[0034] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present disclosure.

[0035] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0036] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0037] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0038] See also Figure 1 and Figure 2 The battery compartment for the energy storage system disclosed in the present invention includes a storage compartment 10, a shelf 20, a sliding member 30 for loading a battery pack 900, and a locking assembly 40.

[0039] The storage bin 10 is formed with a storage cavity 1101. The shelf 20 is disposed in the storage cavity 1101. A plurality of battery pack accommodating positions 201 are formed in the shelf 20. Each battery pack accommodating position 201 is provided with a sliding fitting 21. The sliding member 30 can slide in and out of a battery pack accommodating position 201 and slidably fit with the sliding fitting 21.

[0040] Therefore, after the battery pack 900 is loaded on the sliding member 30, the sliding member 30 is slidably installed on the sliding fitting member 21 and slides toward the inside of the battery pack accommodating position 201, so that the sliding member 30 drives the battery pack 900 loaded thereon to slide into the battery pack accommodating position 201 accordingly, thereby realizing the assembly of the battery pack 900 on the shelf 20.

[0041] When the battery pack 900 is unloaded into the battery pack storage position 201, the sliding member 30 is slid toward the outside of the battery pack storage position 201, so that the sliding member 30 drives the loaded battery pack 900 to slide out of the battery pack storage position 201 accordingly, and then the battery pack 900 is unloaded from the shelf 20.

[0042] Optionally, the sliding fitting member 21 comprises a slide rail having a convex portion 211 . The sliding member 30 comprises a rollable rolling member, such as a roller, and the rolling member is provided with a slide groove 301 that is slidably matched with the convex portion 211 .

[0043] Thus, when the rolling element rolls on the surface of the slide rail, the rolling element slides along the extending direction of the slide rail. Moreover, the friction resistance encountered by the rolling element is small, which is conducive to loading and unloading the battery pack 900 with less effort.

[0044] The locking assembly 40 includes a follower 41 and a locking member 42. The follower 41 can be movably connected to the battery pack 900 as the battery pack 900 moves. The locking member 42 is disposed on the shelf 20 and is located on the moving path of the follower 41, so that when the follower 41 moves to a preset position with the battery pack 900, the locking member 42 cooperates with the follower 41 to lock and position the battery pack 900 in the battery pack accommodation position 201.

[0045] In other words, when the battery pack 900 is driven to slide, the follower 41 moves accordingly until the follower 41 slides to a predetermined position where it reaches the locking member 42, and the locking member 42 locks the follower 41. Thus, the position of the battery pack 900 in the battery pack accommodation position 201 is fixed.

[0046] In some examples of the present disclosure, the locking member 42 includes a stopper 421 and a screw. The stopper 421 is fixed to the shelf 20 and is located on the moving path of the follower 41 so as to stop against the follower 41 when the follower 41 moves to the preset position. The screw passes through the stopper 421 and extends into the follower 41 to be screw-locked.

[0047] Thus, the battery pack 900 is locked by the threaded connection between the stop seat 421 and the follower 41. When the battery pack 900 needs to be unloaded, the battery pack 900 can be unlocked by simply unscrewing the threaded member out of the follower 41 and the stop seat 421. The battery pack 900 is convenient to lock and unlock with high efficiency. However, it is understandable that the locking assembly 40 of the present disclosure includes but is not limited to this, and the locking member 42 and the follower 41 can also be locked and unlocked by electromagnetic magnetic attraction.

[0048] In the above process, since the battery pack 900 of the present disclosure is assembled and unloaded by sliding the sliding member 30 along the sliding fitting member 21, the friction resistance encountered when assembling and unassembling the battery pack 900 is small, the wear of the battery pack 900 is small, and the battery pack 900 is easy to assemble. Moreover, after assembly, the position of the battery pack 900 is fixed, and the battery pack 900 is not easy to move after assembly, and the assembly is stable.

