Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0044] With the development of science and technology, on-line monitoring technology of storage batteries has begun to be widely applied to the monitoring of storage batteries in data centers. This new type of storage battery detection method can accurately monitor key parameters such as the voltage, current, ripple coefficient, and ambient temperature of the storage battery pack, providing strong support for the maintenance and management of storage batteries.

[0045] During the charging and discharging process of energy storage batteries, due to internal chemical reactions and external environmental factors, thermal runaway may occur, resulting in a sharp rise in battery temperature, posing a great threat to the safety of personnel's lives and property. Therefore, it is crucial to monitor the temperature of the storage battery compartment in real time.

[0046] Defects of the prior art:

[0047] 1. Inaccurate temperature monitoring;

[0048] Due to the complex environment in the storage battery compartment, there may be uneven temperature distribution, resulting in the monitoring equipment being unable to accurately reflect the overall temperature condition.

[0049] 2. Equipment failure or aging;

[0050] The temperature monitoring equipment itself may malfunction due to aging, damage, or incorrect operation procedures, thus affecting the accuracy of the monitoring results.

[0051] 3. Greatly affected by the environment;

[0052] There may be other interference factors in the storage battery compartment, such as electromagnetic interference, vibration, etc., which may affect the normal operation of the temperature monitoring equipment.

[0053] 4. Lack of real-time and continuity;

[0054] Some temperature monitoring technologies may not be able to achieve real-time and continuous temperature monitoring, resulting in the inability to detect abnormal temperature changes in a timely manner, thus increasing potential safety hazards.

[0055] 5. Difficult to maintain and calibrate;

[0056] The temperature monitoring equipment needs to be regularly maintained and calibrated to ensure its accuracy, but it may be difficult to achieve in the storage battery compartment due to space limitations or complex operations.

[0057] Therefore, the present application provides a method for temperature management of an electric ship battery compartment, which solves the above problems existing in the prior art and can obtain relatively accurate battery temperatures.

[0058] The following describes the preferred embodiments of the present application with reference to the accompanying drawings of the specification. It should be understood that the preferred embodiments described herein are only for illustrating and explaining the present application, and are not used to limit the present application. And without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0059] Figure 2 It is a schematic flowchart of a method for temperature management of an electric ship battery compartment provided by an embodiment of the present application. As Figure 2 shown, this method is applied to a battery compartment management system including a data acquisition unit, a data processing unit, an alarm unit, an adjustment unit, and a communication unit. This method may include:

[0060] Step S210: The data acquisition unit collects the battery temperatures of different nodes on the ship battery compartment and sends the battery temperatures to the data processing unit.

[0061] Among them, the data acquisition unit includes a distributed optical fiber sensor and an infrared thermal imaging camera; the battery temperatures include the first battery temperatures of each node collected by the distributed optical fiber sensor and the second battery temperatures of each node collected by the infrared thermal imaging camera;

[0062] Specifically, a distributed optical fiber temperature sensor and an infrared thermal imaging camera are respectively arranged for each row of battery packs in the ship battery compartment.

[0063] The distributed optical fiber temperature sensor uses the Raman scattering effect in the optical fiber to detect temperature. Through a single optical fiber, continuous temperature monitoring of an entire row of battery packs can be achieved, ensuring that no monitoring node is missed or repeatedly monitored, and at the same time avoiding mutual interference between different monitoring nodes. In other words, this sensor can seamlessly cover all battery packs that need to be monitored, providing users with accurate and reliable temperature data, and ensuring the efficiency and accuracy of the monitoring process. This not only improves the comprehensiveness of temperature monitoring, but also enhances the reliability and safety of the system.

[0064] Using an infrared thermal imaging camera to collect data can efficiently obtain the temperature information of each node on the battery surface and convert it into a visual thermal image. This non-invasive detection method not only improves work efficiency but also ensures measurement accuracy. By analyzing these thermal images, the system can quickly identify any areas that may have overheating problems, provide timely warnings and support further data processing and fault diagnosis. This method greatly facilitates the real-time monitoring and management of the battery state and helps prevent potential safety hazards.

