Description

Technical Field

[0001] This utility model relates to the field of energy storage system technology, and in particular to a three-compartment sodium salt solid energy storage compartment. Background Technology

[0002] With the acceleration of the global energy transition, the demand for large-scale grid connection of renewable energy sources such as wind and solar power is becoming increasingly urgent. As a core component for mitigating the volatility of new energy sources and ensuring the stable operation of the power grid, energy storage systems have attracted much attention for their technical performance and economic efficiency. Currently, lithium-ion battery energy storage systems dominate the energy storage market due to their high technological maturity and high energy density, but they have gradually revealed many inherent defects during long-term operation.

[0003] In current mainstream energy storage system integration solutions, whether centralized, distributed, or modular, batteries, electrical equipment, and control equipment are generally mixed and arranged in the same space or lack systematic integration, leading to the following prominent problems:

[0004] First, functional modules interfere with each other. The heat generated during battery compartment operation affects the operational stability of precision control equipment; strong electromagnetic interference generated by electrical equipment affects the reliability of control signals; and different functional modules interfere with each other during maintenance, resulting in low maintenance efficiency.

[0005] Secondly, there are high safety risks during operation and maintenance. The energy storage cabinet contains a high-voltage DC circuit. If maintenance personnel do not strictly adhere to power-off procedures when opening the hatch for inspection, electric shock accidents are highly likely. Although some systems are equipped with emergency stop buttons or software-level power-off controls, the lack of a hardware disconnect mechanism linked to the hatch door poses a safety hazard.

[0006] Third, the system control reliability is insufficient. In abnormal situations such as power grid interruption, if the core control equipment (such as the energy management system) loses power, the energy storage system will become uncontrollable, and real-time monitoring of battery status and fault response will be impossible.

[0007] Therefore, how to develop a compact, safe, reliable, and intelligent energy storage system structure integration scheme based on the inherent advantages of sodium-ion solid-state batteries has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of existing lithium battery energy storage systems, such as strong resource dependence, poor safety, and weak low-temperature adaptability. In addition, it addresses the problems of mutual interference between functional modules, high operation and maintenance safety risks, and insufficient system control reliability in existing energy storage system integration schemes, and provides a compact, stable, and cost-controllable sodium salt solid-state energy storage system structure integration technology.

[0009] To achieve the above objectives, this utility model provides a three-compartment sodium salt solid-state energy storage compartment, comprising an integrated compartment body, the interior of which is physically divided into three independent compartments: a battery compartment, an electrical compartment, and a control compartment. The battery compartment houses multiple sodium salt solid-state battery packs, each connected to a corresponding battery management system for one-to-one battery status monitoring. The battery compartment has an independent battery compartment door. A cut-off mechanism linked to the battery compartment door is also provided within the battery compartment to cut off the output power of the sodium salt solid-state battery packs when the battery compartment door is opened. The electrical compartment houses an energy storage converter and a main power circuit breaker. The system includes a busbar; multiple sodium-ion solid-state battery packs are connected to the DC side of the energy storage converter via the busbar, and the AC side of the energy storage converter is used to connect to the power grid or load; the main power circuit breaker is connected in series between the busbar and the DC side of the energy storage converter as a primary protection for the DC side; the control compartment is equipped with an energy management system and an uninterruptible power supply (UPS); the energy management system is communicatively connected to the battery management system and the energy storage converter, respectively, for receiving battery status data and issuing charging and discharging strategies; the UPS is electrically connected to the energy management system and the core control equipment in the control compartment, respectively, for maintaining power supply when the main power is interrupted.

[0010] The battery compartment is also equipped with at least one low-power LED light.

[0011] The electrical compartment is also equipped with a PCS power circuit breaker, which is connected in series between the busbar and the DC side of the energy storage converter to form a secondary protection circuit.

[0012] The busbar includes a positive busbar and a negative busbar, which are connected to the positive and negative terminals of the sodium-ion solid-state battery pack, respectively; the conductive cross-section of the positive busbar and the negative busbar is ≥120mm². 2 The electrical compartment is also equipped with a grounding copper busbar for grounding the entire machine.

[0013] The electrical compartment is also equipped with a surge protector. One end of the surge protector is connected to the AC bus between the AC side of the energy storage converter and the power grid, and the other end is connected to the grounding copper busbar. The maximum discharge current Imax of the surge protector is ≥20kA, which is used to suppress overvoltage on the power grid side.

[0014] The core control equipment in the control cabin includes a touch control screen, which is connected to the energy management system and the uninterruptible power supply to provide a local human-machine interface.

[0015] The core control equipment inside the control cabin also includes an industrial and commercial energy storage terminal, which is communicatively connected to the energy management system and used for data interaction with the external power distribution system.