[0049] Optionally, see Figure 2 The plurality of battery pack accommodation positions 201 are arranged at intervals in the vertical direction, and each layer of the battery pack accommodation positions 201 includes a plurality of brackets 22. The plurality of brackets 22 are arranged at intervals in the horizontal direction, and a sliding fitting 21 is arranged above each bracket 22.

[0050] Optionally, see Figure 2 The battery compartment further includes a position limiting bearing frame 50. The position limiting bearing frame 50 is installed below the battery pack 900, surrounds the battery pack 900, and has a plurality of sliding members 30 corresponding to the plurality of sliding matching members 21 disposed thereunder.

[0051] In a specific example, there are two brackets 22 , and the two brackets 22 are arranged at intervals in the horizontal direction. Two sliding members 30 are arranged below the position limiting bearing frame 50 , and the two sliding members 30 are arranged in a one-to-one correspondence with the two sliding matching members 21 .

[0052] See also Figure 1 The storage bin 10 for the energy storage system includes a bin body 11, a door body 12 and a door opening assembly 13.

[0053] See also Figure 2 and Figure 3 The storage cavity 1101 is formed on the warehouse body 11, and a door opening 1102 communicating with the storage cavity 1101 is formed on the side of the warehouse body 11. The door body 12 is hinged to the warehouse body 11 to open / close the door opening 1102, and a vertically penetrating rotation hole 1201 is provided on the surface of the door body 12.

[0054] Thus, when the door body 12 rotates toward the storage cavity 1101 , the door opening 1102 is closed by the door body 12 , and when the door body 12 rotates toward the storage cavity 1101 , the door opening 1102 is opened by the door body 12 .

[0055] It is understandable that in order to ensure the sealing between the edge of the door body 12 and the warehouse body 11 and prevent external impurities such as rainwater from entering the warehouse body 11 through the gap between the door body 12 and the warehouse body 11, the door body 12 will be installed in the door opening 1102 in an approximately sealed manner. However, this will make it difficult for the door body 12 to separate from the door opening 1102 when it is opened, making it inconvenient to open the door body 12.

[0056] See also Figure 3 and Figure 4 The door opening assembly 13 includes a door opening rod 131 and an operating component 132. The door opening rod 131 includes a rod portion 1311 and a resisting portion 1312. The rod portion 1311 is rotatably inserted into the rotating hole 1201, and the resisting portion 1312 is formed by extending outward from the outer side wall of the rod portion 1311, and is arranged corresponding to the warehouse body 11, and is configured to abut against the warehouse body 11 when it is driven by the rod portion 1311 to rotate to a preset position, so as to drive the door body 12 to move out of the storage cavity 1101 and away from the door opening 1102 under the action of the continued rotation of the rod portion 1311. The operating component 132 can drive the door opening rod 131 to be rotatably connected to the door opening rod 131.

[0057] Thus, when the operating member 132 drives the rod 1311 to rotate, the abutting portion 1312 will be driven by the rod 1311 to rotate to a position abutting against the bin body 11. After that, when the rod 1311 continues to be driven to rotate, the rod 1311 will further rotate with the abutting point between the abutting portion 1312 and the bin body 11 as the rotation fulcrum, so that the rod 1311 can use the force to drive the door body 12 to rotate away from the storage cavity 1101, thereby causing the door body 12 to be pulled outward in a manner similar to being pried. For a specific example, refer to Figure 3 and Figure 4When the operating member 132 rotates counterclockwise in the horizontal plane, thereby driving the rod 1311 to rotate counterclockwise around the vertical axis, the abutment portion 1312 is driven by the rod 1311 to rotate counterclockwise to a position abutting against the bin body 11. After that, when the rod 1311 is driven to continue to rotate counterclockwise, the rod 1311 can use the abutment point to drive the door body 12 to rotate away from the storage cavity 1101, thereby causing the door body 12 to be pulled outward in a manner similar to being pried, thereby allowing the door body 12 of the present disclosure to be conveniently and easily opened.

