The nitrogen fire protection system pioneered by Guchen Team can effectively prevent thermal runaway and thermal runaway propagation in lith
EV lithium-ion batteries are increasingly used in electric vehicles and energy storage systems, which are exposed to high temperatures during charging and discharging. In addition, the fire is also a major safety hazard for EV lithium-ion battery safety. Therefore, it is essential to take measures against thermal runaway in order to prevent the occurrence of an accident caused by fire.
During charging and discharging, hot spots may occur on the surface of the battery or inside the battery due to internal short circuits or failures. These hot spots can trigger internal explosions or fires that can cause serious damage to people or property. Therefore, it is necessary to prevent thermal runaway in EV lithium-ion batteries during charging and discharging.
The most commonly used method for preventing thermal runaway in EV lithium-ion batteries has been through the use of metal halide fire extinguishers or water-based fire extinguishers; however, these methods have several shortcomings such as low efficiency, high cost and poor reliability. Therefore, there is a need for more effective methods for preventing thermal runaway in EV lithium-ion batteries.
Nitrogen fire protection system is regarded as the most efficient and reliable thermal runaway risk prevention method in EV lithium-ion battery safety; it can effectively suppress internal explosion caused by heat.
