REDSEL Electric Vehicle Architecture Innovation by Silicon Austria Labs

Engineers behind REDSEL electric vehicle architecture have introduced a new way to rethink onboard electrical systems by combining high- and low-voltage domains into a unified, fail-safe framework. Developed through collaboration between Silicon Austria Labs, Infineon Technologies Austria, and AVL List, this approach aims to simplify system design while enhancing operational safety. The concept focuses on reducing redundancy without compromising reliability, which is critical for next-generation electric vehicles.

Dual High-Voltage System Redefines EV Architecture

The REDSEL project introduces a system built around two high-voltage batteries that dynamically balance energy loads. This dual-battery setup allows continuous operation even if one unit encounters a fault, significantly improving system resilience. By shifting reliance away from traditional architectures, the design opens possibilities for eliminating the low-voltage battery entirely. Such a transition could reduce component count, weight, and maintenance complexity in electric vehicles deployed across Austria and beyond.

Advanced Power Electronics Enable Compact Design

Central to this innovation is a compact multi-input power converter that efficiently manages energy flow between the batteries and vehicle subsystems. The integration of advanced semiconductor technologies, including silicon carbide MOSFETs and OptiMOS devices, enhances switching efficiency and thermal performance. These improvements contribute to a smaller footprint and better energy utilization, aligning with broader trends in Semiconductors and Automotive Electronics for EV applications.

Fail-Safe Strategy Improves Reliability and Scalability

Fault tolerance is a defining feature of the REDSEL electric vehicle architecture, ensuring uninterrupted functionality even under adverse conditions. The system’s ability to isolate faults and redistribute loads supports safer operation and easier scalability across different vehicle segments. This makes it adaptable for evolving EV platforms and future mobility solutions, where reliability and flexibility are key performance indicators.

Implications for Future Electric Vehicles

Adopting such integrated electrical systems could reshape how manufacturers design and build electric vehicles. Eliminating the low-voltage battery not only reduces hardware complexity but also simplifies wiring and energy management strategies. As automakers continue to explore efficient architectures, innovations like REDSEL provide a pathway toward more compact, cost-effective, and robust EV systems.

Frequently Asked Questions

What is REDSEL electric vehicle architecture?
