Creating an optimal route planning system for electric vehicles is multi-disciplinary and requires profound knowledge of electric vehicles, batteries, route plan-ning algorithms, and dynamic optimization. Energy efficiency and bat-tery conservation are the main goals of the proposed optimal route planning system.
This work shows that route planning specifically designed for electric vehicles has more to offer than conventional routing systems, which only consider time or distance to the destination. The multi-objective optimization has three aspects : energy consumption, journey time, and battery lifetime.
In contrast to conventional routing sys-tems, which determine the shortest distance or the fastest path to a destination, this work designs a route planning specifically for electric vehicles by finding an energy-optimal solution while simul-taneously considering stress on the battery.
The approach in this paper evaluates battery degradation by minimizing the total energy flow of the battery and therefore the number of charging cycles over the battery’s lifetime, which is different to arriving at the destination with the highest state of charge possible, which is essentially the first aspect of the multi-objective optimization.
Topography has a strong influence on energy consumption and battery operation and therefore the choice of route. The algorithm finds different results considering different preferences, putting weights on the decision variable of the multi-objective optimization.
For the optimization problem, weights are assigned to each variable in order to put emphasis on one or the other. The route planning system is tested for a suburban area in Austria and for the city of San Francisco, CA. Topography has a strong influence on energy consumption and battery operation and therefore the choice of route.
