Abstract
The electric vehicles (EV) battery pack quantity planning under the mode of centralized charging and unified distribution is researched. According to the differences between original usable information and the demand of planning objectives, the planning is divided into plannings for two stages, namely the near-term planning and the long-term planning, and corresponding models are established to form a comprehensive EV battery pack quantity planning model covering multi stages. Firstly, the long-term planning is performed, which preliminary estimates the most battery pack quantity that the centralized charging station should purchase according to relevant statistical parameters of EV operation to provide guidance for the near-term planning; secondly, based on the forecasted curve of maximum daily charging demand the near-term planning decides daily distribution times and logistics capability according to a certain logistics distribution principle; finally the EV battery pack quantity of the centralized charging station in the near-term planning is attained. Case study results show that the smaller the variance of battery swapping curve, the lower the distribution rate of battery pack is, and the higher the battery pack will be. Besides, the impact of logistics distribution scheme on battery pack quantity planning is crucial adjective.