[0016] The control cabin is also equipped with a low-voltage circuit breaker for overload and short-circuit protection of the control and communication circuits.

[0017] The output power of the uninterruptible power supply is ≥1kVA.

[0018] The battery compartment, electrical compartment, and control compartment are arranged in a triangular or linear pattern within the integrated compartment.

[0019] As can be seen from the above technical solutions, the advantages of this utility model are:

[0020] This utility model, through an integrated design of "three-compartment physical isolation + safety interlock + intelligent control," fully leverages the inherent safety advantages of sodium-ion solid-state batteries and systematically solves core problems of traditional energy storage systems, such as mutual interference between functional modules, high operational and maintenance safety risks, and insufficient control reliability. Specifically: the physical isolation design of the battery compartment, electrical compartment, and control compartment fundamentally avoids interference from battery heat to control equipment, electromagnetic interference from strong electrical magnetic fields to signals, and mutual interference during maintenance; the battery compartment door linkage cut-off mechanism achieves hardware-level safety interlocking of "instant power cut-off upon door opening," completely eliminating the risk of high-voltage electric shock; the battery management system (BMS) and sodium-ion solid-state battery pack provide a precise data foundation for energy dispatch through "one-to-one" monitoring; the energy storage converter, main power circuit breaker, and busbar construct a complete power transmission channel; the energy management system (EMS) and uninterruptible power supply (UPS) work together to form an intelligent closed-loop control of "monitoring-decision-execution," with the UPS maintaining power supply to core equipment when the main power is interrupted, ensuring that the system does not lose control or crash. This invention achieves synergistic improvements in space utilization, electromagnetic compatibility, operation and maintenance safety, and control reliability, demonstrating significant technological advancements.

[0021] Further technical solutions of this utility model have been comprehensively optimized in terms of safety protection and system efficiency. By installing PCS power circuit breakers and surge protectors (Imax≥20kA) in the electrical compartment, a two-level protection architecture of "main circuit-branch circuit" is constructed, effectively suppressing overvoltage impacts on the power grid side; grounding copper busbars are installed to achieve equipotential bonding of the entire unit, and the busbar adopts a large cross-section design of ≥120mm², significantly reducing line losses, thereby improving the system's fault isolation capability, equipment lifespan, and energy conversion efficiency from multiple dimensions.

[0022] In terms of intelligent operation and maintenance and system reliability, an intuitive human-machine interface is provided by setting up a touch control screen, an industrial and commercial energy storage terminal (EMU), and a low-voltage circuit breaker. This enables data interaction with the external power distribution system and advanced scenario linkage such as demand response and peak-valley arbitrage, while also providing overload protection for the control circuit. Low-power LED lighting (e.g., ≤10W) provides illumination for maintenance inside the cabin and avoids additional heat sources. UPS power ≥1kVA ensures the complete operation of core equipment when the main power is interrupted. The triangular or linear arrangement provides a flexible integration method, making this utility model a complete technical system in terms of safety redundancy, intelligent control, and ease of operation and maintenance.

[0051] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0052] This utility model, through a targeted structural integration design of an integrated energy storage chamber, takes into account the inherent advantages of sodium-ion solid-state batteries and solves the core problems of traditional energy storage systems such as "low space utilization, severe electromagnetic interference, poor maintenance convenience, and insufficient safety redundancy" through a structural integration logic of "functional zoning - component collaboration - system linkage".

[0053] I. Core Design Principles:

[0054] 1. Physical isolation and functional focus: The three-compartment separation design achieves physical isolation between the "energy storage core - power conversion - control center", avoiding mutual interference between the high temperature of the battery compartment, the strong electromagnetic field of the electrical compartment, and the precision electronic equipment of the control compartment, thus ensuring system stability.

[0055] 2. Modular and compatible design: The battery compartment has 10 battery packs with standardized interfaces, forming a "one-to-one" monitoring unit with the matching BMS. It can support single pack maintenance, expansion or replacement, and adapt to different energy storage capacity requirements.

[0056] 3. Separate control of energy flow and signal flow: The electrical compartment is responsible for power transmission and circuit protection, while the control compartment is responsible for signal processing and issuing scheduling commands, forming an architecture in which the "power layer and control layer" operate independently and respond in a coordinated manner, reducing the risk of fault propagation.

[0057] II. Key Integration Principles:

[0058] 1. Thermal Management Adaptation: In response to the low thermal runaway risk of sodium-ion solid-state batteries, the battery compartment adopts a natural heat dissipation + LED low-power lighting design to avoid additional heat sources. The limit switch is linked with the compartment door to realize "power off when the door is opened", further enhancing thermal safety protection.

