Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, and in particular to an energy-saving and environmentally friendly energy storage device. Background Technology

[0002] An energy storage device is a device used to store electrical energy and release it when needed. It can not only achieve dynamic balance between power supply and demand, improve energy utilization efficiency, and enhance the stability of power grid operation, but also realize flexible scheduling and optimized allocation of energy in distributed energy systems. A typical energy storage device usually includes an energy storage cabinet, which contains multiple compactly arranged battery modules and is equipped with a battery cooling system, thermal management control unit, and control terminal.

[0003] With the rapid development of renewable energy, energy storage devices have shown significant advantages in their combined application with photovoltaic power generation systems. Photovoltaic power generation systems convert light energy into electrical energy through solar cell modules, which is a clean and renewable energy utilization method. However, since its power generation capacity depends on sunlight conditions, it has obvious intermittency and uncertainty. In order to solve this problem, energy storage devices work in tandem with photovoltaic systems. During the day, photovoltaic modules store electrical energy and release electrical energy at night, during cloudy or rainy weather, or during peak electricity consumption periods, thereby achieving a continuous and stable energy supply.

[0004] However, due to long-term use or aging, the internal chemical reaction stability of batteries in energy storage devices decreases, making them prone to generating excessive heat during charging and discharging. In addition, batteries often expand before heating up. This expansion not only affects the structural integrity of the battery but also exacerbates the local temperature rise, thus forming a vicious cycle. When battery heating and expansion interact, it may lead to a serious risk of thermal runaway, thereby affecting the safety and stability of the entire energy storage system. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides an energy-saving and environmentally friendly energy storage device.

[0006] The technical implementation of this invention is as follows: An energy-saving and environmentally friendly energy storage device includes a protective cabinet. Two pairs of fixed frames are installed inside the protective cabinet. Two of the fixed frames in each pair are symmetrically distributed vertically. Symmetrically distributed first sliding frames are slidably connected between the symmetrically distributed fixed frames. A spring is installed inside each fixed frame between the symmetrically distributed first sliding frames. A linear array of rotating cylinders is arranged between the symmetrically distributed first sliding frames. Each rotating cylinder is equipped with an X-shaped swing frame. A connecting member is slidably connected to the rotating cylinder. A fixed frame is fixed between two connecting members at the same height. Batteries are placed inside the fixed frame. A docking assembly is installed on each of the first sliding frames to connect the X-shaped swing frames on the same side. A monitoring assembly for monitoring adjacent batteries is installed on the fixed frame. An isolation assembly, in a linear array and matching the number of batteries, is installed outside the protective cabinet to isolate abnormal batteries. The cabinet door is equipped with a removal assembly for pushing out abnormal batteries.

[0007] More preferably, the protective cabinet has symmetrically distributed fixing plates fixed inside, the connectors are fitted with the corresponding fixing plates, and the fixing plates are used to guide the connectors on the same side.

[0008] More preferably, the docking assembly includes a first hook tail frame and a second hook tail frame distributed at equal intervals. The upper first hook tail frame is fixed to the corresponding first sliding frame, and the lower second hook tail frame is slidably connected to the corresponding first sliding frame. The remaining second hook tail frames and the first hook tail frames are respectively hinged to the upper and lower sides of the corresponding X-shaped swing frame. Both the second hook tail frames and the first hook tail frames are rotatably connected to hook tongues. Torsion springs are provided between the first hook tail frames and the corresponding hook tongues, and both the second hook tail frames and the first hook tail frames are slidably connected to locking pins. The locking pins are used to limit the movement of adjacent hook tongues. Tension springs are provided between the first hook tail frames and the corresponding locking pins, and adjacent hook tongues limit each other.

[0009] More preferably, the locking pin is fixed to an elastic plate, and two adjacent elastic plates limit each other.

[0010] More preferably, apart from the second hook tail frame that slides on the lower side of the first sliding frame and the first hook tail frame that is fixed to the upper side of the first sliding frame, the remaining first hook tail frames and second hook tail frames are provided with elastic rings on the side near the adjacent first sliding frame. All the elastic rings are used to restrict the corresponding first hook tail frame and the corresponding second hook tail frame to the first sliding frame.

