[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the existing related technologies, the battery energy storage container has safety risks in each product stage before it is officially put into use, such as production assembly, transportation, and on-site installation and commissioning. For example, collision or tipping during the transportation stage or the hoisting process at the work site can cause battery short circuits and fires. The wiring process during the production assembly and installation and commissioning stages can also cause battery short circuits and thermal runaway risks. Since the safety and fire monitoring systems of the battery energy storage container itself are not powered on and enabled during the product stages before the battery energy storage container is officially put into use, all product stages before it is officially put into use are currently monitored manually. Manual monitoring cannot detect the above risk issues in a timely manner and alarm, thereby delaying the opportunity to deal with the risks and causing safety accidents.

[0026] In view of the above problems existing in the existing related technologies, an embodiment of the present invention provides a battery energy storage container monitoring system, which is used for risk monitoring of various product stages of the battery energy storage container before it is officially put into use. Figure 1 is a schematic diagram of the structure of the battery energy storage container monitoring system provided in this embodiment. Figure 1 As shown, the battery energy storage container monitoring system of this embodiment includes: a detection terminal 1, a main controller 2, a positioning module 3 and an alarm 4.

[0027] The detection terminal 1 is used to collect real-time risk indicators of the battery energy storage container 5 and send the real-time risk indicators to the main controller 2. There can be multiple detection terminals 1, which are installed at different positions of the battery energy storage container 5. The number of detection terminals 1 is determined according to the size of the battery energy storage container 5 to ensure that the risks in every part of the battery energy storage container 5, such as thermal runaway, can be monitored. The detection terminal 1 is provided with a Bluetooth module. The main controller 2 is installed in the battery energy storage container 5. Specifically, a communication gateway can be used as the main controller 2. In addition to the processing chip, the communication gateway also includes communication modules such as Bluetooth modules. The detection terminal 1 sends the real-time risk indicators to the main controller 2 via Bluetooth. The Bluetooth modules of the detection terminal 1 and the main controller 2 are both low-power Bluetooth modules, thereby reducing system energy consumption.

[0028] The positioning module 3 is used to collect the real-time position of the battery energy storage container 5 and send the real-time position to the main controller 2. The positioning module 3 can be a Beidou or GPS module, which is used to locate the real-time position of the battery energy storage container 5 in real time, and send the real-time position to the main controller 2 via Bluetooth or wired mode. The real-time position can be used to determine the product stage of the battery energy storage container 5 later. If the real-time position is consistent with the production plant location (within the allowable error range), it means that the battery energy storage container 5 is in the production and assembly stage. If the real-time position is constantly changing, it means that the battery energy storage container 5 is in the transportation stage. If the real-time position is consistent with the work site location (within the allowable error range), it means that the battery energy storage container 5 is in the on-site installation and commissioning stage.

[0029] The main controller 2 is used to determine the current product stage of the battery energy storage container 5 according to the real-time position, and send an alarm message to the alarm 4 when the real-time risk index exceeds the index threshold corresponding to the current product stage.

[0030] Specifically, the main controller 2 pre-stores information about the production plant location and the work site location. The main controller 2 compares the real-time location with the production plant location and the work site location, and determines whether the real-time location is constantly changing, to determine the current product stage of the battery energy storage container 5. The main controller 2 also pre-stores the indicator threshold corresponding to each product stage, so as to compare the real-time risk indicator of each product stage with the corresponding indicator threshold.

[0031] The detection terminal 1 includes sensors for detecting various risks of the battery energy storage container 5, specifically, including: an acceleration sensor, a temperature and humidity sensor, and / or a combustible gas sensor. Preferably, each detection terminal 1 includes these three sensors, and the real-time risk index includes: a real-time acceleration index collected by the acceleration sensor, combustible gases (for example: CO, H 2 , VOC, etc.) real-time concentration index and real-time temperature and humidity index collected by temperature and humidity sensors. Accordingly, the index thresholds include: acceleration threshold, combustible gas concentration threshold and temperature and humidity threshold.

[0032] The alarm 4 is used to sound an alarm according to the alarm information. Specifically, the alarm 4 can be an audible and visual alarm installed on the outside of the battery energy storage container 5, and is used to sound and light alarm after receiving the alarm information. Preferably, when different real-time risk indicators exceed the corresponding indicator thresholds, different audible and visual alarm methods are used. For example, different voice broadcasts and different colors of light flashing are used to facilitate staff to determine what kind of risk it is according to the alarm method, so as to take corresponding measures more quickly.

[0033] Of course, the battery energy storage container monitoring system also includes a power source, which can be a storage battery (such as a lithium battery), and the power source supplies power to the detection terminal 1, the main controller 2, the positioning module 3 and the alarm 4. It should be noted that this storage battery is a battery dedicated to supply power to the detection terminal 1, the main controller 2, the positioning module 3 and the alarm 4, rather than a battery loaded in the battery energy storage container.

