Advantages and Applications of New Energy FPC

Currently, new energy FPC has become the most major choice for the vast majority of new energy vehicle models and has been widely used in newly launched new energy vehicles.

Introduction to FPC (Flexible Printed Circuit)

Flexible Printed Circuit (FPC) is a type of circuit board made with flexible copper-clad laminate as the base material. It serves as a medium for signal transmission and is used to connect electronic products, featuring high wiring density, good flexibility, light weight, and versatile manufacturing processes. FPC can generally be divided into single-sided FPC, double-sided FPC, multi-layer FPC, and rigid-flex PCB.

New Energy FPC Replacing Automotive Wiring Harness Systems

In the automotive sector, whether for commercial fuel vehicles or intelligent vehicles, the use of FPCs is extensive, mainly within engine control systems, chassis control systems and automotive electronic control systems.

Considering structure and space factors, future new energy vehicles will certainly adopt new energy FPCs extensively to replace wiring harnesses and will be used in multiple parts of the vehicle to achieve this. Therefore, the technology of new energy FPC in automotive electronics, especially in intelligent vehicles, is a very crucial trend, notably in battery BMS (Battery Management System), vehicle lighting systems, door control systems, camera modules, etc. Typically, an electric vehicle may use over 100 new energy FPCs, among which the new energy FPCs in battery BMS and vehicle camera modules have the highest application value and are key development areas.

Application of New Energy FPC in New Energy Vehicles

Collection wires are essential components of the BMS system in new energy vehicles, enabling monitoring of the voltage and temperature of new energy power battery cells; connecting data collection and transmission while providing overcurrent protection; protecting the power battery cells of vehicles, and automatically disconnecting in case of abnormal short circuits.

Previously, the collection wires for new energy vehicle power batteries used traditional copper wire harness solutions. Conventional wire harnesses are made by surrounding copper wires with plastic, with each harness reaching an electrode when connecting the battery pack. When many current signals are needed in the power battery pack, many harnesses are required, significantly occupying space.

In the assembly process, traditional harnesses rely on manual fixation of the ports onto the battery pack, resulting in low automation. Compared to copper wire harnesses, new energy FPCs have significant advantages in safety, lightweight, and neat layout due to their high integration, ultra-thin thickness, and ultra-flexibility. Additionally, new energy FPCs are thin and customized for battery pack structures. They can be directly placed on battery packs using robotic arms during assembly, achieving a high degree of automation, suitable for large-scale mass production. Therefore, the trend of new energy FPCs replacing copper wire harnesses is clear, with a broad market prospect.
