A multi-bin coordinated charging and discharging intelligent regulation and control device of a new energy power station energy storage system

Abstract

This invention relates to the field of energy storage technology for new energy power plants, and discloses a multi-compartment coordinated charging and discharging intelligent control device for a new energy power plant energy storage system. The device includes a container body, multiple battery clusters and a DC power control cabinet installed on its inner wall. The energy storage EMS energy management system host sends control commands to drive the drive module to synchronously energize electromagnetic coil one and electromagnetic coil two to generate a directional magnetic field. Electromagnetic coil one, in conjunction with a magnetically conductive shell, magnetizes the iron core. The iron core magnetically attracts the I-shaped armature to compress the spring one, which slides downward along the inner wall of the connecting cavity and pulls the telescopic partition to divide the upper part of the connecting cavity into independent positive and negative magnetorheological chambers that are not connected. The magnetorheological fluid in the liquid chamber flows into the corresponding chamber and, under the action of the magnetic field of electromagnetic coil two, transforms from a liquid state into a rigid solid-like state and forms a dense conductive chain, thereby forming a conductive path to ensure that the battery clusters can be independently switched on and off and coordinated across multiple compartments.

Description

[0002] With the large-scale grid connection of new energy power generation such as photovoltaic and wind power, the problems of intermittency and volatility in their output have become increasingly prominent. Multi-warehouse collaborative containerized energy storage power stations have become the core equipment for smoothing grid fluctuations and achieving peak shaving and valley filling, while intelligent charging and discharging control devices are key components to ensure the efficient, safe and stable operation of energy storage systems.

[0003] Existing multi-compartment coordinated charging and discharging intelligent control devices typically use multiple battery clusters to share a single on / off mechanism, which cannot achieve independent switching and coordinated scheduling. This easily leads to circulating currents and short-board effects, exacerbating battery cluster losses, shortening the overall lifespan, and potentially causing frequent short circuits.

[0019] The present invention has the following beneficial effects:

[0020] 1. The multi-compartment coordinated charging and discharging intelligent control device of the new energy power station energy storage system drives the drive module to synchronously energize electromagnetic coil one and electromagnetic coil two through the control command issued by the host of the energy storage EMS energy management system to generate a directional magnetic field. Among them, electromagnetic coil one, together with the magnetic shell, magnetizes the iron core. The iron core magnetically attracts the I-shaped armature to compress the spring one, slides down along the inner wall of the connecting cavity, and pulls the telescopic partition to divide the upper part of the connecting cavity into independent positive and negative magnetorheological chambers that are not connected. The magnetorheological fluid in the liquid chamber flows into the corresponding chamber and transforms from liquid to rigid solid under the action of the magnetic field of electromagnetic coil two, forming a dense conductive chain, which in turn forms a conductive path, ensuring that the battery cluster can achieve independent switching and multi-compartment coordinated scheduling.

[0021] 2. The multi-compartment coordinated charging and discharging intelligent control device of this new energy power station energy storage system uses the magnetic attraction of the I-shaped armature as a driving force to drive the inclined end of the copper rod to twist around the fulcrum axis to avoid collision, and simultaneously compress the torsion spring to store energy. After the I-shaped armature completely passes the end of the copper rod, the copper rod is driven to quickly reset with the elastic torque of the torsion spring. During this process, the copper rod is stuck on the top of the I-shaped armature, and the end face is completely in contact with the magnetorheological fluid solidified in the connecting cavity, forming a closed-loop conductive path from the corresponding positive and negative copper busbars of the battery cluster to the conductor and the DC control cabinet. This achieves stable charging and discharging transmission with low impedance and high current, thereby avoiding the phenomenon of conductor detachment or circuit disconnection caused by charging and discharging current impact and equipment vibration.

[0022] 3. The multi-compartment collaborative charging and discharging intelligent control device of this new energy power station energy storage system achieves full coverage collection of flue gas from the top of the battery cluster by using a cone-shaped gas guide hood with a large opening facing downwards. The gas concentration detector on the inner wall monitors the flue gas concentration in real time and uploads a preliminary early warning signal. The collected flue gas is sent into the quantitative chamber through gas pipe one, centrifuge shell, and gas pipe two. Then, an inert carrier gas is drawn by a diaphragm gas pump to carry the flue gas sample and send it into a temperature-controlled hollow quartz tube. The carbon molecular sieve stationary phase coating on the inner wall fully adsorbs and separates the mixed flue gas. After identifying fault gases such as hydrogen and carbon monoxide, they are sent to the TCD detector for qualitative and quantitative analysis, thereby realizing the direct determination of internal faults in the battery cluster. This avoids the risk of explosion and poisoning caused by faulty flue gas remaining in the container cavity for a long time, and eliminates the problems of false alarms and missed alarms caused by indirect voltage and temperature diagnosis in traditional devices.

