Printed circuit boards are widely used in new energy vehicles, and they play an important role in improving vehicle performance, safety, and user experience. PCBs not only connect and support various electronic components, but are also responsible for the transmission of power and signals. In new energy vehicles, the importance of PCBs has become increasingly prominent due to the increase in electronic components and the demand for highly integrated, high-density, and multi-layered PCBs.
Main application areas
1. Safety system
PCBs play a key role in the vehicle's safety system. For example, the implementation of various functions of ADAS (Advanced Driver Assistance System) requires highly reliable electrical connections and signal transmission to ensure the safety of drivers and passengers.
2. Entertainment system
Infotainment systems are also an important application area for PCBs. These systems provide a rich multimedia experience, including audio, video, and other interactive functions, which improves driving comfort and convenience.
3. Electronic control system
The electronic control system of new energy vehicles has special requirements for PCB. The average value of PCBs carried by pure electric vehicles is about 5 to 6 times that of traditional fuel vehicles. Among them, the electronic control system has the highest value of PCBs in the car, accounting for about half of the value of the PCBs in the whole vehicle.
4. Instrument panel and control unit
PCB is used to manufacture instrument panels and control units, which are responsible for displaying various status information of the vehicle and allowing the driver to operate. The instrument panel of modern cars is usually equipped with complex electronic control systems, which require high-performance PCBs to support.
5. In-vehicle communication system
With the development of Internet of Vehicles technology, in-vehicle communication systems have become increasingly important. PCBs are used in these systems to transmit data and signals and support the connection of vehicles to external networks.
6. Engine control unit
Although new energy vehicles do not use traditional internal combustion engines, they still require control units to manage electric motors and other key components. These control units rely on high-performance PCBs to perform complex computing and control tasks.
7. Lighting system
LED lights and other lighting equipment also require PCB support. PCB can accurately control the brightness and color of LEDs, providing better lighting effects and lower energy consumption.
8. Control modules and sensors
Various control modules and sensors in new energy vehicles require PCBs for connection and power supply. These modules and sensors are responsible for monitoring the status of the vehicle and providing feedback, which is essential for the safe operation of the vehicle.
9. Charging piles and charging equipment
With the popularity of electric vehicles, the demand for charging piles and charging equipment is also growing. These devices contain complex circuits inside, and high-quality PCBs are required to ensure the safety and efficiency of the charging process.
With the continuous expansion of the new energy vehicle market and the advancement of technology, the application of PCBs in automobiles will continue to expand. It is expected that by 2026, the output value of automotive PCBs is expected to grow to US$14.5 billion, and the proportion of the overall PCB output value will rise to 15%. In addition, with the development of autonomous driving technology, the demand for high-layer HDI and high-frequency PCBs will also increase.
In summary, the application of PCBs in new energy vehicles covers all aspects from safety systems to entertainment systems, and is an indispensable part of modern cars. With the continuous advancement of technology, we can expect more innovative applications of PCBs in future cars.
