Optimal Planning of Charging for Plug-In Electric Vehicles Focusing on Users’ Benefits

Abstract

[...]estimating the cost of battery capacity degradation is necessary, and then we can obtain the actual total operating cost of EVs instead of considering the electricity cost only. For EV users, they care more about the battery capacity degradation of individual charging. [...]the cost model of battery capacity degradation should be built with the number of charging times, as well. [...]the cost model of battery degradation, which reflects the cost of battery capacity degradation of one time charging for a certain SOC range, can be achieved by combining Equations (1), (3), (4), and (6): Cbattery=(pnew−pused)(100−CRR)×Q×ΔSOC2000×[3.25SOCmean(1+3.25ΔSOC−2.25ΔSOC2)100−CRR]2.21 It is necessary to mention that the result of this cost model is a rough value. Since the battery capacity fading mechanism is an extremely complex chemical process, we cannot achieve an accurate result with existing technologies. Irregular Routes Planning Simulation For irregular routes, EV drivers focus more on waiting time since the destinations are always busy areas, such as shopping malls. [...]reducing waiting time is given priority by the proposed queuing theory and SOC range planning.