[0034] In the battery energy storage container monitoring system of the present embodiment, the detection terminal 1 collects the real-time risk index of the battery energy storage container 5, the positioning module 3 collects the real-time position of the battery energy storage container 5, and the main controller 2 determines the current product stage of the battery energy storage container 5 according to the real-time position, and sends an alarm message to the alarm 4 when the real-time risk index exceeds the index threshold corresponding to the current product stage, so as to timely discover the risk problems of the battery energy storage container 5 in each product stage of production assembly, transportation and on-site installation and commissioning, and timely alarm.

[0035] In some embodiments, Figure 2 As shown, the battery energy storage container monitoring system also includes: a cloud server 6, in which a binding relationship table of the battery energy storage container ID and the corresponding main controller ID and detection terminal ID is stored. For each battery energy storage container 5 and the main controller 2 and detection terminal 1 installed thereon, there is a corresponding relationship data item of the battery energy storage container ID, the main controller ID and the detection terminal ID, and the relationship data item is stored as a row of data in the binding relationship table, and the binding relationship table can use the battery energy storage container ID and / or the main controller ID as the primary key.

[0036] The main controller 2 is also used to send the alarm information and the corresponding main controller ID (the ID of the main controller 2 that sends the alarm information) and the detection terminal ID (the ID of the detection terminal that detects the risk index related to the alarm information. When the detection terminal 1 sends the real-time risk index to the main controller 2, it will send its own detection terminal ID to the main controller 2) to the cloud server 6. The cloud server 6 is used to find the corresponding battery energy storage container ID according to the main controller ID, and push the battery energy storage container ID, the detection terminal ID and the alarm information to the user terminal, so as to push the alarm information to the staff at all levels in time, avoid the problem of untimely manual reporting, and realize the unified monitoring of multiple battery energy storage containers 5 in the background. The user terminal includes: a terminal computer 7 for monitoring in the background monitoring center, and a mobile terminal 8 of relevant staff or management personnel, such as a smart phone.

[0037] In some embodiments, the binding relationship table also stores an alarm ID corresponding to the battery energy storage container ID, and the alarm information also includes: the alarm ID; the cloud server 6 is also used to send the alarm information to the alarm 4 corresponding to the alarm ID. That is, for each battery energy storage container 5 and the alarm 4 installed thereon, the corresponding relationship data item also includes the alarm ID, so the cloud server 6 can send the alarm information corresponding to the battery energy storage container ID to the alarm 4 of the corresponding alarm ID for alarming, so that the alarm 4 can receive the alarm information sent by the local main controller 2 and the alarm information sent by the cloud server 6, avoiding the problem that the local alarm 4 is not within the Bluetooth coverage range and cannot receive the alarm information.

[0038] In some embodiments, for each battery energy storage container ID, the binding relationship table also stores a location distribution map of the corresponding detection terminal ID on the battery energy storage container 5, and the cloud server 6 is also used to push the battery energy storage container ID, the detection terminal ID and the alarm information to the user terminal, and push the location distribution map corresponding to the battery energy storage container ID to the user terminal. The distribution map plots the specific locations of the detection terminals 1 with different detection terminal IDs on the corresponding battery energy storage container 5, so that the staff can quickly determine the location of the battery energy storage container 5 where the risk problem occurs, so as to take corresponding measures in time.

[0039] In some embodiments, for each battery energy storage container 5, the main controller 2 is further used to send all real-time risk indicators of each product stage collected by the detection terminal 1 to the cloud server 6, and the cloud server stores all real-time risk indicators of each product stage corresponding to different battery energy storage container IDs. In this embodiment, even if no alarm information is generated, all real-time risk indicators of each product stage collected by the detection terminal 1 are stored, and these data can be used as historical data to trace the subsequent abnormal situations of the battery energy storage container 5, so as to find out the cause of the abnormality.

[0040] In some embodiments, the product stage includes: a production and assembly stage, a transportation stage, and an on-site installation and debugging stage, and the indicator threshold corresponding to the transportation stage is lower than the indicator thresholds of the other two stages.

[0041] Specifically, different product stages usually correspond to different external environments and motion scenarios. For example, during the transportation stage, the uneven road surface may cause continuous collisions of batteries in the battery energy storage container 5, resulting in more batteries tipping over or being damaged, thereby rapidly releasing flammable gases or causing thermal runaway at a faster rate. For the transportation stage, compared with the other two product stages, the battery energy storage container 5 is only in motion during the hoisting process, and the speed is slower than that of the transportation stage. Relatively low indicator thresholds can be set, such as relatively low acceleration thresholds, flammable gas concentration thresholds, and temperature and humidity thresholds, so that risks can be discovered and alarmed more timely, and staff can take timely measures to avoid accidents. Therefore, different indicator thresholds corresponding to different product stages can achieve risk monitoring and alarms more timely and accurately.

