Description

Technical Field

[0001] This invention relates to an immersion-type energy storage battery temperature control system, and more particularly to an energy storage battery temperature control system that separates multiple battery modules from a large equivalent of temperature-controlled liquid for rapid heat exchange. Background Technology

[0002] There are two existing temperature control technologies for energy storage systems. The first is to use gas to cool the energy storage system, and the second is to use liquid to cool the energy storage system. Among them, the traditional air cooling method uses natural air convection or forced air convection. However, air cooling efficiency has its limitations. Moreover, as the energy density of the energy storage system increases, the air flow channel will be severely compressed, making it impossible for the air-cooled energy storage system to provide effective temperature control.

[0003] In addition, traditional liquid cooling methods are divided into indirect heat dissipation technology with water-cooled plates or direct battery immersion technology. Water-cooled plate technology requires the addition of water-cooled plates and cooling liquid pipelines, thereby increasing the complexity and cost of the energy storage system. Direct battery immersion technology, on the other hand, immerses the battery cells directly in the coolant, eliminating the need for water-cooled plates and cooling liquid pipelines. However, this immersion method has very high requirements for the performance of the coolant, requiring a liquid with special conditions such as non-conductivity and non-flammability. This demand for expensive coolants will significantly increase the cost of the energy storage system.

[0004] Furthermore, in the event of thermal runaway, current energy storage systems typically use additional water sources, aerosols, or gases (FM-200, Novec 1230) located outside the energy storage system for fire suppression. However, constructing additional fire suppression equipment for the energy storage system not only significantly increases the cost of system construction but also cannot completely prevent the fire suppression equipment from malfunctioning or failing. Summary of the Invention

[0005] The main objective of this invention is to provide an energy storage battery temperature control system that prevents the battery module from directly contacting a high-equivalent temperature-controlled liquid. This eliminates the need for a sealed design for the battery module itself, significantly reducing the complexity and cost of battery module design. Furthermore, the high-equivalent temperature-controlled liquid provides stable ambient temperature control, improving the heat exchange effect of the battery module.

[0006] A secondary objective of this invention is that, in the event of thermal runaway in the energy storage battery temperature control system, a large equivalent of temperature control liquid can be used directly as a fire suppressant, eliminating the need for an additional fire suppression system design. The temperature control liquid can be directly used to immerse the battery module to prevent the propagation of thermal runaway.

[0007] Another objective of this invention is that the energy storage battery temperature control system adopts a closed liquid circulation design in conjunction with the vortex flow channel formed by multiple fins, which can easily and quickly remove heat from the battery module, which is a self-heating source, and achieve rapid cooling without the need for additional liquid cooling components.

[0008] Another objective of this invention is that the energy storage battery temperature control system adopts a separate design between the battery module and the temperature control liquid, so that the temperature control liquid does not need to consider special solutions such as non-conductive and corrosive solutions, but can be replaced by commonly available liquids such as refrigerant, pure water or rainwater. This makes it convenient for the energy storage battery temperature control system to replace or obtain the temperature control liquid, which can significantly reduce the operating cost of the energy storage battery temperature control system.

[0009] Another objective of this invention is that the storage system can replace the battery module with other hazardous materials that also require control for storage. In the event of a dangerous out-of-control situation, the liquid can be directly submerged in the storage module to prevent the out-of-control situation from escalating.

[0010] To achieve the aforementioned objective, the present invention provides an energy storage battery temperature control system, comprising a fluid storage cabinet, a plurality of battery modules, a temperature control module, and a temperature-controlled liquid. The fluid storage cabinet has a plurality of insertion ports and a plurality of storage compartments connected one-to-one with the plurality of insertion ports, such that the interior of the fluid storage cabinet is divided into a liquid circulation space and a plurality of compartment spaces not connected to the liquid circulation space.

[0011] The plurality of battery modules have a battery body and a closed plate connected to the battery body. The battery body is detachably inserted into one of the plurality of storage compartments such that the closed plate covers the insertion port and the battery body contacts all conductive walls inside the storage compartment.

[0012] The temperature control module has an input pipe and an output pipe connecting to the liquid circulation space, and a temperature controller is connected between the input pipe and the output pipe. The temperature-controlled liquid is injected into the fluid storage cabinet, so that the temperature-controlled liquid flows through the input pipe, the temperature controller, and the output pipe of the liquid circulation space.

