Why does lithium battery pack need aging test?

aging test

Lithium battery pack aging test is an indispensable procedure in the production process of lithium batteries. It is to better evaluate battery life and performance attenuation, so as to ensure the stability and reliability of factory batteries.

What is battery aging test ?

The battery aging test is a test that simulates the actual use of the battery, performs charge and discharge cycles on the battery, and records the performance of the battery. This kind of test is generally divided into normal temperature aging and high temperature aging. As the name implies, the battery is placed under normal temperature and high temperature conditions for charge and discharge cycle testing. In the battery aging test, the general test indicators involve the internal resistance, voltage and capacity of the battery, and these data are of great significance for the evaluation of the battery.

The purpose of the aging test

The purpose of aging test can be mainly explained from two aspects: enterprise and product.

From a enterprise perspective, product quality is an important factor that affects the company’s survival, and aging test is an important step in detecting battery quality. Only through battery aging test can the quality of the battery be guaranteed and customers can use high-quality products, high safety battery.

From the perspective of the product itself, the aging test can allow the electrolyte in the lithium battery to infiltrate better and the battery to react more completely; at the same time, it accelerates some side effects that may occur in the battery, allowing the lithium battery to reach the temperature state faster. The aging test can also expose some defective products in lithium batteries, making it easier to screen out lithium batteries with high consistency in the later stage, ensuring product quality.

To sum up, the importance of aging test of lithium battery packs is self-evident. As a professional lithium iron phosphate battery manufacturer, PLB has invested a lot of time and cost in aging test and established a professional aging workshop. We purchased a variety of aging cabinets from well-known brand manufacturers to meet the aging requirements of various battery packs, including: 15V/20A, 30V/10A, 60V/20A, 65V/20A, 75V/20A, 100V/15A, 100V/20A, 100V/ 100A, 750V/300A and these aging cabinets can meet the aging test of various battery packs below 750V/150A. At the same time, after more than ten years of development, PLB has accumulated rich aging experience, established a standardized aging process, and implemented digital management to continuously improve product quality, allowing customers to buy and use with confidence!

26650 battery vs 18650 battery, which is better？

图片
  26650 battery and 18650 battery 26650 and 18650 cells are a kind of cylindrical lithium batteries, both are mostly used in ternary lithium, lithium iron phosphate power batteries and have a place in the market. Most of 26650 battery are rechargeable LiFePO4 batteries. While most of 18650 battery are rechargeable ternary lithium batteries. Perhaps you can guess from the “name”，26550 cell is 65 mm in length and 26 mm in diameter. As you can tell from below picture, 18650 cell and 26650 cell have same length of 65mm, but the diameter is shorter, just 18 mm. 26650 battery  vs 18650 battery Performance It is well known that the cell is the foundation of the battery and the performance of the cell is related to the performance of the battery pack. ​Cell performance is determined by many aspects, the most fundamental and most important of which is safety. Safety Compared to ternary lithium-ion batteries, lithium iron phosphate batteries have higher safety because they use lithium iron phosp

What is OEM battery and ODM battery?

图片
In the battery industry, you may often hear about OEM battery and ODM battery, but the meaning and difference between the two may not be understood. Therefore, i will introduce the difference between OEM battery and ODM battery. What is OEM battery? OEM stands for Original Equipment Manufacturer. OEM battery refers to the manufacturer in accordance with the original design to produce processing batteries. At present, this way（phenomenon）is very common, many big brand manufacturers have their own OEM manufacturers, authorizing OEM manufacturers to manufacture and put their own brand label on product to sell it through selling brand value. That not only can reduce the production cost, but also improve the brand added value. What is ODM battery? The ODM stands for Original Design Manufacturer. ODM battery refers to the manufacturer’s design and production of batteries according to the specifications of the original factory. For example, a battery company wants to market a new battery pack
