Fire extinguishing solution for battery swapping cabinets
I. Current Fire Safety Situation and Risk Analysis of Battery Swapping Cabinets
With the rapid development of the new energy industry, battery swapping cabinets for two-wheeled vehicles have been widely deployed across urban areas as a convenient energy replenishment solution. However, the batteries inside these cabinets operate under long-term charge–discharge cycles. Issues such as battery aging, short circuits, and overcharging can easily trigger fires. Once a fire becomes uncontrolled, it may not only cause significant economic losses but also threaten the lives of nearby personnel and lead to cascading safety incidents. Traditional fire protection methods often suffer from slow response times, low extinguishing efficiency, and the risk of secondary damage to equipment when dealing with battery swapping cabinet fires. Therefore, there is an urgent need for an efficient and safe fire suppression solution.
II. Suitability Analysis of the 10 g Thermal Aerosol (QRR0.01GW/S) Automatic Fire Suppression Device
The 10 g thermal aerosol automatic fire suppression device developed by Chenfeng Lingchuang is specifically designed to address such fire safety challenges. Featuring zero-pressure storage and a solid extinguishing agent, it eliminates the leakage risks associated with traditional liquid or gaseous fire extinguishing agents, offering a high level of safety. In terms of technical parameters, the device has a service life of up to 10 years, significantly reducing long-term maintenance costs. It supports both thermal activation and electric activation, ensuring rapid response under different operating conditions. With a wide operating temperature range from –50°C to +90°C, it can adapt to various complex climatic environments. The protected volume of ≤0.1 m³ is precisely matched to the relatively enclosed and compact internal space of battery swapping cabinets. A thermal aerosol agent charge of 10 g ±2% enables the rapid generation of fire-suppressing aerosol, quickly controlling and extinguishing fires inside the cabinet.
III. Application of the Working Principle in Battery Swapping Cabinet Fire Protection
During operation, when the internal temperature of the battery swapping cabinet reaches the activation threshold of ≥170°C, the solid extinguishing agent is heated to a high temperature and, through advanced aerosolization technology, is released as fine particles in an aerosol state. These aerosol particles rapidly disperse throughout the entire cabinet, effectively isolating oxygen, reducing temperature, and quickly suppressing and extinguishing the fire source. At the same time, the aerosol particles can help purify harmful substances generated by battery combustion, providing a relatively safe environment for subsequent inspection and maintenance personnel.
IV. Installation and Layout of the Device in Battery Swapping Cabinets
Installation Position: According to the internal structure of the battery swapping cabinet, the 10 g thermal aerosol automatic fire suppression device should be installed at the top center of the cabinet or above the battery compartment to ensure uniform distribution of aerosol particles throughout the internal space.
Installation Method: The device should be securely mounted using screws or dedicated mounting clips to ensure stability and prevent detachment caused by vibration or other external factors.
Quantity and Layout: For standard-sized battery swapping cabinets, a single 10 g thermal aerosol automatic fire suppression device is sufficient to meet protection requirements. For larger cabinets or those containing a higher number of batteries, the number of devices should be increased appropriately based on the actual space and protection needs to eliminate fire protection blind spots.

V. Routine Maintenance and Management
Regular Inspection: Establish a routine inspection system for fire suppression devices in battery swapping cabinets. Conduct monthly visual inspections to check for damage, deformation, or other abnormalities, and perform quarterly functional checks using the device’s self-diagnostic features to verify normal operation.
Documentation and Replacement: Maintain detailed records of each inspection, including inspection dates and device status. When the device reaches the end of its service life (10 years), replace it promptly to ensure continuous and effective fire protection.
Personnel Training: Provide professional training for operation and maintenance personnel responsible for battery swapping cabinets, ensuring they are familiar with the working principle, operation procedures, and maintenance requirements of the thermal aerosol automatic fire suppression device, thereby enhancing their ability to respond to emergency fire incidents.
VI. Conclusion
The 10 g thermal aerosol (QRR0.01GW/S) automatic fire suppression device manufactured by Chenfeng Lingchuang offers a reliable solution for battery swapping cabinet fire safety, thanks to its environmental friendliness, high efficiency, safety, and ease of use. Through scientifically planned installation and standardized routine maintenance, it can effectively prevent and mitigate fire incidents in battery swapping cabinets, providing strong support for the safe and stable development of the new energy industry.
