When in use, the operator can easily start the infrared temperature detection system through a simple operation process to realize accurate monitoring and real-time display of the battery module temperature. First, the operator arranges the infrared module in the five key positions of the battery module, namely the four corners and the center position, in a five-point manner, and installs it around or in a suitable position inside the battery module to ensure that the infrared module can effectively cover the entire battery module area.

[0053] In order to further realize the comprehensive monitoring of the temperature of the battery module, to detect temperature abnormalities in time, and to improve the safety and stability of the system, the infrared module includes a wide-angle infrared thermal imager for realizing the comprehensive monitoring of the temperature of the battery module. Specifically, the infrared module is arranged at five key positions of the battery module, namely the four corners and the center, to ensure that the temperature of each area of ​​the battery module can be monitored. When in use, the infrared module is arranged at five key positions of the battery module, namely the four corners and the center. This five-point layout design ensures the comprehensive monitoring of the temperature of each area of ​​the battery module, so that temperature changes can be detected in time whether it is the edge area or the center area of ​​the battery module. This comprehensive monitoring design not only helps to improve the safety of the system, but also can take measures quickly in the case of abnormal temperature to protect the normal operation of the battery module and extend its service life. In addition, as a sensor, the wide-angle infrared thermal imager has high sensitivity and resolution, and can provide more accurate and comprehensive temperature data, so that the monitoring results are more reliable and accurate. The layout of the infrared module and the selection of the sensor fully consider the structural characteristics and working environment of the battery module, so that the system has better applicability and stability.

[0054] In order to further realize the flexible connection between the infrared module and the microcontroller unit, i.e., the MCU unit, improve the compatibility and scalability of the system, and provide more options for data transmission, the infrared module and the microcontroller unit, i.e., the MCU unit, are connected through the communication mode of CAN, SPI or UART. When in use, the flexible connection mode between the infrared module and the microcontroller unit, i.e., the MCU unit in the infrared temperature detection system is an important design consideration to ensure the compatibility and scalability of the system. In order to realize the flexible connection mode and provide more data transmission options, the infrared module and the microcontroller unit, i.e., the MCU unit in the utility model adopt a variety of communication modes, including CAN, SPI or UART. CAN (Controller Area Network), SPI (Serial Peripheral Interface) and UART (Universal Asynchronous Receiver / Transmitter) are common communication protocols, which are widely used in the fields of industrial control and data transmission.

For example, for scenes requiring high-speed data transmission and multi-device connection, CAN or SPI communication modes can be selected; while for simple data transmission and device connection, UART communication mode is more suitable. Through this flexible connection method, the infrared temperature detection system can better adapt to different application scenarios and system requirements, and also provide more possibilities for future system upgrades and expansions. This design solution helps to improve the flexibility and scalability of the system, and further enhances the overall performance and use effect of the system.

[0055] In order to further enhance the subsequent data analysis and processing capabilities, and to achieve persistent storage of temperature data to ensure that data is not lost, the system also includes a storage unit connected to the microcontroller unit, i.e., the MCU unit, for storing the temperature monitored by the infrared module. When in use, the storage unit connected to the microcontroller unit, i.e., the MCU unit, plays a key role in achieving persistent storage of temperature data collected by the infrared module to ensure that data is not lost.

They can achieve high-speed data transmission and are suitable for scenarios with high data response speed requirements in real-time monitoring systems. Connecting the storage unit and the microcontroller unit, i.e., the MCU unit, through an SPI or I2C interface can achieve fast and stable data transmission. The full-duplex communication mode and high-speed transmission rate of the SPI interface are suitable for scenarios with high data response speed requirements, while the I2C interface is simple and flexible, and is suitable for connecting multiple devices and realizing data transmission. Using an SPI or I2C interface to connect the storage unit and the microcontroller unit, i.e., the MCU unit, not only improves the data transmission speed and reliability of the system, but also simplifies the design and debugging process of the system, providing more possibilities for system performance optimization and upgrade.

[0057] Optionally, the system further includes an alarm unit, which is connected to the microcontroller module and is activated when a temperature anomaly or an infrared module failure is detected. The alarm unit can send an alarm to an external system in a timely manner to remind an operator or other system to take corresponding countermeasures.

