Renesas Electronics Corporation (TSE: 6723)* today announced what it claims is the world’s first “8-in-1” proof of concept (PoC) for E-Axle systems for electric vehicles. It controls eight functions using a single microcontroller (MCU). Developed in collaboration with Nidec Corporation, this PoC integrates a motor, a reduction gear, an inverter, a DC/DC converter, and an on-board battery charger (OBC). System-level testing was also completed to ensure its performance. This of course waits verification in deployments on the road.

“The E-Axle is a unit in EVs that combines a drive motor, a gear, and an inverter. By integrating multiple functions, the E-Axle system can reduce system size and weight, simplifying EV design. Renesas provided key components, including semiconductors and a reference design for the new 8-in-1 E-Axle system. Renesas also plans to deliver turnkey semiconductor solutions for various X-in-1 systems based on the reference design verified through this PoC. Armed with these solutions, developers can implement and evaluate X-in-1 systems instantly, accelerating EV development,” Renesas said.
