It is noted that like numbers and letters refer to like elements throughout the several views of the drawings, and that the use of or reference to certain terms in various places of the specification are not intended to exclude those terms from the scope of the application, but rather to clarify the description of the application.

[0053] In order to solve the problems of low space utilization and poor heat dissipation of the energy storage box, according to the embodiments of the present application, an energy storage integrated box is provided. The energy storage integrated box of the present application will be described in detail below in combination with the drawings.

[0054] Referring to Figures 1 to 13 As shown in the drawings, according to the embodiments of the present application, an energy storage integrated box is provided, which is used for connecting between a battery cluster 1 and a power supply 2. The energy storage integrated box comprises a box body 10, a PCS box 20, a high-voltage box 30, an industrial computer 40, and a circuit assembly 50.

[0055] The box body 10 is provided with a cavity 11, and the side surface of the box body 10 is provided with a first end plate 12 and a second end plate 13 opposite to the first end plate 12. The cavity 11 is provided with a frame 14. The PCS box 20 is arranged in the cavity 11 and is used for electrically connecting with the power supply 2. The PCS box 20 is fixed to the frame 14 and at least partially protrudes from the second end plate 13. The high-voltage box 30 is located in the cavity 11 and is electrically connected between the PCS box 20 and the battery cluster 1. The high-voltage box 30 is fixed to the frame 14 and the first end plate 12. The industrial computer 40 is arranged in the cavity 11 and is electrically connected with the PCS box 20 and the high-voltage box 30. The circuit assembly 50 comprises a high-voltage circuit 51 and a branch circuit 52. The high-voltage circuit 51 is laid on the bottom of the box body 10 and is used for electrically connecting between the power supply 2 and the PCS box 20. The branch circuit 52 is laid on the end away from the high-voltage circuit 51. The PCS box 20 and the high-voltage box 30 are electrically connected to the industrial computer 40 through the branch circuit 52.

[0056] In the present application, the energy storage integrated box can integrate the PCS box 20, the high-voltage box 30 and the industrial computer 40 in the cavity 11, and can set the frame 14 that can support the PCS box 20, the high-voltage box 30 and the industrial computer 40 in the cavity 11, so that the box 10 can share the gravity from the PCS box 20, the high-voltage box 30 and the industrial computer 40, so that the box 10 is not easy to be deformed under the action of gravity. Moreover, the setting of the frame 14 can also make the layout of the PCS box 20, the high-voltage box 30 and the industrial computer 40 in the cavity 11 more reasonable and compact, so as to improve the space utilization of the energy storage integrated box. In actual work, the energy storage integrated box can convert alternating current from the power supply 2 into direct current and store it in the battery cluster 1, and can also convert the direct current stored in the battery cluster 1 into alternating current to provide for users to use. Since the PCS box 20 of the present application at least partially protrudes from the second end plate 13 (i.e. protrudes from the external space of the cavity 11), the heat generated by the PCS box 20 during operation can be dispersed to the external space of the cavity 11 in time, so as to improve the heat dissipation effect of the energy storage integrated box. In addition, since the high-voltage line 51 of the present application is laid on the bottom of the box 10 and the branch line 52 is laid on the end away from the high-voltage line 51, such arrangement can reduce the influence of the high-voltage line 51 on the branch line 52, so that the energy storage integrated box of the present application can be better applied to the conversion between alternating current and direct current.

[0057] That is to say, compared with the existing energy storage integrated box, the energy storage integrated box of the present application can integrate the PCS box 20, the high-voltage box 30 and the industrial computer 40 into the cavity 11 through simple structural design, and can also improve the space utilization and heat dissipation effect of the energy storage integrated box, so that the energy storage integrated box of the present application has better performance.

[0058] Further, as shown in Figure 8 , Figure 9 and Figure 12 , the PCS box 20 and the first end plate 12 have a first gap w, and the high-voltage box 30 and the second end plate 13 have a second gap m.

