ROHM’s fourth-generation SiC MOSFET chips adopted in three Geely ZEEKR EV models
Japan-based power semiconductor device maker ROHM Co Ltd says that power modules equipped with 4th-generation silicon carbide (SiC) MOSFET bare chips have been adopted for the traction inverters in three models of the ZEEKR electric vehicle (EV) brand of China’s Zhejiang Geely Holding Group. Since 2023, these power modules have been mass produced and shipped from HAIMOSIC (SHANGHAI) Co Ltd – a joint venture between ROHM and Zhenghai Group Co Ltd – to Viridi E-Mobility Technology (Ningbo) Co Ltd, a tier-1 manufacturer under Geely.
Geely and ROHM have been collaborating since 2018, beginning with technical exchanges, then later forming a strategic partnership focused on SiC power devices in 2021. This has led to the integration of ROHM’s SiC MOSFETs into the traction inverters of three models:
- the ZEEKR X, which features a maximum output exceeding 300kW and cruising range of more than 400km despite being a compact SUV;
- the 009 minivan, which features an intelligent cockpit and large 140kWh battery, achieving a maximum cruising range of 822km;
- the flagship model 001, which offers a maximum output of over 400kW from dual motors with a range of over 580km along with a four-wheel independent control system.
In each of these EVs, ROHM’s power solutions centered on SiC MOSFETs are said to play a key role in extending the cruising range and enhancing overall performance.
ROHM plans to launch 5th-generation SiC MOSFETs in 2025 while accelerating market the introduction of 6th- and 7th-generation devices.
