Battery Thermal Runaway – in general, thermal runaway can be attributed to 3 main types of abuse conditions; mechanical, electrical and thermal. The likelihood of each of these potential risks varies depending on chemistry, design and operating conditions, with the likelihood of failure generally becoming higher with battery aging.
Understanding thermal runaway is crucial, not just for battery manufacturers but also for end-users, ensuring safety in various applications, from smartphones to electric vehicles. At its core, thermal runaway is a chain reaction within a battery that leads to rapid temperature and pressure increase.
Detecting thermal runaway in electric vehicle batteries to protect against fire and explosion risks. The system uses pressure sensors inside battery cells to detect swelling indicative of thermal runaway. This early warning system can detect thermal runaway before it reaches the point of fire or explosion.
Identifying the trigger temperature for thermal runaway is complex, as it varies based on battery composition and design. Generally, lithium-ion batteries become vulnerable to thermal runaway at temperatures above 80°C (176°F). Once this threshold is crossed, the risk of chemical reactions leading to thermal runaway increases significantly.
To mitigate the risks of thermal runaway, manufacturers must take several precautions: Battery Management Systems (BMS): These systems monitor the battery’s state, including its charge level, temperature, and health, to prevent conditions that could lead to thermal runaway.
The system uses pressure sensors inside battery cells to detect swelling indicative of thermal runaway. This early warning system can detect thermal runaway before it reaches the point of fire or explosion. A battery design for mitigating thermal runaway in electric vehicle batteries, improving safety.