[0059] Specifically, the PCS box 20 can realize conversion from AC to DC, and also can realize conversion from DC to AC. When the energy storage integrated box is in the charging mode, the PCS box 20 can convert AC power from the power supply 2 into DC power and transmit the DC power to the battery cluster 1 for storage. When the energy storage integrated box is in the discharging mode, the PCS box 20 can convert the DC power stored in the battery cluster 1 into AC power and transmit the AC power to the user for use. Moreover, the PCS box 20 also has the functions of power quality control, energy management, fault isolation, coordinated control, communication and monitoring, etc. Therefore, the PCS box 20 will generate a large amount of heat during work. The first gap w and the second gap m can make the heat generated by the PCS box 20 during work be transmitted to the air in time, thereby playing a role in cooling the PCS box 20 to a certain extent, so as to prevent the PCS box 20 from not working normally due to high temperature. In addition, since the first gap w is close to the first end plate 12 and the second gap m is close to the second end plate 13, the air can flow better in the cavity 11, thereby taking away the heat generated by the energy storage integrated box during work, improving the heat dissipation effect of the energy storage integrated box.

[0060] Further, as shown in Figure 1 、 Figure 3 and Figures 9 to 10 , the box body 10 includes a first mesh opening 101, which is arranged at the first end plate 12 close to the first gap w and is in communication with the first gap w. Specifically, the first mesh opening 101 is opposite to one end of the PCS box 20 close to the first gap w. Since the first mesh opening 101 is in communication with the first gap w, the air outside the box body 10 can enter the inside of the box body 10 (i.e. enter the cavity 11) through the first mesh opening 101, and the air in the cavity 11 can also be discharged to the outside of the box body 10 through the first mesh opening 101. In this way, the heat generated by the energy storage integrated box during work can be discharged to the outside of the box body 10. Moreover, compared with the hot air inside the box body 10, the cold air outside the box body 10 can further cool the electrical components inside the box body 10 after entering the cavity 11 through the first mesh opening 101.

[0061] Optionally, as shown in Figure 9 and Figure 11As shown in FIG. 1, the PCS box 20 comprises a second air port 201 located at one end of the PCS box 20 close to the first gap w. Specifically, the second air port 201 is located opposite to the first air port 101. In this way, the heat generated by the PCS box 20 during operation can be discharged to the first gap w through the second air port 201, and then discharged to the outside space of the cabinet 10 through the first air port 101, so as to cool the energy storage integrated cabinet. In addition, compared with the hot air inside the cabinet 10, the cold air outside the cabinet 10 can enter the first gap w through the first air port 101, and then enter the inside of the PCS box 20 through the second air port 201, so as to cool the PCS box 20.

[0062] Optionally, as shown in FIG. 1, Figure 2 、 Figure 4 and Figure 10 As shown in FIG. 1, the PCS box 20 further comprises a third air port 202 located at one end of the PCS box 20 protruding from the second end plate 13. Specifically, the heat generated by the PCS box 20 during operation can be directly discharged to the outside space of the cabinet 10 through the third air port 202, so as to cool the PCS box 20. At the same time, compared with the hot air inside the PCS box 20, the cold air outside the cabinet 10 can directly enter the inside of the PCS box 20 through the third air port 202, so as to cool the PCS box 20.

[0063] In addition, when the first air port 101, the second air port 201 and the third air port 202 are provided at the same time, a relatively complete air circulation channel can be provided for the energy storage integrated cabinet of the present application. The hot air inside the cabinet 10 can be discharged to the outside space of the cabinet 10 through the first air port 101, the second air port 201 and the third air port 202. At the same time, the cold air outside the cabinet 10 can also enter the inside of the cabinet 10 through the first air port 101, the second air port 201 and the third air port 202, so as to cool the inside of the energy storage integrated cabinet. Compared with the existing energy storage integrated cabinet, the energy storage integrated cabinet of the present application has better heat dissipation effect.