[0058] The utility model also provides an infrared module for monitoring the temperature of a battery module, including an infrared module using a wide-angle infrared thermal imager, and the wide-angle infrared thermal imager adopts a multi-point layout method to monitor the temperature of the battery module in real time, so that the entire area of ​​the battery module is monitored. In this embodiment, a five-point layout method is used for explanation. Figure 1As shown, the infrared module adopts a five-point layout mode, that is, the infrared modules are distributed at the four corners and the center of the battery module, namely the first position A01, the second position A02, the third position A03, the fourth position A04 and the center position A05. When in use, the infrared module provided by the utility model realizes comprehensive monitoring of the temperature of the battery module by adopting a wide-angle infrared thermal imager and a five-point layout mode, ensuring the timely acquisition and accurate monitoring of the temperature of each area of ​​the battery module. First, the infrared module using a wide-angle infrared thermal imager can obtain the temperature data of the battery module by receiving infrared radiation without contacting the surface of the battery module. This non-contact monitoring method avoids damage or interference to the battery module, and can obtain the temperature of the battery module in real time, ensuring the timeliness and accuracy of monitoring. Secondly, the infrared module using a five-point layout mode distributes the infrared sensors at the four corners and the center of the battery module, which can realize comprehensive monitoring of the temperature of each area of ​​the battery module. Such a layout design can effectively cover the surface of the entire battery module, ensuring a comprehensive grasp of the temperature changes of each part of the battery module. By adopting a wide-angle infrared thermal imager and a five-point layout, the infrared module provided by the utility model can realize comprehensive monitoring of the battery module temperature, providing an important guarantee for the safe operation of the battery system. At the same time, the design is also simple to use and easy to operate, suitable for various battery module monitoring scenarios, with high practical value and broad application prospects.

[0059] In order to further improve the accuracy and reliability of the temperature measurement of the infrared module and ensure the accuracy of the monitoring data, the infrared module includes a temperature calibration unit for calibrating the temperature data collected by the infrared module. Specifically, the temperature calibration unit includes a temperature sensor, a standard temperature source, a comparison circuit and a calibration controller. First, the temperature sensor is responsible for real-time monitoring of the temperature of the temperature calibration unit itself to provide ambient temperature information. Secondly, the standard temperature source is a heat source with a known accurate temperature, which is used to provide a reliable reference temperature. The comparison circuit is used to compare the ambient temperature measured by the temperature sensor with the temperature of the standard temperature source and calculate the calibration parameters. Finally, the calibration controller is responsible for adjusting the temperature measurement value of the infrared module according to the comparison result to ensure the accuracy and stability of the measurement data. Through the synergy of the above components, the temperature calibration unit can accurately calibrate the temperature data collected by the infrared module. In actual use, the infrared temperature detection system using the infrared module can more accurately monitor the temperature changes of the battery module, effectively improving the accuracy and reliability of temperature measurement. Therefore, the infrared module of the utility model has broad application prospects and market potential in the fields of battery systems and the like.

[0060] To further improve the robustness, the infrared module adopts a dual power supply system to ensure that the system works stably and reliably. When in use, the infrared module adopts a dual power supply system to improve the robustness and stability of the system. The dual power supply system consists of two parts: the main power supply and the backup power supply. The main power supply is responsible for the power supply during normal operation, while the backup power supply is used as a backup energy source to deal with main power supply failures or emergencies. When the main power supply is normal, the system will give priority to the main power supply to ensure the normal operation and stable performance of the system. When the main power supply fails or is abnormal, the system will automatically switch to the backup power supply to ensure the continuous operation of the system. This dual power supply system design effectively improves the robustness and reliability of the infrared temperature detection system, ensures that the system can work stably under various conditions, and further ensures the accuracy and reliability of battery module temperature monitoring. Therefore, the dual power supply system design of the infrared temperature detection system makes the system more suitable for various complex environments and application scenarios, improves the stability and reliability of the system, and provides reliable protection for battery module temperature monitoring.

[0061] In order to further improve the accuracy and stability of temperature measurement and ensure the accuracy of monitoring data, the infrared module is equipped with a temperature compensation function, which is used to compensate the output of the infrared module according to the change of ambient temperature. When in use, the temperature compensation function equipped with the infrared module plays a vital role. This function can perform real-time temperature compensation on the output of the infrared module, i.e., the infrared sensor, according to the change of ambient temperature, thereby improving the accuracy and stability of temperature measurement and ensuring the accuracy of monitoring data. Changes in ambient temperature may affect the measurement results of the infrared sensor, resulting in inaccurate temperature monitoring data. In order to solve this problem, the infrared module in the utility model is equipped with a temperature compensation function. When the ambient temperature changes, the temperature compensation function will automatically adjust the output of the infrared sensor to eliminate the influence of temperature changes on the measurement results, ensuring the accuracy and stability of the measurement data. Through the application of the temperature compensation function, the infrared temperature detection system can maintain high-precision temperature monitoring under different environmental conditions, and can provide reliable temperature measurement results whether in high temperature environment or low temperature environment. Such a design makes the system more suitable for various practical application scenarios, providing users with more reliable and accurate temperature monitoring services.

