Application of Distributed Power Modules on 42 Volt Systems

摘要

Today's advanced electrical systems include more high power loads than ever before. Wiring harnesses are getting more complex, and often represent a significant warranty cost. Dual voltage systems (12V/42V) introduce new architectures that require multiple energy storage devices for different voltage requirements. One strategy for solving the challenges of dual-voltage and high-power loads is distributing power modules throughout the vehicle. The use of multiple energy storage elements buried throughout the vehicle demands that the energy storage technology selected must have long life, low maintenance, flexibility of sizing, wide temperature range, in addition to excellent performance. Ultracapacitors are a premier technology being designed in today as a fundamental element in distributing power throughout the vehicle, increasing reliability and improving per ormance, while simplifying numerous aspects of design.
