Description

Technical Field

[0001] This invention relates to the field of energy storage technology, and in particular to an energy storage type charging and swapping cabinet. Background Technology

[0002] With the rapid development of the new energy industry, the demand for energy storage charging and swapping cabinets is also increasing. As the core supporting and safeguarding equipment in the battery charging process, the safety performance of energy storage charging and swapping cabinets is directly related to the stability and safety of the charging process. In particular, the potential problem of battery thermal runaway during battery charging has become a key technical bottleneck restricting the development of energy storage charging and swapping cabinets.

[0003] In the current field of energy storage charging and swapping cabinet technology, existing technologies generally employ spray cooling to address potential thermal runaway during battery charging. The core principle of this technology is to install a spray device inside the energy storage charging and swapping cabinet. When signs of thermal runaway are detected in the battery (such as a sudden temperature rise or the generation of smoke), the spray device is activated, spraying cooling water onto the thermally runaway battery to achieve the purpose of cooling.

[0004] However, long-term practical application has revealed that existing spray-based thermal runaway response technologies suffer from low and uneven cooling efficiency. During the spraying process, cooling water mainly covers the battery surface from top to bottom. Due to limitations in spray angle, water pressure, and the battery's own structure (such as the battery casing obstructing the view), the cooling water cannot evenly cover all heat-generating areas of the battery, especially the bottom, sides, and gaps inside the battery pack, which easily create cooling dead zones. The existence of these cooling dead zones prevents the local temperature of the battery from being reduced in time, which not only affects the overall cooling effect but may also become potential sources of further thermal runaway. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a battery cell to solve the problem in the prior art where the battery has poor cooling uniformity during thermal runaway during charging, resulting in poor cooling effect.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] An energy storage charging and swapping cabinet includes an energy storage charging unit and a cabinet. The energy storage charging unit is disposed inside the cabinet and is used to charge batteries. The energy storage charging unit includes a housing and a partition. The partition is disposed inside the housing and divides the housing into a battery compartment and a water storage compartment. The battery compartment is used to hold batteries, and the water storage compartment contains cooling water. The partition can support the batteries when they are charging normally, and can also open in the event of battery thermal runaway, allowing the batteries to automatically slide into the water storage compartment under gravity and be submerged in cooling water.

[0008] Furthermore, the partition includes a first blade and a second blade, both of which are rotatably mounted inside the housing.

[0009] Furthermore, the partition also includes a thermal switch, which is used to control the opening of the first and second leaf plates according to the temperature changes inside the box.

[0010] Furthermore, the first leaf plate is provided with a locking tongue groove; the second leaf plate is provided with a mounting groove.

[0011] Furthermore, the locking tongue groove is arranged opposite to the mounting groove.

[0012] Furthermore, the thermal switch includes a locking tongue, a return spring, and a clamping member.

[0013] Furthermore, the latch is installed in the mounting groove and can be inserted into or removed from the latch groove.

[0014] Furthermore, the return spring is installed in the mounting groove to apply elastic tension to the latch.

[0015] Furthermore, one end of the clamping member abuts against the latch, and the other end abuts against the inner wall of the mounting groove, and the clamping member is used to support the latch.

[0016] Furthermore, it also includes an alarm unit, which comprises a smoke detector, an alarm indicator light, and a PLC controller.

[0017] Furthermore, the clamping component includes a clamping glass body containing a thermosensitive expansion agent. When the battery experiences thermal runaway and triggers a fire, the thermosensitive expansion agent expands due to heat, causing the clamping glass body to rupture.

[0018] Furthermore, the energy storage charging unit also includes a safety socket installed inside the battery compartment. The safety socket not only enables the battery to be connected to the power system, but also works in conjunction with the separator to disconnect the battery from the power system when no power is needed in the event of battery thermal runaway.

[0019] Furthermore, the safety socket includes a base, an adapter, a disconnect spring, and a trigger. The base is fixedly installed inside the battery compartment and connected to the power system. The adapter is installed inside the base and can be plugged into the battery. The disconnect spring is installed inside the base and abuts against the adapter, and the disconnect spring is used to apply an elastic thrust to the adapter. The trigger passes through the base and is inserted into the adapter, used to lock or unlock the adapter.

[0020] Furthermore, the trigger is connected to the second blade, and the rotation of the second blade controls the action of the trigger to release the lock on the adapter.

[0021] Furthermore, the trigger includes a trigger pin and a control rope. The trigger pin is mounted on the base and used for locking the adapter. One end of the control rope is connected to the trigger pin, and the other end is connected to the rotating shaft of the second leaf plate.