[0013] The temperature-controlled liquid is heated by the temperature controller to reach a first temperature, and then heated in the fluid storage cabinet to reach a second temperature. Subsequently, the temperature-controlled liquid will re-enter the temperature controller for heat exchange to reach the first temperature.

[0014] In addition, the energy storage battery temperature control system further includes a circuit control module, which is installed on the surface of the fluid storage cabinet and has a control box and a plurality of conductive wires, wherein the plurality of conductive wires are used to connect the plurality of storage compartments and the control box in series with each other.

[0015] The fluid storage cabinet further includes a plurality of fins and a circulation pump. The plurality of fins are respectively disposed on the outer surface of the plurality of storage compartments to increase the heat dissipation area, and the circulation pump is installed in the liquid circulation space to change the flow rate of the temperature-controlled liquid.

[0016] In a preferred embodiment, the plurality of fins are arranged in the liquid circulation space to form a fluid channel, such that the temperature-controlled liquid can cooperate with the fluid channel and the circulation pump in the liquid circulation space to form a vortex flow.

[0017] A first portion of the plurality of fins is distributed between adjacent pairs of the plurality of storage compartments to form a plurality of supporting turbulence regions, a second portion of the plurality of fins is distributed on the side surface of the plurality of storage compartments to form a plurality of guiding turbulence regions, and the fluid channel is formed by alternating arrangement of the plurality of guiding turbulence regions and the plurality of supporting turbulence regions.

[0018] Furthermore, the energy storage battery temperature control system further includes a plurality of disruptive devices, each disposed in at least one of the storage compartment and the battery module. Each disruptive device can disrupt one of the conductive walls of the storage compartment, allowing the temperature-controlled liquid to flow from the liquid circulation space into the compartment space, thus contacting the battery module to suppress high-temperature thermal runaway. In a feasible embodiment, one conductive wall of the storage compartment may be formed with a liquid inlet by the disruptive device, allowing the compartment space to be completely submerged by the temperature-controlled liquid.

[0019] The following provides four feasible implementations of the destructive device. The first embodiment of the destructive device includes a cover disposed on the battery body and a weakened tank wall disposed on the storage compartment. When the battery body ejects electrolyte under abnormal cell conditions, the cover and the weakened tank wall will be melted through by the high temperature of the electrolyte, so that the conductive wall surface forms a liquid inlet opening. Subsequently, the temperature-controlled liquid enters the storage compartment through the liquid inlet opening.

[0020] The second type of the destructive device includes a spiked destructive element disposed on the battery body. The spiked destructive element has a plurality of oblique cones and a plurality of flow channels. The plurality of oblique cones and the plurality of flow channels are alternately arranged to form a cone with spikes. When the battery body ejects electrolyte in an abnormal cell condition, the spiked destructive element is pushed by the electrolyte to destroy the conductive wall. Subsequently, the temperature-controlled liquid will enter the storage chamber through the flow channels.

[0021] The third form of the destructive device includes a liquid inlet opening provided in the storage chamber and an isolation component that seals the liquid inlet opening. When the battery body ejects electrolyte in an abnormal cell condition, the isolation component is pushed by the electrolyte and separates from the liquid inlet opening. Subsequently, the temperature-controlled liquid will enter the storage chamber through the liquid inlet opening.

[0022] The fourth form of the sabotage device is installed inside the storage compartment. The sabotage device includes a puncture device and a sensor. The sensor and the puncture device are electrically connected to a control circuit, and the control circuit is electrically connected to the circulation pump. The control circuit can control the puncture device to sabotage the conductive wall of the storage compartment, and the circulation pump can be pressurized by the control circuit when the battery module malfunctions.

[0023] In addition, a liquid-proof tight ring is provided between the plurality of battery modules and the fluid storage cabinet. When the battery module is inserted into the storage compartment through the insertion port, the liquid-proof tight ring will be clamped between the closing plate and the fluid storage cabinet, so that the storage space is sealed into a sealed space, preventing the temperature-controlled liquid from overflowing from the insertion port after entering the storage space.

