Structural Design and Test of Mining Explosion-Proof Lithium-Ion Battery Power Box
Mining underground transportation equipment has been developing towards lithium-ion,but the safety of lithium-ion batteries seriously limits its popularization and application.Through the thermal runaway test of lithium-ion batteries,the maximum gas production rate of 230 Ah lithium iron phosphate battery is 17.3 L/s.A bursting pressure relief device is developed by using the fire stopper made of multi-layer wire mesh.30 mm diameter bursting pressure relief device can have a permeability rate of 9.495 Us under 50 kPa pressure,i.e.,the use of two bursting pressure relief devices can meet the requirements of one battery.Battery thermal runaway pressure relief needs.This device not only has the function of pressure relief,but also meets the requirements of explosion isolation and waterproofing in underground explosive and humid environments.The explosion-proof lithium-ion battery power supply box developed based on this explosion-proof pressure relief device has passed the test of explosion-proof national standard and coal mine standard.
