The match product information of FireLess 0.3 Fixed Aerosol Fire Extinguishing Systems For Battary Packs

FireLess early warning and control device for power battery packs is a special fire protection product which is developed to solve the fire caused by the thermal runaway of new energy vehicles’ power battery. The device is an integrated design with multiple functions including active detection, data analysis, control and management, which includes high sensitivity temperature sensor, gas sensor, smoke sensor, flame sensor. It was installed in the battery pack of the power battery and connected with the automatic fire extinguishing device and the BMS management system, detecting the gas, heat, smoke and open fire produced in the early stage of the fire which are caused by excessive charging and discharging, external and short circuit and so on in the battery box. Through the intelligent system analysis of the thermal runway phase of battery, the device will make a automatic intervention control. The device have many advantages, such as small volume, easy to install and layout, excellent adaptability, multiple detection, scientific and advanced data analysis model, accurate and rapid response control, intelligent dynamic management, etc.

Thermal runaway warning of power battery pack and fire extinguishing technology

Thermal runaway warning of power battery pack and fire extinguishing technology is aim at solving the fires of EVs that is caused by the thermal runaway problem. And the advance technology of FireLess is very effective to control the power battery packs in early stage and save the property.

The operation principle of system

When the power battery fails and begins to vent pressure and heat, the detector can detect abnormal changes, and send out early warning signals to the driver through the CAN bus or wire harness for the potential stage, smoke stage, high temperature stage and open fire stage of the fire, which is to realize the classified early warning and the control of fire-extinguishing device. The system can intelligently judge and automatically initiate the fire extinguishing device to prevent the deterioration of the fire situation, and can also activate the fire extinguishing device manually during the emergency. The fire extinguishing device controls the fire in seconds through its high-efficiency fire extinguishing agent and maximizes the safety of the battery pack.