[0064] Further, as shown in FIG. 1, Figure 9 The first wiring terminal 203 is arranged on the PCS box 20, and the second wiring terminal 301 is arranged on the high-voltage box 30. Wherein, along the first direction of the cabinet 10, the PCS box 20 and the high-voltage box 30 are arranged in the cavity 11 with a spacing, the first wiring terminal 203 is located at one side of the PCS box 20 close to the high-voltage box 30, the second wiring terminal 301 is located at one side of the high-voltage box 30 close to the PCS box 20, and the first wiring terminal 203 and the second wiring terminal 301 are electrically connected through the branch circuit 52.

[0065] Specifically, the first direction is Figure 9the direction of x. In the present application, since the first terminal 203 is located at the side of the PCS box 20 close to the high-voltage box 30, and the second terminal 301 is located at the side of the high-voltage box 30 close to the PCS box 20. Therefore, when the branch circuit 52 is used to electrically connect the first terminal 203 and the second terminal 301, the branch circuit 52 required can be shorter, so as to reduce the layout of the branch circuit 52 to a certain extent, that is, to simplify the assembly steps of the energy storage integrated box, and to save costs. In addition, since the PCS box 20 and the high-voltage box 30 are spaced apart in the direction of x (i.e. the first direction) in the cavity 11, when the energy storage integrated box is working, the air inside the energy storage integrated box flows more conveniently, and the heat inside the box 10 can be more easily discharged from the first mesh opening 101 and the third mesh opening 202 to the outside space of the box 10, so as to achieve heat dissipation of the energy storage integrated box. At the same time, the air outside the box 10 can also more easily enter the cavity 11 through the first mesh opening 101 and the third mesh opening 202 and circulate in the cavity 11, which can further dissipate heat for the energy storage integrated box.

[0066] Further, referring to Figures 8 to 13 As shown, the second gap m is provided with the industrial computer 40 and the support plate 15. Among them, the industrial computer 40 is close to the top of the box 10 and the PCS box 20, and the industrial computer 40 is fixed to the second end plate 13 and the frame 14. Along the first direction of the box 10, the support plate 15 is spaced apart from the industrial computer 40 in the second gap m, and the support plate 15 is located away from the PCS box 20 and is fixed to the second end plate 13 and the frame 14, and the support plate 15 is at least used to place the industrial computer host 200.

[0067] Specifically, the industrial computer 40 can collect data from various electrical components inside the energy storage integrated box, and optimize the performance of the energy storage integrated box through an algorithm, that is, the industrial computer 40 can communicate with electrical components such as the PCS box 20 and the high-voltage box 30, collect data from electrical components such as the PCS box 20 and the high-voltage box 30 and make decisions, so as to achieve the purpose of controlling electrical components such as the PCS box 20 and the high-voltage box 30. In addition, as Figure 9As shown, the industrial computer 40 can also be connected with and communicate with the liquid cooling unit and the touch screen outside the energy storage integrated box. The liquid cooling unit can better dissipate heat for the energy storage integrated box, and the data of each electrical component in the energy storage integrated box can be transmitted to the touch screen for display. The operator can give instructions to the industrial computer 40 through the touch screen, so as to better control the energy storage integrated box to work. Moreover, compared with the existing energy storage integrated box, the energy storage integrated box of the present application is provided with a support plate 15 on which the industrial computer host 200 can be placed in the cavity 11 of the box body 10, and the position of the support plate 15 is reasonably arranged, so that the space utilization of the cavity 11 is higher. Generally, the industrial computer host 200 does not need to be installed in the energy storage integrated box. When the energy storage integrated box needs to be connected with multiple energy storage integrated boxes or other commercial energy storage cabinets, the industrial computer host 200 can be installed at the support plate 15. Compared with the existing way of arranging the industrial computer host 200 outside the energy storage integrated box, the energy storage integrated box of the present application is more beautiful and saves space.

