Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to an energy storage system. Background Technology

[0002] Most energy storage systems in related technologies use CAN communication (short for Controller Area Network, an ISO internationally standardized serial communication protocol) to allow each node device to send CAN signals to the CAN line (the wire used to transmit CAN signals, usually consisting of two twisted pairs marked CAN-H (high level) and CAN-L (low level), used to transmit differential signals) and achieve signal sharing, thus simplifying wiring setup. However, because energy storage systems integrate multiple CAN signals, it is difficult to quickly locate the communication failure when it occurs. Utility Model Content

[0003] The main purpose of this application is to provide an energy storage system that aims to improve the efficiency of locating and troubleshooting communication faults in the energy storage system.

[0004] To achieve the above objectives, the energy storage system proposed in this application includes:

[0005] Central control cabinet;

[0006] At least two electrical cabinets;

[0007] The first communication connection line includes a first main line and at least three first branch lines, wherein the at least three first branch lines connect the main control cabinet and at least two electrical cabinets in parallel to the first main line; and

[0008] The test structure is located on the first branch line and includes signal test positions.

[0009] The energy storage system in the technical solution of the present application sets a test structure on the first branch line of the first communication connection line and sets a signal test site on the test structure, so that when the energy storage system has a communication failure, the signal test site on the test structure can be used to detect the signal by using a multimeter or other test tools, so as to determine whether the communication signal on the first branch line has a communication failure according to whether the detected test signal is abnormal. In this way, when it is detected that the communication signal on a certain first branch line is normal, it can be quickly determined that the first branch line is normal, and further detection of each node device mounted on the first branch line can be omitted, and detection of the communication signal on the next first branch line can be directly performed until the communication signal is detected to be abnormal. It can be seen that the structure of the energy storage system in the present solution realizes rapid preliminary investigation of the communication failure on each first branch line in the first communication connection line, and the first branch line where the communication failure occurs is located, and accurate investigation can be performed in the smaller range. In this way, the communication failure investigation range can be reduced, thereby facilitating the investigation and positioning efficiency of the communication failure position in the energy storage system.

[0010] Optionally, the first branch line is detachably connected to the first trunk line, and the first branch line in the detached state is defined as a detached branch line.

[0011] The test structure is a test line, and the test line is configured to be detachably connected to the first trunk line and the detached branch line, and the test line is provided with a signal test site.

[0012] In this way, the test structure can be provided as only one set, that is, the test structure can be tested by gradually detaching each first branch line. In this way, the number of test structures is simplified, thereby facilitating the wiring arrangement in the energy storage system.

[0013] Optionally, the test line comprises:

[0014] A connection section, both ends of the connection section are configured to be detachably connected to the first trunk line and the first branch line; and

[0015] A lead-out section, one end of the lead-out section is connected to the connection section, and the other end is provided with a signal test site.

[0016] In this way, the end of the test line is conveniently formed into a connection site for connecting the first trunk line and the first branch line, improving the convenience and stability of the connection of the test line with the first trunk line and the first branch line. At the same time, the end of the test line is also conveniently formed into a signal test site for connecting the test tool, improving the convenience and stability of the connection of the test tool and the test line, and facilitating the accuracy of the test in the stable connection process.

[0017] Optionally, the first main trunk line is provided with a first connector, and the first branch line is provided with a second connector at an end away from the electric cabinet, and the second connector is detachably connected to the first connector.

[0018] The connecting section is provided with a third connector at one end and a fourth connector at the other end.

[0019] The third connector is configured to be detachably connected to the first connector corresponding to the branch line, and the fourth connector is configured to be detachably connected to the second connector on the branch line.

[0020] Thus, the first main trunk line and the first branch line, and the test line and the first main trunk line and the first branch line can be quickly connected by the connectors, thereby facilitating the disassembly and assembly of the first main trunk line and the first branch line, and the test line and the first main trunk line and the first branch line, and further improving the communication troubleshooting positioning efficiency.

[0021] Optionally, the leading section is provided with a test connector at an end away from the connecting section, and the test connector comprises:

[0022] An insulating part, the insulating part is provided with a receiving cavity and a test hole communicating with the receiving cavity, and the test hole is configured as a signal test site; and

[0023] A conductive part, the conductive part is arranged in the receiving cavity and connected to the leading section extending into the receiving cavity.