[0059] 2. Electrical safety redundancy: The electrical compartment adopts a hierarchical protection design of "main power circuit breaker - PCS power circuit breaker", combined with busbar (low impedance current transmission), surge protector (overvoltage suppression), and grounding busbar (equipotential connection) to build a "three-level protection + double redundancy" circuit safety system, which is adapted to the charging and discharging characteristics of sodium salt solid-state batteries.

[0060] 3. Intelligent Collaborative Control: With EMS as the core, a closed-loop control logic is established, consisting of "BMS status acquisition - EMS decision scheduling - PCS execution response - UPS power supply guarantee", to achieve real-time matching of battery status and energy scheduling.

[0061] The three-compartment structure of this utility model will be described in detail below with reference to the accompanying drawings.

[0062] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a three-compartment sodium salt solid-state energy storage compartment 1, including an integrated compartment 10. The interior of the integrated compartment 10 is physically divided into three independent compartments: a battery compartment 11, an electrical compartment 12, and a control compartment 13. A compartment door 100 is provided on the front side of the integrated compartment 10 (e.g., ...). Figure 2 The cabin door 100 is equipped with a heat dissipation window 101.

[0063] In this embodiment, the battery compartment 11, electrical compartment 12, and control compartment 13 are arranged in a triangular pattern within the integrated compartment 10, with the battery compartment 11 on the left, the control compartment 13 on the upper right, and the electrical compartment 12 on the lower right. In other embodiments, the battery compartment 11, electrical compartment 12, and control compartment 13 are arranged linearly within the integrated compartment 10, for example, in a row or a column.

[0064] like Figure 3 As shown, the battery compartment 11 contains multiple sodium-ion solid-state battery packs 110, multiple battery management systems (BMS) 111, at least one low-power LED light 112, and a cut-off mechanism 113.

[0065] Specifically, in this embodiment, 10 sodium salt solid-state battery packs 110 are arranged in the left battery compartment 11. Each sodium salt solid-state battery pack 110 is connected to a battery management system 111, which is used to monitor the voltage, temperature, SOC (State of Charge) and SOH (State of Health) of each battery pack one-to-one, dynamically balance the energy between battery packs, avoid overcharging and over-discharging of individual cells, and extend the cycle life of the battery.

[0066] Two LED lights 112 are also installed inside the battery compartment 11. Figure 3 Only one is shown in the image) and two cutting mechanisms 113 ( Figure 1 and Figure 3 (Only one is shown in the figure). LED lighting 112 provides low-power lighting (power ≤10W, lifespan ≥50,000 hours) for in-cabin maintenance. Battery compartment 11 has an independent battery compartment door 114, and electrical compartment 12 and control compartment 13 also have independent doors (not shown in the figure), facilitating independent maintenance and operation of each compartment. The cut-off mechanism 113 is mechanically linked to the battery compartment door 114 to cut off the output power of the sodium salt solid-state battery pack 110 when the battery compartment door 114 is opened, eliminating the risk of electric shock during operation and maintenance and ensuring the safety of maintenance personnel.

[0067] The cutting-off mechanism 113 includes, for example, a DC contactor and a limit switch (not shown). The main contacts of the DC contactor are connected in series between the positive output terminal of the sodium-ion solid-state battery pack 110 and the positive terminal of the busbar 122. Each sodium-ion solid-state battery pack 110 may have one corresponding DC contactor, or multiple sodium-ion solid-state battery packs 110 may share one DC contactor. The limit switch is installed inside the door frame of the battery compartment door 114 and is mechanically linked to the battery compartment door 114. When the battery compartment door 114 is closed, the door presses against the limit switch, causing its normally open contacts to close; when the battery compartment door 114 is opened, the limit switch resets, and the contacts open. The contacts of the limit switch are connected in series in the coil power supply circuit of the DC contactor. The coil power supply is taken from an auxiliary power supply (such as a 24V DC bus).

[0068] The electrical compartment 12 houses a power storage converter (PCS) 120, a main power circuit breaker 121, a busbar 122, a PCS power circuit breaker 123, a PCS AC circuit breaker 124, and a surge protector 125. Multiple sodium-ion solid-state battery packs 110 are connected to the DC side of the power storage converter 120 via the busbar 122. The AC side of the power storage converter 120 is used to connect to the power grid or load. The main power circuit breaker 121 is connected in series in the circuit as primary protection.

[0069] Specifically, in this embodiment, the electrical compartment 12 is equipped with an energy storage converter 120, a main power circuit breaker 121, a PCS power circuit breaker 123, one positive and one negative busbar (not shown in the figure), a surge protector 125, and a grounding busbar (not shown in the figure). The busbar 122 includes a positive busbar, a negative busbar, and a grounding busbar.

