Technical Field
[0001] This utility model relates to the field of energy storage equipment technology, and in particular to an energy storage control cabinet and an energy storage container. Background Technology
[0002] Traditional energy storage container layouts consist of clusters of battery packs and high-voltage boxes. The power distribution section, liquid cooling unit, and fire suppression system are arranged separately. As the capacity of a single container increases, the internal space of the energy storage container becomes increasingly tight. If the power distribution section, liquid cooling unit, and fire suppression system are still distributed separately as in traditional energy storage containers, it will result in wasted space. Furthermore, this distribution method will lead to complex wiring and a significantly increased risk of short circuits due to insulation damage. Utility Model Content
[0003] One aspect of this utility model provides an energy storage control cabinet that integrates a busbar control module, a fire protection module, a power distribution control module, and a liquid cooling unit. This greatly improves the space utilization rate inside the energy storage container, optimizes the internal layout of the energy storage container, simplifies the wiring of the energy storage container, and reduces the risk of short circuits.
[0004] Another aspect of this utility model provides an energy storage container with high space utilization, reasonable internal layout, simple wiring, high operational reliability, and low failure rate.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] An energy storage control cabinet includes: a cabinet body, wherein the cabinet body has a first cavity, a second cavity, a third cavity, and a fourth cavity arranged separately, the first cavity, the second cavity, and the third cavity being located below the fourth cavity; a busbar control module, the busbar control module being installed in the first cavity and electrically connected to the battery pack of the energy storage container; a fire-fighting module, the fire-fighting module being installed in the second cavity; a power distribution control module being installed in the third cavity and electrically connected to the battery pack and the busbar control module; and a liquid cooling unit, the liquid cooling unit being installed in the fourth cavity and used to deliver a cooling medium toward the battery pack.
[0007] An energy storage container includes a container body and an energy storage control cabinet as described above. The container body includes a battery compartment and a control compartment. The battery compartment contains multiple battery packs, and the energy storage control cabinet is installed in the control compartment.
[0008] The beneficial effects of this utility model are as follows: The energy storage control cabinet is internally divided into a first cavity, a second cavity, a third cavity, and a fourth cavity. The busbar control module is installed in the first cavity, the fire-fighting module in the second cavity, the power distribution control module in the third cavity, and the liquid-cooled unit in the fourth cavity. During installation, the entire energy storage control cabinet can be assembled, installed into the container, and connected to the battery pack. Compared to the existing technology where the busbar, power distribution, liquid-cooled unit, and fire-fighting control unit are separately arranged in the container, this utility model integrates the busbar control module, fire-fighting module, power distribution control module, and liquid-cooled unit into a single cabinet. This significantly improves the space utilization rate inside the energy storage container, optimizes the internal layout of the energy storage container, simplifies the wiring, and reduces the risk of short circuits.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0016] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0018] This utility model discloses an energy storage control cabinet, referencing... Figures 1 to 3 As shown, the device includes a cabinet 100, a busbar control module 200, a fire suppression module 300, a power distribution control module 400, and a liquid cooling unit. The cabinet 100 has four compartments: a first cavity 101, a second cavity 102, a third cavity 103, and a fourth cavity. The first cavity 101, the second cavity 102, and the third cavity 103 are all located below the fourth cavity. The busbar control module 200 is installed in the first cavity 101 and is electrically connected to the battery pack of the energy storage container. The fire suppression module 300 is installed in the second cavity 102. The power distribution control module 400 is installed in the third cavity 103 and is electrically connected to the battery pack and the busbar control module 200. The liquid cooling unit is installed in the fourth cavity and is used to deliver cooling medium to the battery pack. It is understandable that, since the cabinet 100 is internally divided into a first cavity 101, a second cavity 102, a third cavity 103, and a fourth cavity, and the busbar control module 200 is installed in the first cavity 101, the fire-fighting module 300 is installed in the second cavity 102, the power distribution control module 400 is installed in the third cavity 103, and the liquid cooling unit is installed in the fourth cavity, during installation, the entire energy storage control cabinet can be assembled and installed into the container 700 and connected to the battery pack. Compared with the existing technology, where the busbar, power distribution, liquid cooling unit, and fire-fighting host 301 are separately arranged in the container 700, the energy storage control cabinet of this utility model integrates the busbar control module 200, the fire-fighting module 300, the power distribution control module 400, and the liquid cooling unit into one cabinet 100, which greatly improves the space utilization rate inside the energy storage container, optimizes the internal layout of the energy storage container, simplifies the wiring of the energy storage container, and reduces the risk of short circuits.
