High-Power Solutions for Fast EV Charging

Encouraging drivers to make electric vehicles their primary means of transportation relies heavily on finding ways to extend their range. Infineon helps users realize energy-efficient DC fast-charging designs with an excellent price-performance ratio. While carmakers are working on more efficient batteries, building a powerful, convenient, and accessible charging infrastructure is equally important. High-power DC charging systems of up to 350 kW already allow drivers today to add 200 km to their battery in about seven minutes, which is comparable to refueling a car with an internal combustion engine. The technology behind what makes these chargers fast, efficient, and accessible helps eliminate "range anxiety" among drivers and further promotes EV adoption worldwide.

Selecting the Right Components

When selecting the ideal power semiconductor, it is essential to know the power level of the charger. Chargers in the power range above 50 kW are typically built with IGBTs, CoolSiC™ MOSFETs, and diode power modules from Infineon, such as the CoolSiC™ Easy Module, IGBT EconoPACK™, and the IGBT EconoDUAL™ family. With sub-units ranging from 50 kW to 100 kW, chargers with a power range of more than 100 kW are built by stacking the sub-units.

Infineon's high-quality portfolio of circuit breakers works seamlessly with its wide range of drivers. That is why Infineon also offers the right EiceDRIVER™, XMC™, and AURIX™ microcontrollers for customers' fast EV charging concepts. For inverter management, high-precision coreless current sensors provide the ideal solution for inverter control and diagnostics, and Infineon's OPTIGA™ products ensure data protection and safety at the charging station.
