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
We can modify the communication protocol according to customer needs, to achieve customized display solutions;
◆ Preventing condensation of battery packs in coastal areas with high humidity and certain places with wide difference between day and night temperatures.

Guchen nitrogen protection system is the only safety system currently proven to hamper the development of heat, and protect against thermal runaway in a lithium-ion battery pack. It is a perfect and techno-edge solution for actively internal fire prevention, and has been widely applied in highway buses, tourist coaches, city buses, commuter buses, autonomous driving bus, mining trucks and renewable energy storage market. We can confidently say that the nitrogen fire protection system can effectively stop unmanaged flames from causing an uncontrolled chain reaction to surrounding battery modules/cells.
The Development of Guchen Nitrogen Fire Protection System
From design simulation to actual vehicle trial production and verification, the development cycle of the power battery nitrogen protection system takes more than two years. After many rounds of improvement, it has completed the design and selection of 16 types of parts, matching and integration of 3 subsystems, optimization of 4 working mode strategies, and experienced extreme environmental (high-temperature, high-altitude) road tests, and carried out 3 rounds of trial production optimization. It passed 1,095 test verifications and finally successfully completed a stable trial operation of 150,000 kilometers.