[0024] The present invention also provides a storage system comprising: a fluid storage cabinet, a plurality of storage modules, a temperature-controlled liquid, and a plurality of disruptive devices. The fluid storage cabinet has a plurality of insertion ports and a plurality of storage compartments connected one-to-one with the plurality of insertion ports, such that the interior of the fluid storage cabinet is divided into a liquid circulation space and a plurality of compartment spaces not connected to the liquid circulation space. The plurality of storage modules have a storage box and a closing plate connected to the storage box. The storage box is detachably inserted into one of the plurality of storage compartments, such that the closing plate covers the insertion port, and the storage box contacts a conductive wall inside the storage compartment. The storage box also has a receiving space inside. The temperature-controlled liquid is injected into the liquid circulation space of the fluid storage cabinet. Each disruptive device is disposed in at least one of the storage compartments and the storage modules, and the disruptive device can disrupt the conductive wall of the storage compartment, allowing the temperature-controlled liquid to flow from the liquid circulation space into the compartment space.

[0025] The storage system further includes a temperature control module, which has an input pipe and an output pipe to connect to the liquid circulation space, and a temperature controller is connected between the input pipe and the output pipe, so that the temperature-controlled liquid can flow through the liquid circulation space, the input pipe, the temperature controller and the output pipe for heat exchange.

[0026] The first feature of this invention is that it adopts a structure in which the temperature-controlled liquid and the battery module are independently separated, allowing the battery module to have direct and large-area contact with the temperature-controlled liquid tank. This can significantly improve the heat conduction effect between the battery module and the heat dissipation fluid. Furthermore, the outer side of the storage compartment has heat exchange fins that increase the contact area. The heat dissipation fluid in the temperature-controlled liquid tank can effectively remove the heat from multiple parallel battery modules, and the conduction efficiency is far higher than that of air cooling technology and water cooling plate indirect heat dissipation technology.

[0027] Secondly, the temperature-controlled liquid tank encloses the temperature-controlled liquid within the tank to facilitate rapid flow with the circulation pump. Since the specific heat of the temperature-controlled liquid is much greater than that of air, this invention can provide a uniform and stable ambient temperature, making it convenient to control the operating temperature of the battery module. Furthermore, the heat dissipation fluid flows evenly to the gap between each pair of storage compartments, allowing the battery modules to be arranged in a compact manner to the maximum extent, which is beneficial to increasing the energy density per unit volume.

[0028] Thirdly, the temperature control module can manage the temperature of the temperature-controlled liquid in the temperature-controlled liquid tank according to the temperature conditions. Furthermore, the larger the volume of temperature-controlled liquid inside the temperature-controlled liquid tank, the less it is affected by the individual temperature of the battery module, and it can effectively block heat transfer between multiple battery modules.

[0029] Fourth, when any battery module in the energy storage battery temperature control system experiences thermal runaway, a large amount of high-pressure gas will be ejected from the cell venting valve of the battery module. This gas ejection will directly damage the battery module's containment chamber or drive the destruction device to break the seal of the containment chamber, allowing the temperature control liquid to enter the storage chamber and completely submerge the thermally runaway battery module, effectively preventing the spread of thermal runaway.

[0030] Fifth, since the temperature control liquid and the battery module do not actually come into contact during the heat exchange process, the temperature control liquid can be a low-cost solution such as fluorinated compounds, fluorocarbons, or hydrocarbons, or an easily obtainable liquid such as refrigerant, clean water, or rainwater, which facilitates the maintenance of the energy storage battery temperature control system in remote areas.

Detailed Implementation

[0045] Please see Figures 1 to 3 As shown, the energy storage battery temperature control system of the present invention includes a fluid storage cabinet 1, a plurality of battery modules 2, a temperature control module 3, a temperature-controlled liquid 4, and a circuit control module 5. As shown, the fluid storage cabinet 1 forms a plurality of insertion ports 10 only along a forward direction, and each insertion port 10 extends a storage space 11 in parallel, so that the fluid storage cabinet 1 forms a plurality of storage compartments 12 arranged in a matrix and a liquid circulation space 13 not connected to the plurality of storage compartments 12.

[0046] And as Figure 1 As shown, the fluid storage cabinet 1 has a top filling opening 101, an upper liquid inlet opening 102, and a lower liquid outlet opening 103. All three openings—the filling opening 101, the liquid inlet opening 102, and the liquid outlet opening 103—are connected to the liquid circulation space 13. The filling opening 101 can be closed by a top cover 14, and the temperature-controlled liquid 4 can flow into the fluid storage cabinet 1 from the filling opening 101 when the top cover 14 is open.

