The rapid electrification of mobility has driven a fundamental evolution in high-voltage (HV) powernet and converter architectures across battery-electric (EV), hybrid, and fuel-cell electric vehicle (FCEV) platforms. This presentation provides an expert overview of current system-level design approaches and integration strategies, illustrated with real-world implementations. Drawing on practical experience from recent heavy-duty fuel-cell projects—such as those developed for the Nikola truck platform—the talk highlights key considerations in HV system design, including topology selection, converter placement, and thermal management. A special focus is placed on comparing detached versus integrated converter architectures, thermal and electrical integration in the e-powertrain, and addressing FCEV-specific challenges such as water and thermal management, system complexity, and balance-of-plant design.
In this session you will hear about:
- High-voltage system topologies and converter integration
- Design trade-offs in fuel-cell and battery-electric platforms
- Thermal and electrical integration strategies
- Real-world architecture examples from heavy-duty applications
- Future trends shaping next-generation mobility platforms
