Product Description

Lithium ion battery pack short circuit testing machine Main Functions

Short-circuit simulation: Create short-circuits inside or outside the battery pack by mechanical or electrochemical means to simulate short-circuit failures in actual use.

Thermal runaway assessment: real-time monitoring of the temperature change of the battery pack during the short-circuit process, assessing its thermal runaway risk and thermal runaway behavior.

Safety testing: Evaluate the safety performance of the battery pack under short-circuit conditions, including whether smoke, fire, explosion and other dangerous situations will occur.

Data Acquisition and Analysis: Real-time acquisition of temperature, voltage, current and other data of the battery pack and generation of detailed test reports to help analyze the thermal runaway characteristics and safety performance of the battery pack.

Multiple safety protection: Equipped with multiple safety protection devices, such as explosion-proof box, explosion-proof door, pressure relief device, fire extinguishing system and emergency stop device, to ensure the safety of the testing process.

Environmental control: It can simulate short circuit under different environmental conditions (e.g. temperature, humidity) to evaluate the safety performance of battery packs in different environments.

Analysis of differences in test results of testers under different environmental conditions (e.g., high and low temperatures)

When conducting tests such as compression resistance and short-circuit testing of batteries or packaging materials, environmental conditions (e.g., high and low temperatures) have a significant impact on the test results. The following is a detailed analysis of the test results under different environmental conditions:

1. Test results under high temperature environment

1.1 Battery test equipment (e.g. lithium battery short-circuit tester, power battery short-circuit explosion-proof test chamber, etc.)

Increased risk of thermal runaway:

In a high temperature environment, the chemical reaction speed inside the battery is accelerated, resulting in the battery being more likely to reach a thermal runaway state. Test results show that the rate of temperature rise and the maximum temperature of the battery are usually higher at high temperatures than at room temperature.

For example, at 60C, the internal chemical reaction rate of a lithium-ion battery may be several times higher than at 25C, resulting in a shorter thermal runaway time.

Reduced safety:

At high temperatures, the battery's diaphragm and electrolyte materials may soften or decompose, further increasing the risk of short-circuit and thermal runaway.

The probability of the battery smoking, catching fire or exploding at high temperatures during testing increases, and the passing rate of the safety test decreases.

Performance degradation:

High temperatures accelerate the aging process of batteries, leading to a decrease in battery capacity and cycle life. Test results show that the capacity retention rate of batteries after cyclic charging and discharging at high temperature is low.

1.2 Testing equipment for packaging materials (e.g. carton compression tester, plastic container compression tester, etc.)

Material softening:

Under high temperature environment, the rigidity and strength of packaging materials such as plastics and rubbers will be reduced, resulting in a decrease in their compression resistance.

For example, the compressive strength of HDPE plastic drums at 60C may be reduced by more than 20% compared to that at 25C. - Material softening.

Increased deformation:

High temperature will make packaging materials more prone to plastic deformation, resulting in increased deformation under the same pressure.

Test results show that the deformation of carton at high temperature is usually more than 10% higher than that at room temperature.

Decreased stacking stability:

The stacking stability of packaging materials decreases under high temperature environment, and it is easy to collapse or deform during the stacking process.

2. Test results under low temperature environment

2.1 Battery test equipment

Battery performance decreases:

Low temperatures reduce the chemical reaction rate of the battery, resulting in a decrease in battery capacity and discharge performance.

For example, at temperatures as low as -20C, the capacity of a lithium-ion battery may be only about 70% of that at room temperature.

Increased internal resistance:

At low temperatures, the internal resistance of the battery increases, resulting in lower power output and efficiency.

Tests have shown that the internal resistance of batteries at low temperatures is typically more than 50% higher than at room temperature.

Increased safety:

Low temperatures slow down the rate of chemical reactions within the battery, reducing the risk of thermal runaway.

At low temperatures, the probability of thermal runaway is reduced and the safety test pass rate is increased.
