Altitude Test Chamber with Temperature Cycling System

◆The equipment starts/stops using a panel switch button and the host computer controls two methods, both of which can be realized. Customers can operate according to the actual needs of the battery pack.
◆The monitoring camera system monitors the appearance changes of the object in real time during the test, and records them in the video database for storage, which is convenient for analyzing the pressure damage events and damage methods of the battery shell material and their processes.
◆The impact protection cover box is composed of high temperature resistant, corrosion resistant (stainless steel), and flame retardant components. The reinforced design can effectively isolate the damage caused by fire and explosion during the test.
◆The setting of all control parameters, data acquisition, and video recording of the remote control monitoring system can be operated by a computer that is more than 30m away from the equipment.
◆The equipment is compatible with tests of domestic and foreign standards such as GB31241, IEC62133-2017, UL1642, and UN38.3.

Program editing is performed through the control interface. Except for power supply, start, lighting, emergency stop, and manual pressure relief, other operations only need to be completed in the control panel. Cabinet Features Inner box material SUS304 stainless steel, weld polishing. Steel plate thickness 5.0MM, the outer side of the inner box is reinforced with steel plate strips, Outer box color Galvanized sheet powder high temperature spray Pressure bearing method Internal pressure Observation window Double-layer vacuum glass; electric heating for door frame (automatic adjustment, automatically shutting off window frame heating when the temperature inside the box is high) Anti-frost and anti-condensation devices. External Interface The current, temperature and wiring ports can be reserved as required, while ensuring the sealing of the box Illumination The lighting strip is installed on the observation window of the box door. The LED light strip can illuminate the entire test space.Only light can be seen outside the box, but no light can be seen.This can avoid glare problems and solve lighting problems. Vacuum Pump A stainless steel chuck-type quick interface is welded on the side of the box, which can be used to quickly connect to the external pipeline. A solenoid valve is installed in the middle and connected to the vacuum pipeline. Within 30 minutes, the pressure reaches below -98Kpa. Manual inflation valve The manual pressure relief valve connects the inside and outside of the box to achieve pressure balance inside and outside the box, and the box door can be opened. Automatic pressure relief When the pressure holding time is reached, the pressure can be automatically released Cooling method Air Cooling Protective devices Compressor overheat protection, compressor overload protection; Compressor high and low pressure protection; Box overtemperature protection; Door closing protection; Phase sequence protection; Circulating fan protection; Heating overtemperature protection; Magnetic fluid water shortage protection; Cooling water underpressure protection; Three-color indicator alarm system; Other function alarms Supply voltage AC380V±10% 50HZ±10%
