Abstract

Energy management in hybrid electric vehicles in non-road application is the superordinated control of the overall energy flows and influences the system behavior of the powertrain significantly. Minimization of the overall energy flows, exhaust emissions as well as fuel consumption are the primary objectives of the EMS, while all physical constraints of the system need to be taken into account (Sciarretta and Guzzella 2007). Due to the multiple energy conversions from and into the battery, the minimization of the losses is essential and can only be achieved by an optimization of the overall system. However, the overall system is strongly nonlinear in general and differs significantly between different applications. A generic EMS in terms of applicability and cost reductions is therefore favorable. In this chapter, the energy management system is described in detail and methodologies to improve the EMS performance are introduced.
