ROHM has recently integrated its 4th generation SiC MOSFET bare chips into the traction inverters of three ZEEKR EV models from Zhejiang Geely Holding Group (Geely), a prominent global automaker. Since 2023, these power modules have been mass-produced and supplied through HAIMOSIC (SHANGHAI) Co., Ltd., a joint venture between ROHM and Zhenghai Group Co., Ltd., to Viridi E-Mobility Technology (Ningbo) Co., Ltd., a key manufacturer under Geely. This collaboration, which began in 2018 with technical exchanges and evolved into a strategic partnership in 2021, has resulted in the adoption of ROHM’s SiC MOSFETs in the ZEEKR X, 009, and 001 models, significantly enhancing their cruising range and overall performance.
ROHM’s commitment to advancing SiC technology is evident in its plans to launch 5th generation SiC MOSFETs by 2025, with further advancements to follow. The company’s focus on providing SiC in various forms—including bare chips, discrete components, and modules—aims to facilitate the widespread adoption of this technology, contributing to a sustainable future. The ZEEKR models equipped with ROHM’s EcoSiC™ technology are notable for their performance: the ZEEKR X, a compact SUV with a cruising range exceeding 400km; the 009 minivan, with an impressive range of 822km; and the flagship 001, which offers over 400kW of power and a range of over 580km. These features make the ZEEKR models standout in the competitive EV market.
