[0038] In related technologies, the energy storage cabinet's casing houses a control box and a power distribution box. The power distribution box is electrically connected to both the power grid and the power conversion system to convert AC power from the grid to DC power. The control box is electrically connected to both the power conversion system and the battery clusters to allow direct current to flow to the battery clusters for charging. Both the control box and the power distribution box have corresponding mounting boxes as mounting bases for various electronic components. Both types of mounting boxes require sheet metal fabrication, resulting in a high manufacturing cost for the energy storage cabinet.
[0039] The control box module 200 and the power distribution box module 300 of this application are integrated inside the housing 100, eliminating the need to set up separate mounting boxes for the control box module 200 and the power distribution box module 300, saving the area of sheet metal parts, thereby reducing the manufacturing cost of the energy storage cabinet.
[0040] This application proposes to provide an energy storage system, which includes at least one energy storage cabinet. The energy storage system can be connected to the power grid to enable the flow of electrical energy between the energy storage system and the power grid. Users can store electrical energy from the power grid into battery clusters in the energy storage system, and can also transmit electrical energy from the battery clusters back to the power grid, thereby completing the sale of electricity.
[0041] This application also provides an energy storage cabinet, including a housing, a battery cluster, and a control box device. The battery cluster is disposed within the housing. The battery cluster includes at least one battery pack. The control box device is disposed within the housing, and a housing 100 is mounted on the housing. The control box device is electrically connected to the battery cluster. Exemplarily, the energy storage cabinet also includes a PCS (Power Converter System) for converting alternating current (AC) to direct current (DC). The current in the power grid is AC, and the AC current flows to the PCS through the distribution box module 300, thereby converting it into DC. The DC current then flows to the battery cluster through the control box module 200, thereby charging the battery cluster. On the other hand, the electrical energy of the battery cluster can also flow to the PCS through the control box module 200, thereby converting DC to AC, and then returning to the power grid through the distribution box module 300.
[0042] This application intends to provide a control box device; please refer to [link / reference]. Figure 1 and Figure 2 The control box device includes a housing 100, a control box module 200, and a power distribution box module 300. The housing 100 is generally cubic in shape and includes multiple cavity walls, including side walls, a bottom wall 150, and a top cover 160. The top cover 160 is detachably mounted to the side walls. The top cover 160, side walls, and bottom wall 150 together enclose a mounting cavity 100a. At least a portion of the structures of the control box module 200 and the power distribution box module 300 are located within the mounting cavity 100a. With the top cover 160 open, the operator can install the control box module 200 and the power distribution box module 300 within the mounting cavity 100a and route the wiring.
[0043] The control box module 200 is used to transmit DC power from the power conversion system to the battery cluster for charging. The main functions of the control box module 200 include detection, control, protection circuitry, communication, policy execution, and security management. The control box module 200 is installed inside the housing 100 and is electrically connected to the battery cluster for charging. The control box module includes a first input terminal, a first output terminal, control box devices, and a first wire. The control box devices are electrically connected to the first input terminal and the first output terminal respectively via the first wire.
[0044] The distribution box module 300 is used to transmit AC power from the power grid to the power conversion system. The functions of the distribution box module 300 include power distribution, circuit control, overload and short-circuit protection, power detection, safety isolation and protection, and support for system expansion and maintenance. The control box module includes a second incoming terminal, a second outgoing terminal, distribution box components, and a second conductor. The distribution box module is electrically connected to the second incoming terminal and the second outgoing terminal respectively via the second conductor.
[0045] In the case of removing any one of the cavity walls, the first incoming terminal, the first outgoing terminal, the control box device, the first wire, the second incoming terminal, the second outgoing terminal, the power distribution box device, and the second wire are visible to the outside.
[0046] It should be noted that the electrical connection in the embodiments of this application can be a direct connection or an indirect connection.
[0047] In the embodiment of this application, the control box device includes a control box module 200 and a power distribution box module 300. Both the control box module 200 and the power distribution box module 300 are installed inside the housing 100. Since the control box module 200 and the power distribution box module 300 are integrated into the control box device, there is no need to separately set up mounting boxes for the control box module 200 and the power distribution box module 300, thereby saving the cost of sheet metal parts and reducing the manufacturing cost of the energy storage cabinet. Furthermore, integrating the control box module 200 and the power distribution box module 300 into one unit reduces the space occupied by the control box module 200 and the power distribution box module 300, thus allowing the overall size of the energy storage cabinet to be reduced to a certain extent.
[0048] For example, the housing 100 is provided with heat dissipation holes 100b, which are connected to the outside and the mounting cavity 100a respectively. Heat inside the housing 100 can flow to the outside through the heat dissipation holes 100b, thereby reducing the heat accumulation inside the housing 100.
