[Editor's Note] The automobile industry is facing a new turning point due to the emergence of CO2 reduction, electric vehicles, and connectivity. Based on electrification, semiconductor technology is emerging as a key factor in the production of energy to operate automobiles, as well as in the operation and management of automobiles. High-efficiency power semiconductors are required to produce, transmit, and store electricity, and a number of automotive semiconductor technologies are required for communication and related automobile control, power management, and wireless transmission. Accordingly, semiconductor companies are also moving quickly to respond to the new mobility environment and are moving in earnest to provide semiconductor solutions across the entire electric energy chain. Accordingly, this magazine has prepared a space to examine semiconductor technology in the new era of mobility based on Infineon Technologies ' Driving the future of mobility .

■ High-speed charging of electric vehicles is possible with high-efficiency power semiconductors

German electric vehicle charger specialist Alpitronic recently launched a 50kW DC electric vehicle charger that can quickly charge one or two vehicles simultaneously at 25kW each via two charging ports.

This product is from Infineon./about-infineon/mobility/electric/?utm_source=e4ds&utm_medium=referral&utm_campaign=202208_ap_kr_c_cp.corporate.mobility&utm_content=article" target="_blank"> The EasyPACK™ CoolSiC module featuring 1200V CoolSiC MOSFET technology was used, and the charger has a compact footprint of 1,250x520x220㎣ and weighs less than 100㎏, yet achieves efficiency of up to 97% and enables a bidirectional design, showing the advantage of being able to mount the charger on an indoor wall.

The reason why such a high-performance yet compact product was possible is because of semiconductor technology.

The EasyPACK CoolSiC MOSFET module includes CoolSiC MOSFETs, NTC temperature sensors and PressFIT contact pins and increases power density by approximately 50%.

Electric vehicles are equipped with high-efficiency power semiconductors with high power density. Fast charging of the charging device for charging has become possible.

■ Electric vehicles, high-efficiency power semiconductor technology is inevitable

Such high-speed charging technology further expands the possibilities of mobility.

In the past, electric vehicles took hours to charge, and range was inevitably limited, but recent reductions in charging times have enabled long-distance driving and eliminated restrictions on charging areas.

This contributes to the spread of electric vehicles. In addition, the spread of electric vehicles will inevitably be accompanied by technological advancements in power semiconductors .





All electric motors are controlled by a main inverter , also known as a traction inverter , which converts DC to the AC needed to power the engine, and can vary the speed at which the motor turns by adjusting the AC frequency.

This minimizes power loss.al&utm_campaign=202208_ap_kr_c_cp.corporate.mobility&utm_content=article" target="_blank">A wide range of motor products is needed to improve inverter energy efficiency.

To this end, semiconductor companies are actively developing semiconductor products that can reduce costs while increasing efficiency, such as silicon carbide (SiC) semiconductors.

In addition, a battery management system (BMS) is essential to improve the efficiency.

All batteries require precise monitoring and control capabilities because batteries are very sensitive to precise discharge, charge current, voltage profile and temperature profile. To achieve this, a semiconductor-based BMS functions to monitor each cell, calculate the exact energy consumption using the parameters obtained when balancing, and predict the amount of energy remaining for the application.

■ Autonomous driving, ADAS , the future led by advanced semiconductors

Autonomous driving systems that used to assist drivers in the past are now used to help drivers relax ,ntricity/?utm_source=e4ds&utm_medium=referral&utm_campaign=202208_ap_kr_c_cp.corporate.mobility&utm_content=article" target="_blank">It is transforming into a system that creates a completely different dimension of time for work, entertainment, etc.

Advanced driver assistance systems (ADAS) , represented by autonomous driving, can react much faster than humans and detect potentially dangerous situations much earlier through networking with other vehicles and infrastructure.and help you drive in a more predictable manner.





This is possible because there are semiconductors that can communicate with various sensors .

Autonomous vehicles are equipped with a variety of sensors.Sonic sensors detect obstacles in situations such as parking, while radar sensors detect objects from a distance and measure speed and position relative to the vehicle’s own movement. Lidar sensors scan the surroundings with invisible laser light and create high-precision 3D images of the surroundings. Cameras provide important visual information such as the color and texture of objects, known as image patterns. Each of these sensor systems is reborn as precise, complete, and reliable information through sensor fusion.

Additionally, communications infrastructure such as Wi-Fi and 5G mobile networks allow vehicles to receive traffic information from other vehicles, infrastructure, and traffic control systems and use it for control purposes.





This is possible even outside the vehicle’s sensor range, allowing automakers to support multiple simultaneous applications, including driver and passenger devices streaming high-bandwidth data and media content, phone/tablet display mirroring, and external Wi-Fi hotspot access for on-the-go connectivity without relying on cellular data service.can support a variety of scenarios.
