AI Technical Summary

Technical Problem

In the chassis dynamometer testing environment, overheating of the battery in electric vehicles may lead to thermal runaway, posing a serious safety hazard. Existing technologies are unable to effectively prevent and respond to such abnormal situations.

Method used

A fire response system is adopted, including deployable fire extinguisher cylinders, electric winches, status measuring devices, and controllers. By monitoring the status of electric vehicles in real time, the deployable fire extinguisher cylinders are deployed and fire extinguishing water is supplied to them when preset conditions are met, immersing the electric vehicles in water to prevent thermal runaway.

Benefits of technology

It effectively protects the safety of testing equipment and personnel, prevents damage and accidents to electric vehicles caused by thermal runaway, and enables rapid response and prevention of potential dangers.

Abstract

This disclosure relates to a fire response system and method for electric vehicles in a chassis dynamometer testing environment. The fire response system includes a chassis dynamometer, a main roller, a deployable fire extinguisher cartridge, an electric winch, sensors, and a controller. The chassis dynamometer provides a predetermined test space for a test vehicle located in a test area. The main roller is positioned on one side of the test area, and the deployable fire extinguisher cartridge is connected to the main roller via an unwinding line to be wound around or unwound from the main roller. The electric winch is positioned on the other side of the test area and is connected to the deployable fire extinguisher cartridge via a winding line. Sensors collect predetermined information from the test vehicle. Under predetermined conditions, the controller deploys the deployable fire extinguisher cartridge under the test vehicle and supplies extinguishing water to immerse the test vehicle in the extinguishing water.