[0042] In some embodiments, the detection terminal 1 includes: an acceleration sensor, the real-time risk index includes a real-time acceleration index collected by the acceleration sensor, the index threshold includes an acceleration threshold, and the acceleration threshold corresponding to the transportation stage is less than the acceleration thresholds of the other two stages. Specifically, both the production assembly and the on-site installation and commissioning involve the process of hoisting the battery energy storage container 5. During the transportation stage, the battery energy storage container 5 moves with the movement of the vehicle and the uneven road surface. The battery energy storage container 5 has both horizontal and vertical movements. Moreover, the horizontal speed of the battery energy storage container 5 is faster during the transportation stage than during the hoisting process during the production assembly and on-site installation and commissioning stages. Since the up and down bumps of the road surface are more frequent, the collision of the battery is also more frequent. Therefore, for the transportation stage, a smaller acceleration threshold can be set, and corresponding measures can be taken in time after the real-time acceleration index reaches the acceleration threshold, such as slowing down the vehicle, so as to avoid accidents caused by battery collisions.

[0043] Furthermore, during the transportation phase, the main controller 2 is also used to determine the current horizontal movement speed of the battery energy storage container 5 (i.e., the speed of the transport vehicle, the distance between the two adjacent real-time positions divided by the time difference between the two adjacent real-time positions) according to the two adjacent real-time positions, and send an acceleration abnormality alarm message to the alarm 4 when the real-time acceleration index exceeds the acceleration threshold corresponding to the current horizontal movement speed. The faster the movement speed of the battery energy storage container 5, the smaller the speed threshold. Since the uneven road surface will cause the battery to move up and down, and the battery also has a faster horizontal speed with the vehicle, making the collision caused by the up and down movement more intense, therefore, in this embodiment, different acceleration thresholds are set for different horizontal movement speeds, so as to more accurately monitor the collision risk of the battery energy storage container 5 at different driving speeds during the transportation phase to avoid accidents. Specifically, the main controller 2 pre-stores acceleration thresholds corresponding to different horizontal movement speed ranges, so as to determine the corresponding acceleration threshold according to the current horizontal movement speed.

[0044] In some embodiments, the real-time acceleration index includes: a forward acceleration index, a lateral acceleration index and a vertical acceleration index, and the acceleration threshold includes: a forward acceleration threshold, a lateral acceleration threshold and a vertical acceleration threshold. Among them, the forward direction refers to the direction of vehicle travel, the lateral direction refers to the direction perpendicular to the forward direction on the horizontal plane, and the vertical direction refers to the direction perpendicular to the horizontal plane.

[0045] In this embodiment, when the horizontal movement speed of the battery energy storage container 5 is the same, the forward acceleration threshold, the lateral acceleration threshold and the vertical acceleration threshold may be the same or different. When the acceleration index in any direction exceeds the acceleration threshold in the corresponding direction, the main controller 2 sends an abnormal acceleration alarm message to the alarm 4, thereby more accurately and timely monitoring the collision risk of the battery energy storage container 5 during the transportation stage to avoid accidents.

[0046] In some embodiments, the main controller 2 is further used to send an acceleration abnormality alarm message to the driver terminal (the driver's smart phone) when the real-time acceleration index exceeds the acceleration threshold corresponding to the current horizontal movement speed, that is, to inform the driver of the acceleration abnormality alarm message, so that the driver can take corresponding measures in time after receiving the acceleration abnormality alarm message, such as: slowing down or avoiding potholes during driving, so as to avoid safety accidents such as thermal runaway caused by aggravated collision or large-scale dumping of batteries in the battery energy storage container 5.

[0047] Specifically, a Bluetooth connection can be established between the main controller 2 and the driver terminal, and the acceleration abnormality alarm information can be sent to the driver terminal via Bluetooth. Before transportation, the driver terminal ID can be stored in the above-mentioned binding relationship table of the cloud server 6. For all battery energy storage containers 5 on any vehicle, a driver terminal ID field is added to the relationship data item of the corresponding battery energy storage container ID, thereby establishing an association between the battery energy storage container ID and the driver terminal ID. After receiving the acceleration abnormality alarm information, the cloud server 6 pushes the acceleration abnormality alarm information and the corresponding battery energy storage container ID to the driver terminal.

[0048] Through the description of the above implementation methods, those skilled in the art can clearly understand that each implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each embodiment or some parts of the embodiments.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