[0019] Optionally, the busbar control module 200 includes a master control BMS (Battery Management System) module 201, which is installed on the side wall of the first cavity 101 and electrically connected to the battery pack. It is understood that the battery pack in the energy storage container is typically configured as multiple battery clusters, each battery cluster including multiple battery boxes arranged vertically from top to bottom. Each battery box is equipped with a slave control BMS module. The master control BMS module 201 of the busbar control module 200 electrically connects to the multiple slave control BMS modules of each battery cluster via wires, thereby enabling one master control BMS module 201 to control one battery cluster. In this embodiment, there are eight master control BMS modules 201, meaning that the corresponding energy storage container contains eight battery clusters. Of course, in other embodiments of this invention, the number of master control BMS modules 201 can be adjusted according to actual needs.
[0020] Optionally, the busbar control module 200 also includes a display control panel 202, which is mounted on the front wall of the cabinet 100 and electrically connected to the main control BMS module 201. Understandably, through the display control panel 202, operators can monitor the battery pack's operating status and related control parameters in real time, and also adjust the operating status of the main control BMS module 201 as needed. The specific model of the display control panel 202 and its connection method with the main control BMS module 201 can be selected based on actual needs and existing technology. It should be noted that the cabinet 100 is usually a cuboid. The surface of the cabinet 100 that contacts the ground is the bottom wall, and the top wall is set accordingly. The main control BMS (Battery Management System) module is installed on the top wall. The main control BMS module 201 is installed on the surface of the first cavity 101, which is the right side wall of the cabinet. The left side wall is set accordingly. Of the remaining two side walls, one side wall is provided with an openable cabinet door. The side wall with the cabinet door is the front side wall of the cabinet 100, and the corresponding side wall is the rear side wall.
[0021] Optionally, a first fixing structure 1011 is provided on the side wall of the first cavity 101, and a fixing post is provided on the first fixing structure 1011. The main control BMS module 201 is fixed to the fixing post by a first fixing member. It is understood that the first fixing member can be a screw, a pin, or other connecting parts as needed. Fixing the main control BMS module 201 to the first fixing structure 1011 by the first fixing member ensures the installation stability of the main control BMS module 201. It should be noted that the first fixing structure 1011 can be a fixing beam, and the two ends of the fixing beam can be fixed to the two opposite side walls of the first cavity 101 by screw connection, welding, or other methods. Of course, in other embodiments of this utility model, the first fixing structure 1011 can also be other structures as needed, and is not limited to the structure of a fixing beam.
[0022] Optionally, the bus control module 200 also includes a pre-charge contactor 203 and a pre-charge resistor 204, both of which are electrically connected to the main control BMS module 201. Understandably, the core function of the pre-charge resistor 204 is to safely charge the bus capacitor of the main control BMS module 201 in the initial power-up phase, working in conjunction with the pre-charge contactor 203. By limiting the initial current, the pre-charge contactor 203 and the pre-charge resistor 204 act as a "safety valve," effectively preventing the destructive impact of surge current on the circuitry of the main control BMS module 201, ensuring a smooth soft start of the main control BMS module 201, improving operational reliability, and reducing the failure rate.
