FlexiblePCBsupplierChina talked features of FPC:

 

 

● High wiring and assembly density, eliminating the need for redundant cable connections.

 

● Good bendability, high softness and high reliability

 

● Small size, light weight and thin thickness

 

● Circuits can be set to increase wiring layers and flexibility

 

● Simple structure and easy installation

 

PCBsupplier talked application of FPC in new energy vehicles

 

 

For automobiles, whether it is fuel vehicles or intelligent vehicles, there are a large number of FPC applications, mainly in the automotive electronics sector.  Automotive electronics is a general term for automotive electronic control devices and automotive electronic control devices and mainly includes engine control system, chassis control system and automotive electronic control system.

 

The acquisition line is an important component required for the BMS system of new energy vehicles, which can monitor the voltage and temperature of the new energy power battery cells;Connect data acquisition and transmission with overcurrent protection function;Protect the car power battery cell, automatic disconnection of abnormal short circuit and other functions.

 

Previously, the power battery acquisition line of new energy vehicle adopted the traditional copper wire harness scheme.The conventional wire harness was made of plastic surrounded by copper wires, and each harness reached an electrode when connected to the battery pack.When there are many current signals in the power battery pack, many harnesses are required to cooperate, and the space is squeezed out.

 

In the pack assembly process, traditional wiring harnesses rely on workers to manually fix the ports to the battery pack, and the degree of automation is low.Compared with copper wire harnesses, FPC has outstanding advantages in safety, lightweight, and regular layout due to its high integration, ultra-thin thickness, ultra-softness and other characteristics.

 

In addition, the thickness of FPC is thin, the battery pack structure is customized, and FPC can be directly placed on the battery pack through the robotic arm during assembly, with a high degree of automation, which is suitable for large-scale mass production, and the trend of FPC replacing copper wire harnesses is clear.

 

Advantages of FPC in power battery modules

 

 

1.Highly integrated: self-embedded Fuse, connector, chip NTC, aluminum/nickel terminal.

 

2.Automatic assembly can be realized: fast and accurate assembly, which is conducive to automation.

 

3.Ultra-thin thickness: 0.34mm in the line area, 2mm at NTC.

 

4.Super softness: the line area can be bent and assembled at 90° and 180°.

 

5.Lightweight: When the whole vehicle is used, the weight can be reduced by about 1kg compared with the wiring harness solution.

 

6.Cost advantage: From the cost point of view, the cost of FPC itself is not high, and it is a great reduction in connection costs.

 

PCBmanufacturer talked,compared with copper wire harnesses, FPC has outstanding advantages in safety, lightweight, and regular layout due to its high integration, ultra-thin thickness, ultra-softness and other characteristics.