[0011] More preferably, the symmetrically distributed fixing frames are jointly fixed to a first electric slide rail, the electric slider of the first electric slide rail is fixed to a second sliding frame, and the second sliding frame is fixed to the second hook tail frame located on the lower side.

[0012] More preferably, the monitoring component includes symmetrically distributed airbags, all of which are fixed to the fixed frame. The opposing sides of the symmetrically distributed airbags are in contact with adjacent batteries. The fixed frame is fixed to and connected to symmetrically distributed fixed tubes. The opposing sides of the symmetrically distributed fixed tubes are slidably connected to sealing elements. The fixed frame is slidably connected to centrally symmetrically distributed racks. The sealing elements contact adjacent racks and are used to drive adjacent racks to move. Each rack is fixed to a connecting frame that is rotatably connected to an adjacent rotating drum. The fixed frame is rotatably connected to gears that mesh with the centrally symmetrically distributed racks.

[0013] More preferably, the airbag contains thermally expanding gas.

[0014] More preferably, the isolation assembly includes telescopic sleeves arranged in a linear array, the number of which is the same as the number of fixed frames. The telescopic sleeves are used to collect abnormal batteries. The telescopic sleeves arranged in a linear array are all fixed to the protective cabinet. The protective cabinet is fixed to a multi-stage spring telescopic rod arranged in a linear array. The telescopic ends of the multi-stage spring telescopic rods are fixed to connecting rods. The number of connecting rods is the same as the number of fixed frames. The connecting rods are fixed to adjacent telescopic sleeves.

[0015] More preferably, the removal assembly includes a second electric slide rail disposed inside the cabinet door of the protective cabinet. An electric push rod is fixedly connected to the electric slide rail of the second electric slide rail, and a U-shaped frame is fixedly connected to the telescopic end of the electric push rod. The U-shaped frame is used to push out the abnormal battery.

[0016] The beneficial effects of this invention are as follows: This invention proposes an innovative battery installation and thermal management structure. By designing each battery as an independently movable module and monitoring its temperature changes in real time during operation, when an abnormal temperature rise is detected in a battery, the adjacent X-shaped swing frame of the abnormal battery actively breaks away from contact with other X-shaped swing frames, thereby facilitating the removal of the abnormal battery. Subsequently, the abnormal battery is removed from the main battery pack, thereby achieving the effect of transferring the heat source and preventing heat accumulation and thermal runaway. Finally, the arrangement of the remaining X-shaped swing frames and batteries is adjusted to ensure that the spacing between each battery is balanced, thereby improving the overall heat dissipation efficiency.

[0017] By combining the detection of abnormally high battery temperature and heat dissipation with the detection of battery deformation and expansion, the battery can be monitored in real time, facilitating the removal of abnormal batteries. Attached Figure Description

Detailed Implementation

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] To address the issues that batteries in existing energy storage devices experience overheating during charging and discharging due to decreased chemical stability during long-term use, and the expansion of batteries before heating up not only affects their structural integrity but also exacerbates local temperature rise, creating a vicious cycle that ultimately leads to thermal runaway and threatens the safety and stable operation of the entire system, this invention proposes a novel battery installation and thermal management method. This method involves setting each battery as an independently movable module and monitoring its temperature changes in real time during system operation. When the temperature of a battery abnormally rises, it is automatically removed from the main battery array, thus transferring the heat source in a timely manner and avoiding the risk of heat accumulation and thermal runaway. Subsequently, the arrangement of the remaining batteries is dynamically adjusted to ensure uniform spacing between them, achieving a more uniform heat dissipation effect and thus providing overall safety and stability.

[0035] Example 1

[0036] An energy-saving and environmentally friendly energy storage device, such as Figures 1-8As shown, the device includes a protective cabinet 1, inside which are two pairs of fixed frames 2. The two fixed frames 2 in each pair are symmetrically distributed vertically. The symmetrically distributed fixed frames 2 are slidably connected by symmetrically distributed first sliding frames 3. The fixed frames 2 are equipped with springs located between the symmetrically distributed first sliding frames 3. A linear array of rotating cylinders 4 is arranged between the symmetrically distributed first sliding frames 3. The rotating cylinders 4 are equipped with X-shaped swing frames 5. The rotating cylinders 4 are slidably connected to connectors 6. A fixed frame 7 is fixed between two connectors 6 at the same height. A battery 8 is placed inside the fixed frame 7. A docking assembly is provided on the first sliding frame 3 to connect the X-shaped swing frames 5 on the same side. A monitoring assembly is provided on the fixed frame 7 to monitor adjacent batteries 8. An isolation assembly with a linear array and the same number of batteries 8 is provided outside the protective cabinet 1 to isolate abnormal batteries 8. The cabinet door of the protective cabinet 1 is equipped with a removal assembly for pushing out abnormal batteries 8.

