AI Technical Summary
Technical Problem
Existing technology cannot promptly determine whether a lithium-ion battery in a new energy vehicle will catch fire after being hit, resulting in the inability to provide early warning of fires and causing losses.
Method used
Design a pump-suction type composite fire detection device for lithium-ion battery boxes. The device actively draws in gas from the lithium-ion battery box using a gas pump, detects the gas composition using a composite detector, determines whether a fire will occur, and alerts the fire protection system to prepare fire-fighting gas before a fire is detected.
Benefits of technology
It enables early prediction of lithium-ion battery box fires, thus avoiding losses caused by fires.

Abstract
This application discloses a pump-suction type composite fire detection device for lithium-ion battery boxes, relating to the field of battery fire protection. The first end of a three-way valve is connected to an air inlet pipe, the second end to a fire protection pipe, and the third end to an air pump input via a delivery pipe. A composite detector is installed at the air pump output, electrically connected to both the air pump and the three-way valve. The composite detector controls the three-way valve to connect the air inlet pipe to the air pump input and controls the air pump to draw in sample gas from the lithium-ion battery box. The composite detector also detects the gas composition in the sample gas and determines whether a fire will occur based on the composition. Furthermore, when a fire is detected, the composite detector controls the three-way valve to connect the fire protection pipe to the air pump input and controls the air pump to draw in fire protection gas. This device provides early warning of fires.