[0068] Further, referring to Figure 7 、 Figures 10 to 12 As shown, the energy storage integrated box further comprises an isolation transformer 60, and a third gap u is arranged between the high-voltage box 30 and the bottom of the box body 10. The first end of the isolation transformer 60 is electrically connected with the power supply 2, the second end of the isolation transformer 60 is electrically connected with the industrial computer 40, and the isolation transformer 60 is located in the third gap u and fixed to the bottom of the box body 10.

[0069] Specifically, the isolation transformer 60 has the functions of electrical isolation, safety protection, improvement of power quality, voltage transformation and the like. The industrial computer 40, the touch screen and the control circuit and the like are electrically isolated through the isolation transformer 60, which can avoid the influence of high-voltage electricity on the industrial computer 40, the touch screen and the control circuit and the like during work, can better protect the electrical components in the energy storage integrated box, and improve the service life of the energy storage integrated box. At the same time, the arrangement of the isolation transformer 60 also increases the safety of the energy storage integrated box of the present application. In the present application, the high-voltage box 30 is fixed to the frame 14 in the box body 10. Since the third gap u is arranged between the high-voltage box 30 and the bottom of the box body 10, the isolation transformer 60 and other electrical components can be placed in the third gap u, thereby improving the utilization rate of the cavity 11 in the box body 10. In addition, the branch line 52 for communication between electrical components can be arranged in the third gap u away from the bottom of the box body 10, which can make the wiring in the energy storage integrated box more reasonable, and also can reduce the influence of the high-voltage line 51 on the branch line 52.

[0070] Further, referring to Figure 7 、 Figures 10 to 12As shown, the energy storage integrated box further comprises a first circuit breaker 70a, a second circuit breaker 70b and a surge protector 80. The first circuit breaker 70a is electrically connected to the PCS box 20 at one end, and is electrically connected to the power supply 2 at the other end. The second circuit breaker 70b is electrically connected to the first end of the isolation transformer 60 of the energy storage integrated box at one end, and is electrically connected to the power supply 2 at the other end. The surge protector 80 is arranged in the cavity 11, and one end of the surge protector 80 is electrically connected to the power supply 2, and the other end of the surge protector 80 is grounded.

[0071] Specifically, the first circuit breaker 70a can provide protection for the PCS box 20, the high-voltage box 30 connected to the PCS box 20 and the battery cluster 1, preventing the PCS box 20, the high-voltage box 30 and the battery cluster 1 from being damaged in the case of overload or short circuit. Correspondingly, the second circuit breaker 70b can provide protection for the isolation transformer 60 and the electrical appliances and lines connected to the isolation transformer 60, preventing the isolation transformer 60 and the electrical appliances and lines connected to the isolation transformer 60 from being damaged in the case of overload or short circuit. The surge protector 80 can prevent damage to sensitive electronic devices in the energy storage integrated box caused by voltage transients (surges) due to lightning strikes, power grid switching, equipment starting, etc. Moreover, the surge protector 80 has the advantages of voltage clamping, current discharge and ensuring system stability, and can prolong the service life of the energy storage integrated box of the present application and improve the safety of the energy storage integrated box of the present application.

[0072] Further, as shown in Figure 3 , Figure 7 and Figures 10 to 12 , the first circuit breaker 70a comprises a molded case circuit breaker 701, which is located in the third gap u of the cavity 11 and fixed to the bottom of the box body 10, and the molded case circuit breaker 701 has an operating handle 7011 which protrudes from the first end plate 12 and can be rotated in a predetermined direction.

