In the fast lane of electric vehicle (EV) innovation, ROHM Co., Ltd. is steering ahead with its 4th-generation silicon carbide (SiC) MOSFET bare chips. These chips are not just components; they are the heartbeat of three new models from ZEEKR, a brand under Zhejiang Geely Holding Group. This partnership is a testament to the growing synergy between semiconductor technology and automotive engineering.

ROHM's SiC MOSFETs are integrated into the traction inverters of the ZEEKR X, 009, and 001 models. This integration is a game-changer. It enhances performance and extends the cruising range of these vehicles. Imagine driving an EV that can go further on a single charge. That’s the promise ROHM delivers.

The collaboration between ROHM and Geely began in 2018. It started with technical exchanges and blossomed into a strategic partnership focused on SiC power devices by 2021. This relationship has matured into a robust supply chain, with power modules mass-produced at HAIMOSIC (SHANGHAI) Co., Ltd., a joint venture between ROHM and Zhenghai Group Co., Ltd. These modules are then shipped to Viridi E-Mobility Technology, a Tier 1 manufacturer under Geely.

The ZEEKR X is a compact SUV that packs a punch. It boasts a maximum output exceeding 300 kW and a cruising range of over 400 km. This model is turning heads not just in China but globally, thanks to its impressive cost-performance ratio. It’s like finding a diamond in the rough—an affordable EV that doesn’t skimp on power or range.

Next up is the ZEEKR 009, a minivan that redefines family travel. With a large 140 kWh battery, it achieves a remarkable cruising range of 822 km. This model features an intelligent cockpit, making it a tech-savvy choice for modern families. It’s not just a vehicle; it’s a mobile command center.

Then there’s the flagship model, the ZEEKR 001. This beast offers a maximum output of over 400 kW from dual motors. It also features a four-wheel independent control system, ensuring superior performance on any terrain. With a range of over 580 km, it’s designed for those who crave adventure without the anxiety of running out of juice.

ROHM is not resting on its laurels. The company is committed to advancing SiC technology. Plans are already in motion for the launch of 5th-generation SiC MOSFETs in 2025. This forward-thinking approach will likely accelerate the market introduction of 6th- and 7th-generation devices. ROHM’s vision is clear: to promote the widespread adoption of SiC technology. This is not just about performance; it’s about creating a sustainable society.

SiC technology is a cornerstone of the EV revolution. It offers higher efficiency and better thermal performance compared to traditional silicon-based devices. This means longer ranges and faster charging times. In a world where time is money, these advantages are invaluable.

The partnership between ROHM and Geely is more than a business arrangement; it’s a shared vision for the future. Both companies understand the importance of innovation in the automotive sector. As the demand for electric vehicles continues to rise, so does the need for advanced technology that can keep pace.

The global automotive landscape is changing. Traditional combustion engines are gradually being replaced by electric powertrains. This shift is not just a trend; it’s a necessity. Climate change and environmental concerns are driving consumers toward greener alternatives. In this context, ROHM’s SiC technology is a beacon of hope.

The ZEEKR brand is positioned to capitalize on this shift. With its focus on performance and sustainability, it appeals to a new generation of drivers. These consumers are not just looking for a mode of transportation; they want a vehicle that aligns with their values. ZEEKR delivers on that promise.

As ROHM prepares to launch its next generation of SiC devices, the automotive industry watches closely. The potential for improved performance and efficiency is immense. This technology could redefine what consumers expect from electric vehicles.

In conclusion, the collaboration between ROHM and Geely is a powerful example of how technology and innovation can drive the future of transportation. With the integration of 4th-generation SiC MOSFETs in ZEEKR’s EV models, the road ahead looks promising. These vehicles are not just about getting from point A to point B; they represent a shift toward a more sustainable and efficient future. The journey has just begun, and the destination is electrifying.