[0023] 4. The multi-compartment collaborative charging and discharging intelligent control device of this new energy power station energy storage system conducts the overheated heat of the positive and negative copper busbars of the battery cluster through a crossbar made of aluminum nitride ceramic. This drives the spiral titanium-nickel shape memory alloy wire to rapidly contract and deform after reaching the phase change temperature. This causes the guide block to slide smoothly along the guide rod and simultaneously pulls the L-shaped connecting rod and piston plate to move directionally within the cylinder. During this process, the movement of the piston plate creates a negative pressure in the inner cavity of the cylinder. The negative pressure pushes open the spring plate and opens the cross groove, simultaneously drawing the magnetorheological fluid from the independent positive and negative chambers into the cylinder through two pipes. This significantly reduces the conductive thickness of the magnetorheological fluid, so that it can only form sparse and short conductive chains under the action of the magnetic field. The circuit resistance increases exponentially, thereby preventing the spread and expansion of overcurrent and overheating faults in a single battery cluster. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1 - Figure 11 A multi-compartment coordinated charging and discharging intelligent control device for a new energy power station energy storage system includes a container body 1, a container body 1 and multiple battery clusters 2 and a DC power control cabinet 16 installed on its inner wall, multiple I-shaped shells 6 and cabinets 10 corresponding one-to-one with the battery clusters 2 installed on the inner wall of the container body 1, a safety diagnostic component 5 is provided on the top of the container body 1, and positive copper busbars 3 and negative copper busbars 4 are respectively installed on the outer wall of the battery clusters 2.

[0042] The inner cavity of the I-shaped housing 6 is provided with a charging and discharging component 7 and a conductive component 8, and the outer wall of the I-shaped housing 6 is provided with an adjustment component 9;

[0043] The inner wall of the cabinet 10 is equipped with an energy storage EMS energy management system host 12, an AVC control substation 13, a drive module 14 and a TCD detector 15, and the outer wall of the cabinet 10 is equipped with an operation panel 11.

[0044] The filling and discharging assembly 7 includes a liquid chamber 71, a control chamber 72, and a connecting chamber 73. The inner wall of the control chamber 72 is provided with an electromagnetic coil 74, a magnetic shell 75, and an iron core 76. The inner wall of the connecting chamber 73 is provided with a spring 77 and an I-shaped armature 78. The top of the I-shaped armature 78 is provided with a telescopic partition 79. The inner wall of the connecting chamber 73 is provided with an electromagnetic coil 710.

[0045] In the above structure, by integrating the charging / discharging assembly 7, the conductive assembly 8, and the regulating assembly 9 into the I-shaped housing 6 and setting them one-to-one with the battery clusters 2, a modular multi-group independent control unit is formed. The main unit 12 of the energy storage EMS energy management system controls the electromagnetic coil 74 and electromagnetic coil 710 in the charging / discharging assembly 7 according to the real-time status of each battery cluster 2 through the drive module 14, thereby realizing independent switching control of each battery cluster 2.

[0047] In a preferred embodiment: the air guide hood 51, centrifuge shell 54, metering chamber 57, temperature control box 59, carrier gas box 510, and diaphragm air pump 512 are respectively installed on the top of the container body 1. The air guide hood 51 is conical, and the large-diameter end of the air guide hood 51 faces the top of the corresponding battery cluster 2. One end of the first air pipe 52 is connected to the small-diameter end of the air guide hood 51, and the other end of the first air pipe 52 is connected to the air inlet end of the centrifuge shell 54. The first solenoid valve 53, motor 55, temperature control box 59, diaphragm air pump 512, flow valve 514, second solenoid valve 515, and gas concentration detector 517 are respectively electrically connected to the main unit 12 of the energy storage EMS energy management system. The number of air guide hood 51, gas concentration detector 517, first air pipe 52, and first solenoid valve 53 are the same as the number of battery clusters 2, and they correspond one-to-one. The centrifuge fan blade 516 is located in the inner cavity of the centrifuge shell 54, and one end of the second air pipe 56 is connected to the centrifuge shell 54. The air outlet of the casing 54 is connected, and the other end of the second air pipe 56 is connected to the air inlet of the metering chamber 57. One end of the fifth air pipe 513 is connected to the air outlet of the diaphragm pump 512, and the other end of the fifth air pipe 513 is connected to the air inlet of the metering chamber 57. One end of the fourth air pipe 511 is connected to the air outlet of the carrier gas box 510, and the other end of the fourth air pipe 511 is connected to the air inlet of the diaphragm pump 512. One end of the third air pipe 58 is connected to the air outlet of the metering chamber 57. The air pipes are connected at the air end, and the other end of the air pipe 3 58 passes through the inner cavity of the temperature control box 59 and is connected to the air inlet of the hollow quartz tube 518. One end of the air pipe 6 519 passes through the inner wall of the container body 1 and the temperature control box 59 and is connected to the air outlet of the hollow quartz tube 518. The other end of the air pipe 6 519 passes through the inner wall of the cabinet 10 and is connected to the air inlet of the TCD detector 15. The inner wall of the hollow quartz tube 518 is coated with a carbon molecular sieve stationary phase coating.

