Cell Contacting System
Cell Contacting System, also known as interconnect plate or interconnect board, is primarily composed of signal collection components (such as FPC), plastic structural parts, copper and aluminum busbars.These components are connected into a whole through processes such as hot pressing or riveting to connect the battery cells, measure cell voltages & temperatures. It is mainly designed for mass production.
We have different Cell Contact System solutions for customers,
- Prismatic Cell - Cylinerical Cell - Pouch Cell
Plastic carrier,we have - PET film type, hot pressing PET films - Plastic Injection Tray, PC+ABS, PC+30GF, etc. - Vaccum Forming, PC
Sensing Part - Wire Harness with nickel tabs for laser welding, or wires ultrasonic welding directly - FPC
Busbar - Normally AL 1060 'O' Temper for serial connection
Manufacturing Service
Nickel foil to FPC connection strength: Cutting force > 100N, Peeling force > 25N
Nickel foil to copper bar connection strength: Cutting force > 300N, Peeling force > 60N
Connecting battery cells to form a complete battery module
Using laser or ultrasonic welding techniques to attach nickel tabs to aluminum busbars
In certain cases, components may need to be sub-assembled to ensure precision in subsequent steps
Visual and functional inspections are conducted on the welded components
Electrical performance tests, including voltage and temperature measurements,are carried out
The tested battery modules are packaged in preparation for shipment
Finally, the products are shipped to customers, completing the entire production process.
