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 micro-controller (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 awaits 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. Continue reading
VW Ensnared in More Takata Airbag Shrapnel Recalls
Volkswagen Group of America is recalling 2017-2019 model year Beetle, Beetle Convertible, 2012-2014 Passat, 2017 Passat Wagon, and 2006-2007 Passat Sedan vehicles, according to documents made public today by the National Highway Traffic Safety Administration. Volkswagen had been refusing to recall the inflators arguing since 2020 about NHTSA’s interpretation of Takata defect data.*
“The driver’s side frontal air bag inflator may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling,” VW said in the required safety defect recall filing. Volkswagens included in this recall are equipped with the Takata SDI-D driver frontal airbag. “An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death,” VW acknowledged.
