Description

Technical Field

[0001] The utility model relates to the technical field of new energy storage systems, and in particular to an abnormal temperature warning device for batteries in energy storage systems. Background Art

[0002] With the continuous development of new energy technologies, energy storage system battery packs have been widely used in various fields. However, during the use of battery packs, the battery temperature and voltage may be abnormal due to reasons such as excessively high ambient temperature and battery aging, which may lead to safety issues.

[0003] Therefore, in the prior art, the battery pack of the energy storage system will be monitored for abnormalities. The conventional method is to detect the temperature of the entire battery pack through a single temperature sensor, but this method cannot determine the specific abnormal area in the battery pack, nor can it locate the faulty battery cell; in addition, when replacing damaged components, the conventional integrated design often requires the entire device to be disassembled for maintenance, which is not only time-consuming and labor-intensive, but may also cause unnecessary damage to other parts of the device. Utility Model Content

[0004] The utility model aims to provide a temperature abnormality warning device for a battery in an energy storage system, which is used to solve the technical problem in the prior art that the temperature abnormality of the battery in the energy storage system cannot be located and detected.

[0005] The basic scheme provided by the utility model is: a temperature abnormality warning device for a battery in an energy storage system, comprising a shell component forming a hollow cavity inside and a temperature detection unit;

[0006] The hollow cavity of the outer shell member has a built-in container; the interior of the container is divided into a plurality of storage cavities for built-in battery components by a plurality of partition members;

[0007] The temperature detection unit includes a substrate component and a plurality of temperature collection components arranged on a first side of the substrate component; the first side faces the cavity opening of the storage cavity, and each cavity opening of the storage cavity corresponds to at least one temperature collection component;

[0008] The temperature detection unit is connected to the housing member through a substrate member.

[0009] The working principle and advantages of the utility model are as follows: the battery components are separated and independently installed by means of containers and storage cavities. Since the heat is usually dissipated from the opening position when the battery components are damaged, when the battery components are placed in each storage cavity, the opening of the battery components is close to the cavity opening of the storage cavity. By setting the temperature collection component at the corresponding position of the cavity opening of each storage cavity, the temperature of the battery components in each storage cavity can be independently collected and monitored.

[0010] Compared with the prior art, this solution has a reasonable structure, is easy to maintain, provides all-round protection for independent battery components, and realizes accurate temperature data collection and abnormal fault location.

[0011] Specifically, the outer shell component serves as a protective layer for the entire early warning device, not only providing physical protection, but also supporting and fixing the internal components; the outer shell component has a certain strength and rigidity to ensure that the internal components can be well protected under normal working conditions and in extreme environments.

[0012] The container utilizes partition components to form a partition design of an independent storage cavity, which not only achieves stable internal battery components but also realizes independent storage and independent maintenance of the battery components, thereby avoiding a chain reaction on other batteries when a battery cell fails, while also facilitating maintenance, improving maintenance efficiency, and reducing maintenance costs; in addition, the special setting of the partition components can effectively reduce heat transfer between batteries, ensure that the operating temperature of each battery will not be affected by adjacent batteries, and ensure the real-time and accurate temperature data of individual battery components.

[0013] The temperature data of each battery component can be transmitted to the corresponding monitoring terminal in an appropriate manner. Once an abnormal temperature is detected, a fault location alarm is issued, allowing staff to immediately determine the location of the faulty battery component or abnormal area, and conduct a comprehensive analysis to obtain appropriate measures to deal with it, thereby improving maintenance efficiency. At the same time, based on timely and accurate fault handling, the operational safety performance of the energy storage system is improved.

[0014] Furthermore, the thermal conductivity of the partition member is 0.035-0.045 W / (m·K).

[0015] Furthermore, the partition member is made of glass fiber.

[0016] Furthermore, the container is detachably connected to the outer shell component via a connecting piece.

[0017] Furthermore, a data processing component and an early warning component which are communicatively connected with the plurality of temperature acquisition components are arranged on a second side surface of the substrate component away from the cavity opening of the storage cavity.

