01 Laser Welding Production Line
We can realize high-precision welding of cell connection, wire connection, and battery box packaging, while providing more uniform welding quality and current conduction performance.
Through laser welding, high-strength, reliable sealing welds can be achieved to prevent leakage of electrolyte inside the battery pack or intrusion of foreign substances.
It can improve efficiency and quality, and ensure that the battery pack has good connection and reliability during use.
02 Battery Pack Productin line
with 4 energy storage PACK lines and 4 power PACK lines, we can assembly the battery packs according to design requirements, including connecting battery cells to form batteries in series or parallel, installing BMS and other auxiliary equipment, connecting wires and connectors, and installing casings and protective devices.
03 Battery Aging Workshop
In our well-equipped battery aging test workshop, battery aging tests can be carried out under different conditions, such as high & low temperatures, rapid charge & discharge, etc. By simulating different working environments and usage conditions, the performance and attenuation of batteries can be evaluated.
We have enough aging equipmen to perform aging tests on 1,500 sets of batteries at the same time, and can realize full inspection and 3 times aging test of each battery pack before shipment.
04 Collection Line Workshop
collecting wires are key components connecting battery cells or battery packs inside energy storage devices for collecting, transmitting, and distributing current.
The main task of the collection line workshop is to manufacture and assemble high-quality collection lines to ensure the normal operation and performance of energy storage equipment.
05 Finished Product Testing Workshop
Our test workshop comprises five state-of-the-art laboratories dedicated to conducting comprehensive tests and experiments, meticulously evaluating the electrical performance, safety, reliability, mechanical characteristics, and environmental adaptability of all our products.
In addition to functional inspections, we prioritize thorough assessments of product appearance, ensuring that our stringent quality standards extend to the visual presentation of our offerings.
