Rapid temperature-change test chamber( thermal chamber for battery testing ) in the new energy battery reliability testing plays an important role. Fast change rate temperature test is used to determine the adaptability of products for storage, transportation, and use in climatic environments with rapid changes in high and low temperatures. The test process generally takes room temperature → low temperature → low temperature stay → high temperature → high temperature stay → room temperature as a test cycle. Verification of samples through the temperature change or continuous temperature changes in the environment of the functional characteristics of the change.
The rapid temperature-change test chamber can be imitated in the new energy battery module design verification, so that the battery module can be in the general climate of long-term operation for more than 20 years. Through the fast temperature change test chamber test to confirm that the new energy battery can withstand high temperature and high humidity test after the impact of sub-zero temperature. As well as for the repeated changes in temperature caused by fatigue and thermal failure. In addition to determining the battery can resist the ability to penetrate the moisture for a long period of time, need to confirm that the battery in the test process whether the failure or failure. Through the battery open-circuit test system can be carried out to determine the failure of new energy batteries simple.

More stringent Battery testing
|
|
If you want to perform more stringent environmental tests on lithium batteries, you can choose a temperature shock chamber.
There are two types of thermal shock chamber, two-zones type and three-zones type. The test unit of the three-zone type thermal impact chamber is divided into three parts: high temperature zone, low temperature zone and test zone. The box of each zone has a unique heat breaking structure. Shock mode Switch the air channel to import the temperature to the test area for a hot and cold shock test. The two-zone cold and heat shock chamber test unit is divided into hot chamber and cold chamber. The hot and cold zones of the test parts can be quickly switched by carrying the basket. |
