Environmental Testing of Rechargeable Battery
Feb 21, 2025
Rechargeable battery, which can be re-active by charging after be used. They are widely used in the fields of environmentally friendly vehicles, power storage, and Dynamic field.
Environmental testing of rechargeable battery is an important means of evaluating their performance under different environmental conditions.
Ⅰ. Testing Purpose
The environmental testing of rechargeable battery aims to simulate various conditions that may be encountered in actual usage environments to evaluate the reliability and performance of the battery. Through testing, it is possible to understand the conditions of working battery under different temperature, humidity, vibration, impact and other conditions, providing scientific basis for the research and development, production and use of battery.
Ⅱ. Testing content
A. Temperature testing
a. High temperature test: Rich a high temperature environment to observe its temperature stability and the risk of thermal runaway.
b. Low temperature testing: Testing the discharge performance, capacity degradation, and low-temperature starting ability of the battery under low temperature conditions.
c. Temperature cycling test: Simulate the temperature changes that the battery may experience in actual use, evaluate its thermal durability and cycle life.
B. Humidity test: Evaluate the battery’s performance, sealing, and corrosion resistance in a humid environments.
C. Vibration testing: Through simulate the battery in the vibration environment that may encounter during transportation, installation, and use, evaluate its structural integrity, electrical connection reliability, and performance stability.
D. Impact testing: Through simulating the battery in unexpected situations such as drops and collisions, and evaluate their impact resistance.
E. External short circuit test: Test the performance of the battery under external short circuit conditions, including risks of thermal runaway and explosion and so on.
Ⅲ. Test standards and specifications
The environmental testing of rechargeable battery should follow relevant testing standards and specifications to ensure the accuracy and comparability of test results. Common testing standards include:
IEC 62133/ IEC 61960、UN 38.3、UL 1642/UL 2580、GB/T 31467、JIS C 8714
Ⅳ、Test equipment
Environmental testing on rechargeable battery requires the professional testing equipment and methods. Common testing equipment includes：
High and low temperature test chamber: Used to simulate different temperature environments.
Humidity test chamber: used to evaluate the performance of battery in humid environments.
Vibration test bench: Simulate vibration environment to evaluate the structural integrity and performance stability of battery.
Impact testing machine: used to simulate impacts in unexpected situations such as drops and collisions.
Ⅴ、Test results and evaluation
After completing the test, it is necessary to analyze and evaluate the test results. Based on test data and standard requirements, determine whether the performance of the battery meets the requirements under different environmental conditions. For undesirable battery, further analysis and corresponding improvement measures should be taken.
In summary, environmental testing of rechargeable battery is an important means to ensure their stable and reliable performance in practical use. Professional testing instruments can provide more professional, safe, scientific and effective experimental results for rechargeable battery testing, greatly reducing the cost of testing and bringing convenience to companies.
