The next generation of CAVs (Commercial and Construction Agriculture Vehicles)

Electrification of heavy-duty vehicles can help in saving the planet; making them smarter will reduce the Total Cost of Ownership (TCO)

Faced with new challenges, the modern automotive industry is forced to evolve and adapt to new conditions. Today, we have some revolutionary new technologies for efficient storage and distribution of electricity, making it a viable alternative to fossil fuels. Thanks to recent breakthroughs in semiconductor technology, electrical energy can now be used to power the next generation of commercial, construction, and agricultural vehicles (CAVs). It can help to reduce CO2 emissions and allows for autonomous driving and thus lowered total cost of ownership (TCO).

Electric buses used in urban transportation are among the first CAVs that have been completely electrified. In a typical CAV setup, there can be a lot of different subsystems, each with different power requirements. The low-voltage (LV) power network is used to provide power for some of the smaller systems such as the lighting, signalization, driver comfort, and similar, while the high-voltage (HV) power network is used for more power-demanding systems, including the drivetrain as the largest power consumer. Voltages in the HV domain can go up to nearly 1000 V.

Heavy-duty e-CAVs operate within a broad range of power, making them equally qualified for using both automotive and industrial-grade solutions 

When working with high voltages and high power, a special type of semiconductor with industrial rating is required. Infineon, as one of the world’s leading semiconductor manufacturer with over 40 years of experience in high power industrial and automotive applications, has an extensive portfolio of solutions for each application case in a typical electric CAV scenario: from power/high voltage motor driving solutions, all the way to low voltage/high-speed automotive-grade microcontrollers.

The HV domain is still largely dominated by Isolated Gate Bipolar Transistors (IGBTs), although some new technologies have already emerged like Silicon-Carbide (SiC)-devices. Infineon offers a wide range of IGBT modules starting with Easy 1B/2B for lower power, up to EconoDUAL 3™ based on the IGBT7 technology for up to 1200V, 900 A. Power modules integrate various switching topologies along with a NTC and integrated shunts for simple and reliable thermal monitoring and current sensing in EconoDUAL 3™ with an integrated shunt. Also, 1200V HybridPACK™ Drive, Power module for 800 V DC-link voltage with 3 NTC integrated can drive a 3 phase motor.

Produced using Infineon’s proprietary technology, the CoolSiC™ MOSFET family features some unique properties, offering new opportunities, not possible with Si-based technologies. These devices become increasingly popular due to their superior characteristics and potential to lower system costs. They are predestined to be used in high-frequency DC-DC conversion in EV battery charging applications.

Infineon’s power modules – both IGBT and SiC-MOSFET-based, use proprietary mounting technologies that provide lower contact resistance and simpler installation. Power modules provide an easy solution for the entire power stage.

Control circuitry is typically operated at much lower voltage levels. It also allows for advanced functionalities to be implemented such as the autonomous driving and driver assistance. Driving and controlling devices have to be compliant with very rigid automotive standards and regulations, especially ISO26262 and AEC-Q101. Infineon has an extensive and diversified portfolio of devices to cover this segment as well. The AURIX™ family of powerful and scalable 32-bit TriCore™ microcontrollers (MCUs) is specifically designed for automotive and industrial applications. These MCUs are in the heart of each subsystem, allowing independent but highly interconnected operation.

Going over the EiceDRIVER™ family of IGBT gate drivers, the OPTIREG™ family of automotive-grade power supply solutions with integrated safety features for ASIL relevant applications, and the whole range of sensors, cameras, CAN(FD)/LIN isolated communication circuits and other types of automotive-grade devices, Infineon offers the complete solution for each segment. Compliant with rigorous safety standards, Infineon’s automotive/industrial solutions enable the next generation of eco-friendly, autonomously driven CAVs, helping to save the planet while decreasing TCO through automatization.

As Infineon’s partner of choice in the EMEA region, EBV Elektronik is also ready to support your next-gen eCAV design. Our specialists will gladly provide you with both the components and the consulting as they did in the past 50 years, relying on the extensive experience and expertise.
