These system solutions reduce customers’ development time/cost by combining our broad product portfolio which has been enhanced through strategic acquisitions.

Another example of our “Winning Combinations” is our best-in-class compact 100KW inverter turn-key solution. We offer a reference board embedding our MCU, PMIC, IGBT and gate drivers along with model and software drivers to support customer design in. We even built our own demo EV car to evaluate the inverter turn-key solution in a real car in motion.

How Renesas solutions address specific attributes such as low voltage and cost, functionality and efficiency, or high power and torque.

We have started sample shipment of our new Si-IGBT product using our latest AE5 process to realize a small footprint and low power losses for EV inverters (press release), thus making smaller and more efficient inverters possible. These Si-IGBTs will be produced at our 300mm fab in Kofu, Yamanashi Prefecture in Japan where last year we announced 90 billion yen of investment to launch a new production line to capture the increasing demand in the EV space (press release). We also expect the new generation AE5 products to be 10 percent smaller than our previous products while maintaining Renesas’ distinctive high reliability and robustness.

EV-SolutionIndeed a robust strategic move to further foster the company’s EV focus in the market, hence kindly tell us about Renesas and Tata Group’s Tata Elxsi’s new Next-gen EV Innovation Center (NEVIC). 

Tata is a very strategic partner for us to promote our solutions in India and emerging markets. In June 2022, Renesas announced the partnership which spans broad applications including automotive, IoT and 5G systems (press release). Prior to that, Renesas and Tata Elxsi jointly established NEVIC in January last year (press release).

As part of the broad partnership with the Tata group, Renesas and Tata Motors are collaborating on developing next-generation automotive electronics to drive leadership performance and scalability for vehicles with ADAS.

This collaboration aims to address the fundamental requirements, allowing customers to concentrate on unique features. Through these product and service offerings, Tata Elxsi and Renesas are supporting the acceleration of eMobility, particularly the two-wheel and light EV segments, assisting clients in overcoming time-to-market and technology complexity.

How is Renesas supporting the movement towards carbon neutrality? Also, Renesas’ has been known for its Power semiconductor leadership, how is the company targeting new potential segments like EVs with advanced power semiconductor offerings?

As the momentum for carbon neutrality grows, global demand for highly efficient power semiconductors is expected to increase by 200% by 2027 (Source SA automotive and Fuji Keizai non-Auto).

Our new IGBT products will contribute to reducing power losses in EVs and other markets such as industrial motors, EV chargers, UPS, PV and Wind turbines. Once our new 300mm production line at the Kofu Factory reaches mass production, the total production capacity of Renesas’ power semiconductors will double.

Renesas will continue to contribute toward decarbonization by enhancing its production capabilities for power semiconductors such as IGBTs and Power MOSFETs thereby supporting our customers to design innovative, higher-efficiency products.

As mentioned earlier, Renesas has also been investing heavily in wireless BMS, which offers advantages in maintenance and upgradability for EV batteries as well as enabling 2nd life applications such as energy storage solutions and uninterruptible power supplies thereby supporting reuse, recycling and decarbonization efforts.

renesas-batteryWhat is unique about Renesas’ initiative named, ‘Winning Combinations’ and how it has been helping customers in their design ideas and processes?

Winning Combinations are expert designs showcasing Renesas’ complementary product portfolios of Embedded Processing, Analog, Power, and Connectivity which include a reference board, model, software, and design data. These solutions help shorten development time for customers by as much as 2 years.

Our winning combinations come as a result of the broad synergistic portfolio. They enable customers to minimize the process of design, simulation, production, and evaluation of their initial prototypes. This improvement in customer experience is aligned with our Purpose “To Make Our Lives Easier”.

Lastly, what are the current challenges in the EV space and how does Renesas aim to bridge the gaps?