[0058] It is understandable that the rod portion 1311 and the abutting portion 1312 may be formed integrally or detachably connected.

[0059] Optionally, the operating component 132 includes a door handle. The door handle is connected to the rod 1311, and the contacting parts of the door handle and the contacting part 1312 are relatively arranged on both sides of the rod 1311. In this way, when the door handle drives the door rod 131 to rotate, the distance between the operating end of the door handle and the contacting point is longer, and the force arm is longer. Therefore, when the door handle rotates to drive the door body 12 to rotate away from the door opening 1102, less force is used, which can save effort.

[0060] See also Figure 3 and Figure 5 The door opening assembly 13 further includes a position limiting receiving seat 133. The position limiting receiving seat 133 is disposed on the door body 12, and the position limiting receiving seat 133 is formed with a transversely penetrating receiving hole 13301. The hole wall of the receiving hole 13301 is formed with a receiving inlet and outlet 13302 opening upward.

[0061] The operating component 132 is at least partially disposed in the storage hole 13301 and is connected to the door opening rod 131 so as to be rotatable up and down to enter and exit the storage inlet and outlet 13302, and the operating component 132 can be horizontally rotated to drive the door opening rod 131 to rotate.

[0062] Thus, before the door body 12 is opened, the operating member 132 is stored in the storage hole 13301. When the door body 12 needs to be opened, the operating member 132 is rotated upward so that the operating member 132 can be disengaged from the storage inlet and outlet 13302, and then the operating member 132 can be rotated horizontally to drive the door opening rod 131 to rotate. In this way, when the door body 12 is not opened, the operating member 132 will not be accidentally touched to cause the door body 12 to open.

[0063] Optionally, see Figure 5The door opening assembly 13 further includes an in-and-out blocking member 134. The in-and-out blocking member 134 is movably disposed on the position-limiting storage seat 133 between a blocking position capable of blocking the operating member 132 from entering and exiting the storage inlet and outlet 13302 and a smooth position allowing the operating member 132 to enter and exit smoothly.

[0064] That is, when the operating component 132 is not needed, the inlet and outlet blocking member 134 is located at the blocking position, and the operating component 132 can be blocked by the inlet and outlet blocking member 134, so that it cannot escape from the storage access 13302. When the operating component 132 is needed, the inlet and outlet blocking member 134 is moved to the unblocked position. Since the operating component 132 is no longer blocked by the inlet and outlet blocking member 134 when it is located at the unblocked position, the operating component 132 can be smoothly escaped from the storage access 13302 and then used.

[0065] Specifically, the inlet and outlet blocking member 134 is rotatably disposed on the position-limiting receiving seat 133. Thus, the inlet and outlet blocking member 134 can be rotated upward to the unblocked position to no longer block the operating member 132 from being moved out of the receiving inlet and outlet 13302. Alternatively, the inlet and outlet blocking member 134 can be rotated downward to block the operating member 132 from being moved out of the receiving inlet and outlet 13302.

[0066] Optionally, see Figure 5 , the door opening assembly 13 further includes an adapter 135 and a horizontal rotation shaft 136. The adapter 135 is fixedly mounted on the door opening rod 131. A rotation channel 13501 having a side opening 13502 is formed in the adapter 135. The horizontal rotation shaft 136 is disposed in the rotation channel 13501. The operating component 132 extends into the rotation channel 13501 through the side opening 13502, and is rotatably mounted on the outside of the horizontal rotation shaft 136 to rotate up and down. Thus, the operating component 132 can rotate up and down relative to the door opening rod 131.

[0067] In some embodiments of the present disclosure, see Figure 4 and Figure 6 The storage bin 10 further includes a lock seat 137. The lock seat 137 is disposed in the bin body 11, and a vertically penetrating lock hole 13701 is formed in the lock seat 137, and a locking inlet and outlet 13702 is formed on the hole wall of the lock hole 13701. The abutment portion 1312 is disposed in the lock hole 13701 so as to be at least partially rotatable in and out of the locking inlet and outlet 13702.

