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…
