Thanks to the warm attention of new energy, the power lithium-ion battery industry has also attracted much attention. Power lithium-ion battery is the power source for tools to supply power. It mostly supplies power for electric vehicles, electric bus, electric bicycles and sightseeing car. Focusing on the thermal runaway of power lithium-ion battery (mainly high-tem...
BMS failure mode The single failure of the battery is not only related to the battery itself, but also related to the failure of the battery management System BMS. BMS failure mode can also cause serious accidents, including the following categories: 1.BMS voltage test failure causes battery overcharge or over discharge: The voltage test line fails due to poor con...
So far, there are still a lot of people think that the temperature shock and temperature cycle test process and principle of the difference is not big, are to raise or drop the temperature of the test product test; Some people are cheated by the testers because they don't know enough about the differences between them. If you think there is no difference between temperat...
The Nail Penetration Test, an internal short circuit test method, is a safety test that tests the internal short circuit tolerance of lithium-ion batteries. The Needle Penetration Test is a test that uses a steel nail through the battery to simulate an internal short circuit to confirm whether the battery is smoking, catching fire, or breaking. In addition, the needling...
IEC 62619 specifies tests and requirements for secure secondary lithium batteries and cells used in industrial uses such as static applications. When there is an IEC 62619 standard specifying evaluation requirements and prerequisites of cells used in particular applications and will be in conflict with this record, the former takes precedence. Listed here are a few examp...
Usually, lithium-ion batteries are among the safest forms to use. However, if they're damaged or include defects, they may be dangerous for employees who control material handling equipment. Whenever you're on the market for a brand-new lithium-ion battery provider, UL 2580 battery safety test certificates are a must-have. The meticulous testing and product requirements ...
The ECE R100 standard test instructions are crucial for battery-electric car safety. The ECE R100 testing requirements for lithium-ion batteries apply to an all-electric powertrain in several vehicle classifications of N and M using a rate breaking stage of 25km/h. The ECE R100 requirements of electric vehicles employ their electrical health and use its electric energy s...
Temperature cycling test or thermal cycle testing is done on substances to determine the immunity of vulnerability to alternating extremes of low and high temperatures. You can utilize temperature cycling test chambers to test nearly all commercial goods to determine how they withstand extreme temperature changes. The intent of analyzing a product under these conditions ...
Every lithium-ion battery developed is required to meet certain requirements known as standards for battery testing that explains it’s action regarding safety usage, even when it’s implemented as a component in another technology. The standards for lithium battery testing are what battery manufacturing industries use in promoting their business with safety development. W...
Lithium battery, I think we should be more rigorous. It should be called 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 beryllium boron, carbon nitrogen, oxygen, fluorine and neon…”. Because Li has these characteristics, it is ...
What is UN Manual of Tests and Criteria Part III Subsection 38.3 In most of the guides of one equipment, you maybe find that it should be in accordance with the standard called UN Manual of Tests and Criteria Part III Subsection 38.3 ( also known as UN 38.3 Testing). You must wonder what exactly it is. Today’s guide will enable you to have a detailed knowledge of ...
What is thermal shock? Thermal shock means that due to the rapid heating or cooling, the object generates a large amount of heat exchange in a short time. When the temperature changes drastically, the object will produce thermal shock. This phenomenon is called thermal shock. When a metal material is subjected to rapid heating and cooling, a large temperature differenc...

Here is a piece of good news: This article will give you some insight into the humidity chamber (also known as humidity test chamber) in an all-round way. Whatever it is that you’re looking for, you’ll have ...
UN38.3 Standard Testing Items & Procedures The UN38.3 standard includes the following 8 detection items: T1 low pressure, T2 temperature cycle, T3 vibration, T4 shock, T5 external short circuit, T6 heavy object impact (lithium battery core), T7 overcharge (lithium battery or lithium battery ) T8 forced discharge (lithium battery cells). For lithium batteries ...
From the tropics to the frigid zone, from the plains to the plateau, from the ocean to space, etc., this makes the environment encountered in the storage, transportation and use of various products more and more complex. In order to ensure that the product can adapt to these complex and harsh environment, the product from the development of the need to consider its fu...
The salt spray test is one of the environmental tests. And it is usually carried out under artificial simulated salt spray conditions. The test mainly assesses the corrosion resistance of products or metal materials. The following are several types of salt spray tests: Natural environment exposure test Artificial acceleration simulation of salt spray environment t...
