Nidec and Renesas Collaborate on Semiconductor Solutions for Next-Generation E-Axle for EVs

Nidec Corporation (TSE: 6594; OTC US: NJDCY) and Renesas Electronics
Corporation (TSE:6723) have agreed to join forces on the development of
semiconductor solutions for a next-generation E-Axle (X-in-1 system) that
integrates an EV drive motor and power electronics for electric vehicles

Today’s EVs are increasingly adopting the 3-in-1 unit called E-Axle, which
integrates a motor, inverter, and gearbox (reduction gear). To realize
high-performance and efficiency as well as smaller size, light weight and
lower cost, and to accelerate vehicle development, EVs are also integrating
power electronics controls such as DC-DC converters and on-board chargers
(OBCs). EV manufacturers in advanced markets such as China have developed an
X-in-1 platform that integrates multiple functions, accelerating the
adoption in many vehicle models.

As X-in-1 integrates multiple functions and increases in complexity,
maintaining a high-level of quality in vehicles becomes challenging. Thus,
developing preventive safety technologies such as diagnostic functions and
failure prediction is crucial for ensuring safety and security in vehicles.
To address this challenge, the two companies agreed to combine Nidec’s motor
technology and Renesas’ semiconductor technology to jointly develop a highly
reliable and high-performance proof of concept (PoC) for the X-in-1 system.
The PoC is designed to support the industry’s highest performance and
efficiency as well as smaller size, light weight and lower cost for the
X-in-1 system.

The companies plan to launch the first PoC by the end of 2023, which will
feature a 6-in-1 system with a DC-DC converter, OBC, and power distribution
unit (PDU) as well as a motor, inverter, and gearbox. As a second phase in
2024, Nidec and Renesas plan to develop a highly integrated X-in-1 PoC that
incorporates a battery management system (BMS) along with other components.
The first PoC will include power devices based on SiC (silicon carbide), and
the second PoC will replace the DC-DC and OBC power devices with GaN
(gallium nitride), offering excellent performance in high-frequency
operation, to further reduce size and cost.

Building on the PoC developed through this collaboration, Nidec plans to
rapidly productize E-Axle systems to add to its portfolio and ramp up to
mass production to lead the E-Axle market.

Renesas plans to develop and deliver turnkey solutions for increasingly
complex X-in-1 systems by expanding the jointly developed PoC for E-Axle
reference designs.

“As we celebrate Nidec’s 50th anniversary, we take on a significant
challenge of developing a world-class next-generation X-in-1 system, which
goes back to our core principle of pioneering the world’s best innovations,”
said Mitsuya Kishida, Executive Vice President and Executive General manager
of Automotive Motor & Electronic Control Business Unit at Nidec. “By
harnessing our strengths in automotive technology and developing PoCs
together with Renesas who is a leader in automotive semiconductor solutions,
we aim to lead the market as a world-leading E-Axle provider.”

“We are very pleased to announce our collaboration with Nidec, who has an
exceptional track record of success in E-Axle traction motors,” said Vivek
Bhan, Senior Vice President, Co-General Manager of High Performance
Computing, Analog and Power Solutions Group at Renesas. “Our contribution to
this collaboration extends beyond hardware design, encompassing software
development which is critical to enabling rapid development of PoCs for our
