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.

Nitrogen Fire Protection Device for Preventing EV Li-ion Battery Thermal Runaway
The nitrogen fire protection system works by detecting and controlling small fires before they have a chance to spread, preventing thermal runaway in its early stages. Nitrogen protection is applied to the safety protection of lithium-ion batteries to prevent self-ignited fires and fire development, thus improve the safety performance of EV Li-ion batteries during driving, charging operation or simple parking. The device is also widely used in energy storage system and lithium-ion battery based UPS applications.
Custom Nitrogen Fire Protection System to Prevent Thermal Runaway and its Propagation in Lithium-ion Battery
In order to prevent lithium-ion battery fires from occurring, and effectively control thermal runaway, Guchen Electronics has developed an exclusive and proactive solution in electric vehicle battery safety protection. The unique solution is called “Nitrogen Fire Protection Device”.
The battery protection system can prevent thermal runaway of lithium batteries before it even happens. The novel nitrogen protection system has been designed as an integrated solution for all types of lithium batteries. This system consists of two major components: 1) Nitrogen Generation System – When the pressure sensor detects that the gas tank pressure is lower than a certain pressure value during 24-hour pressure monitoring, the nitrogen generation module starts to work, to generate N2 gas from compressed air compressed by vehicle air compressor. 2) Control module – contains master controller and slave controller. The main controller exchanges data with the vehicle BMS and is electrically connected to the battery box. It is used to detect the nitrogen pressure threshold input to the battery box and limit the fire conditions in the battery box in real time.
Features and Benefits of The Latest Generation Nitrogen Fire Protection Device
◆ Easier and affordable installation, require very little maintenance
Nitrogen fire protection systems can be installed quickly and easily, making them ideal for all EV manufacturers.
◆ Data interaction with vehicle BMS
Battery Management System (BMS) – Monitors the state of charge (SoC), voltage and temperature of individual cells within each battery pack, detecting fire and providing information on the current state of battery cells, while also giving early warning of any potential problems that may occur during driving, charging or parking.
◆ Stop the cascading effect of thermal runaway
Thermal runaway occurs when a battery becomes overheated and self-ignited heat, which in turn causes it to overheat even more. This can lead to a catastrophic event known as thermal run away, which can result in an explosion or fire. The latest generation of nitrogen fire protection device is designed to prevent thermal runaway by releasing a controlled amount of nitrogen gas into the battery enclosure, creating a fire-retardant atmosphere. The gas displaces oxygen from the enclosure and decreases the oxygen level available to sustain combustion, thus preventing thermal runaway.
◆ It is not a fire suppression system
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 the fire from further expanding, prevents thermal runaway chain reactions and fire explosions, rather than extinguishing the fire.
◆ Modular design, customers can choose according to specific needs
◆ IP68 & 360H anti-corrosion
◆ 24H real-time monitoring, optional cloud platform service
Monitoring and displaying the battery status on real time basis
◆ Provide a full range of customized solutions
