Sizing and Locating Planning of EV Centralized-Battery-Charging-Station considering Battery Logistics System

Characteristics of two types swapping electric vehicles (EVs) are considered, which include private EVs and electric taxis. Then, a time-space load forecasting method for these swapping EVs is proposed. After that, the forecasting results are taken as the load basis for sizing and locating planning of centralized-battery-charging-stations (CBCSs). In addition, based on the life cycle cost (LCC) theory, a double-layer planning model is established. It takes into account the CBCSs’ planning economy and the optimization for battery logistics system. That is, the planning LCC of CBCSs is conducted by the upper layer optimization. And the lower layer planning optimizes the annual transportation cost of the battery logistics company. The calculation example shows that the proposed planning method for CBCSs is feasible and effective.
