BMS Temperature Monitoring: Ensuring Battery Safety and Performance

In a battery management system, temperature monitoring is a crucial function. Whether it’s high temperature or low temperature, it can affect the performance and lifespan of lithium batteries. Therefore, BMS temperature monitoring has become an important means to ensure the safe operation of batteries. This article will discuss the impact of temperature on lithium batteries, the necessity of BMS temperature monitoring, and related technical modules.

Impact of Temperature on Lithium Batteries

The primary purpose of BMS temperature monitoring is to prevent abnormal temperatures from damaging the battery. In low-temperature environments, although the performance of lithium batteries is superior to traditional batteries, if the charging temperature is below 0℃, a metal lithium plating layer may form on the anode. This can cause permanent damage to the battery, not only reducing its capacity but also potentially increasing safety risks. In high-temperature environments, the chemical reaction rate of lithium batteries increases. While this may initially boost capacity and performance, long-term high-temperature usage will accelerate battery aging, reduce service life, and even cause thermal runaway, leading to severe safety hazards. Therefore, the role of BMS temperature monitoring is especially important.

Necessity of BMS Temperature Monitoring

The BMS temperature monitoring function ensures that the battery operates within a suitable temperature range by real-time monitoring of the battery’s temperature. Batteries can experience performance degradation or safety issues at excessively high or low temperatures. Through BMS temperature monitoring, temperature anomalies can be detected in time, and by adjusting the operating mode or initiating protective measures, battery damage or safety incidents can be prevented. Effective temperature management not only extends the battery’s service life but also ensures stability and reliability in various environments.

BMS Temperature Management Functions

The BMS temperature monitoring module is typically composed of multiple temperature sensors distributed throughout the battery pack, monitoring the battery’s temperature changes in real-time. The main functions of BMS temperature management are as follows:

• Accurate measurement and monitoring of battery temperature to ensure the battery always stays within a safe temperature range.
• Effective heat dissipation and ventilation. When the battery pack temperature is too high, the cooling system activates to keep the battery cool.
• Rapid heating in low temperatures. In cold environments, the heating system activates to prevent the battery from freezing or incurring low-temperature damage.
• Harmful gas treatment. Monitoring changes of gases inside the battery to ensure safe ventilation.
• Even temperature distribution. Ensuring the battery temperature across different areas is balanced to avoid local overheating or overcooling.
• Emergency shutdown protection. When temperature anomalies cannot be effectively controlled, cutting off the battery system in time to prevent further damage.