[0065] Step S220: For any node, the processing unit processes the first battery temperature and the second battery temperature of the node to obtain the target battery temperature of the node; and processes multiple target battery temperatures of the node within a preset period to obtain temperature change data; when the temperature change data meets the warning condition, a warning message is generated and sent to the alarm unit.

[0066] Specifically, there are two ways to calculate the target battery temperature from the first battery temperature and the second battery temperature, which may include:

[0067] A. Using a first preset algorithm to calculate the first battery temperature and the second battery temperature to obtain the target battery temperature;

[0068] The first preset algorithm is:

[0069]

[0070] Where T 融合 is the target battery temperature, T DFOTS is the first battery temperature, T IR is the second battery temperature, is the temperature gradient, and S hotspot is the hot spot area.

[0071] The calculation method of the temperature gradient is:

[0072]

[0073] Where Δx is the fiber optic spatial resolution, and T i and T i+1 are the second temperatures of adjacent nodes.

[0074] B. Using a second preset algorithm to calculate the first battery temperature and the second battery temperature to obtain the target battery temperature;

[0075] Specifically, in order to improve the calculation accuracy, a distributed fiber optic temperature sensor and an infrared thermal imaging camera can be set to collect the temperature of the same battery multiple times at the same time point, so as to obtain multiple first battery temperatures and multiple second battery temperatures.

[0076] After that, since the collected original temperature data may contain some outliers or noise, it is necessary to sort out and clean these data. This step may include operations such as removing obviously incorrect data points and filling in missing values to ensure the accuracy of subsequent analysis.

[0077] The second preset algorithm is:

[0078]

[0079] Among them, T 融合 is the target battery temperature, T DFOTS is the first battery temperature, T IR is the second battery temperature, w DFOTS is the first weight of the first battery temperature, w IR is the second weight of the second battery temperature.

[0080] Furthermore, the calculation method of the first weight is:

[0081] The calculation method of the second weight is

[0082] Among them, σ DFOTS is the standard deviation of the first battery temperature, σ IR is the standard deviation of the second battery temperature.

[0083] After that, process the multiple target battery temperatures of the node within a preset time period, and the obtained temperature change data may include:

[0084] First, within a preset time period (such as every minute, every 5 minutes, etc.), collect the target battery temperatures of each node.

[0085] According to the target battery temperature, calculate the temperature change of each node's battery within the preset time period. The temperature change rate of each battery can be determined by calculating the temperature difference between adjacent time points, or calculate the average temperature and its change trend within the entire time period.

[0086] Visualize the processed temperature change data, such as plotting a temperature change curve of temperature over time, so as to intuitively observe the temperature change pattern of each battery pack.

[0087] In some embodiments, process the temperature change curves of multiple preset time periods to obtain a temperature change trend graph; for the data within each preset time period, calculate the corresponding temperature change index. It can be statistical quantities such as average temperature, maximum / minimum temperature, standard deviation of temperature, etc., and integrate the data from different time periods to obtain a temperature change trend graph.

[0088] In another embodiment, based on the temperature change trend graph of each node, predict the predicted temperature of the battery in the future time period. Adopt a multi-variable fusion model to process the temperatures corresponding to each time point in the temperature change trend graph, and output the predicted temperature of the battery in the future time period. Specifically, the input data of the input layer of the multi-variable fusion model is: the temperature data corresponding to each time point. Environmental variables (ambient temperature, current, SOC). Spatial features (temperature gradient, hot spot distribution). The data output by the output layer is: the temperature prediction in the future time period.

[0089] In some embodiments, after determining that the temperature change data meets the temperature adjustment threshold, the processing unit generates adjustment information and sends the adjustment information to the adjustment unit; the temperature adjustment threshold includes a primary threshold and a secondary threshold; the primary threshold is less than the secondary threshold.

[0090] The adjustment unit adjusts the battery temperature of the corresponding node in the ship's battery compartment according to the adjustment information, which may include:

[0091] The processing unit processes the temperature change data of the node within a preset time period to obtain the average temperature.

