DC Fast Charging Solutions for Electric Vehicles

DC fast charging solutions for electric vehicles to meet the charging needs of electric vehicles. As the number of electric vehicles on the market continues to grow and many national and regional governments require zero emissions by 2050, there is an urgent need for more efficient charging solutions. Various consumer studies have shown that the availability and length of charging heavily influence user acceptance of electric vehicles, and high-power DC charging stations are the solution to meet this market demand.

Today, conventional electric vehicles can be fully charged to 80% of battery capacity in 10 minutes, a charging speed comparable to the refueling speed of a conventional internal combustion engine vehicle. Infineon can help enable energy-efficient DC fast charging designs, allowing you to benefit from a comprehensive, ready-to-implement, one-stop product and design portfolio covering power conversion, microcontrollers, safety and security, auxiliary power, and communication product families.

Advanced Solutions

Infineon offers advanced solutions, from control to sensing to next-generation safety and connectivity.

Infineon offers cost-effective discrete products for DC electric vehicle charging designs up to 150kW, including the 600V CoolMOS™ super junction MOSFET P7 and CFD7 series, 650V IGBT TRENCHSTOP™ 5 and 1200V CoolSiC™ MOSFETs. The CoolMOS™ and CoolSiC™ MOSFETs are distinguished by high-frequency operation, high power density, and low switching losses, which improve the efficiency of various battery charging systems. Infineon's high-voltage switch product family also includes 650V and 1200V CoolSiC™ Schottky diodes. Since each switch requires a driver and each driver requires control, adapted EiceDRIVER™ gate drivers are available, as well as XMC™ and AURIX™ microcontrollers for electric vehicle charging designs. Chargers with a power capacity above 50kW typically use IGBT CoolSiC™ MOSFETs and diode power modules such as the CoolSiC™ Easy module, IGBT EconoPACK™, and IGBT EconoDUAL™ series. Charging posts with capacities above 100kW are typically modular with stacked subunits. These subunits are available in capacities of 20kW-50kW per unit and are expected to expand in future designs.
