AI Technical Summary

Technical Problem

Conventional fire extinguishing systems for electric vehicle batteries are limited by insufficient fire extinguishing agent storage, inefficient distribution, and inability to intelligently target the ignition source, leading to waste and ineffective fire control.

Method used

A smart fire suppression system with high-sensitivity smoke detectors, thermal sensors, and a control system that maps fire coordinates and evaluates impact levels to direct fire extinguishing nozzles to the ignition source, using a variable flow path mechanism and multiple extinguisher canisters to efficiently extinguish fires.

Benefits of technology

The system intelligently targets the ignition source, reducing extinguishing agent waste and enhancing fire control efficiency by concentrating efforts on the main area of the fire.