[0018] Furthermore, the substrate component is sealed and connected to the housing component.

[0019] Furthermore, the substrate component is made of transparent material.

[0020] Furthermore, the temperature acquisition component is a thermistor, a thermocouple and / or a temperature sensor.

[0021] Furthermore, the partitioning member is separated by a double-layer partitioning plate with a first spacing, wherein the first spacing is controlled to be 5-8 mm.

[0022] Furthermore, a plurality of protruding structures are arranged on the substrate component, and the protruding structures are matched with the cavity openings of the receiving cavity, and one protruding structure corresponds to one cavity opening of the receiving cavity.

[0028] The following is a further detailed description through specific implementation methods:

[0029] The symbols in the drawings of the specification include: a housing member 1 , a threaded hole 11 , a container 2 , a partition member 3 , a storage cavity 4 , a substrate member 5 , a first side surface 51 , a second side surface 52 , and a temperature collection component 53 .

[0030] Embodiment 1

[0031] Basically as attached Figure 1 and Figure 2 As shown: A battery temperature abnormality warning device for an energy storage system includes a shell component 1 with a hollow cavity formed inside and a temperature detection unit.

[0032] like Figure 1 As shown, the outer shell component 1 serves as a protective layer for the entire warning device, not only providing physical protection, but also supporting and fixing the internal components. The outer shell component 1 needs to have a certain strength and rigidity to ensure that the internal components can be well protected under normal working conditions and extreme environments.

[0033] It should be noted that the material of the outer shell component 1 is adaptively selected according to the application environment of the battery of the energy storage system. The overall size of the outer shell component 1 should be determined according to the number and size of the adapted battery and the internal storage cavity 4 to ensure that all battery components can be properly placed. No specific restrictions are made on the material and size of the outer shell component 1. The outer shell can be designed as a rectangular structure with an opening on the top, and can preferably be 1000mm long, 800mm wide, and 500mm high. This size can accommodate a suitable number and size of storage cavities 4, adapt to battery components of multiple specifications, and meet the energy storage system configuration of different application scenarios, with high versatility.

[0034] like Figure 2 As shown, the hollow cavity of the shell member 1 contains a container 2; the container 2 is detachably connected to the cavity of the shell member 1 through a connecting piece. When the container 2 is taken out of the shell member 1, as shown in FIG. Figure 1 As shown, in the embodiment, a positioning groove is provided on the outer surface of the container 2, and a threaded hole 11 is provided on the surface of the shell member 1. When the container 2 is embedded in the shell member 1, the threaded hole 11 is aligned with the positioning groove, and a connecting bolt member can pass through the threaded hole and one end extends to the positioning groove to complete the fixation of the position between the shell member and the container. During long-term operation, some components of the battery of the energy storage system may need to be inspected or replaced. Compared with the existing integrated structure, the detachable connection between the container 2 and the shell member 1 enables maintenance personnel to easily remove the container 2 from the shell member 1 to inspect, repair or replace the internal battery or other components, which greatly improves the maintenance efficiency. The detachable connection design of the container 2 significantly improves the maintenance convenience of the device.

[0035] The interior of the container 2 is divided by a plurality of partition members 3 to form a plurality of storage chambers 4 for built-in battery components. Preferably, the storage chambers 4 are single-layered and evenly distributed. A single battery component can be directly embedded in a storage chamber 4. Each battery component is isolated by the partition design, thereby avoiding a chain reaction on other batteries when a battery fails. The size of each storage chamber 4 should be designed according to the size of the battery component placed. The inner wall size of the storage chamber 4 is adapted to the outer wall size of the battery component. The inner wall size of the storage chamber 4 can be designed to be 200 mm long, 150 mm wide, and 100 mm high to accommodate the common battery component size. Such a design can ensure the stable installation and heat dissipation requirements of the battery components of the energy storage system during use, and is conducive to uniform temperature distribution and accurate monitoring.