[0023] Optional, see reference Figure 2As shown, the bus control module 200 also includes a first conductive element 205, a second conductive element 206, a Hall sensor 207, a DC fuse 208, and a DC disconnect switch 209. The first conductive element 205, the second conductive element 206, the Hall sensor 207, and the DC fuse 208 are all arranged in pairs. One end of the paired first conductive element 205 is electrically connected to the positive and negative output terminals of the battery pack. The paired first conductive elements 205 are correspondingly electrically connected to the paired DC fuses 208. The paired DC fuses 208 are electrically connected to the positive and negative terminals of the DC disconnect switch 209. The DC disconnect switch 209 is used to connect to the PCS module (Power Conversion System). The paired Hall sensors 207 are correspondingly arranged on the paired first conductive elements 205. It is understandable that the PCS module is responsible for bidirectional conversion and control of electrical energy, serving as a crucial electrical bridge connecting the energy storage container to the power grid / load. In this embodiment, by installing a DC fuse 208 and a DC disconnect switch 209 between the battery pack and the PCS module, the connection between the battery pack and the PCS module is promptly severed when the battery pack malfunctions, providing effective protection for the power grid or load. The first conductive element 205 and the second conductive element 206 can be selected to connect to conductive structural components such as copper busbars according to actual needs. The Hall sensor 207 can measure the current magnitude by detecting changes in the magnetic field caused by changes in the direction and magnitude of the current, thereby enabling real-time monitoring of the current in the output / input circuits of the battery pack, which is beneficial for operators to monitor the operating status of the battery pack.
[0024] Optionally, the bus control module 200 includes a third conductive element 210. These third conductive elements 210 are arranged in pairs, with one end electrically connected to the positive and negative output terminals of the DC disconnect switch 209, respectively, and the other end electrically connected to the PCS module. It is understood that using the third conductive element 210 to connect the DC disconnect switch 209 and the PCS module ensures a stable electrical connection between them, simplifies wiring, and reduces the failure rate. The third conductive element 210 can be connected to conductive structural components such as copper busbars, depending on actual needs.
[0025] Optionally, the first cavity 101 further includes a second fixing structure 1012. The two ends of the second fixing structure 1012 are fixedly connected to two opposite side walls of the first cavity 101. The DC disconnect switch 209 is mounted on the second fixing structure 1012 via a second fixing member. It is understood that the second fixing member can be a screw, a pin, or other connecting member as needed. Fixing the DC disconnect switch to the second fixing structure 1012 via the second fixing member ensures the installation stability of the DC disconnect switch 209. It should be noted that the second fixing structure 1012 can be a fixing beam. The two ends of the fixing beam can be fixed to the two opposite side walls of the second cavity 102 via screws, welding, or other methods. Of course, in other embodiments of this utility model, the second fixing structure 1012 can also be other structures as needed, and is not limited to the structure of a fixing beam.
[0026] Optionally, the bus control module 200 includes a switching power supply 211, which is electrically connected to the DC disconnect switch 209. It is understood that the switching power supply 211 supplies power to the DC disconnect switch 209 to ensure its stable operation. The specific type of switching power supply 211 can be selected according to actual needs. The switching power supply 211 can be fixed to the side wall of the first cavity 101 by means of screw connection, snap-fit connection, etc., and the specific connection method can be selected according to actual needs.
[0027] Optionally, the bus control module 200 also includes a DC surge protector 212, which is electrically connected to the DC disconnect switch 209. It is understood that the added DC surge protector 212 enables the bus control module 200 to perform surge protection. The type of DC surge protector 212 can be selected according to actual needs. The DC surge protector 212 can be fixed to the side wall of the first cavity 101 by means of screw connection, snap-fit connection, etc., and the specific connection method can be selected according to actual needs.
