Battery Nail Penetration Test Chamber

The battery nail tester penetrates the battery with a steel nail to test the safety performance of the battery. The battery is qualified if it does not catch fire or explode. The nail penetration test is carried out at a temperature of 20°C±5°C. The sample cell has a thermonuclear contact on the largest surface. Place the battery on the fumigation cabinet. Use a stainless steel nail with a diameter of 2-8mm to penetrate the center of the most protruding surface of the battery at a speed of 10mm/s-40mm/s and keep it for 5s.