[0036] The partition member 3 is connected to the container. In this embodiment, the partition member 3 is first molded and manufactured, and an adhesive is applied to the bottom of the partition member 3 to adhere it to the bottom of the container. The partition member 3 has excellent thermal insulation performance, and its thermal conductivity is 0.035-0.045W / (m·K). It is made of a material with a low thermal conductivity. The partition member 3 can effectively reduce the heat transfer between batteries and ensure that the operating temperature of each battery will not be affected by adjacent batteries. The material of the partition member 3 is glass fiber. Glass fiber is an inorganic non-metallic material, mainly composed of silicate minerals that are melted at high temperature and then quickly drawn into filaments through a special nozzle. Glass fiber has high tensile strength and modulus, can withstand large tensile forces without breaking, and has stability during use. In addition, glass fiber has excellent corrosion resistance and can resist erosion by most chemical substances.

[0037] The temperature detection unit is responsible for real-time monitoring and processing of the temperature in each storage cavity 4 . The temperature detection unit includes a substrate component 5 and a plurality of temperature collection components 53 arranged on a first side surface 51 of the substrate component 5 .

[0038] like Figure 3 As shown, the temperature detection unit is connected to the housing member 1 through the substrate member 5, and a sealed connection can be adopted. The sealing design of the substrate member 5 can prevent external dust, moisture or other contaminants from entering the interior of the device, thereby protecting the battery member and the temperature detection unit from environmental factors. The substrate member 5 can be made of a transparent material, and the internal situation of the storage cavity 4 can be directly observed, providing another way to monitor the safety performance of the battery. The inside of the dotted frame is divided into a common module architecture, which is simply indicated without special meaning.

[0039] like Figure 4 As shown, the first side surface 51 faces the cavity openings of several storage cavities 4, and at least one temperature collection component 53 is arranged corresponding to the cavity opening of each storage cavity 4. It can be selected to correspond one to one, or two temperature collection components 53 can be arranged corresponding to the storage cavity at an important position, so as to strengthen the double protection of the detection of important positions, avoid the failure of a single temperature collection component 53, and lose the monitoring of important positions, resulting in safety accidents; because the damaged battery components usually dissipate heat from the opening position, when the battery components are placed in each storage cavity 4, the opening of the battery components is close to the cavity opening of the storage cavity 4, and the temperature collection component 53 is arranged corresponding to the cavity opening position of each storage cavity 4. These components are accurately placed at the corresponding positions of each storage cavity 4, so as to realize independent collection and monitoring of the temperature of the battery components in each storage cavity 4, and ensure that the working temperature of each battery component can be accurately monitored; each storage cavity 4 corresponds to at least one temperature collection component 53, even if a battery fails or is abnormal, it can be discovered and handled in time, thereby improving the accuracy and reliability of temperature detection.

[0040] like Figure 3 and Figure 5 As shown, a data processing component and an early warning component which are communicatively connected to a plurality of temperature acquisition components 53 are arranged on the second side surface 52 of the substrate member 5 away from the cavity opening of the storage cavity 4. The temperature acquisition component 53 collects the temperature data in the corresponding storage cavity 4 in real time, and transmits the data to the data processing component for analysis and processing. Once an abnormal temperature is detected, the early warning component will immediately sound an alarm to remind the staff to take timely measures to deal with it.

[0041] The temperature acquisition component 53 may use a thermistor, a thermocouple or other types of temperature sensors, which can respond to temperature changes quickly and accurately, and convert temperature signals into electrical signals for subsequent processing. When specifically arranged, the temperature acquisition components at all locations may select the same type of product, or different types of products, to avoid the failure of a single batch of products at the same time, resulting in invalid detection. The data processing component may be a product with the model number IN1188, and the early warning component may be a product with the model number MTK13-R4610-S01. The data processing component is responsible for receiving electrical signals from the temperature acquisition component 53, and amplifying, filtering, digitizing, and other processing of these signals through a built-in microprocessor or a dedicated integrated circuit. Once the data processing component detects that the temperature in a storage cavity 4 exceeds the preset safety range, the early warning component will immediately start the alarm program. The alarm method may include sound alarm, flashing lights, and sending alarm information to the remote monitoring center through the wireless communication component to promptly discover potential safety risks.

