Title: Energy impact evaluation for eco-routing and charging of autonomous electric vehicle fleet: Ambient temperature consideration

Abstract

This paper studies the heterogeneous energy cost and charging demand impact of autonomous electric vehicle(EV) fleet under different ambient temperature. A data-driven method is introduced to formulate a two-dimensional grid stochastic energy consumption model for electric vehicles. This model aids in analyzing EV energy cost and describing uncertainties under variable traffic and ambient temperature conditions. According to this energy consumption model, an optimal eco-routing and charging decision making framework is designed for autonomous EV fleet. This optimization framework can improve the capability of autonomous EV's energy management and help to find their minimum energy cost routes with consideration of charging demand and travel time requirements. Based on these promising models and technologies, comprehensive case studies are performed on a data-driven simulated transportation network in New York City. Detailed results show us the heterogeneous energy impact and charging demand under different ambient temperature. By giving the same travel demand and charging station information, there may be more than 20% difference of overall energy cost and 60% difference of charging demand in a specific charging station between low and high ambient temperature of a month. All these studies will help to construct sustainable infrastructure for autonomous electric vehicle fleet management.