[0048] In the above structure, the gas guide hood 51, centrifuge shell 54, metering chamber 57, temperature control box 59, carrier gas box 510, and diaphragm air pump 512 are respectively installed on the top of the container body 1. This avoids occupying the energy storage installation space inside the container body 1, ensuring that the battery cluster 2 is neatly arranged and has smooth heat dissipation. At the same time, when the battery cluster 2 experiences internal short circuits, overheating, or other faults, it will release characteristic fumes such as hydrogen and carbon monoxide. The conical gas guide hood 51, with its large opening facing downwards, can then fully cover and collect the fumes. The gas concentration detector 517 on the inner wall monitors the fumes concentration in real time and uploads the signal to the energy storage EMS energy management system host 12 for initial warning. Simultaneously, the energy storage EMS energy management system host 12 opens the solenoid valve 53 and starts the motor 55 to drive the centrifuge fan blades 516 to rotate at high speed, generating negative pressure to draw the fumes into the centrifuge shell 54 through the gas pipe 52, and then through the gas pipe 512. 6. The sample is fed into the quantitative chamber 57 to complete quantitative sampling in sequence, avoiding prolonged retention of flue gas in the inner cavity of the container body 1. At the same time, the diaphragm air pump 512 draws inert gas from the carrier gas box 510 and sends it into the quantitative chamber 57 after the flow is stabilized by the flow valve 514. The inert gas carries the flue gas sample from the inner cavity of the quantitative chamber 57 into the hollow quartz tube 518 in the temperature control box 59. The temperature control box 59 maintains a constant temperature to ensure the separation effect. The carbon molecular sieve stationary phase coating on the inner wall of the hollow quartz tube 518 adsorbs and separates the mixed flue gas. After separating different characteristic gases one by one, they are sent to the TCD detector 15 through the gas pipe 6 519 to complete qualitative and quantitative detection. Finally, the fault signal is fed back to the host 12 of the main energy storage EMS energy management system to provide a basis for subsequent charge and discharge regulation and circuit protection. This is different from the traditional indirect diagnosis of voltage and temperature, realizing the direct determination of the fault of the battery cluster 2 and eliminating false alarms and missed alarms.