[0022] The technical solution of this invention can achieve at least one of the following effects:

[0023] (1) The energy storage charging and swapping cabinet of the present invention includes an energy storage charging unit and a cabinet. The energy storage charging unit is disposed in the cabinet and is used to charge the battery. The energy storage charging unit includes a box and a partition. The partition is disposed in the box and divides the box into a battery holding compartment and a water storage compartment. The battery holding compartment is used to place the battery, and the water storage compartment is filled with cooling water. The partition can support the battery when the battery is charging normally. When the battery is thermally runaway, it can also open so that the battery can automatically slide into the water storage compartment under the action of gravity and be immersed in the cooling water. By directly immersing the battery in the cooling water, the present invention can achieve a faster and more uniform cooling effect, effectively prevent the further spread of thermal runaway, and thus significantly improve the efficiency of battery thermal runaway management.

[0024] (2) The partition of the present invention includes a first leaf plate, a second leaf plate and a thermal switch. The first leaf plate and the second leaf plate are rotatably installed in the housing and locked and fixed by the thermal switch. When the battery is charging normally, the thermal switch locks and fixes the first leaf plate and the second leaf plate to support the battery. Once the battery experiences thermal runaway, the thermal switch automatically unlocks the first leaf plate and the second leaf plate after being heated. The first leaf plate and the second leaf plate flip under the action of gravity, opening the bottom of the battery compartment. The battery then slides quickly into the water storage tank under its own gravity and is immersed in the cooling water to ensure that the battery can quickly leave the high temperature environment and enter the cooling water for efficient cooling when thermal runaway occurs, effectively avoiding greater losses caused by heat spread.

[0025] (3) The energy storage charging unit of the present invention further includes a safety socket, which includes a base, an adapter, a disconnect spring, and a trigger. The base is fixedly installed in the battery compartment and connected to the power system. The adapter is installed in the base and can also be plugged into the battery and connected to the power system through the base. One end of the disconnect spring is fixedly installed in the base, and the other end abuts against the adapter. The disconnect spring is used to always apply an elastic thrust to the adapter, so that the adapter maintains the potential energy to be withdrawn from the base. The trigger passes through the base and is inserted into the adapter, and is used to activate the adapter. The adapter is locked to ensure that the battery is in a normal charging state, inserted into the base, and connected to the power system. The trigger is also connected to the second leaf plate. The rotation of the second leaf plate controls the action of the trigger to release the lock on the adapter. Under the elastic thrust of the disconnect spring, the adapter is quickly ejected from the base, realizing the rapid and synchronous disconnection of the battery from the power system when no power is needed. This allows the battery to quickly slide into the water tank and be submerged in cooling water for cooling, while simultaneously disconnecting the battery and power system cables when no power is needed, providing dual safety protection.

[0026] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0041] Example 1

[0042] A specific embodiment of the present invention discloses an energy storage type charging and swapping cabinet, such as... Figure 1 and Figure 2 As shown, it includes an energy storage and charging unit 1 and a cabinet 2. The energy storage and charging unit 1 is installed inside the cabinet 2 and is used to charge the battery.

[0043] Preferably, the energy storage and charging unit 1 includes a housing 11 and a partition 12. The partition 12 is disposed inside the housing 11, dividing the housing 11 into a battery compartment 111 and a water storage compartment 112. The battery compartment 111 is used to hold the battery. The water storage compartment 112 is located below the battery compartment 111 and contains cooling water. The partition 12 can support the battery during normal charging and can also quickly open in the event of battery thermal runaway, allowing the battery to quickly and automatically slide into the storage compartment under gravity. The battery is placed in a water tank 112 and submerged in cooling water. The cooling water rapidly absorbs the heat generated by the battery, preventing heat spread. At the same time, the submersion of the battery in cooling water can effectively suppress battery combustion, achieving rapid cooling of the battery in thermal runaway. Compared with the existing technology of spraying cooling to manage battery thermal runaway, this invention achieves a faster and more uniform cooling effect by directly immersing the battery in cooling water, effectively preventing further spread of thermal runaway, thereby significantly improving the efficiency of battery thermal runaway management.