[0037] In the above scheme, the X-shaped swing frame 5 consists of two cross-distributed hinged rods. The rotating cylinder 4 is fixed to one of the hinged rods and rotatably connected to the other hinged rod. The rotating cylinder 4 is arranged in a straight array in the vertical direction. When the temperature of a certain battery 8 rises abnormally, the two X-shaped swing frames 5 adjacent to the battery 8 actively break away from contact with other X-shaped swing frames 5, thereby facilitating the removal of the abnormal battery 8. Subsequently, the abnormal battery 8 is removed from the main battery pack to achieve the effect of transferring the heat source and preventing heat accumulation and thermal runaway. Finally, the arrangement of the remaining X-shaped swing frames 5 and batteries 8 is adjusted to maintain a balanced spacing between each battery 8, thereby ensuring the overall heat dissipation efficiency. The battery 8 can be a lithium iron phosphate battery. Because the positive electrode material of lithium iron phosphate batteries does not contain scarce metals such as cobalt and nickel, it reduces production energy consumption and resource consumption. Moreover, it does not cause soil and water pollution during manufacturing and use. Based on the above characteristics, lithium iron phosphate batteries are superior to battery types containing heavy metals in terms of material environmental protection and resource saving. Therefore, it was selected as the battery 8 used in this energy storage device.

[0038] like Figures 4-8 As shown, symmetrically distributed fixing plates 601 are fixed inside the protective cabinet 1, and the connectors 6 are attached to the corresponding fixing plates 601. The fixing plates 601 are used to guide the connectors 6 on the same side.

[0039] In the above scheme, the fixing plate 601 keeps the fixing frame 7 and the battery 8 stable.

[0040] like Figures 8-11As shown, the docking assembly includes equidistantly distributed first hook tail frames 10 and equidistantly distributed second hook tail frames 11. The upper first hook tail frame 10 is fixed to the corresponding first sliding frame 3, and the lower second hook tail frame 11 is slidably connected to the corresponding first sliding frame 3. The remaining second hook tail frames 11 and first hook tail frames 10 are respectively hinged to the upper and lower sides of the corresponding X-shaped swing frame 5. Both the second hook tail frames 11 and the first hook tail frames 10 are rotatably connected to hook tongues 12. Torsion springs are provided between the first hook tail frames 10 and the second hook tail frames 11 and their corresponding hook tongues 12. Both the second hook tail frames 11 and the first hook tail frames 10 are slidably connected to locking pins 13. The locking pins 13 are used to limit the movement of adjacent hook tongues 12. The first hook tail frames 10 and the second hook tail frames 11 are respectively connected to the corresponding hook tongues 12. A tension spring is provided between the locking pins 13, and two adjacent hook tongues 12 limit each other. An elastic plate 14 is fixed to the locking pin 13, and two adjacent elastic plates 14 limit each other. Except for the second hook tail frame 11 sliding on the lower side of the first sliding frame 3 and the first hook tail frame 10 fixed on the upper side of the first sliding frame 3, the remaining first hook tail frame 10 and second hook tail frame 11 are provided with elastic rings 15 on the side near the adjacent first sliding frame 3. All elastic rings 15 are used to restrict the corresponding first hook tail frame 10 and the corresponding second hook tail frame 11 to the first sliding frame 3. The symmetrically distributed fixed frames 2 are jointly fixed to the first electric slide rail 16. The electric slider of the first electric slide rail 16 is fixed to the second sliding frame 17. The second sliding frame 17 is fixed to the second hook tail frame 11 located on the lower side.

