Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0068] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0069] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0070] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0071] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0072] 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 are not limited to these. Battery cells may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to these shapes either. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and the embodiments of this application are not limited to these types either.

[0073] The battery mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack. A battery generally includes a battery case for encapsulating one or more battery cells or multiple battery modules. The battery case can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0074] A single battery cell includes a casing, electrode assembly, and electrolyte. The casing houses the electrode assembly and electrolyte. The electrode assembly consists of a positive electrode, a negative electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the positive and negative electrode plates. The positive electrode includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector, while the uncoated positive current collector protrudes beyond the coated one, serving as the positive electrode tab. Taking a lithium-ion battery as an example, the positive current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode includes 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, and the negative current collector without the negative active material layer protrudes from the one with the negative active material layer. The negative current collector without the negative active material layer serves as the negative electrode tab. The material of the negative current collector can be copper, and the negative active material can be carbon or silicon, etc. To ensure that a large current can be passed without melting, there are multiple positive electrode tabs stacked together, and there are multiple negative electrode tabs stacked together.

[0075] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.

[0076] In recent years, with the rapid development of the lithium battery industry, battery swapping has gradually become a hot topic in the electric ship sector, and a mainstream recommended solution for ship charging. Battery swapping primarily relies on swappable energy storage devices, whose power batteries play an irreplaceable role as the power source for electric ships. The battery consists of a battery box and multiple individual battery cells housed within it. Among these, the swappable energy storage device, as a core component of electric ships, has high requirements in terms of both safety and portability.

[0077] In typical battery-swapping energy storage devices, multiple battery packs are usually stacked within the battery compartment to provide sufficient power. However, the continuous charging and discharging of these battery packs generates significant heat, potentially causing the temperature inside the battery compartment to rise. The stacked battery pack structure exacerbates this problem, severely impacting the performance and lifespan of the energy storage device. Furthermore, it can lead to substantial safety hazards during operation, compromising the safety of electric vessels.

[0078] Based on the above considerations, in order to solve the problems of significant safety hazards and poor reliability of battery-swapping energy storage devices, the inventors, after in-depth research, designed an energy storage device, including: a housing, which forms a separated battery compartment, temperature control compartment, fire protection compartment, and electrical compartment; the battery compartment is equipped with a battery system, a heat exchange device, a fire sensor, and a fire protection actuator; the temperature control compartment is equipped with a temperature control system, which is connected to the heat exchange device; the fire protection compartment is equipped with a fire protection system, which is connected to the fire sensor and the fire protection actuator; the electrical compartment is equipped with an electrical system, which is electrically connected to the battery system.

[0079] In this type of energy storage device, the enclosure is divided into separate battery compartment, temperature control compartment, fire protection compartment, and electrical compartment. This allows the energy storage device to integrate multiple functions such as energy storage, temperature control, fire protection, and electrical control. Temperature control, fire protection, and electrical control can be performed on the battery system inside the enclosure, improving the safety and reliability of the energy storage device. At the same time, the compartments are independent of each other, isolating the functional components from the electrical compartment and reducing the risk of damage caused by the operation of the battery system.

[0080] The batteries disclosed in this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. The energy storage devices disclosed in this application can also be used, which helps to expand the applicability of the energy storage devices and improve the safety of the electrical devices.

[0081] This application provides an electrical device that uses an energy storage device as a power source. The electrical device can be, but is not limited to, electric vehicles, electric cars, ships, and spacecraft. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft.

[0082] For ease of explanation, the following embodiments will be described using a ship as an example of an electrical device according to an embodiment of this application.

[0083] Energy storage devices can not only serve as the operating power source for ships, but also as the driving power source, replacing or partially replacing fuel oil or natural gas to provide propulsion power for ships.

[0084] To meet different electricity demands, energy storage devices can include multiple battery packs, which can be connected in series, parallel, or in a hybrid configuration, where a hybrid configuration refers to a combination of series and parallel connections.

[0085] like Figure 11 As shown, the battery includes a battery case 11 and a plurality of battery cells 12, the battery cells 12 being housed within the battery case 11. The battery case 11 provides assembly space for the battery cells 12, and can employ various structures. In some embodiments, the battery case 11 may include a first case body 111 and a second case body 112, the first case body 111 and the second case body 112 overlapping each other, together defining an assembly space for accommodating the battery cells 12. The second case body 112 may be a hollow structure open at one end, and the first case body 111 may be a plate-like structure, with the first case body 111 covering the open side of the second case body 112, so that the first case body 111 and the second case body 112 together define the assembly space; alternatively, the first case body 111 and the second case body 112 may both be hollow structures open on one side, with the open side of the first case body 111 covering the open side of the second case body 112. Of course, the battery box 11 formed by the first box body 111 and the second box body 112 can be of various shapes, such as a cylinder or a cuboid.

[0086] In a battery, multiple battery cells 12 can be connected in series, parallel, or in a mixed configuration. A mixed configuration means that multiple battery cells 12 are connected in both series and parallel configurations. Multiple battery cells 12 can be directly connected in series, parallel, or in a mixed configuration, and then the entire assembly of multiple battery cells 12 is housed within a battery box 11. Alternatively, the battery can be composed of multiple battery cells 12 first connected in series, parallel, or in a mixed configuration to form a battery module, and then multiple battery modules are connected in series, parallel, or in a mixed configuration to form a whole, which is then housed within a battery box 11.

[0087] A battery cell 12 refers to the smallest unit that makes up a battery. A battery cell 12 includes a casing, a battery cell, and an electrolyte. The casing is used to house the battery cell and the electrolyte. The casing includes a top cover assembly and a housing. The top cover assembly is a component that closes onto the opening of the housing to separate the internal environment of the battery cell 12 from the external environment.

[0088] The battery includes multiple rows of battery cells 12, which are 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 direction and the width direction of the battery box 11, respectively, and the first direction X and the second direction Y are perpendicular to each other.

[0089] Each battery cell 12 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 12 can be cylindrical, flat, cuboid, or other shapes.

[0090] According to some embodiments of this application, such as Figure 1 As shown, the energy storage device 200 of this application includes: a housing 2, which forms a separated battery compartment 21, a temperature control compartment 22, a fire protection compartment 23 and an electrical compartment 24, wherein the temperature control compartment 22, the fire protection compartment 23 and the electrical compartment 24 are functional compartments.

[0091] The enclosure 2 can be made of high-strength and corrosion-resistant metal materials to give it good sealing and protection levels, thereby improving the safety and stability of the internal components.

[0092] The container 2 can be a shipping container, which serves as the installation platform for the battery system 210, meeting the application needs of various scenarios both on board and ashore. On board, it connects to a DC grid-connected power system to provide electricity for ship navigation and daily life. Ashore, it can connect to a charging network for rapid charging of the containerized power supply.

[0093] 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.

