Temperature cycling test is an essential method in battery abuse tests, which can offer deeper research into the reliability and durability of battery and its components in the strict and extreme temperature situation. This test mainly exposes sample with rapid ramp rate between certain temperature range. Different standards have different requirements to the raising and cooling rate. Normally, most standards (like UN38.3, UL1642 and IEC 62133) require about 3-5 celsius per minute from temperature range between -40~+70 celsius. After doing such kind of test, it will help the users (engineers, researchers and professors) judge how great the battery can have good ability of resisting fluctuations during its environment. In addition, the precious test data can be taken advantage of enhancing and optimizing production procedures, which ensure to pro-long the life cycles of battery and cut down some costs, such as operation and time. By writing this article, it will help discover the advantages of temperature cycling test for safety applications and can have more discussion why it’s an efficient and effective way for making assessment of sample’s performance in harsh and full of challenging environmental conditions.
Enhanced Durability and Reliability of Battery in the Test
Temperature cycling test has different names in different standards. Few of them might call it thermal heat or thermal shock. This test provides lots of benefits to lithium battery abuse test. The most important one is to offer improvement for the sample’s durability during such a test. Usually, the users like to run temperature cycles for their battery by repeating and changing ramp rate of temperature. Besides, the users also use charge and discharge device to connect sample in such a changing temperature situation. If battery doesn’t explode or be on fire, then it has so good durability and reliability. Thus, temperature cycle test enables to verify weaknesses and faults in battery which can have consequence to product’s failure while put in an real environment. By testing battery, the users can determine its safety performance and understand how to improve the product quality when in usage. Besides, the manufacturers can have more confidence in their products and invest a lot of money into developing a new-high-quality-and-cost-friendly products.
Reasons of Carrying out Temperature Cycling Test
The reasons why it’s significant to conduct temperature cycling test is as following:
1) It’s a practical method for battery safety abuse test, which can help detect product failure caused by the temperature rapid changes in a short time.
2) By taking action of exposing a battery to harsh-and-extreme changing temperature environment, the manufacturer can observe weakness and verify some potential bugs and faults before rolling out their final and safe product into the market. Such kind of test can ensure to satisfy customers to some extent
3) This test also make sure that battery will be able to bear shifts in its environmental conditions all in a sudden without appearing faults and failures, which greatly ensure to satisfy customers towards lithium battery.
Re-built Actual Situations for Engineering Assessment
Temperature cycle test plays an important role in offering engineering assessment with the simulation of real-world. The evaluation can help verify how a battery will react while exposed to fast changing in temperature and humidity. Besides, it is mainly used as a environment range to make evaluations, such as aging, corrosion resistance and the life cycle of acceleration. By re-building the impacts of strict-and-extreme temperatures as well as other variables under different environments on battery or its components, engineers or researchers can figure out solutions which have better preparation for long-time usage in the harsh environmental situations. Compared with the traditional methods which carried out experiment in real environments, temperature cycling test chamber can offer different combination tests and have more benefits than the old ones.
Improved Efficiency in Production Test
As mentioned in the previous paragraph. Temperature cycling test is an effect process in abuse testing, which can have improvement of the efficiency to production line and product test. By conducting this test, the researchers and manufacturers will obtain test results sooner and sooner. They can evaluate their product performance in various situations and implement some necessary adjustments or changes based on test data. The components of battery will be guaranteed to meet quality standards and regulations. Meanwhile, it is sure to save much time. With this test method, most companies are able to cut down large budget on battery development by detecting and verifying any potential problems in a early stage, instead of waiting till the later period of time when they find it’s very expensive to fix and deal with.
Summary
When it comes to the temperature cycling test, it has been performed to enhance battery integrity and reliability with a wide environmental range of usage. By re-buliding actual world situations in a chamber, researchers are able to take use of these tests to verify product failures so that it can avoid issues becoming very serious in production. Therefore, such kind of test has offered plenty of advantages for producing good quality battery.
