Giving wings to travel: ADAS, electrification and Internet of Vehicles

The heart of an electric vehicle is its motor, and power semiconductors are the beating power of this heart. As the driver of the motor, power semiconductors are responsible for efficiently converting the electrical energy in the battery into the driving current and voltage required by the motor. This not only involves the efficiency of energy conversion, but also relates to the performance and response speed of the entire vehicle, which is the key to achieving efficient driving.

For electric vehicles, the on-board charging system is the main way to replenish electrical energy. In this process, power semiconductors play a vital role, converting alternating current from an external power source into direct current that can directly charge the battery. This requires not only high conversion efficiency, but also stability and reliability to ensure the safety and efficiency of the charging process.

As the energy source of electric vehicles, the performance and life of batteries directly determine the overall performance of electric vehicles. Here, power semiconductors, as the core of the battery management system, bear the important task of monitoring, protecting and managing the battery. It intelligently regulates the battery charging and discharging process to extend battery life and ensure safety during use.

The rise of V2X technology is revolutionizing our understanding of automotive connectivity. It represents the advanced ability of vehicles to connect via wireless networks to other vehicles, transportation infrastructure, pedestrians and even cloud services. The core of this innovative technology is that it gives vehicles the ability to collect and share road condition information in real time, greatly improving driving safety and efficiency. The U.S. National Highway Traffic Safety Administration (NHTSA) estimates that even employing just two V2X safety features, such as LiDAR and vehicle-to-vehicle radio communications, could save up to 1,000 lives and prevent approximately 500,000 traffic accidents each year.

The implementation of V2X technology relies on a series of advanced components, including sensors, cameras and multiple wireless connection technologies, such as WiFi, radio frequency, LTE and 5G cellular technology. These components work together to enable the car to fully share information with other vehicles, the driver, and the surrounding environment. For example, vehicles can receive critical information about traffic jams, accidents or weather changes in real time and adjust their routes based on this data. In addition, V2X technology can also provide advance warning of upcoming potential dangers, such as sudden appearance of pedestrians or vehicles, thus giving drivers more reaction time to avoid collisions.