[0068] In other words, when the door body 12 is closed, the abutment 1312 of the door opening rod 131 can be limited in the lock hole 13701 and then locked by the lock hole 13701, thereby maintaining the closed state of the door body 12. When the door body 12 is opened, as the abutment 1312 is driven to rotate, the abutment 1312 can abut against the lock seat 137 to form a rotation fulcrum, and when the abutment 1312 continues to rotate, the abutment 1312 can at least partially escape from the locking inlet and outlet 13702, thereby making it convenient for the door body 12 to be further opened later.

[0069] It is understandable that the lock seat 137 may not be provided in the present disclosure. When the lock seat 137 is not provided, the abutment portion 1312 directly abuts against the warehouse body 11 during rotation to achieve leverage.

[0070] Optionally, the abutment portion 1312 forms a guide curved surface 13121 suitable for rotationally abutting against the surface of the seat body 1371. Specifically, the guide curved surface 13121 protrudes toward the seat body 1371, and during the rotation of the abutment portion 1312, the abutment portion 1312 can at least partially escape from the locking inlet and outlet 13702 through the guidance of the guide curved surface 13121, thereby allowing the abutment portion 1312 to at least partially rotate in and out of the locking inlet and outlet 13702.

[0071] Optionally, see Figure 4 and Figure 6 , the abutment portion 1312 forms a first limiting socket 131201 and a second limiting socket 131202. The lock seat 137 includes a seat body 1371, a first limiting convex body 1372 and a second limiting convex body 1373. The first limiting convex body 1372 is disposed on the seat body 1371, and the first limiting convex body 1372 is plugged into and matched with the first limiting socket 131201. The second limiting convex body 1373 and the first limiting convex body 1372 are located on opposite sides of the lock hole 13701, and are plugged into and matched with the second limiting socket 131202.

[0072] Therefore, through the above-mentioned arrangement, the lock seat 137 realizes the limitation of the resistance part 1312 in the up and down and left and right directions, so that after the door body 12 is closed, the door opening rod 131 cannot move in the up and down and left and right directions, thereby making the door opening rod 131 stable when the door is not opened.

[0073] Specifically, the first limiting socket 131201 is open on one side and closed on the other side, and the inner diameter of the first limiting socket 131201 gradually decreases from the open side to the closed side of the first limiting socket 131201. The second limiting socket 131202 is open on one side and closed on the other side, and the open side of the second limiting socket 131202 and the open side of the first limiting socket 131201 are located on opposite sides of the rod 1311, and the inner diameter of the second limiting socket 131202 gradually decreases from the open side to the closed side of the second limiting socket 131202. Therefore, the first limiting protrusion 1372 and the second limiting protrusion 1373 are conveniently inserted into and separated from the first limiting socket 131201 and the second limiting socket 131202.

[0074] Optionally, the lock seat 137 further includes a blocking hook 1374. The blocking hook 1374 is formed to extend downward from one end of the second limiting protrusion 1373 away from the seat body 1371, so as to form a blocking socket 137401 suitable for inserting at least part of the abutment portion 1312 between the blocking hook 1374 and the seat body 1371. Thus, through the above arrangement, the lock seat 137 realizes the limitation of the abutment portion 1312 in the front-to-back direction, so that after the door body 12 is closed, the door opening rod 131 is also immobile in the front-to-back direction, thereby further enhancing the stability of the door opening rod 131 when the door is not opened.

[0075] See also Figure 2 and Figure 7 The storage bin 10 is provided with at least one vent connected to the storage cavity 1101 and the external environment. Specifically, the vent includes a first vent 1103 and a second vent 1104. The first vent 1103 is provided on the side of the bin body 11. The second vent 1104 is provided on the surface of the bin body 11 away from the door opening 1102. Thus, the harmful gas in the storage bin 10 can be discharged through the vent.

