Many airports are converting their ground fleets to electric vehicles to reduce greenhouse gas emissions and increase airport operation sustainability. Although this paradigm shift is relevant to the environment, it is necessary to understand the economic feasibility to justify the decision. This study used life-cycle cost analysis (LCCA) to compare the economic performance of electrified ground fleets in the airport with a conventional fossil fuel fleet. Three different charging systems (plug-in charging, stationary wireless charging, and dynamic wireless charging) for pushback tractors and inter-terminal buses at a major hub airport were considered in the analysis. Although the conventional fossil fuel options present the lowest initial cost for both fleets, they cost most in a 30-year analysis period. Among three electric charging infrastructures, the plug-in charging station shows the least accumulative cost for pushback tractors, and their cost differences are negligible for inter-terminal buses. Although the electric ground fleet is proved to show economic benefits, the most cost-effective charging infrastructure may vary depending on driving mileage and system design. The use of LCCA to analyze new systems and infrastructures for decision making at the project level is highly recommended.

许多机场正在将其地面车队转换为电动汽车，以减少温室气体排放并提高机场运营的可持续性。尽管这种范式转变与环境有关，但有必要了解经济可行性以证明该决定的合理性。本研究使用生命周期成本分析 (LCCA) 来比较机场电气化地面机队与传统化石燃料机队的经济表现。分析中考虑了主要枢纽机场的后推式拖拉机和航站楼间巴士的三种不同充电系统（插入式充电、固定式无线充电和动态无线充电）。尽管传统化石燃料选项的初始成本最低，但在 30 年的分析期内，它们的成本最高。在三种充电基础设施中，插电式充电站对后推式拖拉机的累计成本最低，而对于跨终端公交车，其成本差异可以忽略不计。虽然电动地面车队已被证明显示出经济效益，但最具成本效益的充电基础设施可能因行驶里程和系统设计而异。强烈建议使用 LCCA 来分析新系统和基础设施，以便在项目级别进行决策。