[0094] The battery pack 214 within the electrical system 241 can be a lithium iron phosphate battery.

[0095] The interior of the enclosure 2 can be divided into four compartments by partitions. 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 compartment are isolated from the battery system 210, reducing the risk of damage caused by the operation of the battery system 210.

[0096] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the battery compartment 21 is equipped with a battery system 210, a heat exchange device 216, a fire sensor 218, and a fire-fighting actuator 219.

[0097] like Figure 2 As shown, the battery system 210 may include a high-voltage box 213 and multiple battery packs 214. The battery system 210 is used to store electrical energy.

[0098] The heat exchanger 216 can be installed around or on the battery system 210. The heat exchanger 216 can remove the heat generated by the battery system 210 by circulating coolant or air, so that the battery system 210 can operate within a suitable temperature range and improve the working stability of the battery system 210.

[0099] like Figure 5 As shown, the fire sensor 218 can be distributed in multiple locations in the battery compartment 21. The fire sensor 218 is used to monitor the fire risk in the battery compartment 21 in real time.

[0100] like Figure 5 and Figure 6 As shown, the fire-fighting actuator 219 may include a fire-fighting sprinkler or a gas release device. The fire-fighting actuator 219 is connected to the fire sensor 218. When the sensor detects a fire risk, it automatically triggers the actuator to extinguish the fire.

[0101] For example, such as Figure 4 and Figure 5 As shown, the fire protection system 230 includes a gas extinguishing control host 236 and a linkage power supply box 237. The fire sensor 218 includes at least some of the smoke detector 2181, heat detector 2182 and gas detector 2183. The fire protection actuator 219 includes a sprinkler pipe 2191 and a nozzle 2192 connected to the gas extinguishing control host 236.

[0102] Among them, the gas extinguishing control host 236 is used to receive fire alarm signals from the fire sensor 218 and control the fire extinguishing execution device 219 to extinguish the fire according to the preset fire extinguishing strategy.

[0103] The main unit 2211 can be an air-cooled water chiller unit.

[0104] The linkage power supply box 237 is used to provide a stable power supply for the gas extinguishing control host 236 and other fire protection equipment, ensuring that the fire protection system 230 can work normally in an emergency.

[0105] The temperature control chamber 22 is equipped with a temperature control system 221, which is connected to the heat exchange device 216.

[0106] 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 inside the battery compartment 21, and delivers a cooling medium to the battery compartment 21 through pipes or air ducts to achieve heat transfer and dissipation of the battery system 210.

[0107] like Figure 5 As shown, the fire compartment 23 is equipped with a fire protection system 230, which may include a gas extinguishing control host 236, a linkage power supply box 237, a smoke detector 2181, a heat detector 2182, a gas detector 2183, a fire alarm controller, an emergency start / stop button, an audible and visual alarm, an alarm bell, a gas release indicator light, and other devices.

[0108] Fire pumps provide the pressure and flow rate of extinguishing agents to ensure they are rapidly and accurately delivered to the fire area. Fire piping and extinguishing agent storage tanks, along with other components, constitute a complete fire suppression system capable of responding quickly and extinguishing the fire when it occurs.

[0109] The fire controller is connected to the fire sensor 218 and the fire actuator 219. The fire controller can receive the fire alarm signal from the fire sensor 218 and control the fire actuator 219 to extinguish the fire.

[0110] The fire protection system 230 can operate in a dual-cylinder mode (one main and one backup), and its control methods include automatic and manual control modes. Each protected area is equipped with a detector, and an alarm will be sounded when any detector detects an abnormal signal. When a fire occurs in the battery compartment 21, the emergency exhaust fan 233 system will stop working, and the fire protection system 230 will start the procedure to release the extinguishing agent. All the extinguishing agent released will act on the battery compartment 21.

[0111] The electrical compartment 24 houses an electrical system 241, which may include electrical components such as a battery management system (BMS), a DC / AC converter, circuit breakers, and relays. The battery management system monitors the status of the battery system 210, including parameters such as voltage, current, and temperature of the battery pack 214, and manages and controls these parameters. The DC / AC converter converts the DC power supplied by the battery system 210 into AC power for use by external devices. Electrical protection components such as circuit breakers and relays protect the safe operation of the electrical system 241, preventing faults such as short circuits and overloads.

[0112] like Figure 1 and Figure 2 As shown, the electrical system 241 is electrically connected to the battery system 210. The electrical system 241 and the battery system 210 can be electrically connected through cables and connectors to realize the transmission and control of electrical energy.

[0113] According to the energy storage device 200 provided in the embodiments of this application, by setting the housing 2 of the energy storage device 200 as a separate battery compartment 21, temperature control compartment 22, fire protection compartment 23 and electrical compartment 24, the energy storage device 200 integrates multiple functions such as energy storage, temperature control, fire protection and electrical control. It can perform temperature control, fire protection and electrical control on the battery system 210 in the housing 2 of the energy storage device 200, thereby improving the safety and reliability of the energy storage device 200. At the same time, each compartment is independent of each other, and the functional devices are isolated from the electrical compartment 24, reducing the risk of damage caused by the operation of the battery system 210.

[0114] In some embodiments, such as Figure 1 As shown, the battery compartment 21 is separated from the adjacent compartments (temperature control compartment 22, fire compartment 23 and electrical compartment 24) by fire-resistant materials. The fire-resistant materials have a high fire resistance limit and heat insulation performance, which 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 of the battery compartment 21.

[0115] Among them, fireproof materials can be selected from inorganic fiber materials such as rock wool, glass wool, and aluminum silicate fiber, or composite materials such as intumescent fireproof coatings and fireproof boards.

[0116] For example, the battery compartment 21 may be separated from other adjacent compartments by A60 fire-resistant material.

[0117] The adjacent compartments in the temperature control compartment 22, fire protection compartment 23, and electrical compartment 24 are separated by non-combustible materials. These non-combustible materials will not burn or produce harmful gases in the event of a fire, effectively isolating the fire from the threat to adjacent compartments while maintaining the structural integrity between compartments and improving the reliability and stability of each compartment's operation.

[0118] Among them, non-flammable materials can be selected from inorganic non-metallic materials such as metals, stone, and ceramics, or organic materials such as wood and plastics that have undergone special treatment.

[0119] For example, adjacent compartments in the temperature control compartment 22, fire compartment 23 and electrical compartment 24 can be separated by A0-class non-flammable materials, which can effectively reduce the risk of heat spread caused by battery system 210 failure.

[0120] In some embodiments, such as Figure 4 As shown, the temperature control compartment 22, the fire protection compartment 23, and the electrical compartment 24 are arranged along the width direction of the enclosure 2 at one end of the length direction of the enclosure 2. The temperature control compartment 22, the fire protection compartment 23, and the electrical compartment 24 are all arranged along the length direction of the enclosure 2 with the battery compartment 21. This can make full use of the effective volume of the enclosure 2, making the connection between the temperature control compartment 22, the fire protection compartment 23, the electrical compartment 24, and the battery compartment 21 more compact and reasonable, while improving the safety and reliability of the energy storage device 200 in the event of a fire.