[0049] In one embodiment, please refer to Figure 1The control box module 200 has a first incoming terminal 200a and a first outgoing terminal 200b, and the distribution box module 300 has a second incoming terminal 300a and a second outgoing terminal 300b. Exemplarily, the first incoming terminal 200a, the first outgoing terminal 200b, the second incoming terminal 300a, and the second outgoing terminal 300b are all mounted on the side wall of the housing 100, and all three terminals penetrate the corresponding side wall so that a portion of the structure is located within the mounting cavity 100a. The second incoming terminal 300a is used for electrical connection with the power grid, the second outgoing terminal 300b is used for electrical connection with the power conversion system, the first incoming terminal 200a is used for electrical connection with the power conversion system, and the first outgoing terminal 200b is used for electrical connection with the battery pack. The control box device also includes a first wire 400 and a second wire 500. The first input terminal 200a and the first output terminal 200b are connected via the first wire 400, and the second input terminal 300a and the second output terminal 300b are electrically connected via the second wire 500. The first wire 400 and the second wire 500 are staggered. It can be understood that staggering the first wire 400 and the second wire 500 means that they do not contact each other, and when projected along the thickness direction of the control box device, the projected areas of the first wire 400 and the second wire 500 do not overlap. The separation of the first wire 400 and the second wire 500 results in a more aesthetically pleasing wiring layout, and reduces the degree of electromagnetic interference between them, thus enhancing the safety and reliability of the control box module 200.
[0050] In one embodiment, please refer to Figure 1 and Figure 3 The second output terminal 300b and the first input terminal 200a are disposed on the same sidewall. For example, the sidewall corresponding to the second output terminal 300b and the first input terminal 200a is the first sidewall 110, the second input terminal 300a and the first output terminal 200b are disposed on the same sidewall, and the sidewall corresponding to the second input terminal 300a and the first output terminal 200b is the second sidewall 120. Both the second output terminal 300b and the first input terminal 200a are used for electrical connection with the power conversion system. The fact that the second output terminal 300b and the first input terminal 200a are located on the same sidewall facilitates connection between the power conversion system and the control box device. The power conversion system can be arranged according to the position of the first sidewall 110, thus eliminating the need for a long extension of the wires to achieve connection between the second output terminal 300b, the first input terminal 200a, and the power conversion system.
[0051] It is understood that other embodiments of this application are not limited to having the second outgoing terminal 300b and the first incoming terminal 200a disposed on the same sidewall. Exemplarily, the second outgoing terminal 300b and the first incoming terminal 200a can be disposed on different sidewalls.
[0052] In one embodiment, please refer to Figure 1 The first sidewall 110 and the second sidewall 120 are arranged opposite to each other. Exemplarily, the first sidewall 110 and the second sidewall 120 extend along a first direction, and are spaced apart along a second direction. The first direction and the second direction are orthogonal, and the first direction is as follows: Figure 1 The direction indicated by the middle arrow R1, the second direction is as follows Figure 1 The direction indicated by the middle arrow R2. The first sidewall 110 and the second sidewall 120 are as far apart as possible, thereby reducing the degree of electromagnetic interference between the terminals.
[0053] It is understood that other embodiments of this application are not limited to the arrangement of the first sidewall 110 and the second sidewall 120 opposite to each other. Exemplarily, the first sidewall 110 and the second sidewall 120 are adjacent, that is, the first sidewall 110 and the second sidewall 120 are connected to each other.
[0054] For example, the sidewall further includes a third sidewall 130 and a fourth sidewall 140, which extend along a second direction and are spaced apart along a first direction. Both the third sidewall 130 and the fourth sidewall 140 are connected to the first sidewall 110 and the second sidewall 120, respectively. The first outgoing terminal 200b and the first incoming terminal 200a are both located on the side of the second outgoing terminal 300b facing the third sidewall 130.
[0055] In one embodiment, please refer to Figure 1 The sidewall corresponding to the second output terminal 300b and the first input terminal 200a is a first sidewall 110, and the first sidewall 110 is made of an insulating material. For example, at least a portion of the structure of the second output terminal 300b and the first input terminal 200a is made of copper. The insulating material of the first sidewall 110 can reduce the possibility of short circuits occurring between the second output terminal 300b and the first input terminal 200a when they are connected together.
[0056] It is understood that other embodiments of this application are not limited to the first sidewall 110 being made of an insulating material. For example, the control box device includes an insulating sleeve that is fitted over the side of the first outgoing terminal 200b and the second incoming terminal 300a, thereby insulating both the second outgoing terminal 300b and the first incoming terminal 200a from the first sidewall 110.