[0062] In order to further reduce the data error rate and enhance the accuracy and reliability of the data, the infrared module adopts a multi-level verification mechanism, and multiple infrared modules are used to measure the same area multiple times. When in use, the multi-level verification mechanism adopted by the infrared module plays a key role, further reducing the data error rate and enhancing the accuracy and reliability of the data. The multi-level verification mechanism uses multiple infrared modules, i.e., infrared sensors, to measure the same area multiple times, and compare and verify the measurement results of different sensors. This design effectively reduces the risk of inaccurate data caused by single sensor error or failure. When performing temperature monitoring, multiple infrared sensors measure the same area at the same time, and then compare and integrate their respective measurement results to obtain more accurate and reliable temperature data. Through the multi-level verification mechanism, the infrared temperature detection system can better cope with the challenges of various complex environmental conditions in practical applications, and provide more accurate and reliable temperature monitoring services. This design not only improves the accuracy of the data, but also enhances the stability and reliability of the system, allowing users to use the system for temperature monitoring more confidently, effectively reducing the risks and losses caused by data errors.

[0063] In order to further improve safety and stability and reduce potential risks of failure, the infrared module has automatic fault detection and alarm functions, which can send alarms to the external system in time when abnormal conditions are found. When in use, the automatic fault detection and alarm functions of the infrared module play a key role, further improving the safety and stability of the system and reducing potential risks of failure. The automatic fault detection function can promptly detect possible faults or abnormal conditions of the infrared module, such as sensor failure, connection failure, etc. Once an abnormality is detected, the infrared module will immediately trigger the alarm system and send an alarm signal to the external system to alert the operator or system maintenance personnel and take corresponding countermeasures. Such a design can issue an alarm in time when a fault occurs, so that the operator can respond quickly to prevent the fault from further expanding and ensure the normal operation of the system. Through the automatic fault detection and alarm functions, the infrared temperature detection system has higher safety and reliability in practical applications. It can effectively reduce the risk of production accidents or equipment damage caused by equipment failures and ensure the smooth progress of the production process. At the same time, timely fault alarms also help improve the maintenance efficiency and timeliness of the system, further reduce the system maintenance and operation costs, and improve the overall economic benefits. If the infrared module detects abnormal temperature or the infrared module has a failure mode, the MCU unit will start the DO control function, prompt the alarm unit to work, and issue an alarm (such as a warning light, alarm bell, etc.) for real-time maintenance. 1) When the four-corner infrared module detects that the temperature in this area is abnormal, it will enable the adjacent four-corner infrared module to perform two checks. If the temperature in the area is abnormal, it means that the battery module has a risk of thermal runaway or overtemperature, and the MCU unit will start the alarm unit; if the temperature in the area is normal, it means that the infrared module has a risk of failure, and the MCU unit will also start the alarm unit. At the same time, the display and control unit will display and locate the cause of the fault for real-time maintenance. 2) When the central infrared module detects that the temperature in this area is abnormal, it will enable the four-corner infrared module to perform four checks. If the temperature in the corresponding area is abnormal, it means that the battery module has a risk of thermal runaway or overtemperature, and the MCU unit will start the alarm unit; if the temperature in the area is normal, it means that the infrared module has a risk of failure, and the MCU unit will also start the alarm unit. At the same time, the display and control unit will display and locate the cause of the fault for real-time maintenance.

[0064] The utility model also provides a battery pack, comprising a battery module and the above infrared module.

[0078] Therefore, the infrared temperature detection system and infrared module provided by the utility model have broad market prospects and economic benefits in practical applications, and can make important contributions to the technological development and industrial progress in related fields.