[0028] Optionally, the energy storage control cabinet includes a dehumidifier 500, which is installed inside the first chamber 101. It is understood that by installing the dehumidifier 500 inside the first chamber 101, the dehumidifier 500 ensures a relatively dry environment within the first chamber 101, thereby ensuring that the combiner control module 200 operates in a relatively dry environment and reducing the failure rate. The dehumidifier 500 can be fixed to the side wall of the first chamber 101 by means of screws, clips, or other methods; the specific connection method can be selected according to actual needs.
[0029] Optionally, the energy storage control cabinet also includes a liquid-cooled heat dissipation structure 600, which is connected to the liquid-cooled unit. The cooling medium circulates between the liquid-cooled heat dissipation structure 600 and the liquid-cooled unit. The liquid-cooled heat dissipation structure 600 is located at the lower part of the first cavity 101. First, it should be noted that current traditional energy storage containers generally use air-cooled heat dissipation for their internal electrical components. The high-voltage box in the energy storage container typically uses multiple fans added to specific locations inside the high-voltage box after thermal simulation. These fans drive airflow, and heat is removed through convection heat exchange between the air and the surfaces of the electrical components inside the high-voltage box. The power distribution compartment of the energy storage container also generally uses a wall-mounted air-cooled air conditioner and air-cooled heat dissipation channels. This air-cooling method has a low thermal conductivity and limited heat dissipation efficiency. Under high power density or high temperature environments, the heat dissipation effect is poor and cannot meet the heat dissipation requirements of electrical components. At the same time, the operation of fans and wall-mounted air conditioners generates noise and consumes electricity over long periods. Furthermore, if the fans inside the high-voltage box are damaged or the heat dissipation channels are clogged, maintenance becomes difficult.
[0030] In the technical solution of this utility model, by setting a liquid cooling heat dissipation structure 600 connected to the liquid cooling unit in the first cavity 101, compared with the air cooling heat dissipation structure in the prior art, the liquid cooling heat dissipation structure 600 has high heat dissipation efficiency, can remove more heat, can effectively control the temperature of electrical components, and can control the temperature difference within a small range, which is conducive to improving the working stability and consistency of electrical components.
[0031] Optionally, the liquid cooling structure 600 includes copper tube fins 610 and a fan 620. A third fixing structure 1013 is located within the first cavity 101. The fan 620 is fixed to the third fixing structure 1013 via a third fixing member, and the copper tube fins 610 are positioned above the fan 620. Understandably, during actual operation, the cooling medium circulates between the copper tube fins 610 and the liquid cooling unit. The fan 620 accelerates the airflow within the first cavity 101 and rapidly diffuses the cooling energy from the copper tube fins 610 into the first cavity 101, thereby further enhancing the heat dissipation effect of the liquid cooling structure 600. Simultaneously, the third fixing member can be a screw, a pin, or other connecting parts as needed. Fixing the flow isolation switch to the third fixing structure 1013 via the third fixing member ensures the installation stability of the liquid cooling structure 600. It should be noted that the third fixing structure 1013 can be a fixing beam, and the two ends of the fixing beam can be fixed to the two opposite side walls of the first cavity 101 by means of screw connection, welding or other methods. Of course, in other embodiments of this utility model, the third fixing structure 1013 can also be selected from other structures according to actual needs, and is not limited to the structural form of a fixing beam.
[0032] Alternatively, the liquid cooling structures 600 are arranged in pairs, with the airflow driven by the fans 620 of the two paired liquid cooling structures 600 in opposite directions. Thus, one fan 620 draws air in and the other blows air out, enabling the airflow to form a stable clockwise or counterclockwise flow within the first cavity 101, which helps to improve the heat dissipation effect of the liquid cooling structure 600.
[0033] It should be noted that the specific types of copper tube fins 610 and fans 620 can be selected according to actual needs.