[0041] In the above scheme, after the second hook tail frame 11 and the first hook tail frame 10 are connected, it can be referred to Figure 11 The two hooks 12 limit each other. At this time, the torsion springs adjacent to the hooks 12 are in a torsional storage state. In this case, the tension springs adjacent to the locking pin 13 are in an unstretched state. One of the two adjacent elastic plates 14 is convex and the other is concave, so that when either of the two elastic plates 14 moves, it can drive the other elastic plate 14 to move synchronously.

[0042] like Figure 6 , Figure 7 , Figure 12 and Figure 13 As shown, the monitoring component includes symmetrically distributed airbags 19, all of which are fixed to the fixed frame 7. The opposing sides of the symmetrically distributed airbags 19 are in contact with adjacent batteries 8. The fixed frame 7 is fixed and connected to symmetrically distributed fixed tubes 20. The opposing sides of the symmetrically distributed fixed tubes 20 are slidably connected to sealing elements 21. The fixed frame 7 is slidably connected to centrally symmetrically distributed racks 22. The sealing elements 21 are in contact with adjacent racks 22 and are used to drive the adjacent racks 22 to move. The racks 22 are fixedly connected to a connecting frame 23 that is rotatably connected to the adjacent rotating drum 4. The fixed frame 7 is rotatably connected to a gear 24 that meshes with the centrally symmetrically distributed racks 22.

[0043] In the above scheme, the fixing tube 20 is J-shaped, and the sealing element 21 is located on the upper side inside the fixing tube 20. When the pressure inside the airbag 19 and the fixing tube 20 increases, it squeezes the sealing element 21, causing the sealing element 21 to push the adjacent rack frame 22. The adjacent rack frame 22, through meshing with the gear 24, drives the rack frame 22 on the other side to move synchronously. In this way, the movement of the two rack frames 22 can be triggered when either side of the battery 8 deforms.

[0044] like Figure 6 , Figure 7 , Figure 12 and Figure 13 As shown, the isolation assembly includes telescopic sleeves 25 arranged in a linear array. The number of telescopic sleeves 25 is the same as that of the fixed frames 7. The telescopic sleeves 25 are used to collect abnormal batteries 8. The telescopic sleeves 25 arranged in a linear array are all fixed to the protective cabinet 1. The protective cabinet 1 is fixed to a multi-stage spring telescopic rod 26 arranged in a linear array. The telescopic ends of the multi-stage spring telescopic rods 26 are fixed to connecting rods 27. The number of connecting rods 27 is the same as that of the fixed frames 7. The connecting rods 27 are fixed to the adjacent telescopic sleeves 25.

[0045] In the above scheme, when the telescopic sleeve 25 is fully extended, the abnormal battery 8 is temporarily stored. When the abnormal battery 8 enters the telescopic sleeve 25, the telescopic part of the multi-stage spring telescopic rod 26 has already extended, but the elasticity of the multi-stage spring telescopic rod 26 itself is insufficient to drive the telescopic sleeve 25 to retract through the connecting rod 27.

[0046] like Figure 3 and Figure 14 As shown, the removal component includes a second electric slide rail 28, which is located inside the cabinet door of the protective cabinet 1. An electric push rod 29 is fixedly connected to the electric slide rail 28, and a U-shaped frame 30 is fixedly connected to the telescopic end of the electric push rod 29. The U-shaped frame 30 is used to push out the abnormal battery 8.

[0047] In the above scheme, the side of the U-shaped frame 30 away from the telescopic end of the electric push rod 29 is provided with two inclined surfaces to facilitate the U-shaped frame 30 in supporting the battery 8 and the fixing frame 7.

[0048] Working principle: When the temperature of a battery 8 rises abnormally and expands, taking the uppermost battery 8 as an example, the thermal management control unit inside the battery 8 has already detected that the battery 8 has undergone structural deformation. At this time, conventional cooling methods can no longer effectively suppress the temperature rise, indicating that the battery 8 is in the early stage of thermal runaway and needs to be isolated immediately to prevent the risk from spreading. The thermal management control unit inside the battery 8 transmits an electrical signal to the control terminal. The control terminal manipulates the electric slider in the second electric slide rail 28 to drive the electric push rod 29 to move towards the uppermost battery 8, so that the center line of the electric push rod 29 moves to coincide with the center line of the uppermost battery 8. Then the electric push rod 29 stops moving. At this time, the control terminal manipulates the telescopic end of the electric push rod 29 to extend, so that the U-shaped frame 30 of the telescopic end of the electric push rod 29 clamps the fixing frame 7 and the battery 8, thereby facilitating the subsequent transfer of the battery 8.