[0079] The above embodiments are described by taking the infrared module sensor with a five-point layout as an example. Figure 3The figure shows a schematic diagram of optional points for the multi-point layout of the infrared module of the infrared temperature detection system provided by the utility model. The optional points for the multi-point layout include: A01 first position, A02 second position, A03 third position and A04 fourth position distributed at the four corner vertices of the battery module. It can be understood that the lower end surface corresponding to the upper end surface is also provided with four corner vertices, which can also be used for the multi-point layout of the infrared module. In the embodiment of the utility model, there is no specific restriction on the selection of the four corner vertices, which can be the four corners of the upper end surface, the four corners of the lower end surface, or any four corners of the four corners of the upper end surface and the four corners of the lower end surface. The fifth position of the center position A05, it can be understood that there are two optional positions of the fifth position A05, which are the center position of the upper end face and the center position of the lower end face, respectively. The sixth position A06 represents the edge position of the upper end face or the lower end face when the infrared module is embedded. It can be understood that there are eight installation positions of the upper and lower end face edges indicated by the sixth position A06, the seventh position A07 represents the vertical edge position when the side end face infrared module is embedded, it can be understood that there are eight installation positions of the side edge indicated by the seventh position A07, and the eighth position A08 represents the end face position when the side end face infrared module is embedded, it can be understood that there are four installation positions of the side end face indicated by the eighth position A08. In other embodiments, the infrared module sensor can also adopt other layout methods to meet different monitoring needs and application scenarios. In addition to the five-point layout, it can also be considered to use more or fewer infrared module sensors to adapt to battery modules of different sizes, shapes or specific areas, and set them at the installation positions indicated by A01 to A08 above according to design needs. For example, for larger battery modules, the number of sensors can be increased and a denser layout can be adopted to ensure more comprehensive and accurate monitoring of the temperature distribution of the battery module, such as a seven-point layout or a nine-point layout. In other multi-point layouts, the infrared module is not limited to the four corners and the center of the battery module, but can also be set on the opposite sides, such as Figure 3The positions indicated by A06 to A08, for example, in the case of a seven-point layout, two points are set at the eighth position of A08 on the opposite sides. For smaller battery modules, the number of sensors can be reduced or a sparse layout can be adopted, such as a four-point layout set at four A07 seventh positions, etc., to save costs and meet basic monitoring needs. In addition, a customized sensor layout scheme can be designed according to the special structure of the battery module or the requirements of the working environment. For example, in areas where there are local hot spots or large temperature changes in the battery module, the density of sensors can be increased and these areas can be monitored intensively to detect temperature anomalies in time and take corresponding measures. Therefore, when selecting the layout of the infrared module sensor, it is necessary to comprehensively consider factors such as the characteristics of the battery module, monitoring requirements, cost considerations, and application environment to ensure that the system can effectively realize the temperature monitoring function. All of the above variations are within the scope of protection of the utility model.

[0080] In addition, according to the specific application requirements and the size, shape and layout of the battery module, the number and position of the infrared module sensors can be adjusted to achieve more accurate and comprehensive temperature monitoring, and the setting position of the infrared module is not limited to the position described in the above embodiment. For example, for a battery module of larger size, the number of infrared module sensors can be increased as needed, multiple infrared modules can be set at different positions of the end face, or multiple infrared modules can be set at the same position and the measurement direction of the infrared module can be directed to different directions, so that each area can be monitored more carefully, thereby more accurately understanding the temperature distribution of the entire battery module. On the contrary, for a battery module of smaller size, the number of infrared module sensors can be reduced to reduce cost and complexity, while still ensuring basic temperature monitoring functions. Therefore, in practical applications, the number and position of infrared module sensors can be flexibly adjusted according to specific circumstances to meet the needs of different scenarios.

[0081] Figures 1 to 3In the embodiments, the infrared module is described as a wide-angle infrared thermal imager. In other embodiments, the infrared module sensor may also be other types of infrared sensors, such as an infrared array sensor or a single-point infrared sensor. These infrared sensors can be selected and configured according to actual needs and application scenarios. You can choose to set all of them as wide-angle infrared thermal imagers, or you can set wide-angle infrared thermal imagers and other types of infrared sensors as needed. For larger battery modules or situations where more comprehensive monitoring is required, you can choose to use an infrared array sensor. The sensor can cover a wider range of areas and has a higher spatial resolution, which can achieve more detailed and comprehensive monitoring of the battery module temperature. For smaller battery modules or more cost-sensitive application scenarios, a single-point infrared sensor may be a more appropriate choice. The sensor has a simple structure and low cost, and is suitable for temperature monitoring of a single area or a specific location. Therefore, in practical applications, the appropriate type of infrared sensor can be selected according to the size, shape, layout and monitoring requirements of the battery module to achieve the best temperature monitoring effect. All of the above variations belong to the protection scope of the utility model.

[0082] Figures 1 to 3 In the embodiments, the embedded installation mode of the infrared module is used as an example for explanation. This installation mode enables the infrared module to be installed in the internal corners of the battery module, the structure where each surface is connected, and each surface, so as to save space to the greatest extent and adapt to the shape of the battery module. According to the position indicated by the reference numerals, those skilled in the art can use the structure in the prior art to complete the installation, and the utility model will not repeat it. This design can not only ensure that the infrared module is closely integrated with the battery module, but also effectively protect the infrared module from interference from the external environment, thereby improving the stability and reliability of the system. In other embodiments, the infrared module can also be installed on or near the surface of the battery module to adapt to different application scenarios and requirements. For example, the infrared module can be installed on the outer shell surface of the battery module, or fixed to the side or bottom of the battery module by an additional bracket. This installation mode can simplify the installation and maintenance process of the system, and can be flexibly adjusted and arranged according to specific application requirements, thereby improving the customizability and applicability of the system.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