[0052] In the above structure, four sets of symmetrically distributed conductive components 8 are respectively connected to the positive copper busbar 3 and negative copper busbar 4 of the battery cluster 2 and the DC power control cabinet 16, thereby constructing a complete and stable charging and discharging conductive circuit. Under normal charging and discharging conditions, the I-shaped armature 78 slides downward along the inner wall of the connecting cavity 73 under the adsorption of the iron core 76. Its outer wall first contacts the inclined end of the copper rod 87, forcing the copper rod 87 to rotate downward ninety degrees around the fulcrum axis 85 and drive its torsion spring 86 to contract, so as to make enough space for the I-shaped armature 78 to move downward. At the same time, after the I-shaped armature 78 continues to move downward and completely passes the end position of the copper rod 87, the copper rod 87 loses the squeezing constraint and then resets under the elastic torsional reset action of the torsion spring 86, so that it is stuck in the... At the top of the I-shaped armature 78, due to its downward displacement, the magnetorheological fluid in its liquid cavity 71 will immediately enter the inner cavity of the connecting cavity 73. At this time, the inclined end of the copper rod 87 at the top of the I-shaped armature 78 will be in complete contact with the magnetorheological fluid entering the inner cavity of the connecting cavity 73. Subsequently, in conjunction with the conductive properties of the solidified magnetorheological fluid, auxiliary conductive conduction is formed. At the same time, the ball head installed at the end of the wire 88 always adheres to the outer wall of the copper rod 87 away from the inclined end. From the copper rod 87 to the wire 88, and then to the positive copper busbar 3 and the negative copper busbar 4 and the DC control cabinet 16, a continuous closed conductive transmission path is formed, which ensures the stable transmission of charging and discharging current. When a fault occurs, the control is cut off, or the circuit needs to be disconnected, the adsorption force of its iron core 76 is used to ensure the stable transmission of charging and discharging current. The I-shaped armature 78 disappears, and under the restoring force of the spring 77, it is pushed upward, forcibly pushing open the copper rod 87 and causing it to rotate upward ninety degrees to avoid it. This causes the I-shaped armature 78 to push the magnetorheological fluid at its top, and the magnetorheological fluid in the inner cavity of the connecting cavity 73 is pushed into the inner cavity of the liquid cavity 71, ultimately achieving disengagement from the inclined end of the copper rod 87, thus breaking the conductive path. The other end of the wire 88, which is connected to the terminals of the positive copper busbar 3 and the negative copper busbar 4, with a ball head, is inserted into the inner cavity of the matching groove 84. The ball head of the wire 88 first contacts the inclined end of the convex pin 89, causing the inclined end of the convex pin 89 to slide along the inner wall of the circular groove 83 under the pressure of the ball head, and driving the top... The second spring 810 is compressed until the ball head passes the inclined end of the convex pin 89, causing the convex pin 89 to be reset by the spring 810 and inserted into the inner cavity of the corresponding slot 811. Next, the two wires 88 corresponding to the DC control cabinet 16 are stably connected using the above synchronous operation, preventing the wires 88 from being disconnected due to conductive impact. When it is necessary to release the fixation, the energy storage EMS energy management system host 12 is pushed upwards, causing the push rod 812 to slide along the inner wall of the slide groove 84 and causing one side of the convex pin 89 to slide again along the inner wall of the circular groove 83, causing the second spring 810 to be compressed again until the convex pin 89 exits the inner cavity of the slot 811, thus releasing the lock formed on its wires 88.Then, simply pull the wire 88 out of the inner cavity of the circular slot 82, thus achieving convenient disassembly and reducing maintenance time.

[0053] In a preferred embodiment: the adjusting assembly 9 includes a crossbar 91 and a cylinder 97. A guide rod 92 is fixedly installed on the outer wall of the crossbar 91. A guide block 93 is slidably connected to the inner wall of the guide rod 92. A titanium-nickel shape memory alloy wire 94 is provided on the outer wall of the crossbar 91. A spring 95 is provided on the inner wall of the guide rod 92. One end of an L-shaped connecting rod 96 is fixedly installed on the outer wall of the guide block 93. A piston plate 910 is fixedly installed on the outer wall of the other end of the guide block 93. A pipe 98 is provided on the outer wall of the cylinder 97. A spring 99 is installed on the inner wall of the cylinder 97. An arc-shaped telescopic plate 912 and an arc-shaped telescopic plate 911 are respectively provided on the inner wall of the cylinder 97. A cross groove 913 is opened on the outer wall of the spring 99.

[0054] In a preferred embodiment: one end of the crossbar 91 is connected to the outer wall screw of the positive copper busbar 3, and the other end of the crossbar 91 is connected to the outer wall screw of the negative copper busbar 4. There are two springs 95, symmetrically arranged with respect to a titanium-nickel shape memory alloy wire 94 as the center. One end of each spring 95 overlaps with the outer wall of the guide block 93, and the other end overlaps with the outer wall of the crossbar 91. The titanium-nickel shape memory alloy wire 94 is spiral-shaped, with one end overlapping with the outer wall of the crossbar 91 and the other end overlapping with the outer wall of the guide block 93. The piston plate 910 is located within the inner cavity of the cylinder 97, and the piston plate 910... The outer wall of the stopper plate 910 is slidably fitted against the inner wall of the cylinder 97. The cylinder 97 is installed on the outer wall of the I-shaped outer shell 6. There are two pipes 98, one end of which is connected to the liquid outlet of the connecting cavity 73, and the other end of which is connected to the liquid inlet of the cylinder 97. One end of the arc-shaped telescopic plate 912 is connected and fixed to the side wall of the piston plate 910, and the other end of the arc-shaped telescopic plate 912 is connected and fixed to the inner wall of the cylinder 97. One end of the arc-shaped telescopic plate 911 is connected and fixed to the side wall of the piston plate 910, and the other end of the arc-shaped telescopic plate 911 is connected and fixed to the inner wall of the cylinder 97. The crossbar 91 is made of aluminum nitride ceramic.