[0044] Preferably, such as Figure 3 As shown, the partition 12 includes a first leaf plate 121, a second leaf plate 122, and a thermal switch 123. The first leaf plate 121 and the second leaf plate 122 are rotatably installed inside the housing 11, and the first leaf plate 121 and the second leaf plate 122 are locked and fixed by the thermal switch 123. When the battery is charging normally, the thermal switch 123 locks and fixes the first leaf plate 121 and the second leaf plate 122 to support the battery. Once the battery experiences thermal runaway, the thermal switch 123 automatically unlocks the first leaf plate 121 and the second leaf plate 122 after being heated. The first leaf plate 121 and the second leaf plate 122 flip under the action of gravity, opening the bottom of the battery compartment 111. The battery then quickly slides into the water storage compartment 112 and is immersed in cooling water to ensure that the battery can quickly leave the high-temperature environment and enter the cooling water for efficient cooling in the event of thermal runaway, effectively avoiding greater losses caused by heat spread.

[0045] Preferably, the response temperature of the thermal switch 123 is set between 80°C and 120°C to ensure that it can be triggered in the early stage of battery thermal runaway, thereby achieving rapid response and effective protection.

[0046] Preferably, the first leaf plate 121 is provided with a locking tongue groove 1211; the second leaf plate 122 is provided with a mounting groove 1221; the locking tongue groove 1211 and the mounting groove 1221 are arranged opposite to each other, and the mounting groove 1221 is used to install a thermal switch 123. The thermal switch 123 cooperates with the locking tongue groove 1211 to lock or release the first leaf plate 121 and the second leaf plate 122.

[0047] Preferably, such as Figure 4As shown, the thermal switch 123 includes a latch 1231, a return spring 1232, and a clamping member 1233. One end of the latch 1231 is slidably installed in the mounting groove 1221, and the other end can be inserted into or removed from the latch groove 1211. One end of the return spring 1232 is fixedly connected to the latch 1231, and the other end is fixedly connected to the inner wall of the mounting groove 1221. The return spring 1232 is used to apply an elastic tension to the latch 1231 at all times, so that the latch 1231 maintains the potential energy of being removed from the latch groove 1211. One end of the clamping member 1233 abuts against the latch 1231, and the other end abuts against the inner wall of the mounting groove 1221. When the battery is under normal charging, that is, when the temperature in the battery compartment 111 is lower than the response temperature of the low-pressure thermal switch 123, the clamping member 1233 overcomes the return spring. The tension of the spring 1232 on the locking tongue 1231 causes the locking tongue 1231 to insert and press against the locking tongue groove 1211, thereby locking and fixing the first leaf plate 121 and the second leaf plate 122 to support the battery. When the battery experiences thermal runaway and causes a fire, that is, when the temperature inside the battery compartment 111 is higher than the response temperature of the thermal switch 123, the pressing member 1233 expands and breaks due to heat, causing the locking tongue 1231 to lose support. Under the elastic tension of the return spring 1232, the locking tongue 1231 quickly exits from the locking tongue groove 1211, quickly releasing the lock between the first leaf plate 121 and the second leaf plate 122. Then, the first leaf plate 121 and the second leaf plate 122 flip under the action of gravity, opening the bottom of the battery compartment 111, and the battery quickly slides into the water storage tank 112 and is submerged in cooling water.

[0048] Preferably, such as Figure 5 As shown, the clamping member 1233 includes a clamping glass body 12331, which contains a thermosensitive expansion agent. When the battery experiences thermal runaway, the thermosensitive expansion agent expands due to heat, causing the clamping glass body 12331 to rupture. At this time, the locking tongue 1231 loses its support, and under the elastic tension of the return spring 1232, the locking tongue 1231 quickly exits from the locking tongue groove 1211, thereby quickly releasing the lock between the first leaf plate 121 and the second leaf plate 122. Subsequently, the first leaf plate 121 and the second leaf plate 122 flip under the action of gravity, causing the bottom of the battery compartment 111 to open, and the battery quickly slides into the water storage compartment 112 and is immersed in the cooling water.

[0049] Preferably, the thermosensitive expanding agent is kerosene.

[0050] Preferably, the clamping member 1233 includes an axial damper, which includes a first damping spring 12332 and a second damping spring 12333. The first damping spring 12332 and the second damping spring 12333 are respectively fixedly installed at both ends of the clamping glass body 12331. The first damping spring 12332 is also fixedly connected to the locking tongue 1231, and the second damping spring 12333 is also fixedly connected to the inner wall of the mounting groove 1221. By setting the first damping spring 12332 and the second damping spring 12333, the vibration and impact of the clamping glass body 12331 under normal conditions can be effectively buffered, especially the vibration and impact along the axial direction of the clamping glass body 12331. This effectively prevents the clamping glass body 12331 from being accidentally triggered and broken due to external vibration, thereby significantly improving the reliability and safety of the energy storage charging unit 1.