[0121] The enclosure 2 is divided into a first part and a second part along its length. The first part is located at one end of the length of the enclosure 2, and the temperature control compartment 22, the fire compartment 23 and the electrical compartment 24 are arranged in the first part along the width of the enclosure 2. The second part is located at the other end of the length of the enclosure 2, and the battery compartment 21 is located in the second part.

[0122] For example, such as Figure 5 As shown, the temperature control compartment 22, the fire protection compartment 23, and the electrical compartment 24 can be arranged sequentially along the width of the enclosure 2, thus forming a compact and efficient layout structure.

[0123] Among them, the temperature control compartment 22, the fire protection compartment 23 and the electrical compartment 24 can be arranged sequentially along the width direction of the first part of the enclosure 2. In other words, the temperature control compartment 22, the fire protection compartment 23 and the electrical compartment 24 are arranged sequentially along the width direction of the battery compartment 21.

[0124] In this embodiment, the temperature control compartment 22, the fire protection compartment 23, and the electrical compartment 24 are all adjacent to the battery compartment 21. Each functional device in the temperature control compartment 22, the fire protection compartment 23, and the electrical compartment 24 can be connected to the battery compartment 21 with 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, and improve the reliability and safety of the connection.

[0125] In some embodiments, such as Figure 1 As shown, a fireproof partition 25 is provided between the battery compartment 21 and the temperature control compartment 22, the fire protection compartment 23 and the electrical compartment 24.

[0126] Among them, a fireproof partition 25 is provided between the second part where the battery compartment 21 is located and the first part where the temperature control compartment 22, fire compartment 23 and electrical compartment 24 are located. The fireproof partition 25 can be made of fireproof material or non-combustible material and has a high fire resistance limit and heat insulation performance.

[0127] The fireproof partition 25 is designed to 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 adjacent compartments to the battery compartment 21.

[0128] like Figure 7 As shown, the fireproof partition 25 is provided with multiple sealed compartment components 251. The sealed compartment components 251 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 the other adjacent compartment can pass through.

[0129] The sealed passage component 251 may include at least one of the following: fire-fighting pipeline passage component, intrinsically safe cable passage component, communication cable passage component, dehumidifier 30 water pipe passage component, liquid cooling pipeline passage component, and busbar cable passage component.

[0130] Fire protection pipe penetration fittings, intrinsically safe cable penetration fittings, and communication cable penetration fittings can be located above the dehumidifier 30 water pipe penetration fittings, liquid cooling pipe penetration fittings, and busbar cable penetration fittings along the height direction of the enclosure 2.

[0131] Liquid cooling piping penetration components include at least return water penetration components and outlet water penetration components.

[0132] The sealed penetration component 251 includes a first sealed penetration component 251, a second sealed penetration component 251, and a third sealed penetration component 251.

[0133] The first sealed passageway 251 connects the battery compartment 21 and the temperature control compartment 22. The pipeline between the temperature control system 221 and the heat exchange device 216 passes through the first sealed passageway 251. The second sealed passageway 251 connects the battery compartment 21 and the fire compartment 23. The pipeline between the fire protection system 230 and the fire sensor 218 and the fire protection actuator 219 passes through the second sealed passageway 251. The third sealed passageway 251 connects the battery compartment 21 and the electrical compartment 24. The pipeline between the electrical system 241 and the battery system 210 passes through the third sealed passageway 251.

[0134] In this embodiment, the wiring harness layout between the compartments within the housing 2 meets the requirements for marine cable penetration. The sealed cable penetration component 251 is a marine-grade MCT (Multi Cable Transit) to ensure that the use of cable penetration does not affect the separation requirements of the compartments of the energy storage device 200 and meets the requirements of marine devices.

[0135] The sealed penetration component 251 has good sealing and fire resistance. The sealed penetration component 251 allows cables or pipes to pass from the battery compartment 21 into the adjacent temperature control compartment 22, fire protection compartment 23 or electrical compartment 24, while improving the sealing and fire isolation between the compartments.

[0136] The quantity and specifications of the sealed penetrating components 251 can be determined based on the quantity and diameter of cables or pipes, as well as the space constraints between compartments.

[0137] In some embodiments, such as Figure 1 As shown, at least some of the battery compartment 21, temperature control compartment 22, fire compartment 23 and electrical compartment 24 are equipped with lighting devices 29, which can be lighting lamps.

[0138] For example, the battery compartment 21, fire compartment 23 and electrical compartment 24 are all equipped with lighting devices 29 to facilitate user operation.

[0139] In some embodiments, such as Figure 4 As shown, the fire compartment 23 is provided with an air inlet duct 231, which extends along the length of the box body 2.

[0140] The air intake duct 231 extends along the length of the housing 2 (e.g., from the front end to the rear end) to ensure that outside air is evenly distributed throughout the battery compartment 21. One end of the air intake duct 231 is connected to the outside to allow fresh air to enter, while the other end of the air intake duct 231 is connected to the battery compartment 21 through a sealed connection to allow air to enter the battery compartment 21 smoothly.

[0141] 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 open or close automatically according to parameters such as temperature and smoke concentration in the battery compartment 21, so as to control airflow and prevent the spread of fire.

[0142] like Figure 4 As shown, the battery compartment 21 is equipped 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 equipped with an exhaust damper 235.

[0143] One or more fans 233 may be installed on the top or side of the battery compartment 21. These fans 233 are responsible for drawing fresh air from the air intake 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.

[0144] The exhaust duct 234 is connected to the fan 233. The exhaust duct 234 can extend along the length of the housing 2. The other end of the exhaust duct 234 is connected to the outside so that the air heated by the battery compartment 21 can be smoothly discharged to the outside through the exhaust duct 234.

[0145] like Figure 4 As shown, an exhaust damper 235 is provided on the exhaust duct 234. The exhaust damper 235 can be automatically controlled and can be opened or closed according to the environmental conditions inside the battery compartment 21 to adjust the exhaust volume.

[0146] In some embodiments, the air inlet duct 231 and the air outlet duct 234 are wrapped with fireproof material to improve safety. The fireproof material can be A60 ceramic wool.

[0147] The air inlet duct 231, air inlet damper 232, exhaust duct 234, exhaust damper 235, and fan 233 are combined to form an emergency ventilation system. The emergency ventilation system has the following operating modes:

[0148] Firstly, under normal circumstances, both the air inlet damper 232 and the air outlet damper 235 are open, and the fan 233 is running, drawing fresh air into the battery compartment 21 through the air inlet duct 231 and expelling it through the air outlet duct 234. In this way, the air inside the battery compartment 21 can be kept circulating, effectively dissipating heat.

