secondary return pipe 2174 is responsible for collecting the circulating water flowing from the battery packs 214 on different layers within the same battery rack 211 and returning it to the primary return pipe 2172.

[0212] The tertiary water supply pipe 2175 is connected between the secondary water supply pipe 2173 and the inlet of the heat exchange device 216 corresponding to an adjacent battery pack 214 .

[0213] The tertiary water supply pipe 2175 branches off from the secondary water supply pipe 2173 and is connected to the inlet of the heat exchange device 216 corresponding to an adjacent battery pack 214. The tertiary water supply pipe 2175 enables each battery pack 214 to obtain cooling circulating water.

[0214] The inter-pack connecting pipe 2176 is arranged in the same battery rack 211 , and the heat exchange devices 216 corresponding to the multiple battery packs 214 on the same layer are connected through the inter-pack connecting pipe 2176 .

[0215] The inter-pack connecting pipe 2176 is provided between multiple battery packs 214 on the same layer within the same battery rack 211. The multiple battery packs 214 on the same layer are connected via the inter-pack connecting pipe 2176. In this way, the battery packs 214 on the same layer can share circulating water, further improving the temperature control efficiency of the temperature control system 221.

[0216] The tertiary return pipe 2177 is connected between the secondary return pipe 2174 and the outlet of the heat exchange device 216 corresponding to an adjacent battery pack 214 .

[0217] Tertiary return pipe 2177 corresponds to tertiary water supply pipe 2175 and is connected between secondary return pipe 2174 and the outlet of heat exchange device 216 corresponding to an adjacent battery pack 214. Tertiary return pipe 2177 is responsible for returning the circulating water after passing through heat exchange device 216 to secondary return pipe 2174.

[0218] In this embodiment, the design in which the main unit 2211 of the temperature control system 221 is connected to the heat exchange device 216 via the temperature control circulation pipeline 217 can improve the temperature control system 221's precise control of the temperature of each battery pack 214, so that the battery pack 214 always operates within an appropriate temperature range, thereby improving the overall performance and safety of the energy storage device 200.

[0219] The main unit 2211 of the temperature control system 221 can be placed in the temperature control cabin 22, and heat exchange with the outside world can be achieved through the heat exchange shutters on the wall of the temperature control cabin 22. The temperature control circulation pipeline 217 is connected to the battery pack 214 in the battery cabin 21 to achieve temperature regulation of the battery pack 214, so that the battery system 210 can be placed in a suitable temperature and humidity environment.

[0220] In general energy storage devices, users cannot effectively control each module in the energy storage device intuitively, nor can they understand the working conditions of the energy storage device, which needs to be improved.

[0221] In some embodiments, as Figure 9 and Figure 10 As shown, the first end face 28 of the box 2 along the length direction is provided with an interaction area 281, which can be the front or back end of the box 2 (depending on the specific design layout). The interaction area 281 is the main interface for users to interact with the internal system of the box 2.

[0222] The interactive area 281 is provided with at least part of an interactive panel 28111 , a prompt device 28112 , an operating device and an insertion port 28122 .

[0223] Interactive panel 28111 can be a display screen or touch screen, such as a 10-inch display screen. Interactive panel 28111 is used to display system status information, alarm information, operating instructions, etc., and allows users to input operations through touch or keystrokes. Interactive panel 28111 may include a graphical user interface (GUI) to enable users to intuitively understand system status and control it.

[0224] Prompt device 28112 can be an LED indicator, a buzzer, or other type of alarm. It is used to provide a visual or audible prompt to the user when a system status changes or a fault occurs. For example, when the temperature inside battery compartment 21 is too high, a red LED indicator may light up, and a buzzer may sound an alarm.

[0225] The operating devices include physical controls such as buttons, knobs, and switches that allow the user to directly operate the system. These operating devices may be used to start or stop the fan 233, open or close the damper, or reset the alarm system.

[0226] Plug-in ports 28122 are used to connect external devices, such as portable computers, data loggers, or maintenance tools. These ports may include USB ports, Ethernet ports, serial communication ports, etc. These plug-in ports 28122 allow users to easily access system data, perform system upgrades, or perform maintenance.

