Perfluorohexanone fire suppression device for electric bus lithium-ion power battery box

Electric bus lithium-ion power battery (box) fire prevention and control product (fire suppression device). When the battery in the power battery box experiences thermal runaway, the fire suppression device is activated immediately and the fire suppressor is delivered to the battery box through pipelines and nozzles.

The fire suppression device is matched with the fire prevention and control product developed by our company (carbon monoxide and temperature-sensing composite fire detector). It has early warning, fault alarm (open circuit/short circuit/insufficient air pressure/detector failure, etc.) self-checking and functions. It can promptly detect abnormalities in the temperature and carbon monoxide data in the battery box, and specify the battery box to quickly spray inhibitors. Advanced integrated computer control, with functions such as data storage, real-time data upload and sharing, to facilitate subsequent investigation of causes. Through the CAN protocol, a single line can be used to control the entire vehicle battery box. It has the characteristics of fewer connecting lines, easy installation, low power consumption, infinite expansion, stable and reliable system, and fast startup speed. The system has its own power supply to ensure that the system can work normally within 72 hours of the vehicle being out of service. The system comes with a Chinese display screen that displays system status and related fault information in real time. The system can freely adjust specific parameters according to the personalized requirements of the bus.

Structure diagram and technical parameters
