Abstract The potential fuel savings of hybrid vehicles strongly depend on the energy management strategy, which distributes the required power between the prime mover and the additional power sources. Here, it is necessary to take into account the efficiencies of the whole propulsion system. In this paper, a novel operating strategy is developed that considers the efficiencies of all major components of the propulsion system. Fuel-optimal load points are calculated off-line by using a numerical sensitivity analysis which takes the fuel consumption as well as the variable state of charge of the energy storage system (ESS) into consideration. Using these fuel-optimal load points, the optimal operating strategy is determined by means of an optimization approach which depends on the duty cycle itself.