[0047] Please see Figure 2 and Figure 3As shown, each battery module 2 can be detachably plugged into one of the plurality of storage compartments 12. The battery module 2 has a closing plate 20 and a battery body 21. The outer side of the closing plate 20 has a circuit template 201 and two electrical signal connectors 202. The size of the closing plate 20 is slightly larger than the insertion port 10, so that the closing plate 20 can cover the insertion port 10. The battery body 21 is connected to an inner side of the closing plate 20. The battery body 21 includes a battery box 211 and a plurality of battery cells 212 housed in the battery box. The plurality of battery cells 212 are connected in series with each other and electrically connected to the circuit template 201 and the two electrical signal connectors 202.

[0048] like Figure 2 As shown, the battery module 2 further has a liquid-proof tight ring 22. The inner diameter contour of the liquid-proof tight ring 22 matches the battery box 211, so that one end of the battery body 21 can be inserted into the liquid-proof tight ring 22, and the liquid-proof tight ring 22 can move to the other end of the battery body 21 to abut against the closing plate 20.

[0049] When the battery module 2 is inserted into the storage compartment 12 through the insertion port 10, the liquid-proof tight ring 22 will be clamped by the closing plate 20 and the fluid storage cabinet 1, so that the storage space 11 is sealed into a closed space; and the battery body 21 will contact all the conductive walls inside the storage compartment 12. In this embodiment, the battery body 21 will contact five conductive walls, namely the upper side, lower side, left side, right side and rear side, so that the heat generated by the battery body 21 can be dissipated through the five large-area conductive walls.

[0050] Please refer to the following: Figure 1 and Figure 2 As shown, the temperature control module 3 has a temperature controller 30, an input pipe 31, and an output pipe 32. The temperature controller 30 is installed on an outer surface of the fluid storage cabinet 1. The input pipe 31 is connected between the drain opening 103 and the temperature controller 30, and the output pipe 32 is connected between the inlet opening 102 and the temperature controller 30, so that the temperature control module 3 is connected to the liquid circulation space 13. In addition, the output pipe 32 has a drain pipe 321 that connects to the outside.

[0051] When the temperature-controlled liquid 4 is injected into the fluid storage tank 1 through the addition opening 101, the temperature-controlled liquid 4 will sequentially flow through the liquid circulation space 13, the input pipe 31, the temperature controller 30, and the output pipe 32. When the energy storage battery temperature control system of the present invention is operating, the temperature-controlled liquid 4 will be heat-exchanged by the temperature controller 30 to form a first temperature, and the temperature-controlled liquid 4 will be heat-exchanged in the fluid storage tank 1 to form a second temperature. Subsequently, the temperature-controlled liquid 4 will re-enter the temperature controller 30 for heat-exchanged temperature to form the first temperature.

[0052] In one feasible embodiment, the fluid storage cabinet 1 is installed in a normal environment, and the temperature controller 30 is configured as a cooler, so that the first temperature is a low-temperature state (4-10°C), and the temperature-controlled liquid 4, after passing through the fluid storage cabinet 1, will be changed from the low-temperature first temperature to a high-temperature second temperature (40-80°C). In another feasible embodiment, the fluid storage cabinet 1 is installed in a cold environment, and the temperature controller 30 is configured as a heater. In yet another feasible embodiment, the temperature controller 30 includes both a cooler and a heater, so that the temperature control module 3 can select to execute a heating or cooling program according to different environmental conditions.

[0053] Please see Figure 3 and Figure 4 As shown, the liquid circulation space 13 of the fluid storage cabinet 1 further includes a plurality of fins 15 and a circulation pump 16. The plurality of fins 15 are respectively disposed on the outer surface of the plurality of storage chambers 12 to increase the heat dissipation area. The circulation pump 16 is installed in an upper region of the liquid circulation space 13 to change the flow rate of the temperature-controlled liquid 4.

[0054] In a preferred embodiment, the plurality of fins 15 are arranged in a fluid channel in the liquid circulation space 13, such that the temperature-controlled liquid 4 can cooperate with the fluid channel and the circulation pump 16 in the liquid circulation space 13 to form a vortex flow.

