Zeekr integrates SiC MOSFETs from Rohm in three EV models

Power semiconductors Zeekr integrates SiC MOSFETs from Rohm in three EV models

2024-08-29 Source: Press release | Translated by AI 1 min Reading Time

Rohm's power modules with 4th generation SiC MOSFET chips are used for the production of traction inverters, which are implemented in three models of the Geely brand Zeekr. The Chinese car manufacturer and the Japanese semiconductor manufacturer have been cooperating since 2018—initially as part of a technical exchange, and from 2021 as part of a strategic partnership focusing on SiC power components.

The integration of SiC MOSFETs in the traction inverters of the Zeekr X, 009 and 001 improves the range of the electric vehicles and optimizes the overall performance. The Zeekr X SUV has a maximum output of over 300 kW and a range of more than 400 km (249 miles). The 009 minivan has an intelligent cockpit and a large 140 kWh battery, giving it a maximum range of 822 km (511 miles). The flagship model 001 scores with a maximum output of over 400 kW from two motors with a range of over 580 km (360 miles) and an independent four-wheel steering system.

Further developing SiC technology

Rohm is working on the further development of SiC technology and plans to launch 5th generation SiC MOSFETs in 2025. In addition, by offering SiC in various forms, including bare chips, discrete components and modules, the manufacturer can promote the widespread adoption of SiC technology. The Japanese company started mass production of SiC MOSFETs in 2010. These components are now marketed under the EcoSiC brand. EcoSiC is a trademark for Rohm products that use silicon carbide (SiC). SiC is considered a key material because it offers significant advantages in terms of efficiency and reliability, especially in high-performance applications such as electric vehicles. (se)
