ROHM’s 4th Technology SiC MOSFET Naked Chips Adopted in Three EV Fashions of ZEEKR from Geely

Integration in traction inverters extends the cruising vary and improves efficiency

ROHM has introduced the adoption of energy modules geared up with 4^th technology SiC MOSFET naked chips for the traction inverters in three fashions of ZEEKR EV model from Zhejiang Geely Holding Group (Geely), a prime 10 world automaker. Since 2023, these energy modules have been mass-produced and shipped from HAIMOSIC (SHANGHAI) Co., Ltd. – a three way partnership between ROHM and Zhenghai Group Co., Ltd. to Viridi E-Mobility Expertise (Ningbo) Co., Ltd, a Tier 1 producer beneath Geely.

Geely and ROHM have been collaborating since 2018, starting with technical exchanges, then later forming a strategic partnership centered on SiC energy gadgets in 2021. This led to the mixing of ROHM’s SiC MOSFETs into the traction inverters of three fashions: the ZEEKR X, 009, and 001. In every of those EVs, ROHM’s energy options centered on SiC MOSFETs play a key position in extending the cruising vary and enhancing total efficiency.

ROHM is dedicated to advancing SiC expertise, with plans to launch 5^th technology SiC MOSFETs in 2025 whereas accelerating market introduction of 6^th and seven^th technology gadgets. What’s extra, by providing SiC in varied types, together with naked chips, discrete elements, and modules, ROHM is ready to promote the widespread adoption of SiC expertise, contributing to the creation of a sustainable society.

ZEEKR Fashions Outfitted with ROHM’s EcoSiC

The ZEEKR X, which includes a most output exceeding 300kW and cruising vary of greater than 400km regardless of being a compact SUV, is attracting consideration even exterior of China on account of its distinctive value efficiency. The 009 minivan options an clever cockpit and huge 140kWh battery, attaining an excellent most cruising vary of 822km. And for these searching for superior efficiency, the flagship mannequin, 001, provides a most output of over 400kW from twin motors with a spread of over 580km together with a four-wheel impartial management system.

Market Background and ROHM’s EcoSiC

In recent times, there was a push to develop extra compact, environment friendly, light-weight electrical methods to increase the adoption of next-generation electrical automobiles (xEVs) and obtain environmental targets equivalent to carbon neutrality. For electrical automobiles particularly, enhancing the effectivity of the traction inverter, a key aspect of the drive system, is essential for extending the cruising vary and lowering the dimensions of the onboard battery, heightening expectations for SiC energy gadgets.

Because the world’s first provider to start mass manufacturing of SiC MOSFETs in 2010, ROHM continues to steer the business in SiC system expertise growth. These gadgets are actually marketed beneath the EcoSiC model, encompassing a complete lineup that features naked chips, discrete elements, and modules.

EcoSiC Model

EcoSiC is a model of gadgets that make the most of silicon carbide (SiC), which is attracting consideration within the energy system discipline for efficiency that surpasses silicon (Si). ROHM independently develops applied sciences important for the evolution of SiC, from wafer fabrication and manufacturing processes to packaging, and high quality management strategies. On the identical time, we’ve established an built-in manufacturing system all through the manufacturing course of, solidifying our place as a number one SiC provider.
