Infineon and Infypower to expand presence in new energy vehicle charger market

1 min read

Infineon Technologies is collaborating with Infypower, a Chinese company specialising in new energy vehicle charging.

Power semiconductors based on silicon carbide (SiC) offer several advantages, like high efficiency, power density, voltage resistance, and reliability, and provide opportunities for new applications and improved charging station technology innovations.

This collaboration will see Infineon provide INFY with 1200 V CoolSiC MOSFET power semiconductor devices to improve the efficiency of electric vehicle charging stations.

“The collaboration between Infineon and Infypower in the field of charging solutions for electric vehicles (EV) provides an excellent system-level technology solution for the local EV charging station industry,” said Dr. Peter Wawer, Division President of Infineon’s Green Industrial Power Division. “It will significantly improve charging efficiency, accelerate charging speed, and create a better user experience for owners of electric cars.”

SiC’s high power density enables the development of high-performance, lightweight, and compact chargers, especially for supercharging stations and ultra-compact wall-mounted DC charging stations. Compared to traditional silicon-based solutions, SiC technology in EV charging stations can increase efficiency by 1 percent, reducing energy losses and operating costs.

In a 100 kW charging station, for example, this translates to 1 kWh of electricity savings, saving 270 Euros annually and reducing carbon emissions by 3.5 tons. This drives the increasing adoption of SiC power devices in EV charging modules.

The CoolSiC MOSFET technology has been subjected to numerous stress tests and gate voltage jump stress tests before commercial release and regularly afterwards in form of monitoring to ensure highest gate reliability.

By integrating Infineon’s 1200 V CoolSiC MOSFETs, Infypower’s 30 kW DC charging module will be able to offer a wide constant power range, high power density, minimal electromagnetic radiation and interference, high protection performance and high reliability – making it suitable for the fast-charging demand of most EVs while possessing a higher efficiency of 1 percent compared with other solutions on the market. Consequently, significant energy savings and carbon dioxide emission reduction are achieved, which are leading at a global level.