[0051] Preferably, the clamping member 1233 further includes a radial damper (not shown in the figure), which includes multiple damping springs. The damping springs are evenly arranged along the circumference of the clamping glass body 12331, thereby effectively buffering the vibration and impact along the radial direction of the clamping glass body 12331, further preventing accidental breakage caused by external vibration, and thus significantly improving the reliability and safety of the energy storage charging unit 1.

[0052] Preferably, the energy storage charging and swapping cabinet further includes an alarm unit 3, which includes a smoke detector (not shown in the figure), an alarm indicator light, and a PLC controller (not shown in the figure). The smoke detector is installed in each energy storage charging unit 1 to monitor the smoke and gas conditions of each energy storage charging unit 1 and to issue an alarm when an abnormality is detected. The smoke detector is connected to the PLC controller and can transmit the detected danger signal to the PLC controller in real time. The alarm indicator light is fixedly installed on the cabinet 2 and connected to the PLC controller. Through the control of the PLC controller, the alarm indicator light can be made to light up according to the danger signal transmitted by the smoke detector, thereby warning the surrounding people to stay away and notifying remote management personnel to take immediate countermeasures.

[0053] Example 2

[0054] Example 2 is a further improvement based on Example 1, such as... Figure 2As shown, the energy storage charging unit 1 also includes a safety socket 13, which is installed inside the battery compartment 111. The safety socket 13 not only enables the battery to be quickly connected to the power system, but also enables the battery to be quickly disconnected from the power system in the event of thermal runaway, reducing the potential harm of the thermal runaway battery to the power system. In addition, in the event of battery thermal runaway, the safety socket 13 can also be linked with the partition 12. While the battery is quickly slid into the water storage tank 112 and submerged in cooling water, the safety socket 13 can quickly disconnect the battery from the power system without the need for power, effectively reducing the adverse effects of the thermal runaway battery on the power system, thereby achieving dual safety protection.

[0055] Preferably, such as Figure 6 As shown, the safety socket 13 includes a base 131, an adapter 132, a disconnect spring 133, and a trigger 134. The base 131 is fixedly installed inside the battery compartment 111 and connected to the power system. The adapter 132 is installed inside the base 131 and can also be plugged into the battery and connected to the power system through the base 131. One end of the disconnect spring 133 is fixedly installed inside the base 131, and the other end abuts against the adapter 132. The disconnect spring 133 is used to continuously apply an elastic pushing force to the adapter 132, so that the adapter 132 maintains the potential energy to be withdrawn from the base 131. The trigger 134 passes through the base 131 and is inserted into the adapter 132, using... The adapter 132 is locked to ensure that the battery is in a normal charging state, the adapter 132 is inserted into the base 131, and maintains the connection with the power system. The trigger 134 is also connected to the second leaf plate 122. The rotation of the second leaf plate 122 controls the action of the trigger 134 to release the lock on the adapter 132. Under the elastic thrust of the disconnection spring 133, the adapter 132 quickly pops out from the base 131, realizing the rapid and synchronous disconnection of the battery and the power system when no power is needed. This allows the battery to quickly slide into the water tank 112 and be immersed in the cooling water for cooling, while simultaneously disconnecting the battery and power system cables when no power is needed, providing dual safety protection.

[0056] Preferably, such as Figure 7 As shown, the base 131 is provided with a first mounting cavity 1311, a second mounting cavity 1312 and a through hole 1313. The first mounting cavity 1311 is used to install the adapter 132 and the disconnecting spring 133, and the through hole 1313 is used to install the trigger 134.

[0057] Preferably, such as Figure 8 As shown, the adapter 132 is provided with a locking hole 1321.

[0058] Preferably, the safety socket 13 further includes a ring lock 135, which is installed in the second mounting cavity 1312. The ring lock 135 is used to axially and circumferentially lock the adapter 132 installed in the first mounting cavity 1311 to prevent the adapter 132 from being accidentally displaced or rotated during operation, thereby further improving the safety and stability of the connection. In addition, the ring lock 135 can also make the elastic thrust of the disconnection spring 133 on the adapter 132 more evenly distributed, thereby improving the motion stability and response speed of the adapter 132 during the disconnection process, ensuring that it can reliably and quickly detach from the base 131 in an emergency, further enhancing the safety guarantee for disconnection between the battery and the power system.

