Introduction to ROHM Semiconductor’s SiC Technologies
ROHM Semiconductor has achieved a remarkable milestone in electric vehicle technology by integrating its fourth-generation silicon carbide (SiC) MOSFET bare chips into the traction inverters of ZEEKR electric vehicle models. These vehicles, manufactured by Zhejiang Geely Holding Group, are equipped with high-performance power modules designed to optimize efficiency and extend the driving range.
Collaboration Between ROHM and Geely
The collaboration between ROHM and Geely began in 2018, evolving from initial technical discussions into a strategic partnership centered around SiC power devices. This partnership has led to the implementation of ROHM’s SiC MOSFETs in three specific ZEEKR models: the ZEEKR X, 009, and 001. Each of these vehicles highlights ROHM's cutting-edge power solutions that significantly improve their cruising range and overall performance, making them vital contenders in today’s competitive electric vehicle landscape.
ZEEKR X, 009, and 001 Overview
The ZEEKR X impresses with a maximum output exceeding 300kW and offers a cruising range of over 400km, all within a compact SUV design. The 009 minivan prioritizes comfort and efficiency, featuring an advanced cockpit and a substantial 140kWh battery that enables a cruising range of up to 822km. On the other hand, the flagship ZEEKR 001 is equipped with dual motors that provide maximum outputs over 400kW, along with a four-wheel independent control system, delivering exceptional performance and an impressive range of over 580km.