[0092] If the average temperature meets the primary threshold, the first adjustment scheme is started; the control logic for the primary threshold response (fan control): when θl evel2 ≥T avg >θl evel1 is satisfied, the fan is started for cooling. After that, the temperature change rate after adjustment is calculated every 10 seconds. If ΔT eff <0.5℃ / s, ΔT eff <0.5℃ / s, it is considered that the adjustment is effective, otherwise it is determined as a failure.

[0093] If the average temperature meets the secondary threshold, the second adjustment scheme is started; the control logic for the secondary threshold response (triggering liquid cooling): when T avg >θl evel2 is satisfied, liquid cooling is triggered for cooling. After that, the temperature change rate after adjustment is calculated every 10 seconds. If ΔT eff <0.5℃ / s, ΔT eff <0.5℃ / s, it is considered that the adjustment is effective, otherwise it is determined as a failure.

[0094] When the temperature change data meets the warning condition, a warning message is generated and sent to the alarm unit. Specifically, the warning condition may be that when the temperature change data exceeds the preset safety range, a warning message is generated, or a warning condition based on the temperature change rate is set, or for the situation of maintaining within an unsatisfactory but not yet emergency temperature range for a long time, the duration can be set as the warning condition.

[0095] The alarm unit can give an alarm according to the warning message.

[0096] Since the normal operating temperature range of the battery is 20 - 40°C and the optimal operating temperature is 25°C. When the temperature rises by 5°C each time, the service life of the battery is reduced by 10%, and thermal runaway is likely to occur. The high-temperature environment will shorten the service life of the battery and even pose a fire risk. Therefore, by monitoring the temperature of the single battery, it can be ensured that the battery operates within an appropriate temperature range and its service life is extended.

[0097] In some embodiments, the communication unit of the present application can be linked with fire-fighting facilities. When the temperature change data meets the conditions for activating the fire-fighting facilities, the communication unit can remotely trigger the fire-fighting facilities for emergency treatment.

[0098] In this way, when the battery undergoes thermal runaway, the temperature will rise sharply. By monitoring the temperature change in real time, abnormal conditions can be detected in the early stage of thermal runaway, and measures can be taken in a timely manner to prevent accidents.

[0099] In another embodiment, the present application can be connected to a remote monitoring center through a communication unit, and data can be transmitted to the remote monitoring center or the device of the management personnel through the network to achieve remote monitoring and management.

[0100] In another embodiment, temperature monitoring can be combined with other monitoring parameters (such as voltage, current, humidity, etc.) to form a comprehensive battery state monitoring system. In this way, the health status and potential risks of the battery can be evaluated more accurately.

[0101] The present application provides a method for managing the temperature of an electric ship battery compartment. The method is applied to a battery compartment management system including a data acquisition unit, a data processing unit, and an alarm unit. The method includes: the data acquisition unit acquires the battery temperatures of different nodes on the ship battery compartment and sends the battery temperatures to the data processing unit; the data acquisition unit includes a distributed optical fiber sensor and an infrared thermal imaging camera; the battery temperature includes the first battery temperature of each node acquired by the distributed optical fiber sensor and the second battery temperature of each node acquired by the infrared thermal imaging camera; the processing unit processes the first battery temperature and the second battery temperature of a node to obtain the target battery temperature of the node; and processes multiple target battery temperatures of the node within a preset time period to obtain temperature change data; when the temperature change data meets the warning conditions, a warning message is generated and sent to the alarm unit; the alarm unit alarms according to the warning message. The combination of the distributed optical fiber sensor and the infrared thermal imaging camera in this method ensures high-precision and stable temperature monitoring. A single optical fiber can continuously cover an entire row of battery packs, achieving comprehensive and non-missing temperature monitoring. It can monitor the battery temperature in real time and immediately send a warning signal when abnormal, providing sufficient time for management personnel to take measures. The infrared thermal imaging camera can generate a temperature distribution image of the battery compartment, enabling management personnel to intuitively understand the temperature status of the battery compartment.
