Li-ion Battery Fire Protection System

The most effective lithium-ion battery fire protection system is using nitrogen gas as protection to lower the oxygen level in the power battery box. By this method, If the battery box catches fire due to external factors, the nitrogen stored in the gas tank provides protection, isolates oxygen in the air, prevents thermal runaway, and prevents explosion.