[0073] Specifically, the molded case circuit breaker 701 has the advantages of isolation function, easy reset and adaptation to various environments, and can be used as a manual switch for opening or closing the circuit, providing a safe operating point when maintenance or repair is required. If the operating handle 7011 is rotated in the clockwise direction (i.e. the direction indicated by arrow a in Figure 3 , the molded case circuit breaker 701 is opened, and if the operating handle 7011 is rotated in the counterclockwise direction (i.e. the direction indicated by arrow b in Figure 3The operating handle 7011 (in the direction indicated by b) is rotated to close the molded case circuit breaker 701. When maintenance is required on electrical components connected to the molded case circuit breaker 701, the operating handle 7011 can be rotated clockwise to open the molded case circuit breaker 701. After maintenance is completed, the operating handle 7011 can be rotated counterclockwise to close the molded case circuit breaker 701, at which point the electrical components connected to the molded case circuit breaker 701 can continue to operate. Compared to traditional fuses, the molded case circuit breaker 701 can be manually reset to reconnect the circuit after tripping, reducing the hassle of replacing components and making the energy storage integrated box of this application more convenient to use.

[0074] Further, see Figure 12 and Figure 13 As shown, the high-voltage box 30 also includes a battery cell management unit 302. One end of the battery cell management unit 302 is electrically connected to the second end of the isolation transformer 60 of the energy storage integrated box, and the other end of the battery cell management unit 302 is used to be electrically connected to the battery cluster 1.

[0075] Specifically, the battery cell management unit 302 has functions such as voltage monitoring, temperature monitoring, balance control, fault detection, and data communication. In this application, the battery cell management unit 302 can monitor and manage individual battery cells in the battery cluster 1, enabling the energy storage integrated box to better protect the battery cluster 1 during operation, thereby improving the service life of the battery cluster 1 and the safety of the energy storage integrated box. Furthermore, since the battery cell management unit 302 and the power source 2 are separated by an isolation transformer 60, the high-voltage electricity from the power source 2 is isolated from the battery cell management unit 302, thus ensuring the normal operation of the battery cell management unit 302.

[0076] Further, see Figure 12 As shown, the integrated energy storage box also includes a first fuse 90a, a second fuse 90b, a third fuse 90c, a fourth fuse 90d, a fifth fuse 90e, and a sixth fuse 90f. The first fuse 90a, second fuse 90b, third fuse 90c, and fourth fuse 90d are respectively connected between the power supply 2 and the surge protector 80 of the integrated energy storage box. One end of the fifth fuse 90e is electrically connected to the isolation transformer 60 of the integrated energy storage box, and the other end is electrically connected to the industrial control computer 40. One end of the sixth fuse 90f is electrically connected to the second end of the isolation transformer 60 of the integrated energy storage box, and the other end is electrically connected to the battery cell management unit 302 of the high-voltage box 30.

[0077] Specifically, the first fuse 90a, the second fuse 90b, the third fuse 90c, the fourth fuse 90d, the fifth fuse 90e and the sixth fuse 90f have the functions of overload protection and short-circuit protection. When the current in the circuit exceeds the rated value of the fuse, the fuse wire (usually lead, tin or copper alloy) inside the fuse will melt due to overheating in a short time, thereby breaking the circuit and preventing the equipment from being damaged due to overload. Not only that, when a short circuit occurs in the circuit, the current will increase sharply, and the fuse will melt quickly to cut off the power supply, avoiding greater losses or fire risks caused by short circuits. In addition, the first fuse 90a, the second fuse 90b, the third fuse 90c, the fourth fuse 90d, the fifth fuse 90e and the sixth fuse 90f also have the advantages of simplicity and economy. Compared with other types of protection devices, the fuse has a simple structure, low cost, and is easy to install and maintain, so it can reduce the cost of the energy storage integrated box of the present application.

[0078] Further, referring to Figure 13 As shown, the energy storage integrated box also includes a safety assembly 100, which is arranged in the cavity and electrically connected with the industrial computer 40. The safety assembly 100 includes an emergency stop switch 1001, an access control switch 1002, a water immersion controller 1003, a lightning protection device 1004, a smoke detector 1005, a fire extinguishing device 1006 and a temperature sensor 1007, and the emergency stop switch 1001, the access control switch 1002, the water immersion controller 1003, the lightning protection device 1004, the smoke detector 1005, the fire extinguishing device 1006 and the temperature sensor 1007 are respectively arranged in the cavity 11 and electrically connected with the industrial computer 40.

