UN38.3 Test Chamber Supplier Battery Pack Explosion Test Machine

Three sets of high-strength stainless steel hinges are installed on the left and right sides of the door. A single hinge can withstand 3 tons of force in transverse stretching without breaking. Even if it is bent in the opposite direction, the two hinge pieces are completely deformed and combined into one without breaking, ensuring the fixing strength of the left side of the door.

Explosion-proof design

1) The equipment is integrally formed, and the explosion-proof strength of the box body meets the explosion strength of two 230Ah battery cells. Effective explosion-proof pressure relief design is carried out. The steel plate material is treated with rust-proof insulation and is effectively flame-retardant. Structural design drawings are provided. Explosion-proof chains are installed to prevent the box door from being opened.

2) Use 2mm thick SUS304 stainless steel inner wall + 3mm cold-rolled steel plate and 5# channel steel reinforcement. At the same time, add a pressure relief port (300*300mm). According to the finite element software analysis, under this yield pressure, it is calculated that the box + pressure relief port can withstand a force of ≥ 1.2bar under the condition of pressure relief. It meets the pressure generated by 230AH battery failure.

Explosion-proof chain

Install 2 explosion-proof chains (φ8mm) on each side of the gate (4 pieces in total) to prevent the gate from bouncing open and flying out under the impact of an explosion.
