What kind of experimental equipment is a medium-sized comprehensive experimental module?

The medium-sized comprehensive test chamber (also known as the 82L battery comprehensive performance test chamber) can achieve coupling of various environmental factors (temperature, pressure, atmosphere, etc.) to conduct multiple types of tests on batteries (needle puncture, compression, overcharge, overdischarge, short circuit, temperature cycling, ignition, fire extinguishing), and is used for comprehensive performance testing of battery cells and small battery modules. 

What experiments can the medium-sized comprehensive experimental module be used for?

The medium-sized comprehensive experimental cabin was independently developed, designed and manufactured by Dianshi Instruments. This experimental equipment supports eight types of battery experiments, namely:

1、Battery needle-puncture test: Battery needle-puncture tests under different environmental conditions (high pressure/low pressure, high temperature/low temperature/local high temperature, oxygen-rich/oxygen-poor/protective gas). 

2、 Battery compression test: Battery compression tests under different environmental conditions (high pressure/low pressure, high temperature/low temperature/local high temperature, oxygen-rich/oxygen-poor/protective gas). 

3、Battery short-circuit test: Battery short-circuit tests under different environmental conditions (high pressure/low pressure, high temperature/low temperature/local high temperature, oxygen-rich/oxygen-poor/protective gas).

4、Battery ignition test: Battery ignition tests under different environmental conditions (high pressure/low pressure, high temperature/low temperature/local high temperature, oxygen-rich/oxygen-poor/protective gas). 

5、 Battery charge and discharge tests: Battery charge and discharge tests under different environmental conditions (high air pressure/low air pressure, high environmental temperature/low environmental temperature/local high temperature, oxygen-rich/oxygen-poor/protective gas). 

 6、Battery fire extinguishing test: Battery thermal runaway fire extinguishing performance test under different environmental conditions (high pressure/low pressure, high temperature/low temperature/local high temperature, oxygen-rich/oxygen-poor/protective gas). 

7、Thermal shock test: Battery thermal shock tests under different environmental conditions (high pressure/low pressure, oxygen-rich/oxygen-poor/protective gas). 

8、Temperature cycling test: Temperature cycling performance test under different environmental conditions (high pressure/low pressure, oxygen-rich/oxygen-poor/protective gas).

What experimental data can researchers obtain with the help of the medium-sized comprehensive experimental module?

The measurable experimental data of the medium-sized comprehensive experimental cabin are as follows: thermal runaway temperature, gas production analysis, gas production component ratio, temperature field, gas production rate, fire extinguishing time, charging voltage, discharging voltage, charging current, discharging current, charging time, discharging time, whether there is a fire, whether there is an explosion, whether there is leakage, whether there is deformation, and electrical capacity, etc. This equipment is widely used in fields such as new energy safety laboratories, energy storage material technology, power engineering and engineering thermophysics, fire safety engineering, chemical science and technology, chemical engineering, and testing centers. It can also be used in conjunction with high-speed cameras, infrared video cameras, particle image velocimetry (PIV), planar laser induction analyzers (PLIF), mass spectrometers, laser igniters and other instruments, fully meeting different experimental requirements.

Does Dianshi Instrument have any cooperation cases with battery test chambers?

In 2024, the 82L medium-sized comprehensive laboratory module customized by Dianshi Instruments was successfully delivered to a university in Central China, earning high recognition from the cooperative client. This customized lithium battery comprehensive performance test chamber can build a composite experimental environment and support experiments such as battery ignition, heating, needle-puncture, compression, temperature cycling, and fire extinguishing. It can analyze the composition and concentration of products such as O2, CO, CO2, SO2, NH3, CH4, C2H4, and H2. 

 Dynamic demonstration of the medium-sized comprehensive experimental module: (1) Battery thermal runaway caused by physical impacts such as needle puncture and compression; (2) Laser-induced battery thermal runaway; (3) Local high temperature leads to thermal runaway of the battery.
