Calculation of route-dependent energysaving potentials to optimize EV’s range
In order to compensate the range disadvantage of battery electric vehicles, it is necessary to make efficient use of the vehicle’s available energy. Knowing exactly how much energy is needed to drive the upcoming route makes this possible. This paper investigates the extent to which driver behavior and the use of the air conditioning system affect the range of battery electric vehicles taking into account the route, environmental and traffic data. Therefore, a methodology is presented which utilizes different measures based on a predictively determined speed profile and provides a remaining, position-dependent energy-saving potential. The aim is to know the remaining energysaving potential at all times during the route guidance. Thus, an assistance system for extending the range can make use of it if the situation requires it.