[0149] Secondly, when an abnormality is detected inside the battery compartment 21 (such as excessively high temperature or increased smoke concentration), the fire suppression system 230 can automatically close the air intake damper 232 and the exhaust damper 235 to cut off the airflow path and prevent the fire from spreading. At the same time, the fan 233 may stop running or reverse to assist in fire suppression, thereby improving the safety of the energy storage device 200.

[0150] Thirdly, the emergency ventilation system is mainly used to promptly remove flammable gases generated by the battery pack 214. The emergency ventilation system is interlocked with the gas detector 2183. When the concentration of flammable gas in the battery compartment 21 exceeds the first threshold, the air inlet damper 232 and the air outlet damper 235 open. After the air inlet damper 232 and the air outlet damper 235 are fully open, the emergency exhaust fan 233 is automatically activated to remove the flammable gas, thereby improving the safety of the energy storage device 200.

[0151] like Figure 3 As shown, multiple battery packs 214 within the same battery rack 211 are connected to a busbar cable 215 via a high-voltage box 213, and the busbar cable 215 is electrically connected to the electrical system 241.

[0152] In this embodiment, by setting up a high-voltage box 213 and a busbar, an orderly connection and efficient power transmission between multiple battery packs 214 are achieved, thereby improving the stability of the entire battery system 210 operation.

[0153] In some embodiments, such as Figure 3 and Figure 10 As shown, the battery rack 211 includes a column 2111, which serves to support and fix the battery rack 211, and can also be used to guide or carry other components and cables.

[0154] In some embodiments, the column 2111 extends along the height direction of the box 2, and some of the multiple storage compartments 212 are arranged along the extension direction of the column 2111.

[0155] The external port on the high-voltage box 213 is electrically connected to the busbar 215 located at the bottom of the battery compartment 21 via a connecting cable to transmit power or signals so that the battery pack 214 inside the battery compartment 21 can work normally or be charged.

[0156] The connecting cable extends along the column 2111, which provides a fixed path for the connecting cable, allowing the connecting cable to be neatly and orderly connected to the high-voltage box 213 and the battery compartment 21, facilitating later maintenance and repair.

[0157] The connection cable is fixed to the column 2111, which can reduce the loosening or damage of the connection cable when it is moved or vibrated, and also improve the stability and safety of the system.

[0158] In some embodiments, a plurality of columns 2111 are spaced apart along the length of the housing 2.

[0159] In this embodiment, a battery rack 211 may include at least one column 2111, and multiple battery racks 211 may include multiple columns 2111. The multiple battery racks 211 are arranged along the length direction of the housing 2, and the multiple columns 2111 are arranged along the length direction of the housing 2.

[0160] like Figure 3 and Figure 10 As shown, the battery rack 211 also includes multiple mounting parts 2112, which are spaced apart along the height of the column 2111. The mounting parts 2112 can be threaded, snapped, or welded to the column 2111.

[0161] Each column 2111 may include at least one mounting component 2112. The mounting components 2112 on the same layer of two adjacent columns 2111 are set at the same height. The mounting components 2112 on the same layer of two adjacent columns 2111 form a storage compartment 212. The mounting component 2112 serves to fix the high voltage box 213 or battery pack 214.

[0162] Mounting component 2112 can be an L-shaped connector or a guide rail. Mounting component 2112 is located at the bottom of high voltage box 213 or battery pack 214. Mounting component 2112 can play a supporting and fixing role.

[0163] The mounting components 2112 on two adjacent columns 2111 located on different layers can be set at the same height as the high voltage box 213 or battery pack 214 to be fixed, so as to fix high voltage boxes 213 or battery packs 214 of different heights at different heights.

[0164] The mounting components 2112 on the same layer of multiple columns 2111 are set at the same height. In other words, on the same horizontal plane of the battery rack 211, the mounting components 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.

[0165] Two mounting pieces 2112 on the same floor of adjacent columns 2111 form a storage compartment 212. The storage compartment 212 on the same floor can hold the same type of high voltage box 213 or battery pack 214, so as to facilitate classification and placement, reduce the difficulty of inspection and maintenance, and facilitate maintenance.

[0166] Two mounting brackets 2112 on the same level on adjacent columns 2111 together form a storage compartment 212. This design allows the battery rack 211 not only to hold batteries or equipment, but also to provide additional storage space for tools, spare parts, or other necessities. The storage compartment 212 increases the practicality and functionality of the battery rack 211.

[0167] In some embodiments, a shim is provided at the bottom of the battery rack 211 to raise the height of the battery rack 211, thereby reducing the interference of the raised side beam 26 on the battery rack 211.

[0168] The shim can be a square tube.

[0169] In some embodiments, the bottom of the shim and the battery rack 211 is provided with a shock absorber, which is used to reduce the vibration of the battery rack 211 during the movement and hoisting of the energy storage device and improve the reliability of various electrical connections on the battery rack 211.

[0170] In some embodiments, such as Figure 8 As shown, the battery compartment 21 also includes a dehumidifier 30, which is installed on the top of the battery rack 211 to dehumidify the air inside the battery compartment 21, thereby improving the dryness inside the battery compartment 21 and enhancing the reliability and safety of the electrical connections inside the battery compartment 21.

[0171] In some embodiments, such as Figure 8As shown, the box body 2 includes connected side beams 26 and bottom plate 271. The bottom plate 271 is installed on the side beams 26. The side beams 26 and bottom plate 271 can be tightly connected by welding and bolts to form a stable overall structure.

[0172] 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.

[0173] The upper surface of the base plate 271 is recessed downward relative to the upper surface of the side beam 26. In other words, the side beam 26 is designed to be raised to increase the structural strength of the side beam 26, improve the rigidity and fatigue resistance of the box 2, and thus extend the service life of the box 2 in application scenarios where the energy storage device 200 is frequently hoisted.

[0174] In this embodiment, the heightening design of the longitudinal beams on both sides of the base plate 271 along the width direction will cause the upper surface of the base plate 271 to be recessed downward relative to the upper surface of the side beam 26, thereby making the internal mounting plane of the box 2 lower than the external plane.

[0175] In some embodiments, the longitudinal bottom beam 261 extends along the length direction of the box body 2 and is spaced apart at the ends of the bottom plate 271 along the width direction. Since the longitudinal bottom beam 261 is heightened 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. The bottom plate 271 is disposed above the transverse bottom beam 262. The transverse bottom beam is used to define the positions of the longitudinal bottom beams 261 at both ends and improve the structural stability of the box body 2.

[0176] In some embodiments, such as Figure 8 As shown, the enclosure 2 also includes a fireproof partition layer 272.

[0177] Among them, the fireproof partition layer 272 can be made of fireproof materials. The fireproof materials can be inorganic fiber materials such as rock wool, glass wool, and aluminum silicate fiber, or composite materials such as intumescent fireproof coatings and fireproof boards.