[0059] Preferably, such as Figure 9 As shown, the ring lock 135 includes a locking pin 1351, which is installed in the second mounting cavity 1312 and can be inserted into or removed from the lock hole 1321. When the locking pin 1351 is inserted into the lock hole 1321, it can lock the adapter 132 in the first mounting cavity 1311, thereby achieving axial and circumferential locking of the adapter 132. When the locking pin 1351 is removed from the lock hole 1321, it can release the locking of the adapter 132. Then, under the elastic thrust of the disconnecting spring 133, the adapter 132 is quickly ejected from the base 131, thereby achieving rapid disconnection of the battery from the power system without the need for power intervention.

[0060] Preferably, multiple locking holes 1321 are provided, and the multiple locking holes 1321 are evenly arranged on the outer circumference of the adapter 132; multiple locking pins 1351 are provided, and their number is equal to the number of locking holes 1321. Through the precise cooperation of multiple locking pins 1351 with multiple evenly arranged locking holes 1321, the elastic thrust of the disconnection spring 133 on the adapter 132 can be more evenly distributed, thereby significantly improving the motion stability and response speed of the adapter 132 during the disconnection process. This ensures that in an emergency, the adapter 132 can reliably and quickly detach from the base 131, further strengthening the safety guarantee for disconnection between the battery and the power system.

[0061] Preferably, the ring lock 135 further includes a control disk 1352 and a power spiral spring 1353. The control disk 1352 is installed in the second mounting cavity 1312 and can rotate within the second mounting cavity 1312. One end face of the control disk 1352 is connected to a plurality of locking pins 1351, and the other end face is fixedly connected to one end of the power spiral spring 1353. The other end of the power spiral spring 1353 is fixedly connected to the inner wall of the second mounting cavity 1312. The control disk 1352 is used to control the synchronous movement of the plurality of locking pins 1351, thereby realizing the synchronous retraction of the plurality of locking pins 1351. The locking hole 1321 is used to release the lock of the adapter 132; when the power spring 1353 is in the energy storage state, it is used to provide power for the rotation of the control disk 1352; the control disk 1352 is also connected to the trigger 134. The trigger 134 releases the lock on the control disk 1352, the power spring 1353 releases the stored energy, drives the control disk 1352 to rotate, thereby driving multiple locking pins 1351 to exit the locking hole 1321 simultaneously, realizing the rapid unlocking and ejection of the adapter 132, thereby ensuring that the battery can be quickly and safely disconnected from the power system in an emergency.

[0062] Preferably, such as Figure 10 As shown, the control panel 1352 is provided with a fixing hole 13521.

[0063] Preferably, the trigger 134 includes a trigger pin and a control rope (not shown in the figure). The trigger pin is installed in the through hole 1313, with one end inserted into the fixing hole 13521 to lock the control disk 1352, and the other end connected to one end of the control rope. The other end of the control rope is connected to the shaft of the second leaf plate 122 and can be wound around the shaft of the second leaf plate 122. When the battery experiences thermal runaway, the thermal switch 123 is heated and automatically releases the locking of the first leaf plate 121 and the second leaf plate 122. The second leaf plate 122 flips under the action of gravity, causing the control rope to be wound around the shaft, thereby pulling the trigger pin out of the fixing hole 13521 and releasing the lock on the control disk 1352. The power spring 1353 releases its stored energy to drive the control disk 1352 to rotate, thereby driving multiple locking pins 1351 to simultaneously exit the locking hole 1321, realizing the rapid unlocking and ejection of the adapter 132, ensuring that the battery can be quickly and safely disconnected from the power system in an emergency.

[0064] Preferably, the control panel 1352 is further provided with a drive slide groove 13522, and the locking pin 1351 is provided with a drive protrusion. The drive protrusion is installed in the drive slide groove 13522 and can slide in the drive slide groove 13522. The drive slide groove 13522 is an arc-shaped slide groove, with one end close to the axis of the control panel 1352 and the other end extending away from the axis of the control panel 1352. When the control panel 1352 rotates, the drive slide groove 13522 drives the drive protrusion of the locking pin 1351 to slide along the arc-shaped slide groove, thereby causing the locking pin 1351 to move radially along the adapter seat 132 under the action of the drive slide groove 13522. This ensures that multiple locking pins 1351 can exit the lock hole 1321 synchronously, thereby unlocking the adapter seat 132 and significantly improving the reliability and synchronization of the action of multiple locking pins 1351.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
