Why do lithium batteries need temperature measurement

With the development of emerging clean energy sources such as wind energy, hydropower, and nuclear energy, energy storage technologies have also been vigorously developed. Lithium ion battery container energy storage stations are widely used in the field of power storage due to their advantages such as high energy density, high output power, long service life, environmental friendliness, and wide applicability. Although lithium-ion battery energy storage containers have the above advantages, if the lithium-ion batteries inside are subjected to thermal abuse, it is easy to cause abnormal heat accumulation inside the batteries, increase surface temperature, and trigger thermal runaway of lithium-ion batteries, leading to dangerous situations such as explosions and fires. Given the close arrangement and high energy density of lithium-ion batteries inside the lithium-ion battery energy storage container, if individual batteries experience thermal runaway, it is highly likely to cause nearby batteries to heat up, leading to the dangerous situation of thermal runaway propagation and causing a fire disaster in the entire energy storage container, resulting in huge economic losses. Se poutèt sa, a safe and reliable temperature monitoring technology for the prefabricated cabin of electrochemical energy storage stations is of great significance for the safe use and expansion of their application scope.

Koumanse, various consumer electronics, mobile power supplies, new energy vehicles, elatriye. represented by mobile phones, all use lithium battery devices. With the continuous increase in usage, manufacturers of batteries are also emerging. An menm tan, accidents such as fires and explosions in lithium battery warehouses are also frequent. Lithium batteries need to be turned over and stored in batches during the production process after formation and capacity division. During this process, lithium batteries have not yet been produced, and their state is extremely unstable, which can easily lead to internal short circuits or leakage problems, ultimately resulting in local temperature rise of lithium batteries. If not detected in time, it can cause accidents such as fires or explosions. Sepandan, in the traditional management process of lithium battery warehouses, there is a lack of monitoring and management of battery temperature. Some manufacturers use relatively ordinary fire smoke and temperature sensing devices for crude detection. Ordinary temperature sensors cannot obtain temperature information in the early stage of temperature rise, and only emit alarm information when it reaches 70 ℃ or above. Smoke sensors only emit alarm information when smoke occurs, which cannot achieve the goal of preventing fires in the early stage. Sepandan, some methods that use wireless temperature measurement, such as 433MHz, Zigbee, Lora, elatriye, due to the large number of battery storage points, will ultimately generate serious co frequency interference and temporary frequency interference, leading to communication failure of wireless monitoring equipment. The delay of the sensor points sent during time sharing is very serious, making it difficult to accurately monitor the temperature of the battery storage in real time. Se poutèt sa, it is very important to provide a temperature monitoring system technology for battery storage based on distributed fiber optic temperature measurement, which can detect the temperature changes of the stored lithium batteries and turnover lithium batteries with severe temperature rise. This can effectively reduce the occurrence of fires and explosions, detect problems in a timely manner, and ensure the safety of battery warehouses and people’s lives and property.

Koumanse, there is not much research on temperature monitoring technology specifically for electrochemical energy storage stations. The internal temperature monitoring of electrochemical energy storage stations currently in use mostly uses traditional thermocouple temperature measurement or infrared temperature measurement technology. Thermocouples have high temperature measurement accuracy and are generally reliable, but the temperature measurement area of a single thermocouple is too small. When applied in large spaces, it must be laid out point by point, and still cannot meet the requirements of multi-point temperature measurement in large spaces. Infrared temperature measurement also has the problem of small temperature measurement area and low temperature measurement accuracy, which cannot meet practical engineering needs well.

The technology used in the distributed fiber optic temperature measurement system is different from the limitations of traditional temperature measurement methods, which have a small temperature measurement area. It has a temperature measurement length of tens of kilometers and can ensure the required temperature measurement accuracy. The material itself is safe and reliable, making it more suitable for temperature monitoring in lithium-ion battery electrochemical energy storage stations.