[0178] For example, fire-resistant partition 272 may be made of A60 fire-resistant material.

[0179] The base plate 271 is disposed between the fire-resistant partition layer 272 and the transverse bottom beam 262, and the upper surface of the fire-resistant partition layer 272 is recessed downward relative to the upper surface of the longitudinal bottom beam 261.

[0180] 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 fireproof partition layer 272. The increased height 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 2, thereby extending the service life of the box 2 in application scenarios where the energy storage device 200 is frequently hoisted.

[0181] In this configuration, multiple battery packs 214 arranged in the same battery rack 211 are connected in series sequentially, and the high-voltage box 213 is electrically connected to two adjacent battery packs 214 in the series direction.

[0182] Within the same battery rack 211, the high-voltage box 213 and 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.

[0183] The high-voltage box 213 is located in the storage compartment 212 on the second layer from the bottom. 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.

[0184] In this embodiment, when arranging the battery clusters inside the housing 2, the high-voltage box 213 is raised, that is, the high-voltage box 213 is not placed in the storage compartment 212 closest to the bottom plate 271. Compared with placing the high-voltage box 213 in the bottom storage compartment 212, it is more convenient for the maintenance and repair of the high-voltage box 213.

[0185] Understandably, since the upper surface of the base plate 271 is recessed downwards relative to the upper surface of the side beam 26, at least a portion of the bottom storage compartment 212 is located in the recessed area of ​​the base plate 271 relative to the side beam 26, and the opening of the bottom storage compartment 212 may be obstructed by the upper surface of the side beam 26. Considering that the high-voltage box 213 is maintained more frequently than the battery pack 214, if the high-voltage box 213 is placed in the bottom storage compartment 212, the upper surface of the side beam 26 will interfere with the action of taking out the high-voltage box 213 or opening the door of the high-voltage box 213 during maintenance, increasing the difficulty of maintenance.

[0186] In some embodiments, such as Figure 8 As shown, the height of the side beam 26 is H, which satisfies the condition: 150mm≤H≤400mm. For example, the height H of the side beam 26 can be 150mm, 200mm, 350mm or 400mm.

[0187] In this embodiment, by increasing the height of the side beam 26, the structural strength of the side beam 26 can be increased, and the rigidity and fatigue resistance of the box 2 can be improved. This extends the service life of the box 2 in application scenarios where the energy storage device 200 is frequently hoisted, so as to meet the usage requirements of the battery swapping energy storage device.

[0188] In typical energy storage devices, there are usually battery packs and high-voltage boxes. The battery packs and high-voltage boxes are stacked together, with the high-voltage box located at the bottom, which presents a problem of inconvenient maintenance.

[0189] The energy storage device 200 provided in this application embodiment can be a rechargeable energy storage device or a battery swapping energy storage device. This application embodiment also provides a battery swapping energy storage device, which includes: a housing 2 and a battery pack.

[0190] The housing 2 forms the battery compartment 21.

[0191] The battery pack is installed in the battery compartment 21 and supported on the base plate 271. The battery pack includes a high voltage box 213 and multiple battery packs 214. The high voltage box 213 and multiple battery packs 214 are stacked in multiple layers. The external port of the battery pack is located in the high voltage box 213, and at least one battery pack 214 is located below the high voltage box 213.

[0192] like Figure 3 and Figure 10 As shown, the battery pack also includes one or more battery racks 211, each of which has multiple storage compartments 212, each of which is used to house a high-voltage box 213 or a battery pack 214.

[0193] The number of battery racks 211 can be flexibly expanded as needed, and multiple battery racks 211 can be arranged along the length and / or width of the housing 2.

[0194] For example, the battery rack 211 can be arranged in two columns along the width direction of the housing 2, each column including multiple battery racks 211, and the multiple battery racks 211 extend along the length direction of the housing 2.

[0195] For example, each battery rack 211 includes two rows of multi-layer storage compartments 212. One of the multiple storage compartments 212 in 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.

[0196] The battery rack 211 can extend along the height direction of the housing 2, and multiple storage compartments 212 can be arranged along the height direction of the battery rack 211 to make full use of the height space of the housing 2, improve the space utilization rate of the housing 2, and increase the energy density of the energy storage device 200.

[0197] Storage compartment 212 is used to install and secure high-voltage box 213 or battery pack 214 to improve the stability and reliability of battery system 210 operation.

[0198] Among them, such as Figure 3As shown, the high-voltage box 213 is located in the storage compartment 212 on the second or higher layer from the bottom. In other words, one or more battery packs 214 may be provided below the high-voltage box 213 to move the installation position of the high-voltage box 213 away from the base plate 271.

[0199] According to the battery swapping energy storage device provided in the embodiments of this application, by raising the high-voltage box 213, it is easier to maintain and repair the high-voltage box 213 compared to setting the high-voltage box 213 in the bottom storage compartment 212.

[0200] In typical battery-swapping energy storage devices, the energy storage device usually needs to be frequently hoisted and moved. During the hoisting process, the container is prone to collision damage. The rigidity and fatigue resistance of the container are crucial to its service life.

[0201] In some embodiments, the housing 2 includes a connected side beam 26 and a bottom plate 271. The bottom plate 271 is mounted on the side beam 26. The height of the side beam 26 is H, which satisfies: 150mm≤H≤400mm, and the upper surface of the bottom plate 271 is recessed downward relative to the upper surface of the side beam 26.

[0202] In this embodiment, by increasing the height of the side beam 26, the structural strength of the side beam 26 can be increased, and the rigidity and fatigue resistance of the box 2 can be improved. This extends the service life of the box 2 in application scenarios where the energy storage device 200 is frequently hoisted, so as to meet the usage requirements of the battery swapping energy storage device.

[0203] 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.

[0204] With the high-voltage box 213 and multiple battery packs 214 installed in the storage compartment 212 of the battery rack 211, the high-voltage box 213 is located in the second-to-last storage compartment 212 from the bottom.

[0205] Since multiple battery packs 214 within the same battery group are connected to the busbar 215 via the high-voltage box 213, and the busbar 215 of the multiple battery packs are electrically connected to the electrical system 241 after being arranged in parallel at the bottom of the enclosure 2, by placing only one battery pack 214 below the high-voltage box 213, the high-voltage box 213 can be separated from the base plate 271, so that the high-voltage box 213 controlling this cluster can be maintained and repaired when the side beam 26 is raised. It can also shorten the distance of the busbar 215 of the high-voltage box 213 to the bottom of the enclosure 2, reduce the wiring length, reduce the difficulty of wiring, and facilitate inspection and maintenance.

[0206] In some embodiments, the two ends of the battery pack 214 are arranged along the width direction of the housing 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.

[0207] In some embodiments, multiple battery packs 214 within the same battery pack are connected in series sequentially, and a 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 sequentially, which simplifies the circuit connection of the battery system 210 and improves the overall efficiency of the battery system 210.

