This battery explosion-proof box is used to prevent battery explosion or combustion from causing unnecessary harm to test personnel during overcharge, over-discharge or other tests. The entire body is made of steel, with a strong texture and good explosion-proof effect.

Technical Parameters

Temperature fluctuation	≤±0.5℃
Temperature deviation	≤±1.5℃
Temperature uniformity	≤1.5℃
Heating rate	0℃~85℃, full range average 3℃/min non-linear (no load)
Cooling rate	85℃~0℃, full range average 1℃/min non-linear (no load)
Structural requirements	The equipment is integrally formed. The explosion-proof strength of the box meets the explosion strength of a module consisting of two 325Ah battery cells connected in series. 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.
Noise index	≤70dB (measured at 1m and 1.5m from the device in the forward direction)
Box bottom	Equipped with 4 universal wheels and 4 fixed feet, easy to move and stable
Exhaust system	Each chamber can be controlled independently. The smoke generated by the test sample can be automatically detected and alarmed and the smoke can be discharged through the pipe. The discharge volume needs to be provided.
Video surveillance	The test area is equipped with a high-definition video surveillance system and can be remotely controlled; Color video; Pixels ≥ 5 million pixels; Video acquisition resolution: PAL: D1 (704x576) / CIF (352x288) / QCIF (176x144), and multimedia format (320x240); Horizontal clarity: 700TVL; Recording and playback speed: 25 frames/second per video channel (PAL); Video memory adds a mobile hard disk, and the video surveillance system is compatible with the mobile hard disk for storage to ensure data accuracy. (If the surveillance system needs to be set up in an explosion area, the surveillance system needs to have explosion-proof function, and the camera can still monitor clear images after the explosion, which will not affect the next use) (optional)
Other functions	The observation window is made of explosion-proof glass and explosion-proof film, with a size of 300 * 300mm.
	Equipped with fire extinguishing device, automatic and manual fire extinguishing (optional)
	Install lighting system
Equipment inner box	Made of 2mm SUS304 stainless steel + 3mm cold-rolled steel plate, with external welded reinforcement ribs to ensure the strength of the inner box. Prevent the impact of battery explosion from damaging the box. Adopts TIG continuous welding; has acid-proof, explosion-proof and corrosion-proof functions; C5 channel steel is welded on the outside of the box for reinforcement;
Strong base and frame	The base of the equipment is welded with channel steel. The frame is welded with channel steel on the base, and the whole equipment is fixed on the channel steel frame, which is strong and durable, with small vibration and low noise during operation.
Strong door frame	The door frame outer box sheet metal is reinforced by welding channel steel around the perimeter. The hinges and door locks are fixed on this channel steel. M6 high-strength bolts are used to fix the door frame to ensure the strength of the box.