[0049] After clamping the abnormal battery 8, the battery 8 expands and compresses the adjacent airbag 19, increasing the pressure inside the airbag 19 and the adjacent fixing tube 20. This causes the seal 21 to move along the adjacent fixing tube 20 and compress the adjacent rack frame 22. As the rack frame 22 moves, it drives the gear 24 to rotate, thus causing the rack frame 22 on the other side to move synchronously. As the two rack frames 22 move towards each other, they respectively drive the rotating drum 4 to move towards the side closer to the adjacent battery 8 through the adjacent connecting frame 23. The following only takes the movement process of one side of the parts as an example. The movement process of the other side of the parts is the same. During the movement of the rotating drum 4, it drives the upper part of the rotating drum 4 through the adjacent X-shaped swing frame 5. The two second hook tail frames 11 and the two first hook tail frames 10 located on the lower side move synchronously. The movement process of the upper part on the X-shaped swing frame 5 is described first: During the movement of the upper second hook tail frame 11, the elastic plate 14 contacts the elastic plate 14 on the upper first hook tail frame 10, thereby causing the elastic plate 14 on the upper first hook tail frame 10 to pull the adjacent locking pin 13 to move. During the movement of the locking pin 13, the adjacent tension spring is stretched and gradually disengages from the limit of the adjacent hook tongue 12. At this time, the hook tongue 12 rotates under the action of the adjacent torsion spring and locks the adjacent locking pin 13, so that the locking pin 13 cannot be reset under the action of the tension spring, thus preparing for the subsequent re-connection.

[0050] As the rotating drum 4 and the adjacent X-shaped swing frame 5 move closer to the abnormal battery 8, when the locking pin 13 releases the restriction on the adjacent hook tongue 12, the elastic plate 14 on the second hook tail frame 11 on the upper side of the X-shaped swing frame 5 no longer contacts the adjacent elastic plate 14.

[0051] The following describes the movement process of the lower part on the X-shaped swing frame 5: During the movement of the rotating drum 4 near the abnormal battery 8 and the adjacent X-shaped swing frame 5, the first hook tail frame 10 located on the lower side of the X-shaped swing frame 5 moves synchronously through the elastic plate 14, driving the adjacent elastic plate 14 to move synchronously (before this, because the elastic ring 15 limits the adjacent second hook tail frame 11, the two adjacent elastic plates 14 will move synchronously). The process of the elastic plate 14 moving and releasing the limit on the adjacent hook tongue 12 is the same as above. During the movement of the X-shaped swing frame 5, the two second hook tail frames 11 and the two first hook tail frames 10 near the X-shaped swing frame 5 move their elastic rings 15 laterally towards the side closer to the battery 8. During the movement of the elastic ring 15, it is squeezed by the inner side of the adjacent first sliding frame 3, thus deforming.

[0052] When the X-shaped swing frame 5 near the abnormal battery 8 moves the two second hook tail frames 11 and the two first hook tail frames 10 to no longer contact the corresponding first hook tail frame 10 and the corresponding second hook tail frame 11 (the elastic ring 15 is now located on the side of the first sliding frame 3 near the battery 8 and resets under its own elasticity), the abnormal battery 8 and the corresponding X-shaped swing frame 5 and its parts are no longer in the queue. At that time, the abnormal battery 8 can move to the rear as the extension end of the electric push rod 29 extends. The fixed frame 7, the battery 8, the corresponding X-shaped swing frame 5, the rotating cylinder 4 and its parts then move into the adjacent telescopic sleeve 25 (during the movement, the fixed frame 7 causes the adjacent connecting piece 6 to disengage from the fixed plate 601). Therefore, the abnormally heated battery 8 is moved out of the main area in time to prevent heat diffusion and reduce the risk of thermal runaway.

[0053] When the abnormal battery 8 has moved the fixed frame 7 to the rear side of the two and fits against the inner side of the adjacent telescopic sleeve 25, the abnormal battery 8 squeezes the inner side of the telescopic sleeve 25, thereby stretching the rear part of the telescopic sleeve 25. During the stretching process, the telescopic part of the multi-stage spring telescopic rod 26 is pulled out through the connecting rod 27.