[0208] The same battery pack can be located in a battery rack 211 or stacked in the housing 2.

[0209] 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 in multiple layers to make full use of the height space of the box 2 to improve the energy density of the energy storage device. At the same time, the two rows can form an air circulation channel between adjacent rows to improve the heat dissipation effect of the high-voltage box 213 and multiple battery packs 214.

[0210] In some embodiments, such as Figure 8 As shown, the lower surface of the side beam 26 is provided with protrusions. The protrusions extend along the length direction of the box body 2. The protrusions can be strip structures 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 they can be protrusions that are spaced apart and arranged along the length direction of the box body 2.

[0211] In this embodiment, the protrusion is used to separate the box 2 from the ground so as to facilitate the hoisting of the box 2.

[0212] In some embodiments, such as Figure 8 As shown, the housing 2 also includes a side plate 273 and a water-blocking baffle 274. The side plate 273 and the bottom plate 271 form a battery compartment 21 for accommodating the battery pack. The bottom end of the side plate 273 is connected to the upper surface of the side beam 26. The water-blocking baffle 274 is disposed on the upper surface of the side beam 26 and located on the outer surface of the side plate 273.

[0213] The water-blocking edge 274 is used to increase the sealing of the connection between the side beam 26 and the side plate 273, reduce the risk of water or other debris leaking into the box 2 from the connection between the side beam 26 and the side plate 273, and improve the sealing and structural stability of the box 2.

[0214] The water-blocking edge 274 is connected to the upper surface of the side beam 26 and the outer surface of the side plate 273 respectively. The water-blocking edge 274 can be connected to the upper surface of the side beam 26 and the outer surface of the side plate 273 by welding, threaded connection or adhesive.

[0215] In some embodiments, the water-blocking baffle 274 includes a first baffle and a second baffle connected together. 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 side beam 26, and the inner surface of the second baffle is connected to the outer surface of the side plate 273.

[0216] The first baffle and the second baffle can be bent at a relative angle of 90°, and the first baffle and the second baffle can be integrated into a single structure.

[0217] In this embodiment, by setting a water-blocking edge 274 structure in which the first baffle is bent relative to the second baffle, the waterproof performance and structural stability of the housing 2 can be improved, thereby enhancing the safety of the battery system 210 and reducing the difficulty and cost of installation and maintenance.

[0218] In some embodiments, such as Figure 10 As shown, multiple storage compartments 212 within the same battery rack 211 are arranged in layers. The 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 rows of storage compartments 212. The multiple storage compartments 212 are distributed along the layer array. The limited volume of the battery rack 211 can be fully utilized through a regular arrangement, thereby increasing the energy density of the energy storage device 200.

[0219] Multiple battery packs 214 arranged in the same layer within the same battery rack 211 are arranged along the arrangement direction of the multiple battery racks 211. By neatly placing the battery packs 214 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.

[0220] 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 primary water supply pipe 2171, a primary water return pipe 2172, a secondary water supply pipe 2173, a secondary water return pipe 2174, a tertiary water supply pipe 2175, a tertiary water return pipe 2177, and a room connection pipe 2176.

[0221] 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.

[0222] The primary 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 (e.g., from the front end to the rear end of the housing 2, from the left end to the right end of the housing 2). The primary water supply pipe 2171 is responsible for providing cooling circulating water to each battery rack 211.

[0223] The primary return water pipe 2172 corresponds to the primary water supply pipe 2171, and the primary return water pipe 2172 also extends along the arrangement direction of the multiple battery racks 211. The primary return water pipe 2172 is responsible for collecting the circulating water flowing out from each battery pack 214 and sending it back to the main unit 2211 of the temperature control system 221 for further cooling.

[0224] The primary water supply pipe 2171 and the primary water return pipe 2172 are arranged opposite each other on the upper and lower sides of the battery rack 211 along the height direction. For example, the primary water supply pipe 2171 can be arranged above the battery rack 211 and the primary water return pipe 2172 can be arranged below the battery rack 211; or, the primary water supply pipe 2171 can be arranged below the battery rack 211 and the primary water return pipe 2172 can be arranged above the battery rack 211.

[0225] The secondary water supply pipe 2173 and the secondary water return pipe 2174 both extend vertically and are respectively arranged on both sides of the battery rack 211.

[0226] A secondary water supply pipe 2173 branches off from the primary water supply pipe 2171, extends vertically (i.e., along the height of the battery rack 211), and is located on one side of the battery rack 211 (e.g., the left side). The secondary water supply pipe 2173 is responsible for distributing the circulating water in the primary water supply pipe 2171 to the battery packs 214 in different layers within the same battery rack 211.

[0227] The secondary return water pipe 2174 corresponds to the secondary supply water pipe 2173. The secondary return water pipe 2174 also extends vertically (i.e., along the height of the battery rack 211) and is located on the other side of the battery rack 211 (e.g., the right side). The secondary return water pipe 2174 is responsible for collecting the circulating water flowing out from different layers of battery packs 214 within the corresponding battery rack 211 and returning it to the primary return water pipe 2172.

[0228] 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 the adjacent battery pack 214.

[0229] The tertiary water supply pipe 2175 branches off from the secondary water supply pipe 2173 and connects to the inlet of the heat exchanger 216 corresponding to the adjacent battery pack 214. The tertiary water supply pipe 2175 ensures that each battery pack 214 receives circulating cooling water.

[0230] The heat exchange devices 216 corresponding to multiple battery packs 214 on the same layer within the same battery rack 211 are connected by the compartment connecting pipe 2176.

[0231] The compartment connecting pipe 2176 is installed between multiple battery packs 214 on the same layer within the same battery rack 211, and the multiple battery packs 214 on the same layer are connected by the compartment 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.

[0232] The tertiary return water pipe 2177 is connected between the secondary return water pipe 2174 and the outlet of the heat exchange device 216 corresponding to the adjacent battery pack 214.

[0233] The tertiary return water pipe 2177 corresponds to the tertiary supply water pipe 2175. The tertiary return water pipe 2177 is connected between the secondary return water pipe 2174 and the outlet of the heat exchange device 216 corresponding to the adjacent battery pack 214. The tertiary return water pipe 2177 is responsible for sending the circulating water after passing through the heat exchange device 216 back to the secondary return water pipe 2174.

[0234] In this embodiment, the design of connecting the main unit 2211 of the temperature control system 221 and the heat exchange device 216 through the temperature control circulation pipeline 217 can improve the precise control of the temperature of each battery pack 214 by the temperature control system 221, so that the battery pack 214 always works within a suitable temperature range, thereby improving the overall performance and safety of the energy storage device 200.

[0235] The main unit 2211 of the temperature control system 221 can be placed inside the temperature control chamber 22. It exchanges heat with the outside through the heat exchange louvers on the walls of the temperature control chamber 22. The temperature control circulation pipeline 217 is connected to the battery pack 214 in the battery compartment 21 to regulate the temperature of the battery pack 214, thereby keeping the battery system 210 in a suitable temperature and humidity environment.