[0227] The interactive area 281 may have the following functions:

[0228] Information display: The interactive panel 28111 displays real-time status information of the energy storage device 200, such as the temperature of the battery compartment 21, the wind speed of the air inlet duct 231, the pressure of the exhaust duct 234, etc.

[0229] Alarm prompt: When the energy storage device 200 detects an abnormal situation, an alarm signal is sent to the user through the prompt device 28112, and detailed alarm information is displayed on the interactive panel 28111.

[0230] Operation control: allows the user to directly control the energy storage device 200 through the operating device, such as starting the fan 233 for heat dissipation, closing the damper to prevent the spread of fire, etc.

[0231] Data interaction: Data is exchanged with external devices through the plug-in interface 28122, such as exporting the energy storage device 200 log, uploading configuration files, etc.

[0232] In this embodiment, the interactive area 281 provides an intuitive and convenient user interface, allowing users to easily understand the status of the energy storage device 200, perform necessary operations, and handle abnormal situations. Furthermore, the presence of the plug-in port 28122 enhances the scalability and maintainability of the system.

[0233] The embodiment of the present application further provides an energy storage device 200, comprising:

[0234] The box body 2 forms a battery compartment 21 and an electrical compartment 24. The battery compartment 21 is provided with a battery system 210, and the electrical compartment 24 is provided with an electrical system 241 electrically connected to the battery system 210; the first end face 28 of the box body 2 along the length direction is provided with an interaction area 281, and the interaction area 281 is provided with at least part of an interaction panel 28111, a prompt device 28112, an operating device and an insertion port 28122.

[0235] The battery system 210 may include a high-voltage box 213 and a plurality of battery packs 214 . The battery system 210 is used to store electrical energy.

[0236] The electrical system 241 may include electrical components such as a battery management system (BMS), a DC / AC converter, circuit breakers, and relays. The battery management system is used to monitor the status of the battery system 210, including parameters such as the voltage, current, and temperature of the battery pack 214, and to manage and control them. The DC / AC converter is used to convert the DC power provided by the battery system 210 into AC power for use by external devices. Electrical protection components such as circuit breakers and relays are used to ensure the safe operation of the electrical system 241 and prevent faults such as short circuits and overloads.

[0237] The electrical system 241 is electrically connected to the battery system 210 . The electrical system 241 and the battery system 210 may be electrically connected via cables and connectors to achieve transmission and control of electrical energy.

[0238] According to the energy storage device 200 provided in this embodiment, by configuring the housing 2 of the energy storage device 200 to be divided into a battery compartment 21 and an electrical compartment 24, the battery system 210 within the housing 2 of the energy storage device 200 can be electrically controlled. By configuring the interactive area 281, an intuitive and convenient operation interface is provided for the user, enabling them to easily understand the status of the energy storage device 200, perform necessary operations, and handle abnormal situations. At the same time, the presence of the plug interface 28122 also enhances the scalability and maintainability of the system.

[0239] In some embodiments, the electrical compartment 24 and the battery compartment 21 are arranged along the length of the housing 2, with the electrical compartment 24 located on one side (e.g., the front or rear end) of the battery compartment 21. The electrical compartment 24 and the battery compartment 21 are separated by a partition or other structure inside the housing 2. This layout helps optimize the space utilization of the housing 2 while improving the electrical isolation and operational safety between the electrical system 241 and the battery system 210.

[0240] like Figure 9 and Figure 10 As shown, first end surface 28 is the end surface close to electrical compartment 24, and interactive area 281 faces electrical compartment 24. This allows users to interact with electrical system 241 from a position close to the electrical system 241. This helps users more conveniently access status information of electrical system 241, perform necessary operations, and handle abnormal situations. It also facilitates maintenance and repair of electrical system 241.

[0241] In some embodiments, the interactive area 281 is provided on the front side of the first end surface 28. The front side of the first end surface 28 is located in a position where the user can directly see and touch the interactive area 281 when facing the box 2, so that the user can access and operate the interactive area 281 at different heights, thereby improving the comfort and flexibility of use.

[0242] The interactive area 281 extends upward from the bottom, covering part or all of the front area of ​​the first end surface 28. This design allows users to access the interactive panel 28111, prompt device 28112, operating device and plug-in port 28122 at different heights, thereby improving the flexibility and convenience of interaction.