[0024] Thus, when testing with a test tool, the test pen in the test tool can be inserted into the test hole for testing, so as to stably connect the test tool and the test line and improve the testing accuracy. At the same time, through the insulation effect of the insulating part outside the test connector, even if the two test lines are arranged relatively close to the first main trunk line and the first branch line, electrical burnout will not occur even if contact collision occurs.

[0025] Optionally, the test connector further comprises an elastic member, and the elastic member is configured to clamp the test tool in cooperation with the conductive part when the test tool is inserted into the test hole.

[0026] Thus, the stability of the connection between the test tool and the test line is improved, so as to improve the accuracy of signal testing.

[0027] Optionally, the test connector further comprises an abutting bead connected to the elastic member, and the abutting bead is configured to clamp the test tool in cooperation with the conductive part.

[0028] Thus, when the test tool is inserted into the test hole, the abutting bead is driven to extrude the elastic member to smoothly complete the insertion of the test pen.

[0029] Optionally, the first trunk line comprises a first trunk CAN-H line and a first trunk CAN-L line, and the first branch line comprises a first branch CAN-H line and a first branch CAN-L line;

[0030] The first branch CAN-H line is detachably connected to the first trunk CAN-H line, and the first branch CAN-L line is detachably connected to the first trunk CAN-L line.

[0031] The number of test lines is two, one of which is configured to be detachably connected to the first trunk CAN-H line and the first branch CAN-H line in the detachable branch line, and the other of which is configured to be detachably connected to the first trunk CAN-L line and the first branch CAN-L line in the detachable branch line.

[0032] Thus, the test structure is adapted to the structure of the first branch line, thereby improving the convenience of connecting the test structure and the first branch line.

[0033] Optionally, the two test lines are configured in a twisted pair structure.

[0034] Thus, the structure type of the test structure and the structure type of the first branch line can be similar, thereby facilitating the adaptation of the two and improving the accuracy of restoring the CAN signal on the first branch line, so as to improve the accuracy of subsequent testing.

[0035] Optionally, the energy storage system further comprises at least two second communication connection lines and a plurality of components, and each second communication connection line is arranged in correspondence with an electric cabinet.

[0036] The second communication connection line comprises a second trunk line and at least two second branch lines, the second trunk line is connected to the corresponding electric cabinet, and the at least two second branch lines connect the at least two components in parallel to the second trunk line.

[0037] Thus, the wiring between the electric cabinet and the mounted components can also be simplified, thereby further improving the convenience of wiring the energy storage system and reducing the manufacturing cost. BRIEF DESCRIPTION OF DRAWINGS

[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0050] It should be noted that all directional indications, such as up, down, left, right, front, back, etc., in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0052] In addition, the descriptions involving "first", "second" and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text is to include three parallel schemes, for example, "A and / or B" includes A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0053] The energy storage system (ESS) is a system that can store and supply electric energy, and has functions such as smoothing transition, peak clipping, frequency and voltage regulation. The energy storage system in the related art usually includes a master control cabinet and at least two electric cabinets, and each electric cabinet can also be mounted with at least two parts, such as a water cooling module and a fire-fighting module. Therefore, the structure of the energy storage system in the related art is relatively large. In order to simplify the communication wiring setting of the energy storage system, the CAN bus protocol is used for communication in the energy storage system. The CAN bus protocol is a controller area network bus, which is a serial communication protocol bus for real-time applications, and it can use twisted pair, also known as CAN line, to transmit signals. Specifically, the master control cabinet and at least two electric cabinets are usually connected as node devices in parallel on a CAN line, and each electric cabinet is also provided with another CAN line, so that the mounted parts are connected as node devices in parallel on the CAN line.

[0054] At this time, the CAN line connecting the master control cabinet and the at least two electric cabinets can be defined as the main CAN line, and the CAN line connecting the electric cabinet and the corresponding mounted parts can be defined as the slave CAN line. Whether it is a main CAN line or a slave CAN line, it includes a CAN-H line and a CAN-L line. And when the communication in the energy storage system is normal, the voltage on the CAN-H line is usually 2.5V to 3.5V, and the voltage on the CAN-L line is usually 1.5V to 2.5V. Therefore, the voltage signal on the CAN line can be tested as a test signal to determine whether the communication signal is abnormal, and then the location of the communication fault can be located.

