064	Advanced Inverter Topologies Drive Efficient BEV Architectures Ayman Ayad･Philip Brockerhoff (Vitesco Technologies)･Takuya Mimori (Vitesco Technologies Japan) The new wide-bandgap technology such as Silicon Carbide (SiC) and Gallium Nitride (GaN) have recently entered the market of standard Silicon (Si) semiconductors as the main technology within automotive High-Voltage electronics. The new technologies enable advanced inverter topologies such as multi-level and multi-phase for automotive applications. In this presentation, standard and advanced inverter technologies and topologies will be introduced by analyzing system efficiency and cost.
065	Next Generation Cells for Future Battery Systems Hendrick Löbberding･Matthias Rudolph･Jannis Kuepper･Michael Stapelbroek (FEV Europe)･Thomas Hülshorst (FEV Group) Solid-state battery cells are the "next big thing" in electric vehicle technology to solve range anxiety, fear of hazardous incidents, and lacking charge infrastructure. However, technical maturity, production cost, and performance challenges remain. This presentation provides an overview of the state-of-the-art landscape for different cell chemistries and focuses on volumetric energy density as a key attribute for future cell roadmaps. Solid state cells can deliver the needed energy density, while the integration into the pack is rather cell-chemistry specific. Moreover, lesser energy density requirements may choose sodium-ion or LMFP chemistry as a cost-efficient alternative.
066	Power Loss Reduction Method by Power Route Distribution for In-Vehicle Power Net Hiroshi Nakano･Nobuyasu Kanekawa (Hitachi)･Kentaro Jumonji (Hitachi Astemo) This study provides a current dispersion method that avoids the local current concentration of the automotive power network to reduce the weight of the power supply line of the automotive power network compatible with zone architecture. This paper shows an algorithm that optimizes the power supply route to each zone using graph theory and the evaluation results by co-simulation with the electrical model.