[0034] Optionally, the fire protection module 300 includes a fire control panel 301, a fire control box 302, a fire junction box 303, and a fire accessory box 304. The fire control panel 301 outputs fire protection medium towards the battery pack. The fire control box 302 is installed on the side wall of the second cavity 102 and is electrically connected to the fire control panel 301. The fire junction box 303 is installed on the side wall of the second cavity 102 and is electrically connected to both the fire control panel 301 and the fire control box 302. The fire accessory box 304 is installed on the side wall of the second cavity 102 and is electrically connected to both the fire control panel 301 and the fire control box 302. Therefore, when thermal runaway occurs in the battery pack, the fire control panel 301 can quickly spray fire protection medium towards the battery pack to control the spread of thermal runaway. Furthermore, the arrangement of the fire control box 302, fire junction box 303, and fire accessory box 304 helps to improve the simplicity of wiring within the second cavity 102, enhances operational reliability, and reduces the failure rate.
[0035] Optionally, the fire alarm control panel 301 is installed on the rear wall of the second cavity 102, the fire alarm junction box 303 and the fire alarm accessory box 304 are installed on the right side wall of the second cavity 102, and the fire control box 302 is located on the left side wall of the second cavity 102. Installing the fire alarm control panel 301, the fire alarm junction box 303 and the fire alarm accessory box 304, and the fire control box 302 on different side walls of the second cavity 102 helps to improve the space utilization of the second cavity 102 and reduces mutual interference between the various components.
[0036] It should be noted that the fire control panel 301, fire control box 302, fire junction box 303, and fire accessory box 304 can be directly fixed to the side wall of the second cavity 102 by means of screw connection, snap-on connection, etc., or they can be directly fixed to the fixed beam set on the side wall of the second cavity 102 by means of screw connection, snap-on connection, etc. The specific fixing method can be selected according to actual needs.
[0037] Optionally, the fire protection module 300 also includes an alarm 305 installed on the outer wall of the cabinet 100. The alarm 305 can be configured with a buzzer or an alarm light, depending on actual needs. The added alarm 305 can promptly alert the user when the battery pack experiences thermal runaway, preventing larger and more serious accidents.
[0038] Optionally, the power distribution control module 400 includes a molded case circuit breaker 401, an electricity meter 402, an electricity meter fuse 403, a miniature uninterruptible power supply 404, a miniature circuit breaker 405, an intermediate relay 406, a connecting conductor bar 407, a terminal block 408, and an AC surge protection assembly 409.
[0039] Optionally, the cabinet 100 includes a first cabinet 110 and a second cabinet 120. The first cabinet 110 defines a first cavity 101, a second cavity 102, and a third cavity 103. The second cabinet 120 is installed above the first cabinet 110 and defines a fourth cavity. It is understood that the cabinet 100 can be divided into the first cabinet 110 and the second cabinet 120. The second cabinet 120 is used to install the liquid-cooled unit, and the first cabinet 110 is used to install the busbar control module 200, the fire protection module 300, and the power distribution control module 400. The liquid-cooled unit can be directly purchased externally or customized; as a separate component, it facilitates the assembly of the entire energy storage control cabinet.
[0040] Optionally, the first cabinet 110 includes a frame structure 111, a first cabinet door 112, and a second cabinet door 113. The frame structure 111 defines an open first cavity 101, a second cavity 102, and a third cavity 103. The first cabinet door 112 and the second cabinet door 113 are arranged side-by-side on the frame structure 111. The first cabinet door 112 is used to close the first cavity 101, and the second cabinet door 113 closes the second cavity 102 and the third cavity 103. It is understood that in actual operation, the first cabinet door 112 or the second cabinet door 113 can be opened as needed for maintenance and other operations on the bus control module 200, the fire protection module 300, and the power distribution control module 400, facilitating operation by personnel.
[0041] This utility model also discloses an energy storage container, including a container body 700 and an energy storage control cabinet as described above. The container body 700 includes a battery compartment 701 and a control compartment 702. The battery compartment 701 houses multiple battery packs, and the energy storage control cabinet is installed in the control compartment 702.