[0055] In the above structure, a crossbar 91 made of aluminum nitride ceramic connects the positive copper busbar 3 and the negative copper busbar 4. Utilizing its high thermal conductivity and strong insulation properties, it quickly conducts heat generated by overcurrent and overheating between the positive and negative copper busbars 3 and 4, while eliminating the risk of short circuits. Under normal operating conditions, the charging and discharging temperature of the battery cluster 2 is stable. The titanium-nickel shape memory alloy wire 94 remains relaxed, allowing its guide block 93 to be fixed in the initial position in the middle of the guide rod 92 under the elastic force of the springs 95 on both sides. This keeps the piston plate 910 stationary at a fixed point inside the cylinder 97. The magnetorheological fluid in the liquid chamber 71 and the connecting chamber 73 is filled and solidifies under the action of a magnetic field to form a complete conductive chain, stabilizing the circuit resistance and ensuring stable charging and discharging. When the current is normal, if the battery cluster 2 experiences overcurrent or an internal fault, causing a sudden temperature rise in the positive copper busbar 3 and negative copper busbar 4, the heat is rapidly transferred through the crossbar 91 to the titanium-nickel shape memory alloy wire 94. Upon reaching the phase change temperature, the wire rapidly contracts, sequentially pulling the guide block 93 along the guide rod 92. Simultaneously, the spring 95 is compressed, causing the L-shaped connecting rod 96 and piston plate 910 to move synchronously. As the piston plate 910 slides, a negative pressure is generated inside the cylinder 97. Since the cross groove 913 on the spring 99 penetrates its inner wall, it is normally closed. When the cylinder 97 slides, the negative pressure causes the spring 99 to deform, opening the cross groove 913 and allowing the connecting cavity 73 to open. Part of the magnetorheological fluid is drawn out through pipe 98 into cylinder 97, reducing the magnetorheological fluid level and conductive thickness in connecting cavity 73, thus decreasing the volume of magnetorheological fluid filling in connecting cavity 73. This reduces the cross-sectional area of ​​the solid conductive chain that can be formed under the same magnetic field strength. According to the resistance law R=ρL / S, with the resistivity ρ and conductive length L remaining essentially constant, the decrease in the conductive cross-sectional area S leads to a sharp increase in the loop resistance R, thereby achieving the purpose of current limiting and voltage reduction. Since there are two pipes 98, each pipe 98 corresponds to a positive magnetorheological chamber separated by telescopic partition 79 within the inner cavity of connecting cavity 73. The magnetorheological fluid in the positive and negative magnetorheological chambers enters the inner cavity of the cylinder 97 together with the negative magnetorheological chamber, avoiding the phenomenon of high positive voltage and low negative voltage. Secondly, when the piston plate 910 slides, it will drive the arc-shaped telescopic plate 912 on one side to compress and the arc-shaped telescopic plate 911 on the other side to stretch, so as to keep the cylinder 97 sealed and prevent the magnetorheological fluid from leaking. After the temperature drops to the normal range, the titanium-nickel shape memory alloy wire 94 will be extended and reset by the rebound of the two springs 95. The springs 95 will push the guide block 93 and the piston plate 910 back to their original positions, so that the magnetorheological fluid flows back to the inner cavity of the positive copper busbar 3, thereby realizing the normal conduction of the circuit.

[0056] In a preferred embodiment: the liquid cavity 71, the control cavity 72 and the connecting cavity 73 are respectively formed on the inner wall of the I-shaped housing 6. The I-shaped housing 6 is made of engineering plastic. One end of the connecting cavity 73 is connected to the inner wall of the liquid cavity 71, and the other end of the connecting cavity 73 is connected to the inner cavity of the control cavity 72.

[0057] In the above structure, by using engineering plastic to make the I-shaped outer shell 6, its excellent insulation performance and mechanical strength are utilized to ensure that the charging and discharging assembly 7 is electrically isolated from the external structural components during operation. The liquid chamber 71 serves as the storage chamber for the magnetorheological fluid. The magnetorheological fluid filled in its inner cavity undergoes a reversible phase transition under the action of the magnetic field generated by the electromagnetic coil 74, realizing the conversion from liquid to a solid-like state. At the same time, one end of the connecting cavity 73 is connected to the liquid chamber 71, and the other end is connected to the control cavity 72, forming a complete channel for the magnetic circuit and the liquid circuit. When the I-shaped armature 78 slides in the connecting cavity 73, the inner cavity of its connecting cavity 73 is divided into two chambers by the stretching of the telescopic partition 79, thereby preventing its positive and negative poles from contacting the magnetorheological fluid in the same chamber.