[0057] In one embodiment, please refer to Figure 1 The distribution box device includes a second circuit breaker 310 and a second data acquisition unit 320. The second data acquisition unit 320 is used to acquire the current and / or voltage of the distribution box module 300. The second circuit breaker 310 is configured to disconnect the distribution box module 300. Exemplarily, both the second circuit breaker 310 and the second data acquisition unit 320 are electrically connected to the second outgoing terminal 300b and the second incoming terminal 300a. The second circuit breaker 310, the second data acquisition unit 320, the second incoming terminal 300a, and the second outgoing terminal 300b are connected by a second conductor 500. For example, the control box device also includes a battery management system 700 installed inside the housing 100. The battery management system 700 is electrically connected to the second data acquisition unit 320 and the second circuit breaker 310. The second data acquisition unit 320 can transmit current and voltage data from the power distribution box module 300 to the battery management system 700. The battery management system 700 can analyze the magnitude of the current and voltage, as well as the rate of change of the current and voltage. When the magnitude of the current and voltage exceeds a threshold, or the rate of change of the current and voltage exceeds a threshold, the battery management system 700 can determine that a fault has occurred in the power distribution box system. The battery management system 700 can control the second circuit breaker 310 to disconnect the second wire 500, thereby reducing damage to the power distribution box module 300 and facilitating maintenance personnel to perform repairs. Furthermore, the second circuit breaker 310, the second data acquisition unit 320, and the battery management system 700 are all located inside the housing 100. The surface of the housing 100 does not need to be equipped with power terminals for the second circuit breaker 310 and the second data acquisition unit 320 to achieve electrical connection between the second circuit breaker 310, the second data acquisition unit 320, and the battery relationship system, further reducing the manufacturing cost of the energy storage cabinet.
[0058] For example, please refer to Figure 2 The distribution box module 300 also includes a control component 330, which is partially mounted on the housing 100 and electrically connected to the second circuit breaker 310. The control component 330 has an on-state and an off-state, and the operator can manually switch the control component 330 between these states. When the control component 330 is in the off-state, the first circuit breaker 210 disconnects the circuit in the distribution box module 300; when the control component 330 is in the on-state, the distribution box module 300 is in a closed-circuit state.
[0059] In one embodiment, please refer to Figure 1The control box device includes a first circuit breaker 210 and a first data acquisition unit 220. The first data acquisition unit 220 is used to acquire the current and / or voltage of the control box module 200. The first circuit breaker 210 is configured to disconnect the control box module 200. Exemplarily, the first conductor 400 includes a positive conductor and a negative conductor, the first input terminal 200a includes a first positive terminal and a first negative terminal, and the first output terminal 200b includes a second positive terminal and a second negative terminal. The positive conductor is connected to the first positive terminal and the second positive terminal, and the negative conductor is connected to the first negative terminal and the second negative terminal, respectively. The first circuit breaker 210 and the first data acquisition unit 220 are disposed on the positive conductor, and both the first circuit breaker 210 and the first data acquisition unit 220 are electrically connected to the battery management system 700. The first circuit breaker 210 and the first data acquisition unit 220 can detect the current and voltage in the control box module 200. When the control box module 200 malfunctions, the first circuit breaker 210 can disconnect the path of the control box module 200 to protect the circuit.
[0060] In one embodiment, please refer to Figure 1 The control box module 200 also includes a relay, which is disposed between the first incoming terminal 200a and the first outgoing terminal 200b. The control box module 200 also includes a shunt, which is disposed between the first incoming terminal 200a and the first outgoing terminal 200b, and is used to detect the current in the control box module 200. Exemplarily, both the relay and the shunt are disposed on the negative terminal wire, and both are electrically connected to the battery management system 700. The shunt allows for the measurement of the current in the negative terminal wire, and the relay can disconnect the corresponding circuit in the event of an abnormality in the control box module 200, thereby ensuring the safety of the energy storage cabinet and maintaining stable operation as much as possible.
[0061] In one embodiment, please refer to Figure 1 and Figure 2 The control box device also includes a mounting handle 600, which is mounted to the housing 100 and protrudes along a side opposite to the interior of the housing 100. Exemplarily, there are multiple mounting handles 600, spaced apart along a first direction. The mounting handle 600 may be integrally formed with the housing 100, welded to the housing 100, or bolted to the housing 100. The mounting handle 600 provides load-bearing support for the control box device, allowing operators to move, install, or remove the control box device by holding the mounting handle 600.
[0062] In one embodiment, please refer to Figure 1The control box also includes a UPS (Uninterruptible Power Supply 800), which is electrically connected to the distribution box module 300, and the distribution box module 300 can charge the UPS. The energy storage cabinet also includes a fire-fighting device, which is electrically connected to the UPS so that the UPS can supply power to the fire-fighting device. In the event of an accident involving the energy storage cabinet, the fire-fighting device can spray a flame-retardant medium into the interior of the enclosure, thereby reducing the impact range of the accident.
