With the rapid development of electric vehicles and energy storage technology, the performance and cost of battery modules as core components directly affect the competitiveness of the entire system. CCS technology, as an excellent battery module connection technology, not only achieves effective series parallel connection of battery cells, but also integrates functions such as temperature sampling and voltage sampling. Through signal acquisition components such as FPC (flexible circuit board) or PCB (printed circuit board), it provides real-time data for BMS (battery management system), greatly improving the intelligent management level of battery modules. Huiyao Laser has keenly captured this technological trend and decided to use CCS technology as an important lever to promote intelligent manufacturing.

Product Introduction  

CCS intelligent manufacturing production line is a highly integrated, flexible and versatile system. It not only includes effective automation equipment such as wire harness isolation board feeding machine and bar plate automatic feeding machine, but also introduces core process equipment such as single/multi-point riveting machine and nickel plate laser welding machine, as well as precision testing equipment such as electrical performance automatic testing machine and AOI (automatic optical inspection) testing machine. We can integrate design services such as manual and automatic production lines according to customer needs.

Product advantages  

In the practice of CCS intelligent manufacturing, laser welding technology has played an irreplaceable role. Laser welding technology, with its unique advantages such as small focusing spot, fast welding speed, and strong adaptability, ensures the quality stability and reliability of CCS connection points, providing solid technical support for intelligent manufacturing.

The company relies on its profound accumulation in the field of laser technology to apply laser welding technology to the automated production line of battery modules, achieving high-precision, high-efficiency, and low pollution welding processes. It has successfully created a production line that integrates high automation and flexibility. The line cleverly integrates artificial intelligence and excellent equipment, realizing an intelligent production process from wire harness isolation board loading to automatic electrical performance testing.