[0058] In a preferred embodiment: the inner cavity of the liquid chamber 71 is filled with magnetorheological fluid; an electromagnetic coil 74 is sleeved on the outer wall of the magnetically conductive outer shell 75 and is electrically connected to the drive module 14; the magnetically conductive outer shell 75 is sleeved on the outer wall of the iron core 76; one end of the iron core 76 is mounted on the inner wall of the control chamber 72, and the other end of the iron core 76 is correspondingly positioned at the bottom of the I-shaped armature 78; a spring 77 is located between the bottom of the I-shaped armature 78 and the top of the iron core 76, and the spring 77... The end of the spring 77 overlaps with the bottom of the I-shaped armature 78, and the other end of the spring 77 overlaps with the inner wall of the connecting cavity 73. The outer wall of the I-shaped armature 78 is slidably fitted against the inner wall of the connecting cavity 73. One end of the telescopic partition 79 is connected and fixed to the top opening of the connecting cavity 73, and the other end of the connecting cavity 73 is connected and fixed to the top of the I-shaped armature 78. The second electromagnetic coil 710 is electrically connected to the drive module 14, and the drive module 14 is electrically connected to the main unit 12 of the energy storage EMS energy management system.

[0059] In the above structure, the main unit 12 of the energy storage EMS energy management system sends control commands to the drive module 14, causing the drive module 14 to output corresponding currents to the electromagnetic coil 74 and the electromagnetic coil 710 according to the commands. When the main circuit needs to be connected, the electromagnetic coil 710 is energized to generate a magnetic field, which is conducted to the iron core 76 through the magnetic shell 75. After the iron core 76 is magnetized, it generates an electromagnetic attraction force, which attracts the I-shaped armature 78 to slide downward along the inner wall of the connecting cavity 73 and compress the bottom iron core 76. At the same time, due to the downward displacement of the I-shaped armature 78, the telescopic partition 79 at the top of it will be stretched. This stretching will divide the space at the top of the I-shaped armature 78 into two chambers, allowing the magnetorheological fluid in the liquid chamber 71 to enter these two chambers. This achieves positive and negative pole separation conduction to avoid safety hazards caused by conductive connection. Secondly, the electromagnetic coil 74 is energized and acts on the two chambers entering the connecting cavity 73. The magnetorheological fluid causes the carbonyl iron particles in it to align along the magnetic field direction to form a dense conductive chain. The magnetorheological fluid is transformed into a solid-like rigid body with a yield strength ≥30MPa. At the same time, as the I-shaped armature 78 slides down, its top pushes the conductive component 8 to establish mechanical contact, forming a low-resistance conductive path with the solidified magnetorheological fluid, thus realizing the main circuit conduction. When it is necessary to disconnect the circuit, its electromagnetic coil 1 74 and electromagnetic coil 2 710 are de-energized in sequence, causing the iron core 76 to be demagnetized. Then, the I-shaped armature 78 is reset upward by the rebound of the charging and discharging component 7. At the same time, when the I-shaped armature 78 is reset upward, it also drives the telescopic partition 79 on its top to change from a stretched state to a compressed state, so that the liquid magnetorheological fluid is pushed back into the inner cavity of the container body 1 and disconnected from the conductive component 8. The entire process is uniformly scheduled by the host 12 of the energy storage EMS energy management system to ensure the coordinated charging and discharging actions of each battery cluster 2.

[0060] In a preferred embodiment: the energy storage EMS energy management system host 12 is electrically connected to the AVC control substation 13, the DC power control cabinet 16 is electrically connected to the energy storage EMS energy management system host 12, the I-shaped housing 6, the charging and discharging assembly 7, the conductive assembly 8 and the regulating assembly 9 are regarded as a group of active components, and the number of these active components is adapted to the number of battery clusters 2, positive copper busbars 3 and negative copper busbars 4;