[0055] However, in the related art, when the communication fault position of the energy storage system is investigated and positioned, a universal meter or other voltage testing tool is usually used to detect the entire CAN bus at the test interface of the master control cabinet to investigate each cabinet and each part one by one to determine whether the communication signal is abnormal. At this time, since each cabinet itself forms multiple CAN buses, and the parts mounted on the cabinet further form multiple CAN buses, the number of CAN buses in the energy storage system is large. Therefore, when the energy storage system has a communication fault, it is difficult to quickly investigate and position the CAN communication fault position.

[0056] Therefore, based on the above considerations, in order to solve the problem that it is difficult to investigate and position the communication fault position of the energy storage system in the related art, the present application proposes a new type of energy storage system. The energy storage system innovatively sets a test structure with a signal test site on a first branch line of a first communication connection line for parallel cabinets, so as to realize that each cabinet can be used as a detection unit to quickly and preliminarily investigate the communication signal on each first branch line, until the first branch line where the communication fault is located is positioned, so that accurate investigation can be carried out in this smaller range, thereby improving the investigation and positioning efficiency of the communication fault position in the energy storage system.

[0057] Next, the structure of the energy storage system proposed in the present application will be explained and described in the embodiments:

[0058] Please refer to Figures 1 to 6 In an embodiment of the present application, the energy storage system 100 proposed in the present application includes a master control cabinet 10, at least two cabinets 20, a first communication connection line 30, and a test structure 40; the first communication connection line 30 includes a first main line 31 and at least three first branch lines 33, and the at least three first branch lines 33 parallelly connect the master control cabinet 10 and the at least two cabinets 20 to the first main line 31; the test structure 40 is arranged on the first branch line 33, and the test structure 40 is provided with a signal test site 4134.

[0059] The master control cabinet 10 can be used to control each cabinet 20 to be responsible for data acquisition, network monitoring, energy scheduling, etc. of each cabinet 20. The master control cabinet 10 can include a master controller to be connected with the corresponding first branch line 33.

[0060] The cabinet 20 can be used to store electrical energy and release it for power use when needed. The cabinet 20 can include a controller to be connected with the corresponding second branch line 73. In addition, the number of cabinets 20 can be two, three or more, and the present application does not limit the number of cabinets 20.

[0061] The first communication connection line 30 can be used to connect the master control cabinet 10 and the electric cabinet 20 to establish the communication connection between the master control cabinet 10 and each electric cabinet 20. The first main line 31 in the first communication connection line 30 can be arranged along the arrangement direction of each first branch line 33, and one end of each first branch line 33 can be connected to the first main line 31, and the other end can be connected to the corresponding master control cabinet 10 or electric cabinet 20. Further, the first communication connection line 30 can be a CAN line with a double-wire structure as described above to simplify the communication wiring arrangement of the energy storage system 100. At this time, the first main line 31 can include a first main CAN-H line 311 and a first main CAN-L line 313, the first branch line 33 can include a first branch CAN-H line 331 and a first branch CAN-L line 333, the first branch CAN-H line 331 is connected to the first main CAN-H line 311, and the first branch CAN-L line 333 is connected to the first main CAN-L line 313. Moreover, in order to reduce signal reflection and improve signal quality, the first main CAN-H line 311 and the first main CAN-L line 313 are both provided with a 120-ohm terminal resistor between the ends. At this time, the first main CAN-H line 311 and the first main CAN-L line 313 can form a closed loop. Of course, in other embodiments, the first communication connection line 30 can also be a single-wire structure, and the type of the first communication connection line 30 is not limited in the present application.

[0062] The test structure 40 can be connected with the first branch line 33 and lead out a signal test site 4134 to be connected with the test tool 300 such as a multimeter or a voltmeter for voltage measurement when troubleshooting communication failure. The test structure 40 can be a test line 41 as described below, or can be a contact terminal or a connector. It is to be understood that the structure type of the test structure 40 is not limited in the present application. When the first communication connection line 30 is a CAN line in a double wire structure as described above, the test structure 40 can be distributed on the first branch CAN-H line 331 and the first branch CAN-L line 333 to correspond to the structure of the first branch line 33. In addition, the test structure 40 can be arranged at one end of the first branch line 33 close to the first trunk line 31, or can be arranged at one end of the first branch line 33 close to the electric cabinet 20, or can be arranged at the middle position of the first branch line 33. It is to be understood that the arrangement position of the test structure 40 is not limited in the present application. In addition, the test structure 40 can be arranged in a group and can be detachably arranged as described below, so that it can be gradually installed on each first branch line 33 for testing. That is, after testing a group of first branch lines 33, the test structure 40 can be detached and installed on the next group of first branch lines 33 for testing. Of course, the present application is not limited to this, and the test structure 40 can be arranged in at least two groups to be respectively installed on each group of first branch lines 33. At this time, the test structure 40 can be arranged in a fixed manner. The detachable connection defined in the present application means that after the two are assembled and connected, they can still be separated. The fixed connection means that the two are directly integrated, or after assembly and connection, they cannot be separated. In addition, the signal test site 4134 on the test structure 40 can be used for contact testing by the test tool 300 such as a multimeter or a voltmeter. The signal test site 4134 can be a hole body of a test hole 4135 as described below. Of course, it can also be in the form of a flat surface or an arc surface, and the structure form of the signal test site 4134 is not limited in the present application.

