The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] The utility model embodiment provides an energy storage battery cabinet, such as Figure 1-Figure 8 As shown, the energy storage battery cabinet comprises:

[0042] A box body 100, wherein the interior of the box body 100 is divided into a battery compartment 110 and a device compartment 120;

[0043] A battery rack 200, wherein a roller 250 is provided at the bottom of the battery rack 200, and a plurality of placement bins are provided on the battery rack 200, wherein the battery modules 300 are arranged in the placement bins;

[0044] A central control device 400, which is disposed in the device compartment 120 and is electrically connected to the battery module 300;

[0045] The battery rack 200 is provided with a heat dissipation module, and the battery rack 200 on which the battery module 300 is placed can be removed from the battery compartment 110. When performing maintenance, a pad 600 can be used to construct a platform on the box 100, and the battery rack 200 can be pulled out as a whole. The operator does not need to lift the battery module after the battery module is pulled out, and the battery module can be directly inspected and maintained. At the same time, the heat dissipation module can be maintained and repaired, which reduces the difficulty of disassembling and maintaining the equipment;

[0046] In the present application, the battery rack 200 and the battery compartment 110 are split structures, and the battery rack 200 is integrated with a heat dissipation module. When the battery rack 200 takes out the battery module 300, the heat dissipation module will also be moved out synchronously, and the heat dissipation module can be inspected and maintained accordingly. The battery rack 200 is provided with a first placement bin 241, a second placement bin 242, a third placement bin 243 and a fourth placement bin 244, and the first placement bin 241, the second placement bin 242, the third placement bin 243 and the fourth placement bin 244 are formed by dividing the main structure of the battery rack 200, and the main structure of the battery rack 200 is used to form a support frame, so as to support the battery module 300;

[0047] In this embodiment, the function of the box body 100 is to form a closed space to isolate the external environment. There is no need to design a bearing structure like a traditional battery cabinet structure. Here, the box body 100 is divided into two parts. One part is a battery compartment 110. The end face of the battery compartment 110 is provided with a placement opening. The outer side of the placement opening is provided with a flat door body. The battery rack enters and exits the battery compartment 110 from the placement opening after the door body is opened; the other part is an equipment compartment 120, in which an external control center, a battery energy storage system and other auxiliary Auxiliary equipment and other control elements are used to monitor the battery module 300 on the battery rack 200. Since the battery rack 200 is not in direct contact with the battery compartment 110, the side wall of the battery compartment 110 is provided with a plurality of sliding guide rails 130, and the sliding guide rails 130 are in contact with the sliding contacts provided on the battery rack 200. The sliding guide rails 130 and the sliding contact technology here adopt the technical principle of the sliding contact line in the prior art to meet the need for electrical connection during the sliding process; the sliding contact is electrically connected to the battery module 300;

[0048] In the present application, the box 100 can be arranged in parallel by a plurality of battery compartments 110, and each battery module 300, namely PACK, is composed of a battery, an excitation fuse FU1 and a pack control module. Figure 8Battery energy storage system architecture diagram, #1PACK, #2PACK...#nPACK are connected through copper bus 12...copper bus 1n respectively, #1RACK also includes a rack control module and an excitation fuse FU2, #1PACK is connected to the excitation fuse FU2 through copper bus 11, and such a connection constitutes #1RACK. The rack control module can collect information such as voltage and current and issue control instructions. The battery energy storage system includes several similar RACKs, named #2RACK...#m RACK, and each RACK is connected to the busbar of the connecting equipment compartment 120 through copper bus 2 to complete the busbar.

[0049] In addition, each pack control module can collect the temperature and voltage of the pack and control the on-off of the excitation fuse FU1. Each pack control module communicates with the external control center, and the external control center can issue control instructions. The entire control module is powered by an uninterruptible power supply, which can be any suitable voltage level and type. The uninterruptible power supply and the external control center are set in the equipment compartment 120;

[0050] The specific implementation of the battery energy storage system is as follows:

[0051] When the energy storage system is operating normally, the pack control module continuously collects temperature and voltage information of each pack, and performs data analysis and reporting. The rack control module continuously collects current, temperature and other information, and performs data analysis and reporting. When the temperature change is numerically recorded, it is monitored through the rack control module. When the current data is monitored to increase sharply, it is generally caused by a short circuit fault. The corresponding PACK temperatures should be compared and analyzed immediately. If the circuit current disappears after a period of time, it can be determined that the excitation fuse FU2 has played a protective role and disconnected the faulty circuit. At this time, the control module only records the data and does not control the disconnection of the excitation fuse FU1;