[0061] In the above structure, the I-shaped housing 6, charging and discharging assembly 7, conductive assembly 8, and regulating assembly 9 are considered as a group of moving components. The number of these moving components is adapted to the number of battery clusters 2, positive copper busbars 3, and negative copper busbars 4, thereby achieving modular expansion of multi-battery cluster 2 control. Simultaneously, the energy storage EMS energy management system host 12 is electrically connected to the AVC control substation 13, enabling it to acquire real-time grid voltage, frequency, and other parameters. Combined with the SOC, SOH, temperature, and other status information of each battery cluster 2, the optimal power allocation scheme is calculated through a multi-objective optimization algorithm. Furthermore, the DC control cabinet 16 and the energy storage EMS energy tube... The host 12 of the energy management system is electrically connected to receive power allocation commands and execute corresponding charging and discharging controls. When a battery cluster 2 needs to be put into operation, the host 12 of the energy storage EMS energy management system controls the charging and discharging components 7 of the corresponding active component through the drive module 14 to establish a conductive path between the battery cluster 2 and the DC power control cabinet 16. When it is necessary to disconnect, the charging and discharging components 7 are controlled to disconnect the path. Through the independent control and coordinated scheduling of each active component, the charging and discharging management of multiple battery clusters 2 is realized, eliminating the circulating current and short-board effect generated during the charging and discharging process of traditional devices, and improving the overall charging and discharging efficiency, safety and service life.

[0062] Working principle: First, the entire device is used to coordinate the charging and discharging of multiple battery clusters 2 in its new energy power station energy storage system. It receives grid dispatch commands or battery cluster 2 charging and discharging demand commands through the energy storage EMS energy management system host 12. Combining the SOC, SOH, and temperature data of each battery cluster 2, it generates an optimal power allocation scheme through a multi-objective optimization algorithm and sends conduction control commands to the corresponding drive module 14 of the battery cluster 2. Upon receiving the command, the drive module 14 synchronously outputs an adaptive current to the electromagnetic coil 74 and electromagnetic coil 710 of the charging and discharging component 7. After being energized, electromagnetic coil 74 generates a directional magnetic field, which is converged and conducted to the iron core 76 through the magnetically conductive outer shell 75, magnetizing the iron core 76 and generating electromagnetic attraction. Under the action of electromagnetic attraction, the I-shaped armature 78 compresses the bottom iron core 76 and slides downwards along the inner wall of the connecting cavity 73, causing the top telescopic partition 79 to stretch synchronously, connecting the... The upper space of cavity 73 is divided into two independent magnetorheological chambers, one for positive poles and one for negative poles, to avoid short circuits caused by the conduction of magnetorheological fluid between the positive and negative poles. During the downward movement of the I-shaped armature 78, its outer wall first squeezes the inclined end of the copper rod 87, forcing the copper rod 87 to rotate downwards by 90 degrees around the fulcrum axis 85, and simultaneously driving the torsion spring 86 to twist and store force, making enough space for the downward movement of the I-shaped armature 78. After the I-shaped armature 78 continues to move downwards and completely passes the end of the copper rod 87, the copper rod 87 loses the constraint of the squeezing force and rebounds under the elastic torsional reset action of the torsion spring 86, blocking the top position of the I-shaped armature 78. At the same time, the magnetorheological fluid in the liquid cavity 71 is subjected to gravity and pressure and enters the two chambers separated by the telescopic partition 79. The magnetic field generated by the electromagnetic coil 710 acts on the magnetorheological fluid, causing the carbonyl iron particles inside to be closely arranged along the direction of the magnetic field, forming a dense conductive chain, and the magnetorheological fluid is transformed into a high yield strength solid.The ball end of the wire 88 always adheres to the outer wall of the copper rod 87 away from the inclined end. Combined with the contact between the copper rod 87 and the magnetorheological fluid, a complete closed conductive path is sequentially constructed from the positive copper busbar 3 of the battery cluster 2, the negative copper busbar 4, to the DC control cabinet 16. The other end of the wire 88, which connects to the terminals of the positive and negative copper busbars 3 and 4, has a ball end inserted into the inner cavity of the corresponding groove 84. This causes the ball end of the wire 88 to first contact the inclined end of the convex pin 89. Under the pressure of the ball's spherical surface, the inclined end of the convex pin 89 slides along the inner wall of the second circular groove 83, compressing the second spring 810 at the top. This continues until the ball passes the inclined end of the convex pin 89, at which point the convex pin 89 is reset by the spring 810 and inserted into the inner cavity of the corresponding slot 811. Secondly, the two wires 88 corresponding to the DC power control cabinet 16 are stably connected by the above-mentioned synchronous operation to avoid the wires 88 from being disconnected from the conductive circuit due to conductive impact. When it is necessary to release the fixation, the main unit 12 of the energy storage EMS energy management system is pushed upward, so that the push rod 812 slides along the inner wall of the slide groove 84 and drives one side of the convex pin 89 to slide along the inner wall of the circular groove 83 again, and drives the spring 810 to be compressed again until the convex pin 89 exits the inner cavity of the slot 811, thereby releasing the lock formed on its wires 88. Then, the wires 88 can be pulled out from the inner cavity of the circular groove 82, realizing the conduction of the charging and discharging circuit of the corresponding battery cluster 2. Multiple battery clusters 2 are connected synchronously or stepwise according to the scheduling command to complete the multi-compartment coordinated charging and discharging.