[0055] like Figure 3 As shown, a first portion of the plurality of fins 15 is distributed between adjacent pairs of the plurality of storage chambers 12 to form a plurality of supporting turbulence regions A1, and a second portion of the plurality of fins 15 is distributed on the side surface of the plurality of storage chambers 12 to form a plurality of guiding turbulence regions A2. The fluid channel is formed by alternating arrangement of the plurality of guiding turbulence regions A2 and the plurality of supporting turbulence regions A1.

[0056] like Figure 5A and Figure 5BAs shown, each guiding turbulence region A2 includes a plurality of transverse fins 151 and a plurality of oblique fins 152. The temperature-controlled liquid 4 flows horizontally in the plurality of transverse fins 151. When the temperature-controlled liquid 4 flows through the plurality of oblique fins 152, the temperature-controlled liquid 4 will change from horizontal flow to oblique flow.

[0057] Please see Figure 6 As shown in the illustrated embodiment, the storage compartment 12 has a plurality of fins 15 on each of its five conductive walls (upper, lower, left, right, and rear). Therefore, the heat generated by the battery body 21 can be exchanged with the temperature-controlled liquid 4 not only through the conductive walls but also through the plurality of fins 15. However, this is only for illustrative purposes; the storage compartment 12 may also have the plurality of fins 15 arranged in at least one direction.

[0058] Please see Figure 7 As shown, the circuit control module 5 is installed in the fluid storage cabinet 1. The circuit control module 5 has a control box 50 and a plurality of conductive wires 51. The control box 50 and the temperature control module 3 are fixed on the same side of the fluid storage cabinet 1. Two of the plurality of conductive wires 51 are connected between the control box 50 and the electrical signal connector 202 of the battery module 2. The remaining parts of the plurality of conductive wires 51 are connected to the electrical signal connector 202 of every two battery modules 2, so that the control box 50 is electrically connected to the plurality of battery modules 2.

[0059] Please refer to the following: Figures 8A to 8D as well as Figure 9 As shown, the energy storage battery temperature control system further includes a plurality of disruptive devices 6. Each disruptive device 6 is disposed in at least one of the storage chamber 12 and the battery module 2, and the disruptive device 6 can disrupt one of the conductive walls of the storage chamber 12, allowing the temperature-controlled liquid 4 to flow from the liquid circulation space 13 into the chamber space 11, so that the temperature-controlled liquid 4 contacts the battery module 2 to suppress high-temperature thermal runaway. In a feasible embodiment, an inlet opening 60 is formed on one of the conductive walls of the storage chamber 12 by the disruptive device 6 (see Figure 6). Figure 9 This allows the warehouse space 11 to be completely submerged by the temperature-controlled liquid 4.

[0060] like Figure 8AIn the first feasible embodiment shown, the destruction device 6 includes a spiked destruction member 61 disposed on the battery body 21. The spiked destruction member 61 has a plurality of oblique cone portions 611 and a plurality of flow channels 612. The plurality of oblique cone portions 611 and the plurality of flow channels 612 are alternately arranged to form a cone with spikes 613. When the battery body 21 ejects electrolyte in an abnormal cell condition, the spiked destruction member 61 is pushed by the electrolyte to destroy the conductive wall surface, so that the conductive wall surface forms the liquid inlet opening 60. Subsequently, the temperature-controlled liquid 4 will enter the storage chamber 12 through the liquid inlet opening 60 and the flow channels.

[0061] like Figure 8B In the second feasible embodiment shown, the destruction device 6 includes a cover 62 disposed on the battery body 21 and a weakened tank wall 63 disposed on the storage chamber 12. When the battery body 21 ejects an electrolyte under abnormal cell conditions, the cover 62 and the weakened tank wall 63 will be melted through by the electrolyte at high temperature, so that the conductive wall surface forms the liquid inlet opening 60. Subsequently, the temperature-controlled liquid 4 enters the storage chamber 12 through the liquid inlet opening 60.

[0062] like Figure 8C In the third feasible embodiment shown, the tampering device 6 includes the liquid inlet opening 60 disposed in the storage chamber 12 and an isolation member 64 that closes the liquid inlet opening 60. When the battery body 21 ejects an electrolyte in an abnormal cell condition, the isolation member 64 is pushed by the electrolyte and separates from the liquid inlet opening 60. Subsequently, the temperature control liquid 4 will enter the storage chamber 12 through the liquid inlet opening 60.