[0076] See also Figure 1 The storage bin 10 is provided with an exhaust grille 1105 communicating with the storage cavity 1101 and the external environment. The battery compartment further includes an exhaust fan. The exhaust fan is arranged in the storage cavity 1101 and located at the exhaust grille 1105. Thus, harmful gases and heat in the storage bin 10 can be discharged through the exhaust grille 1105.

[0077] See also Figure 1 and Figure 2 The present disclosure further provides an energy storage system, which includes the battery compartment and the battery pack 900 as described above. The battery pack 900 is arranged in the storage compartment 10.

[0078] See also Figure 2 and Figure 8 , the energy storage system also includes a monitoring component 60, a negative state elimination component 70 and a controller 80. The monitoring component 60 is arranged in the storage cavity 1101 to monitor the battery pack 900. The negative state elimination component 70 is at least partially arranged in the storage cavity 1101, and is used to eliminate the negative state of the battery pack 900, such as the state due to the increase in temperature during long-term operation or the state due to accidental fire. The controller 80 is respectively connected to the monitoring component 60 and the negative state elimination component 70, and is used to trigger the negative state elimination component 70 to perform an elimination action until the negative state of the battery pack 900 is eliminated when the monitoring component 60 detects that the battery pack 900 is in a negative state. This arrangement can ensure that the battery pack 900 is stably in a normal working state and ensure the working reliability of the energy storage system.

[0079] Optionally, the monitoring component 60 includes a temperature detector 61 and / or a smoke detector 62 to monitor whether the temperature of the battery pack 900 is too high, for example, exceeds a set threshold and / or catches fire. The negative state elimination component 70 includes a cooling unit 71 and / or a fire fighting unit 72 to be triggered to perform cooling actions and / or fire fighting actions when it is detected that the temperature of the battery pack 900 is too high and / or catches fire.

[0080] Specifically, the cooling unit 71 is a water chiller, which can maintain a constant temperature of the battery pack 900, reduce the temperature difference of the battery pack 900 during use, protect the battery pack 900, and extend the service life of the battery pack 900.

[0081] Specifically, the fire fighting unit 72 includes a jet fire fighting device and a water fire fighting device. When the battery pack 900 is detected to be overheated and smoke is detected, the jet fire fighting device and the water fire fighting device are triggered to spray fire fighting gas and fire fighting water into the storage cavity 1101 to fight the fire.

[0082] Therefore, when the temperature of the battery pack 900 is too high and / or a fire occurs, the negative state elimination component 70 can cool the battery pack 900 and / or extinguish the fire of the battery pack 900, thereby eliminating the negative state.

[0083] For specific examples, see Figure 1 and Figure 2The storage chamber 1101 in the storage bin 10 is divided into a battery chamber and an electrical chamber. The battery chamber stores the battery pack 900. The electrical chamber stores the negative state elimination component 70, such as the chiller 71 and the fire fighting unit 72. The battery chamber and the electrical chamber are both provided with the door body 12.

[0084] The door body 12 corresponding to the battery cavity is a double-opening door, which is hinged to the warehouse body 11 through hinges, and each door body 12 of the double-opening door is provided with two sets of door opening components 13.

[0085] The door body 12 corresponding to the electrical cavity is a single-opening door, which is hinged to the warehouse body 11 through hinges, and a group of door opening components 13 are provided on the single-opening door.

[0086] Optionally, the monitoring component 60 further includes a camera 63. Thus, the staff can remotely observe the overall state of the battery compartment through the camera 63 to prevent the staff from being unable to observe the internal situation from the outside.

[0087] Optionally, see Figure 1 and Figure 8 The energy storage system further includes a display 90. The display 90 is disposed on the outer surface of the door body 12 and is connected to the controller 80 for displaying information monitored by the monitoring component 60, such as temperature.