[0063] The energy storage system 100 in the technical solution of the present application sets the test structure 40 on the first branch line 33 of the first communication connection line 30 and sets the signal test site 4134 on the test structure 40, so that when the energy storage system 100 has a communication fault, the signal test site 4134 on the test structure 40 can be used to detect the signal by using a test tool 300 such as a multimeter, so as to determine whether the communication signal on the first branch line 33 has a communication fault according to whether the detected test signal (for example, the voltage signal detected by the multimeter or the voltmeter) is abnormal. In this way, when it is detected that the communication signal on a certain first branch line 33 is normal, it can be quickly determined that the first branch line 33 is normal, and further detection of each node device mounted on the first branch line 33 can be omitted, and the detection of the communication signal on the next first branch line 33 can be directly performed until the abnormal communication signal is detected. It can be seen that the structure of the energy storage system 100 in the present solution realizes rapid preliminary investigation of the communication fault on each first branch line 33 in the first communication connection line 30, and the first branch line 33 where the communication fault is located is located, and accurate investigation can be performed in the smaller range. In this way, the communication fault investigation range can be reduced, thereby facilitating the investigation and positioning efficiency of the communication fault position in the energy storage system 100.

[0064] For reference Figures 2 to 6 In an embodiment of the present application, the first branch line 33 is detachably connected to the first trunk line 31, and the first branch line 33 in the detached state is defined as a detached branch line; the test structure 40 is a test line 41, and the test line 41 is configured to be detachably connected to the first trunk line 31 and the detached branch line, and the test line 41 is provided with the signal test site 4134.

[0065] The first branch line 33 is detachably connected to the first trunk line 31, that is, after being connected to the first trunk line 31, the first branch line 33 can still be separated from the first trunk line 31. The first branch line 33 and the first trunk line 31 can be detachably connected by a connector as described below. Of course, the metal wire inside the first branch line 33 can be directly wound on the first trunk line 31. It can be seen that the detachable connection mode of the first branch line 33 and the first trunk line 31 is not limited in the present application. The test structure 40 is a test line 41, that is, a wire structure. The test structure 40 is detachably connected to the first trunk line 31 and the detached branch line. That is, a set of test structures 40 are provided, and only when a certain first branch line 33 needs to be tested for failure, it is installed on the first branch line 33. When the first communication connection line 30 is a CAN line as described above, the first branch line 33 includes a first branch CAN-H line 331 and a first branch CAN-L line 333. Therefore, two test lines 41 can be included in a set of test structures 40 to connect to the first branch CAN-H line 331 and the first branch CAN-L line 333, respectively. In addition, the test line 41 and the first branch line 33 can be detachably connected by a connector as described below. Of course, the metal wire inside the test line 41 can be directly wound on the first branch line 33.

[0066] In the present embodiment, the first branch line 33 and the first trunk line 31 are detachable, so that the test structure 40 can be provided as a set, that is, the test structure 40 can be installed and tested by gradually detaching each first branch line 33. In this way, the number of test structures 40 is simplified, which is conducive to simplifying the wiring arrangement in the energy storage system 100. Further, the test structure 40 is provided as a test line 41, which can correspond to the structure of the second branch line 73, that is, both are wire structures, which is conducive to improving the adaptability of the two and improving the convenience of connection.

[0067] Please refer to Figures 2 to 6 In an embodiment of the present application, the test line 41 includes a connection section 411 and a lead-out section 413. The two ends of the connection section 411 are detachably connected to the first trunk line 31 and the first branch line 33, respectively. One end of the lead-out section 413 is connected to the connection section 411, and the other end is provided with a signal test site 4134.

