[0002] New energy batteries refer to devices that can directly convert new energy in the form of chemical energy, solar energy, wind energy, hydropower, etc. into electrical energy. The working principle of new energy batteries is usually based on chemical reactions, photovoltaic effects or other physical principles, and converts new energy into electrical energy through electrochemical reactions. New energy batteries will generate a lot of heat when working. If the heat cannot be dissipated in time, the battery temperature will rise, which will affect the battery's performance, life and even safety. In a high temperature environment, the chemical reaction inside the battery will accelerate, which may lead to serious consequences such as thermal runaway of the battery, evaporation of the electrolyte, melting of the diaphragm, and ultimately cause safety hazards such as battery short circuit and explosion. Therefore, a good heat dissipation system is the key to reducing battery temperature and avoiding thermal runaway caused by overheating;

[0003] Therefore, new energy batteries need to be cooled by heat dissipation devices during actual use. The heat dissipation devices need to be evaluated before use and before they are put into use to understand the heat dissipation effect and status of the heat dissipation devices. Therefore, an evaluation system will be used to evaluate them.

[0112] Through the above process, the accuracy of heat sink installation is ensured: by extracting heat sink installation information, including heat sink production date, installation location information and connection tightness, the installation quality of the heat sink can be comprehensively evaluated.

[0113] The process of obtaining the installation position information can accurately identify the installation position deviation of the heat sink by comparing the real-time tag position information with the preset tag standard position, thereby ensuring the correct alignment between the heat sink and the battery.

[0114] The evaluation of the tightness of the connection ensures effective contact between the heat sink and the battery cooling surface, thereby improving the heat dissipation efficiency.

[0115] Improve cooling system compatibility: When multiple cooling devices are tested, batch consistency of cooling devices can be evaluated by calculating the pairwise differences between the production dates of the cooling devices.

[0116] This helps ensure that cooling devices from different batches but with similar performance can be used compatible, thus avoiding fluctuations in cooling performance due to batch differences.

[0117] Prevent potential safety hazards: Accurate installation position information and connection tightness assessment can help to promptly identify potential problems during the installation of the heat sink, such as excessive position deviation or loose connection.

[0128] The process of obtaining the ambient temperature parameter is as follows: continuously collecting at least m ambient temperature information, collecting the difference between the m ambient temperature information in chronological order, obtaining multiple temperature differences, extracting the number of times the temperature difference is greater than a preset value, and obtaining the ambient temperature parameter;

[0129] The process of obtaining the environmental humidity parameter is as follows: continuously collecting environmental humidity information at least m times, calculating the average of the m times of humidity information, and obtaining the environmental humidity parameter;

[0136] A suitable humidity environment helps maintain stable performance of the heat dissipation device and battery, and prevents performance degradation caused by excessively high or low humidity.

[0137] Improve the accuracy of evaluation results;

[0138] Dust concentration monitoring: Dust concentration is one of the important factors affecting the performance of heat dissipation devices.

[0139] By monitoring the ambient dust concentration, the impact of dust on the heat dissipation device and battery can be discovered and controlled in a timely manner to ensure the accuracy of the evaluation results.

[0140] Wind force assessment: The wind force directly affects the heat dissipation effect of the heat dissipation device.

[0141] By continuously collecting wind force information and calculating the number of times greater than or less than a preset value, the wind conditions in the test environment can be fully evaluated to ensure that the evaluation results can truly reflect the performance of the heat dissipation device in actual use.

[0142] Environmental adaptability: By conducting tests under different environmental conditions, we can understand the performance of the cooling device in different environments.

[0143] This helps optimize the design of the heat sink, improve its environmental adaptability, and ensure stable heat dissipation under various environmental conditions.

[0144] Performance improvement: Based on the evaluation results, targeted improvements and optimizations can be made to the heat dissipation device.

[0145] For example, in high temperature, high humidity or high dust environments, measures such as strengthening heat dissipation, improving sealing or adding dust prevention measures can be taken to improve the performance and stability of the heat dissipation device.

[0146] Automated evaluation: The above evaluation process adopts the method of automated data collection and processing, which can greatly improve the evaluation efficiency.

[0147] This helps reduce evaluation costs and time and improves the efficiency and accuracy of evaluation work.

[0148] Real-time feedback: By real-time monitoring and evaluation of test environment information, abnormal situations in the evaluation process can be discovered in time.

[0149] This helps to adjust the evaluation plan or take remedial measures in a timely manner to ensure the smooth progress of the evaluation work.

[0150] In summary, the specific process of obtaining the above environmental evaluation information has many benefits in the evaluation process of the heat dissipation device of new energy batteries. It not only helps to ensure the consistency of the test environment and improve the accuracy of the evaluation results, but also optimizes the design of the heat dissipation device and reduces the evaluation cost and time. This is of great significance to promoting the development and application of new energy battery technology.

[0151] The acquisition process of the test warning information is as follows: extracting the acquired image information during the test process, the image information during the test process is the infrared image information of the new energy battery heat dissipation device collected by the infrared image acquisition device, analyzing the infrared image information, and recording the change speed from shallow to deep during the change of the infrared image information. When the change speed is greater than a preset value, the test warning information is generated;

[0152] When there is an area in the infrared image information where the color depth is greater than the preset value, a test warning message is generated;

[0153] The heat dissipation effect can be monitored in real time through the above process, and the temperature distribution and changes of the new energy battery heat dissipation device can be monitored in real time through the infrared image acquisition device.

[0155] Precise positioning: Infrared imaging information can clearly display the temperature gradient on the surface of the heat sink, helping technicians quickly locate overheating areas.

[0156] This helps to detect and address potential thermal issues before they become more serious.

[0157] Safety hazards are prevented. When there is an area in the infrared image information with a color depth greater than a preset value, it indicates that the temperature in the area is too high, which may cause safety hazards.

[0158] By generating test warning information, the system can promptly remind operators to take measures to reduce the temperature, thereby preventing safety accidents.

This helps technicians to optimize the design of the heat sink in a targeted manner and improve its performance.