[0236] In conventional energy storage devices, users cannot intuitively and effectively control the various modules within the device, nor can they easily understand the device's operational status, necessitating improvements.

[0237] In some embodiments, such as Figure 9 and Figure 10 As shown, the first end face 28 along the length direction of the enclosure 2 is provided with an interaction area 281. The first end face 28 can be the front or rear end of the enclosure 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 enclosure 2.

[0238] The interactive area 281 includes at least a portion of an interactive panel 28111, a prompting device 28112, an operating device, and a plug-in interface 28122.

[0239] The interactive panel 28111 can be a display screen or a touch screen, such as a 10-inch display screen. The interactive panel 28111 is used to display system status information, alarm information, operation instructions, etc., and allows users to input operations via touch or buttons. The interactive panel 28111 may include a graphical user interface (GUI), enabling users to intuitively understand the system status and perform control.

[0240] The alerting device 28112 may be an LED indicator, a buzzer, or other type of alarm. These are used to provide visual or auditory alerts to the user when the system status changes or a malfunction occurs. For example, when the temperature inside the battery compartment 21 is too high, a red LED indicator may light up, and a buzzer may sound an alarm.

[0241] The operating devices include physical controls such as buttons, knobs, and switches, allowing users to directly operate the system. These operating devices may be used to start or stop the fan 233, open or close the dampers, or reset the alarm system, etc.

[0242] The connector 28122 is used to connect external devices, such as laptops, data loggers, or repair tools. These may include USB interfaces, Ethernet interfaces, serial communication interfaces, etc. These connectors 28122 enable users to easily access system data, perform system upgrades, or perform repairs.

[0243] Interactive area 281 may have the following functions:

[0244] Information display: Real-time status information of the energy storage device 200, such as battery compartment temperature 21, air intake duct speed 231, and exhaust duct pressure 234, is displayed through the interactive panel 28111.

[0245] Alarm notification: When the energy storage device 200 detects an abnormal situation, it sends an alarm signal to the user through the notification device 28112 and displays detailed alarm information on the interactive panel 28111.

[0246] Operation and control: Allows users 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 fire from spreading, etc.

[0247] Data interaction: Exchange data with external devices through interface 28122, such as exporting energy storage device 200 logs and uploading configuration files.

[0248] In this embodiment, by setting up the interactive area 281, an intuitive and convenient operating interface is provided for users, enabling them to easily understand the status of the energy storage device 200 and perform necessary operations and handle abnormal situations. Meanwhile, the presence of the plug-in interface 28122 also enhances the system's scalability and maintainability.

[0249] This application embodiment also provides an energy storage device 200, including:

[0250] The housing 2 forms a battery compartment 21 and an electrical compartment 24. The battery compartment 21 is equipped with a battery system 210, and the electrical compartment 24 is equipped with an electrical system 241 that is electrically connected to the battery system 210. The first end face 28 of the housing 2 along the length direction is provided with an interaction area 281. The interaction area 281 is provided with at least a portion of an interaction panel 28111, a prompting device 28112, an operating device, and a plug-in interface 28122.

[0251] The battery system 210 may include a high-voltage box 213 and multiple battery packs 214, and the battery system 210 is used to store electrical energy.

[0252] 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 monitors and manages the status of the battery system 210, including parameters such as voltage, current, and temperature of the battery pack 214. The DC / AC converter converts the DC power supplied by the battery system 210 into AC power for use by external devices. Electrical protection components such as circuit breakers and relays protect the safe operation of electrical system 241 and prevent faults such as short circuits and overloads.

[0253] The electrical system 241 is electrically connected to the battery system 210. The electrical system 241 and the battery system 210 can be electrically connected through cables and connectors to realize the transmission and control of electrical energy.

[0254] According to the energy storage device 200 provided in this embodiment, by setting the housing 2 of the energy storage device 200 as a separate battery compartment 21 and electrical compartment 24, the battery system 210 inside the housing 2 of the energy storage device 200 can be electrically controlled; and by setting the interactive area 281, an intuitive and convenient operating interface is provided for users, enabling them to easily understand the status of the energy storage device 200 and perform necessary operations and handle abnormal situations; at the same time, the existence of the plug interface 28122 also enhances the scalability and maintainability of the system.

[0255] 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, and the two are separated by a partition or other structure inside the housing 2. This layout helps to 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.

[0256] like Figure 9 and Figure 10 As shown, the first end face 28 is the end face closest to the electrical compartment 24, and the interaction area 281 faces the electrical compartment 24, allowing users to perform interactive operations from a position close to the electrical system 241. This helps users to more conveniently access the status information of the electrical system 241, perform necessary operations, and handle abnormal situations. At the same time, it also facilitates the maintenance and repair of the electrical system 241.

[0257] In some embodiments, the interaction area 281 is located on the front side of the first end face 28. The front side of the first end face 28 is located in a position that the user can directly see and touch when facing the housing 2, so that the user can access and operate the interaction area 281 at different heights, thereby improving the comfort and flexibility of use.

[0258] The interactive area 281 extends upwards from the bottom, covering part or all of the front area of ​​the first end face 28. This design allows users to access the interactive panel 28111, prompting device 28112, operating device, and interface 28122 from different heights, thereby improving the flexibility and convenience of interaction.

[0259] like Figure 9 and Figure 10 As shown, in some embodiments, the interactive panel 28111, the prompting device 28112, the operating device, and the plug interface 28122 do not protrude from the first end face 28.

[0260] In this embodiment, all or part of the interactive panel 28111, prompting device 28112, operating device and interface 28122 can be flush with the first end face 28, or all or part of the interactive panel 28111, prompting device 28112, operating device and interface 28122 can be recessed inward relative to the first end face 28. This not only makes the overall appearance of the energy storage device 200 simpler and more beautiful, but also reduces the risk of accidental collision or damage to the energy storage device 200 due to component protrusion during placement or hoisting, and improves the safety of the hoisting process.

[0261] In some embodiments, such as Figure 9 and Figure 10As shown, the interactive area 281 includes a first area 2811 and a second area 2812 arranged from top to bottom.

[0262] The first area 2811 is equipped with an interactive panel 28111, a prompting device 28112, and a portion of the operating devices. The first area 2811 is positioned at the top or above the interactive area 281, which makes it easier for users to find the required operating interface and information display area more quickly, thereby improving user efficiency and satisfaction.

[0263] The second area 2812 is located at the bottom or below the interactive area 281. The second area 2812 is equipped with some operating devices and interfaces 28122, which are in line with the operating habits of the crew and improve operability.

[0264] In this embodiment, this partitioning design makes the functional layout of the interaction area 281 clearer and more reasonable, helping users to find the required operation interface and information display area more quickly.