[0079] Specifically, the electrical connection between the safety assembly 100 and the industrial computer 40 adopts a dry contact connection, which can be used for signal transmission. The emergency stop switch 1001, the access control switch 1002, the water immersion controller 1003, the lightning protection device 1004, the smoke detector 1005, the fire extinguishing device 1006 and the temperature sensor 1007 can cooperate with the industrial computer 40, thereby providing a relatively complete safety system for the energy storage integrated box of the present application. When the corresponding situation occurs, the corresponding electrical component in the safety assembly 100 will be triggered, and then a signal will be sent to the industrial computer 40. The industrial computer 40 can identify the corresponding signal to control the electrical components in the energy storage integrated box or prompt the operator to take appropriate measures. Thus, the occurrence of danger is prevented.

[0080] Further, referring to Figures 1 to 4 , Figure 6 , Figure 7 and Figure 11As shown, the box body 10 further has a first mounting portion 102 and a second mounting portion 103. The first mounting portion 102 is arranged in the first gap w of the box body 10 and fixedly connected to the first end plate 12, and at least one of the emergency stop switch 1001, the access control switch 1002, the water immersion controller 1003, the lightning protection device 1004, the smoke detector 1005, the fire extinguishing device 1006 and the temperature sensor 1007 is arranged in the first mounting portion 102. The second mounting portion 103 is arranged in the second gap m of the box body 10 and fixedly connected to the second end plate 13, and at least one of the emergency stop switch 1001, the access control switch 1002, the water immersion controller 1003, the lightning protection device 1004, the smoke detector 1005, the fire extinguishing device 1006 and the temperature sensor 1007 is arranged in the second mounting portion 103.

[0081] Specifically, in the present application, the arrangement of the first mounting portion 102 and the second mounting portion 103 enables the energy storage integrated box to centrally install the emergency stop switch 1001, the access control switch 1002, the water immersion controller 1003, the lightning protection device 1004, the smoke detector 1005, the fire extinguishing device 1006 and the temperature sensor 1007 together. Since the emergency stop switch 1001, the access control switch 1002, the water immersion controller 1003, the lightning protection device 1004, the smoke detector 1005, the fire extinguishing device 1006 and the temperature sensor 1007 are vulnerable parts, the centralized installation of the safety components 100 in the corresponding positions of the energy storage integrated box can facilitate the maintenance personnel to replace the safety components 100 after they are damaged, thereby improving the maintenance efficiency.

[0082] It can be known from the above description that the energy storage integrated box of the present application can integrate the PCS box 20, the high-voltage box 30, the industrial computer 40, the line assembly 50 and the isolation transformer 60 and other electrical components into the cavity 11 inside the box body 10, thereby solving the problems of low space utilization and poor heat dissipation effect of the energy storage box. In the present application, the high-voltage box 30 and the PCS box 20 are wired and electrically connected to each other on the side close to each other, which can reduce the use of the branch line 52 and save costs. At the same time, the layout of the PCS box 20 and the high-voltage box 30 inside the box body 10 is reasonably arranged, facilitating the circulation of air inside the box body 10. Moreover, the end of the PCS box close to the second end plate 13 partially protrudes outside the box body 10, increasing the heat dissipation area of the PCS box, and the first network port 101, the second network port 201 and the third network port 202 are further arranged on the energy storage integrated box, which can greatly improve the heat dissipation effect of the energy storage integrated box. In addition, the energy storage integrated box of the present application separately arranges the high-voltage line 51 and the branch line 52, which can reduce the influence of the high-voltage line 51 on the branch line 52 and avoid affecting the normal work of the energy storage integrated box.

[0083] That is to say, the application can integrate multiple electrical components together through simple structural design, improve space utilization, centralize vulnerable components, facilitate maintenance, and improve maintenance efficiency and reduce costs to a certain extent.