[0243] like Figure 9 and Figure 10 As shown, in some embodiments, the interactive panel 28111 , the prompt device 28112 , the operating device and the plug-in port 28122 do not protrude from the first end surface 28 .

[0244] In this embodiment, all or part of the interactive panel 28111, the prompt device 28112, the operating device and the plug interface 28122 can be flush with the first end surface 28, or all or part of the interactive panel 28111, the prompt device 28112, the operating device and the plug interface 28122 can be recessed inward relative to the first end surface 28. This not only makes the overall appearance of the energy storage device 200 more concise and beautiful, but also reduces the risk of accidental collision or damage caused by protruding components during the placement or lifting process of the energy storage device 200, thereby improving the safety of the lifting process.

[0245] In some embodiments, as Figure 9 and Figure 10 As shown, the interaction area 281 includes a first area 2811 and a second area 2812 arranged from top to bottom.

[0246] The first area 2811 is provided with an interactive panel 28111, a prompt device 28112 and a part of the operating device; the first area 2811 is set to be located at the top or above the interactive area 281, so that the user can find the required operating interface and information display area more quickly, thereby improving the user's usage efficiency and satisfaction.

[0247] The second area 2812 is located at the bottom or below the interactive area 281. The second area 2812 is provided with a portion of operating devices and plug-in interfaces 28122, which conform to the operating habits of the crew and improve operability.

[0248] In this embodiment, this partition design makes the functional layout of the interactive area 281 clearer and more reasonable, helping users to find the required operation interface and information display area more quickly.

[0249] In some embodiments, as Figure 9 and Figure 10 As shown, the interactive area 281 includes a first area 2811 and a second area 2812 arranged from top to bottom; the second area 2812 is provided with a part of operating devices and an insertion port 28122, which conforms to the operating habits of the crew and improves operability.

[0250] In some embodiments, as Figure 9 and Figure 10 As shown, the interactive area 281 includes a first area 2811 and a second area 2812 arranged from top to bottom. The first area 2811 is provided with an interactive panel 28111, a prompt device 28112, and a portion of the operating device. Positioning the first area 2811 at or above the interactive area 281 facilitates users to more quickly locate the desired operating interface and information display area, thereby improving user efficiency and satisfaction.

[0251] In some embodiments, as Figure 9 and Figure 10 As shown, the first area 2811 is provided with a maintenance window 282 that is openably connected to the box body 2 , and the maintenance window 282 can be pivotally connected to the box body 2 .

[0252] In this embodiment, the first area 2811 is designed as a retractable maintenance window 282. The maintenance window 282 can be opened or closed relative to the housing 2 to facilitate user maintenance, repair, or replacement of components in the interactive area 281. The maintenance window 282 can be sealed to the housing 2 to improve the sealing and safety of the housing 2 when the maintenance window 282 is closed.

[0253] The interactive panel 28111, the prompt device 28112, and the operating device on the first area 2811 are all installed in the maintenance window 282. When the maintenance window 282 is open, the user can easily access these components and perform necessary maintenance or repair work. When the maintenance window 282 is closed, the interactive panel 28111 can still be displayed and operated normally.

[0254] In some embodiments, as Figure 9 and Figure 10 As shown, the plug interface 28122 includes an AC input interface 281221, a communication output interface 281222 and multiple DC input / output interfaces 281223. The AC input interface 281221 and the communication output interface 281222 are arranged above the multiple DC input / output interfaces 281223, which helps users to more clearly identify different types of interfaces and facilitate connection operations.

[0255] The communication output interface 281222 is a heavy-duty connector socket for the energy storage device 200 to transmit communication signals at the ship end or the shore end.

[0256] The AC input interface 281221 is an input connector socket for introducing AC voltage from the outside to start or stop the energy storage device 200 in an emergency situation.

[0257] The DC input / output interface 281223 is a connector socket for charging and discharging between the energy storage device 200 and the ship end or the energy storage device 200 and the shore end.

[0258] The operating device provided in the first area 2811 includes an interface communication switch 28113 .

[0259] A prompt device 28112 for indicating the working status of each cabin is provided above the interactive panel 28111.