[0265] In some embodiments, such 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 the operating device and the plug interface 28122, which conforms to the operating habits of the crew and improves operability.

[0266] In some embodiments, such 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 prompting device 28112 and a portion of the operating devices. Setting the first area 2811 at the top or above the interactive area 281 makes it easier for users to quickly find the required operating interface and information display area, improving user efficiency and satisfaction.

[0267] In some embodiments, such as Figure 9 and Figure 10 As shown, the first area 2811 is provided with a maintenance window 282 that can be opened and closed and connected to the housing 2. The maintenance window 282 can be pivotally connected to the housing 2.

[0268] In this embodiment, the first area 2811 is designed as an openable and closable maintenance window 282. The maintenance window 282 can be opened or closed relative to the housing 2 to allow the user to maintain, repair, or replace components on the interaction area 281. The maintenance window 282 and the housing 2 can be sealed together to improve the sealing and security of the housing 2 when the maintenance window 282 is closed.

[0269] The interactive panel 28111, prompting device 28112, and 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 to perform necessary maintenance or repair work. When the maintenance window 282 is closed, the interactive panel 28111 can still be displayed and operated normally.

[0270] In some embodiments, such as Figure 9 and Figure 10 As shown, the 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 to easily perform connection operations.

[0271] The communication output interface 281222 is a heavy-duty connector socket for the energy storage device 200 to transmit communication signals at the ship's end or shore end.

[0272] The AC input interface 281221 is an input connector socket used to start and stop the energy storage device 200 by introducing AC voltage from the outside in emergency situations.

[0273] The DC input / output interface 281223 is a connector socket for charging and discharging energy storage device 200 with the ship's end or with the shore end.

[0274] The operating device located in the first area 2811 includes an interface communication switch 28113.

[0275] Above the interactive panel 28111 is a prompting device 28112 for indicating the working status of each compartment.

[0276] Below the interactive panel 28111 is an interface communication switch 28113 for controlling the communication connection status of the AC input interface 281221 and the DC input / output interface 281223.

[0277] The operating device located in the second area 2812 includes a control box 281211 and an emergency fire extinguishing device 281212. The control box 281211 and the emergency fire extinguishing device 281212 are located above the plug-in interface 28122 in the second area 2812, which facilitates quick and accurate operation by the user.

[0278] The control box 281211 has built-in start / stop buttons, local / remote switching knobs and system emergency stop buttons for the energy storage device 200, in order to reduce the risk of accidental collisions or damage to the energy storage device 200 during placement or hoisting, and to improve the protection of the control buttons inside the control box 281211.

[0279] The emergency fire extinguishing control unit 281212 can be a manual button, which can be used to manually start / stop the fire protection system 230 in an emergency.

[0280] In this embodiment, a more intuitive, user-friendly, 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.

[0281] In some embodiments, such as Figure 9 and Figure 10 As shown, the interface 28122 includes an AC input interface 281221 and a DC input / output interface 281223.

[0282] For example, the box-type power supply has six external DC input / output interfaces 281223, which use standard DC charge / discharge connectors.

[0283] The DC input / output interface 281223 can use a standard DC charging / discharging connector, which is beneficial to promoting standardization in the marine electrification industry.

[0284] In some embodiments, the DC input / output interface 281223 can be placed in an area 0.3m to 1m from the bottom of the enclosure 2, for example, the DC input / output interface 281223 can be placed at a position about 0.6m from the bottom of the enclosure 2.

[0285] In this embodiment, considering that when the crew connects the DC connector, they need to drag the plug of the DC connector and the rear connection cable, in order to improve the efficiency of power swapping and the operability of installing the connector, the DC input / output interface 281223 is placed at a position about 0.6m 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 ship's power supply when the ship is rocking.

[0286] In some embodiments, such as Figure 9 and Figure 10 As shown, there are multiple interface communication switches 28113, which are arranged in different positions in the interaction area 281 to meet different connection requirements.

[0287] A portion of the interface communication switches 28113 correspond one-to-one with the plug interfaces 28122. The communication switches can individually control the communication connection status of each plug interface 28122. Users can enable or disable the communication function of a specific plug interface 28122 as needed to meet the requirements of different application scenarios.

[0288] A portion of the interface communication switches 28113 are used to control the communication connection status of multiple plug interfaces 28122, so as to simplify the user's operation process and improve the operation efficiency.

[0289] 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 combiner cabinet in the electrical compartment 24, thereby reducing the length of communication cables and DC cables used and lowering production costs.

[0290] 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 arranged in a certain order in the storage compartments 212 of the battery rack 211. The high-voltage box 213 combines the capacity of the 15 battery packs 214 and is placed on the second layer at the bottom of the battery rack 211 for easy maintenance and repair. At the same time, the high-voltage boxes 213 of each cluster output to the combiner cabinet in parallel. The combiner cabinet uniformly outputs to the output / input interface of the box power supply.

[0291] Secondly, embodiments of this application also provide an electric vessel, including: an energy storage device as described in any of the above embodiments, the energy storage device being used to provide electrical energy to the electric vessel.

[0292] The energy storage device can be either a battery swapping energy storage device or a rechargeable energy storage device. Electric ships can replenish their energy through battery swapping or recharging.

[0293] In some embodiments, the electric vessel is provided with a battery mounting location, and an energy storage device is detachably mounted at the battery mounting location.

[0294] The battery can be installed on the deck of the electric vessel, such as at the stern, which helps improve battery swapping efficiency and reduces interference with other operations of the electric vessel.

[0295] In this embodiment, the electric vessel is a battery-swapping vessel. Compared with charging vessels, the electric vessel of this application adopts battery-swapping for energy replenishment, which can greatly improve the energy replenishment efficiency of the electric vessel, reduce costs, solve range anxiety, increase the working time of the electric vessel, and thus increase revenue.

[0296] In some embodiments, the battery mounting location may be provided with a fixing device, such as a quick-locking structure, for selectively locking the energy storage device. The locking structure may be electrically driven, such as including a driver and an electric latch driven by the driver; or the locking structure may be mechanical, such as including a plug-in device that is elastically mounted on the battery mounting location. The battery mounting location may also be provided with a floating plug-in connector for electrical connection with the energy storage device.

[0297] The battery mounting location is equipped with a fixing device, which enables quick and safe connection and disconnection between the battery mounting location and the energy storage device, facilitating battery swapping operations.

[0298] In some embodiments, the battery mounting location is further provided with a fastener mounting position. The fastener can be a binding rod or a fastening strap. The battery mounting location and the energy storage device can be connected and fixed using the fastener.

[0299] For example, in severe weather or sea conditions, the battery installation location and the energy storage device can be connected simultaneously using fixing devices and fasteners to increase the stability of the connection between the battery installation location and the energy storage device and reduce the movement of the energy storage device in severe weather or sea conditions.
