In recent years, with the continuous expansion of battery applications, safety concerns have become increasingly prominent. As one of the most dangerous faults during battery operation, thermal runaway, when it occurs, can lead to severe battery damage and even trigger safety incidents. Therefore, how to effectively monitor and provide early warning for thermal runaway has become a critical issue in the industry.
Thermal runaway is a cumulative self-accelerating reaction that occurs during the constant voltage charging process of batteries. In this state, the internal temperature of the battery and the float charging current interact with each other, forming a vicious cycle that eventually leads to battery expansion, deformation, or even failure. The main causes include an increase in heat generation during the oxygen cycle and poor heat dissipation, which leads to a rapid temperature rise and further accelerates oxygen evolution and heat release.
Traditional valve-regulated lead-acid (VRLA) batteries, which use constant voltage charging, are particularly prone to thermal runaway when the float charging current increases rapidly and exceeds safe limits, leading to irreversible damage.
To address the issue of thermal runaway, the DFUN Battery Monitoring System (BMS) offers a comprehensive and efficient solution. By real-time monitoring of the battery's negative electrode temperature, float charging current, and integrating critical data such as ambient temperature, DFUN BMS can precisely analyze early signs of thermal runaway and provide intelligent early warnings.