[0260] An interface communication switch 28113 for controlling the communication connection status between the AC input interface 281221 and the DC input / output interface 281223 is provided below the interactive panel 28111 .

[0261] The operating device provided in the second area 2812 includes a control box 281211 and an emergency fire extinguishing operating element 281212. The control box 281211 and the emergency fire extinguishing operating element 281212 are located above the plug interface 28122 of the second area 2812, so as to facilitate users to perform quick and accurate operations.

[0262] The control box 281211 has a built-in start / stop button, a local / remote switching knob and a system emergency stop button for the energy storage device 200, so as to reduce the risk of accidental collision or damage to the energy storage device 200 during placement or lifting, and improve the protection of the control buttons inside the control box 281211.

[0263] The emergency fire extinguishing operating element 281212 may be a manual button, which can be used to manually start / stop the fire fighting system 230 in an emergency.

[0264] In this embodiment, a more intuitive, easy-to-use, and feature-rich interactive interface for the energy storage device 200 is provided. This design not only improves user efficiency and satisfaction, but also further enhances the overall performance and reliability of the energy storage device 200.

[0265] In some embodiments, as Figure 9 and Figure 10 As shown, the plug interface 28122 includes an AC input interface 281221 and a DC input / output interface 281223 .

[0266] Exemplarily, six DC input / output interfaces 281223 are provided on the outside of the box-type power supply, and these interfaces use standard DC charge / discharge connectors.

[0267] The DC input / output interface 281223 can use a standard DC charge / discharge connector, which is conducive to promoting standardization work in the ship electrification industry.

[0268] In some embodiments, the DC input / output interface 281223 can be placed in an area 0.3m to 1m away from the bottom of the box 2 . For example, the DC input / output interface 281223 can be placed about 0.6m away from the bottom of the box 2 .

[0269] In this embodiment, considering that the crew needs to drag the plug of the DC connector and the rear-end connecting cable when connecting the DC connector, in order to improve the power replacement efficiency and the operability of installing the connector, the DC input / output interface 281223 is placed at a position about 0.6m away from the bottom of the box 2. This height makes it easier for the crew to complete the connection between the box power supply and the hull power supply end when the hull is shaking.

[0270] In some embodiments, as Figure 9 and Figure 10 As shown, the interface communication switches 28113 include multiple ones, and the multiple interface communication switches 28113 are arranged at different positions of the interaction area 281 to meet different connection requirements.

[0271] A portion of the interface communication switches 28113 corresponds one-to-one to the plug interfaces 28122. The communication switches can individually control the communication connection status of each plug interface 28122. Users can turn on or off the communication function of a specific plug interface 28122 as needed to meet the requirements of different application scenarios.

[0272] A portion of the interface communication switches 28113 is used to control the communication connection status of multiple plug-in interfaces 28122 to simplify the user's operation process and improve operation efficiency.

[0273] In this embodiment, the tail ends of the communication output interface 281222, the AC input interface 281221 and the DC input / output interface 281223 can be directly connected to the junction box in the electrical compartment 24, thereby reducing the length of the communication cables and DC cables and reducing the production cost.

[0274] For example, a lithium iron phosphate battery system 210 can be integrated in the battery compartment 21. The lithium iron phosphate battery system 210 is divided into 8 battery cabinets. Each battery cabinet contains 15 battery packs 214 and 1 high-voltage box 213. The 15 battery packs 214 are placed in a storage compartment 212 of the battery rack 211 in a certain order. The high-voltage box 213 collects the capacity of the 15 battery packs 214 and is placed on the second layer at the bottom of the battery rack 211 to facilitate maintenance and inspection of the high-voltage box 213. At the same time, the high-voltage boxes 213 of each cluster are output in parallel to the junction cabinet, and the junction cabinet uniformly transmits the power to the output and input interfaces of the box-type power supply.

[0279] In this embodiment, the electric ship is a battery-swap ship. Compared with a rechargeable ship, the electric ship of this application adopts battery-swap energy replenishment, which can greatly improve the energy replenishment efficiency of the electric ship, reduce costs, solve mileage anxiety, increase the working time of the electric ship, and thus increase profits.
