Global Footprints
Energy Storage System Battery Pack Automated Production Line
Lithium-ion batteries have been hailed as a low-cost alternative to lead-acid batteries, providing a new source of energy for abundant energy storage and electric vehicles.
Automatic cell sorting
Equipped with precision machinery and intelligent control systems, our automated production line features advanced cell screening and terminal positioning modules. These systems enable precise terminal positioning, guaranteeing consistent cell quality and high-precision spot welding, while effectively minimizing manual errors.
Cell Extrusion Technology
Precisely controls extrusion force to ensure structural stability.
Effectively prevents battery bulging, a common industry issue.
Reduces safety risks during battery transportation and operation.
Polarity Detection Technology
By detecting the positive and negative terminals of the battery, we ensure correct polarity connection during charging and operation.
This safeguards against short circuits, overheating and equipment damage, effectively ensuring safety and stable performance.
Automated Laser Welding
Our automated laser spot welding process, integrated with a precision terminal positioning system, enables deeper and more controlled welding. This ensures the melt depth and width of each weld point fully meet stringent standards, reduces internal resistance and voltage differences within the cell, and completely eliminates cold welds. As a result, the battery module achieves optimal performance and stability.
Based on extensive experience in lithium-ion technology, Greatech has developed a new generation of Energy Storage with two key advantages:
1.Greatech lithium batteries utilize prismatic cells featuring superior LiFePO4 (Lithium Iron Phosphate) technology. These cells deliver long cycle life and high energy density, making LiFePO4 the preferred choice for industrial and logistics applications. Importantly, this technology is non-flammable and non-explosive, even in the event of battery damage.
2.The batteries feature comprehensive protection. Cells are integrated into modules with laser-welded terminals, which effectively lower internal resistance and minimize the risk of poor connections.
Less dependent on the grid
Battery storage systems guarantee a continuous energy supply, even at times when the energy grid is unstable due to peaks in demand or extreme weather.
"Always on" supply
The sun is not always "on." A battery storage system works round the clock, and therefore compensates for any fluctuations in solar energy supply by storing any excess power in the system.
Resilience
A battery storage system provides emergency backup in the event of a power outage, guaranteeing business continuity.