[0068] The connecting segment 411 can be used to provide a connecting site for connecting with the first main line 31 and the first branch line 33 respectively. The leading-out segment 413 can be used to lead out the signal test site 4134 from the connecting segment 411. At this time, the leading-out segment 413 and the connecting segment 411 can form a "T" shape. The two test lines 41 in the test structure 40 can be arranged to include the connecting segment 411 and the leading-out segment 413, i.e., the two test lines 41 are arranged to be consistent.

[0069] In the embodiment, the test line 41 is arranged to include the connecting segment 411 and the leading-out segment 413, so that the end of the test line 41 can conveniently form the connecting site for connecting with the first main line 31 and the first branch line 33, thereby facilitating the convenience and stability of the connection between the test line 41 and the first main line 31 and the first branch line 33. Meanwhile, the end of the test line 41 can conveniently form the signal test site 4134 for connecting with the test tool 300, thereby facilitating the convenience and stability of the connection between the test tool 300 and the test line 41, and improving the accuracy of the test in the stable connection process.

[0070] For reference Figures 2 to 4 In an embodiment of the present application, the first main line 31 is provided with a first connector 315, and the first branch line 33 is provided with a second connector 335 at an end away from the cabinet 20, the second connector 335 being detachably connected to the first connector 315. One end of the connecting segment 411 is provided with a third connector 4111, and the other end is provided with a fourth connector 4113. The third connector 4111 is configured to be detachably connected to the first connector 315 corresponding to the branch line to be disconnected, and the fourth connector 4113 is configured to be detachably connected to the second connector 335 on the branch line to be disconnected.

[0071] The first connector 315 can be a three-way connector. That is, the first connector 315 can have three connection points, which can be defined as a first connection point, a second connection point and a third connection point respectively. At this time, the first trunk line 31 can be provided to include a plurality of segment bodies (when the first communication connection line 30 is a CAN line with a double-line structure as described above, the first trunk CAN-H line 311 and the first trunk CAN-L line 313 can each be provided to include a plurality of segment bodies), and two adjacent segment bodies can be directly connected to the first connection point and the second connection point in the first connector 315 respectively. Of course, the two adjacent segment bodies can also be provided with a single-way connector to be connected to the first connection point and the second connection point in the first connector 315 respectively. The second connector 335 can be a single-way connector, that is, it has one connection point, which can be defined as a fourth connection point. The fourth connection point can be used to connect to the third connection point in the first connector 315. The third connector 4111 can be a single-way connector, that is, it has one connection point, which can be defined as a fifth connection point. The fifth connection point can be used to connect to the third connection point in the first connector 315. The fourth connector 4113 can be a single-way connector, that is, it has one connection point, which can be defined as a sixth connection point. The sixth connection point can be used to connect to the fourth connection point in the second connector 335. Therefore, when the first connector 315 is a female end and the second connector 335 is a male end that is plugged into the first connector 315, the third connector 4111 can also be provided as a male end like the second connector 335 to be plugged into the first connector 315. The fourth connector 4113 can be provided as a female end to be plugged into the second connector 335.

[0072] In the present embodiment, by providing the first connector 315 on the first trunk line 31, the second connector 335 on the first branch line 33, and the third connector 4111 and the fourth connector 4113 on the test line 41, the first trunk line 31 and the first branch line 33, and the test line 41 and the first trunk line 31 and the first branch line 33 can all be quickly connected by connectors. This facilitates the disassembly and assembly of the first trunk line 31 and the first branch line 33, and the test line 41 and the first trunk line 31 and the first branch line 33, and further improves the efficiency of communication fault locating.

[0073] For reference Figures 4 to 6In an embodiment of the present application, the test joint 4131 is arranged at one end of the connecting segment 411 away from the lead-out segment 413, and includes an insulating part 4132 and a conductive part 4136. The insulating part 4132 is provided with a receiving cavity 4133 and a test hole 4135 communicating with the receiving cavity 4133, and the test hole 4135 is configured as a signal test site 4134. The conductive part 4136 is arranged in the receiving cavity 4133 and connected with the lead-out segment 413 extending into the receiving cavity 4133.

[0074] The test joint 4131 can be mechanically connected with the lead-out segment 413 through the insulating part 4132, and electrically connected with the lead-out segment 413 through the conductive part 4136. The conductive part 4136 can be made of metal capable of conducting electricity, such as copper or aluminum.

[0075] In the embodiment, the test joint 4131 is arranged at the end of the lead-out segment 413, and the test hole 4135 is arranged on the test joint 4131.