[0063] During charging and discharging, the main unit 12 of the energy storage EMS energy management system continuously calibrates the grid parameters through the AVC control substation 13, adjusts the output current of the drive module 14 in real time, and controls the magnetic field strength of the electromagnetic coil, fine-tunes the solidification degree of the magnetorheological fluid and the circuit resistance to ensure stable charging and discharging current and voltage and avoid power fluctuations. At the same time, the regulating component 9 is in standby monitoring state, so that the crossbar 91 made of aluminum nitride ceramic can conduct the normal working heat of the positive copper busbar 3 and the negative copper busbar 4, so that the temperature of the titanium-nickel shape memory alloy wire 94 does not reach the phase change temperature and remains in a relaxed state. The guide block 93 is fixed under the support of the springs 95 on both sides, the piston plate 910 has no displacement, the level of the magnetorheological fluid is stable, and the circuit conduction state is not affected. If a battery cluster 2 has internal short circuit, overheating or other faults, it first releases characteristic fault fumes such as hydrogen and carbon monoxide, so that the conical gas guide hood 51 fully covers and collects the fumes, and the gas concentration detector 517 on the inner wall collects them. If the flue gas concentration exceeds the standard in real time, an early warning signal will be immediately uploaded to the host 12 of the energy storage EMS energy management system. After receiving the early warning, the host 12 of the energy storage EMS energy management system will open the solenoid valve 53 and start the motor 55 to drive the centrifugal fan blades 516 to rotate at high speed to generate negative pressure. The flue gas will be drawn into the centrifugal shell 54 through the first gas pipe 52 and then sent into the quantitative chamber 57 through the second gas pipe 56 to complete the quantitative sampling. At the same time, the diaphragm pump 512 will draw inert carrier gas from the carrier gas box 510 and send it into the quantitative chamber 57 after the flow is stabilized by the flow valve 514. This will allow the flue gas sample to enter the hollow quartz tube 518 in the temperature control box 59. The carbon molecular sieve stationary phase coating on the inner wall of the hollow quartz tube 518 will adsorb and separate the mixed flue gas. After separating the different characteristic gases one by one, they will be sent into the TCD detector 15 through the sixth gas pipe 519 to complete the qualitative and quantitative detection. This will determine the fault type and severity and feed back to the host 12 of the energy storage EMS energy management system.Simultaneously, if the fault is accompanied by a sudden temperature rise in the positive copper busbar 3 and the negative copper busbar 4, the heat is transferred to the titanium-nickel shape memory alloy wire 94 through the aluminum nitride ceramic crossbar 91, causing it to contract after reaching the phase transition temperature. This causes the guide block 93 to slide along the guide rod 92, compressing the spring 95 and simultaneously moving the piston plate 910. A negative pressure is generated inside the cylinder 97, and the spring 99 deforms, causing the cross groove 913 to open. This draws some of the magnetorheological fluid from the connecting cavity 73 into the cylinder 97 through the pipe 98, reducing the magnetorheological fluid level and conductive thickness. This results in only sparse conductive chains being formed under the influence of the magnetic field, thereby significantly increasing the circuit voltage. The system reduces voltage and current to suppress the spread of the fault. Simultaneously, the main unit 12 of the energy storage EMS management system issues a shutdown command. The drive module 14 cuts off the power supply to electromagnetic coils 74 and 710, demagnetizing the iron core 76 and causing it to lose its attractive force. Under the reset thrust of spring 77, the I-shaped armature 78 is pushed upwards, forcibly opening the copper rod 87 and causing it to rotate 90 degrees upwards to avoid the fault. The I-shaped armature 78 pushes the magnetorheological fluid in the chamber back to the liquid chamber 71. The copper rod 87 loses contact with the magnetorheological fluid, and the conductive circuit is quickly disconnected, achieving independent isolation of the faulty battery cluster 2 without affecting the normal charging and discharging of other battery clusters 2.
