In order to see how different relocation strategies including relocation for charging and relocation for balancing the demand. I use a simulator to simulate real traffic situation in the city of Turin in Italy. I generate thousands of real FFCS trips in given time period. Firstly, by posing three different kinds of charging relocation strategies that choose charging poles when finishing trip, I observe their performance and study the which additional cost which relocation operation bring. Post charging relocation are also called reactive relocation in the thesis. Next, my partner and I consider ‘proactive’ relocation. In that way, relocation is not only happened at the end of each trip, but can be scheduled and operated in a given time frequency.