[0054] When the malfunctioning battery 8 has moved the fixed frame 7 and related parts into the telescopic sleeve 25 (because the elasticity of the multi-stage spring telescopic rod 26 is insufficient to reset the battery 8 and related parts, the battery 8 and related parts remain stationary after entering the telescopic sleeve 25), the telescopic end of the electric push rod 29 drives the U-shaped frame 30 to retract. During this process, the U-shaped frame 30 gradually disengages from the malfunctioning battery 8 and the fixed frame 7.

[0055] When the telescopic end of the electric push rod 29 is fully retracted, the control terminal manipulates the electric slider in the first electric slide rail 16 to drive the second sliding frame 17 to move upward. The second sliding frame 17 drives the two adjacent second hook tail frames 11 to move upward along the adjacent first sliding frame 3 respectively. Through the movement of the two second hook tail frames 11 on the second sliding frame 17, the second hook tail frames 11 and the first hook tail frames 10 on the same side are driven by the X-shaped swing frame 5 and the rotating cylinder 4 to lift the connecting piece 6, the fixing frame 7, the battery 8 and the wire-related parts synchronously upward (the second hook tail frames 11 and the first hook tail frames 10 move along the adjacent first sliding frame 3 respectively during the movement). When the above parts are lifted to the point where the adjacent second hook tail frames 11 and the first hook tail frames 10 are connected, the second hook tail frames 11 move closer to the first hook tail frames 10, so that the hook tongues 12 inside them come into contact and rotate along the second hook tail frames 11 and the first hook tail frames 10 respectively under the action of mutual compression (during the rotation of both, the adjacent torsion springs are gradually tightened).

[0056] After the two hook tongues 12 are docked, the two locking pins 13 lock the corresponding hook tongues 12 under the action of the adjacent tension springs. Through the movement of the above parts, the remaining battery 8 and related parts are re- docked. Then, the control terminal manipulates the electric slider in the first electric slide rail 16 to drive the second sliding frame 17 to move downward and reset. The second sliding frame 17 drives the two adjacent second hook tail frames 11 to move downward along the adjacent first sliding frame 3. Through the movement of the two second hook tail frames 11 on the second sliding frame 17, the remaining X-shaped swing frame 5 and its second hook tail frames 11 and first hook tail frames 10, battery 8 and related parts all move downward. During the movement, the X-shaped swing frame 5 swings crosswise, which causes the two symmetrically distributed first sliding frames 3 to move towards each other, so that the remaining X-shaped swing frames 5 all swing crosswise.

[0057] When the second sliding frame 17 moves to the position Figure 9 After the component stops moving at its current position, the remaining batteries 8 are rearranged during the movement to ensure that the distance between each battery 8 remains consistent. This action adjusts the spacing of the remaining batteries 8, which helps to enhance airflow or the coverage of the cooling medium and improve overall heat dissipation efficiency.

[0058] Example 2

[0059] Based on Embodiment 1, a reflective coating (e.g., an aluminum-based or silver-based coating) may be provided on the outer side of the telescopic housing 25. This is to reduce the influence of the external environment on the temperature inside the telescopic housing 25 by reducing the conduction and radiation of external heat sources after the abnormal battery 8 and the fixing frame 7 enter the telescopic housing 25.

[0060] Example 3

[0061] Based on Embodiment 2, multiple interlocking curtains (which can be flexible heat-insulating curtains) can be provided on the front side of the telescopic housing 25 to allow the abnormal battery 8 and the fixing frame 7 to enter the telescopic housing 25 and block the front side of the telescopic housing 25, thereby achieving the effect of isolating the abnormal battery 8 separately.

[0062] Example 4

[0063] Based on Example 3, the airbag 19 contains thermal expansion gas. When the thermal expansion gas in the airbag 19 senses an abnormal increase in temperature of the adjacent battery 8, the pressure in the airbag 19 also increases, thereby triggering the movement of the seal 21. This achieves the effect of removing the abnormal battery 8 by moving the aforementioned parts when the battery 8 has an abnormally high temperature but has not deformed.

[0064] Although the invention has been described with reference to exemplary embodiments, it should be understood that the invention is not limited to the disclosed exemplary embodiments.
