Energy Packet Reservation and Optimization System for Electric Vehicle Energy Cost and Charging Station Peak Demand Reduction

As electric vehicle adoption increases, charging stations will face greater demand and have greater energy needs. This paper outlines a system for reserving electric vehicle charging, using a reservation called an energy packet. The proposed energy packets are composed of the charging duration and the charging energy. Using energy packet reservations from EV users as part of the inputs, this paper developed a charging management system through a charging optimization algorithm to achieve reduced total charging costs for each electric vehicle. A case study is presented to demonstrate the effectiveness of the proposed method in reducing charging costs, peak demand, and greenhouse gas emissions of a charging station.
