Accelerating the Future: FPC Manufacturing for New Energy Vehicles

In this rapidly evolving world, the automotive industry is witnessing a paradigm shift towards sustainable mobility. As the demand for new energy vehicles continues to surge, the key to achieving this transformation lies in the accelerated development of flexible printed circuit (FPC) manufacturing. FPC technology has emerged as a game-changer, enabling the creation of lighter, more efficient, and environmentally friendly vehicles.

The importance of FPC manufacturing in accelerating the future of new energy vehicles cannot be overstated. By integrating advanced electronics and power management systems, FPCs contribute significantly to enhancing the overall performance and safety of these vehicles. Moreover, FPCs enable the seamless integration of automotive sensors, control units, and communication systems, ensuring a seamless driving experience.

Manufacturers are investing heavily in research and development to further enhance FPC manufacturing processes and capabilities. This includes refining the design and fabrication techniques to create FPCs that are not only highly durable but also adaptable to the complex requirements of new energy vehicles. With continuous innovation, FPCs are becoming increasingly compact, lightweight, and resistant to extreme conditions, paving the way for superior automotive performance.

This accelerated focus on FPC manufacturing for new energy vehicles is instrumental in reducing carbon emissions, minimizing reliance on fossil fuels, and driving the global transition towards a greener future. By supporting the growing demand for electric and hybrid vehicles, FPCs are revolutionizing the automobile industry and accelerating the adoption of sustainable transportation.

In conclusion, the FPC manufacturing industry is at the forefront of propelling the future of new energy vehicles. Through ongoing advancements, FPCs are poised to revolutionize the automotive industry by enabling enhanced performance, increased efficiency, and a more sustainable mode of transportation. As we look ahead, the collaboration between FPC manufacturers, automakers, and technology pioneers will play a pivotal role in accelerating this transformative journey towards cleaner and greener mobility.

Introduction to FPC (Flexible Printed Circuit)

Flexible Printed Circuit (FPC) is a type of circuit board made from flexible copper-clad laminate. It is used as a medium for signal transmission in electronic products, and it has the advantages of high wiring assembly density, good bending flexibility, lightweight, and flexible manufacturing process. FPC can generally be divided into single-layer FPC, double-layer FPC, multi-layer FPC, and rigid-flex FPC.


With the development of electric and intelligent vehicles, the advantages of FPC in terms of bending flexibility, weight reduction, and high automation level have been further highlighted. The use of FPC in the automotive field has been increasing, covering applications in areas such as vehicle lights, display modules, BMS/VCU/MCU power control systems, sensors, and advanced assistance systems. The rapid development of new energy vehicles has led to a significant increase in the demand for FPC used in vehicle power batteries.




Application of FPC in new energy vehicles


The collection line is an important component equipped in the BMS system of new energy vehicles, which monitors the voltage and temperature of the power battery cells. It connects data collection and transmission and includes overcurrent protection functions. It protects the power battery cells and automatically disconnects in case of abnormal short circuit, among other functions.

Previously, traditional copper wire harness solutions were used for the collection lines of new energy vehicle power batteries. Conventional wire harnesses are made of copper wires surrounded by plastic. When connecting to the battery pack, each wire harness reaches an electrode. When there are many current signals in the power battery pack, a large number of wire harnesses are required, occupying a significant amount of space. In the pack assembly process, traditional wire harnesses rely on manual fixing of the ports to the battery pack, resulting in low automation level.

Compared to copper wire harnesses, FPC has outstanding advantages in terms of safety, lightweight, and orderly layout due to its high integration, ultra-thin thickness, and flexibility. In addition, FPC is thin and can be customized to the battery pack structure. It can be directly placed on the battery pack by a robotic arm during assembly, with a high level of automation, making it suitable for large-scale production. The trend of FPC replacing copper wire harnesses is clear.

In the early years around 2017, due to the high cost of small-scale production and the high reliability requirements in the automotive electronics field, most power battery companies were in a wait-and-see attitude. With the excellent performance demonstrated by FPC and the rapid cost reduction brought by large-scale production, the process of FPC replacing traditional wire harnesses has accelerated significantly. A survey conducted by High Great Lithium Batteries in 2018 showed that leading domestic power battery companies such as CATL (Contemporary Amperex Technology Co., Ltd.) and BYD (Build Your Dreams) have already applied FPC in pack assembly in large quantities. Public information shows that companies such as Tesla, Guoxuan High-tech, CALB (China Aviation Lithium Battery), Tafel, EVE Energy, and Funeng have also started using FPC. Currently, FPC solutions have become the main choice for the majority of new energy vehicle models.
