Today’s cars are described as “computers on wheels” because they incorporate electronic, electrical, software and mechanical components. At the same time, we also see that the traditional mechanical system is gradually replaced by the E / E (electronic and electrical) architecture of automobile, with the emergence of automatic driving and new energy vehicles (nev).
1) Automatic driving
In the embedded system, the computing power is gradually reaching the technical limit of a single controller, and the bandwidth of internal domain and cross domain communication may not be enough to cope with the future data transmission. Although floating board to board connectors play an important role in these autopilot applications, this technology is challenging.
2) New energy vehicles
In terms of nev (new energy vehicle) design, it involves VCU (vehicle control unit), MCU (motor control unit), OBC (vehicle charging), PDU (power distribution device) and DC-DC (DC) conversion, as well as power supply module and control panel for charging station.
Due to the increasing demand for mileage, one of the main trends of nev is the transition from PHEV and HEV to bev. After that, it is expected to transition from Bev to fuel cell vehicle (FCV).
Similarly, the transition from a standard VDA battery module to a larger module with a higher proportion of CTP (battery pack) improves space utilization, increases energy density, and reduces the weight of the battery pack by reducing the number of parts.
FPCA (flexible printed circuit assembly) has many advantages for complex battery pack and BMS (battery management system) design, and will continue to replace wiring harness.
On the other hand, the current connector solutions for nev are facing many challenges, that is, to reduce the weight of the vehicle. EV battery pack accounts for a large part of the weight of the vehicle, and also takes up a lot of space. Compared with traditional wiring harness, these factors require smaller and lighter connectors. Flexible printed circuit (FPC) can be used as a substitute for traditional line to board connector to provide a lighter product. At the same time, the flexibility of the product allows it to be suitable for compact space, which is required by today’s top battery pack internal high-density multi cell structure.
Molex believes that the trend in the future will be towards very compact and stable connector solutions, which will help adapt to the robot assembly process. Molex integrates fakra’s camera rear shell connector and the new ultra small floating board to board connector, which is the best example. The floating board to board connector can realize the robot assembly process, and its small size provides the maximum design flexibility and reduces the space between the camera and the host circuit board. These advantages are suitable for compact and high resolution camera applications.
In addition, flexible printed circuit (FPC) can provide a lighter alternative to the traditional line to board connector. At the same time, the flexibility of the product is suitable for the compact structure, and can solve the problem of limited space faced by today’s automotive electronics.
Molex high speed FFC / FPC connector is suitable for the display’s demand for slim products, which contributes to the development of digital cab in the future, that is, to the future safe and comfortable driving.