[0070] The positive terminal of the sodium-ion solid-state battery pack 110 is connected to the positive busbar of busbar 122, and the negative terminal of the sodium-ion solid-state battery pack 110 is connected to the negative busbar of busbar 122. The positive and negative busbars (with a conductive cross-section ≥ 120 mm²) enable centralized current transmission from the sodium-ion solid-state battery pack 110, reducing line losses. The grounding busbar ensures continuous grounding of the entire device, protecting personnel and equipment safety.

[0071] A main power circuit breaker 121 is connected in series between the busbar 122 and the DC side of the energy storage converter 120, serving as a primary protection circuit to control the power supply to the entire unit. A PCS power circuit breaker 123 is connected in series between the main power circuit breaker 121 and the DC side of the energy storage converter 120, forming a secondary protection circuit to prevent the spread of local faults. The AC side of the energy storage converter 120 is connected to the AC bus via a PCS AC circuit breaker 124, which connects to the three-phase mains power 2 and / or local AC loads (not shown in the figure). When operating in grid-connected mode, the energy storage converter 120 performs bidirectional energy exchange with the three-phase mains power 2, completing the conversion between the battery pack's DC power and the grid's AC power; when operating off-grid, the energy storage converter 120 directly supplies power to the local AC load. The energy storage converter 120 has a conversion efficiency of ≥98% and supports active / reactive power regulation.

[0072] One end of surge protector 125 is connected to the AC bus between the AC side of energy storage converter 120 and the three-phase mains power 2, and the other end is connected to the grounding copper bus. The maximum discharge current Imax of surge protector 125 is ≥20kA, used to suppress overvoltage on the grid side.

[0073] The control compartment 13 houses an energy management system (EMS) 130, an uninterruptible power supply (UPS) 131, an industrial / commercial energy storage terminal (EMU) 132, a touch control panel 133, and a low-voltage circuit breaker 134. The EMS 130 is communicatively connected to the battery management system 111, the energy storage converter 120, and the industrial / commercial energy storage terminal 132, receiving battery status data and industrial / commercial power consumption data and issuing charging and discharging strategies. The UPS 131 is connected to the EMS 130, the touch control panel 133, and the industrial / commercial energy storage terminal 132, maintaining power supply during mains power outages. The touch control panel 133 is connected to both the EMS 130 and the UPS 131.

[0074] Specifically, in this embodiment, the control cabin 13 includes an uninterruptible power supply (UPS) 131, a touch control screen 133, several low-voltage circuit breakers 134, an industrial / commercial energy storage terminal 132, and an energy management system 130. The energy management system 130 acts as the "brain," receiving battery status data from the BMS111 and industrial / commercial power consumption data from the EMU132, generating charging and discharging strategies through optimization algorithms, and issuing commands to the PCS120 for execution. The industrial / commercial energy storage terminal 132 enables data interaction with external industrial / commercial power distribution systems, supporting demand response, peak-valley arbitrage, and other scenario linkages. The touch control screen 133 provides a local human-machine interface, supporting parameter setting, status viewing, and fault diagnosis. The low-voltage circuit breakers 134 provide overload and short-circuit protection for the control and communication circuits. The UPS 131 (output power ≥ 1kVA) quickly switches over when the main power is interrupted, ensuring uninterrupted operation of core control devices such as the EMS130, BMS111, and touch control screen 133, preventing the energy storage system from going out of control.

[0075] In this embodiment, there are several low-voltage circuit breakers 134. Several low-voltage circuit breakers 134 form a low-voltage circuit breaker group, such as including multiple miniature circuit breakers (MCBs), which are all installed side by side on the mounting rails in the control compartment 13. Their input terminals are electrically connected to the output terminals of the uninterruptible power supply 131 and receive 220V AC power.

[0076] For example, the outgoing terminals of each low-voltage circuit breaker are electrically connected to the core control equipment inside the cabin, specifically including: a first low-voltage circuit breaker, whose outgoing terminal is connected to the power input terminal of the energy management system; a second low-voltage circuit breaker, whose outgoing terminal is connected to the power input terminal of the touch control screen; a third low-voltage circuit breaker, whose outgoing terminal is connected to the power input terminal of the industrial and commercial energy storage terminal (EMU); and a fourth low-voltage circuit breaker, whose outgoing terminal is connected to the power terminal of the communication gateway of the battery management system (BMS).

[0077] The low-voltage circuit breaker 134, for example, is an intelligent miniature circuit breaker with a built-in RS485 communication module. It connects to the EMS via shielded twisted-pair cable to achieve real-time monitoring of voltage, current, power, and temperature of each circuit, and supports remote opening and closing control. The grounding terminals of all control equipment are connected to the grounding copper busbar in the control compartment via yellow-green wire to form an equipotential bond.

[0078] In the implementation of this utility model, the solution follows a four-step logic of "component standardization → cabin integration → system linkage → verification scenario" to ensure the reliability and replicability of the integration process, as shown in Table 1.
