The temperature humidity test chamber indicates the effect of temperature changes on materials and products. The temperature humidity test chamber aids effectively in ensuring positive outcomes in products with strict limits to failures. The humidity test chambers are developed in different sizes with a series

What are the main aspects of secondary battery performance? Voltage, internal resistance, capacity, internal pressure, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc., others are overcharge, over-discharge, solderability, corrosion resistance, etc. What are the electrical performance indicators of mobile phone battery

The mobile phone lithium battery is a finished battery composed of battery cell and battery protection board. The mobile phone lithium battery will be activated before leaving the factory. After a series of processes of filling the battery case with electrolyte-sealing-forming-dividing, the activation of the

Lithium battery, I think we should be more rigorous. It should be called the lithium-ion secondary battery. Li is the smallest diameter and most active metal on the element periodic table. If you are not sure, you can look at the periodic table “Lithium hydrogen-helium

In recent years, electric vehicles have become more and more popular, but electric vehicle accidents have occurred more and more frequently. Therefore, we need to know why the charging of electric vehicles will suddenly catch fire or explode? Line aging Electric vehicles have been used

The simple division of environmental testing can be divided into “climate environmental testing”, “mechanical environmental testing” and “comprehensive environmental testing”. Climate-related environmental tests include environmental stress tests such as temperature, humidity, and pressure, while mechanical environmental tests include environmental stress tests such as shock and

Environmental testing type Environmental chamber testing usually uses a single-factor test and multi-factor combination test, which act on the products in a certain order. To improve the accuracy and reliability of the test results, environmental tests have also begun to develop comprehensive tests, and actively develop
