Semco Infratech’s SI-R Laser Cleaning & CCD Tester for prismatic cells is a dedicated station that combines laser-based pole surface cleaning with automated polarity detection to improve weld quality and assembly safety in lithium-ion prismatic cell packs. Why laser cleaning and CCD testing matter As prismatic cell formats become standard for EV and BESS applications, […]

  A crucial safety and quality testing step in the fields of electric vehicles, energy storage systems, and consumer electronics is the “battery pack immersion test.” It primarily verifies the integrity of the battery pack’s seal, ensuring it can prevent moisture intrusion and thus avoid serious problems such as short circuits, corrosion, leakage, and even

As products become more advanced and are expected to perform flawlessly in every environment, manufacturers can no longer rely solely on functional testing. Products must withstand extreme heat, freezing temperatures, high humidity, and rapid environmental changes throughout their lifecycle. This is where constant temperature and humidity test chambers become an essential part of quality assurance.

The energy storage battery (we commonly use lithium-ion batteries) loses heat control, which is to say, the battery “produces heat much faster than it dissipates heat,” causing a chain reaction that burns more and more intensely, and when severe, it will catch fire and explode. The reason why this situation occurs is either that the

Connecting two battery banks with a large voltage difference directly in parallel not only significantly degrades battery performance but also creates serious safety hazards. The core premise of parallel battery connection is that the voltages must be essentially the same. Once the voltage difference exceeds a safe threshold, a series of negative problems will follow,

CCS integrated bus is the core connection part of PACK. On the one hand, it is the “main vessel” of PACK, carrying the large current transmission of DC main circuit of PACK. On the other hand, PACK’s “Divine Network” accurately collects the voltage and temperature signals of the cells to provide accurate data for the

With the booming development of the new energy vehicle market, power lithium batteries are the core components, and their production line technology is also receiving increasing attention. In the production process of power lithium batteries, the module line and the Pack line are two indispensable key links. This article will deeply analyze the difference between

As the global demand for lithium-ion batteries continues to accelerate, driven by electric vehicles (EVs), energy storage systems (ESS), and renewable energy integration, battery manufacturers are under increasing pressure to improve production efficiency, consistency, and scalability. While much attention is given to cells, modules, and battery management systems, one critical component often overlooked is the

1. Overview & Configuration The 1P52S lithium battery module consists of 52 prismatic LFP (Lithium Iron Phosphate) cells connected in series, with no parallel strings (1P). This is the industry-standard configuration for BESS energy storage modules used widely in grid-scale applications. The module typically includes 52 prismatic LFP cells, an internal BMS, a CCS (Cell

Low temperatures are a “performance killer” for energy storage batteries, directly leading to capacity decay, decreased charge and discharge efficiency, accelerated aging, and potential safety hazards. Proper winter maintenance is crucial for ensuring stable operation and extending the lifespan of equipment. The core principles revolve around temperature control and power preservation, scientific charging and discharging,
