During the continuous decrease of the storage battery performance, due to external forces or the reasons of the storage battery itself, it is easy to cause a storage battery fire. A storage battery fire is an abnormal reaction that occurs during the charging and discharging process of the storage battery, resulting in an increase in temperature, electrolyte leakage, or short circuit, etc., and then causing a fire accident. Therefore, many storage battery safety control systems have been designed in the prior art to prevent storage battery fires;
[0003] However, when the prior art prevents storage battery fires, it is unable to comprehensively evaluate the operating electrical signal data and operating temperature data of the storage battery, resulting in an inability to accurately analyze the abnormal degree of the storage battery operation.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use.
[0044] Embodiment 1
[0045] To solve the technical problems raised in the background art: when the prior art prevents battery fires, it is unable to comprehensively evaluate the battery operation electrical signal data and operation temperature data, resulting in the inability to accurately analyze the degree of battery operation abnormality. Furthermore, it is unable to predict the remaining life of the battery through the accurately obtained change rate of the battery operation abnormality degree, reducing the accuracy of the remaining life prediction of the battery and thus reducing the ability to master the danger of the battery; the present invention provides a preferred embodiment: as Figure 1 - Figure 2 shown, a battery safety control method based on remote monitoring, which includes the following specific steps:
[0046] S1. The data acquisition module acquires the operation data of the battery during the operation of the battery, and simultaneously obtains the operation temperature data of the battery;
[0047] In this embodiment, the specific steps for the data acquisition module to acquire the operation data of the battery during the operation of the battery and simultaneously obtain the operation temperature data of the battery are as follows:

[0051] Importing the current and voltage data during the operation of the battery acquired into the operation abnormality analysis model for analysis is a reasonable and necessary practice;
[0052] Current and voltage are key parameters for measuring the health and performance of a battery. Under normal operating conditions, a battery will have a stable current-voltage curve. Any abnormal fluctuations deviating from this curve may indicate potential problems with the battery. By real-time monitoring of current and voltage data, an operation anomaly analysis model can detect early fault signs of the battery in a timely manner, such as overcharging, over-discharging, internal short circuit, etc. This information is crucial for implementing preventive maintenance and can avoid battery performance degradation and even safety accidents.
[0053] As a power supply component for many critical systems, the reliability of a battery directly affects the stability of the entire system. For example, in fields such as data centers and communication base stations, battery failures may lead to service interruptions. Through the anomaly analysis model, problems can be identified in advance and measures can be taken to improve the overall reliability of the system.
[0054] Timely analysis of current and voltage data can reduce safety risks caused by battery failures and at the same time reduce economic losses caused by emergency repairs or battery replacements. Therefore, from the perspectives of safety, economy, and maintenance, it is very reasonable to import the current and voltage data of the battery into the operation anomaly analysis model for anomaly analysis.

Divide the monitoring period evenly into several monitoring time segments, where the duration of the monitoring time segment is from 1 s to 3 s. Obtain the average voltage change data curve of each monitoring time segment and import it into the voltage anomaly value calculation formula to calculate the voltage anomaly value. The voltage anomaly value calculation formula is:
[0057] where a is the voltage difference amplitude ratio coefficient, N is the number of monitoring time segments in the monitoring period, Vi is the average voltage value of the i-th monitoring time segment, and Vm is the voltage standard value of the i-th monitoring time segment.

Among them, the temperature anomaly analysis value calculation formula is: where m is the number of monitoring points, Tj is the temperature value of the jth monitoring point, Tjm is the median of the temperature safety range of the jth monitoring point, Tjmax is the maximum value of the temperature safety range of the jth monitoring point, and Tjmin is the minimum value of the temperature safety range of the jth monitoring point;
[0063] S32. Substitute the calculated operating anomaly analysis value and temperature anomaly analysis value within the monitoring period into the storage battery anomaly degree analysis value calculation formula to calculate the storage battery anomaly degree analysis value. Among them, the storage battery anomaly degree analysis value calculation formula is:
[0064] XZ = (λXV + (1 - λ)XI + 1) × exp(XT), where exp() is the exponential power of the natural constant e;
[0065] S4. Import the analyzed anomaly degree of the storage battery and the service time of the storage battery into the storage battery remaining life prediction model to predict the remaining life of the storage battery;
