Electricity costs for an electric vehicle fueling station with Level 3 charging

Electricity costs for a Level 3 electric vehicle fueling station integrated with a building

“…Prior work that examines a public Level 3 EVSE stations powered through a dedicated utility meter has shown that the cost to purchase electricity under real utility rates can be prohibitively expensive when demand charges are applicable and PEV traffic is low, or if no parking management occurs [55]. This work also showed that demand charges become relatively small when a large number of PEVs are refueled, i.e., when a demand charge is shared by many customers.…”

“…This current work is an extension of the work presented in [55], and attempts to answer the question of whether integration of Level 3 EVSE with a building leads to lower PEV refueling costs? Fig.…”

“…1 shows a schematic of the scenario considered in the prior work [55], where the EVSE is powered through a dedicated utility meter, and in the current work, where the EVSE and a building share the utility meter. The models developed in [55] that describe PEV travel patterns based on the U.S. National Household Travel Survey (NHTS) [56] and possible EVSE operation scenarios that span most types of public EVSE operation are used to produce an electrical demand load profile for Level 3 EVSE. This load profile is then combined with a building energy model using real building data for summer and winter [57] to produce a combined building and EVSE load.…”

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

“…Similar to the work done before, 1000 EVs are generated by the MC method with initial SOC, battery capacity, arrival time, dwell time, and distance to the next destination. The data probability distributions are taken from "The US National Household Travel Survey (NHTS)" [34] and organized in [25]. A shopping area with two charging stations nearby is chosen as an example.…”
