The REDSEL project introduces a new system architecture that eliminates the conventional 12-volt battery in electric vehicles, relying instead on two high-voltage batteries to manage tasks typically handled by the low-voltage unit. This design employs a redundant architecture with active balancing to enhance load distribution and safety.
Additionally, a compact multi-input power electronics converter was developed to support the new architecture. Utilizing advanced semiconductor technology, including 750 V silicon carbide MOSFETs and OptiMOS-7 components, the project aims to improve reliability while reducing weight and space requirements. The initiative exemplifies effective collaboration between academic and industrial partners, paving the way for future advancements in electric mobility.
