- As powertrain hybridization technologies are becoming popular, their application for heavy-duty military vehicles is drawing attention. The design and operation of the energy management system (EMS) is important to ensure that hybrid military vehicles can operate efficiently, simultaneous maximize fuel economy and minimize monetary cost, while successfully completing a mission. Furthermore, an integrated EMS framework is needed to ensure a functional vehicle power system (VPS) to survive through a mission when needed. This calls for situational awareness and dynamic system reconfiguration capabilities on-board of the military vehicle. This paper will present a new energy management and control (EMC) framework based on situational awareness (SA) and dynamic reconfiguration of the VPS. There are three layers involved in such an EMC operational architecture, namely: the VPS, the SA and dynamic reconfiguration (SADR), and the EMC. The SADR layer provides the state-of-health status of the electrical power sources and sinks of the VPS including generator, energy storage system, propulsion system, and load zones/ports. The EMC layer has two primary functions, namely: selects the power dispatch mode (normal or survival) and accordingly dispatches power to the mission loads based on their respective priorities. Typical results on a notional hybrid ground vehicle power system will be presented to illustrate the functionality of the situational awareness and dynamic reconfiguration for development and operation of the proposed integrated energy management and control framework.