[0063] like Figure 8D In the fourth feasible embodiment shown, the tampering device 6 is disposed inside the storage chamber 12 and includes a puncture device 65 and a sensor 66. The sensor 66 and the puncture device 65 are electrically connected to a control circuit (not shown), and the control circuit is electrically connected to the circulation pump 16. When the control circuit detects an abnormality in the battery module 2 through the sensor 66, the control circuit will activate the puncture device 65 and adjust the power of the circulation pump 16, so that the conductive wall of the storage chamber 12 is punctured by the puncture device 65 to form the liquid inlet opening 60. At the same time, the circulation pump 16 will pressurize to accelerate the entry of the temperature-controlled liquid 4 into the storage chamber 12 to suppress the thermal runaway of the battery module 2.

[0064] Please see Figure 10 and Figure 11The figure shows a second embodiment of the energy storage battery temperature control system of the present invention. The energy storage battery temperature control system includes: a fluid storage cabinet 1, a plurality of battery modules 2, a temperature control module 3, a temperature-controlled liquid 4 (not shown), and a circuit control module 5. The fluid storage cabinet 1 has a plurality of front insertion ports 10a and a plurality of rear insertion ports 10b along a forward direction and a backward direction, respectively. However, the plurality of front insertion ports 10a and the plurality of rear insertion ports 10b are located at different heights. The plurality of front insertion ports 10a and the plurality of rear insertion ports 10b extend parallel to each other to form a storage space 11, so that the fluid storage cabinet 1 forms a plurality of front storage compartments 12a and a plurality of rear storage compartments 12b arranged in a matrix, and a liquid circulation space 13 that is not connected to the plurality of front storage compartments 12a and the plurality of rear storage compartments 12b. As shown in the figure, there is a height difference between the plurality of front storage compartments 12a and the plurality of rear storage compartments 12b.

[0065] The fluid storage cabinet 1 also includes a plurality of fins 15 (not shown) and a circulation pump 16, but the functions of the plurality of fins 15 and the circulation pump 16 are the same as in the first embodiment; in addition, the functions of the temperature control module 3, the temperature-controlled liquid 4 and the circuit control module 5 are also the same as in the first embodiment, so they will not be described in detail here.

[0066] Please see Figure 12 As shown, due to the height difference between the plurality of front storage chambers 12a and the plurality of rear storage chambers 12b, when the temperature-controlled liquid 4 flows in the liquid circulation space 13, the temperature-controlled liquid 4 will be affected by the plurality of fins 15 (not shown), the circulation pump 16 and the height difference to form a vortex flow.

[0067] Please see Figure 13 As shown, the present invention provides a storage system for storing hazardous materials. The storage system includes: a fluid storage cabinet 1, a plurality of storage modules 7, a temperature-controlled liquid 4, and a plurality of destructive devices 6. The storage system differs from the energy storage battery temperature control system in three ways: first, the storage system does not require a circuit control module 5; second, the plug-in battery module 2 is replaced by a storage module 7; and third, the storage system must have the plurality of destructive devices 6. However, the temperature control module 3 is selectively assembled based on requirements. Therefore, in the absence of the temperature control module 3, the temperature-controlled liquid 4 is only stored in the fluid storage cabinet 1 for use as an immersion liquid.

[0068] As shown in the figure, the storage module 7 has a storage box 70 and a closing plate 71 connected to the storage box 70. The storage box 70 is detachably inserted into one of the plurality of storage compartments 12, such that the closing plate 71 covers the insertion port 10, and the storage box 70 will contact a conductive wall inside the storage compartment 12. The storage box 70 has a receiving space 701 inside, allowing at least one hazardous object 8 to be selectively placed into the receiving space 701 of the storage box 70. The structural forms of the other components, such as the fluid storage cabinet 1, temperature control module 3, heat dissipation liquid 4, and destructive device 6, are the same as those of the energy storage battery temperature control system, and will not be described in detail here.

[0069] The above description is illustrative only and not restrictive of the present invention. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims of the present invention, and all such modifications, variations or equivalents will fall within the protection scope of the present invention.