[0052] If the short-circuit current duration exceeds the set value and still exists, it is determined that the excitation fuse FU2 does not play a corresponding protective role. At this time, the disconnection designation should be reached based on the current between different RACKs and the temperature change speed and average temperature rise of each PACK: specifically:

[0053] The external control center immediately issues a control to disconnect the excitation fuse FU2 in the 1#PACK in the RACK with the largest abnormal current, and then immediately determines whether the abnormal current disappears. If the fault current disappears, it means that the fault point has been cut off and isolated. If the fault current still exists, the excitation fuse FU2 in the 1#PACK in the RACK with the maximum fault current will continue to be controlled to be cut off until the fault current disappears. In the judgment process, the collected values ​​of each temperature are used as auxiliary judgment criteria. The point with a large through-current value always has a more severe temperature rise.

[0054] When a short circuit fault occurs inside a PACK, the temperature of individual PACKs rises sharply. At this time, the rack control module of the RACK where the abnormal PACK is located combines with the RACK to collect current. If the current exceeds the threshold, the rack control module cuts off the excitation fuse FU2 in the abnormal PACK and its adjacent PACKs, as well as the excitation fuse FU2 on the 1# PACK in the abnormal RACK, thereby disconnecting the abnormal RACK and isolating the two sides of the abnormal PACK.

[0055] Therefore, when the excitation fuse FU1 and the excitation fuse FU2 are blown or fail, when the battery rack 200 structure in the present application is used to arrange the PACK, the disassembly can be completed quickly, and the designated excitation fuse FU1 and the excitation fuse FU2 can be quickly reached, and the faulty and abnormal equipment can be repaired and maintained in time, thereby improving the maintenance efficiency of the container battery equipment;

[0056] As a preferred implementation in this embodiment, the battery rack 200 includes a rear box body 210, several groups of carrying plates 230 and several groups of columns 220, the carrying plates 230 are arranged between the columns 220, and the multiple groups of carrying plates 230 divide the battery rack 200 away from the rear box body 210 into a first placement bin 241, a second placement bin 242, a third placement bin 243 and a fourth placement bin 244, and a group of battery modules 300 are placed in the first placement bin 241, the second placement bin 242, the third placement bin 243 and the fourth placement bin 244 respectively, and different battery modules 300 are connected in series with each other and connected to the external control center battery module through sliding contacts;

[0057] In this embodiment, the first placement bin 241 is provided with mounting rails 270, and the mounting rails 270 are four groups respectively arranged at the corners around the first placement bin 241, and the battery module 300 is assembled between the mounting rails 270; the mounting rails 270 are used to form a limiting guide for the battery module 300, so as to facilitate assembly and quickly insert the battery module 300;

[0058] The cross section of the mounting rail 270 described here can adopt an L-shaped structure or a long strip structure. The L-shaped structure allows the battery module 300 to be mounted above the carrier plate 230 during assembly without direct contact with the carrier plate 230, thereby reducing the resistance during the push-pull process of the disassembly process, while the long strip structure directly clamps and limits the battery module 300, and the surface of the battery module 300 directly contacts the carrier plate 230. Such a structure allows the surface of the battery module 300 to directly contact the carrier plate 230, and the heat dissipation is completed faster under the action of the heat dissipation structure provided inside the carrier plate 230. In this application, an L-shaped mounting rail 270 is used for structural description;

[0062] In this embodiment, the cooling unit adopts the existing technical equipment and is mainly composed of a compressor, a condenser and an expansion valve. The condensation principle here is similar to that of a refrigerator. The refrigerant flowing in the heat dissipation coil 530, the liquid inlet pipe 510 and the liquid outlet pipe 520 is pressurized and condensed by the compressor to form a liquid that enters the liquid inlet pipe 510, and then is transported to different heat dissipation coils 530 by the liquid inlet pipe 510. After completing the heat absorption, the refrigerant will return to the compressor through the liquid outlet pipe 520; the cooling unit provides a cold source for the heat dissipation coil 530; the rear box body 210 and the box body 100 are provided with a heat dissipation port of the condenser; the heat is promptly exported from the box body 100;

[0067] The third slide bar 263 includes a third base plate 2631 and a second slide rail 2632. The second slide rail 2632 is disposed on the third base plate 2631. The end surface of the third base plate 2631 away from the second slide rail 2632 is fixed to the inner wall of the battery compartment 110. The second slide rail 2632 slides in the second slide groove 2622.