[0042] The embodiment provides an energy storage system battery temperature abnormality warning device. Compared with the prior art, the solution has a reasonable structure, is easy to maintain, provides multi-directional protection for battery components, and realizes accurate temperature data collection and abnormal fault location.

[0043] As the protective layer of the entire early warning device, the shell component not only provides physical protection, but also plays the role of supporting and fixing the internal components; the shell component has a certain strength and rigidity to ensure that the internal components can be well protected under normal working conditions and extreme environments. The container uses a partition component to form an independent storage chamber partition design, which realizes the stability of the built-in battery components while realizing independent storage and independent maintenance of the battery components, thereby avoiding the chain effect of a battery cell failure on other batteries, and facilitating maintenance, improving maintenance efficiency, and reducing maintenance costs; in addition, the special setting of the partition component can effectively reduce the heat transfer between batteries, ensure that the operating temperature of each battery will not be affected by the adjacent batteries, and ensure the real-time and accurate temperature data of a single battery component. The temperature data of each battery component can be transmitted to the corresponding monitoring end in an appropriate manner. Once an abnormal temperature is detected, a fault location alarm is issued, allowing the staff to determine the location of the faulty battery component or the abnormal area in the first time, and comprehensively analyze and obtain the corresponding appropriate measures for processing, improve maintenance efficiency, and at the same time improve the operation safety performance of the energy storage system based on timely and accurate fault handling.

[0044] Embodiment 2

[0045] Different from the first embodiment, the partition component is separated by a double-layer partition plate with a first spacing, and the first spacing is controlled at 5-8mm. The first spacing can be used to form a gap space between adjacent storage cavities, and this gap space can be used to dissipate heat, thereby reducing the mutual influence of heat during the operation of adjacent battery components.

[0046] Embodiment 3

[0047] What is different from the first embodiment is that a plurality of protruding structures are arranged on the substrate component, and one protruding structure corresponds to the cavity opening of a storage cavity. The protruding structure is adapted to the cavity opening of the storage cavity. When the substrate component is installed on the shell component, the cavity opening can be sealed by utilizing the protruding structure, so that when a single temperature acquisition component performs temperature detection on a battery component in a corresponding storage cavity, it is not affected by adjacent temperatures, thereby improving the accuracy of a single temperature detection.

[0048] Embodiment 4

[0049] What is different from the first embodiment is that a temperature collection component is added in the middle of each storage cavity, and the temperature collection point of a single battery component is increased, so that more accurate temperature detection of a single battery component can be achieved; for a single battery component, by comparing the temperature data at different points, it is possible to detect whether it is a false alarm; by comparing and analyzing the temperature detection data at the middle positions of adjacent battery components, it is possible to determine whether it is a false alarm and the scope of influence; by increasing the number of detection points, the entire temperature detection data is richer, the analysis of abnormal temperature of the energy storage battery is more multi-dimensional and comprehensive, and more suitable processing measures can be formed.

[0050] Embodiment 5

[0051] Different from the first embodiment, the container is not a whole container that matches the shape of the inner wall of the shell member, but a plurality of containers arranged in a preset manner in the hollow cavity of the shell member, and then separated and divided based on a single container.

[0052] The setting of independent containers makes disassembly and maintenance more flexible, and abnormal battery components in a single container can be maintained independently; several containers can be evenly distributed in a matrix, such as 6 rows and 10 columns, to maximize the utilization of the hollow cavity and place as many battery components as possible.

[0053] The partitioning of a single container can make the partition components smaller and easier to install. Two partition components can be set in a single container to evenly form three storage cavities to ensure that the size of a single container is appropriate and the number of battery components placed in a single container is appropriate. When multiple continuous battery components are involved in the abnormal area, the number of split containers can be maintained appropriately, and the fault can be quickly isolated.

[0054] The above is only an embodiment of the utility model. The common sense such as the known specific structure and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
